Cloud technologies. Cloud technologies in optimizing business processes company Benefits of cloud technologies for users

In the modern world, informational technologies of the main criterion of their choice are mobility. People are important to have access to their data from anywhere in the world and be confident in their preservation. Especially when it concerns the sphere of video surveillance. Cloud services come to replace local video surveillance.

Video surveillance, as a cloud-based service, is a model that allows you to work with video by connecting to servers remotely via the Internet. Control and management of servers and communication channels is carried out by companies - cloud service organizers.

Cloud video surveillance is a video surveillance over the Internet, which allows you to save, view, analyze and combine geographically scattered cameras into one system and manage access to their video archives.

Currently on the market available two main types of cloud solutions In the field of video surveillance:

Service based on the equipment of the manufacturer of IP cameras;
Universal service from cloud solutions.

Consider more each of them.

Service based equipment manufacturer IP cameras

With this type of service, the cloud is developed by camera manufacturers and only works with its devices. To connect to the cloud on this model, the user needs to buy a special "smart" camera and simply enable it on the network. The camera will independently establish a connection with the service and register in the Personal Office of the User.

For service providers based on the equipment manufacturer of IP cameras, there are two nuances that need to be taken into account:

First, it is limited selection of camera models and dependence on equipment supplier. For example, a change in price can significantly affect the final amount of the purchase, especially if the user needs to establish a video surveillance in several places.
Secondly, most of the representatives of this type are present speed limit (The working capacity of the cloud is limited to the functionality of the camera), which causes low image quality.

Universal service from cloud solutions

This group includes cloud services that provide company-developers directly to users. Those in turn can choose from a variety of solutions options - IP cameras of different manufacturers. To start using, you only need to connect the camera to the video surveillance cloud service, register with the system and start work.

This type of service allows you to build video surveillance systems from chambers of various manufacturers and is suitable for both small objects that do not require complex solutions and large-scale projects. All developers companies are mostly the same set of functions, their proposals differ only in tariff plans, degree of reliability of systems, as well as convenience of connecting and operating.

The main advantages of cloud video surveillance

Simplify access to the camera and archive. For the video surveillance system, it does not require a static IP address or a specific network configuration, and you can view the online video and archive from anywhere in the world where there is an internet connection.

Ensuring data storage. The video is stored in powerful servers in geographically distributed data centers. In addition, all traffic is fully encrypted by a specialized processor in accordance with the SSL standard, which is used when making banking operations. In the cloud archive, the data is duplicated on servers in different data centers, and in case of problems on some of the servers, will not be lost. There will also be no problems with the ended platter on the disk: all videotapes will be saved.

Obtaining additional features. Also in the cloud storage of the video there is a useful feature set, for example, the ability to transfer access rights to other users of the service. The same service may offer operational push and email-notifications of sound and movement in the observation zone, as well as video status video analytics.

The possibility of organizing geographically remote video systems. Cameras that are located in different points planets are easily combined in one personal account of the user, thereby ensuring the convenience of control and operation of the system. Some services even allow you to place objects on GoogleMaps map and thereby visualize their location.

Lack of capital costs. Data storage services that provide data centers allow companies to reduce capital investments and operating costs, so no additional cost-maintenance and server maintenance is required. The fee is charged only for the storage of the cloud archive.

Summing up, I want to say that cloudy video surveillance is an effective tool that can optimize many areas of our life.

ABSTRACT. The Article Considers The Advantages and Shortcomings of the Use of Cloud Technologies AS Well As The Main Aspects of their Construction. The Importance of Cloud Services for Automation of Modern Business Is Proved.

Keywords: Cloud Technologies, Cloud Computing, Service Provider, Internet.

The development of a modern innovation economy is inextricably linked to the use of computing equipment, creating information systems for various purposes. The high need for information for management purposes and the rapid development of information processes has highlighted the creation of components of its infrastructure covering computing techniques, means of communication, methodical and software, technology auxiliary activities. One of the most important elements of this infrastructure is currently cloud technologies.

The topic of cloud computing today is one of the most relevant. Like all new ideas that are able to change the established methods and rules for organizing and creating decisions, the "cloud" approach has both supporters and opponents. The case is not limited to one debates and reasoning. There are already a number of ready-made solutions and technologies that allow both a local computing cloud, within the enterprise, and the use of resources already existing, adapting their solutions to the possibility of their implementation in the cloud. We will consider the main aspects of building cloud technologies, their significance in the automation of modern business, as well as the main advantages and disadvantages of using Cloud Computing.

It is believed that the theory of cloud computing originated in 1960, when D. McCarthy announced the assumption that someday computer calculations would be

implemented with the help of nationwide utilities. The ideology of cloud computing received fame in 2007 due to the rapid development of communication channels and increasing in the geometric progression of the need for business and private users in horizontal scaling of their own information systems.

In April 2011, the Analytical Firm Forrester Research presented a forecast for the development of the market for public cloud computing until 2020. According to the report, by 2020, the volume of the cloud market will be $ 160 billion (see Fig. 1).

Fig. 1. Predicted volumes of the cloud market.

Cloud computing established themselves, proved the right to exist, they apply to many advanced business and industrial companies.

The essence of the cloud computing concept is to provide end users with remote dynamic access to services, computing resources and applications (including operating systems and infrastructure) via the Internet. The formation of the sphere of hosting was due to the need for software and digital services that could be controlled from the inside, however, which would be the most economical and effective at the expense of savings on the scale.

Computing clouds consist of thousands of servers posted in data centers, providing work of tens of thousands of applications that simultaneously use millions of users. An indispensable condition for effective management such

large-scale infrastructure is the maximum full automation. In addition, to provide various types of users - cloud operators, service providers, intermediaries, IT administrators, users of protective access applications for computing resources, the cloud infrastructure should provide for the possibility of self-government and delegation of powers.

The concept of cloud computing significantly changed the traditional approach to the delivery, management and integration of applications. Compared to the traditional approach, cloud computing allow you to manage larger infrastructures, serve various groups of users within one cloud, and also mean a complete dependence on the provider of cloud services.

The most common examples of cloud applications with which most of us faces everyday life: Skype - service for communicating via the Internet, Yandex.Disk is a service for storing and sharing files.

If we talk about business companies, then initially they endured postal and web servers in the cloud, video conferencing systems, then analysts and financial accounting systems were added. But this list today is far from complete.

One of the first technological innovations underlying cloud computing is virtualization technology. The virtualization of the resource of the physical server allows the most rational to allocate them between applications. Each of them sees only the resources intended for him and suggests that a separate server is allocated, that is, in this case, the "One Server - Multiple Applications" approach is implemented, but the performance, availability and security of server applications are preserved at the same level. In addition, virtualization solutions are the ability to run different OS in sections with the mechanism of emulation of their system calls to the server hardware resources. Virtualization is based on the possibility of one machine to perform the work of a certain number of computers. This becomes possible thanks to the allocation of its resources in several environments. Using virtual machines and servers, you can place several OS and several applications in a single location. Therefore, the problems associated with any physical and geographic restrictions disappear. In addition, the virtual structure has a number of undeniable advantages: energy saving; Optimization of expenses; an increase in the efficiency of using hardware resources; improving job safety; improving the recovery system in unforeseen situations; relatively high availability of resources; Ease of use and management for the user.

Virtualization is although an important, but not the only technology underlying the modern cloud paradigm. Among other technological trends that served as a prelude to modern cloud computing, you can name the service-oriented architecture (Service-oriented Architecture, SOA), providing applications in services (ApplicationService Provider, ASP), ITIL / ITSM and others. Some of these concepts concluded quite specific new technological approaches, while others were mainly used in marketing purposes (for example, ASP).

The widespread spread of high-speed Internet communication channels made it possible intensive data exchange with computers in the cloud. WEB 2.0 technologies maturation made it possible to perform functionally rich web expansions directly in the web browser window, and not run them on the local computer or on the local network. To some extent, the success of cloud computing also contributed to the development of the Internet.

Cloud computing has absorbed a lot of ideas from previous concepts, and therefore initially they are more versatile: they can be understood as a technical paradigm, and as a marketing term, and as a promising direction for R & D and academic studies. In essence, all those ideas that accumulated in the industry have been invested in cloud computing during the previous one and a half decades.

In connection with the relative novelty cloud technologies, the question of the expediency of their implementation causes many disputes and discussions. Take an effective solution to introduce cloud computing - a complex task that requires complete analysis of the enterprise, the environment for which we offer to deploy the so-called remote desktops. We give the most important advantages and disadvantages of using Cloud Computing.

First of all, the most important advantage of use is the low initial investment in IT: it is not necessary to invest in the purchase of equipment, software, configuration and technical support of the network. Representatives of various companies using cloud technologies note that along with improving productivity and efficiency at all levels - both in the office and during remote work, they have received a solution that can grow with the company and expand in accordance with the needs of the business. This decision can be very successfully fit into the business plan of the enterprise. With the help of Cloud Computing, the company receives a solution immediately and at a low monthly rate. So we go to the next advantage when evaluating the use of cloud computing. Optimization of expenses

low fixed monthly fee for using a remote space in the form of a subscription to the necessary services, which is determined by the fact that CLOUD computing allows you to save savings with increasing and inexpensive operation. Software licenses do not need to be put on the balance of the organization, that is, a liability is reduced, since the service provider assumes liabilities and uninterrupted work. Flexibility and scalability of solutions for the organization and reorganization of working with communication and information space is another advantage of using cloud services, one of the important characteristics of scalability is the ability to increase or decrease the network machines in the Working Group. And also add new working solutions. Easy in support, a paid single IT service, which is all inclusive, no need to install and serve servers, update software, take care of the compatibility of programs and hardware. The information space becomes a large, distracted infrastructure, with the ability to distribute resources at which they are allocated and exempt at the requests of the program during its execution, easy transfer of applications to the desired memory cell. Another plus is the lack of long-term contracts and obligations to service providers.

The indisputable advantage is also accessibility from any computer using Internet protocols. Although the ordinary user modern cloud services is still hard to imagine as an alternative to its own hard disk, more often they use them as a link between the home computer and the mobile device. Therefore, manufacturers of computer equipment are trying to attach an increasing number of users to cloud services, developing convenient applications for work and recreation.

Despite the obvious advantages, the concept of cloud technologies is very criticized, and from a variety of parties. The main claims to Cloud Computing in relation to the environment of a single information space and to corporate users are safety, control, instability of cost structure, potential deterioration of business flexibility. The main issues are associated with security, uncertainty in whether data is sufficiently protected in the cloud. And there is no chance that the owner of the data center itself will decide to take advantage of the data trusted. The minus today is also the need for reliable broadband Internet access. There are a number of less obvious problems of using cloud computing: the need to constantly make a fixed

monthly fee, whereas in the case of software operating on the ground, costs are first substantial, but then depreciation occurs; The situation with software products and licenses, located on the server, Cloud Computing is not clearly defined, CLOUD Computing is the least transparent method of providing external services, the management of such a system may become problematic.

One of the most important is the problem of confidentiality - this issue is constantly discussed among the main vendors of cloud computing.

But, if an organization still uses cloud services of a public or private cloud, they must fully comply with the confidentiality of the organization of a single information space in the enterprise and ensure the implementation of all rules and laws. It should also be borne in mind that the so-called set of additional controls, which can be added by the tenant, is limited and does not always allow to close spaces in some cloud services.

Despite all doubts, cloud technologies have ambitious development opportunities. This is confirmed by the fact that this is not a temporary hobby, and the new path of becoming high technologies is the following fact: no matter how strong the contradictions between the three giants representing the platforms of the information space, namely, Microsoft, Apple and Google, whenever the views differed, Directly with cloud technologies, all three companies associate their future. Today, even those people who are not related to the development of programs, web technologies and other highly specialized things may feel the benefits of cloud technologies.

With an increase in Internet connection speeds, services providing ubiquitous and convenient network access to various computing resources and data storage devices are gaining more and more popular. In this material you will learn what cloud computing and what capabilities they provide users.

Introduction

Initially, the name "cloud", computer systems were obtained due to quite innocent simplification invented by the Mathematics programmers. They offered all computers in the composition of the same network to be denoted as a cloud with data depicted inside it. In this case, each computer is not considered as an independent unit, but is part of the whole. Under the integer, the system of the system, which is directly involved when working with the user. Thus, all network resources available to us through servers, in fact, can be called a "cloud".

Cloud Services File Storage

The largest popularity of the "cloud" systems were obtained thanks to the development of services that allow you to store files not in the computer's memory, but in a specially created Internet storage. Such functionality provided users who were unprecedented earlier freedom of choice, because all files stored in the cloud are available to the owner at any time and from any device connected to the Internet. In addition, in this case, it disappears the need to store data on local disks, which can save time (on downloading information and other) and user tool.

Also cloud services can be used as backup storage of personal data. In case of failure of the hard disk of your computer, you can always return all the necessary information pre-stored in the clouds.

No less effectively cloud storage can also be used to synchronize data between different computer devices. For example, you can make changes to the file on the working computer and be sure that all the fixes made will be entered into all its copies stored on other devices that are synchronized with the cloud service.

The most popular client file storage facilities include: Google Disc, Yandex.Disk, Microsoft Skydrive, Dropbox, ICloud and others. Almost all of them after registration provide users with some free file storage (usually from 5 GB to 10 GB). If this seems to be enough, then for an additional fee you can organize a storage with a capacity of 20 GB to several tens of terabytes.

Cloud Software Services

However, the value of cloud computing and their ability to evaluate only as a universal file repository, because their application area is much wider. For example, some cloud services, such as Zoho Docs or Google Documents, are already providing the ability to store not only files, but also of various applications.

The benefits for the creators of such services are very obvious. The developer company receives unlimited possibilities for the implementation of its own software products, while there is no need for the actual transmission of the program itself, it is stored and placed within the cloud. That is why the risk of hacker attacks is minimized, and the technical support program of the program is able to continuously monitor its work, providing stability and ease of use.

Cloud accommodation allows developers to control the legality of the data entering the data server, therefore the risk of distribution and use of illegally produced or simply decreases the counterfeit software. We think you should not remind you about the dangers melting into similar "favorable for download" files. With them, you can get anything in the kit: from fresh trojan to something worse. That is why it is so important to control the origin of the files entering the "cloudy" storage.

One of the bright cloud representatives is the Microsoft Office 365 office package. Includes all the most popular office applications, such as Word, Excel, PowerPoint, and so on, it provides access to your documents from everywhere where there is access to the Internet and allows you to work on them From a variety of devices, even on which the Office package is not installed. In addition, users are able to work together on documents, exchange instant messages and not worry about protecting their own data.

Cloud Computing Service Models

In fact, all the "cloud" systems available to the modern user can be divided into four categories. The first includes the proposal of its own developments in all interested in this users. At the same time, the programs themselves are stationally posted on developers sites and are available only through a network connection. Such a category of systems is denoted by the abbreviation SaaS. (Software as a service) and presented in the form of Adobe Online Services, Google documents, Microsoft Office Live Workspase and some others. Thus, you may not buy expensive software, but to use it for rental rights during the required time.

The second service model has a name PAAS.(Platform as a service) and provides users with access to the cloud to use various information platforms: operating systems, development and testing tools, database management systems and other. In this case, consumers can not only exploit the selected platforms, but also to install their own software on them. For example, so you can try in a new software environment without installing on your own PC.

The third category of services offers to move all the necessary tools to work, including the desktop itself, inside the "clouds", thus providing users with finished jobs, access to which is carried out from anywhere where there is Internet. Such systems are combined with name Daas(Desktop as a service). Options for placing and displaying such a service can be two: either direct access to all applications used, or access links to them. In any case, all the work is carried out only through the browser, and it is impossible to use it.

To date, DAAAs are considered a promising cloud direction and allows you to deploy a full-fledged workplace, ready round the clock to work with all the necessary software. At the same time, all applications are stored in a special data center, which makes it possible to effectively use this tool even on low-power computers, laptops, tablets, and even smartphones.

Last model of service Iaas.(Infrastructure as a service) allows users to independently manage cloud resources, providing for rent as hardware (servers, client systems, network equipment, and so on) and operating systems and the necessary application software. For the most part, this technology is used by corporate clients to create their own cloud computing service.

Disadvantages and advantages of cloud services

Despite quite a lot of positive points in the use of cloud services, it is worth noting certain disadvantages when working with them. Not the most enjoyable user is the news that all its data placed in a "cloud" are in practically free access for law enforcement agencies of various levels (on request, with the request of the data request, no one must notify), as well as software developers. That is, if you wish to learn about you, the maximum information, including from the personal correspondence stored in the cloud or photo / video files, will be able to anyone who has managed a person who has certain powers. You can avoid this unwanted invasion in only one way - to abandon the "clouds" in favor of the local connection through the available software.

An even greater danger of a "cloud" service that does not have enough reliable protection against hacking. In this case, after making a hacker attack, your data not only can get into other people's hands, but also to be completely destroyed.

We add to the dessert that, in addition to accessing your information stored in the "cloud", especially a lucky cracker will be able to get the ability to control the operation of your computer or computers as a bonus (if there are several of them), and this may already entail much more difficult consequences.

So let's summarize. Pros of the use of "cloud" services:

Use by legal origin;
The ability to log in and accessing personal data from any device connected to the Internet;
The possibility of organizing backup data storage;
Data synchronization on all your devices;
Small requirements for source software and technical support of devices for working in cloud services;
Ability to use complex software complexes on low-power equipment.

The inability to control access to third-party stored data;
The need to install an Internet connection with the service every time you need to get access to files or applications;
The need to use the services and suggestions of a certain developer to which the service belongs;
The need for regular pay for some cloud services and services.

Conclusion

Use "cloud" services or leave for yourself the possibility of working with the usual desktop and computer storage system - each decides itself. However, in our age, when only a very naive person, the risks from the use of such innovative developments sometimes exceed the use of the Internet connection. It is worth thinking that one of the following for you is more important: freedom of access to files, the ability to remotely store applications and used tools or data security that can sometimes be very personal. And only if the benefit exceeds the risks, it is worth choosing a "cloud" as an alternative solution to the problem of storing information.

Considering the specifics of the implementation of scientific and educational processes using remote educational technologies, you can allocatethe following advantages of cloud services:

availability to any personal computers and mobile devices, which ensures savings of high-performance software and hardware complexes on the side of educational institutions (cloud services). Cloud service clients can access their workspace at any Internet connection point;

the reliability of cloud services is ensured by the fact that the software and hardware platform is located in specialized data processing centers (data center), which include 100% redundancy of network and hardware infrastructure;

economic benefit. The presence of platforms such as Google Docs does not require the educational institutions to purchase licensed software, its settings and updates.

Disadvantages Cloud servers are:

the need for permanent connection to the Internet. In settlements of distant information and communication centers, the likelihood of technical and technological problems of accessing the Internet can be large. On the other hand, with the development of 3G, 4G technologies, satellite and mobile transport environments This deficiency in the future will be practically excluded;

limit of software scaling. Many cloud services provide a minimum set of tools for configuring the service area. Accordingly, the user often cannot optimally configure its workspace;

inaccessibility to the introduction of these technologies to small companies due to the high cost of software and hardware "Clouds".

The concept of the cloud computing is often considered in two ways, some in it see risks for safety and new "threat vectors", but at the same time this system has new features for improving security. Improved infrastructure observer, automation and standardization - all these possibilities increase the level of information security. For example, if you use a predetermined set of cloud interfaces in parallel with centralized management of identity information, along with access control policies, we are an order to reduce the risk of customer access to unwanted resources. Such security measures such as the execution of computing services in isolated domains, the use of encryption to data, significantly increase the safety of information, reducing its loss. It is worth adding that the use of automatic initialization and the restoration of executable images will reduce the space for attacks by allowing you to solve a number of legal aspects.

How to "increase the number of advantages"?

Safety in the Cloud environment is a fairly difficult task, the reason for the additional risk that occurs due to the fact that it is often important services to provide third-party organizations on outsourcing conditions. This greatly complicates aspects such as the availability and confidentiality of data, maintaining the integrity, readiness of the service.
The Cloud Computing concept provides for the transfer of control over the operations and data of the CLOUD service provider from the client organization. Including the tasks of installing packages of updates, configuring firewalls can go to the Cloud service provider from the end user.
The consequence of this is becoming a need to establish trust relationships with suppliers, assessing the risks, however competently from their behalf, configure and security management will be made. The relationships built according to this principle are of great importance, because customers, even though the workload is in the Cloud environment, is independently responsible for protection and regulatory compliance of its critical data.
It is because of the risks that are associated with outsourcing services, some organizations prefer hybrid or private models in front of the Cloud environments.
Risk and security revisions require other sides cloud computing. The reason for this is the complexity of establishing a physical storage location. Previously visible safety processes in such a system are hidden by abstraction levels, which, in turn, creates problems in the field of regulatory conformity and security.

Serious differences in safety in traditional IT environments and cloud environments are due to both cloud infrastructure cloud-infrastructure. Very often, users who represent completely different organizations and at the same time have different confidence levels, possess the former set of system resources.

Together with these moments of dynamic on today IT environments as leveling workloads andSLA , suggest a large number of data distortions and incorrect configuration.

Of course, a collective use infrastructure requires a high level of automation and standardization of processes, which will facilitate a higher degree of security due to the elimination of opportunities for operator errors.

However, the risks that are peculiar to large-scale collective use of the infrastructure suggest that such moments as isolation, compliance with regulatory requirements and identification data, should be of great importance in the CLOUD computing models.

And yet, what is the main advantage of "clouds"?

One of the main advantages of "clouds" is a decrease in costs. However, some analysts provide examples in which the total total cost of ownership of the "cloud" solution can be higher than in the classical scheme, in connection with this, it is necessary to assess economic efficiency. The initial costs required for the deployment of the "cloud" information system are lower than with a classic approach, but in the future their significant increase is possible. For example, Richard Jersark (Optimal Innovations) and Mark Preston (RS Performance) and Mark Preston (RS Performance) conducted a detailed analysis of the prospects for the online store, the manual of which will have to make a choice: contain your own server or resort to Amazon cloud computing service. For both options, the costs and the amount of energy consumed two years ahead were calculated. These calculations have shown that the cost of the site, which is created using Amazon, will initially be lower than the cost of the internal server. However, over time, they will begin to exceed them, even considering savoible energy. This is explained by the fact that the decision is necessary to the customer not from time to time, but constantly, and all the increasing cloud computing will require more and more computing power, which increases payment for the "cloud". In addition, the rental price includes such costs as the development, support of software, hardware maintenance, and the customer pays the services directly to the supplier itself. As a result, and also considering the above-described risk assessments, it is recommended to work "cloud" projects so that the entire infrastructure to the order is created by the solution provider, according to the principle of the "private cloud", and there was no rent for using this resource. Naturally, it will not be possible to completely abandon the service provider, because technical support is also necessary, and project improvements, and maintenance. However, their cost and labor costs of the Contractor will be similar to the classic scheme, which will not affect the final cost of the project for the customer and, accordingly, on the economic efficiency of the "clouds" in comparison with the usual classic model.
