Information search in a specialty profile on the Internet, use of cloud services for storage and data processing.


Cloud data warehouses are services that provide the ability to store your files on remote servers, as well as access them from anywhere in the world where there is Internet access. In the conditions of rapidly growing volumes of stored and transmitted information, these services have become popular and in demand by users. Share a photo with a friend, access a book simultaneously on multiple devices, save a backup copy of important information in case of loss or failure of a USB flash drive or hard drive, as well as perform any other actions with information and data thanks to cloud technologies, it has become more convenient Types of cloud services
There are 3 deployment models - private, public (public) and hybrid "clouds". A brief description and main characteristics of these species are given below
Private "clouds" are intended for use within the company. It can belong to the organization itself or be hosted by the provider. This deployment model provides more control and a higher level of security due to the fact that infrastructure components and consumers are located within the same organization. Everything is optimally configured for the needs of this company. However, such an approach to IT infrastructure implies significant expenditures of material, financial and labor resources. By deploying it on its territory, the company will significantly spend on the purchase of hardware and software, on the payment of appropriate IT personnel and administration.
A public "cloud" is provided by a data service provider and can, unlike a private one, be freely used by the general public (for example, Google Drive, Cloud Mail.ru ). When such an IT infrastructure is located on the supplier's territory, it eliminates the costs of hardware and software, as in the case of a private "cloud", and their maintenance. To access the services, you only need the Internet. For companies, this deployment model is also advantageous to use because the risks of downtime associated with server failure disappear. The provider's powerful and high-quality equipment is always under the control of qualified personnel. The disadvantage of the public "cloud" in the first place is the lack of control on the part of the customer of services. Low performance, data transfer speed and weak data security will also not attract a serious company to sign a contract with a provider of such services. Mainly, these "clouds" are intended for private use — file sharing, sending messages.
Hybrid "clouds" combine the infrastructures of the above-mentioned models. Providers provide part of the services as a private "cloud", and part as a public one. This combination allows you to save on the organization of your own infrastructure, but at the same time get control and a high level of security.
Advantages and disadvantages of individual cloud services
Advantages.
Of course, the main advantage, a distinctive feature of cloud data storage, any deployment model, is the ability to access data from any device with Internet access. Users have the ability to publish their files, share them, edit them, view them in the browser. The cloud service also keeps a history of file changes. They also have the ability to synchronize folders between devices — a personal computer, smartphone, tablet, etc. Cloud storage allows you to organize shared access to a file for viewing or editing by setting a certain circle of people by the user.
Data security is guaranteed through the use of backup disks with copies of files by the provider of "cloud" services. To protect user data from being viewed by third parties, encryption of this data is used. Depending on the service, the key can be stored on the server side or on the user side. In the first case, the system ensures the confidentiality of the key and data by decrypting them for the user. In the second case, the protected data can only be decrypted by the user himself or by the one to whom the user will personally give the key. However, if this key is lost, the user himself will be unable to decrypt them.
Cloud storage services can also provide tools for developers and application programming interfaces (APIs). Such tools are used in the development of third-party services and enterprise applications that use the space and functions of existing cloud data storage.
Disadvantages.
- There is a possibility of information theft during data transmission.
- Depending on the provider's services, data leakage may also occur.
6. Comparative analysis of cloud storage
The type of "cloud" depends on the restriction on the storage of information — the amount of disk space, the maximum file size, etc. The public "clouds" discussed in detail in this article make it possible to store a certain initial amount of data in your personal space for free. Some of them also provide the possibility of free expansion of disk space.
In conclusion, it should be pointed out that cloud data storage is very necessary in our time. In confirmation of this, a number of reasons can be cited: lack of hard disk space, not the durability of the OS, "running around with a flash card" and so on.
The paper states that cloud storage is a kind of online service that provides the ability to store files on a remote server. The paper also shows the pros and cons of these programs. The main advantage is that there is access to your data from anywhere in the world where there is Internet. The main disadvantage is the security and confidentiality when transmitting or receiving data.
