The system allows an infinite number of times to create, modify, write and delete files, as well as read data and arrange them according to your needs. At the same time, you can set access permissions for individual users and groups, which allows you to control access to information and its security.<\/span><\/p>\n<h2>Benefits of cloud storage<\/h2>\n<p><span style=\"font-weight: 400;\">Cloud data storage has a number of advantages over stationary ones:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Saving time and money.<\/strong> Remote storage of information allows you to minimize operating costs and completely avoid capital investments, since to create your own server for storing information, you will need not only to allocate a separate room for its placement, but also to purchase expensive equipment in the form of servers, racks, cooling systems, additional drives, as well as special software and hire administrators for maintenance, preventive maintenance and installation of updates. With this saved time and resources, you can direct more business-critical processes and actions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Reliability.<\/strong> The cloud storage is maintained by professional security engineers and administrators of the provider, and regular updates. For the safety of client information, space on the server is reserved with a margin, and the servers on which the data are stored are distributed across several cities and countries at once, so that access to them can be obtained even in a force majeure situation.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Complete security.<\/strong> Providers&#8217; data processing centers are located in separate rooms with limited access, constant security, control systems, video surveillance, fire alarms and backup power. The DBMS is reliably protected not only by individual settings of access rights to accounts, but also by a reliable encryption system when loading, unloading and storing files.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Availability.<\/strong> Sharing information does not require changes to program codes and complex settings for integration with services, and data management can be carried out both through the API and through the built-in console or clear graphical interfaces. At the same time, it becomes possible to significantly simplify most of the business processes, because employees can use cloud storage even from home, and the loss of repositories or important documents is completely excluded.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Scaling.<\/strong> Data storage on the Internet allows you to increase the available space almost at lightning speed by connecting additional servers. In physical storage, scaling is possible only if additional space and expensive equipment are allocated. Moreover, only consumed resources are paid for, and there is no need to pay for additional space in advance. Fees can also be flexible depending on the frequency of data access.<\/span><\/li>\n<\/ol>\n<h2>How cloud storage is used<\/h2>\n<p><span style=\"font-weight: 400;\">The cloud for storing files and data can be used for various purposes, the most common of which are the following:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Creation of backup copies.<\/strong> Cloud file storages are compatible with databases, so they are often used to create backups during updates. At the same time, the backup setup will be quite simple, and the data will be reliably protected due to the distribution of copies at once across several data centers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Software testing and development.<\/strong> During the development process for collaboration, many environments are duplicated, and excess data is subsequently deleted. Therefore, software developers often use cloud resources that can be quickly and easily integrated with different applications.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Shared access.<\/strong> Team members of testers or developers are often located in different locations and even countries. In the case of storing data on the company&#8217;s internal servers, a VPN is needed to access them, while cloud storage greatly simplifies this process.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Migration of information to the cloud.<\/strong> It allows you to significantly simplify the maintenance of your own infrastructure and is easily organized by special services.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\"><strong>Big Data.<\/strong> Storing even small amounts of data on a local server is quite expensive, while the <a href=\"https:\/\/unihost.com\/dedicated\/bigdata\/\">BigData cloud server<\/a> is not only cheaper, but also has high bandwidth, the ability to customize queries without fetching data, and minimal load delays.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Also, the <a href=\"https:\/\/unihost.com\/dedicated\/hosting-for-files\/\">data storage<\/a> can be used for the following purposes:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">recording and storing large amounts of information, for example, recordings from CCTV cameras;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">as a repository of content for multimedia and educational resources, public databases;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">storing information on gaming platforms;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">as <a href=\"https:\/\/unihost.com\/dedicated\/database-hosting\/\">a server for hosting databases<\/a> of static sites, blogs, internet portals and shops;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">for content distribution streams (<a href=\"https:\/\/unihost.com\/dedicated\/hosting-for-video\/\">server for video hosting<\/a>);<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">for archiving, storing and further analytics of large amounts of information;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">for machine learning using large datasets.<\/span><\/li>\n<\/ol>\n<h2>Types of cloud storage<\/h2>\n<p><span style=\"font-weight: 400;\">Storing data of various types in the cloud requires special conditions. So it is inappropriate to store together archives of corporate documents, recordings from cameras or Big Data arrays, so the types of cloud storage are chosen for specific tasks.<\/span><\/p>\n<h2>Block data storage<\/h2>\n<p><span style=\"font-weight: 400;\">Block storage assumes the division of recorded files into equal blocks, each of which has its own location identifier, from which, when requested, the system collects a whole document.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These types of storage are used:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">for integration with corporate databases;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">with an indefinite amount of information &#8211;
