The concept of cloud storage is used to allow you to digitally record data online instead of on your computer or on an external device such as a USB drive or CD. But here are some more specific words on how data storage in the cloud works and what it offers.
Generally, when you save a digital file – be it a photo, a video file, or just a written document – this file is saved on the hard drive of your computer. This effectively preserves the file and gives you easy access. But this system also leaves your data vulnerability to problems. For example, if you save a document on the hard drive of a computer and if it is damaged, corrupt, or even stolen, this document is lost forever! Come on; admit that you are all passed through data loss.
The advantage of the “Cloud server”
The advantage of storing your data in the cloud server is that it allows you to back up your data on servers located via the Internet. When you save a file on your network, the file is placed on servers operated by your provider, whether a technology company like Apple or storage provider like Dropbox. These servers are generally protected by what is best in terms of digital security: data encryption, data transferred between several geographically distant data center, etc. That kind of facility is somewhat impossible to maintain in dedicated servers.
If we bring cloud vs dedicated server concept, we must return to a fact found in many companies. It is not uncommon to discover that dedicated servers are used only 15% of its capacity, but the power reserve and money remain essential to maintain those servers. The result is a significant investment and heavy maintenance on server inventory that gives poor performance than its original capacity. Aggravating factor, a server that is running at 15% capacity is not economical than its potential operator server. We are left with an insoluble problem of energy as we remain in this configuration.
We can group profits in some generic categories:
- For optimal use of resources of machinery (distribution of virtual machines on physical machines according to the respective loads)
- A significant simplification of the initial installation, deployment and migration of virtual machines from one physical machine to another. This is particularly appreciated in the context of a formal production and delivery is facilitated,
- The pooling of machinery has a strong impact on reducing material costs and operational (minimized power consumption, simplified physical maintenance, surveillance, improved support, increased hardware compatibility, etc.)
- Highly virtualized environments simplify installation, testing, development, and allow us to use it at different points without breaking the host operating system configuration.
- The gains in securing a network (the host operating systems are not visible to the attacker).
- Benefits of insulation of different concurrent users on the same machine
- A virtualization also enables dynamic allocation of computing power according to the needs of each application at a time.
- Finally, there is a reduced risk related to sizing servers in defining the architecture of an application.
In conclude we can say, the main advantage of the cloud is the ability to use it only when needed and personalized way.
