Cloud computing is the set of online storage systems. It generally allows to store of computer data on remote servers or computers. This means that it is accessible only on the web. But how does it work? What are the different types of Cloud? And what are its advantages? So, without further ado, let’s dive into this blog and learn some of the things everyone ought to know about Cloud computing.
How does Cloud Computing work?
Cloud Computing is based on a technology called “virtualization”. This technology allows the creation of a virtual computer, simulated, behaving exactly like a physical computer with its own hardware. This is called a “virtual machine”. Several virtual machines can be hosted on the same physical machine, separated from each other.
These virtual machines do not interact with each other, and the files and applications of one are not visible to the others. Virtual machines efficiently use the hardware on which they are hosted. A single server becomes a multitude of servers, and a data center becomes capable of serving many companies.
This allows Cloud providers to offer the use of their servers to many customers simultaneously, at an extremely low cost. Even if one or more servers fail, the Cloud servers remain available and functional. This is because providers typically back up their services on multiple machines across multiple regions. Users access cloud services through a web browser or application and connect to the Cloud via the internet. So this is a technology made possible by significant innovations over the past few years.
Cloud computing: does it really matter?
Nowadays, cloud computing has become indispensable, as it is a solution for providing online services. Individuals and especially companies now use this system. It allows you to free up your hard drives because the storage is done online.
What is the principle of operation of cloud computing?
For your information, cloud computing is a system of services. In other words, it consists of 2 essential elements:
- The connectivity: via optical fiber or network cables
- The server: on which the computer data will be stored. This one is equipped with a great
- performance, well secured, and functioning via applications, software, and operating systems regularly updated.
Only the customer can access his personal data.
You should also know that the server is the property of a provider. And it is the latter who sells the services to the Internet users. This remote computer is protected against computer virus attacks. In addition, the provider offers an automation option to the users. Thus, they can easily manage the network and the remote server according to their needs.
What are the different kinds of clouds?
There is a wide range of clouds in the market. Most of them can meet customers’ expectations. Here is a list of the most used ones:
Public clouds
These allow for the online storage of computer data on servers. But these are accessible to a limited number of people. The rates on public clouds are generally estimated according to the volume of data stored on the remote server.
Private clouds
Unlike public clouds, the private Cloud is an online storage system of an entity. It is the deal for companies wishing full control over their applications, software, and data stored on their servers. In addition, this type of cloud computing can be managed by other providers and placed in a location other than the one that houses the company.
Hybrid clouds
As the name suggests, the hybrid Cloud is a mix of a public and a private cloud. More and more companies and individuals are using this type of Cloud because this system can store 2 kinds of computer data:
- Confidential or sensitive data: which is stored on the private Cloud;
- Non-confidential data: which is mainly stored in the public Cloud.
What are the advantages of cloud computing?
There are many advantages of cloud computing:
Easy to access
Cloud computing offers access to storage services and all applications. It is accessible via an internet connection and support.
A flexible system
Cloud computing can be easily adapted to all the needs of the user. The latter can manage his storage space and the computing power he needs. You only have to pay for the amount of storage you need to store your data.
No upfront financing
Whether it is application or hardware, the use of cloud computing does not require a significant investment. In other words, the user only pays a monthly subscription.
