Increasingly used by companies in all industries, Cloud Computing is the new form of data storage of the 21st century. There are obviously various options, offers, and services provided by Cloud that may go in a long way for a business and not the other. Nonetheless, Faced with the need for mobility and accessibility of information, our work environments are becoming dematerialized. We are talking about desktop virtualization. This relies on the Cloud to make data or applications accessible from any access point. Cloud computing, in fact, involves harnessing the computing power or storage of remote computer servers that you access through an internet connection. Cloud hosting is increasingly replacing the on-premises servers that are used to host the company’s data locally.
Cloud Server Vs. Traditional Servers
Cloud Hosting refers to the storage and access to data through the internet rather than through the hard drive of a computer. It is thus opposed to the notion of local storage, consisting of storing data or launching programs from the hard disk. Cloud servers and Cloud computing in general, offers several advantages and benefits for business users and end-users.
To be simple and short we can mention three top benefits of Cloud computing:
- self-service provisioning
Elasticity offers the opportunity to increase or decrease the consumption of resources according to the needs of the business.
Self-service provisioning enables end-users to access any IT resource on demand.
Pay-as-you-go allows firms to pay only for the resources consumed.
What is the difference between private, public, and hybrid Cloud server?
In recent years, Cloud Computing has been on the rise. More and more companies are using this way of storing, accessing, and exchanging computer data.
The concept is simple: facilitate the work of all employees by allowing them access to the information they need from anywhere while allowing greater maintainability and security. There are basically three types of Cloud services: Public, private, and hybrid. But what exactly is the difference between the three, and when should you turn to one or the other?
Private or dedicated Cloud Host
In any Cloud system, only your company and your employees will be able to access your resources. Regardless of the terminal used, whether it is a computer, a tablet, or a mobile, whether it is on the premises of the company or outside, you will connect to your Cloud server.
Private Cloud explained: First of all, this is the most common format, private Cloud or dedicated Cloud, both terms are valid, designates an infrastructure that is totally dedicated to you, that is to say, that they are your private server(s) which will manage all of your data and for all the users of your company. This is administered either internally or by a specialist service provider. Your private Cloud, whether it is hosted internally or in a data center, is very close to a local infrastructure.
For most companies, the private Cloud has a fixed cost depending on the type of server used, its capacity in terms of power, storage, and associated maintenance. Sometimes the price can also vary depending on the number of users.
Conversely, the big advantage of the private Cloud is to have much more complete control over its data and its infrastructure. It will indeed be much more suited to its needs, but it may be more expensive.
Benefits of a Private Cloud host:
- It is tailored to your needs your infrastructure
- You don't pay more with more data transfer
Limits of a private Cloud host:
Public or shared Cloud host
- it is less reactive in the event of a rise in load
- it is expensive to set up
Conversely, the public Cloud does not mean that data is accessible to anyone, but only that your data is hosted on a multitude of servers that are themselves accessible by a determined number of users.
Typically, in a public Cloud, you pay for how your data is used. The more information you store, use, or download, the higher the bill will be.
Many companies prefer to use a public Cloud, for the simple reason that you are not limited by the volume of your data. Indeed, companies that offer public Cloud services have a substantial infrastructure and can therefore adapt almost immediately to the increase in your needs. Conversely, it is a limitation that you have on private Cloud for which the installation and the increase in the capacity of the Cloud will inevitably take more time.
One of the big advantages of the public Cloud is that the initial expenses are practically reduced to zilch since you come to graft on the already existing infrastructure.
Benefits of a Public Cloud host:
- it is quick and inexpensive to set up;
- it adapts quickly to the increase in your needs.
Limits of a Public Cloud host :
Hybrid Cloud host
- The more you use the public Cloud, the more you have to pay;
- It is not necessarily adapted to your specific needs and software.
In certain cases, often for large companies with complex needs, we will have a mixed system: this is called the hybrid Cloud.
In this case, the company uses several different Clouds, some public and some private. All of them remain independent entities of each other. In these cases, the interest is extremely easy to understand; it mainly allows data portability between different Clouds, different software, or different entities.
The Main Cloud Computing Models
Infrastructure as a Service (IaaS):
is in fact Provision of IT infrastructure (power and processing and storage space). This solution allows the customer to retain control of operations and applications. This Cloud Computing service requires skills and autonomy from the administrator to manage the operating system, applications, data, etc. IaaS thus makes it possible to dematerialize only the hardware infrastructure.
Platform as a Service (PaaS):
Provision of an IT platform that enables the deployment of customer-owned applications in languages supported by the service provider. This service is a Cloud computing model that provides customers with a complete platform. It enables them to develop, run, and manage applications without the cost, complexity, and rigidity of managing an on-premises platform. The client does not manage the underlying infrastructure (network, servers, storage, etc.). The simplicity of PaaS also allows start-ups to quickly launch their web services and mobile applications without worrying too much about their technical infrastructure.
Software as a Service (SaaS):
A SaaS solution provides the software or application, combining the services of IaaS and PaaS with the addition of installation, maintenance, and configuration included. It is an interface that allows the simple use of the software and does not require a prior computer or technical knowledge. The SaaS software is often in the form of monthly subscriptions. In other words, the company does not own the software but can use it for a subscription.
The question is no longer "should we go to the Cloud?" ", But" how to implement and succeed in this migration? For companies, it is about choosing the model best suited to their needs to meet the challenge of their digital transformation. However, each of the three presents development opportunities for companies; provided that the Cloud is cheaper than a local solution.
