Companies of all sizes and industries are increasingly moving to the cloud. Gartner forecasts global annual public cloud growth to approach 20% through 2021. According to the research firm, cloud investments are expected to increase 50% by 2022 . But why is this technology so popular? What are the advantages of the cloud for companies?
According to the SecNumcloud reference framework, developed by the ANSSI (French National Information Systems Security Agency), cloud computing can be defined as a computer management model that allows access through a network to shared and configurable computing resources. These resources are allocated on demand and sometimes on a self-service basis. It is the highest qualification in IT security and Oodrive was the first cloud player to obtain it.
The document states that the difference between traditional shared external hosting and cloud hosting is that the latter is sometimes distinguished by the provision of resources dynamically or automatically, without human intervention from the hosting provider.
The cloud, or cloud computing, takes many forms. Each one has its own advantages, depending on the needs of each company. SaaS, PaaS, IaaS – the choice is yours. However, it is important to know the specifics of each system.
IaaS: outsource your hardware infrastructure
What is meant by provision of IaaS services (infrastructure as a service). According to the SecNumcloud framework, this service refers to the provision of abstract computing resources (CPU power, memory, storage, etc.). The IaaS model allows the company to have potentially virtualized outsourced resources . Thus, it maintains control over the operating system, storage, deployed applications and certain network components (for example, the firewall).
With this solution, the company manages the server middleware and application software . On the other hand, the cloud provider manages the server hardware , operating system, virtualization layers, storage, and networking.
PaaS: outsource your
hardware infrastructure and middleware applications
With this solution, the company has no control over the underlying technical infrastructure, which is managed and controlled by the service provider (network, servers, operating system?, storage, etc.). However, the company is in control of the applications deployed on the platform.
In this context, the cloud provider manages the company’s application execution platform, which consists of servers, core software , and infrastructure.
SaaS: the all-inclusive package
What to expect from the provision of SaaS services ? This service, according to the SecNumCloud framework, refers to the provision by a service provider of applications hosted on a shared platform . The company has no control over the underlying technical infrastructure. The service provider transparently manages all technical aspects that require computer skills. One of the advantages of this solution is that it does not require any investment or infrastructure costs, since the service provider takes care of these elements.
The different cloud models and their advantages
Depending on their security needs or requirements, a business can choose a public cloud, private cloud, or hybrid cloud. Each model has its own characteristics. In a public cloud, servers and applications are shared. This solution is especially interesting in terms of cost.
Private cloud is generally preferred in companies with very high requirements or even limitations in terms of security.In fact, this solution is based on the individualization of resources and services. The company can opt for a third way, the hybrid cloud. In this case, the company combines public and private cloud resources. Thus, you benefit from great flexibility and an infrastructure adapted to your needs.
Now that we’ve introduced the cloud in all its forms, it’s time to get to the heart of the matter. Why is this technology increasingly attractive to companies? Accessibility, flexibility, saving time and money… What are the advantages of the cloud?
The advantages of the cloud
One of the great advantages of the cloud is its flexibility . It allows you to develop a cloud infrastructure based on the needs of the company. The capacities subscribed within the framework of your subscription are adjustable to deal with peaks of activity. The cloud can be used to support the development of a business. The company is freed from the limitations linked to its computer equipment, especially in terms of computing power, storage space or number of users.
Agility and accessibility
Among the advantages of the cloud, it is also important to mention agility and accessibility . Cloud solutions can be accessed at any time, from any device, through a simple Internet connection. The cloud is a real asset in increasing the agility and mobility of your employees. Constant access to services allows you to improve collaboration with colleagues or contacts outside the company. In the same logic, mobile and remote work is also facilitated by the deployment of the cloud. The exchange of data in real time allows a real increase in productivity.
speed and simplicity
The advantages of the cloud are speed of deployment and ease of integration . In fact, a cloud solution can be up and running in no time. The service is available quickly. Once installed, cloud applications are often easy for employees to adopt.
Cloud and security, the impossible combination?
Security has long been one of the top barriers to enterprise cloud adoption. But today they have realized the advantages of the cloud, especially in terms of protecting their data. Cloud solution providers can now make a strong case for how secure their tools are. The SecNumCloud qualification, for example, is intended to establish a high level of security that businesses and government agencies should expect from their CSP ( cloud service provider ).
