What is cloud computing?
C loud computing is the provision of computer resources on demand via Internet, with pricing based on your use. Instead of buying, owning and managing physical servers and data centers, you can freely access technology services, such as computing power, storage and databases, from a cloud provider. such as Amazon Web Services (AWS).
Businesses of all types, sizes, and industries use the cloud for a wide variety of use cases, such as data backup,
disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web applications.
For example, healthcare companies are using the cloud to develop more personalized treatments for patients. Financial services companies are using the cloud to optimize real-time fraud detection and prevention. And video game makers are using the cloud to bring online games to millions of gamers around the world.
The Benefits of Cloud Computing
The agility
The cloud gives you easy access to a wide range of technologies, allowing you to innovate faster and create virtually anything you can imagine. You can quickly use the resources you need, from infrastructure services like compute, storage, and databases to the Internet of Things, machine learning, data lakes, and analytics, etc.
You can deploy technology services in minutes and go from idea to implementation orders of magnitude faster. This gives you the opportunity to experiment, test new ideas to differentiate customer experiences and scale your business.
Elasticity
With cloud computing, there is no need to over-provision resources upstream to handle future peaks in activity. Instead, you allocate the number of resources you actually need. You can instantly scale these resources to scale up and down in capacity as your business needs change.
Cost reduction
The cloud allows you to move from fixed expenses (such as data centers and physical servers) to variable expenses and only pay for the IT services you use. And thanks to economies of scale, these variable costs are much lower than if the activities in question were internalized. You can deploy technology services in minutes and go from idea to implementation orders of magnitude faster. This gives you the opportunity to experiment, test new ideas to differentiate customer experiences and scale your business.
Deploy globally in minutes
With the cloud, you can expand your business to new geographies and deploy internationally in minutes. AWS, for example, has an infrastructure all over the world. You can therefore deploy your application in different regions of the globe in just a few clicks. Bringing applications closer to end users reduces latency and improves their experience.
Types de cloud computing
The three main types of cloud computing are infrastructure as a service, platform as a service, and software as a service. Each type of cloud computing provides different levels of control, flexibility, and management, allowing you to select the right set of services to meet your needs.
Infrastructure as a Service (IaaS)
IaaS contains the building blocks for cloud computing. It generally offers access to network functionalities, computers (virtual or on dedicated hardware) and data storage space. It gives you the highest level of flexibility and management control over your IT resources. This is very similar to existing IT resources that many IT departments and developers are familiar with.
Platform as a Service (PaaS)
With PaaS, you no longer need to manage the underlying infrastructure (typically hardware and operating systems) and can focus on deploying and managing your applications. This makes you more efficient because you don't have to worry about resource provisioning, capacity planning, software maintenance, patching, or any other undifferentiated runtime overhead. of your app.
Software as a Service (SaaS)
SaaS offers an end product that is executed and managed by the service provider. In most cases, people who refer to SaaS services think of end-user applications (such as webmail). With a SaaS offering, you don't have to worry about managing the service or the underlying infrastructure. You just need to think about using this specific software.
