Cloud computing is the on-demand, charge distribution of IT services over the Internet. Instead of purchasing, operating, and maintaining physical data centres and servers, you may rent computing power, storage, and databases from a cloud provider like Amazon Web Services on an as-needed basis (AWS).
Data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web apps are just a few of the use cases that organisations of all types, sizes, and industries are embracing the cloud for. Healthcare organisations, for example, are utilising the cloud to produce more individualised treatments for patients. The cloud is being used by financial services businesses to power real-time fraud detection and prevention. The cloud is also being used by video game developers to deliver online games to millions of players all over the world.
The cloud gives you quick access to a wide range of technologies, allowing you to create more quickly and build almost anything you can dream. You may instantly spin up resources as needed, including computation, storage, and databases, as well as Internet of Things, machine learning, data lakes and analytics, and much more.
Technology services may be deployed in minutes, allowing you to go from concept to implementation several orders of magnitude faster than before. This offers you the freedom to try new things, explore new ideas, and alter your business.
You don't have to over-provision resources up front with cloud computing to manage future peak levels of company activity. Instead, you allocate the exact quantity of resources that you require. As your business needs change, you can scale these resources up or down to immediately expand and shrink capacity.
The cloud enables you to swap fixed costs (such as data centres and physical servers) for variable costs, allowing you to pay for IT just as you need it. Furthermore, due of economies of scale, the variable charges are significantly lower than what you would spend if you did it yourself.
With the cloud, you can extend to new geographic locations and deploy internationally in minutes. For example, AWS has infrastructure all around the world, so you can deploy your application in numerous physical locations with just a few clicks. Bringing applications closer to end consumers lowers latency and improves the user experience.
Infrastructure as a Service, Platform as a Service, and Software as a Service are the three basic categories of cloud computing. Each type of cloud computing offers varying degrees of control, flexibility, and management, allowing you to choose the best collection of services for your needs.
IaaS contains the essential building elements for cloud IT. It usually gives users access to networking capabilities, computers (virtual or dedicated hardware), and data storage. IaaS allows you to have the most freedom and control over your IT resources. It's very comparable to existing IT resources that many IT departments and developers are already familiar with.
PaaS relieves you of the burden of managing underlying infrastructure (most commonly hardware and operating systems), allowing you to concentrate on the deployment and administration of your apps. This allows you to be more productive because you won't have to worry with resource procurement, capacity planning, software maintenance, patching, or any other undifferentiated heavy lifting that comes with running your application.
SaaS gives you a fully functional product that is managed and maintained by the service provider. Most of the time, when people talk about SaaS, they're talking about end-user applications (such as web-based email). You don't have to worry about how the service is maintained or how the underlying infrastructure is managed when you use a SaaS provider. All you have to do now is consider how you'll use the software.
