Part 2 – Types of Cloud Computing & its adoption

Welcome back to the second part of our Cloud Computing Series. We shall know more about different types of clouds and its adoption.

Are you considering moving to the cloud? Well, doing things is more difficult than simply thinking about them. Moving to the cloud requires extensive planning and research. A step in the process is learning about the many kinds of cloud computing so you can decide which one to use.

So how many different kinds of clouds exist? There are three: Infrastructure as a Service (IaaS), Software as a Service (SaaS) and platform as a service (PaaS).

Infrastructure As A Service (IaaS):

IaaS cloud computing involves renting out on-demand web infrastructure to businesses on a pay-per-use basis. With IaaS, you don’t have to worry about the costs and complexities of buying and setting up your own hardware. The cloud provider takes care of all the infrastructure, such as servers, storage, and networking, and you can access and manage it remotely over the internet.

IaaS gives you the freedom to just pay for the resources you use, allowing you to maintain control over your IT infrastructure.

Software As A Service (SaaS):

In SaaS cloud computing, a supplier of cloud services hosts the software there and rents it to businesses for a set charge (either a one-time payment or a monthly subscription). As a result, the company’s IT departments are spared from having to install separate software on every computer. Instead, the information is accessible to all employees over the internet.

Think of it like streaming movies or music instead of buying DVDs or CDs. With SaaS, you don’t need to download or install software on your device. Instead, you can access the software through a web browser or a dedicated application, and use it directly from there.

You don’t have to worry about software updates or maintenance, as the service provider takes care of that for you. They handle things like security, backups, and infrastructure, so you can focus on using the software and getting your work done. Microsoft 365, Google Workspace, Amazon Web Services are some popular Saas provider platforms.

Platform As A service (PaaS):

In PaaS cloud computing, a cloud service provider leases out the infrastructure, development tools, and operating system that a company requires to create an application. The goal is to make the app development process simpler, especially if you want to improve processes in a setting where there are several developers working on the same project.

In simple terms, PaaS is like renting a fully equipped kitchen in a restaurant, where you can focus on cooking and creating delicious dishes without having to worry about setting up and maintaining the kitchen infrastructure. Microsoft Azure App Service, Google App Engine, AWS Elastic Beanstalk are a few examples of PaaS.

Software giants such as Microsoft, Google, Amazon  offer cloud computing hosting services, which can be either private or public clouds. Personal cloud services are only available to a small group of people or businesses. Public cloud services, on the other hand, are distributed freely throughout the internet to everyone. A hybrid cloud computing service is also available, and it is offered as both a private and public cloud service.

The adoption of cloud computing refers to the increasing trend of businesses and individuals using cloud-based services and technologies to store, manage, and access data and applications over the internet. The adoption of cloud computing has been driven by the desire for cost savings, flexibility, scalability, accessibility, and improved security. It has revolutionized the way businesses and individuals store, manage, and access their data and applications, making it an increasingly popular choice in today’s digital landscape.
