Understanding SaaS

SaaS, or cloud application services, are services where most of the heavy lifting is done by the cloud provider (in this case, AWS). In this case, you will not have to install software or worry about the operating system or software patches. Your focus will be on customizing the business logic of your application and supporting your users. SaaS applications usually have light resource requirements on the client side. For example, a browser or a lightweight IoT device. Most of the heavy lifting and computation gets done on servers in the cloud.

In terms of software installation, SaaS gets rid of the need for your staff to visit individuals' devices. AWS is fully responsible for any issues that might arise on the server, middleware, operating system, and storage levels.

Let's now analyze the characteristics that make up SaaS, the advantages and disadvantages of using a SaaS deployment, and some SaaS examples.
