Is EC2 software as a service?
No, Amazon EC2 is considered Infrastructure as a Service (IaaS), not Software as a Service (SaaS).
The key difference lies in the level of responsibility and management required from the user. With IaaS like EC2:
- Amazon manages the underlying infrastructure - networking, storage, servers, virtualization
- Users are responsible for managing the operating system, middleware, runtimes, data, and applications
Whereas with SaaS:
- The SaaS provider manages everything - infrastructure, operating system, runtimes, data, and application
- Users only need to access the application through an interface like a web browser or mobile app
So in summary:
- IaaS (EC2) - Amazon manages infrastructure, users manage OS and up
- SaaS - Provider manages infrastructure + OS + runtimes + data + application. Users only use the application.
As an IaaS, EC2 provides users more control and flexibility with infrastructure configuration since they handle OS, middleware etc. SaaS is more turnkey but less customizable since the provider controls everything behind the scenes.
Both service models have their place depending on application architecture needs and the level of management desired by customers. But EC2 itself is not SaaS since users must still install, configure and manage platforms and software.
What are PaaS services in AWS?
Platform as a Service (PaaS) refers to a pre-packaged combination of cloud computing hardware and software tools that let you develop and deploy applications with ease. AWS offers several PaaS services that provide developers with ready-made environments for building and hosting applications without having to manage the underlying infrastructure.
