Question
A reputed IT company avails a cloud service that provides the infrastructure resources such as servers, storage, networking, etc. The company uses the infrastructure to deploy an application which was developed using a PaaS. Who would be responsible for the maintenance of the infrastructure resources and the application?
Solution
In a cloud service model, the responsibility of maintenance is divided between the service provider and the client based on the type of service availed.
-
Infrastructure as a Service (IaaS): In this case, the cloud service provider is responsible for maintaining the infrastructure resources such as servers, storage, and networking. The IT company using the service would only be responsible for managing the applications, data, runtime, middleware, and operating systems.
-
Platform as a Service (PaaS): Here, the cloud service provider manages the servers, storage, networking, operating system, and also the middleware. The client company is only responsible for the applications and the data.
So, in the given scenario, the maintenance of the infrastructure resources (servers, storage, networking, etc.) would be the responsibility of the cloud service provider. Since the application was developed using a PaaS, the maintenance of the application would be the responsibility of the IT company.
