Cloud Service Models in cloud computing

Dear DBA-Mates,

As per last commitment/promises, we are back with next topic Cloud Service Models.

Here, we would like to explain it in simple and short notes for quick references. This is one of the basic and important which should be clear for any cloud concepts. So, tried to clear in simple ways, hope this will be useful for all.

Cloud Service Models: Means the Services provided by the Cloud companies.

Please find the below main Cloud Service Models:

1. IaaS: Infrastructure as a service

In this Service model, we will get infrastructure template by cloud provider company and remaining management, configuration part will be taken care by the clients.

Eg. in aws: EC2 -- virtual machine (only this will be provided by Cloud provider with resources as per demand)

We Manage: Data, Apps, Runtime, Middleware, O/S. (Total is 5)

Provider Manage: Virtualization, Server, Storage, Networking. (Total is 4)

2. PaaS: Platform as a Service

In this Service model, Cloud provider company will provide configured platform and client only need to deploy their apps, codes etc…

We Manage: Data, Apps (total is 2)

Provider Manage: Runtime, Middleware, O/S, Virtualization, Server, Storage, Networking. (Total is 7)

3. SaaS: Software as a Service

In this Service model, Cloud service provider company will provide direct software to use. Client/user will use direct software through internet from anywhere in the world.

In Shorts:

Ready to use software. -- We will only login on internet and will use apps.

Example: Gmail, Facebook etc... web software, web services in software form.
