Clouds & Infrastructure Management

recently, someone asked me a question around infrastructure management – One of our business units are going in for cloud computing. Do they still have to look at infrastructure management?

 

here are my thoughts on the subject –

 

Typically infrastructure management involves design & planning of infrastructure components, procurement, deployment, operations and disposal. However, cloud computing introduces a different aspect – cloud management activities.

Cloud computing has various flavours like SaaS, PaaS, IaaS from services point of view. Also from ownership model, there are public clouds which are owned by service providers and then there are private clouds which offer cloud computing services but are owned by the customer themselves and reside in their data centers.

Depending on which service viewpoint and what ownership model is the customer considering cloud computing, there will be different levels of involvement in infrastructure management. Public cloud providers have solutions that involve a lot of automation thus making the infrastructure management activities simplified.

for public clouds

SaaS service does not require infrastructure management PaaS service does not require hardware level infrastructure management but will involve activities like provisioning and de-provisioning (cloud management activities), patch management etc.

IaaS service will require activities like provisioning, de-provisioning of compute resources, OS & application patch management etc.

for private clouds –

PaaS & IaaS will require infrastructure management like provisioning of hardware for setting up of private cloud and then cloud management activities like provisioning and de-provisioning of compute resources (cloud management activities), OS and platform patch management, incident, change, problem management etc.
