Infrastructure a service

Posted on 2011-10-13

I have read the definition on the internet
"Infrastructure as a Service is a provision model in which an organization outsources the equipment used to support operations, including storage, hardware, servers and networking components. The service provider owns the equipment and is responsible for housing, running and maintaining it. The client typically pays on a per-use basis."

Just want to know what are the storage,hardware, servers and networking components that will be outsourced.

          You are outsourcing as much as or as little as you and your service provider agree can be nearly everything except for the client end user machines, or it could only be a portion of your IT services (like your content servers) which would be utilized on a pay as you go basis; hope this helps!

    I believe that it would be, as long as the service provider maintains control of the equipment (routets, switches, power supplys, etc) You could use VM to access your services in the provider managed infrastructure.

    Storage As-A Service (SAAS - Provide storage on demand
    Network as a Service (NaaS) - Provide Network Infrastructure on demand
    Security-as-a-service (SaaS) - outsourcing model for security management

    Hi Karan,

    IaaS could be used to define your scenario and it is also synonymous with using a managed service provider - alot of the terminology has changed to 'cloud' speak but underlying physical mechanisms remain the same
