Episode 57 – Should I adopt Infrastructure as a Service?

Your computers don’t have to be located in your own server closet.  You can move them to the cloud.  So, should my firm adopt infrastructure as a service?

Infrastructure-as-a-Service, often abbreviated IaaS, is a pretty well established model.  Instead of buying your own computer in your own building, you simply rent one and access it over the web.

When deciding whether to adopt such a business application, you’ll probably consider the total cost of ownership, flexibility, and security.

When you add up the cost of renting a server in the cloud, you’ll likely find that you could have bought your own server for the amount you’ll pay after some number of months.  As you add in overhead and various soft costs, you’ll get a clearer picture of your total cost of ownership.  You may well find that it is cheaper to choose IaaS instead of purchasing and maintaining your own equipment.

If your business is seasonal or the number of customers varies, you may find that it makes more sense to choose IaaS.  You can adjust your number of servers up or down to match demand.  You can’t do this when you purchase machines outright.

Security evokes great debate in this model.  IaaS operates under a shared responsibility model.  The service provider ensures the physical security of the box.  They ensure the network leading to the equipment is secure and they typically let you filter traffic that can reach your machine.

Beyond that, you own it all.  You secure the software, the users, the data.  You monitor it for intrusion.

Tomorrow, we take a deeper look at the security implications of the shared responsibility model.
