Why Cloud Pricing Comparisons Are So Hard

Public cloud computing companies all perform similar functions, so why is it so hard to compare the value of one cloud infrastructure service with another? There's a variety of reasons, but one of them is that vendors don't want you to be able to do too direct a comparison.

Each service supplier assembles a compute package that's different enough from the others that a comparison is difficult. Microsoft, for example, surpasses Amazon in CPU strength and storage. But in another important measure, Amazon offers more RAM for larger server sizes while matching Microsoft in the smaller sized servers.

Confused? The problem is there's no standard "serving size" when it comes to cloud computing, so IT pros have to juggle the many variables of RAM, local disk, CPU power, and more themselves. Is it a better deal to get lots of CPU but less RAM? The answer depends on what the cloud customer is trying to do with that computing power. For companies weighing public cloud options against running the computing services in-house, it complicates the calculation. Read More
