As Alexander Haislip, writer for Tech Crunch, starts his informative article “Sins of Cloud,” he provides a great introduction comparing Cloud to the Creation of the World and that it was intended for good, but cautions users to watch out for pit falls which can add costs. The first is use only what you need and turn it off when finished. Giving the example that “instances of machines often run idle between 15% and 40% of the time. “ Next is adding services like updating patches. At $100 per month and $0.12 hour it can add up and suggests doing it in house to save money. He ended stating that sometimes you need to leave the cloud if it’s a better fit for your company.
After reading this article I had a few questions. What are EC2 and micro instances? EC2 is one of many Amazon services called Elastic Compute Cloud. Basically you rent computing time and space. Amazon has different types of usage from micro to standard small to standard extra large. These types are called instances. Each with a different memory capacity and various other components of computer usage such as 32- or 64- bit platforms and I/O performance.
Basically every IT person needs to be aware of the computing needs and usages for their company. It is really good information. I will definitely beware of these pitfalls if I ever use Cloud computing.
