Over the years, a myriad of web servers have been written. Apache, being one of the oldest, is the most widely used today. However, it was implemented with a scaling mechanism that can be relatively inefficient in some ways. Some newer web servers have come out in the last few years that attempt to address some of the shortcomings of Apache. One of the most prominent of these is Nginx. Both Apache
NoSQL Comparison Benchmarks | DataStax
NoSQL databases are challenging relational technologies by delivering the flexibility required of modern applications. But, which NoSQL database is best architected to handle performance demands of today’s workloads?

You Should Use EBS Boot Instances on Amazon EC2 · Alestic.com - A Personal AWS Blog by Eric Hammond
EBS boot vs. instance-store If you are just getting started with Amazon EC2, then use EBS boot instances and stop reading this article. Forget that you ever heard about instance-store and accept my apology that I just mentioned it. Once you are completely comfortable with using EBS boot instances on EC2, you may (or may not) want to come back here and read why you made a good decision. EC2 experts
