AWS and Rackspace are both giants of the cloud infrastructure services arena. Although to paraphrase George Orwell’s famous novella, all cloud providers are not created equal. So let’s take a closer look at our pugilists before placing bets or declaring the winner. The Contenders
MySQL and PostgreSQL are two of the most popular open-source RDMS (Relation Database Management System) programs on the market. They have competed favorably with commercial closed-source database programs for many years. Each has developed a reputation for specific strengths and weaknesses. MySQL is perceived to be much quicker but offers fewer features. PostgreSQL is believed to have a deeper feature set. Some programmers think of PostgreSQL as being similar to Oracle, and it is often favored by those who know Oracle products.
Shipping Containers and Compute? LXC (LinuX Containers) is a OS-level virtualization technology that allows creation and running of multiple isolated Linux virtual environments (VE) on a single control host. These isolation levels or containers can be used to either sandbox specific applications, or to emulate an entirely new host. LXC uses Linux’s cgroups functionality, which was introduced in version 2.6.24 to allow the host CPU to better partition memory allocation into isolation levels called namespaces . Note that a VE is distinct from a virtual machine (VM), as we will see below.
