Every day hundreds of millions of dollars are wasted by allowing improperly tuned or misconfigured systems, misunderstood infrastructure, and inefficient IT operations to live and thrive in data centers around the globe. There are both direct and indirect costs associated with allowing these unhealthy systems to continue to exist. Let’s look at some.
Let us start by using a small example. We will start by looking at a small database setup. This setup will have a single master-slave, with a database size of lets say 500GB. Traffic is steady and let’s say this translates into 500 IOPS on the master. You have chosen to host this on Amazon’s AWS. A common way of ensuring backups occur in AWS is to setup ebs snapshots of the slave. In terms of usage, let us assume your CPU is about 50% used and you have about 20GB of hot data that needs to stay in the memory for the database.
If we look at what this …[Read more]
