Why use provisioned IOPS volumes for AWS databases?

In this blog, we’ll use some test results to look at the rationale for using provisioned IOPS volumes for AWS databases.

One piece of advice you often hear running MySQL, MongoDB or other databases in the AWS EC2 environment is that you should use volumes with provisioned IOPs. This kind of makes sense on the “marketing” level, where provisioned IOPS (io1) volumes are designed for IO-intensive database workloads, while General Purpose (gp2) volumes are not. But if you go to the AWS volume type description, you will find that gp2s are shown to have pretty good IO performance. So where do all these supposed database performance problems for Amazon Elastic Block Store (EBS), with no provisioned IOs, come from?

Here is what I found out running experiments with a beta of …

MongoDB Administration Checklist for MySQL DBAs

In this blog, I discuss a MongoDB administration checklist designed to help MySQL DBAs.

If you are MySQL DBA, starting MongoDB administration is not always an easy transition. Although most of the concepts and even implementation are similar, the commands are different. The following table outlines the typical MySQL concepts and DBA tasks (on the left) to corresponding MongoDB ones (on the right). If you happen to be a MongoDB DBA and want to learn MySQL administration, you can use the same table looking from right to left.

I’ve also created a webinar, MongoDB administration for MySQL DBA, that explains the above concepts. You can download the slides to use as a reference.

The Holy Grail Webinar: Become a MySQL DBA - Database Performance Tuning

You’re running MySQL as backend database, how do you tune it to make best use of the hardware? How do you optimize the Operating System? How do you best configure MySQL for a specific database workload?

Do these questions sound familiar to you? Maybe you’re having to deal with that type of situation yourself?

A database server needs CPU, memory, disk and network in order to function. Understanding these resources is important for a DBA, as any resource that is weak or overloaded can become a limiting factor and cause the database server to perform poorly. A main task of the DBA is to tune operating system and database configurations and avoid overutilization or underutilization of the available resources.

In this webinar, we’ll discuss some of the settings that are most often tweaked and which can bring you significant improvement in the performance of your MySQL database. We will also cover some of the variables …

Shinguz: MySQL spatial functionality - points of interest around me
