Many people would like to read your FLOSS story on LinuxCareer.com
A microcosm of today's world includes building cars via robots, self driving vehicles, etc. No matter the task, it appears the number one goal is to automate it as much as possible. The technology landscape is no different. DevOps engineers are asked to automate as many tasks as possible in the current environment. This benefits both the engineer and the corporation. As an engineer, there are a lot of choices to complete a particular task at your disposal, but which automation tools are leading the way?

Probably not surprising, Puppet and Chef tend to garner the largest overall numbers. That has been the case when the data was originally analyzed, and it continues to this day. However, the more important piece is, are they growing? In both cases, the answer is no. Puppet has seen a decline of nearly 10% over the last six quarters, while Chef has seen an increase of about 7% over that same time period. In a nutshell, they both garner large demand, but they have remained fairly stagnant.

Wow has it been a whirlwind over the last ten years in the virtualization space. Where once Xen and then KVM sat on the pedestal, the baton has been passed to the projects revolved around containers. Names like Docker, Kubernetes and Mesos are most often mentioned. As is generally the case in the FLOSS arena, evolution is a constant. Therefore, if one is in the DevOps arena, it is time to familiarize yourself with containers if you have not already done so.

First of all, let's examine the virtual machine space. VMware, the elephant in the room, still commands a lot of attention. After all, it is a publicly traded company with billions in revenue. A lot of companies utilize VMware for its virtualization needs, and the numbers bear that out. Essentially, it is still the leader in the clubhouse. But, its lead is not what it once was. Over the 15 months examined, whether it is VMware, ESX/ESXi or vSphere, all have been on the decline. Each of those keywords within the listings has seen a 20-30% slide. And, more concerning is the fact that they have been falling at a fairly even pace.

In an ever-changing world, the data surrounding relational and non-relational databases is no different. While there are proponents for both, it seems to be a case by case basis for which is best for a particular environment. And, with the pace of innovation, the answer can be swayed on a frequent basis. With all that being said, the numbers don't lie, and there is evidence of a shift that is occurring.

While most of the stalwart SQL related databases (MSSQL, Oracle RDBMS, DB2, etc.) remain stagnant, there has been a decline in interest for MySQL. Might seem surprising given the fact that one of the core components of the original LAMP stack is losing ground. How could that be the case? In essence, a lot has changed since it came into prominence. Most importantly, in my opinion, is that it was purchased by Oracle. No longer an independent entity, you have one company controlling two prominent database choices. Is it possible for Oracle to be unbiased and treat each on its own merits? Perhaps. Only the folks inside the company know the true answer to that. Whatever the answer may be, it goes without question that the momentum that MySQL once had has been subdued.
