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.

While the overall numbers are not necessarily sexy, the percentage growth surely is. If you are looking for a tool to search and analyze data, Elastic stack and Splunk are showing exponential gains in the last couple of years. Therefore, if you are currently a DevOps engineer or looking to take your career in that direction, it is essential that you familiarize yourself with the Elastic stack or Splunk.

In order to analyze the Elastic stack, we broke it down into its main three components: Elasticsearch, Logstash, and Kibana. While all three separately have grown over 40% over the course of the last year, it is essential to put the trio together to get the full extent of their growth trajectory. In that case, we have seen a growth rate that has exceeded 150% since the latter part of 2015. Truly remarkable.

Linux certifications on demand

In continuing our evaluation of data from our skills watch, the next area of exploration is certifications. Much has been written over the years about the positives associated with obtaining a certification, and the effects it has on ones career trajectory. With that being said, the most important piece of the equation is whether or not corporations are putting the same value on that certification. Beside a desire for knowledge, one wants to know if that accreditation will result in a positive return on investment. After all, a lot of the certifications in existence do not come cheap.

In a nutshell, the data shows that in fact there is not an increase in postings requiring certifications over the last couple of years. As one can see below, if it were graphed, it would be a little bit of a roller coaster ride. But, if anything, there appears to be less demand for most certifications as time goes on. It almost appears to be a feat of strength if a certain certification can just maintain the level of interest over the years:
