The consideration behind this approach was that a job posting and description provided quite an authoritative statement of a company's intentions on DevOps, i.e. they are literally putting their money on it.
OBSERVATION #1: Start
ups are hiring DevOps engineers at almost twice the rate of established enterprise
companies. Is this a clear indication that DevOps’ is more prevalent in start up cultures? Welcome your input and anecdotes.
Locations that had only one
posting were included under "Other". Clearly DevOps is a national and global phenomena. What factors do you think are at play in the numbers above?
We will post additional observations in subsequent postings on other variables such as application type, cloud environment used, tool chain, on-call requirement etc. Your input and observations are welcome.
About the survey:
- This is not a scientific survey. Sample size was 51 open job postings collected from various job sites in early April 2012.
- 30+ parameters were analyzed and they fell into categories such as company information, responsibilities, skills needed and tools used
- Only one DevOps job posting per company was considered
- Some postings were discarded because it was not possible to establish key information such as company size, location etc. Postings by job agencies were also discarded.
- This survey reduces “Measurement Error” - biases caused due to leading questions and due to social desirability, which occurs when respondents feel pressured to answer questions a certain way in order to fit into a club, in this case the super cool DevOps club!
- However, this survey is not without bias. It has 'Sampling errors' since participation was limited to companies that posted a job, some 'Measurement error' is possible because the job poster may have missed listing all job requirements in the job description.
