DevOps Emergence and a rise in demand for DevOps Engineers
After a conference in 1968, the term Software Development became known. Various IT moguls and software experts met to discuss the difficulties and pitfalls of designing complex systems. As a result of this meeting, a definite search for the solution began. Evidently, the focus was on finding a scheme or a philosophy that concentrates both on methodologies and tools.
Problems with the Earlier Software Development model (Before DevOps)
The earlier software development models –
- Led one to expect to support continuous feedback
- Accommodate changes in software requirements throughout the software development life cycle, and
- Support close collaboration between customers and developers.
However, it was not always a systematic process starting from the building of the code to its deployment and accommodation of changes in software requirements throughout the software development life cycle as it was never an easy task. The Dev team and Ops team were separated by a wall in a company’s office. Often, the Dev team would work on a single version for 6-10 months and then throw the code over the wall to the operations team, saying “We’re done! You can make it run.”
Ops team would then spend a couple of weeks trying to make it a run. Meanwhile, the Dev team will go back to the software and start working on version 2.0. After the Dev team finished, they would throw the code over the wall again, not caring what happened to the v1.0 and the Ops would feel anxious thinking “we built the operations side with some assumptions around what we saw in v1.0 and v2.0 breaks everything. We’d have to start all over again!”
With the old models, the Dev team did not care about what happens to the Ops team- “You make it run!”
The Ops team would get irritated – “We made it run, do not break it” or “Your code is faulty, it doesn’t run”
DevOps to Rescue!
This is when DevOps emerged, back in 2009!
DevOps is a culture that sets up a new level for better communication standards between the Dev team and the Ops team. As a result, it allows this wall to be torn apart. Dev should understand the operations side of things and the Ops team should understand what is happening on the Dev side. The two can work in collaboration to make things work smoothly. With that being said, most companies use the DevOps model to convert the code into a revenue-generating product. As with shorter release cycles, it is easier to receive logs, error feedback and minor bug fixation errors from the monitoring tools. This helps in the continuous delivery of the product with maximum quality assurance!
Who is a DevOps Engineer?
DevOps engineer is a person who –
- Understands the entire SDLC
- Has gained an understanding of various automation testing tools for developing CI/CD pipelines.
Evidently, DevOps means building digital pipelines that take code from a developer’s laptop to the operations guy’s laptop and result in a revenue-generating product!
The percentage of companies investing in DevOps rose from an already-impressive 66% in 2015 to 74% in 2016. Also, tools like Chef, Puppet, and Docker are home to massive user bases. Hence, the demand for skilled DevOps engineers is also on the rise.
As many firms institute DevOps practices, it’ll become even more necessary for their competitors to institute similar (or ideally, better) practices. The ratcheting impact could probably push demand forward indefinitely.
Corporations have an interest in DevOps, and it looks unlikely that the trend will reverse itself anytime soon. In terms of job demand, the market is usually oversaturated, although with a fall in salary averages. This leads to the demand of a DevOps engineer to accumulate a vast range of roles and responsibilities under his cape. Now that you know who is a DevOps Engineer, let us look at some of the fine, specific and trendy DevOps Engineer roles and responsibilities.
DevOps Engineer Roles and Responsibilities
DevOps Engineering is indeed a role that emerged during the renaissance. We can call a person with Cloud Foundation Information Technology services as a DevOps Engineer. Often, it is difficult to understand this role. The reason being – DevOps Engineer is the product of a dynamic workforce that has not yet finished evolving. Now, keeping in mind the needs and requirements of companies practicing DevOps, here are some of the DevOps Engineer roles and responsibilities:
DevOps Engineer roles and responsibilities:
- Hands-on experience with Cassandra, Elasticsearch, and MySQL.
- Linux server administration experience or a deep understanding of Linux/Unix
- Hands-on experience using Puppet, or Chef, or any other configuration management tool.
- Prototype, develop and apply software integrations based on user feedback.
- Implement automation tools and frameworks (CI/CD pipelines).
- Analyze code and communicate detailed reviews to development teams to ensure a marked improvement and timely completion of projects.
- Implement cloud (AWS, Azure, GCP) computing ability to deploy upgrades and fixes.
- Able to carry out approaches such as risk-management, clustering, load balancing, and failover.
- Conduct system tests for security, performance, and availability.
- Good interpersonal and communication skills.
Now that you know the various DevOps Engineer roles and responsibilities, let us look at the key skills of a DevOps Engineer.
After analyzing some top companies’ roles and responsibilities, we have collated a subset of the skills they look for in a DevOps Engineer:
