DevOps Engineer is a versatile soldier in the team of programmers: it will configure the application assembly, deploy the infrastructure in the cloud, make it scalable and repeatable. A good engineer helps a product move quickly (roll out a new version 10 times a day, for example) and when no one is in the way, optimize the infrastructure and company money.
As an example, we can tell the story of an engineer who in 2 months moved the entire infrastructure of an application with “artificial intelligence” to a new type of server. The new type of servers was with video cards, so specific calculations began to work out dozens of times faster, as a result – reducing the number of servers. The cost of infrastructure for business has decreased from $120000 to $200000, that is six times.
The second example – DevOps engineer came to the startup at the validation stage (validation – proof that the requirements of a particular user, product, service or system are met) hypothesis, the entire infrastructure – two servers, their programmers set up by hand. Suddenly, the startup shot, and the infrastructure failed – the old approaches in the style of “order a server, go to it, install the application” did not work under the load and pressure of users. The engineer decided to automate the creation of servers and move to a cheap cloud, finished just before Black Friday. The company continued to exist due to the fact that it managed to earn that day.
Entering the specialization is thorny and complicated: unfortunately, it is impossible to read the book “How to Learn DevOps in 21 days” and become a successful engineer. First, because such a book does not exist and cannot exist. Secondly, because DevOps-methodology is based on two specializations: programming and administration. This means that it is necessary to have a deep understanding of both fields at the same time.
Types of DevOps engineers
- Advanced programmers who had to configure the processes of building and deploying the application in different environments. The next step is that the programmer understands that he is interested in knowing how his application works in the real environment, and comes to the questions of how to scale and make it fail-safe. As a result he gets expertise at the junction of Dev and Ops.
- Advanced system administrators, who abandoned the usual “if it works – don’t touch” model, tried to automate routine activities and (most importantly) communicated with programmers. It is commonly believed that before DevOps-methodology there was a war between the operation and development departments. Because the business set different, conflicting goals and objectives for each department. And those who abandoned the usual model of interaction and began to understand how it works, together with programmers, also received expertise at the junction of Dev and Ops.
- Beginners who immediately jumped into DevOps specialization. These guys realized in time that the direction is popular and in demand, and studied immediately in the right vector. These guys have the least experience in IT, but as a result, their expertise is maximally tailored to the market. These are the most universal guys, who grew up on the right ground: they do not need to pull the luggage of old stereotypes, but often they lack the experience.
If your business needs a push for development, if you are interested in connecting new technologies, you should use devops service providers. If you choose the right company at this stage, you will have a real chance to get great help for your business. Devops can be an extremely useful option that you should design carefully and do whatever it takes to take it to the next level.
