It puts small teams with varying objectives together to work toward more efficient and high-quality code releases. There cannot be any barriers between the different personas, making communication skills (both verbal and written) a necessity for a successful DevOps engineer. More concretely, the DevOps engineer’s goal is to improve multiple facets of the software development life cycle (SDLC) process using a mix of practices, tools, and technologies. A devops engineer is involved in the planning and coding phase of software development, where they help define the requirements, design the architecture, and write the code.
Instead of doing CM, cloud providers allow you to provide user metadata scripts that can run when you create a server. While understanding CM is essential and you will use it from time to time, it is best to design your architecture in such a way that you can avoid it as much as possible. This is because no matter how well you do CM, there will always be a configuration drift after a period of time.
- In DevOps, the top priority is to deliver high-value features in short periods of time through cross-team collaboration.
- However, you need to at least know basic programming concepts, such as loops, variables, arrays, lists, etc.
- While understanding CM is essential and you will use it from time to time, it is best to design your architecture in such a way that you can avoid it as much as possible.
- The people who benefit most from DevOps certificates are the vendors that want you to believe you need them.
Simply dragging a monolithic application from a server and dumping it on a container will not make it a microservice. Instead, each component needs to be split and redesigned to account for extra latency, connectivity, and also segregate data and config layers from the running application. Monoliths devops engineer how to become are simpler to get started with and operate and you don’t need to deal with issues such as latency or connectivity nearly as much because everything is likely to reside in one place. However this simplicity also makes them tightly coupled, less scalable and harder to upgrade without downtime.

Organizations rely on their DevOps engineers for guidance and leadership across their entire app development lifecycle. Because of this, DevOps engineers are often some of the most seasoned professionals in their organization and it can take many years for DevOps engineers to acquire all the skills they need to be successful. Other duties of a DevOps engineer may include coding, automation, security, and infrastructure management.

In addition, since DevOps is all about CI/CD, you must confidently manage complex automated delivery pipeline phases through Jenkins and/or other servers. This requires discipline, attention to detail and an end-to-end understanding as you automate processes or enter code changes into the pipeline. DevOps engineers rely heavily on automated tools and processes to manage their workflows.

Containers are often used a lot in CI/CD pipelines, as well as in production workloads and microservice architectures, so understanding containers is a must. Container orchestrators are also used a lot these days which we will explore later. I recommend you learn the basics and start with Python as it is easy, then do lots of challenges in a website like Edabit and work your way up to intermediate. If you get to that level, you shouldn’t have a huge issue scripting and doing most automation jobs that come your way.
DevOps engineers, categorized under software developers and similar roles by the U.S. Bureau of Labor Statistics, are expected to see a 25 percent growth in open jobs by 2031. DevOps engineers specialize in development and operations processes to coordinate efficient product development for a company. DevOps engineers also oversee the activities and needs of a software product’s creation from planning to deployment.
Git is a distributed version control system for tracking your code changes that is widely used by all software engineering and operations teams. I strongly recommend you spend some time familiarising yourself with it and the concept of branches, rebase, merging, etc. Another way to gain DevOps skills and understand the DevOps process is by participating in CompTIA training. CompTIA offers many training options that cater to every learning style and need. Through CompTIA training, IT pros who want to work in DevOps will not only gain critical DevOps skills, but they will also be fully prepared for their CompTIA certification exam.
