You don’t need any fancy tools for that, no Jenkins, no fancy programming framework, not even Git. Again these are to understand the basic concepts and then you can start learning those DevOps tools like Jenkins, Docker, Kubernetes and so on. Because this phase is not about learning the tools, it’s about understanding the concepts and the complete workflow. This means before you automate processes and tasks that are done manually, you first need to understand what those processes and tasks are in the first place. If you don’t understand those, you won’t know what you’re automating or why you even need DevOps.
Programming, coding, and scripting are most relevant for the role of a DevOps Engineer or a Site Reliability Engineer (SRE) within a DevOps team. These roles typically involve automating and streamlining software development processes, such as building, testing, and deploying software. They often use scripting languages, such as Python or Bash, to write scripts that can perform tasks such as creating and managing virtual machines, provisioning infrastructure, and automating testing and deployment. This allows them to automate repetitive tasks, increase efficiency, and reduce the potential for human error. Additionally, they may use programming languages like GoLang or Java to develop custom tools to support their workflows. DevOps engineers and SREs are responsible for the design, implementation, and maintenance of the infrastructure and tools used to support software development and deployment.
Practice while you learn with exercise files
Regulated industries are often mandated to provide a certain level of observability, traceability and access of how features are delivered and managed in their runtime operational environment. This requires planning, development, testing, and enforcement of policies in the continuous delivery pipeline and in the runtime environment. Auditability of compliance measures is extremely important for proving compliance to 3rd party auditors. Solution delivery and delivery pipelines are essential to a good DevOps background. In my experience, most developers are really good at utilizing their ecosystems to compile a binary or build out a package. Software developers should be familiar with the basic fundamentals of a data center or cloud depending on where your solution(s) is/are hosted.
Utilizing code to quickly evaluate, split, transform, or compare lists is a great place to start off since every company has data that needs something done with it. From there, you can choose to grow your skills organically or strategically depending on your affinity for writing code. A software developer who is familiar with one or more programming languages does not need to be intimately familiar with every intricate detail of a backup https://remotemode.net/ solution but should know how to retrieve and restore backups when necessary. Since I started to learn Docker, during writing any dockerfile I felt like I am doing something that was not a typical developer or devops job; It was something between. While knowing how to run a website using nginx or apache is typical devops, the contenerization aspect feels not as its Software architecture as code and this is relatively new for me.
Why do Site Reliability Engineers Need a Coding Background?
Moreover, complaints can come through dozens of channels – CloudFlare, domain registrars, site feedback, infrastructure providers, and many others. The Atlassian OpsGenie application is very helpful in notifying the on-call about accidents. Worse, it starts escalating all incidents to the next employee on the list if the previous on-call didn’t take them on. One of the most traditional topics nowadays is the unexpected career shifts from various professions to IT and vice versa. He sets up monitoring systems like a pro and can defend his point of view convincingly.
Some examples would be writing a shell script to do a task in a Jenkins job in a CI/CD pipeline or writing a small utility script for flushing the cache, starting the builds and deployments, connecting different tools etc. Now here it’s important to mention that you don’t need to be a software developer or the one implementing those agile and scrum processes. You need to understand how those things work on a high level, conceptually. When put in the context of agile development, the shared accountability and collaboration are the bedrock of having a shared product focus that has a valuable outcome. I firmly believe that everyone should pick up at least one programming language that they can become proficient with.
Monitoring crashes louder than usual
Take a step back and ask yourself how you can use business logic to generate your infrastructure, monitoring, configurations, backups solutions, automated testing, etc. This approach will make something that feels unmanageable and makes it manageable again. Once you have mastered the above skills and technologies it’s time to learn how to optimize and automate the existing processes. And as a DevOps professional automation skills are one of the most important ones. Some network engineers even know scripting in bash or python for example, which is another helpful skill when it comes to automation part of DevOps.
So you have valuable knowledge in configuring networking for infrastructure on premise. The last honorable mention of a background going into DevOps is network engineering. This is probably the farthest from DevOps compared to the other three that I just mentioned, but you still have some skills that you can bring into DevOps as a network engineer. There are many programming languages, but I would recommend starting with Python.
In my last system administration role, starting at a new company, I found a bit of a mess. Servers were manually configured, there was almost no deployment automation or validations fo successful deployments, and there was broad access around the organization directly to production servers and databases. DevOps is all about automating the flow of delivery through resilient pipelines to increase quality.
In DevSecOps, security is a “first class” citizen and stakeholder along with development and Operations, and brings security into the development process with a product focus. A system administrator does not need to dive deeply into SQL query optimization, but knowing how to write and retrieve data from the database is a useful skill to help support the team. Now I am touching Docker Swarm (I kind of failed at learning Kubernetes when it came to storage types, so I feel like starting from Swarm is a better way).
