From Zero to DevOps Engineer DevOps Roadmap for YOUR specific background DEV Community

Next I brought in Ansible to work as an orchestration engine across the ecosystem. For now I managed to setup a good Jenkins pipeline using nested containers https://remotemode.net/ across many nodes, it was not that hard except few docker quirks. Nasty Asian bots trying to clone content and parasitize on the client’s resources.

  • However, it’s worth noting that as the field of DevOps continues to evolve, the use of automation and coding will become more prevalent.
  • Organizations can also find some common ground to reduce extraneous costs on their products as well.
  • 2.2 – Containers with Docker
    And as part of the more modern infrastructure concepts you need to understand how to work with containers and the most popular container technology, which is Docker.
  • As volumes grew, we decided to move to more advanced automatic processing of screenshots with rejection, cropping, and sharpening on GPUs with neural networks.
  • DevOps had managed to achieve a grassroots following that was starting to put their ideas to use.

By packaging and permanently fixing all OS dependencies, containers enable rapid CI/CD and deployment cycles, because all integration, testing and deployment occurs in the same environment. And Kubernetes orchestration performs the same continuous configuration tasks for containerized applications as Ansible, Puppet and Chef perform for non-containerized applications. For example, developing and updating microservices – that is, the iterative delivery of small units of code to a small code base – is a perfect fit for DevOps rapid release and management cycles.

Do most of devops people have a background in being a developer?

New pieces of technology arise from time to time that drastically change the way the world functions. More recently, technological advancements seem to have begun to appear at a blistering pace. Ever since the advent of the internet, the spread of information and the rate of development of new technologies has only increased. DEV Community — A constructive and inclusive social network for software developers. And since most of the modern applications and Kubernetes clusters are running on cloud, you need to learn cloud infrastructure, how to work with cloud infrastructure, how to configure it, how to scale it and so on.

To do this, most of your work is going to be through scripts or tools like Chef, Terraform, Puppet, CloudFormation, etc. Composing individual scripts for individual tasks is a good place to start, but will quickly become overwhelming if you are not embracing a more generated approach. If DevOps had a birth certificate, the father’s name would be penned in as Patrick Debois.

Starting as a Software Developer 👩‍💻

Decorated half your house with humidity sensors, temperature gauges, and other automation, aggregating all logs? Analyzed large volumes of raw data for hidden correlations in the scientific field? All my colleagues are amazing, talented people with the most diverse backgrounds and hobbies. The main thing is that work tasks feel like the next challenge and make your eyes shine. After years of such experiences, we’ve shifted to a zero-trust concept towards service providers. The service must continue to work despite the banning of domain names in CloudFlare, IP address blockades, full lockdown of rented capacities, and other actions by providers.

As soon as the binary stopped, all metrics screamed of a sudden drop in load, as it turned out, it managed all the advertising traffic on some platform. For instance, I had a task involving the bootstrap of physical servers serving as content distribution points. Each node group contains several hundred thousand files, actively distributed and cached via CDN. The problem arises when there’s a sudden acute shortage of capacities, and we need to add another server to the group.

Why the History of DevOps Matters

The industry is, on one hand, extremely conservative with old but reliable PHP code at the core of the system. On the other, it can be tightly integrated with a modern stack and constantly changing requirements. In reality, one of the probe nodes, which checks the HTTP endpoints’ operability, simply lost connectivity and cheerfully sent a batch of messages to Datadog, claiming several data centers with hundreds of endpoints had vanished. Monitoring there is specific, with alerts for each of the hundreds of existing connections. Human skills like collaboration and creativity are just as vital for DevOps success as technical expertise.

And it would be difficult to deal with the complexity of a microservices architecture without DevOps deployment and operation. The primary driver behind configuration management is trying to hit the gold standard of immutable infrastructure. While application code is being perpetually updated and changed, servers should be treated like cattle instead of pets. We should be able to easily destroy and fully rebuild a server and deploy the newest version of the application on top of it. Aside from SFTPing that package out to a server and bouncing a service the idea of automated blue/green solution delivery flow with configuration management, rollbacks, database updates, monitoring changes, etc. is not the norm.
