The Global DevOps Market is expected to surpass $20 billion by 2026.

It is continuously evolving to meet the changing demands of the corporate environment.

Here are 7 basic concepts you must master to excel as a DevOps Engineer:

1. Intermediate to advanced Linux skills:

In DevOps, you’re not installing a server once and then logging in every now and then to perform a few admin tasks. You need to understand how to create highly customized Linux images from the ground up both for VM & container use cases.

2. Intermediate networking skills:

Networks are part of infrastructure as code. At a bare minimum, you’ll need a solid grasp of the OSI model, IPV4, subnetting, static and stateful firewalling and DNS.

3. A commitment to at least one cloud:

Clouds aren’t merely managed data centers. In order for you to automate workloads in a given cloud (AWS, Azure, GCP, etc.), you need a firm grasp of their specific semantics.

4. Infrastructure automation:

Once you understand the resources (and their properties) applicable to a cloud, you’re ready to automate their creation using tools such as Terraform and Ansible.

5. SDLC, CI/CD pipelines, and scripting:

In DevOps, we deliver an infra layer similar to applications. So you’ll need to be acquainted with the fundamentals of the software development life cycle (SDLC). It includes versioning using Git and CI/CD pipelines.

6. Container technology:

For legacy workloads, you may automate the creation of a VM image. But for new applications, you’ll be working with containers. As such, you need to know how to build your own Docker images (Linux skills required!) and deploy them using Kubernetes.

7. Observability technology:

While all clouds have monitoring dashboards and standard “telemetry” hooks, most large employers use third party (both commercial and open source) monitoring tools such as Prometheus, DynaTrace, Datadog, or the ELK stack.
