What do you need to become a DevOps engineer?
Like any IT specialty, DevOps is a specific discipline that requires a unique skill set. Just because you have a development background doesn’t mean you can jump right into DevOps.
However, if you are passionate about evolving practices, willing to work in a collaborative environment, and (most importantly) can pick up new skills quickly, then you certainly can build the skills necessary to succeed at DevOps. Typically, DevOps engineers start as sysadmins, developers, testers, performance engineers, support engineers, etc.
If you’re ready to start, here are some skills you should develop today.
1. Learn programming language and skills
First and foremost, DevOps engineers need to be familiar with coding and scripting. Without these skills, you won’t be able to automate tasks or work with code repositories.
To the layperson, coding and scripting may seem like two sides of the same coin. However, they’re quite different:
- Coding is the process of creating software or applications using a programming language like Java, Python, HTML, or CSS
- Scripting is a way of automating tasks using a language like Bash or PERL
There are several specific coding and scripting languages you should familiarize yourself with:
Once you master the basics of coding and scripting, you may realize you need to dive into more specific languages. However, you can work to master that once you have the basics down.
2. Learn cloud computing concepts, designs, & patterns
There are a number of cloud computing concepts that DevOps engineer needs to learn in order to be effective in their role. Here are some of the most important to keep in mind.
The best place to start is understanding the major cloud providers and their unique pros and cons:
- Google Cloud
When you understand the major players, you can aid in selecting the best option for your finished applications.
Source code management
There are several source code management tools that will help you keep your products organized:
Management and organization are especially important as you scale up the number of products and projects you manage and are helpful when you have to collaborate with other team members.
Because DevOps engineers oversee the entire product development lifecycle, it’s important to know the basics of application building from configuration to deployment. This will be critical as you start automating deployment processes to enhance reliability, consistency, and delivery accuracy.
To understand your applications, you need to know the foundation upon which they’re built. The most commonly used operating systems in DevOps are Linux and Windows. While you don’t have to be an OS expert, it’s important to understand key concepts:
- Process management
- I/O management
- Threats and concurrency
- Memory management
Virtualization layers enable multiple OSs to run on a single physical machine, increasing efficiency and lowering costs. Familiarize yourself with platforms like VMware, VirtualBox, Hyper-V, and similar systems.
Containers are similar to VMs, but are more lightweight and have better performance. Familiarize yourself with Docker, Kubernetes, and similar systems.
Configuration management tooling
Configuration management tooling automates the provisioning and configuration of infrastructure components, including:
- Software installation
- System setting configuration
- User account creation and management
Familiarize yourself with tools like Puppet, Chef, and Ansible.
Monitoring & observability
As a modern DevOps engineer, odds are you’ll be working with decentralized, distributed systems and generating terabytes of disconnected data—some of which may contain critical information about your system performance.
As such, it’s important to have integrated observability and monitoring tools to identify key indicators from a single pane of glass and make corrections and changes as they arise. Understanding how to use full-stack observability tools—like Middleware —can help you dramatically improve your DevOps skills.
Leverage Middleware to analyze, diagnose & predict issues across your entire stack.
Networking and security
As a DevOps engineer, you’ll be required to deal with various servers, connections, data transfers, and more. You’ll need to understand networking concepts so you can manage IT workflow.
Additionally, part of your responsibilities as a DevOps engineer is to maintain the security of the overall environment. Make sure to familiarize yourself with security best practices for every stage of the environment.
3. Learn DevOps tools
In addition to general cloud computing concepts and tools, as a DevOps engineer, there are some tools that are specific to your job. The three most important are:
- Application performance monitoring (APM)
- Infrastructure as Code (IaC)
- Continuous Integration/Continuous Delivery (CI/CD) pipelines
Let’s walk through each of these in detail.
Application performance monitoring (APM)
Application performance monitoring (APM) is the practice of tracking performance metrics with monitoring software and telemetry data. APM helps DevOps engineers ensure system availability, optimize performance, and improve user experiences.
In today’s digital world, monitoring includes more than just apps and websites. Monitoring now includes all the services, processes, hosts, logs, networks, and end users that access the applications.
To get real-time metrics, traces and logs in one place.
Infrastructure as Code (IaC)
Infrastructure as Code (IaC) is a methodology that evolved to solve the problem of environment drift in release pipelines. Before IaC, teams had to maintain separate deployment environment settings, with each one becoming a “snowflake” over time—a unique configuration that can’t be reproduced—which leads to inconsistencies that cause deployment issues.
IaC avoids these issues by representing desired environmental states via well-documented code in formats like JSON. IaC is repeatable and can prevent runtime issues caused by configuration drift or missing dependencies. When your IT teams make changes, they do so at the source, not the target.
IaC is a critical component of DevOps and continuous delivery, as it works to define and deploy infrastructures, such as networks, virtual machines, load balancers, and connection technologies. This will enable your teams to work together with a unified set of practices and deliver supporting infrastructure quickly at scale.
Perhaps the most important thing for DevOps engineers to understand is Continuous Integration/Continuous Delivery (CI/CD):
- Continuous Integration deals with reducing costs and improving efficiencies by integrating code into common repositories
- Continuous Delivery makes software releases faster and more efficient through the automation of validated code to a repository
The most common CI/CD tools are Jenkins, CircleGI, and GitLab.
4. Join the DevOps community on Slack, LinkedIn and other channels
Success in DevOps is about more than technical skills. It has its own culture: values, norms, and practices. Collaboration, communication, and integration with other professionals are key.
That’s why building your resume and integrating with the online DevOps community is important. You can start by searching for keywords related to DevOps on LinkedIn to spot relevant communities. Once you’ve joined them, you can use LinkedIn automation to network with others to get integrated well into the industry and understand its culture. Key principles of DevOps culture include:
- Automating tasks to increase speed and reduce human error
- Continuously integrating and delivering code so new features can be released faster
- Closely monitoring system performance to identify issues early and prevent them from becoming critical
- Collaboration among teams and functions to get at the best quality product
By learning the DevOps culture, you can start adopting the habits and behaviors that will make you successful in such an environment.
Here are some tips for learning more about and integrating into DevOps culture:
- Find online DevOps communities—like DevOpsCube and DevOps.com
- Attend DevOps events and conferences
- Participate in hackathons to demonstrate your skills

Learn to embrace the change, make the transition slowly and incrementally, and be open to learning new ways of working.
2. Cross-functional expertise
If you’ve been a specialist your entire career, you may struggle to become a DevOps engineer. DevOps teams don’t work in silos. You have to be comfortable working across functions and accepting responsibility for features and products across their entire lifetime.
3. Moving from legacy applications to microservices
Technology is constantly evolving. Even if you’re an expert on legacy systems, you won’t be able to rely on that knowledge to be successful in DevOps. Learn about the newer microservices architectures that enable faster development and innovation. And keep learning—because the rate of innovation isn’t going to slow down.
Full-stack observability fills in blind spots and provides IT, teams with complete visibility across application components, dependencies, and performance metrics. This enables you to better understand system behavior, performance and health.
4. Speed of innovation
In the same vein, DevOps shortens release cycles, meaning that you have less time to build, test, and deploy changes. It can be difficult for those who aren’t accustomed to this speed of innovation. Start familiarizing yourself with automation tools that can make your life and world easier and more efficient.
5. Interpersonal skills
Gone are the days of the anti-social IT engineers who just sit in a room doing code. If you want to be a DevOps engineer, a key skill set will be bringing all stakeholders together—from development to operations to QA, business executives, product managers, and sales and marketing—to collect feedback. Part of your role will be to foster a culture that encourages all teams to work together to deliver value.
