Beginning the Journey to be a Certified DevOps Engineer


In today’s competitive IT world, DevOps engineering is enticing. DevOps engineers are one of the most sought-after IT jobs nowadays. In the last three to four years, the job market has seen a 40% growth in demand for DevOps professionals. DevOps is complex and requires a wide range of skills and knowledge. You’re on the right track to becoming a DevOps engineer!

First, let’s define DevOps

Developers and operations engineers collaborate as part of a team in the DevOps culture. There used to be a clear separation of duties between operations and development in the software industry. There needed to be more oversight from developers, who needed to learn where or how their code was being used.

Journey to become a Certified DevOps engineer

DevOps is a hot career. IDC expects $17.7 billion in revenue from DevOps by 2024. Such growth necessitates more DevOps professionals in all fields. Because DevOps changes so quickly, it’s rare for students to learn all its skills and processes while getting a degree. You don’t have to wait to learn these crucial abilities. Let’s discuss your current needs.

Intermediate to advanced Linux skills

DevOps needs to build a server and check in sometimes to do admin work. Unless you want to be a Windows Server DevOps engineer, you must learn how to create highly customized Linux images for VM and container use cases.

Intermediate networking skills

No “network team” exists in DevOps. Software controls a network. Networks are code-based infrastructures. You should know OSI, IPV4, DNS, and firewalls (static and stateful). DevOps, advanced cloud, and the DevOps engineer certification course teach them.

At least one cloud commitment

Clouds are more than just managed data centers. To automate workloads in the cloud (AWS, Azure, and GCP), you must understand its semantics. Know what resources are available, how they’re structured, and their properties.

Automating infrastructure

Once you know cloud resources and how they work, you can use Terraform and Ansible to create them automatically.

SDLC, scripting, and CI/CD pipelines

Infrastructure is delivered like applications in DevOps. You’ll need to know the basics of the software development life cycle (SDLC). It includes versioning strategies using Git and Jenkins/CircleCI CI/CD pipelines. Advanced automation tasks may be challenging using shell scripts alone. Python, Perl, or Ruby scripting is often needed.

Container technology

For legacy workloads, automate VM image creation. You’ll use containers for new apps. You must develop and deploy Docker images using Kubernetes. Container technology powers FaaS.


While many clouds include monitoring dashboards and standard “telemetry” hooks, most significant employers use third-party (commercial and open source) monitoring solutions like Prometheus, DynaTrace, Datadog, or the ELK stack.

Technologies that DevOps engineers must learn

  • Gradle is a reliable DevOps stack tool. Since 2009, it’s been popular. Apache Ant and Maven ruled for years before Gradle.
  • Git is a standard DevOps tool. The software industry uses Git, a distributed SCM tool.
    Software engineers use Jenkins for DevOps automation. Jenkins is an open-source CI/CD server that lets developers automate the delivery workflow.
  • Bamboo is a Jenkins-like tool. Bamboo, Atlassian’s CI/CD server, automates delivery Bamboo costs money, unlike Jenkins.
  • Docker is a vital DevOps tool. The 2013 rocket is the top container platform.
    Kubernetes works with Docker and its variants. Google employees created the tool in 2015.
  • Puppet is a cross-platform configuration management framework for infrastructure as code. It automates infrastructure management, making software delivery fast and secure.
  • Ansible is straightforward to use. It manages configurations like Puppet and Chef. Ansible simplifies infrastructure configuration and deployment.
  • Open-source, free DevOps monitoring tool Nagios, lets you control your infrastructure to fix problems. Record occurrences, failures, and outages.
  • Raygun is an error and crash reporting platform. Application performance monitoring (APM) is Raygun’s latest product.

Three steps to becoming a certified DevOps Engineer:

Step 1: Get a related bachelor’s degree

DevOps engineers need a bachelor’s degree in computer science, IT, or software design. DevOps engineering benefits from mathematical degrees. DevOps engineers should study these topics:
System architecture
Software development
Cloud architecture

Step 2: Learn required skills you need

DevOps engineers must learn industry skills and expertise next. Managerial-level DevOps engineers need technical and soft skills.

1. Operating Systems (OS):

Operating systems are the most crucial part of computers, whether personal computers or servers that run applications for a business. So, DevOps engineers need to know a lot about the basics of operating systems, such as how to handle processes, sockets, and memory.

2. Infrastructure as Code (IaC):

You can set up servers, networks, and other infrastructures to meet application needs better. IaC automates this procedure, making it possible to deploy and update applications more quickly. Configuration management, infrastructure provisioning, and container management are all essential IaC methodologies.

3. Continuous Integration/Continuous Deployment (CI/CD) Tools:

GitLab, Jenkins, and CircleCI save settings for application deployment specific to the environment and automate operations to make DevOps possible. DevOps engineers should learn these tools.

4. Programming Languages:

DevOps engineers integrate databases, debug code, and automate processes. They must understand Python, Ruby, and Go, the team’s programming languages.

5. Cloud Providers:

Azure and AWS are used for software development, data backup, disaster recovery, and analytics. DevOps engineers must understand each service and how to use these technologies to scale and streamline operations.

Step 3: Online Training and Certification

DevOps credentials boost career prospects. Online certification preparation is helpful. Some employers demand Linux administration credentials. DevOps engineers must also master Ansible, GIT, Kubernetes, Docker, Terraform, and other popular tools. Configuration, source code, and containerization are everyday tasks for DevOps engineers.
The final step is to upgrade your skills!

You now know all the skills of a DevOps engineer. Several market-relevant DevOps certifications will help you start your career as a DevOps engineer. It is a detailed route for DevOps job seekers.

Although becoming a DevOps engineer is difficult, it is worthwhile because there will be many exciting job opportunities. Simplilearn online learning platform will help you land your ideal career.
