Most sought-after DevOps skills you must know in 2023

In today’s fast-paced software development world, DevOps is a term that has become increasingly popular in recent years. It is a culture that emphasizes collaboration and communication between development and operations teams to improve the software development process. As more organizations embrace DevOps, it has become essential for IT professionals to have the necessary skills to succeed in this field. In this article, we will discuss the most sought-after DevOps skills you must know in 2023. These skills are critical for IT professionals looking to stay relevant in the current job market and advance their careers in DevOps.

Knowledge on Cloud Computing

Cloud computing has revolutionized the way we build and deploy applications. It has enabled organizations to scale their operations seamlessly and cost-effectively. DevOps professionals must have a strong understanding of cloud computing, including the various cloud providers, their services, and deployment options. Some of the popular cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

AWS is the most popular cloud provider, and a DevOps professional must have experience with services such as EC2, S3, and RDS. Microsoft Azure is also popular, and a DevOps professional must be proficient in services such as Virtual Machines, App Services, and Azure Functions. GCP is also gaining popularity, and a DevOps professional must understand services such as Compute Engine, Cloud Storage, and Cloud Functions.

Knowledge on Containerization

Containerization has become a popular way of deploying applications. It enables organizations to package their applications into portable containers that can run on any platform. DevOps professionals must be proficient in containerization technologies such as Docker and Kubernetes. Docker is the most popular containerization technology, and a DevOps professional must have experience with Dockerfiles, Docker Compose, and Docker Swarm.

Kubernetes is also becoming increasingly popular, and a DevOps professional must understand its architecture and components. A DevOps professional must be able to deploy, manage and scale applications on Kubernetes clusters. They must also understand Kubernetes objects such as pods, services, deployments, and stateful sets.

Knowledge on Infrastructure as Code

Infrastructure as Code (IaC) is a DevOps practice that involves managing infrastructure using code. IaC enables organizations to automate the provisioning and management of their infrastructure. A DevOps professional must be proficient in IaC tools such as Terraform, CloudFormation, and Ansible. Terraform is a popular IaC tool that enables organizations to manage infrastructure as code across multiple cloud providers. CloudFormation is an IaC tool provided by AWS, and a DevOps professional must understand its templates and resources. Ansible is also popular, and a DevOps professional must be able to write playbooks for automating infrastructure management.

IaC enables organizations to automate the provisioning and management of their infrastructure, which reduces the risk of errors and increases efficiency. A DevOps professional must understand how to write infrastructure code using IaC tools.

Knowledge on Continuous Integration and Continuous Delivery

Continuous Integration (CI) and Continuous Delivery (CD) are DevOps practices that involve automating the software development process. CI involves continuously integrating code changes into a central repository, testing them, and building them into executable artifacts. CD involves continuously deploying the executable artifacts to production.

A DevOps professional must be proficient in CI/CD tools such as Jenkins, GitLab CI/CD, and CircleCI. Jenkins is the most popular CI/CD tool, and a DevOps professional must be able to set up and configure Jenkins pipelines. GitLab CI/CD is also becoming increasingly popular, and a DevOps professional must understand its CI/CD pipelines and runners. CircleCI is also popular, and a DevOps professional must be able to write and manage workflows.

Knowledge on Monitoring and Logging

Monitoring and logging are essential for maintaining the health of applications and infrastructure. DevOps professionals must be proficient in monitoring and logging tools such as Prometheus, Grafana, and ELK Stack. Prometheus is a popular monitoring tool that enables organizations to monitor their applications and infrastructure. Grafana is a visualization tool that enables organizations to create dashboards for monitoring and logging data. ELK Stack is most vital to;; that is used for the current organization for monitoring. Datadog / Nginx also used frequently for Monitoring and logging.
