Intro
DevOps engineers are responsible for designing, implementing, and maintaining the infrastructure and tools that support the software development process.
To be effective in this role, they need to have a strong set of hard skills. Here are some of the most important hard skills that every DevOps engineer should have:
Programming and scripting: DevOps engineers should have experience with at least one programming or scripting language, such as Python, JavaScript, or Ruby, to be able to automate repetitive tasks and write scripts to deploy and manage infrastructure.
Version control: DevOps engineers should be proficient in using version control systems like Git, to manage and track changes to the codebase.
Cloud computing: DevOps engineers should have experience with cloud computing platforms like AWS, Azure, or GCP. They should be able to work with cloud-based infrastructure, understand the concepts of cloud computing, and be able to deploy and manage applications on these platforms.
Containerization: DevOps engineers should have experience with containerization technologies like Docker and Kubernetes. They should be able to package and deploy software in a portable and consistent manner, which improves the reliability and portability of software.
Automation: DevOps engineers should have experience with automation tools such as Ansible, Puppet, or Terraform, to automate the provisioning and configuration of infrastructure.
Monitoring and logging: DevOps engineers should have experience with monitoring and logging tools such as Prometheus, Grafana, or Elasticsearch. They should be able to collect and analyze data from different systems and applications and use it to troubleshoot and optimize performance.
Infrastructure as code: DevOps engineers should have knowledge of infrastructure as code (IAC) concepts and technologies, this includes understanding of concepts like provisioning, config management, and deployment.
Networking: DevOps engineers should have a basic understanding of network protocols and concepts, such as TCP/IP, DNS, and load balancing. They should be able to troubleshoot and optimize the performance of networks, and understand the impact of network configurations on application performance.
Security: DevOps engineers should have knowledge of security best practices and technologies, such as encryption, authentication, and access control. They should be able to implement security measures to protect applications and infrastructure.
By having a strong set of hard skills, DevOps engineers can be more effective in their role and help to improve the overall performance and reliability of software development teams.
