• Docker: A containerization platform used to package applications and their dependencies into containers for easy deployment and scalability.
• Kubernetes: An open-source container orchestration platform used for automating deployment, scaling, and management of containerized applications.
• Ansible: An open-source automation tool used for configuration management, application deployment, and task automation.
• Chef: A configuration management tool used to automate the deployment and management of infrastructure.
• Puppet: Another configuration management tool used for deploying, configuring, and managing servers and applications.
• Grafana:A data visualization and monitoring tool used to create dashboards for monitoring and analyzing metrics from various data sources.

Essential Skill Sets Used by DevOps Professionals

Professionals in DevOps need a broad range of skills, including both non-technical and technical aptitudes. The following are essential skill sets that DevOps professionals use:

• Automation Proficiency: DevOps underscores the importance of automation in streamlining operations. Mastery in scripting languages such as Bash, Python, or PowerShell is indispensable for automating recurring tasks.
• Infrastructure as Code (IaC) Expertise: Grasping IaC principles and utilizing tools like Terraform, AWS CloudFormation, or Azure Resource Manager (ARM) Templates is pivotal for effectively managing and provisioning infrastructure.
• Containerization Mastery: A comprehensive understanding of containerization platforms like Docker and container orchestration technologies such as Kubernetes is imperative for developing scalable and resilient applications.
• Continuous Integration/Continuous Deployment (CI/CD) Competence: DevOps practitioners should excel in establishing CI/CD pipelines using tools like Jenkins, GitLab CI/CD, or CircleCI to automate the software delivery process.
• Version Control Systems (VCS) Proficiency: Acquiring expertise in version control systems like Git, coupled with a deep understanding of branching strategies and workflows, is essential for proficiently managing code changes.
• Configuration Management Skills: Proficiency in configuration management tools like Ansible, Puppet, or Chef is essential for automating the setup of servers and applications.
• Monitoring and Logging Proficiency: DevOps professionals should possess adeptness in monitoring tools such as Prometheus, Grafana, ELK stack (Elasticsearch, Logstash, Kibana), or Splunk to track system performance and identify issues.
• Cloud Computing Platform Understanding: A thorough comprehension of cloud computing platforms such as AWS, Azure, or Google Cloud Platform (GCP) and their services is indispensable for deploying and managing applications in the cloud.
