Configuration is crucial for efficient software development. Inefficiently configured tools can waste valuable time, while well-configured ones can significantly enhance productivity. For those looking to launch a career in DevOps, mastering the right tools is paramount.
Terraform is designed specifically for creating infrastructure as code in an automated fashion, streamlining processes. Ansible focuses on server configuration, ensuring servers meet specified configurations. These technologies are fundamental in DevOps and utilize YAML-based configuration files.
Learning Terraform basics can take about a week. Consider exploring Terraform courses from platforms like More than Certified. For Ansible, DevOps courses from ExitCertified offer valuable resources.
Version control is essential in DevOps, enabling faster code creation and review within teams, eliminating time wasted on file sharing.
Git is a standalone version control system typically used locally. GitHub provides cloud-based version control, managed by GitHub. In infrastructure as code, version control systems like Git and GitLab are vital.
GitLab is a comprehensive open-source DevOps platform, facilitating faster software delivery with integrated collaboration and security. To learn Git for DevOps, resources like Udacity’s Git basics course can quickly get programmers started.
Packaging bridges build and release management, combining code and infrastructure for deployment.
Docker is central to DevOps, enabling code execution in isolated containers, simplifying service building and replacement, a more efficient approach than monolithic updates.
Amazon’s Lambda is a Docker alternative used by many companies. While knowing both is beneficial, Docker is an excellent starting point and can be learned in a few days. More than Certified offers a beginner-friendly online DevOps course for Docker.
Deployment involves moving code from version control to application users. Automation is key, and Jenkins is a primary tool for this.
Jenkins automates tasks like build tests and decision-making based on build outcomes. It also manages scripts and executes commands via SSH.
Jenkins automates repetitive tasks more efficiently than manual DevOps processes. CodeDeploy is another deployment tool some companies prefer.
Jenkins can be learned in a few days. More than Certified provides an online course bundling Terraform, Ansible, and Jenkins. Also, explore tutorials like “How to Manage Terraform With Jenkins – Step by Step Tutorial”.
Kubernetes builds upon Docker, adding functionalities for container management. It ensures multiple container image copies run, maintaining service availability even if a VM or host fails.
ECS and Kubernetes automate container management, enhancing availability, role-based access control, and centralized auditing.
IBM’s Kubernetes learning path offers a 13-hour course, and resources like a guide to Kubernetes certification are available.
Monitoring application status post-deployment is crucial, and DevOps engineers often use the ELK Stack.
ELK provides components for log management and search: Elasticsearch, Logstash, and Kibana, open-source applications from Elastic.
ELK visualizes data from various sources using charts and graphs. Prometheus is a comparable monitoring platform. The ELK Stack can be learned in a few days with Udemy’s online class.
These are fundamental tools for starting a DevOps career. For platform-specific DevOps learning, More than Certified offers a comprehensive curriculum.
Understanding these tools and how to use them effectively is your first step in getting the tools you need to start a successful DevOps career.
