The DevOps Roadmap
Understanding Operating System Concepts
Knowledge about process management, threads, parallelism, sockets, I/O management, virtualization, memory storage, and file systems is crucial.
Master the Terminal:
Command-line proficiency, especially in Linux, is vital. Familiarity with Linux shells like Bash or Ksh and tools like find, grep, awk, sed, lsof, and networking commands like nslookup and netstat is required.
Network and Security:
In the interconnected world of today, understanding network and security concepts like DNS, OSI model, HTTP, HTTPS, FTP, SSL, TLS, etc., is essential.
Learn about Servers:
As a DevOps engineer, you should know how to configure a web server like IIS, Apache, and Tomcat. Knowledge about caching servers, load balancers, reverse proxy servers, firewalls, etc., is also necessary.
Learn Infrastructure as Code (IaC):
Containers like Docker and Kubernetes, configuration management tools like Ansible, Chef, Salt, and Puppet, and infrastructure provisioning tools like Terraform and CloudFormation are crucial.
Learn Continuous Integration/Continuous Delivery (CI/CD) Tools:
Tools like Jenkins, TeamCity, Drone, etc., are used to create a pipeline for continuous integration and delivery.
Learn Software Monitoring:
Monitoring is a crucial aspect of DevOps. Therefore, knowledge about infrastructure and application monitoring tools like Nagios, Icing, Datadog, Zabbix, Monit, AppDynamic, New Relic, etc., is required.
Learn about Cloud Services:
Cloud is the next big thing, and knowledge about popular cloud providers like AWS, Google Cloud, Azure, Heroku, Cloud Foundry, and Digital Ocean is beneficial.
Becoming a DevOps engineer requires a broad set of skills, from programming and system administration to networking and security.
This roadmap provides a comprehensive guide to the skills and tools you need to master to become a successful DevOps engineer. Remember, the journey to becoming a DevOps engineer is a marathon, not a sprint. Take one step at a time, and you’ll eventually reach your goal.
