The key to success is always the same – learn, practice, test your knowledge and repeat. So, here are the steps to prepare for the Professional Google cloud DevOps exam in 2022:

3.3 Learn about managing servers:

Managing servers is where we monitor and maintain servers so that they operate properly. You need to get some administration knowledge in some OS and learn to live in a terminal.



 3.4 Get knowledge of Networking, Security and Protocols:

DevOps teams always require a segmented network for testing purposes and the DevOps environment needs security from code vulnerability and operational weaknesses before they become an issue. Also, there are several protocols that are followed by the engineers while performing the tasks. One must have knowledge of different protocols like HTTP, HTTPS, FTP, SSL, SSH, SMTP, etc.

3.5 Things you must know about

There are certain terms you must know about and should know how to set them up, like it is important that you know about reverse proxy, forward proxy, caching server, load balancer, firewall, Web server(Nginx, Istio, Consul)

3.6 Learn infrastructure as code:

IaC is a way of managing the infrastructure through code instead of using manual processes. You must have basic knowledge of containers, configuration management, container orchestration, infrastructure provisioning and service mesh.

3.7 Learn some CI/CD tools:

These are the tools that are used for the automation of steps in development and to provide reporting. Some of these tools are Gitlab CI, Jenkins, GitHub Actions, Circle CI, Travis CI, Bamboo, etc.

3.8 Learn how to monitor software and infrastructure:

This monitoring can be divided into three parts –
  1.  Infrastructure monitoring: For this, we have tools like Prometheus, Nagios, and Grafana, etc.
  2. Application monitoring: For this, we have tools like Jaeger, New Relic, Instana, etc.
  3. Logs management: For this, we have tools like Elastic Stack, Graylog, Splunk, etc.

  • When you don’t understand a question while practicing, go to the depth of that question and try to extract as much knowledge as you can about the topic.
  • Maintain a topic-wise evaluation report of your progress so that at the time of revision you always have an idea of where you need to focus more.
