Learn DevOps from scratch: A Quick and Easy Guide 2024

DevOps: Learn, adapt, and automate — the heartbeat of modern software excellence.

Introduction to DevOps:
DevOps is a collaborative approach to software development and IT operations, aiming to automate processes and enhance efficiency.

Key Principles of DevOps:
Core principles are Culture, Automation, Measurement, and Sharing (CAMS), emphasizing collaboration and continuous improvement.

Continuous Integration (CI):
CI automates code integration and testing, ensuring regular and reliable updates.

• Jenkins
• Travis CI
• CircleCI
• GitLab CI/CD
• Bamboo

Continuous Deployment (CD):
CD automates the entire release process, allowing frequent and consistent eployments.

• Spinnaker
• ArgoCD
• Harness
• DeployHub

Infrastructure as Code (IaC):

IaC uses code to manage and provision infrastructure, ensuring consistency and reproducibility.

• Terraform
• AWS CloudFormation
• Azure Resource Manager (ARM)
• Pulumi

Version Control:
Git, a version control system, tracks changes, facilitates collaboration, and manages project versions.

• GitHub
• GitLab
• Bitbucket

Monitoring and Logging:
Monitoring tracks system performance, while logging captures events, aiding in troubleshooting. ELK stack is a common tool.

• Prometheus
• Grafana
• ELK Stack (Elasticsearch, Logstash, Kibana)
• Splunk
• New Relic

Security in DevOps:
DevSecOps integrates security into the development process, using tools like OWASP ZAP for early vulnerability identification.

• SonarQube
• OWASP ZAP
• Aqua Security

DevOps Best Practices:
Automated testing, continuous integration, code reviews, and thorough documentation are essential practices for success.

Future Trends in DevOps:
Future trends include AIOps, GitOps, and continued evolution of cloud-native technologies like microservices and serverless architectures. Stay informed for ongoing success.
