Python
Python is a top choice for DevOps and SRE engineers working across AWS, Azure, and GCP. Its versatility, rich ecosystem, and strong cloud SDK support make it ideal for automating infrastructure, integrating with CI/CD, and building cloud-native solutions.
Why DevOps & SREs Should Learn Python
Cloud Automation: Python SDKs for AWS (boto3), Azure, and GCP enable engineers to automate provisioning, scaling, and management of cloud resources.
IaC & Configuration: Python is used in tools like Ansible, Pulumi, and custom Terraform modules for advanced automation.
CI/CD Integration: Python scripts are common in GitHub Actions, Azure Pipelines, and GitLab CI/CD for deployment, testing, and monitoring.
Observability & Monitoring: Python powers log analysis, custom Prometheus exporters, and alerting integrations.
LLM & AI Integration: Python is the primary language for integrating Large Language Models (LLMs) into DevOps workflows (e.g., using OpenAI, Azure OpenAI, or Hugging Face APIs).
Real-Life Examples
1. AWS EC2 Instance Automation (boto3)
2. Azure VM Creation (Azure SDK)
3. GCP Cloud Storage Bucket Creation (google-cloud-storage)
4. Integrating LLMs for Automated Change Summaries
5. CI/CD Pipeline Step (GitHub Actions)
Best Practices (2025)
Use virtual environments (venv, pipenv) for dependency management
Store secrets securely (AWS Secrets Manager, Azure Key Vault, GCP Secret Manager)
Write idempotent scripts for infrastructure changes
Integrate Python scripts with CI/CD for repeatable automation
Use logging and exception handling for observability
Test automation code with pytest or unittest
Common Pitfalls
Hardcoding credentials in scripts
Not handling API rate limits or errors
Ignoring dependency pinning (requirements.txt)
Lack of logging and monitoring
Not using version control for automation scripts

Python Joke: Why did the DevOps engineer love Python scripts? Because they always passed the test—unless they were indented wrong!
