Continuous Integration and Continuous Deployment (CI/CD) are essential for modern software development. GitHub Actions provides a powerful way to automate your workflow, allowing you to build, test, and deploy your code right from GitHub.

Infrastructure as Code (IaC) allows you to manage and provision your infrastructure through code instead of manual processes. Terraform is one of the most popular tools for this, supporting multiple cloud providers like AWS, Azure, and GCP.

Kubernetes has become the de facto standard for container orchestration. It helps in automating deployment, scaling, and management of containerized applications, ensuring high availability and resource efficiency.

As systems become more complex, monitoring and observability become crucial. Understanding the health and performance of your microservices is key to maintaining a reliable system. Tools like Prometheus and Grafana are industry standards.

Site Reliability Engineering (SRE) is a discipline that incorporates aspects of software engineering and applies them to infrastructure and operations problems. The goal is to create scalable and highly reliable software systems.
