A simple yet powerful automation engine that uses YAML for defining reusable descriptions of systems.


A service provided by AWS that gives developers and businesses an easy way to create a collection of related AWS and third-party resources, and provision and manage them in an orderly and predictable fashion.

Continuous Integration/Continuous Deployment (CI/CD)

CI/CD tools are fundamental for automating the stages of app development, from integration and testing to deployment. They enable SREs to integrate code changes more frequently and reliably, facilitating a smooth and continuous delivery pipeline.

Popular Tools


An open-source automation server that provides hundreds of plugins to support building, deploying, and automating any project.

GitLab CI/CD

A part of the GitLab platform that automates the entire software development pipeline, from build to deploy, within the same ecosystem.


A cloud-based CI/CD platform that automates the software development process, allowing teams to build, test, and deploy applications rapidly.

Configuration Management

Configuration management tools help SREs maintain consistency of system performance by managing the state of resources such as servers, databases, and applications. These tools are vital for automating system updates and ensuring that configurations are applied uniformly across environments.

Popular Tools


A powerful automation platform that transforms infrastructure into code, enabling SREs to automate how they build, deploy, and manage infrastructure.


An automated administrative engine for managing your infrastructure throughout its lifecycle, from provisioning and configuration to orchestration and reporting.


A Python-based open-source configuration management software and remote execution engine, supporting the "infrastructure-as-code" approach to deployment and cloud management.

Log Management and Analysis

Log management and analysis tools are indispensable for troubleshooting and gaining insights into system behavior. They enable SREs to aggregate, search, and analyze log data across the entire infrastructure, which is crucial for diagnosing issues and improving system performance.

Popular Tools

Elasticsearch, Logstash, and Kibana (ELK Stack)

A group of open-source products designed to help users take data from any source, in any format, and search, analyze, and visualize that data in real time.


A software platform for searching, analyzing, and visualizing the machine-generated data gathered from the websites, applications, sensors, devices, etc. that make up your IT infrastructure and business.


An open-source log management platform that enables fast and efficient log analysis with a user-friendly interface and scalable architecture.
