DevOPS VS SRE - unix1998/technical_notes GitHub Wiki

the core distinctions between DevOps and Site Reliability Engineering (SRE):


  1. Focus on SDLC: DevOps is primarily concerned with the Software Development Life Cycle (SDLC), aiming to improve collaboration between development and operations teams.
  2. Continuous Integration/Continuous Deployment (CI/CD): DevOps practices emphasize automating the integration and deployment of code to ensure faster and more reliable software releases.
  3. Creating New Code and Features: DevOps facilitates the creation of new code and features, focusing on speed and agility in the development process.
  4. Tooling and Automation: DevOps leverages tools to automate various aspects of the development and deployment process, such as version control, build automation, and infrastructure as code (IaC).
  5. Improvement and Innovation: DevOps strives to continuously improve systems and processes, enhancing the overall development and operational efficiency.

Site Reliability Engineering (SRE):

  1. Focus on Reliability and Availability: SRE's primary concern is ensuring the reliability, availability, and performance of systems and services.
  2. Monitoring and Observability: SREs use observability platforms to monitor systems, track performance metrics, and detect issues before they affect users.
  3. Auto-healing and Auto-scaling: SREs implement mechanisms for auto-healing and auto-scaling to maintain system health and performance without manual intervention.
  4. Incident Response and Management: SREs manage incidents, perform root cause analysis, and implement post-mortems to prevent future occurrences.
  5. Service Level Objectives (SLOs) and Error Budgets: SREs define and manage SLOs and error budgets to balance reliability with the pace of development.


  • DevOps: Focuses on improving the overall development and deployment processes, enabling faster delivery of new code and features, and fostering collaboration between development and operations teams.
  • SRE: Focuses on maintaining the reliability and availability of systems, using monitoring, automation, and incident management to ensure that services are working properly and meet defined reliability standards.

Both DevOps and SRE aim to improve the efficiency and reliability of software delivery, but they do so from different angles and with different primary objectives. DevOps enhances the development pipeline and collaboration, while SRE ensures the operational stability and reliability of systems.
