Site Reliability Engineering Certification Course in Hyderabad
                     SRE vs. DevOps
Key Differences
Introduction to SRE and DevOps
 SRE (Site Reliability Engineering): A 
discipline focused on ensuring reliable 
and scalable software systems.
 DevOps: A set of practices that 
combines software development and IT 
operations to shorten the development 
lifecycle.
 Goal: Both aim for continuous delivery 
but approach reliability and operations 
differently.
Origin and Background
 DevOps: Originated from collaboration 
between developers and operations 
teams to improve deployment speed 
and software quality.
 SRE: Emerged from Google’s need to 
manage large-scale systems reliably with 
a focus on automation and monitoring.
 Key Difference: DevOps focuses more on 
collaboration; SRE focuses more on 
reliability engineering.
Core Principles of DevOps
 Collaboration: DevOps fosters a culture 
of collaboration between development 
and operations teams.
 Automation: Automates manual tasks to 
speed up software delivery.
 Continuous Integration/Continuous 
Deployment (CI/CD): Focus on 
automation in the development and 
deployment process.
 Goal: Faster releases and iterations.
Core Principles of SRE
 Service Level Objectives (SLOs): Focus on 
defining and measuring the reliability of 
services.
 Error Budgets: Establish a balance between 
reliability and feature development by 
managing how much failure is acceptable.
 Incident Management: Emphasis on 
proactive incident management and 
minimizing downtime.
 Goal: Prioritize reliability and availability 
while enabling feature development.
Key Responsibilities - DevOps
 Automation of Build and Deployment 
Pipelines
 Infrastructure as Code (IaC)
 Monitoring and Logging
 Collaboration between Developers and 
Operations
 Continuous Integration and Delivery (CI/CD)
Tools Used by DevOps vs. SRE
 DevOps Tools: Jenkins, Git, Docker, 
Kubernetes, Puppet, Chef, Terraform.
 SRE Tools: Prometheus, Grafana, Pager Duty, 
Stack driver, OpenTelemetry, Data dog.
 Key Difference: DevOps tools focus on 
automation, while SRE tools focus more on 
monitoring, alerting, and reliability.
Key Responsibilities - SRE
 Defining and Monitoring SLIs (Service Level 
Indicators)
 Managing SLOs and Error Budgets
 Automation of Operational Tasks
 Proactive Incident Management and Post-
mortems
 Capacity Planning and Scaling
Conclusion - Key Differences
 Focus: DevOps emphasizes collaboration and 
speed; SRE emphasizes reliability and scalability.
 Metrics: DevOps uses deployment frequency and 
speed; SRE uses SLOs, SLIs, and error budgets to 
ensure system reliability.
 Approach to Failures: DevOps embraces failure 
as part of the process; SRE sets limits on 
acceptable failures via error budgets.
 Collaboration vs. Engineering: DevOps is more 
about culture and practices, whereas SRE is a 
role-driven, engineering-focused discipline.
