What is SRE?
Definition:
Site Reliability Engineering (SRE) is a discipline that incorporates software 
engineering principles into IT operations to create scalable and reliable 
systems.
Core Idea: 
Automate and innovate to reduce toil, improve efficiency, and ensure reliability.

Core Goals of SRE
Primary Goals:
1. Reliability: Ensure services meet user expectations.
2. Scalability: Design systems that grow without compromising 
performance.
3. Efficiency: Automate repetitive tasks to improve productivity.
4. Innovation: Free up time for creative problem-solving.

Principle 1 - Emphasizing SLIs, SLOs, and SLAs
 Service Level Indicators (SLIs): Metrics that measure 
system performance (e.g., latency, uptime).
 Service Level Objectives (SLOs): Target values for SLIs to 
meet user expectations.
• Service Level Agreements (SLAs): Contracts with penalties 
for failing to meet SLOs.

Principle 2 - Error Budgets
 Definition:
An error budget is the allowable margin of failure within the 
SLO.
 Purpose:
Balances reliability with innovation by defining acceptable risk.
• Example:
99.9% uptime means 0.1% downtime is acceptable.

Principle 3 - Automation to Reduce Toil
 Toil: Repetitive, manual tasks with no enduring value.
 Automation Benefits:
o Reduces human error.
o Frees up time for innovation.
o Increases consistency and reliability.
 Examples: Automated deployments, monitoring, and 
incident responses.

Principle 4 - Incident Management
 Key Focus:
o Proactive monitoring to detect issues early.
oWell-defined incident response processes.
o Blameless post-mortems to learn from 
failures.
• Outcome:
Reduced downtime and faster recovery.

Principle 5 - Collaboration and Culture
 DevOps Philosophy:
SRE bridges the gap between development and 
operations.
 Focus Areas:
o Cross-functional collaboration.
o Shared responsibility for reliability.
• Encouraging innovation while maintaining stability.

Closing Thoughts
 Summary of SRE Principles:
1.Focus on reliability and scalability.
2.Use SLIs, SLOs, and error budgets to balance 
priorities.
3.Automate wherever possible.
4.Build a culture of collaboration and learning.
• Takeaway: SRE is about making systems reliable, 
scalable, and efficient while fostering innovation.
