3. SRE and Platform Engineering - Main Goals and Objectives
Platform Engineering focuses on creating
self-service provisioning, standardized
environments, and efficient deployment
pipelines
SRE focuses on automating tasks,
streamlining incident response, and
reducing toil
Platform Engineering focuses on creating
a scalable, stable and resilient platform
infrastructure.
SRE provides insights into
performance bottlenecks and helps
optimize system scalability

SRE and Platform Engineering work together to ensure systems can scale effectively to meet
growing demands while aim to ensure reliability and availability.

4. What is SRE?
Vestibulum nec congue

Lorem ipsum dolor sit dolor amet,
consectetur nec adipiscing elit, sed
do ipsum eiusmod tempor. Donec
facilisis lacus eget sit nec lorem
mauris.
Vestibulum nec congue
tempus
Lorem ipsum dolor sit dolor amet,
consectetur nec adipiscing elit, sed
do ipsum eiusmod tempor. Donec
facilisis lacus eget sit nec lorem
mauris.
"SRE is what
happens when you
ask a software
engineer to design
an operations
team."
Google SRE Book
"SRE is what you
get when you
treat operations
as if it’s a
software
problem…"
Google

5. Why SRE?
SRE serves as a practical
embodiment of DevOps,
implementing principles and
practices to ensure reliability,
scalability and efficiency in
systems ops
DevOps is a
philosophy that
unifies Developers
and Operations

6. What is SRE? :: Key Principles
SRE principles contribute
to the reliability and
performance of software
systems by emphasizing
proactive monitoring,
incident response, error
budget management,
and continuous
improvement to ensure
high availability and
optimized performance.

"Platform engineering is the discipline of
building and operating self-service internal
developer platforms (IDPs) for software
delivery and life cycle management" Gartner

● Donec risus dolor porta venenatis
● Pharetra luctus felis
● Proin in tellus felis volutpat
Supports CI/CD

05 ● Provides infrastructure, tools, and pipelines for automated build, test,
and deployment processes
Infrastructure
as Code (IaC)
04 ● Embraces Infrastructure as Code principles
Self-Service
03
Automation
02
● Automates repetitive tasks and processes
● Saves time, reduces errors, and accelerates software delivery
● Examples: provisioning environments, building and testing code, deploying
applications
● Enables teams to provision and manage their own resources and services
● Reduces dependencies and minimizes bottlenecks in development and
deployment processes
● Establishes standardized practices, tools, and frameworks
● Reduces complexity and streamlines processes
● Ensures consistency and improves efficiency across the organization
Standardization

12. How SREs can benefit from Platform Engineering
● Implementing an IDP internaldeveloperplatform.org:
○ Improve Developer experience and productivity
■ Faster onboarding of new team members
■ Reduce developers cognitive load
■ Reduce time spent provisioning and maintaining new systems while:
● Guardrails best practices/standards
● Address regulatory requirements
● Reduces the burden of cumbersome internal processes "bureaucracy"
○ Reduces toil
○ Improves team efficiency
○ Free up SRE time to work on noble matters

13. Platform Engineering IDP Approach
● Establish a Platform Team to work on the IDP
● IDP approach:
○ CLI (Command line interface) + Crossplane (crossplane.io)
■ Code Repository(GitHub):
● Initial repository creation based on predefined templates with best practices in
place as observability, hardening, etc…
● CI/CD creation and deploy in multiple environments as STG/Prod/etc
● Repository of templates open to the Engineering team to collaborate
○ Backstage (backstage.io) - Developer Portal
■ Service Catalog
■ Self-service Documentation
■ Code Visibility / System dependencies
■ Open source plugins
