This Presentation is really good for new comers and i have helped a large audience to understand the new of DevOps.
It will answer Why,How and Basics of DevOps and Histroy with background and practical use cases.

3. Why DevOps?
Before DevOps (SDLC/Waterfall days)
The development and operation team worked in complete
isolation.
Testing and Deployment were isolated activities after design-
build. Consumed more time than actual build cycles
Team members are spending a large amount of their time in
testing, deploying, and designing instead of building the
project (Not so in DevOps)
Manual code deployment leads to human errors in
production.
Coding & operation teams have their separate timelines and
are not in synch causing further delays.
4. Why DevOps ?
After DevOps
A culture change that improves IT service delivery agility on
the basis of
Communication
Collaboration
Integration
Better resource management (No QA ,IT team waiting)
Reduced human errors (Lower the application failure rate
with multiple deployments in production)
Stable Environment and early defect mitigation, faster
deliveries
Quality and delivery now is shared Responsibility
5. DevOps Is/Not?
The term DevOps has been used in multiple context
- is a software engineering culture ?
- practice focusing on software development (Dev) and software
operation (Ops) ?
- A Mindset
- a cross-functional mode of working
- A culture changes based on Lean and Agile
- ≠ Scrum,Others
- Not a Tool – (We do DevOps as we use Jenkins or Ansible?)
- is Not a distinct role or a team rather describes an approach to work
- Is Not Automation or CI or Continuous Delivery
6. History of DevOps
The idea began in 2008 with a discussion between Patrick
Debois and Andrew concerned over the concept of Agile
Infrastructure.
The idea only started to spread in 2009 with the advent of the
first DevOpsDays event held in Belgium
Later Actually evolved as feedback oriented system
It actually covers every aspect of software development from
coding all the way through the various stakeholders to
deployment.
7. Stakeholders
Key Stakeholders are all key people part of Product Team or Project Team
Marketing, Product Management, Engineering,Sales,Project Management
DBA
Security Eng.
Customer
Production Sup
9. DevOps Lifecycle
DevOps Lifecycle can be broadly broken down into the below
DevOps Stages:
Continuous Development
Continuous Integration
Continuous Testing
Continuous Monitoring
Operations(Virtualization and Containerization)
These stages are the building blocks to achieve DevOps as a whole.
10. DevOps Tools
The most popular DevOps tools are, though these are not limited and number
of open source tools available
Git : Version Control System tool
Jenkins : Continuous Integration tool
Selenium : Continuous Testing tool
Puppet, Chef, Ansible : Configuration Management and Deployment tools
Nagios : Continuous Monitoring tool
Docker : Containerization tool
DevOps Tools are expected to fit into one or more of these categories Code, Build
,Test ,Package, Release ,Configure , Monitor
11. DevOps Goals
A handful of DevOps goals that we keep seeing over and over again
Release on demand
Eliminate technical debt and unplanned work
Fail smart/fast/safe
DevOps Success Mantra
Culture,Culrure,Culture
12. Case Study:
Case 1:
In our IT Company Deployment used to take 12 Hours and release cycle used
to take 3 weeks and 1 week at stagging
After this devops delivery pipeline implementation
Deployment =40 min , R Cycle=3d and customer site deployment=1
Case2:NetFlix
One of best DevOps Technology implementer
Contribution in open source tools development and implementation at
enterprise level
22 Cassandra Nodes replaced with Zero downtime
Top Key companies Amazon,Netflix,Facebook,Etsy etc
