Dev Problem
Developers love to create applications and hate to administer servers
Ops Problem
DevOps is a Software Development Method
Automation, Integration, Measurement, Communication, Collaboration
• Initial setup of the dev, test, staging and production environments
• Configuration of access policies for different user groups
• Integration with code repository tools like git and svn
• Deployment automation, like git-push-deploy
• Zero downtime deployment (ZDT), rollback
• Automation of the scaling
• Monitoring and troubleshooting – logs, debugging, performance analysis
• Applying security patches and middleware stack updates
DevOps Tasks

Docker Containers
Docker Usage Overview
Multiplicity of
stacksDo services and apps
interact properly?
Multiplicity of HW
environmentsCan I migrate
smoothly and easy?
The Challenge
Multiplicity of
goodsCan I place coffee and
spices?
Multiplicity of
methods of
transporting
Can I transport from
train to truck?
Cargo Transport Pre-1960
Solution: Intermodal Shipping Container
An engine that enables any
payload to be
encapsulated as a
lightweight and portable
self-sufficient container
That can be manipulated using
standard operations and run
consistently on virtually any
hardware platform
Docker Shipping Container
Virtual Machines VS Containers
Microservices = Decomposition
Complex apps are composed of small, independent processes
Monolithic Application
‒ Very often we redeploy everything
‒ Mutual dependencies slow down
development
‒ Long QA cycle leads to less often updates
‒ High risk of failure or VM overload
‒ Very hard to scale
Modular and polyglot
Deployed and updated independently
Much easier to scale and maintain
Flexibility is the key
