Containers brought new approach for implementation of DevOps workflows. So our CEO, Ruslan Synytsky, devoted a speech to this topic during Madrid meetup and described in details how Java developers can get benefits from Docker containers in Jelastic Cloud.

1. DEVOPS FOR JAVAWITH DOCKER
CONTAINERS

2. Dev Problem
10:15 Install OS
11:20 Configure the system
12:05 Coffee Break
13:05 Configure security
14:15 Configure Web server
15:40 Configure Database
16:20 Couple of sandwiches
16:50 Configure firewall
17:20 Deploy application
17:45 Call wife and apologize for the late return
18:00 Identify library dependencies
20:30 Upgrade packages
22:15 Fix dependencies
23:50 Couple cans of Red Bull
01:30 Run!!!
02:05 The end of the working day

3. Dev Problem
Developers love to create applications
and hate to administer servers

4. Ops Problem

5. DevOps is a Software Development Method
Automation, Integration, Measurement, Communication, Collaboration

6. • 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

8. Docker Containers

9. Docker Usage Overview

10. Multiplicity of
stacks
Do services and apps
interact properly?
Multiplicity of HW
environments
Can I migrate
smoothly and easy?
The Challenge

11. Multiplicity of
goods
Can I place coffee and
spices?
Multiplicity of
methods of
transporting
Can I transport from
train to truck?
Cargo Transport Pre-1960

12. Solution: Intermodal Shipping Container

13. 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

14. Virtual MachinesVS Containers

15. Microservices = Decomposition
Complex apps are composed of small, independent processes

16. 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
