Docker VIP breakfast at Zenika, 12/16/2014

1. The Future of Distributed Applications
A 10-min overview of Docker, by Julien Barbier, Jérôme Petazzoni & Victor Coisne, at Zenika, Paris, France

2. ~2000 2014
Long lived Development is iterative and constant
Monolithic and built on a single stack Built from loosely coupled components
Deployed to a single server Deployed to a multitude of servers
Apps Have Fundamentally Changed

Solution: Intermodal Shipping Container
…in between, can be loaded and
unloaded, stacked, transported
efficiently over long distances,
and transferred from one mode
of transport to another
A standard container that is
loaded with virtually any
goods, and stays sealed until
it reaches final delivery.

6. This spawned an Intermodal Shipping Container Ecosystem
• 90% of all cargo now shipped in a standard container
• Order of magnitude reduction in cost and time to load and unload ships
• Massive reduction in losses due to theft or damage
• Huge reduction in freight cost as percent of final goods (from >25% to <3%)
 massive globalization
• 5000 ships deliver 200M containers per year

…that can be manipulated using
standard operations and run
consistently on virtually any
hardware platform
An engine that enables any
payload to be encapsulated
as a lightweight, portable,
self-sufficient container…

8. Docker Containers + Ecosystem: Impact
• Massive reduction of application development lifecycle
• Week / month -> Days / hours
• Drastic cost reduction (applications and servers)
• Application development is faster
• From dev to deploy: much faster
• Docker containers use 2 to 30 times less resources than traditional
VMs*
• More freedom
• Docker containers can be moved from one cloud to another with
consistancy -> no more lock-in
• More transparency
• Docker is open-source

9. Who is using Docker?
E-Commerce Media
IT SaaS IaaS
Life Sciences
PaaS
…and thousands of others!
Vertical Search

10. Case Study: New Relic
At-A-Glance
• Application performance
monitoring service
• ~90,000 customers
• Tracks 1+ trillion events / month
• Just filed for their IPO
Challenges
• 50% more servers in 3 months
• Doubling developer count every year
• Increasing heterogeneity:
4 versions of Ruby
3 different JVMs
5 data stores…
Before Docker
• 7 monolithic apps
• Devs doing own deploys
• One-off custom deploy tools
• Everyone had access to BD secrets
• From dev-to-deploy: weeks
After Docker
• 30+ microservices
• Separation of build from deploy
• Single standardized deploy tool
• Improved security
• From dev-to-deploy: hours

11. Why are we here?
• Docker Tour de France 2014
• Paris, Lyon, Lille, Bordeaux, Nice, Monaco
• There are more Docker Meetup groups in Europe than anywhere
else
• Meet the Docker community
• Meet French schools, incubators & accelerators
• Meet French companies
• Understand their needs
• Understand the specificity of the French market and the European
market
• Today there are ~50 companies in the room
