Aaron Williams (Head of Advocacy at Mesosphere) and Ryan Lee (Cloud Infrastructure Engineer at 10th Magnitude) demonstrate how to use Mesosphere DCOS on Microsoft Azure to easily deploy Docker containers at scale. This presentation and linked video (https://youtu.be/xNEZFRsANMk) will walk you through: - What microservices are, and why a microservice-based architecture might be the right choice for your company - How to easily deploy DCOS on Microsoft Azure - Several different scenarios for deploying Docker containers using DCOS on Azure http://www.mesosphere.com http://www.10thmagnitude.com

• Disentanglement of monolithic applications
• SOA applied to infrastructure
• Talk to other microservices via API
• Lightweight and scalable
• No standard model

Scales
monolithically
Traditional Architecture
Small number of large processes
with strong inter-dependencies
Many functions
in a single process
Siloed
teams
RESTAPIs
Microservices Architecture
Cross-functional teams creating new
microservices without interdependencies
Cross-functional
teams organized
around capabilities
Scales
individually
Each element of
functionality defined as
“microservices”

compute resources away from machines (physical or virtual),
enabling fault-tolerant and elastic distributed systems to
easily be built and run effectively.”

• Still have to manage infra VMs (Solved with CoreOS)
• Database support not as mature (Working with data-only
containers or Flocker)
• Security patches can be a pain
