Microservices architectures are revolutionizing the way software is envisioned and built. OpenStack has started to play a key role in enabling the microservices architectures and focused groups inside OpenStack community are working towards this goal: Magnum, Kuryr etc. Docker is one of the key components here and combining them all, we get to build microservices architectures using tools like Docker Swarm, Etcd, Kuryr and Neutron. This workshop will provide attendees with the opportunity to gain experience with various Docker features and uses cases integrated with the OpenStack ecosystem. The lab will cover wide range of topics: Introduction to Docker and OpenStack Docker Swarm: Architecture and usage Etcd Kuryr and Neutron: Architecture and usage with DevStack Deploying Microservices Breaking Docker, Kuryr and debugging it! Attendees simply need to come in (with their laptop). Workshop speaker/organizer will provide instructions and will be available to answer any questions.

Introduction to Microservices
Monolithic services vs Microservices
5
• Monolithic
• All in one application with single big unified code base
• Comprises of multiple small components packaged as one
• Entire application grows overtime with each component growth
• Harder to maintain overtime, especially upgrades and troubleshooting
• Microservices
• Divide and conquer
• Move each component into a separate service entity
• Connect via APIs
• Code base is easier to manage
• Deploying is easier and upgrade downtimes are reduced
• Easier to scale/replace a component

• Distributed K/V store based on
directories
• Service definition queried using
JSON-based HTTP APIs
• Clients handle failure or load
balancing themselves
• Allows watch on changes

Virtual Domains
Your Private Virtual Data Center
12
• Tenant Virtual Domains
• Isolation & segmentation of workloads
• Self-service provision of all functions
• Service Virtual Domains
• Owned by Cloud Operator
• Used to apply common services or
security policies
• Hosts external connectivity
• Virtual Domain Chaining
• Decouple changes from physical
infrastructure
• Fully distributed within IO Visor layer

Distributed Virtual Network Functions Description
Connector
• Connectivity: External, Port Bundle (“Multi-gateway LAG”),
Appliance and Inter Virtual Domain
Bridge
• Distributed Layer 2 network function
• Connects VMs on same IP subnet inside Virtual Domain
• Include Private VLAN functionality
Router
• Distributed Layer 3 network function
• Connects VMs from different subnets inside a Virtual Domain
• Includes Dynamic Routing Protocols (RIP, OSPF, BGP)
DHCP
• Distributed DHCP function for dynamic IP Address allocation
• Associated on per Bridge basis
NAT
• Distributed Network Address Translation function
• Supports Inbound / Outbound, Many to One, One to One NAT
Security Policies
• Distributed Layer 4 Security network function
• Substitute for Layer 4 ACLs / Firewalls
DNS • Distributed Domain Name Service
