Cloud Foundry & Cloud on a Stick

Cloud Foundry is an open PaaS project that has been gaining in popularity. One of the cool Cloud Foundry related tools is called Micro Cloud Foundry (AKA “cloud on a stick”). It allows developers to run a lightweight Cloud Foundry environment on their development machine. This session will give a quick introduction to the Cloud Foundry platform and highlight the benefits (and limitations) of using Micro Cloud Foundry in the development of cloud based applications. The examples will primarily be shown in Java, but Micro Cloud Foundry can be used for Scala, Node.js, and Ruby as well.

1. Cloud Foundry & Cloud on a Stick Greg Zimmer
2. • Open Platform as a Service project – www.cloudfoundry.org – Apache License 2.0 – https://github.com/cloudfoundry/ Cloud Foundry
3. • CloudFoundry.com – Public instance of Cloud Foundry – Operated by VMware – Running on vSphere infrastructure – Currently in public beta Cloud Foundry
4. • classic.cloudfoundry.com – Previous VMware project – Focused on deploying and managing Java apps on Amazon Web Services Cloud Foundry
5. Open PaaS
6. • Languages – Java, Ruby, JavaScript, Scala, Groovy – PHP *, Python *, Erlang * • * not available in Micro Cloud Foundry or CloudFoundry.com Supported Technologies
7. • Framework integration – Spring, Rails, Sinatra, Node.js, Grails, Lift, … – Extensible to support any framework – Latest code also supports worker processes Supported Technologies
8. • Spring Tool Suite / Eclipse • Maven • Scriptable Command Line Interface • Client libraries for Java, Ruby, & Node.js • REST API Tool Integration
9. – Relational Databases • * vFabric Postgres – NOSQL Databases * not included in Micro Cloud Foundry or CloudFoundry.com – Messaging Service Available Services
10. • Infrastructure Support – Any recent Ubuntu instance – Amazon Web Services – VMware vSphere – OpenStack Cloud Providers
11. • Cloud Foundry based Public PaaS – CloudFoundry.com – AppFog.com – Tier3 Cloud Providers – Uhuru – Iron Foundry
12. Built on Cloud Foundry • Iron Foundry • Stackato • Piston Enterprise OS • Uhuru, AppFog, etc.
13. Cloud Foundry Architecture • Client Layer • Core components – Implemented in Ruby – Using Async Rails 3 & NATS pub / sub – “self healing” • Execution Agents & Services
15. Side Note… BOSH • Tool chain for – release engineering – deployment – lifecycle management …of large scale distributed services • https://github.com/cloudfoundry/bosh • “BOSH: What, How, When” by Dr Nic
16. Cloud on a Stick • Micro Cloud Foundry • Downloadable Virtual Machine running an instance of Cloud Foundry • Fits on a thumb drive • Fastest route to a local instance
17. • Same language and framework support as CloudFoundry.com • Available services • Integration with Spring Tool Suite • Integrated dynamic DNS • Offline mode Cloud on a Stick - Features
18. • Single Node Cloud instance – VM: 1GB RAM, 16 GB disk – 16 Services, 16 Apps • Does not include additional languages, frameworks, or services – PHP, Python, Erlang, Neo4J, etc • Does not support worker processes (yet) • Requires CloudDevelop.com account Cloud on a Stick - Limitations
21. Examples
22. 1. vmc push 2. create app 3. Create droplet 4. Find DEA 5. Deploy droplet 6. Start app 7. Update routes
