This document discusses building a Platform as a Service (PaaS) on top of the CloudStack cloud computing platform. It outlines several open source PaaS solutions like AppScale and Cloud Foundry that can be used on CloudStack and discusses challenges in areas like auto-scaling, deployment, and network configuration. The document also highlights a demonstration of AppScale running successfully on CloudStack and the potential to run the proprietary Stackato PaaS, which is based on Cloud Foundry, on CloudStack by supporting its required languages and frameworks.

1. Building a PaaS on top of CloudStack
BACD Amsterdam 2013, June 13th

2. Agenda
 PaaS vs. Open PaaS
 PaaS on top of CloudStack
 AppScale (OS)
 Cloud Foundry (OS)
 Stackato (CF proprietary)
 CumuLogic (proprietary)
 Choosing an Open PaaS solution on top of Apache CloudStack
 AppScale
 Cloud Foundry (with BOSH?)
 Challenges and Solutions
 Auto-Scaling
 Hybrid Cloud with AWS / GCE / GAE?
 Metamesh CloudCache (Infinispan)
 Supporting „ANY“ Language and „ANY“ Framework
 Real World Demo (What Enterprise Customers are looking for)

3. PaaS vs. Open PaaS
 AppScale (OS)
 AppScale implements Google's Cloud Platform, App Engine, in open source
 Focused on Python, Java and GO
 CF: Cloud Foundry (OS)
 Open Source PaaS from VMWare, now belongs to Pivotal (GE, EMC, VMWare)
 Will be supported on OpenStack / vSphere and AWS through Pivotal
 Can, could or should be supported through Apache / Citrix for CloudStack?
 Stackato (based on CF, proprietary)
 Developed by ActiveState
 Cloud Foundry LXC enhanced version (proprietary)
 Runs on Citrix CloudPlatform (XenServer) out of the box
 Shall run on Apache CloudStack 4.1 with XCP / KVM
 Claims to be Polyglot: support „ANY“ Lang. and „ANY“ Framework (also .Net )
 CumuLogic
 Founded by top SUN Guys (proprietary)
 Supports Java, PHP, DbaaS, ElasticCache, LBaaS

4. Open PaaS solution on top of
Apache CloudStack
 AppScale
 Works! 100% Open Source.
 Was shown on top of CloudStack on CeBIT 2013
 Challenges: Auto-Scaling on top of CloudStack
 Auto-Scaling supported on EC2 and Eucalyptus
 Cloud Foundry
 Claims to remain Open Source
 Comes with proprietary Web-Interface similar to Stackato Console (in
Sep. 2013)
 Challenges: Build and Deploy with BOSH on CloudStack
 Use Chef, CFengine, Puppet?
 Configure the Network (Multicast / UDP support)
 Integrate with Infinspan (Data Grid Platform)
 Cloudify OLD Java applications
 Other OS PaaS Solutions: RedHat OpenShift Origin on CloudStack?
 How, Why, Why not?

5. AppScale on CloudStack

6. AppScale rock & rolls on CloudStack 

7. StackCloud (Stackato on CloudStack)
