Building an Enterprise Cloud with WSO2 Private PaaS
- 1. Enterprise Cloud with WSO2 Private PaaS Pradeep Fernando Associate Technical Lead, WSO2 Inc. 06th Feb 2014
- 2. About the Presenter ๏ ๏ WSO2 Carbon ๏ CommiFer and PPMC at Apache Stratos(IncubaIng) ๏ 2 Pradeep Fernando Experience in enterprise integraIon
- 3. About WSO2 ๏ ๏ Global enterprise, founded in 2005 by acknowledged leaders in XML, web services technologies, standards and open source Provides only open source plaTorm-‐as-‐ a-‐service for private, public and hybrid cloud deployments ๏ ๏ 3 All WSO2 products are 100% open source and released under the Apache License Version 2.0. Is an AcIve Member of OASIS, Cloud Security Alliance, OSGi Alliance, AMQP Working Group, OpenID FoundaIon and W3C. ๏ Driven by InnovaIon ๏ Launched first open source API Management soluIon in 2012 ๏ Launched App Factory in 2Q 2013 ๏ Launched Enterprise Store and first open source Mobile soluIon in 4Q 2013
- 4. What WSO2 delivers 4
- 5. Todays Webinar… ๏ What/Why is PlaTorm as a Service (PaaS) ๏ Understanding the WSO2 private PaaS architecture ๏ Auto scaling and deployment policies ๏ Cloud bursIng ๏ Towards your very own enterprise cloud
- 6. Why you need a PaaS ๏ ๏ Provision allowed applicaIon types within minutes ๏ Let the PaaS worry about auto scaling of your applicaIon ๏ 6 OrganizaIon wide visibility through monitoring/ billing and metering Build your own service plaTorm on top the PaaS.
- 7. At the Very Heart of PaaS ๏ Create a VM image that runs on a specific IaaS ๏ This image contains the applicaIon you want to run – e.g.: Tomcat ๏ When you subscribes the PaaS will spawn an instance from that image ๏ It will assign a load balancer and gives you re an IP to access ๏ When the load increases the PaaS will spawn another instance and assign it to the same load balancer
- 8. What is WSO2 Private PaaS ๏ ๏ Provides WSO2 Carbon servers as cartridges ๏ Instance level mulI-‐tenancy ๏ Closely integrates with the Stratos tenants ๏ Billing and metering ๏ 8 Based on Apache Stratos(IncubaIng) Centralized Log processing
- 9. Why WSO2 PaaS 9
- 10. Extensible via Cartridges/Polyglot ๏ ๏ WriIng a new one is trivial ๏ Load balancer itself can be a cartridge ๏ 10 We ship number of cartridge types Plug-‐in your own load balancer
- 11. Auto Scaling ๏ ๏ Write scaling rules using a policy language ๏ Or use the default ones ๏ 11 Set you scaling parameters Watch your applicaIon scales
- 12. Supports number IaaS es/Polyhost ๏ WSO2 private PaaS support number of IaaS es. ๏ EC2, OpenStack, Vcloud to name a few 12
- 13. Cloud BursIng ๏ Enterprises do capacity planning ๏ AllocaIng resources generously would solve the issue, but not the most wisest of soluIons. ๏ It is possible to extend the my private cloud to protected public cloud infrastructure (IaaS) 13
- 14. Make the Most out of MulI-‐tenancy ๏ ๏ Tenancy at the container level – LXCs and VM instances ๏ Tenancy at the applicaIon level – mulI-‐tenant cartridges ๏ 14 PaaS level tenancy One tenant model across the plaTorm
- 15. Orchestrate using puppet ๏ A base VM image gets provisioned by puppet ๏ All the default shipped Cartridges are provisioned using puppet ๏ Push updates and applicaIon patches 15
- 16. The REST API ๏ ๏ Use Curl to perform operaIons ๏ Use the CLI tool ๏ 16 REST API Use the web-‐based management console
- 17. The API 17
- 18. Architecture 18
- 20. Architecture 101 ๏ ๏ Common bus – Any JMS compaIble message broker. WSO2 MB is preferred ๏ Plug in your own load balancer – Stratos LB and HA Proxy supported at the moment. ๏ 20 JCloud abstracIon for IaaS es. Cartridges are VM images that runs on an IaaS.
- 22. Cartridges ๏ Bring your applicaIon to cloud ๏ Can be a applicaIon cartridge/ framework cartridge such as tomcat ๏ Cartridge is dependent on the underlying IaaS ๏ Actual unit of execuIon VM Cartridge Application/Framework LXC Cartridge Application/ Framework Stratos Agent Stratos Agent Guest OS Host OS 22
- 23. Auto scaling ๏ ๏ Policy language to define scaling rules ๏ Bring in your own scaling factor to the framework – no code changes required ๏ 23 Make use of real Ime events Deployment policies – where to spawn my instance
- 24. Auto Scaling ๏ ๏ All the enIIes publish their runIme events to CEP ๏ CEP aggregates them and coarse grained events get pushed in to auto scalar ๏ 24 WSO2 CEP as the event aggregator Auto scaling rules act upon them.
- 25. Cloud BursIng ๏ ๏ Spawn new instances in public IaaS only if run out of on premise resources ๏ 25 Way of defining deployment policies Good for seasonal load handling
- 26. How You can Extend the WSO2 PaaS ๏ ๏ Deploy over your preferred IaaS ๏ Write agents that publish your very own scaling parameters ๏ 26 Bring in your own cartridge types Write scaling rules and CEP rules
- 27. Mix and Match ๏ ๏ Bring in your own event processor ๏ Plug your own load balancer ๏ 27 Use your preferred message broker Integrate to your own dashboards
- 28. Cartridges – 4 Types ๏ ApplicaIon : WordPress , Drupal ๏ Framework – PHP, Tomcat, JBoss AS, Node ๏ Data -‐ MySQL ๏ Load balancer – HA proxy, WSO2 ELB Come up with your own cartridge, its not difficult… 28
- 29. We are working on… ๏ ๏ First Class LXC support ๏ SimulaIon environment based on LXC s. ๏ More control over IaaS assigned IPs ๏ More control over instance spin up locaIon – depends on the underlying IaaS ๏ 29 Composite applicaIons – dependency among cartridges MulIple network interfaces for cartridge instances
