Building a Cloud Native Platform with WSO2 Private PaaS

  1. 1. Last Updated: March. 2014 Committer and PPMC member Apache Stratos (incubating) Software Architect WSO2 Inc Lakmal Warusawithana Building a Cloud Native Platform with WSO2 Private PaaS
  2. 2. ** About the Presenter Lakmal Warusawithana Committer and PPMC member Apache Stratos (incubating) Software Architect, WSO2 Inc lakmal@apache.org / lakmal@wso2.com
  3. 3. ** About WSO2 ๏ Global enterprise, founded in 2005 by acknowledged leaders in XML, web services technologies, standards and open source ๏ Provides only open source platform-as-a-service for private, public and hybrid cloud deployments ๏ All WSO2 products are 100% open source and released under the Apache License Version 2.0. ๏ Is an Active Member of OASIS, Cloud Security Alliance, OSGi Alliance, AMQP Working Group, OpenID Foundation and W3C. ๏ Driven by Innovation ๏ Launched first open source API Management solution in 2012 ๏ Launched App Factory in 2Q 2013 ๏ Launched Enterprise Store and first open source Mobile solution in 4Q 2013
  4. 4. ** What WSO2 delivers
  5. 5. ** Business Model
  6. 6. ** ๏ Cloud Native platforms accelerates innovation, increases operational efficiency, reduces costs ๏ The key building blocks of the cloud native platforms are - service provisioning - load balancing - management - policy enforcement - auto scaling - monitoring, metering and logging - multi-tenancy - multi-cloud, cloud SLA and cloud bursting - control/governance - expandability Cloud Native Platform
  7. 7. ** ๏ Enterprise-grade Open Platform as a Service ๏ Build top of Apache Stratos (incubating) ๏ Stratos initially developed by WSO2 and donated to Apache Software Foundation ๏ Include all WSO2 products as cartridges ๏ Well tested in different solution architecture patterns with all WSO2 product cartridges What is WSO2 Private PaaS?
  8. 8. ** WSO2 Private PaaS Layered Architecture
  9. 9. ** Why is this architecture so important? ๏ Cartridge model enable bringing in even legacy apps into cloud ๏ Unified communication across components in the PaaS using message broker ๏ Centralized monitoring and metering with unified logging framework - ability to plug in BAM ๏ Ability to plugin any IaaS due to the use of jclouds API ๏ Ability to plugin any third party load balancer using message broker model ๏ Ability to plugin any third party health checking/monitoring framework WSO2 Private PaaS Architecture
  10. 10. ** How Scalable it is? ๏ In theory infinite - horizontal scaling - limited by resource (instance capacity) availability How Dynamic it is? ๏ Load Balancers are spawned dynamically - LB too is a cartridge ๏ In case of multi-cloud, multi-region, LB can scale per cloud/region ๏ Per service cluster LB Scalable and Dynamic Load Balancing
  11. 11. ** What is unique about Stratos/Private PaaS ๏ Cartridge based LB model ๏ Can bring any third-party LB - HAProxy, nginx - As easy as plugging into LB extension API Scalable and Dynamic Load Balancing..
  12. 12. ** What is it? ๏ Scaling algorithm can use multiple factors. such as - Load average of the instance - Memory consumption of the instance - In-flight request count in LB ๏ Capable of predicting future load - Real time analysis of current load status using CEP integration - Predict immediate future load based on CEP resulting streams Multi-factored Auto Scaling
  13. 13. ** Why should one care? ๏ Maximise resource utilization ๏ Easy to do capacity planning ๏ Dynamic load based resource provisioning ๏ Optimizing across multiple clouds What are the advantages? ๏ Make DevOps life easy ๏ More accurate capacity planning Multi-factored Auto Scaling...
  14. 14. ** What are the smart policies? ๏ Auto scaling ๏ Deployment Auto scaling policy ๏ Define thresholds values pertaining scale up/down decision ๏ Auto Scaler refer this policy ๏ Defined by DevOps Deployment policy ๏ Defined how and where to spawn cartridge instances ๏ Defined min and max instances in a selected service cluster ๏ Defined by DevOps based on deployment patterns Smart Policies
  15. 15. ** Why should one care? ๏ Can provide cloud SLA What are the advantages? ๏ Make DevOps life easy - help keep to SLA ๏ Make SaaS app delivery life easy - do not have to worry about availability in application layer Smart Policies
  16. 16. ** What MT model does it support? ๏ Container MT - virtual Machine, LXC, Docker ๏ In-container MT - within VM/LXC/Docker tenancy What is unique? ๏ Can have high tenant density What are the advantage of this model? ๏ Optimizing resource utilization - by sharing resource such as CPU, memory across tenants - low footprint, based on utilization/usage of the tenants app ๏ No need dedicated resource allocation for tenants Multi-tenancy
  17. 17. ** What is a Partition? ๏ Logically group IaaS resource locations ๏ Partitions are important to make application high availability ๏ Cartridge instances are spawned inside these partitions ๏ Partitions are defined by DevOps What is a network partition? ๏ Logical groups multiple partitions, that are in the same network ๏ Stratos will spawn Load Balancers per network partition ๏ Since LB instances and cartridge instances reside in same network, they can communicate using private IP addresses ๏ Used in deployment policies Controlling IaaS Resources
  18. 18. ** What are the advantages? ๏ Can controll - per cloud, per region, per zone, ...etc ๏ Can achieve high availability, disaster recovery ๏ Help for cloud SLA ๏ Control the resource utilization ๏ Help with geo based deployments - help comply with geo rules/regulations Controlling IaaS Resources
  19. 19. ** What is it? ๏ Expanding/provisioning application into another cloud to handle peak load. Why Should one care? ๏ Resource peak time can be off-loaded to third party clouds/resources What is unique about it? ๏ Can off-load to any cloud - Private, Public and Hybrid ๏ Easy to managed with the model of LB per busting cloud Cloud Bursting
  20. 20. ** What are the advantages? ๏ Make DevOps life easy ๏ Low TCO, and higher utilization existing dedicated resources Cloud Bursting...
  21. 21. ** What details are? ๏ Instance up/down time ๏ Each and every instances health status - application health, load average, memory consumption ๏ Application logs Why should one care? ๏ Centralize view for all logging, metering and monitoring What are the advantages? ๏ DevOps life easy - centralize log viewer - centralize dashboard ๏ Easy to throttling Logging, Metering and Monitoring
