  • 1. Liferay and CloudCloud portals, Amazon and more . . .Miguel Ángel Pastor Olivar
  • 2. A little bit about meWorking at the "infrastructure" sideCloud computing and distributed systemsInterests in concurrent and distributed programming.Functional programming advocate!Scala, OSGI and AspectJ enthusiast. Erlang aficionadoEmail: miguel.pastor at liferay dot comTwitter handler: miguelinlas3
  • 3. AgendaThe status of cloudDo I really need cloud?Liferay deployment architectureGoing devops. Help ourselves with great tools
  • 4. The status of cloudsHave I already said Open Source?
  • 5. Cloud portal, value add Abstraction API Orchestration Service HypervisorNetworking Compute Storage
  • 6. Do I really need cloud?
  • 7. Do I really need cloud?Trending topicOur CIO says we need to be thereFaster time to marketAccess to pooled resourcesHybrid IT
  • 8. 5 main features of cloudOn demand self serviceBroad network accessResources poolingRapid elasticityMeasured service
  • 9. Liferay and CloudDeploying Liferay at Amazon Cloud
  • 10. 44 Load Balancer 3 3 Web Web Server Server 1 1 App App Server Server App Tier 2 2 AZ-1 AZ-2
  • 11. 11 The application tierAmazon Compute Service (EC2)Important! compute units != CPU != coreCluster Compute Quadruple Extra About 33.5 EC Compute UnitsEBS optimized could be a good allyTake account of virtualization overhead in your provisioningplanning
  • 12. 1 1 The application tierUse AMI to easier and quicker scaling.EBS backed are preferred (personal opinion).Tune connection pools, Java heap, garbage collector, … Same than physical deployments
  • 13. 1 1 The application tierUse JDBC_PING for Jgroups Discovery mechanism Clusterlink, cache replicationS3_PING Alternative“Documents and Media” application S3 storage
  • 14. 2 2 The database tierTwo approaches RDS service versus own managed database serverDepends on your needs and requirementsRDS is extremely easy: completely managed Easy to scale ReliableAbsence of low level control: tunning, optimizingLimited set of databases: Oracle, MySQL and SQL Server
  • 15. 3 3 Load balancingAlternative to HAProxy/ApacheScales based on incoming requestsEC2 instances health detectionSupport for sticky sessionSupport IPv4 an IPv6
  • 16. 3 3 Load balancingCreate a new load balancerSelect the protocol: HTTP(s), TCP, SSL or CustomConfigure health checksSelect the instances behind the load balancer
  • 17. 4 4 Monitoring our systemUsing the Cloud Watch serviceNo additional software requiredReal time monitoringSet alarms, view graphs and statisticsCustom metricsCombine it with the auto scaling service
  • 18. How can we achieve this?A proposed solution
  • 19. Which is our goal?Create any kind of environment Development, testing, production, …Do it very quickly!Dynamically and customizableDo it on a cloud infrastructure Don´t get tight to AWS
  • 20. Additional challengesBe able to scale dynamicallyManage “non-software” components Network configs App level configs System configs
  • 21. Proposed tools
  • 22. Multi cloud library written in Java + ClojureAbstraction layer over resource managementCoding our infrastructure management Port between different providers
  • 23. PalletProvision nodes with software and configurationVerifies nodes and services are working fineOperates the services in nodesUses JClouds under the hood Creating and managing nodes
  • 24. Why Pallet??Integrates perfectly with the infrastructure managementScalable programming model (thanks to Clojure)No central serverNo required agents on nodesAll node configuration is done via ssh + scripts (generated)DSL for generating scriptsTesting
  • 25. ClojurePallet is built on top of ClojureClojure is a JVM based Lisp dialect Integration with Java and awesome concurrencyHigher level of abstractionBecoming extremely popular (many books have been writtenrecently)
  • 26. This is very cool but . . . How!?
  • 27. Cloud infra-structureI want a bunch C ELB ELBHow is itstuff Apply going? of nodes l JClouds s o Liferay JCloud Pallet u Liferay Liferay Pallet d Liferay Liferay Liferay Pallet A P I Database Database Database Database Database Database
  • 28. Configuration management
  • 29. Managing nodes
  • 30. Question & Answers?
