Program Agenda • Cloud Computing • PaaS and Java EE • PaaS implications on application deployment • Design Model • Service Orchestration • Resources6 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

Cloud Computing What’s new? • Illusion of infinite computing resources available on demand • Elimination of an up-front commitment by cloud users • Ability to pay for use of computing resources on a short- term basis (+) Above the Clouds, Armbrust et al, UC Berkeley, 20097 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

Cloud Computing Essential Characteristics • On-demand Self-Service • Broad network access • Resource Pooling • Rapid Elasticity • Measured Service (*) NIST Definition of Cloud Computing – 800-145 (Draft)8 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

Cloud Computing Deployment Models • Private Cloud – Operated solely for an organization – On-premise or off-premise • Community Cloud • Public Cloud – Access to general public • Hybrid Cloud – 2 or more clouds, Cloud Bursting (*) NIST Definition of Cloud Computing – 800-145 (Draft)9 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

Cloud Computing Service Models • Software as a Service (SaaS) • Platform as a Service (PaaS) – Deploy customer-created applications – Using languages and tools supported by PaaS Provider – No control of underlying cloud infrastructure – Control over deployed applications, hosting env. Configurations • Infrastructure as a Service (IaaS) (*) NIST Definition of Cloud Computing – 800-145 (Draft)10 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

PaaS and Java EE Java EE design principles and capabilities • Common programming model for enterprise developers • Runtime handles application’s infrastructure concerns • Declarative resource references • Scalable (scale-out) component models12 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

PaaS and Java EE Java EE 7: “Making Java EE ready for the cloud” • Enhancements – New Roles for PaaS – Services as first class citizens – Multitenancy • Evolution, not a revolution!13 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

New PaaS Roles in Java EE 7 • PaaS Product Vendor • PaaS Provider • PaaS Account Manager • PaaS Customer • Application Submitter • Application Administrator • End-User14 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

PaaS Implications on Deployment Services Management • Automatic Service Provisioning and Management – Service Orchestration • Automatic Service Dependency discovery • Service Provisioning and Association – Handle operational infrastructure concerns automatically • Network configuration, HA, Clustering, Load Balancing … – Application and Service deployment versioning18 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

PaaS Implications on Deployment Virtualized runtimes • Scalable virtualized on-demand environment – Support multiple cloud deployment models • Public, Private, Hybrid – PaaS Provider decoupled from IaaS infrastructure – Multi-tenancy19 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

PaaS Implications on Deployment Scaling and Operations • Automatic Scaling of Services – Scale to application’s needs – User-defined alerts and actions • Control over application hosting environment – Flexibility in choice of application services, framework – Rich service configuration – Shared services – Extensible runtime to allow new Services20 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

Service Orchestration One-liner Enable single-click deployment of a PaaS application through automatic service dependency discovery, service provisioning and service association27 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

Terminology • Service • ServiceType – Java EE, RDBMS, HTTP Load Balancer etc. • Services – scope and lifecycle – Provisioned Services • Application scoped • Shared – External (a priori ) services28 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

Specification of Service Metadata • Optional! – When not specified (vanilla EE app archives) • Orchestration Engine automatically handles discovery of service deps • Automatic wiring to default Service Templates – Metadata may be specified when: • Finer grain control of application environment desired • Application-specific Service configuration29 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

Specification of Service Metadata • Service Definition – Metadata used to provision and configure a Service • What : Service characteristics (functional and non-functional) → Template matching • How : Explicit Template specification → Template wiring • Service Reference – An application component’s dependency on a Service • Explicit : User-specified through deployment descriptors • Implicit and Discovered: Information contained within the archive31 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

PaaS Deployment Usecases Available now in GlassFish 4.0 • GlassFish 4.0 latest builds – PaaS Deployment/Undeployment – Application enable/disable – Elastic scaling of GlassFish Services43 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.

PaaS Deployment Usecases Candidate Features • Redeployment support with retain services • PaaS Application Versioning • Shared and External Services • Support for other ServiceTypes – MQ …44 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.
