Agenda

• Cloud Computing• PaaS and Java EE• PaaS implications on application deployment• Design Model• Resources

Cloud Computing

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

What’s new?

(+) Above the Clouds, Armbrust et al, UC Berkeley, 2009

Cloud Computing

On-demand Self-Service

Broad network access

Resource Pooling

Rapid Elasticity

Measured Service

Essential Characteristics

(*) NIST Definition of Cloud Computing – 800-145

Cloud Computing

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

Deployment Models

Cloud Computing

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)

Service Models

Resources

PaaS and Java EE

Common programming model for enterprise developers

Runtime handles application’s infrastructure concerns

Declarative resource references

Scalable (scale-out) component models

Java EE design principles and capabilities

PaaS and Java EE

Enhancements– New Roles for PaaS– Services as first class citizens– Multitenancy

Evolution, not a revolution!

PaaS Implications on Deployment

Simplified PaaS Application Deployment• Single-click, self-service, “push to cloud”

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 versioning

Services Management

Scalable virtualized on-demand environment– Support multiple cloud deployment models

• Public, Private, Hybrid

– PaaS Provider decoupled from IaaS infrastructure– Multi-tenancy

Virtualized runtimes

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 Services

Scaling and Operations

Terminology

Service

ServiceType– Java EE, RDBMS, HTTP Load Balancer etc.

Services – scope and lifecycle– Provisioned Services

• Application scoped• Shared

– External (a priori ) services

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 configuration

Design Model

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 archive
