Considerations for Evaluating & Building Cloud

• Security & Compliance: Loss of Control

• Reliability: SLA Compliance

• Availability: Provider guarantee

• Performance: Meet business requirements

• Manageability: Roles, responsibilities

Customer Concerns

• Scalability to pre-empt premature investment

• Elasticity for business agility

• Built on products from trusted vendor

• Efficient, Integrated

• Development Platform

• Build/Deploy/Provision Tools

• Management Framework

WebLogic: Scale Out with Clustering

• Scale out by

• Adding server

instances to cluster on

“We rely on Oracle WebLogic Suite to make sure that we have the reliability and

scalability that we need to keep growing the business. ”

- Doug Mutart, Chief Architect, GM OnStar

WebLogic Scalability with Oracle RAC

• Oracle RAC installation = Standard

Oracle database

• RAC coordinates access to shared

data for consistency, integrity

• Add nodes to cluster easily

• No need to partition data

• Horizontally scale database tier

as usage grows

• By adding RAC nodes, storage,

or both

• Scale WebLogic by adding data

source that maps to new node

Oracle Coherence Benefits

• Add/remove nodes dynamically

• Scale linearly to hundreds of nodes

• Get continuous availability

• Get extreme reliability through

redundancy

• Achieve high performance

• Data resides closer to application

• Parallelization

• License as part of WebLogic Suite

Why High Availability?


Oracle WebLogic: Guaranteed High Availability

Myriads of High Availability Capabilities

• Inter, Intra-cluster session state replication to handle

failure

• Zero down time deployment to deploy new version of

application without interrupting work on older version

• Overload protection to detect, avoid recover from overload

conditions

• Automatic Server Migration to migrate managed servers in

case of imminent hardware failure

• Application Failover

• Load Balancing

23

“The business benefit of using Oracle WebLogic Suite is that we

increased availability tremendously” Peter Strickx, Belgium’s

Federal Government CTO

Why Reliability?


31

Oracle WebLogic: Rock Solid Reliability

Transaction Integrity

• Commit with all transactional objects

• Transaction termination only by client that created transaction

• Support for the Open Group XA interface

Reliable Messaging

• Reliable message delivery between applications distributed

across clusters, domains, server instances

• Message producers automatically attempt to reconnect

Integration with Oracle RAC

• Loss of a node does not result in downtime

• When RAC node fails, in-flight transactions redirected to

another node in cluster

What is Elasticity? Why Important? Basic Premise of Cloud Computing


• Elasticity

• Instantly bringing necessary

resource when you need it

• Instantly decommission when

you don't need it

• Applications expand/contract

on demand, across all tiers

• Application components grow

independently from each

other

• Adding computing resources

transparent to application

Urban Airship

• Powers world's most successful mobile apps

• Connected to over 90 million mobile devices

Mike Herrick’s (VP of Engineering) Blog

WebLogic Suite Delivers Elastic Capacity with Enterprise Manager


• WebLogic’s automated load balancing, failover

• Dynamic addition, removal of nodes: WebLogic, Coherence, OS…

• Automation of capacity adjustment at all layers

• Unified management of entire cloud infrastructure from a single console

• Summary


Develop Cloud Applications in Shortest Possible

Time, Lowest Total Cost

36

Choose between Open Source, Commercial framework

• JDeveloper: Build rapidly with declarative, model-driven approach

• TopLink: Streamline storing/retrieving objects to/from data stores

• Easily manage Spring apps via Spring admin. console extension

• Access Eclipse community tools, plug-ins, products

• Use Application Development Framework (ADF) for Struts, JSF

based framework for rich Web apps

“The application server has to be friendly in a development environment and

WebLogic is that. (Our developers) literally have no problems with it. And it's

very well-integrated with our development tools.

-- John Tumminaro, CTO, Obopay

unattended deployment

• Live Migration: Move VM from a server to another in seconds

• Automated procedure to scale out (in) RAC clusters

Compliance Tracking • Comprehensive asset tracking, change detection

• Configuration comparisons, drift analysis to track changes,

adhere to baselines and compliance standards

• Alerts for out-of-policy, unauthorized changes

Visibility, Transparency • End user monitoring: Click-by-click user history, problems

• Manage Many-as-One: View, perform administrative tasks

for groups rather than individual components

• Metrics, Chargeback Reports: Automatic, Immediate
