CASTLE IN THE CLOUDS

JAN SNEL – FLEXIBLE BUILDING

• No up-front investment• Scale Up – quickly expand into new units• Scale Down – have units removed when no

longer required• Offices can quickly be relocated to a different

site• Building maintenance is taken care of• Day to day monitoring and security

surveillance• Standardize on office layout and interior• Additional office units are available in case of

emergencies (fire, flooding, …)

THREE BROTHERS…

THE THREE SNEL BROTHERS

Piet Jan Simon

THE SNEL BROTHERS

• Piet Snel – provides the plot on which to build (including electricity, water, sewerage,…)– So you can build your own units if you want to

• Jan Snel – provides turn-key office space from flexible building units and office furniture– On his brother’s plot or on your own plot

• Simon Sneller – provides the services that your staff would have provided from the new office– You do not have to hire & train (& fire) people– Perhaps they sit in Jan’s building, possibly on

Piet’s plot. Or in some unknown location somewhere.

• You do not have to care!

WEBLOGIC IS THE CLOUD PLATFORM

• Oracle Database and WebLogic Server (with selected FMW components) provide PaaS in the Cloud

CLOUD PROMISES AND CHALLENGES• Quick start up• Flexible (agile) scalability• Performance and Availability• Low(er) TCO• Small initial investment• Consolidation and Standardization• Professional, centralized administration

services • Security and Compliance

SCALABILITY WEBLOGIC: SCALE OUT WITH CLUSTERING• Scale out by

• Adding server instances to cluster on existing machine

• Adding machines to cluster to host incremental server instances

• Without interruption of service• Scale Down works in same way (except for

licenses)WebLogic

WEBLOGIC SCALABILITY WITH ORACLE REAL APPLICATION CLUSTERS• Oracle RAC installation = Standard Oracle database

• RAC coordinates access to shared data for consistency, integrity

• Add nodes to RAC 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 RAC node

DO NOT DO IT…MORE OFTEN THAN REQUIRED

• If it has been produced before…– Reuse before re-produce!

• If it has been shipped before…– Reuse instead of re-ship

• … provided it is still freshWeb Browser

DO NOT DO IT…MORE OFTEN THAN REQUIRED

• Save on network trips, context switches and tiers to cross

• Save on ‘reproducing’ same results

ACTIVE CACHING IN WEBLOGIC WITH ORACLE COHERENCE MEMORY GRID• Add/remove nodes dynamically• Scale linearly to hundreds of nodes• Get extreme reliability through redundancy• Achieve high performance

• Data resides closer to application

• Parallelization• Write behind• Reuse instead of

reproduce• Get continuous availability

• Seamless session fail-over - all nodesshare session state through the cache

• Newer version of application deployed side-by-side with older version in same JVM

• Clients already connected continue to be served by older version

• New clients connect to newer version

• Test versions before opening up to users

• Rollback to previous versions• Automatic retirement –

graceful or timeout• Very similar to Edition Based
