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, …)

Incorporation

Or no Incorporation

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)

WebLogicScalability 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 fresh

Do not do it…More often than required

Save on ‘reproducing’ same results

Scale linearly to hundreds of nodes
Get extreme reliability through redundancy
Achieve high performance
Data resides closer to application

Reuse instead of reproduce
Get continuous availability

Availability: Zero down time application (re-) deployment
Single Java VM
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 Redefinition in Database 11g R2
