Information regarding potential future products is intended to outline our general
product direction and it should not be relied on in making a purchasing decision.

Performance is based on measurements and projections using standard IBM
benchmarks in a controlled environment. The actual throughput or performance
that any user will experience will vary depending upon many factors, including
considerations such as the amount of multiprogramming in the user’s job stream,
the I/O configuration, the storage configuration, and the workload processed.
Therefore, no assurance can be given that an individual user will achieve results
similar to those stated here.

Simple: future migration with Liberty profile
There is no migration needed for Liberty configuration
• the same server configurations can be used with different
versions and service levels of the runtime
• set WLP_USER_DIR to shared configuration and apps
Existing features will not change behavior
• new feature ‘versions’ will be added and will contain all updates
and changes
Supported versions of Java (J2SE) will move forward
• Several of the Java EE 7 technologies require Java 7
• Java 6 will go out of support at some point
– WebSphere Application Migration Tool already has support to
identify J2SE 6 -> 7 changes needed by an application

Secure
Out of the box…
• localhost only, minimal ports opened
• no default userids or passwords
• remote admin always secured
Registries
• Simple registry in server.xml to get started
• Federated LDAPs or SAF for production
• also Custom User Registry
OAuth 2.0
• allows apps to delegate authorization to a third-party
37
Robust
Tried and tested components reused in Liberty Profile
Industrial strength Transaction Manager
Failover of HTTP Sessions via DB or WXS
Failover of Collective Controller via replica set
Disaster recovery is similar to Full profile
• Best practice is to have dual, independent collectives ideally in
separate data centers
