An ESB is a standards-based integration platform that combines messaging, web services, data transformation, and intelligent routing to reliably connect and coordinate the interaction of significant numbers of diverse applications across extended enterprises with transactional integrity.

Performance-tuning your application should first include the most obvious settings,
such as the best fetching strategies and use of proxies.

This is an article about how to tune our hibernate settings to gain the best performance and prevent vulnerable problems.

- Definitions
- Example: Authentication Service
- Authentication Web Service
- Authentication Client
- XML Transformation
- RESTing Without JAX-WS

There are good reasons to support this illusion. When a client requests a service, it should make no difference if the service runs on a single server or across a number of servers. The clustering abstraction provides you with a clear route to improving the performance and scalability of your applications, albeit with increased administration of hardware and network resources. WebLogic’s clustering offers three important benefits:
Scalability
A solution that allows you to create additional capacity by introducing more servers to the cluster, thereby reducing the load on existing servers.
Load balancing
The ability to distribute requests across all members of the cluster, according to the workload on each server.
High availability
A mix of features that ensure applications and services are available even if a server or machine fails. Clients can continue to work with little or no disruption in a highly available environment. WebLogic achieves high availability using a combination of features: replication, failover, and migratable services.
