About IBM Websphere Data Power

 IBM WebSphereDataPower SOA Appliances are purpose-built, easy-to-deploy network devices that simplify, help secure, and accelerate your XML and Web services deployments while extending your SOA infrastructure.

For security we have – Firewalls, Virus Scanners, Proxy Servers etc. Then we have Mainframes, Databases, server clusters where services are hosted. Also there will be a server that is used for authentication. Given all these h/w and software, the cost to install, configure, maintain and operate any of these components are going to be huge. Not to mention that we have XML, Copybook, flatfile and databases. This would need  data-transformations. Additional cost on h/w and s/w for that.

Datapower Integration Appliance XI50 in itself has the capabilities of  XS40 and XA35. In addition to that, it provides or has 

• Any-to-any transformation engine
• Transport bridging
• Integrated message-level security
• Lightweight message brokering

Which means that with all these capabilities you got yourself an ESB.
