DATAPOWER

Overview of the DataPower appliance:

With SOAs, composite applications are created that are comprised of reusable,

loosely-coupled service components. The technical foundation of an SOA is in the support for

the XML and Web services built on top of it. By using SOAP, SOA clients can invoke services

(RPC-style) without explicit support for a wide variety of transport protocols and message

formats. By having a SOAP facade in front of an existing service, virtualization can occur

where clients invoke a virtualized version of the underlying service. It eliminates the need to

understand intricate details of the service’s implementation.

Three products of data power family

1 . XA35 (Green )

2 . XS40 (Yellow )

3 . XI50 (Blue)

XA35

1 . Its primary function is to make XML “Go faster”.

2 . In XA35 “A” Stands for Acceleration.

3 . Data power is an optimized cashes and dedicated SSL hardware to process XML at near Wire speed.

4 . XA35 is a strong appliance, but it has a limited security .

5. It doesn’t have XML thread protection or Encryption , Digital signature capabilities.

6. Because of these reason it sits behind the DMZ , in a trusted zone and process the XML files.

A popular usage is to receive XML responses from backend servers and transform those into HTML before continuing the response to the client. It has full SSL and SNMP capabilities to fit into the network infrastructure.

XS40

1 . The Data power XS40 is called security appliance.

2 . Its yellow color represents caution or Yield. XS40 “S” Stands for Security.

3 . This is found in DMZ zone, as  its Security capabilities are excellent.

4 . XS40 has all the capabilities that XA35 has and some extra features too.

• Encryption and decryption
• Digital signature creation or verification
• AAA (Authentication , authorization and auditing)
• Full XML Threat protection

XI50

1 . XI50 is an excellent product in the market.

2 . In XI50 , “I” stands for integration

3 . Due to its integration capabilities it is often found in the backend private network, functioning in an ESB capacity but is just suitable for the DMZ.

4 . XI 50 has all the features of (XA35 +XS40+Additional features)

• Web Sphere MQ client option
• Web Sphere JAVA MESSAGE SERVISE (JMS) jet stream  protocol connectivity.
• TIBCO Enterprise Message Service (EMS ) Connectivity.
• IBM  IMS connect client.
• Database option (DB2, Oracle, SQL Server).
• Optimized runtime engine for non-XML  Transformation.
