The document provides an introduction to the DataPower appliance. It discusses how DataPower simplifies SOA implementations through superior performance, security, and integration capabilities. It also explains that DataPower addresses the challenges of XML such as performance, security, and integrating legacy systems through hardware acceleration and offloading functions from application servers.

1. DataPower Introduction

2. DataPower SOA Appliance
An SOA Appliance…
creates customer value through extreme
SOA performance, connectivity, and
security.
 Simplifies SOA and accelerates time to value
 Helps secure SOA XML implementations
 Governs and enforces SOA/Web Services policies
DataPower SOA Appliances redefine the boundaries of middleware extending the
SOA Foundation with specialized, consumable, and dedicated SOA
Appliances that simplify and combine superior performance, hardened
security, and integration for SOA implementations.

3. Why an Appliance for SOA?
 Hardened, specialized hardware for helping to integrate, secure & accelerate SOA
 Many functions in a single device

Service level management, dynamic routing, policy enforcement, transformation
 Higher levels of security assurance certification

FIPS 140-2 Level 3, Common Criteria EAL4
 Higher performance with hardware acceleration facilitates security enforcement
•
Addresses the divergent needs of
different groups
– Enterprise architects, network operations,
security operations, web services developers
•
Simplified deployment and ongoing
management

4. What is DataPower ?
•
•
•
•
Provides the flexibility of software in a hardware footprint
Is quick to deploy – configuration NOT coding or programming
Typically takes days to integrate NOT weeks or months
Is a 1U 19” Rack Mounted appliance
–
•
•
Looks like a router
Has minimal components and has no stack of software. Consequently
DataPower is highly secure
As attack points are minimised
–
–
DataPower is undergoing accreditation to Common Criteria EAL4
This is globally recognised check by an impartial third party that warrants the security claims
made by IBM

5. What Does DataPower Address ?
•
•
XML is the language of Web Services and SOA
XML is pervasive – in a matter of years, it will fuel every application, device, and
document found in enterprise networks
•
XML challenges
– XML is very ‘Verbose’
• XML is bandwidth intensive
• Has a direct impact on Application Server performance
• XML processing requires significant processor cycles and memory
resources
– XML is effectively ‘Human readable’ Text
• It has no native security mechanisms
• It is readily understood and vulnerable to interception
• Security can be implemented on the application server but this is additional
XML processing and adds to the performance problem
– SOA is not just Web Services and XML
• Customers need to integrate existing legacy systems, messaging formats
and protocols into the SOA architecture.
• The ability to ‘transform’ legacy systems into the XML format is needed.
5

6. What Does DataPower Address ?
•
XML Performance
– How ? – by offloading XML processing from the Application Server to
DataPower in optimised hardware
– Thereby greatly reducing the required number of Application Servers
•
XML Security
– How ? – by offloading XML security to DataPower
– Provide standards based security – WS Security
•
Integrating XML and legacy systems
– How ? – by using DataPower to transform XML to legacy message
formats and protocols e.g
• XML < > Cobol Copybook (brings a Mainframe into SOA
Architecture)
• XML > HMTL (renders HTML content to Portal very rapidly)
• XML < > MQ Messaging
All of this is done at WIRESPEED

SSL is key
Use management/security platforms
Manage your identities
You may need PKI
Trust (Really) Your Partners
Use OTS Web Services with Caution
Monitor and Control
“Therefore, enterprises should
investigate tools such as security
gateways, SSL concentrators and
accelerators, and wire-speed SOAP/XML
inspection hardware.”

16

17. The ESB Cost Explosion - background
A significant and growing problem with bus installations around the world.
In medium to large organizations
running significant transaction volumes,
the footprint of their ESB becomes very
large and expensive, very quickly.

18. The ESB Cost Explosion – Root
causes
1. The resource requirements of today’s services (mostly XML-based)
–
Software mediation solutions written on general-purpose platforms require shocking
amounts of CPU and memory to process messages and perform the basic bus
functions:
• Message Parsing and Interpretation
• Message Transformation
• Message Routing
2. The minimal headroom purchased because of HA requirements.
–
Companies quickly use up extra capacity purchased initially in order to maintain high
availability for this critical part of their network.
Nevertheless the problem is often still hidden by the HA deployment initially
Companies are often taken by surprise by how quickly they “hit the wall”
–
–
It doesn’t take much!
•
•
At somewhere between 20-60 TPS the infrastructure needs to be at least doubled.
you don’t have to be a F500 company to get hit
18

19. The ESB Cost Explosion - Solution
The DataPower module, deployed in an Architected ESB Federation pattern, is designed to
bring the “commodity” work of an ESB to the network layer.
SOA Network Infrastructure
History tells us that selecting universal, repetitive
functions and moving them to purpose-built
appliances reduces solution costs, both in terms of
increased performance / reduced processing costs,
and reduced complexity of deployment (network
devices are configured, not coded).
