Analysts suggest that Services Oriented Architecture will be a key tool for enabling change and alignment between business and IT
Top Challenges in Managing IT
Source: AMR Research, 2005
Top Expected Benefits of Services Oriented Architecture
Integration
Takes too long for IT to respond to changing requirements
Can’t configure business processes as needed
Faster and more flexible reconfiguration of business processes
Cost of managing IT is too expensive
Too hard to get ROI from upgrades
Decrease of operational costs of information technology and business processes
SOA is a strategy for designing software that helps eliminate the distinction between business processes and the technologies that enable them.

A Services Oriented Architecture (SOA) allows you to expose key IT capabilities and make them available in new ways
…and breaks them down into services…
These services can be integrated and used to build new capabilities…
A service-oriented architecture (SOA) is an architectural framework that takes business applications…
…supporting new functionality from within your current portfolio or from your extended value chain.

Partner Service
A bank has multiple systems for its various mortgage products and
processes
These systems can be broken down to expose the basic services they perform, such as submitting a
loan application and calculating interest rates
The services can be re-arranged to offer new products, such as a
hybrid credit product that combines features of a fixed and adjustable
mortgage, and a web portal that offers access to all credit products

IBM Global Services
There are two forces behind SOA that differentiate it from previous architectural approaches
1. Maturing technology standards (web services) are the game changing aspect that allow for a new level of interaction and provide for a common standard that supports:
– New component development– Transformation and integration of existing applications– Package integration
2. A new paradigm shift designing software as linked services changes the way software is designed and developed
– Software developed and integrated by linking defined services Services exposed from your existing, company portfolio of applications Services exposed from new applications you are building Services exposed from your partners systems or systems in your value chain
– Called services orientation, this thinking enables a tighter alignment of business and technology.
Businesses are experiencing tremendous benefits as they put SOA into practice, such as increased revenues, decreased costs, and enhanced flexibility

IBM Global Services
SOA Introduces Performance Challenges
Measuring performance across organizational boundaries can be more difficult than in siloed applications
Response time estimation is more challenging in a more distributed environment– Performance costs can be difficult to predict– Performance testing an SOA application requires the use of new techniques
Increased requirement for XML processing may impact performance
17 www.ibm.com/soa
IBM Global Services
Performance in SOA systems should be a combination of performance engineering and performance management
SOA-based applications can change the way an infrastructure performs
– XML message transformation, location, message size, frequency– More complex applications and transactions
Each of the components should be used to build a performance budget, transaction models and use cases
Middleware and server sizing need to be done with the application teams
– How many, how available, virtualized, system platform
Don’t forget about security overhead– Authentication, Authorization, Encryption
Performance Should Not be an AfterthoughtIt Should be Engineered into the Solution
18 www.ibm.com/soa
IBM Global Services
SOA Performance Testing Concepts
Test SOA applications throughout the development lifecycle
Test tools must be separate and external to the SOA environment
Use multiple diverse datasets that are representative of an SOA workload
Stress test the solution to detect latency issues
Run tests in a comparable environment to the deployment environment
Use multiple test tools – similar results from multiple test tools using identical data sets validates the tests
19 www.ibm.com/soa

Visualization of server resource
data
Validate system scalability– Workload modeling for automated
generation of test clients – Automated generation of
performance tests– Real-time reporting of server
response time and throughput
Isolate performance bottlenecks and resolve problems
– Monitoring support for services across multiple platforms
– Collection and visualization of server resource data – root cause analysis
SOA Performance Testing and Problem Analysis Tools
20 www.ibm.com/soa
IBM Global Services
Composite applications span technology and platform boundaries
Can be difficult to identify and isolate performance bottlenecks
Use lightweight instrumentation that can be dynamically configured to proactively identify performance problems
Use industry-standard ARM-based instrumentation to isolate the problem

ITCAM for Response Time Tracking
ITCAM for WebSphere
21 www.ibm.com/soa
IBM Global Services
The SOA performance model should be created and maintained throughout the lifecycle as the application is built
Performance testing needs to obtain sufficient metrics to validate that services meet performance expectations
Use established techniques to meet SOA performance requirements
Design, test, and retest to confirm that non-functional requirements are met
Implement an integrated solution that will automatically monitor, analyze and resolve response time problems
Consider dedicated network appliances to optimize and accelerate XML parsing and security processing
Guidance for SOA Performance
22 www.ibm.com/soa
IBM Global Services
There are an increased number of components in an SOA infrastructure, so test rigorously for availability
Create failover plans based on criticality of applications and services
Take advantage of established availability techniques– Each component requires its own availability architecture – Leverage capabilities like Workload Management, High-Availability Manager,
Deployment Manager, etc. Some components may require both hardware and software
clustering– Databases, enterprise messaging infrastructure, SOA appliances

Key Elements for Managing Services
1. The runtime environment – this is where messages are routed, secured, transformed, filtered and logged
2. The management server – aggregates the data from all of the endpoints and runtimes and sends configuration changes based on policy
3. The registry – stores meta data about services and policies

Improve MTTR (Mean Time to Resolution)
– Accurate application maps show you what is important
– Find the “Last Change” before a problem shows up– Simplify impact analysis
Configuration Drift– Notice when Configurations change and notify
operations– Keep “bit-rot” from impacting operational readiness

SOA Security Considerations
SOA introduces raise additional security issues– How do we identify and authenticate the service requester? – How to we identify and authenticate the source of the message?– Is the client authorized to send this message? – Can we ensure message integrity & confidentiality?– How do we audit the access to services?– How do we leverage Web services security standards?– How do we propagate identities with trusted service providers?
XML Web services may expose backend systems in unintended ways
SOA security may require multiple layers of enforcement – perimeter, gateway, app server, application
Traditional security devices do not secure XML/SOAP

SOA Implications on Non-functional Requirements
Infrastructure and Services security—How do we secure services, and how does this affect my overall infrastructure security goals?
Systems performance—How will XML transformation, between our legacy and distributed systems, affect application performance?
Availability/Recoverability/Reliability—What happens if one of my services is unavailable? Where are my applications located, and what are my dependencies between my business partners? How do I restore and resynchronize any associated data and metadata to keep data consistency?
Scalability—How do I ensure that the infrastructure will grow in line with volumes?
Manageability—How do I manage my services to tell whether they are available and performing? How do I validate my applications and ensure that they are meeting business goals?
40 www.ibm.com/soa
IBM Global Services
Design the application without looking at the infrastructure
Just leave the infrastructure “as-is”
Have the application and infrastructure groups not talk to one another
Over-engineering the IT infrastructure
Not updating any of the processes that are involved with the new applications
Not focusing on the BASICS of good IT infrastructure and application development

The role of IT Technical Architecture in SOA Projects: “An Elevator Pitch”
The success of an SOA Project also requires the planned satisfaction of new
requirements regarding Performance, Availability, Service Management, Security, and Virtualization on the
underlying development, management, and production technical architectures.
Moreover, an Enterprise SOA Architecture will require a well designed integration
and connectivity architecture, with specific components, like the ESB, a
BPM, and the services Registry; they are now a key part of the IT Infrastructure.
