The core infrastructure components in the SOA ecosystem

, performance and testing

Virtualization


For SOA infrastructure, the magic happens in the middle layer

Knowing which product to choose depending on the business requirements- How much brokering? How much security? How much transformation?

- How much availability? Different vendor – new high-availability scheme

- Message transformation? Client standards?

- Which hardware platform? How will the applications connect?

Understand the technical requirements and future state of the infrastructure before deciding on which SOA middleware component

- JMS? MQ? HTTP? EIS? XML security? WS-standards?

- SOA infrastructure requires close ties with the application teams

SOA middleware


SOA management is a critical enabler for the wide spread adoption for SOA

In the SOA world, application management becomes more complex and requires additional tooling to uncover application performance

Involve monitoring and measuring the performance and availability of web services (components), and a more complex monitoring for business functions

Tools such as ITCAM for SOA can help uncover how the applications and services are working together vs. standard CPU, memory, etc.

These SOA tools should integrate into part of the existing enterprise systems management (ESM) infrastructure

SOA management is about using what exists today and integrating what’s new tools to manage and monitor the SOA communications

SOA management


The applications went from existing on a single box to possibly existing on multiple servers in different locations!

- Services can exist everywhere and the transactions can be long running

- Applications need to be “availability” aware in case a service within the workflow is unavailable

Plan for the unexpected!- What are the non-functional requirements? What systems are you using?

Distributed? Mainframe? Where are they located? How will they be accessed?

High-availability in the SOA world can include the entire environment- The holistic environment, downstream dependencies, external services, virtualized

applications, single-points of failure all become part of the solution

SOA applications can jeopardize availability service levels- How well do you understand how the SOA-based applications work?

- Many new components, many dependencies, who understands the big picture?

SOA availability

High-availability in SOA world


Performance in SOA systems should be a combination of Performance Engineering and …

The additional flexibility afforded by SOA brings significant performance engineering challenges

Messaging is key to composite application performance

Response time estimation is more challenging, especially for complex components such as the ESB

Significant new challenges faced when performance testing an SOA application

The performance model should be created and maintained through out the project lifecycle as the application is built

Performance Engineering


… Performance ManagementSOA-based composite applications while offering flexibility for business/IT alignment introduce management challenges resulting in difficult questions that organizations must address

“Design to Manage is key …. SOA-based tooling enables development to create application packages capturing the knowledge (metadata) required by operations to better manage the application

Techniques such as pool / thread funnelling can help ensure that the infrastructure is not overwhelmed by unknown loads

Caching strategy should be part of the design

Keep the number of hops through the application components to a minimum

Careful consideration should be given to the number of times the data has to be persisted

Performance Management


SOA testing strategy is a bottom-up certification

SOA adoption introduces new and unforeseen challenges with security integration, identity and security management

SOA and systems security is big undertaking- How much security is enough?

- Authentication / Authorization, Message Encryption, XML Firewalls

- Leave SOA security to the experts but be informed!

- Work with the SOA application teams to understand the requirements

SOA security is a part of the bigger security solution- SOA security is just another tool in the Infrastructure Architecture toolbox

- How should the SOA security integrate into the overall security solution?

There are many parts of SOA security- XML Message Encryption

- Authentication / Authorization

- Integration with Single-Sign-On (SSO) Systems

- WS-Security standards

- SOA application security programming

SOA security


Balancing the performance of the application and the infrastructure

Are hardened security devices – Penetration tested

Are purpose built embedded systems – Optimized for SOA processing

Are highly configurable – Simplified SOA architecture

Are able to process all formats of data (XML and others)

Are standards based – Work with existing infrastructure

Use to address XML processing performance issues

Use to augment standard infrastructure security

Can be used for light-weight message transformation

Not a general purpose server with some pre-loaded software

Are Not running a full standard operating system

SOA appliances


SOA and Infrastructure Virtualization Synergies and Alignment

Similarities SOA

Horizontal integration

Break down application silos but reusable services shared as a single logical asset

Break down infrastructure silosbut resources managed as a single logical infrastructure

Agility Services quicker available. Decomposition helps meeting business applications needs

Resources quicker deployed.Insulation layer helps adding resources to support business

Enabling flexibility

Supports dynamic application construction and service-to-service communication

Storage virtualization is a great example of the flexibility of infrastructure virtualization

Complex interdependencies are removed

Simplification

Virtualization

Users or applications do not dependent on any given physical resource

Virtualization


Making SOA better: infrastructure virtualizationSOA is dynamic resource utilization per se, this requires flexibility in resource management and virtualization, and orchestration.

Virtualization

•Separate Systems•High Complexity•High Unit Cost

•Low Utilization•Slow Response

•Improved efficiency•Shared resources•Reduced complexity•Easier administration•Managed capacity

•Peak utilization•Lower unit cost•Fast response rate•Dynamic Infrastructure

Business services flexibility can result in an unmanageable stress of some components, putting business results at risk

A requirement for a flexible and adaptive IT infrastructure is the consequence


SOA projects must deal with the transformation of the functional architecture AND the operational architecture

IT and SOA infrastructures co-habitationToday’s infrastructure must provide the same services for ALL applications

A well-designed SOA infrastructure is a mix of current and SOA infrastructure technologies

SOA and traditional applications don’t exist outside of one another


Solid SOA infrastructures are built from or updated from solid IT infrastructures

SOA applications play a specific role in the overall application

A unified infrastructure and application team has to built the solution in unison

Application awareness and middleware experience within the infrastructure teams are both critical skills

SOA infrastructure best practices


SOA infrastructure “anti-patterns”!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
