The Challenges in Real Life ESB Deployment ScenarioThis presentation

discusses some of the key challenges that are typical for many deployment

scenarios of SOA workflow, process management, and orchestration solutions

using Enterprise Service Bus (ESB) solutions. In this session Frank Cohen,

author of FastSOA, the way to build performance and scalability into SOA and

CEO at PushToTest, shows the pitfalls that can severely inhibit the successful

rollout of an SOA project and how careful planning can minimize the likelihood

of a failed project. The presentation is based on PushToTest’s major study of

Java developer productivity in building applications using SOA methodology on

IBM, Tibco, Oracle and BEA platforms, see http://soakit.pushtotest.com. The

study finds Java developer productivity varied by as much as 49%. He will show

how an important aspect of avoiding these issues comes from planning and

conducting meaningful tests that cover most of the eventual use cases.See

http://www.pushtotest.com for this slide deck and additional details.

Agenda� PushToTest Community (Developers, Testers, IT) Tell Us:

� SOA Development Patterns Require Grid Approach To

Development and Operational Governance

� Too much deployment coding

� Need to understand service interoperation rapidly

� Oracle, IBM, BEA, TIBCO tools have big differences

� Study shows TIBCO offering lower TCO, better architecture, less

hassle over-all

� PushToTest continues tradition of Knowledge Kits

� Developer Journal, Implementation, Source Code, Build, Tests


5

SOA Promises� Reduced Costs from Component Reuse (Registry)

� Better Able to Achieve SLAs (Governance)

� Architecture for Modern Application Development

(Web 2, Enterprise 2)


6

Today’s Tools Deliver� Confusing Mix of Features, Functions, and Bugs

� Tools Demand Mix of Backgrounds, Skills,

Architectural Experiences

� Tools Do Not Play Well Together

� Huge Variations In Performance

(Due to Developer Decisions)


7

Service Virtualization� Too much code to deploy and manage

Service Virtualization White Paper

http://soakit.pushtotest.com


8

Service Composition� Maps Service Interdependency

� Reduces Maintenance Costs

� Increases Uptime


9

Tony Baer analyst� “PushToTest study points to one important fact:

developer productivity remains a major factor in

time-to-benefit, and it’s an area that most SOA

vendors have not paid adequate attention”

XML, SOA, and Performance

Core Concepts of Use Cases � SOA Application Construction and Deployment

� Service Construction & Enablement

� Service Mediation

� Transport, route & deliver

� Data transformation

� Management & monitoring

� Service Governance

12


Functional Requirements� Design Review

� Installation/Configuration

� Adapter Setup/Configuration

� Project Management

� Integration

� Service Construction

� Service Orchestration

� Deployment

� Security

� Policy Management

� Monitoring and

Management

� Change Management

� Performance

� QA

13


Use Case: SOA

Manufacturer Supply Chain

Service Oriented Order and Fulfillment

•Service creation

•Deployment

•Policy

•Registry

•Legacy integration (SAP & Siebel)

•Service Mediation

•Orchestration

14


The Use Case – Phase 1� Allocate Purchase Order

� Service from the financial services group to issue and track

purchase orders

� Service (.NET) features three methods: � Open new PO, Close a PO, Remove a PO

� SOAP over HTTPS

� Reserve Parts

� Service for warehouse just-in-time inventory control� Reserve inventory

� SOAP over JMS

� Conforms to the inventory control service's XML message schema.

� Price Purchase Order

� Assign price from price catalog in SAP23


15

Use Case: BPM + CEP

Developer Productivity TCO� ActiveMatrix + BusinessWorks

proven to require less time and

costs in actual side-by-side

product implementation

� 49% less time/costs vs. BEA

� 35% less time/costs vs. Oracle

� 22% less time/costs vs. IBM


18

Cost of Ownership� SOA Is About Reuse

� BEA increases cost of ownership by as much as 83%

� Oracle as much as 59%

� IBM as much as 43%


19

What Makes This Interesting� Moves Services Onto The Grid to benefit

from Operational Governance

� Orchestration and Repository for Enhanced Productivity

in Development and Production

� Graphical Integration Development

� Strong Interoperability: Platform, Message Schema,

Service Interface Independence

� On-Ramp for developers to understand and use

BPM and CEP productively


20

What Makes This Suprising� BEA, IBM, Oracle Retrofit SOA Into Established Platforms

� Requires Many SOA Skills To Be Successful

� SOA Requires Interoperability and Integration With Services

� BEA, IBM, and Oracle Struggle With Services and Business

Flows Built Outside of Their Own Tools

� BEA, IBM, and Oracle Require Multiple Tools to Get From

‘Here’ to ‘There’

� We Found “Blocker” Bugs in BEA, IBM and Oracle Shipping

Products

� Bugs Are Significant Enough to Impact TCO

21


Development Skills� BEA requires Java, XQuery, XSLT, EJB, BPEL, XML,

WSDL and their GUIs

� Oracle requires Java, SQL, EJB, BPEL, SDO, XML, and

proprietary deployment descriptors

� IBM requires Java, SQL, EJB, XML, WSDL and their GUIs

� TIBCO requires Java or .NET, or maybe neither

22


Development Reuse� BEA requires AquaLogic Repository (Flashline) repository

� Oracle partners with HP/Systinet as a strategic partner for Service

Registry (SR) and bundles registry components with Fusion

� IBM requires WebSphere Repository, not UDDI 3, no support for

services built with other tools.

� TIBCO AM provides good integration to Repository

23


Deployment Skills� BEA has no deployment platform, requires enterprises to build or buy

(OpenView, Hyperic, Control Center), code required to deploy, less

configuration driven, properties files/pages versus EJB deployment

descriptors and deployment coding

� Oracle requires Enterprise Manager skills, proprietary scripting, APIs,

few available employees, few Google hits for help

� IBM requires Tivoli, proprietary platform, proprietary APIs, proprietary

scripting language

� TIBCO ActiveMatrix is the only platform we tested that provides

friendly GUI to orchestrate, deploy, and manage the services

24


Interoperability & Integration� BEA, IBM, and Oracle struggle with services and business flows build

outside of their own tools

� Consuming .NET services (message schemas, data types, transport

protocols)

� BEA offers clientgen utility to write Java proxies

� Oracle has Wizards in JDeveloper

� IBM has WebSphere Integration Developer and proprietary

Business Objects to work with .NET schemas

� TIBCO natively wraps .NET services into reusable components

25


Many Tools To Get Started� BEA WebLogic Server 10 used, but WLI, ALSB install 9.2

� BEA treats workflow as an external container

� IBM Requires 4 Products to build your first service

� Oracle Requires 5 Products to build your first service

� TIBCO ActiveMatrix enables Business Works components to

run on The Grid

26


TIBCO Areas for Improvement� TIBCO approach to SOA is different

� Java developers like to write Java code, ActiveMatrix does not

support EJB or Spring

� Do not make any assumptions about ActiveMatrix

• For instance, don’t assume that any of the competitor tools does orchestration.

• ActiveMatrix also requires WSDL->Service development.

• ActiveMatrix operates Java and .NET classes in a grid. My initial expectations was “service virtualization” would create orchestrations of externally running services.

27


TIBCO Areas for Improvement� ActiveMatrix has 3 designers

� ActiveMatrix interface is useful to define composites and has a

flow-like designer

� Actual business flow designer is BusinessWorks

� Mediation required another designer

� Policy management requires Policy Manager tool


28

Competitor Savings

TIBCO Savings
