Quickstart Workshop

Quickstart Workshop

�Time & Place:

� 6 days in June 2011 in Bonn / Germany

�Team:

� 2 architects/developers from WSO2

� about 4 architects/developers from T-Systems

�Goal:

� Proof of concept for the required features

Quickstart Workshop

�Installation

� really simple – just unzip, change ports, and run!

� only 4s per ESB

� plus 30-60s to start up

Quickstart Workshop

�ESB Management Console

Pitfalls:

only one login cookieper host in a browser

… and we used ssh port forwarding to localhost

� maybe use several hostnames per host

SSL Certificates and hostname vs. DNS name vs. IP

symptom: empty soap request templates

� using hostnames worked for us

Quickstart Workshop

�SOAP Proxy

� straight forward

� may include WSDL

Pitfalls:

references to XSDs

� set schemaLocation in <xs:import>

reachable by the browser vs. reachable by the ESB

Quickstart Workshop<?xml version="1.0" encoding="UTF-8"?>

<proxy xmlns="http://ws.apache.org/ns/synapse" name="Soap2SoapProxy"transports="https http" startOnLoad="true" trace="disable">

<target><endpoint><address uri="http://1.2.3.4:8080/service/soap" format="soap11"/>

</endpoint><inSequence><log level="full"/>

</inSequence><outSequence><log level="full"><property name="out" value="out"/>

</log><send/>

</outSequence></target>

<publishWSDL>…

</publishWSDL></proxy>

</xml>

Quickstart Workshop

�HTTP GET Proxy

� simple

<rewriterule><action value="" regex="/services/MyProxy"

type="replace" fragment="path"/>

</rewriterule>

Quickstart Workshop

�Restful HTTP POST Proxy

� set ContentType, messageType, HTTP_METHOD

� trivial

Pitfall:

POST parameters got lost

� fixed by WSO2

Quickstart Workshop

�HTTP SOAP to GET Proxy

� extract variables via xpath

<enrich>

<source clone="true“

xpath="//query-string/text()"/>

<target type="property" property="POSTFIX"/>

</enrich>

� build URL

<property name="REST_URL_POSTFIX"

expression="fn:concat('service/insert?',get-property('POSTFIX') )"

scope="axis2"/>

Quickstart Workshop

�Custom Protocol (TCP) Proxy

� Implement and deploy two Java classes:

� custom MessageBuilder

� custom MessageFormatter

� requires axis2-wso2.jar

� quite easy

Quickstart Workshop

�Portability of ESB configuration

� in filesystem: simple copy

� in Governance Registry: export/import

� very nice and simple!

Pitfalls:

ESB must be running when the files are deployed,otherwise they are never read

Resources must be deployed first,otherwise proxy definitions may complain about missing files

Quickstart Workshop

�Filtering and Dynamic Routing

<filter xpath="fn:number(get-property('a')) > 10"><then><send />

</then><else><header name="To"expression="get-property('ENDPOINT')"/><send/>

</else></filter>

clean, but still verbose compared to non-xml languages“if ($a > 10) send(); else send(to => $endpoint)“

Quickstart Workshop

�Mapping based on DB table

<dblookup><connection><pool>

<password>wso2</password><user>wso2</user><url>jdbc:mysql://192.168.3.4:3306/wso2</url><driver>com.mysql.jdbc.Driver</driver>

</pool></connection><statement>

<sql>select mapped_id from mapping_table where id = ?</sql><parameter expression="get-property('ID')" type="VARCHAR"/><result name="mapped_id" column="mapped_id"/>

</statement></dblookup>

Quickstart Workshop

�Sequence Number Generation

� via database lookup

Quickstart Workshop

�Random Number Generation – Javascript

<inSequence><script language="js">var randomnumber = Math.floor(Math.random()*10);mc.setProperty("GeneratedID", randomnumber);</script><xslt key="IdMapper.xslt">

<property name="NEW_ID_VALUE"expression="get-property('GeneratedID')"/>

</xslt></inSequence>

Quickstart Workshop

�Traffic Shaping

� Throttling at Service Level

� Throttling at Mediator Level

� <throttle>-Sequence

� Policies

� Prioritization

� <priorityExecutor>

Quickstart Workshop

� Message Handling

� Buffering via JMS queue

� e. g. Apache qpid, ActiveMQ

� Resend

� Dead letter queue

Quickstart Workshop

� SSL

� the usual steps for handling certificates

� otherwise very simple

Quickstart Workshop

� WS-Security

� the usual steps for handling certificates

� and some stuff to declare the policy

� but otherwise quite simple

Quickstart Workshop

� OpenID

� ESB as an OpenID provider

�SAML

� ESB as a security token service

� quite some stuff to do

�SAML2 single sign on

Quickstart Workshop

� Business Activity Monitoring

� WSO2 BAM server

� ESBs cache and send events to BAM

� e. g. count by xpath expression

Quickstart Workshop

�Benchmarks

� with JVM memory settings increased

� up to 1680 req/s for SOAP proxy

� with client/ESB/backend running in VMson a single host with 2 x Xeon X7460

difficult to measure on VMs

� at least reasonable fast

Pitfalls:

the ESB may be faster than your client or backend

Quickstart Workshop

Result of the Quickstart Workshop:

� WSO2 Components really work fine

Final Result:

� Let‘s try and take WSO2

� all necessary features

� sufficiently mature

� relatively lightweight

� very good personal support

ESB Proxies

� Automatic ESB installation

� unzip, change ports etc.

� delivery built by Jenkins

� Automatic service installation

� One script to set up everything from scratch

ESB Proxies

�Task #1: Proxies for existing SOAP services

� 33 services, 159 XSDs

� modelled in Enterprise Architect

� WSDLs generated via EMF scripts (xtend/xpand)

ESB Proxies

Strategy:

� convert existing WSDL/XSDsto ESB proxy service definitions

� by XSLT called by ant

� customized by a host-specific config file with URLs

� deploy to the ESB via file copy

Pitfall:

Do not use subdirectories for XSDs!

ESB Proxies

�Task #2: Proxy for another SOAP service (task #2)

� simple

Pitfalls:

Every external real-world service seems to be a little different

namespaces, path conventions, casing,dependencies on external XSDs…

ESB Proxies

�Task #3: Proxy for non-XML HTTP POST and GET service

� use URL rewrite

� set body via <enrich>

Pitfalls:

Make sure to set no-proxy in your browser.

And make sure the browser cares.

Don‘t be fooled by your browser‘s cache.

� Use TcpMon!

ESB Proxies

�Task #4: Proxy with Transformation

� define XSLT mediators for in and out sequences

� generate ID via JavaScript

Pitfalls:

Enough. XSLT is designed for simple transformations,

not as a comfortable full-featured language.

Make sure your service is redeployed when necessary.

Changing just an XSLT may not be sufficient.

ESB Proxies

�Task #5: Proxy for binary XML

� one proxy for both XML and WB-XML

� use ApplicationXMLBuilder / -Formatter

Pitfalls:

It‘s simple as soon as you have found the right builder/formatterand the right options.

DISABLE_CHUNKING was required.

ESB Proxies

�Task #6: Proxy for POST with Query Parameters

� simple

Pitfalls:

Hit a bug - Query Parameters got dropped

� inSequence works fine if an URL rewrite is inserted

� Fix provided by WSO2

ESB Proxies

� Result:

� Everything works so far!

after fixing a bunch of simple problems

Next Steps

� NGTP (Next Generation Telematics Pattern)

� Binary messages

� Header may be processed by the ESB

� Plugin (Builder) to be implemented in Java

by NGTP Group, cc-by-sa, http://creativecommons.org/licenses/by-sa/3.0/legalcode

Next Steps

�Hardware Security Modules (Cryptoserver)

� Idea of HSMs:

� Offer restricted set of cryptographic operations

� But keep the keys inside

Next Steps

Why use Hardware Security Modules?

� Keys kept secure

� Hardware acceleration

� Non-standard implementations

Next Steps

�Using a Hardware Security Module

� Typically some binary TCP protocol

� Java module for the ESB may be developed

� With all operational requirements:

� Reconnect, failover, logging, …

Next Steps

�OSGi

� 2 ways to deploy services

� as a stand-alone web service e. g. on Tomcat

� as an OSGi module within the ESB or within Carbon

� Maybe go for OSGi

� Easier to handle?

� Better dependency management?

� With less resources?

� Better deployment options?

Next Steps

�WSO2 Stratos

� Software for Platform as a Service (PaaS)

� T-Systems plans to become a PaaS Providerfor the Connected Car Platform

Elektromobility Services based on the Connected Car Platform.

Existing services: Planned services:

� Mobility Services: choose best means of

transport

� Driver-specific informationen: e. g. heating

dependent on data from a server

� Charging: Authentifikation/Authorization,

Charge Control, Billing

� Track/Trace/Locate: where is my car,

when will I arrive?

� Diagnosis/Maintenance/Health:

Charge status, Status of eCar

components

� POI/Navigation: next Charging Point

Summary

�T-Systems provides the Connected Car Platform

� Generic platform for services used in cars

� WSO2 contributes the Middleware

� ESB

� Governance Registry, Identity Server, Stratos

�Development is ongoing
