Selecting an Enterprise Service Bus Monitoring Requirements and Analysis Production Enterprise Use Cases Middleware Adoption Process Evaluation Development Framework Vendor Proof of Concept Comparison

Selecting an Enterprise Service BusService Oriented Architecture Focus Areas1. Interoperability2. Resource location virtualization3. Separation of concern4. Abstraction5. Loose coupling6. Declarative policies and platform independent models

ESB Evaluation FrameworkEvaluation Framework Features• Common features • Routing • Protocol bridging • Message transformation • Service agent hosting• Advanced features • Resource adapters • Composition • Orchestration • Reliable message delivery • Event processing • Transactional integrity • Message Exchange Pattern (MEP) mediation • Dynamic location and binding, load balancing • Message validation • Capability mediation • Security mediation (federation) • Tooling

ESB Evaluation Framework Mind Maphttp://wso2.org/library/webinars/2012/08/wso2-advantage-webinar-esb-evaluation-framework

Selecting an Enterprise Service Bus Use Cases• Understand process to implement common use cases • Endpoint connectivity • Message validation • Message transformation • Content routing • Exception handling • Security• Demonstrate Ease of Development • Provides Graphical ESB Development Workbench • Cloud Integration platform offering (iPaaS) • Cloud connectors and legacy adapters• Evaluate composable architecture and enterprise fit • Cross-component use cases • Facilitates SOA Governance practices • Security and Identity Management• Validate performance

Understand Process to Implement Common Use Cases

Understand process to implement common Use Cases WSO2 Mediators • Sequence: invoke a named set of sequences • Send /Event : send a message or event • Callout: external blocking service invocation • Filter: Filter a message with a given Xpath • In/Out: predefined filter sequence • Switch: conditionally execute mediators based on regex match • XSLT / Smooks/ Xquery: message transformation • Enrich: run specific actions • DBLookup: augment message contents • Route: content routing • Clone / Iterate / Aggregate: message copy, splitting, and aggregation • Cache: reduce back-end request load • Validate: validate message content • Rewrite: re-write URL • Header: set header values • Throttle: limit endpoint usage • Log: Log a message • DBReport: write to database • Fault: post exception • Drop: stop processing • Enqueue / transaction: message queuing and transactions • Entitlement: apply XACML policy • OAuth: support OAuth authorization

Selecting an Enterprise Service BusCommon Enterprise Integration Proof of Concept1. Expose and consume services 1. Ease of deployment 2. Interoperable protocols2. Connect to legacy back-end systems 1. Message transformation 2. Protocol mediation3. Secure message traffic 1. Authenticate, authorize, and audit 2. Enforce security policies4. Performance and scale to meet expected load and latency requirements 1. Benchmark latency and throughput 2. Integrate into standard management consoles

Selecting an Enterprise Service BusSOA Governance use cases• Service Lifecycle management • Create, deploy, version, deprecate, retire• Service versioning • Approval process • Versioning scheme and tracking• Promotion • Checklists • Environment deployment• Run-time management • Enforce security policies • Comply with Service Level Agreements

Enterprise Deployment Use Case

ESB Comparison CategoriesPerformance• Load Balancing and Failover built-in • Pluggable models can include affinity based LB• Full REST Support (XML and JSON) • Especially used in Mobile environments • Can bridge into SOAP or other enterprise systems• Message Relay Mode and Relay Transport • Excellent performance for 100% streaming• Priority Execution, Cache and Throttling • Manage workloads within the ESB as well as throttle backend • Cache content locally if appropriate• Service Chaining • Asynchronous lightweight orchestrationSecurity and Identity Management• Policy Enforcement Point (PEP) based on interoperable security model (XACML)• Integration with Identity providers• Flexible OAuth authorization model

Choose the right architecture component• ESB • Shared services • Centralized mediation, logging, and routing• Integration framework • Traditionally a library facilitating endpoint connectivity embedded within application • Re-cast as lightweight proxy (similar to WSO2 Elastic Load Balancer, WSO2 Cloud Services Gateway, and WSO2 API Gateway)• Message Broker • Message store and forward component with reliable, guaranteed delivery• Data Services • Transform data into RESTful entity services• API Gateway • Efficient consumer on-boarding • Security and QoS management at the edge • Endpoint promotion, discovery, and documentation• Governance Registry • Manage service lifecycle • Enable late-binding on endpoint location and policy definitions
