The document discusses selecting an enterprise service bus (ESB) and provides the following information: 1. It outlines an ESB evaluation framework that examines common and advanced ESB features. 2. It describes using the framework to understand how to implement common use cases and demonstrate ease of development with graphical tools and connectors. 3. It evaluates the composable architecture and enterprise fit by examining cross-component use cases, governance practices, security, and performance validation.

10. 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

15. Selecting an Enterprise Service Bus
Common Enterprise Integration Proof of Concept
1. Expose and consume services
1. Ease of deployment
2. Interoperable protocols
2. Connect to legacy back-end systems
1. Message transformation
2. Protocol mediation
3. Secure message traffic
1. Authenticate, authorize, and audit
2. Enforce security policies
4. Performance and scale to meet expected load and latency
requirements
1. Benchmark latency and throughput
2. Integrate into standard management consoles

16. Selecting an Enterprise Service Bus
SOA 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

17. Enterprise Deployment Use Case

18. ESB Comparison Categories
Performance
• 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 orchestration
Security and Identity Management
• Policy Enforcement Point (PEP) based on interoperable security model
(XACML)
• Integration with Identity providers
• Flexible OAuth authorization model

20. 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
