Agendao Modern enterprise and ESBo WSO2 ESB featureso What is new in WSO2 ESB 4.9.0?

- Inbound Endpoints - Coordination support for scheduled tasks - MSMP improvements - Extended support for MQ protocols (Kafka, MQTT, RabbitMQ)o Connector storeo Performance and Stability

Modern Enterprise and ESBo Modern Enterprises - Comprised of so many heterogenous systems

and services- built based on open standards, custom-built,

acquired from a third party, part of a legacy system or any such combinationo Integration- Organizations move away from monolithic systems- Multiple Systems connected via SOA as the blueprint

Modern enterprise and ESBo Spaghetti integration

WSO2 ESB overview

o A lightweight, high performance ESBo Comprehensive REST, SOAP, WS-* support o 100+ Connectors (Salesforce, Paypal, Twilio and many more) o SAP, FIX, HL7 - Domain specific solutionso Zero Code/Configuration driven o Extensible and Scalable

New features (Inbound Endpoints)

o Creating inbound messaging channels dynamically. o Listening Inbound – HTTP, HL7, TCP, WS-RMo Polling Inbound – JMS, File/VFS

o Injects messages directly from transport layer to mediation layer without going through the axis engine

o Supports multi-tenancyo Dedicated thread pools per inboundo Built-in cluster coordinationo Extending the functionality with custom inbound endpoints

Listening Inbound Endpoints

o Starts message listening interfaces dynamically o Eg: HTTP Inbound – Dynamically create HTTP inbound message interfaces on a specified port

and inject the messages into ESB message flow o Fully supported in multi-tenant environments.o HTTP, HL7, WS-RM, TCP Inbound Endpoints o Message filtering capabilities with HTTP inbound

Polling Inbound Endpoint

o Dynamically creates message polling interfaces. o Eg: JMS Inbound Endpoint – polls a given JMS queue and inject messages into an ESB

message flow. o Fully supported in multi-tenant environments o Coordination support o JMS, VFS/File Inbound Endpoints

Polling Inbound Endpoint - Coordinations

o One consumer per cluster vs multiple consumers

Single Consumer Multiple Consumers

New Feature (Scheduled Tasks - Coordinations)o Executing tasks in a clustered or multi-tenant environments.o With the cluster coordination support, tasks will always run on an available

node in contrast to the pinned server concept which was used with earlier versions

o Two modes of operation- Run in a single node (one task per iteration)- Run in multiple nodes (n tasks per iteration)

Scheduled Tasks - Coordinations

o Executing tasks in a clustered or multi-tenant environments.o Leader election/failover support

Enterprise Messaging

o Kafka, MQTT and RabbitMQ support

Enterprise Messaging (Kafka support)

o Apache Kafka is publish-subscribe messaging rethought as a distributed commit log.

o Fast, Scalable, Durable and Distributed by designo Kafka inbound endpoint to connect to inbound connectionso Kafka connector for outbound communicationo Two modes of operation

- High level- Low level

Enterprise Messaging (MQTT support)

o Lightweight broker-based publish/subscribe messaging protocol o Designed to be open, simple, lightweight and easy to implement. o Ideal for use in constrained environments like mobile devices and IOT.o Improved MQTT transport(axis2 transport) listener-sender implementation.o MQTT inbound endpoint for more versatile integrations

Enterprise Messaging (RabbitMQ support)

o Robust, easy to use, well supported messaging solutiono Improved the stability of the rabbitmq transport (axis2 transport)o Automatic connection recovery for RabbitMQ transport in case of failureo All content-types are now supported by RabbitMQ transporto Introduced the new feature rich inbound endpoint for rabbitmq o Added the SSL support for rabbitmq inbound/transport

Message Store Capability Improvements

o JDBC Message Store.o Easy to connect.o Quick transactions.o Ability to work with a high capacity for long period of time.

o RabbitMQ Message Store.o Robust messaging for applications.o Easy to use

Message Processor - Coordinations

o Fully supported in multitenant environmentso One consumer per cluster – Guaranteed in-order deliveryo Multiple consumers – Guaranteed delivery

Single Consumer Multiple Consumers

Failover Message Store Message Processor

o Failover Store.o This allows the message store to store messages in the failover message store if the original

message store is not available.o Scheduled Failover Message Processor.

o Move messages which were forwarded to the failover message store to the original message store when it becomes available again.

140 + Connectors

o A connector is a ready made and convenient tool to reach web API’s.o ESB Connector Store(www.store.wso2.com) : 140+ connectors.

Performance and Stability

o Fastest open source ESB.o Battle tested for most extreme

conditions across numerous deployments.

o Proven case studies – handling billions of transactions.

o Performance improvement over the ESB 4.8.1
