Introduction to AdroitLogic and UltraESB
0 likes468 views
This document summarizes the history and capabilities of AdroitLogic's UltraESB product. It describes how UltraESB was created based on lessons learned from previous ESB implementations. Key features include high performance through non-blocking transports and zero-copy messaging, simplicity through a lightweight architecture based on Spring, and a focus on quality through extensive testing and benchmarking. UltraESB can be used for application integration, API management, and B2B integration through solutions like the AS2 Gateway.
Introduction to AdroitLogic and UltraESB
- 1. “Better By Design” Integrating and connecting systems, trading partners and users together
- 2. ● Founded in January '10 ● Open Sourced UltraESB in August '10 ● AS2 & File Exchange Gateways released '12 ● API Director released '15 ● Focused on ESB++ ● Enhanced by real customer needs About AdroitLogic
- 3. HISTORY ● Why another ESB? beta user of Aqualogic Service Bus in 2005 Performance: Zeus XTM vs BEA Aqualogic ● Joined WSO2 in April 2006 First ESB with non-blocking http/s transports Public ESB performance benchmarking begins ● Asankha (Founder) + Ruwan (Director of Engineering) wrote over 80% of the Apache Synapse ESB
- 5. Synapse / WSO2 ESB ● Axis2 was a SOAP “client” and “service” framework ● Many ugly hacks were required to use it for an ESB ● Disadvantages outweighed any benefits ● All messages were “SOAP”ified – even Files! ● Became very difficult to unit test ● Complex to configure for end-users ● Development of Graphical “front-ends” didn't help ● Difficulty to use external code / customizations ● OSGi was the last straw!
- 6. ...Objective! build the fastest ESB make it Simple to use and extend emphasis on Quality
- 7. Significant Milestones ● Ruwan Linton joined AdroitLogic in 2011 ● Jesta Digital migrates to UltraESB ● AS2 Gateway and AS2 support introduction ● Selection by Walmart for eCommerce ● Release of the API Director
- 8. Users of our technology
- 9. ESB within an Organization
- 10. ESB as a Gateway HTTP/S AS2 S/FTP Email
- 11. API Management ● Exposing internal services ● For access by external partners ● Usually REST based ● SOAP/POX etc also possible
- 12. Common Concerns ● Could this request be an attack? ● Is a client identified, authenticated & authorized? ● Is the request exceeding the allowed rate limit ● Is the quota (long term) being exceeded ● Is the request acceptable? ● Should any routing be performed ● Who is calling, what services – logging, auditing etc ● Whats the overall health, performance/metrics
- 13. Key Functions ● On boarding Services and Consumers ● Credential Management ● Mediation, Logging, Auditing ● Rate limiting, Metering & Billing ● Performance and SLA ● Management / Analytics / Alerts ● Administration / Developer Portals & Tools
- 14. ● Security ● Client ID, Basic/Digest/OAuth, WS-Sec.. ● AuthN – Headers, IP address, LDAP.. ● Protection - SSL, message encryption ● Validation – Schema based, XSS scanning.. ● Deliberate attacks – Slow clients ● Mediation ● Routing, transformations, caching, etc
- 15. ● Policies ● URL/Header/Payload sizes, HTTP methods ● Response time ● Throttling / Rate limiting ● Quota (more long term) ● Attack detection (Content Type, Payload etc) ● Developer Portal / Tools ● Registry, Documentation, Sample usage ● Test endpoints, utilities, service meta data ● Consumer and Service On-boarding ● Metrics, Alerts and Reporting
- 16. UltraESB as an ESB ● One of the youngest, since Jan 2010 ● Based on a lot of previous experience and knowledge with ESBs ● But a completely clean & new implementation ● Knew what worked, what didn't and what should be done better ● Technical innovations ● Focus on performance and quality from the start ● Java or JSR 223 scripts dynamically compiled for mediation ● Simplicity ● Based on Spring framework and a few very stable libraries ● Ease of management / monitoring based on ZooKeeper & JMX
- 17. Solutions based on the ESB ● AS2 Gateway ● Utilizes AS2 based B2B trading support of the UltraESB ● AS2 trading station as a service – http://as2gateway.org – Supports Invoicing – Based on requirements from two leading retailers in Europe ● On-Premise deployments for enterprise customers ● API Director ● API Management solution ● Integrated ESB service management capabilities
- 19. AS2 Gateway
- 21. API Director
- 23. Proxy Services
- 24. Transports & Message formats ● Non-Blocking HTTP/S with Zero-Copy ● JMS, AMQP, Email, File, S/FTP/FTPS/Samba, Timer (Quartz), TCP/S, MLLP/S ● Protocols ● REST, SOAP, Hessian, Protocol Buffers, Fast Infoset, AS2, Binary/Custom TCP etc ● Payloads ● XML, JSON, Text, Binary, CSV, Fixed Width, EDI
- 25. Sequences, Interceptors & Mediation msg mediation logger Fragment, Class, Spring bean.. Native byte code execution Use try-catch-finally Javadoc for API
- 26. Endpoints
- 27. Achieving “Performance” Zero-Copy Proxying + Non-Blocking IO RAM disk / VTD XML end-to-end principle
- 29. Core Architecture ● RAM disk based file cache ● Speed of RAM with ease of Files ● Better utilization of memory with smaller heap and low GC overhead ● Use of Zero-Copy / sendfile with DMA ● JMX for management of nodes/clusters ● Separate Coordination & Control from State replication ● No SPF, support HA and FO of services on nodes ● No canonical payload format ● Allow dynamic, yet atomic updates
- 31. Continuous Benchmarking ● Since 2005, comparing against ● Mule, BEA, ServiceMix, WSO2, Talend, Jboss, Petals and Fuse ● ESB Performance Benchmark ● http://esbperformance.org ● All resources, scripts and instructions openly published ● Ready-to-run EC2 image used for results shared ● Direct proxy, CBR (Transport/Message Header & Content), Transformation, WS- Security ● Community based improvements to the tests and resources – From Talend, Mule and ServiceMix/Camel – All found issues with their ESBs by using the benchmark and fixed them – Independently validated the results seen
- 32. Last Round 6
- 33. Focus on Quality & Ease of Use ● Close to 50% code coverage ● Public API as separate Maven artifact shields customers' custom code binding into ESB internals ● Start / Debug / Profile / Unit test / Load test – all within the IDE ● Many things based on few stable libraries such as Spring ● No OSGi or classloader complexities – simple to extend
