Messaging Services and Client Software Lionel Cons Massimo Paladin EGI Technical Forum - Prague, 18 th September2012 EMI is partially funded by the European Commission under Grant Agreement RI-261611 Outline Recommendations for messaging

  1. Messaging Services and Client Software Lionel Cons – Massimo Paladin EGI Technical Forum - Prague, 18 th September2012 EMI is partially funded by the European Commission under Grant Agreement RI-261611

  2. Outline • Recommendations for messaging services • From use cases to client software • Recommended libraries and software EMI INFSO-RI-261611 14/09/2012 CERN 2

  3. Dedicated messaging services of independent brokers • Dedicated services – Application isolation – Application specific broker tuning – Compatible applications can be grouped • Independent brokers – Horizontal scalability – Easier management and operations – Heterogeneous products (when needed) – Goes well with load-balanced DNS EMI INFSO-RI-261611 14/09/2012 CERN 3

  4. Dedicated messaging services of independent brokers EMI INFSO-RI-261611 produce to any consume from all 14/09/2012 CERN 4

  5. WLCG messaging services EMI INFSO-RI-261611 14/09/2012 CERN 5

  6. Messaging software • Many messaging brokers available – Recommendations available in our wiki • Many protocol level client libraries available – Different protocols STOMP AMQP OpenWire … – Several alternatives C / C++ X X X … Java X X X … per language Perl X X … Python X X … Ruby X X … EMI INFSO-RI-261611 … … … … … 14/09/2012 CERN 6

  7. Developing messaging clients • Easy to get something working • Using different protocols and programming languages leads to code duplication • Error handling is not trivial at all (messaging is mostly asynchronous) EMI INFSO-RI-261611 • Hard to get something working reliably 14/09/2012 CERN 7

  8. How to solve this? • What about LEGO bricks? – Small reusable components – Flexible when combined • What are our bricks? • Message Queue • Messaging Transfer Agent – File based message queue – Transfer messages between a EMI INFSO-RI-261611 broker and a message queue – Simple and robust API (all combinations) 14/09/2012 CERN 8

  9. Simplifying the producer EMI INFSO-RI-261611 14/09/2012 CERN 9

  10. Simplifying the consumer EMI INFSO-RI-261611 14/09/2012 CERN 10

  11. Scaling the consumer side EMI INFSO-RI-261611 14/09/2012 CERN 11

  12. In practice 1/2 Producers and consumers only need to interact with the Message Queue – Perl: perl-Messaging-Message + perl-Directory-Queue – Python: python-messaging + python-dirq – simple algorithm, easy to port to other languages EMI INFSO-RI-261611 14/09/2012 CERN 12

  13. In practice 2/2 Messaging Transfer Agents – STOMP protocol: stompclt (production ready) – AMQP protocol: amqpclt (being tested) stompclt sender example: stompclt receiver example: EMI INFSO-RI-261611 14/09/2012 CERN 13

  14. How can we handle an elastic service? EMI INFSO-RI-261611 14/09/2012 CERN 14

  15. Reliable services through supervision • Proven concept (Erlang/OTP) – Workers do their work – Supervisors monitor workers – All are defined in a supervision tree • Flexible implementation available ( simplevisor ) – Non intrusive – Handle service evolution EMI INFSO-RI-261611 14/09/2012 CERN 15

  16. More about software • The EMI Messaging Product Team – Identified the reusable components – Improved the existing ones – Developed the missing ones • All the components are available – Most are production ready – The others are being finalized – All are available in EPEL EMI INFSO-RI-261611 14/09/2012 CERN 16
