> 1000 jar files in production
Combined to 400 different GUIs and 200 server programs
Up to 1000 processes running on 550 machines
Developed by 80 people from 10 different groups
Front-End Layer (C/C++)
550 different device types
70’000 device instances on 1000 different front-end machines
Developed by 80 people from 8 different groups

8. Middleware Mandate & Scope
Standard set of MW solutions
Centrally managed services
Track & optimize runtime parameters
Well defined feedback channel for users
Provide support & follow-up issues
Scope: CERN Accelerator Complex
Operational 24*7*365
Must be Reliable & High Quality
In all Eqp. groups (3 dpts: BE, EN, TE)

Activities
Worth highlighting new NEW areas:
-Rollout of the new tracing facility, closely linked with ACET
-Contribution to the SIP4c++
-Kickout of CommonMakefile
ACET = Accelerator Controls Exploitation Tools
CommonMakefile = Standartizing C++ Project Layout, Build, Testing and I

13. Middleware Infrastructure in numbers
4’000 CMW Servers
85’000 Devices => 2’000’000 Properties
24 Proxies (10 Injectors, 14 LHC)
20 JMS Brokers (10 single Brokers, 5 HA Clusters)
15 DIP Gateways
2 RBAC A1 Servers
2 Directory Servers
1 Configuration Server
1 Log Converter & DB Writer
JMS:
Print as money :
~3200 times the LHC
Next : No of brokers.
CMW Proxies :
gained popularity as they run stable
