  1. jan g. AppInf overview

  2. What's done • What's left to do (software) • What's left to do (hardware)

  3. Questions to bear in mind • does this meet our requirements? • can commercial software do any of this? • is there real value there at the moment?

  4. Model: farm of hosts • (diagram here)

  5. Use cases • We have a number of groups of users: • SRCT, developers, webmasters, etc. • Those users perform high-level operations • ...these expressed in terms of low-level operations • operations on a software+configuration stack • that's a relatively static model • no permanent state on hosts

  6. Deployment from a central configuration point • (diagram)

  7. Target applications • uPortal • difficulty: SSO • portal channels • difficulty: JNI for calendar • Other tomcat • blackboard, AFID, ISIS, etc. • Non-tomcat • OAS, PHP, ...

  8. Other potential applications • Non-webapp • mail spam filters? • ...?

  9. What's done • Low-level operations webapp: conf dir/ image/ image.war context.xml script/ parameterise-sso container-group front-end-host required-services

  10. What's done • Host configuration: conf dir/ callback-sockets deployment-data/ ssh keys ip mac-address os-image maint-user (deployment state: deployed software etc)

  11. What's to do: • Software • Scripts for physical network topology • (diagram in a minute) • Some more tidying-up • pretty ready for testing • Wrap up low-level operations into high-level scripts • (a few days)

  12. What's to do: longer term • Expand to push configurations to other software components • Nagios / other monitoring tools • Other container types • OAS • Related work • Performance, testing.

  13. What's to do: hardware • X4100s • waiting on power • physical configuration of network • PXE/dhcp a constraint (need non-10-subnet ?) • Apache->AJP • Host -> wide world • Host -> oracle • Host -> bobcat/other NAS

  14. Physical networking • (decisions needed: options outlined... diagram)
