===== Components =====

OSA is comprised of the following components:


  * Mongo (Host: sandy) → (Host: mongo01.osa)
  * Solr (Host: branch01) → (Host: pci01)
  * OSA-APIs (Host: branch01) → (Host: pci01)

The following components are used:


  * krawla (Host: sandy) (should be moved to a new machine: krawla01)
  * sim index (Host: tower01) (should be moved to something with lots of RAM and cores)
  * enrichment/feature extraction (Host: tower01) (maybe use the cloud?)
  * feed_import / krawla_export (Host: sandy) (should be moved to index04)


===== Planned Changes =====


  * sandy: 4 Cores
  * objectrec01: split into redis01 (4 cores, 16 GB) and mongo01.osa (4 cores, 48 GB)
  * merge mongo01.dev and mongo02.dev for a prelive mongo (currently on sandy)
  * move services on index04 to index03
  * product history no longer in meta_db, introduce a history collection
  * 2 session collections (1. krawla sessions, 2. osa session where only “good” krawla sessions are added by export)
  * NEW VM: krawla01 (4 cores, 16 GB)
