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)

• 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)
