Current and proposed deployment of Openlibrary hardware. Basic theory: |

1) Pharosdb and pharosdb-bu are IA Black boxes, powerful but one-off machines that are unsupported by IA Operations. We should stop running production services on them but can keep using them for development, crawling, etc. |
|
|
3 |
|
|
|

2) We are sometimes running development tasks on production servers. This should stop, both for load and reliability reasons. It was probably a dev task that took down Wiki-beta a couple weekends back and caused some inconvenient downtime. |

3) We should package the OL server and a mini-database for easy installation (maybe as an LVM container) on a desktop workstation. That will let us do a lot of development locally instead of tying up cluster nodes running dev services. So the table below lets go of a couple of dev machines. In practice we may be able to run some dev tasks on the production backup servers but we shouldn't run such tasks on production primaries. |
