Shadow It

Offsite Backups in the cloud

Part of any good backup strategy is to ensure a copy of your backup is stored in a secondary location, so that if there is a major outage (datacenter failure, office burns down, whatever) there is a copy of your data stored elsewhere. After all, what use is a backup if it gets destroyed at the same time as the original? A large enterprise may do cross-datacenter backups, or stream them to a “bunker”; smaller business may physically transfer media to a storage location (in my first job mumble years ago, the finance director would take the weekly full-backup tapes to her house so we had at most 1 week of data loss).

Managing the cloud management layer

A typical cloud engagement has a dual responsibility model. There’s stuff that can be considered “below the line” and is the responsibility of the cloud service provider (CSP) and there’s stuff above the line, which is the responsibility of the customer. Amazon have a good example for their IaaS: Where the line lives will depend on the type of engagement; the higher up the abstraction tree (IaaS->PaaS->SaaS) the more the CSP has responsibility.

Shadow IT

Shadow IT isn’t a new thing. Any large corporation has seen it. Sometimes called “server under desk” or “production desktop”. Sometimes it grows out of a personal project that started on a spare machine and that gradually morphed into a mission critical machine… but without any of the controls and tools normally associated with production infrastructure (patches, backups, DR, access admin, security scanning…). Other times it grows out of a desire to do things quickly; all of those controls and tools take time and can hinder the developer experience.
