'So, what is it you exactly do?' - Part four, monitoring

Here's a scenario...

At 4:30AM every Thursday (sysadmin's time), a server's site suddenly spikes in load, because a full backup takes place at such a time, which is not an off-peak time in terms of traffic due to international visitors.

A bunch of users visiting a site on that server receive a flurry of 502 errors trying to load some content - a form of application timeout due to the taxing effect on the CPU related to the backup process.

One-touch provisioning and auto-monitoring of new servers

I've recently been doing some very innovative work for the very clever gents at Code Enigma, where I've been working on some interesting projects:

1. an automated 'zero-touch' dev/stage/live deployment system for their enterprise Drupal applications (developers no longer need to ssh in to servers to do deployments)

2. automatic 'one-touch' provisioning and configuration of new hosting cloud services.

(More on the dev/stage/live zero-touch deployment soon :) )
