Once you are up and running your primary job is to monitor that all your services are in good health. If something bad happens, network issue or crashes – you have to be notified on that as soon as possible. Hardering of the HTTP services and databases became a one of primary activities for any startup.
There few products on market that can do that, Pingdom and New Relic probably the most know. But they are paid and not that flexible as I want. So, I’ve created likeastore/heartbeat that for a month or so helps me to provide quality service.
