Detect Service Availability Issues Before Your Clients Do

January 17, 2012

When service capabilities get reused across applications and processes, high availability becomes imperative – key question: do you detect availability issues before your clients do? This is important for several reasons:

  • Unlike stand alone applications/processes, shared services impact several consumers. Not every consumer might be okay with your service being unavailable for an extended period of time. The same service might be in the critical path for some and not so much for others
  • For some service capabilities, running them in a partial mode might be acceptable – e.g.  operating out of a cached copy of data rather than fetching it from a live database, or servicing only read only operations during an unexpected outage, etc.
  • Some consumers might have regulatory processes that are dependent on services being available – a service being unavailable might cause SLA breaches

Finally, consumer trust is key for systematic reuse – if they perceive service availability as a limiting factor, it will be harder to convince them to use services – including current and upcoming integrations
