Build a resilient solution

Many solutions depend heavily on functionality like search-based landing pages.

Service reliability

You should count on the reliability specified in your service level agreement (SLA). Nevertheless, as search is a central part of a solution, you should implement a graceful degradation strategy if the Search & Navigation service should become unavailable.

📘

Note

If Optimizely is not hosting Search & Navigation, Optimizely cannot guarantee the connection between an application and the Search & Navigation service.

Recommendations for coping with downtime

Leave the search-generated page sections blank

For example, a page displays a list of most watched products, which is fetched from Optimizely Search & Navigation. If Optimizely Search & Navigation is down, display a blank list.
