▪ Fallback Pattern provides an alternative behavior or response

if a request fails or times out.

▪ If a service is unavailable, the client could use a cached

version of the data or display a default message to the user.

▪ It is used to provide an alternative course of action when a

service call fails or takes too long to complete.

▪ Define a fallback function that is called if the service call fails

or times out, and the function provides an alternative

response.

▪ In microservices, the fallback pattern help to improve the

overall reliability and stability of the system.

▪ If the payment processing service is unavailable or takes too

long to complete a request, the fallback pattern could be used

to provide an alternative response.

▪ I.e. displaying an error message or offering the user the option

to try again later.
