There are several caching strategies that can be used in

distributed microservices:

▪ Cache Aside

▪ Read-Through

▪ Write-Through

▪ Write-Back, Write-Behind

▪ Cache Aside Strategy

Client checking the cache for data before making a request to

the backend service. When microservices needs to read data

from the database, it checks the cache first to determine

whether the data is available.

▪ If the data is available (a cache hit), the cached data is

returned. If the data isn’t available (a cache miss), the

database is queried for the data.

▪ The client will retrieve the data from the backend service and

store it in the cache for future requests.

▪ Data is lazy loaded into cache by client application.
