Problem #1: Persistence configuration
Problems arise as the application’s load grows, resulting in a significantly larger database load.
To avoid such problems, you must thoroughly understand the persistence technology in use and appropriately configure all configuration settings so that its functionality is aligned with your business domain’s requirements.
Problem #2: No Caching
When no caching is utilized, problems arise because it must be fetched from the database each time a resource is needed. When caching is employed, issues arise as a result of improper configuration.
It is important to note the fixed size of a cache and the distributed cache setup. Unlike pools, which provide stateless objects, cached objects are stateful. As a result, a cache must be appropriately set to avoid memory exhaustion.
Problem #3: Distributed caching
When many caches are set to many servers, synchronization is required. As a result, a cache update is propagated to all servers’ caches. When caching is implemented effectively, an increase in application load does not increase database load.
