In the previous section, I discussed using a cache for the purpose of preserving application state between parallel deployments of the same application. This is one of the most common use cases for caching in modern cloud-based architectures. However, useful as it may be, this sort of distributed session cache can introduce a whole host of challenges to the application design.
Distributed caching systems
A cache-friendly architecture
Caches have historically been used to improve performance by reducing latency or operation times. With a session cache for distributed architecture, however, the cache itself is not intended to provide any specific performance improvement on a given operation. Instead, it's designed to facilitate...
