When planning your database HA architecture, the size of your company is a great place to start to assess your needs. This base architecture keeps the database available for your applications in case the primary node goes down, whether that involves automatic failover in case of a disaster or planned switchover during a maintenance window.

When designing an architecture, many components need to be considered before deciding on the best solution. In this context, features like filtering, firewalling, or caching are redundant and may consume resources that could be allocated to scaling.

For most high-end processors these values have remained in the range of 75% to 85% of the peak DRAM bandwidth of the system over the past 15-20 years — an amazing accomplishment given the increase in core count (with its associated cache coherence issues), number of DRAM channels, and ever-increasing pipelining of the DRAMs themselves.

Stable media is commonly physical disk storage, but other devices and certain caching facilities qualify as well. Many high-end disk subsystems provide high-speed cache facilities to reduce the latency of read and write operations. This cache is often supported by a battery-powered backup facility.

On your first try, you can use it as a benchmark for optimizations later. Active Memory Caching. When you want to get data that you already had quickly, you need to do caching — caching stores data that a user recently retrieved. Caching partially stores your data and is not used as permanent storage.
