2.2.5 Applying the technique(s)
Apply application environment scaling, tuning, and adjustments to a test environment first.
Evaluate performance and scalability impact to a component ad well as determine how each change affects the surrounding components and the end-to-end infrastructure. A situation where improvements on one component result in an increased (and unnoticed) load on another component is undesirable.
In many cases, all techniques cannot be applied because one or more of the following statements are true:
- Investing in the techniques, even if it would prove helpful, is not affordable.
- There is no perceived need to scale as much as the techniques will allow.
- Cost/benefit analysis shows that the technique will not result in a reasonable payback.
Therefore, there must be a process for applying these techniques in different situations so that the best return is achieved. This mapping is a starting point and shows the components to focus on first, based on application workload.
