Cache Warming Strategies PHP 5.0+
Pre-populating a cache before traffic arrives — preventing the cold-start thundering herd where every request misses a cold cache simultaneously after a deploy.

Cloud Cost Optimisation
Systematically reducing cloud spend without reducing capability — right-sizing instances, using reserved/spot pricing, eliminating waste, and architecting for cost from the start.
