Most teams treat Lambda cold starts as a performance problem to be fixed. The more experienced position is to treat them as a design constraint to be managed, and to be precise about which functions actually need managing. According to…
Most AWS Auto Scaling configurations are set up once, inherited by the next team, and trusted indefinitely. The failure mode is never dramatic. It is the group that thrashes every three minutes and appears to self-correct. It is the Monday…
Riot Games cut $10 million from its annual infrastructure bill by moving from a self-managed Mesosphere environment to Amazon EKS with Karpenter. That figure makes headlines, and rightly so. What gets less attention is that a comparable savings opportunity is…
