High-load ≠ high-cost: how to optimize infrastructure without losing reliability [ukr]

In high-load systems, infrastructure costs often grow not because of the load itself, but because of inefficient architectural decisions: overprovisioning, excessive use of managed services, unnecessary data movement, incorrect SLA decisions, and the lack of a transparent cost model.

At the conference, we will discuss how to approach cost optimization as a full-fledged architectural practice, rather than a one-time resource reduction exercise. We will also cover workload profile analysis, identifying real bottlenecks, building unit economics for infrastructure, traffic optimization, caching, CDN, observability, and controlled service degradation.

Separately, we will look at the trade-off between performance, reliability, and cost: where maximum fault tolerance is truly required, where an eventually consistent approach is sufficient, and where managed solutions should be replaced with a simpler self-hosted architecture.
