How to use OpenTelemetry and Grafana Alloy to convert delta to cumulative at scale

Migrating to a Prometheus-based ecosystem with Grafana Alloy, which integrates OpenTelemetry, makes handling metrics easier, especially when converting delta metrics to cumulative ones. This post details the algorithm used for this conversion and outlines the load balancing and container setup necessary for scalable deployment. It also mentions recent updates to the OpenTelemetry Collector, making the process more efficient and scalable.
