This is a sizing tool for COS Lite deployments. It used to live here but got lost in one of my many blog migrations.

Use the sliders above to interactively adjust your log and metric ingestion rates and retention period, and get an estimate of the CPU, memory, and disk sizing you may need for your COS Lite deployment.

The last couple of years, there has been quite a lot of development in the area of lowering the barrier of entry for observability. There are now quite a few, reasonably mature options out there that lets you set up a good monitoring stack either through a few clicks or by a few one-liners in the terminal.

In the managed open-source space, the most successful one so far probably is Grafana Cloud, but there definitely is no shortage of closed-source vendors providing APM solutions where everything you need to get started is to drop either a single or multiple agents into your cluster or your machine.
