What is HAProxy

What Is HAProxy?

HAProxy is a popular, open-source software load balancer. You’d put it in front of web servers or any other services that work over HTTP or TCP, so they can be reached in a round robin or a least-used fashion. HAProxy has other features useful in this context, such as rate limiting or handling authentication.

Since HAProxy is often the gateway to important services, you’ll want to know it’s healthy and performing well. With its wide collection of HAProxy metrics, Sematext Monitoring makes this easy and efficient.

        We looked into running our own Elastic Stack, and quickly realized that was a job and specialty within itself. We are a small startup and every dollar counts. Wasting precious and expensive sysadmin time on managing things far out of our project scope really isn’t an option
