High Availability

There's no time for downtime

Maintain critical reliability for your web applications, APIs, and AI/ML services. Handle traffic spikes, DDoS attacks, network problems, and server errors with ease.

The Problem

Outages drive costs upward and trust downward.

Web applications, APIs, and AI-powered services are surging in popularity. High demand, cyber attacks, network design flaws, and deployment changes can negatively impact your services. 

Downtime saps revenue and erodes customer trust. High availability is key to keeping your users happy and helping infrastructure teams relax.

Outages are costly

On average, large enterprises can lose $400,000 per hour to surprise outages — regardless of sector.

Downtime is common

20% of organizations have suffered an outage in the past three years.

A major inconvenience

33% of reliability study respondents claimed that online disruptions were more frustrating than sitting in traffic or canceling plans due to bad weather.

"If we suffer outages, we look like a small company – like we’re not able to maintain things. It doesn't matter how good our product is, we're going to lose business. So reliable infrastructure is critically important. HAProxy’s stability has been absolutely fantastic. I have had zero problems with stability. It’s been absolutely rock solid."
