Fault-tolerant availability has been built into our design since the very beginning.

Get closer to 99.999% uptime with the HAProxy suite of products.

Key Principles

High Availability is the principle of keeping a website’s content accessible throughout the year. An uptime as close to 100% as possible is today’s chief aim for any company striving to perfect their web operations.

To achieve high availability at each layer of your infrastructure, from the network edge down to the application level, our products tackle the complexity for you.

With a suite of in-built features contributing to this goal as well as a centralized hub for managing fleets of load balancers, HAProxy Technologies load balancing solutions bring absolute availability closer than ever.

HIGH AVAILABILTY PLAYBOOK

The Fight to Remain Available

Maintaining this high uptime means fending off several key threats. Faced with the challenge of staying online, companies should be on the lookout for the following common weaknesses.

High Availability Network Design Flaws
SOLUTIONS:

  • Failover
  • Advanced Health Checks
  • Retry Requests
  • Circuit Braking
  • Support Tools

Network Design Flaws

SOLUTIONS:
Failover, Advanced Health Checks, Retry Requests, Circuit Braking, Support Tools.

Network Design Flaws

A well-designed system is the first line of defense against downtime. Minimizing failure-points by running a website across several servers is key, with a seamless backup plan for outages like HAProxy Enterprise’s automatic failover settings when one goes down.

But keeping a network healthy is always preferable to a server taking a sick day. In order to ward off these interruptions before they strike, benefit from the advanced health checks offered by the HAProxy suite of products to continually monitor your servers for downtime and errors. And when components do fall under-the-weather, support for retry requests on other servers as well as circuit breaking means that traffic can be routed around unhealthy server groups during longer outages.

The same principles apply for the load balancers themselves. By creating a cluster of load balancing instances you enable redundancy in case one fails, and with support tools for an Active/Active or Active/Passive setup, your backup load balancing instances will always be ready. And with the HAProxy Fusion Control Plane you can fluidly manage the setup and configuration of these multiple load balancers all in one place.

High Availability Security Attacks
SOLUTIONS:

  • Web Application Firewall (WAF)
  • PacketShield

Security Attacks

SOLUTIONS:
Web Application Firewall (WAF), PacketShield

Security Attacks

The internet can be a dangerous place. Given load balancers are often the first line of defense against unwanted visitors, taking advantage of a sophisticated security system like the HAProxy Enterprise Web Application Firewall to scan requests for malicious payloads as they arrive will allow you to stop threats before they can reach your servers and disrupt your uptime.

Defending against denial-of-service threats can necessitate a different response. A network layer solution like HAProxy ALOHA’s PacketShield is another approach, and ideal for stateful packet filtering of illegitimate traffic.

High Availability Deployment Risks

  • Slow Start / Slow Stop
  • Hitless Reloads

Deployment Risks

SOLUTIONS:
Slow Start / Slow Stop, Hitless Reloads

Deployment Risks

Continuous delivery can mean that application deployments happen frequently, even several times per hour, meaning that updates must be carefully planned so visitors can continue to be routed through as services reboot.

Taking advantage of HAProxy Enterprise’s slow start and stop will steadily increase and drain traffic to servers as they undergo this process. Hitless reloads also allows seamless updates on the Load Balancer itself – meaning that it can continue to route traffic as configurations are updated.
