Microsoft

For building scalable and highly available applications, Azure Application Gateway does most of the job on behalf of you; automatically load-balancing traffic from a number of users to a number of back-end servers. This ensure scalability and availability. The in-built security is great as can be expected from Microsoft, and user has a variety of tools for monitoring the health of the load-balancing function as well as the health of back end servers behind it.

Open Source

It prevents a single server failure from being a downtime event by adding redundancy to every layer of your architecture. A load balancer facilitates redundancy for the backend layer (web/app servers), but for a true high availability setup, you need to have redundant load balancers as well. So it is well suited for all production related servers and less suited for individual servers that do not require redundancy.

Pros

Microsoft

  • Easy integration with Load Balancer and Azure Scale Set to provide a full solution for traffic management.
  • With rich routing rule, we could use one Application Gateway as the central point for all internal applications to expose to the external network.

Open Source

  • A few, rare times each year, HAProxy CPU utilization spikes to 100% and server has to be rebooted - this may be related to HAProxy OR it could be an external factor causing this.

      It is very easy to use. I was able to find a lot of documents for it on the internet. Very good community support. There are lots of examples available to try. We mostly use a command-line user interface to interact with it. The CLI is also super easy to use and very easy to interact with

      I don’t like that it's part of the Microsoft brand. In general, I am not a fan of Microsoft products but Azure gets it right.

      We haven't used customer support. We mostly used the community version. We build a multi-node HAProxy cluster with HA to the proxy itself using opensource plugins available. With the support available on the internet and the documents available we don't need to use much customer support.

      Alternatives Considered

      Microsoft

      NGINX and Kong are open sources and we don't like open-source. We want an enterprise application that helps us in the production workload.

      We chose HA Proxy because it is cheaper than a hardware balancer, it is an open-source solution with a large community behind it and with constant updates. It also allows custom scripts according to needs.HA Proxy is a solution used in many internet sites like GitHub, Reddit, Twitter, and Tuenti.

      Return on Investment

      Microsoft

      • Costs increased for the company, so expenses were more than before.
      • Was able to get better user experience so users won't feel the website is useless.

      • Significantly lower investment vs competitors. In the case of F5s we have Virtual Editions so we're paying for the hardware to run it on top of the several thousand dollar licenses that are required for each pair and we currently have a pair of F5s per client so there's a huge potential for cost savings there.
      • Requires our network engineers to learn a new skill or our Systems engineers to take on the responsibility of managing the load balancers. It's not a huge difference either way, but it does impact the way we have done business in the past.
