Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
"The most important features would be the load-balancing of HTTP and TCP requests, according to multiple LB-algorithms (busyness, weighted-busyness, round robin, traffic, etc). Another important feature that we cannot live without is the username/passwd authentication for legacy systems that had none.""The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services.""I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring.""It reduced the load on our main load balancers.""What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks.""The feature that I have found the most valuable is that it works for my use case of application load balancing. I'm using it for PeerSense, and it's easy enough for PeerSense.""Tech support is super-quick to respond, and always on target with answers specific to the current issue.""I estimate that this product has saved our company hundreds, if not thousands, of dollars in possible downtime from previous load balancers. We make a lot of our money from online sales, so it is critical to have 99.9% uptime."

"The tool's mutual TLS stands out. It provides secure communication between services within the cluster. Additionally, Istio offers built-in telemetry and tracing with tools like Jaeger, which aids monitoring and troubleshooting.""The load balancing, service application, and monitoring of the life of the service are valuable features. We use it for authentication of call services, load balancing the calls among the service providers on service instances, and monitoring the health of the services.""We use Istio for Service Discovery and routing traffic.""Istio's best feature is that it's easy to use.""The most valuable features of Istio are the traffic management and the Sidecar they inject, which greatly helps secure the application.""Istio can save you time in terms of network troubleshooting."

More Istio Pros →

"The logging functionality could use improvement, as it is a little cryptic.""Pricing, monitoring, and reports can be improved.""Maybe HAProxy could be more modular.""There are three main areas to improve: 1) Make remote management more modern by adding API. 2) Propose a general HA ​solution for HAProxy (no I'm using keepalived for this). 3) Thread option should be a bit more stable.""HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets.""The basic clustering is not usable in our very specific setup. The clustering is mainly a configuration replication and is great in a case of active-passive usage. In the case of an active-active (or with more than two nodes) where the configuration is not fully identical, it cannot be used as-is.""There is room for improvement in the pricing model. It could be cheaper.""The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."

More HAProxy Cons →

"If you're a beginner in infrastructure management and networking, learning Istio might pose some challenges. However, if you have some knowledge of networking or service meshes, you should find it manageable. Istio's website offers documentation to guide you through learning.""For our use case that we applied it to, there were graph queues and the calls that were coming in. There were the things that we couldn't apply at the time, but it kind of worked.""Istio needs to be more mature and user-friendly.""Istio's documentation is basic and would benefit from more examples.""It would be good if the solution had more community forums.""If someone doesn't understand Kubernetes, they'll have issues working with Istio."

Pricing and Cost Advice
  • "HAProxy is free software. There are optional paid products (support/appliances)."
  • "The price is well worth it. HAProxy Enterprise Edition paid for itself within months, simply due to the resiliency it brings. It was a bit more expensive than we were originally interested in paying, but we are thankful we chose to go with HAProxy."
  • "Very good value for the money. One of the simplest licensing schemes in this category of products."
  • "Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
  • "If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
  • "We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
  • "I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
  • "The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."
  • More HAProxy Pricing and Cost Advice →

  • "It is on the less expensive side. It provides a significant saving for us in terms of cost and other things. It is open-source. We just download it from the open-source framework and use it."
  • "You can deploy Istio free of cost and don't need to pay for it."
  • "We use the tool's open-source version, so there are no hidden fees or additional costs associated with it."

    Reviews from Real Users

    Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES

    “I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.
