We purchased the load balancer for use with an new web app initially. But, we use is for many other servers too. Our goal was to reduce downtime if a server failed and also balance the load across servers so one server would not be over tasked, thus increasing performance. We also wanted it so that we could do maintenance, patches, and updates on one server and still maintain access to services. It is being used organization wide.
  • Provide High Availability.
  • Reduce downtime due to hardware or software failure.
  • Allow for maintenance periods for IT without affecting end users access.
  • Increase performance of services by distributing the load across more than one server.
  • We also use the load balancer as a redirect server for web applications. When these are set up they show a red x like the services are down. I would like for them to have a setting made in future firmware to simply remove the status on redirects.
  • I would also like for them to do on-demand online training for the load balancer like they already offer for free on many of their products.
It works as we expected in our environment. It is great for high availability, redirects, and distributing loads across multiple servers.
  • Positive impact: We can now do server maintenance without disrupting services to the end users.
  • Positive impact: It keeps our servers from getting overloaded during peak utilization times.
  • Positive impact: If we have one server fail the load is shifted to the server that is up to reduce downtime.
We chose Barracuda because we already have other products of theirs. And primarily for the support. Their support is the best we have come across. They help you every step form setup to use to troubleshooting.
It is a good product and the support is very helpful.
  • High Availability
  • Load Distribution
  • Allows for upgrade without downtime
It is a product we plan on continuing to use.
It is fairly easy to learn after support helps you set it up and shows you how things work. Which they will do.

Basic load balancer

We got these load balancers to balance our Exchange 2010 and BSF and a few other services. They worked well for a period of time, but the service over time degraded. We upgraded to F5 which has been working really well.
  • Individualized services
  • Basic load balancing
  • Logging and reporting
  • In-depth customization
  • Detailed look into inspections of packet flow
  • Separation of node and services for reuse
Barracuda Load Balancer is well suited for small environments with little need for load balancing. It is good for a focused purpose.
  • Low cost and lasted 5 years
  • Balanced email and email services fairly well
The Barracuda Load Balancer is a basic load balancer while the F5 is an application delivery system with full networking capabilities.
It did well for basic needs but would not deliver for all our services.

We implemented the Barracuda Load Balancer to provide redundant load balancing in our exchange environment. We currently have 3 exchange servers in a DAG setup. Most of our employees use Outlook Web Access to access their email externally so we wanted to ensure high uptime and good performance across the board.
  • Excellent Load Balancing.
  • Flexible configuration - It's very simple to configure and powerful enough to handle many more websites than just our exchange site.
  • Continuously updated - Barracuda makes fairly frequent updates to address issues and improve features.
  • The interface for identifying the physical ports is not as intuitive as it could be. It can take physical documentation to make sense of it when you have not worked on it for some time.
  • Renewals are a bit on the pricey side. With Barracuda you generally have two renewals. One for the updates and one for Instant Replacement which for something like this you really want to have.
For an important high availability website such as for email, this is a great solution. However, it does in a way, create it's own single point of failure in that if it goes down all the web servers it services are no longer available but there are ways around that rather than just spending more on a secondary unit. There are probably less expensive units or DNS methods you could use for less critical web sites you are trying to maintain. But for exchange and multiple website support with excellent reliability and support, this is a good solution.
  • It has allowed us to maintain a very high level of uptime.
  • It has allowed us to perform server updates without the downtime of services.
  • It has provided a consistent user experience by properly balancing service loads across servers.
Barracuda, in general, has very responsive and high-quality support. It's fantastic to be able to get someone on the phone quickly when you need help or a fast call back. With instant replacement, you can feel assured that in the case of a complete failure, you will have a new unit with configuration intact within a day or two. One of the best for support in my experience.

We use our Barracuda Load Balancer to load balance both our VDI and Exchange traffic. All traffic for both these services go through the load balancer.
  • It provides real time monitoring of each server being load balanced, and will show an alert if something goes offline.
  • It allows one to put a server or service in maintenance mode in preparation for planned maintenance.
  • Overall, there are no issues. It just runs.
It works well with our Exchange 2016 environment, allowing us to manage SMTP, IMAP, and POP3 as separate services. We also use it with our VMware Horizon View security servers.
  • It was a prerequisite for moving to Microsoft Exchange 2016, which requires a load balancer solution as part of the design. So, it allowed us to move forward with that upgrade. Having it to load balance VDI sessions is a bonus.
We did not seriously evaluate any other products. We have had a Barracuda Spam Firewall for many years, and that has been amazing. This seemed like a good choice as well.

We are currently using our Barracuda Load Balancer for both Sharepoint and Exchange traffic balancing and also using it as a reverse proxy service. The load balancer allows us to both balance traffic for both Sharepoint and Exchange and also helps us to perform maintenance on the servers without user downtime. The reverse proxy features have worked well as we transition away from Microsoft TMG servers that are no longer supported. This dual functionality has helped with both our high availability and has helped us to eliminate the old TMG servers. We are currently planning adding additional web traffic balancing and also integrating it with our vdi environment.
  • The reporting and interface to configure the load balancer are detailed but still intuitive and easy to manage.
  • The configuration wizards, along with Barracuda's listing of configuration templates/instructions on their support page, make configuration relatively quick and easy.
  • Reporting allows us to easily monitor our workloads, which the load balancer has been handling without any issues or slowdowns. We also had no problems setting the load balancer to export logs to our central logging solution.
  • The couple of times that we needed assistance, support was extremely efficient and helpful. I really like that i can go online, open a ticket, and schedule a time for support to call me.
  • The configuration settings are relatively granular, but instructions often only list the necessary fields, so if you need some custom settings it can be a little hunt and find what you need.
  • Their support knowledge base page has instructions, but it can be difficult to navigate. There are different versions for different generations of both the barracuda devices and also the connecting software. (looking for setting up the Microsoft Exchange Load balancing can get you different instructions for each level of load balancer and also each version of Exchange).
  • The internal logging review screens and settings can take a while to get used to how it is structured. It can also take a few tries to configure the service logging to get the type of information you'd like.
Barracuda is an inexpensive solution for load balancing web traffic of all kinds and works as a reverse proxy if you need one. It is efficient and has been a very stable solution. If you need extremely granular configuration for your load balancing traffic, then you may need to go with one of the bigger brands. Barracuda will more than handle regular small and medium business use and do so at a greatly reduced price point.
  • Barracuda has allowed us to get the load balancing we needed for Sharepoint and Exchange traffic (replaced Microsoft NLB and DNS round robin) and we were able to get 2 devices (set in high availability) for close to what the other bigger load balancing companies were offereing for 1 device.
  • Barracuda also replaced our TMG reverse proxy for a couple separate web services. The TMG's were out of support and we needed a solution to replace them. When looking we saw that Barracuda could do the work and in a day we were able to set them up. This saved us from having to find a separate reverse proxy solution and helped eliminate 2 other devices.
  • It has also saved us in after hours work, as we can take a portion of Sharepoint or Exchange offline to update and patch servers during the normal day.
We also had looked at Kemp and F5. The Kemp and F5 had a lot of horsepower and advanced configuration and functionality. When we looked at our workload and how we were planning on using the load balancers, we really didn't need all those extra bells and whistles. Barracuda provided all the standard functionality we needed and were looking for and did so at a greatly reduced price point.
