Whatever cloud-based application you’re developing, you will likely end up using some form of load balancing. The complex task of horizontal scaling increases the capacity of your application, which means that some form of load balancing product inevitably becomes necessary. While your application might not need it now, it will be hard-pressed without load balancing should its needs and demands increase.
Balancing is especially important if you’re considering an enterprise, as load problems are likely one of the first problems you will encounter down the line. The importance of load balancing cannot be understated, but if you remain confused about your needs, read on. We will talk about some questions you need to ask before you decide on a load balancing solution, and why you need to ask them.
1. Is Your Load Balancing Software or Service Capable of Direct Server Return (DSR)?
While DSR comes with its own pros and cons, it is definitely worth considering if your application involves real-time streaming of audio or video. DSR basically allows the server to transport content directly to the client without external processes by intermediaries (outside of hardware). DSR essentially allows a direct line from the server to the user without interfering traffic, whereas content would normally pass through the same pathway that it was requested from.
2. How Good Is the Service’s Health Checking?
One of the ways load balancers determine how to balance and manage the load is by analyzing the current status of the application. That means that checking the software’s health must be as comprehensive as possible to achieve maximum efficiency and effectiveness. It is paramount not just for better performance but also for a constant level of availability.
3. How Does It Implement Persistence?
Persistence is one of the most important concepts in load balancing. It is what ensures a server or instance that all subsequent requests go to that same server/instance once a user has been assigned to it. This is how the user’s session is managed and maintained.
Persistence can come in the form of source IP addresses or cookies. Either has its unique pros and cons, so it is crucial to consult with your provider about what type of persistence they implement.
4. How Do the Connections Manage Bleeding off or Quiescing Off?
Bleeding or quiescing off is when a load balancing service starts distributing requests to specific users while allowing existing users to continue using the application until they are finished. It removes that instance from rotation until all the users are finished. From there, servers and instances can be taken offline either through a manual or automated process.
This enables patching and maintenance of the application in sections even though users are still using the application. In on-demand environments, this can keep costs controlled by only maintaining the active instances necessary for the current demand.
