How to Reduce Your Cloud Spend with High Availability Zonal Load Balancing (HAZL)

It’s been a bit over a year since Linkerd released High Availability Zonal Load Balancer (HAZL), a feature that allows enterprises to reduce cloud spending while still preserving reliability. 

This feature lets you take full advantage of your multizone clusters’ ability to maintain availability even in the face of hardware or network failures, while also minimizing the cross-zone traffic that can cost real dollars. We’ve talked about this topic before on Service Mesh Academy, but with rising cloud costs, we figured it was time to revisit. 

As always, we will finish with a live workshop that lays it all out.  Join us to get your hands dirty and see how it all comes together!

‍

• How multizone clusters work and what benefits they can provide
• Why it is critical to pay attention to cross-zone traffic
• Tools that Kubernetes provides to manage them (or not!)
• How HAZL works, how your enterprise can benefit, and how to use it in the real world.

This is a hands-on workshop, so it's important that you arrive prepared with a Kubernetes cluster (pretty much any kind will do!) and the Linkerd CLI installed on your machine! We'll use BEL 2.18, but edge releases starting with edge-25.4.4. will work just fine, too. Check out the BEL Getting Started Guide for specific instructions on how to set that up. (If you don't want to do the hands-on portion, you are welcome to just listen in. But it won't be as fun!)
