It would have been nice to actually have a lab that creates Load Balancer. In the Videos we discussed the Cold Potato Premium Routing. Global Cloub Load Balancer and then we moved on to creating the VPC. So there are a few gaps that I would like to fill in for my knowledge.
1. We never actually created the Load Balancer. It would be really nice to have a lab to create and test it.
2. GKE also have load balancing. How does it compare to Global Load Balancing?
3. What is the Role of Unmanaged Instance Group and how does it relate to Load Balancing?
Hello! It might seem a little unexpected in how I do this, but I actually address these questions at 2:40 in this lecture:
I especially suggest that you look at the whooole Cloud Load Balancer structure that GKE sets up for you. Follow the links from one thing to the next so you understand how all of those pieces tie together.
For many of our labs, so far, we’ve been building the pieces up from scratch–but this is a perfect opportunity to see how all of the pieces you need for some functionality (in this case it’s the global load balancer) can often get created for you, automatically, by higher-level services like GKE. But you still have visibility into what you’ve (indirectly) created and you can test it out.
To answer your last question, you can also hook up unmanaged instance groups to the load balancer, if you want to–and that is done in exactly the same way as managed instance groups are connected–but that is something you would only do as a sad concession and not best practice. (
[Y]ou should always create managed instance groups unless your applications require you to group instances together that are not identical.) For this reason, I think you are very unlikely to see this on your ACE exam or in any real-world situation. But if you’re curious, here’s some more documentation on it.
I hope this helps!
Thanks Mattias! I did my research and found the answers I was looking for. As usual thanks for the detailed response. I appreciate it.
Happy to help! 😁
