Summary

In this chapter, you have learned about the network services in Google Cloud, how to handle routes and firewall rules, and how to make design decisions around load balancing and hybrid connectivity using GCP. You have also learned some best practices and common network designs, and, very importantly, about the zero trust principle. There is one big takeaway from this chapter: never trust, always verify. The skills you've learned in this chapter will allow you to bake security into your network design, incorporate the right type of load balancing based on your application needs, and make sure multi-project cloud solutions have a centralized, shared VPC, where network policies are set and controlled from one place.

You should now have a robust foundation to start designing networks in Google Cloud that are global, scalable, and able to offer a resilient and secure infrastructure environment for VMs to be deployed on.

Speaking of which, in the next chapter, you...
