This is a quick tutorial on how to test code using the GoMock mocking library and the standard library testing package testing.
GoMock is a mock framework for Go. It enjoys a somewhat official status as part of the github.com/golang organization, integrates well with the built-in testing package, and provides a flexible expectation API.
Just documenting docs, articles, and discussion related to gRPC and load balancing.

Seems gRPC prefers thin client-side load balancing where a client gets a list of connected clients and a load balancing policy from a "load balancer" and then performs client-side load balancing based on the information. However, this could be useful for traditional load banaling approaches in clound deployments.

gRPC "works" in AWS. That is, you can run gRPC services on EC2 nodes and have them connect to other nodes, and everything is fine. If you are using AWS for easy access to hardware then all is fine. What doesn't work is ELB (aka CLB), and ALBs. Neither of these support HTTP/2 (h2c) in a way that gRPC needs.
These are my notes for connecting to a meraki client vpn from ubuntu 16.04. This configuration assumes you are using a psk for the ipsec auth.
Install the following packages:
apt-get install -y strongswan xl2tpd
