Just documenting docs, articles, and discussion related to gRPC and load balancing.

https://github.com/grpc/grpc/blob/master/doc/load-balancing.md

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.

# - run: split -l 1000 orig.json orig-split


export ESINDEX="$1"    #ES index name
export ESTYPE="$2"     #ES document type name
JSONFILE="$3" #JSON file path name. One doc per line.

/*Problem: Integration into 3rd party API requires IP whitelisting. Servers are dynamically started and stopped.

Solution: assign predefined EIPs to EC2 instances as the Auto Scaling group size increases
Limitations: Need to predefine and preallocate all IP addresses
Other possible solutions:
  1) Proxy all requests through single NAT instance
    i. limitation: single point of failure
    ii. need similar solution to make sure NAT is highly available
  2) Remove whitelisting requirement
    i. no...just no ... not gonna happen
