[OpenSIPS-Users] [OpenSIPS-Devel] [Blog] Running OpenSIPS in the Cloud

We have run OpenSIPS both in Docker containers and in AWS. Scaling can be tricky when dealing with external carriers as many require you to provide the exact IP addresses that will be used beforehand so the scaling is limited to the IPs that were provided.

A note on AWS ELBs is that they only work for TCP traffic. They will not do UDP.

Good info Bogdan / Robert.

I would also be interested to learn of anybody running OpenSIPS in a docker like container service to allows for horizontal automatic scaling.

Nice info. There might be some more complex AWS setups people might want to use, but I really do not know from a telephony architecture if they are viable or useful:

- AWS Nat gateway (basically a NAT for a subnet of AWS instances rather than 1-to-1 NAT instances)
- Use of AWS ELB: AWS can assign multiple IPs to a AWS ELB per explicit request to AWS to allow for scaling the ELB (hence you might have multiple external IPs mapping to your private IP).
- I vaguely remember there are some settings for low latency subnet, maybe called "placement groups"
- I vaguely remember some AMIs are better for low latency (I think AWS makes some)
- Might want to use larger instances to reduce change of instance being shared or directly request dedicated instances or dedicated hosts

Cloud computing is a more and more viable option for running and providing SIP services. The question is how compatible are the SIP services with the Cloud environment ? So let’s have a look at this compatibility from the most sensitive (for SIP protocol) perspective – the IP network topology.......
