Can you elaborate on the downsides? What makes elixir not well suited for lambda? If you boot the erlang VM in the node.js module initialization it is plenty fast and you can avoid the VM boot tax. I can get < 10ms response times with my prototype.
The upsides are that you can use elixir’s great syntax, and you don’t have to pay for a server waiting around for stuff to do for spiky workloads or very low transaction rates. the HA of Lambda is a big win not to mention avoiding all the hassle of updating/patching another set of server’s operating systems.
