While small devices can technically do TLS, it’s a significant battery drain because of the acknowledgements (keeping the radio on while waiting). Anything battery powered is likely to eschew TLS for DTLS 1.2 + CID or TLS 1.3 with early data. FWIW, Proxylity supports plain UDP as well as DTLS so it’s possible to build a paas-through proxy for DTLS to Lambda, for example. But then you’ll need to implement DTLS in Lambda. People have done it, but it’s a heavy lift. The idea with the DTLS support is protecting content in traffic, and the handling it in your own AWS account. For some cases it isn’t acceptable to have Proxylity or AWS to have any chance to seeing the data. But for the most it’s not a problem and the convenience of what the service provides is worth it. But I hear the concern. I guess I just expect folks will make good decisions for their use cases.
