One of the fun / cool things about Perl is that it can easily inhabit that space between "too complex for bash" and "too insignificant to invest in a C implementation." In my opinion a lot of the command line tools for EC2 are pretty terrible - they have a large learning curve, a high amount of dependencies and they just aren't that easy to get up and going.
So I started by thinking what was the "minimum viable product" for an EC2 client? Something that slaps a valid v2 AWS signature on any arbitrary API request and translates the XML returned into a Perl data structure. And that's exactly what Net::EC2::Tiny is.
In the spirit of *::Tiny modules, I tried to restrict the number of dependencies, but when I decided firmly to require HTTPS support, that locked me into IO::Socket::SSL and Net::SSLeay, so I opted to give myself a little bit of sugar and used Moo. So there's 5 non-core dependencies.
Anyway, when you're in the mood for a quick (and possibly dirty) EC2 client, whip up a simple(ish) script using Net::EC2::Tiny. It's the low learning curve glue between the raw EC2 API and Perl - perfect for those jobs which interact with EC2 in a relatively minor way.
