IT teams looking for an HTTP client/server solution for asyncio and Python
About AIOHTTP
Supports both client and server side of HTTP protocol, both client and server web-sockets out-of-the-box, and avoids callback hell and web-server with middlewares and pluggable routing.

asyncio
asyncio is used as a foundation for multiple Python asynchronous frameworks that provide high-performance network and web-servers, database connection libraries, distributed task queues, etc. asyncio is often a perfect fit for IO-bound and high-level structured network code.

Kestrel
Kestrel is a cross-platform web server for ASP.NET Core. Kestrel is the web server that's included and enabled by default in ASP.NET Core project templates. Kestrel supports HTTPS, HTTP/2 (except on macOS), Opaque upgrade used to enable WebSockets, Unix sockets for high performance behind Nginx. Kestrel is supported on all platforms and versions that .NET Core supports. Some browsers require granting explicit permission to trust the local development certificate. Project templates configure apps to run on HTTPS by default and include HTTPS redirection and HSTS support. The Kestrel web server has constraint configuration options that are especially useful in Internet-facing deployments. There's a separate limit for connections that have been upgraded from HTTP or HTTPS to another protocol (for example, on a WebSockets request). The default maximum request body size is 30,000,000 bytes, which is approximately 28.6 MB.

Cowboy
Cowboy is the ultimate server for the modern Web with support for Websocket, HTTP/2 and REST. Cowboy is a small, fast and modern HTTP server for Erlang/OTP. Cowboy aims to provide a complete modern Web stack. This includes HTTP/1.1, HTTP/2, WebSocket, server-sent events and Webmachine-based REST. Cowboy comes with functions for introspection and tracing, enabling developers to know precisely what is happening at any time. Its modular design also easily enables developers to add instrumentation. Cowboy is a high-quality project. It has a small code base, is very efficient (both in latency and memory use) and can easily be embedded in another application. Cowboy is clean Erlang code. It includes hundreds of tests and its code is fully compliant with the Dialyzer. It is also well documented and features a function reference, a user guide and numerous tutorials. Knowledge of the HTTP protocol is recommended but not required, as it will be detailed throughout the guide.

Tornado Web Server
Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user. Tornado is different from most Python web frameworks. It is not based on WSGI, and it is typically run with only one thread per process. While some support of WSGI is available in the tornado.wsgi module, it is not a focus of development and most applications should be written to use Tornado’s own interfaces (such as tornado.web) directly instead of using WSGI. In general, Tornado code is not thread-safe. Tornado is integrated with the standard library asyncio module and shares the same event loop (by default since Tornado 5.0). In general, libraries designed for use with asyncio can be mixed freely with Tornado.
