WSGI server vs Web Server - chrisdb - Apr-24-2019 Hello everyone, I've been trying to get into the concept of wsgi, but I still got some questions: - from wat I can tell most wsgi servers are also http servers? - can I run a wsgi server, without using a web server to run a webapp (i.e. run an angular spa with a rest api in flask with waitress alone)? - what are the advantages of using a web server in combination with a wsgi server thank you RE: WSGI server vs Web Server - heiner55 - May-26-2019 can I run a wsgi server, without using a web server to run a webapp: Yes, you can. RE: WSGI server vs Web Server - Skaperen - May-26-2019 i am doing my web stuff "in the cloud" ... specifically at AWS. S3 is, effectively, i nice low cost web server. but, it's static, and has to be front-ended to do HTTPS. i had to split things between a static server and a dynamic server. so, my domains have multiple host names, some going to S3, some going to a server running in an instance, both using CloudFront for caching. there are names like www.example.com, images.example.com, submit.example.com, downloads.example.com. RE: WSGI server vs Web Server - heiner55 - May-26-2019 What does your server cost at maximum (runs 24h, 30 day)? RE: WSGI server vs Web Server - Skaperen - May-26-2019 i'd have to work it out. i do other stuff there, too, like various backups, multiple domains, cloud automation testing, stuff for one of my clients. even then, i'm often under $10 total, per month, not counting some domain registration i have, there. RE: WSGI server vs Web Server - heiner55 - May-26-2019 Thank you.

If want to share with the world then get a host and then leave development server and then eg go for good option like Gunicorn and Nginx. Look at this post for host recommendations. WSGI Servers for a little history. As a note there no need to dig into WSGI specification,unless you want build yet another Python web-framework. fullstackpython Wrote:WSGI is by design a simple standard interface for running Python code. RE: WSGI server vs Web Server - Skaperen - May-27-2019 why can't you just set up the wsgi container to listen to ports 80/443 directly and reduce the total workload on your server and increase the response time? and i have already written my own little http server and am curious how much work would be involved to add wsgi support to it (not as the proxy). edit: that little http server i wrote is entirely in python. i wrote it back before i did anything with python3 (which is now the only python version i write for) and i have not updated it, yet. so i guess that means it is currently a python2 thing. its design is to use the http request path to find a python file and it loads it as a module and runs it in the same process. it is not a multi-user server. edit: the apache server and many others support the cgi method of dynamic execution. to execute python code, the code will have to be a command which runs in a separate process which exits when complete, making for a lower performing server. this includes the disadvantage of the need to store persistent data in files (and probably deal with process sharing issues) or in a database that a new connection needs to be made to for each dynamic web request.

But when i advice what people should use i mention Gunicorn which is a production ready fast WSGI HTTP Server. With NGIX(not Apache in my option) in front for Proxy Requests. I also mention AWS in link i posted,for not messing with server stuff talked about over at all. Can re-post it here: Not messing with server setup AWS Lambda AWS Lambda Wrote:AWS Lambda lets you run code without provisioning or managing servers.For Python setup is Zappa good. zappa Wrote:Never Worry About Web Hosting Again (May-27-2019, 12:32 AM)Skaperen Wrote: the apache server and many others support the cgi method of dynamic execution.Apache will i not use when Nginx is a better and easier to use in my option,CGI is dead in Python it will be removed in the future PEP 594. CGI was never a good solution for Python in the future,that's why Python community did write an all Python solution PEP 3333(WSGI).
