python - What is the difference between web server component and web server? - No framework -

-

now bear me please. i'll explain beginning briefly. 8 months ago, worked in web project python, used no framework (from scratch). limited myself implement views , templates, pass of months became curious made research.

now i'm checking wsgi , how make "do-it-yourself" frameworks. i'm bit curious things. when in project 8 months ago, used web server, remember in web there "web server" component too.

the component tornado web server, , other server nginx. now, what's difference between 1 , other server?

and if component (tornado or one) not thing need deployment, else need?

to clarify:

tornado python web framework , asynchronous networking library.

that's own definition, not mine. (https://pypi.python.org/pypi/tornado)

tornado can function web server well. python web development frameworks don't function web server - need bootstrapped onto library development work. others can function web server, don't recommend - designed write code, not build it.

if you're inclined so, can serve tornado directly. people - including tornado development team - have seen better performance putting tornado behind nginx , , using nginx load-balance , serve static content. http://www.tornadoweb.org/en/stable/overview.html?highlight=nginx

there many different ways deploy wsgi applications internet. of them include:

  • directly deploy app on port80
  • use nginx/apache public load-balancer:
    • proxy connections app running on local port
    • run app under uwsgi, configure public load-balancer proxy requests uwsgi

there other ways deploy wsgi apps using gunicorn, eventlet, twisted, , countless other networking or web serving libraries.

to answer question :

in project worked on, nginx functioned public facing web server. tornado (most likely) functioned both web framework , private web server.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
