Appfog, Pagodabox or Heroku are the most re known and used cloud server facility given platforms. This is the most critical situation is to choose the better platform to hosting sites and apps made in different programming language or application software.

I have given some information in this post collecting together hope it will be beneficial.

Appfog

Appfog is may be the mostly featured and mostly used and reliable apps hosting site all over the world. If I give the all features altogether here is these:

Appfog is the multiple service provider for PostgreSQL, PHP, Ruby, Node.js, Java Python, .Net, MySQL, Mongo, 

Appfog is reliable, scalable, fast platform for developing different apps

Ployglot PaaS (Platform as a Service) which contains 2GB RAM free hosted in different area or states in the world

The most common, famous and flexible platform for PHP is phpfog which is made by Appfog

Appfog is completely open source oriented platform

Appfog has so much reliable and usable add-ons to use and apply

Appfog theme: By Developers For Developers

Heroku

Heroku is another most known cloud server apps platform which is professionally used by a large number of professional companies.

Heroku is a PaaS for building, deploying and running cloud apps

Heroku is a has tools for deployment and management

It has a runtime for scalability

It has add-ons system

Manages the entire lifecycle of your deployed applications

Heroku has more and more add-ons to use more and more applications

It is a service provider for Java, Scala, Node.js, Clojure, Python, PHP

Pagodabox

Pagodabox provides object oriented frameworks

It manages web scaling or deploys simply

Rebuild infrastructure with every scale or deploy without any downtime

It has multiple servers which provide continuous service at the time of hardware failure

It has automatic update changes

For Each web instance pagodabox has individual RAM allocation system

It has the history revision system features which provides client to control the previous versions without deleting anything

Pagodabox has the advantage to analysis componentwise

All time concerned about the update and scale the new apps

Manage all codes with GIT or SFTP

We all are acknowledged with web server application and programming. Basically a web application contains the common features/requirements:

HTTP application server

Storage mechanism that is database related task

A template engine

Request Dispatcher

Authentication Module

AJAX Toolkit

Now a days python is one of the most favorable server side programming languages. Many people including the young generations are so much attracted to the python features and its applications. A large number of real projects are going on python all around the world. Web developing software are now drastically oriented to use python.

Scripting, Web Applications, Web Frameworks, Available and huge documentation resources, so much used object oriented applications with a large number of modules, classes, easy interpretation ability, dynamic data types etc are a little list of advantages of using python. Except these, some more features are available in the python like problem solving with easily understanding coding, web development compatibility, easily accessible web development frameworks, micro frameworks etc.

The most common reason to use python is the large number of options to do the web applications and development using its dynamic frameworks and micro frameworks that are available. Different web frameworks and micro frameworks of different categories and having different active features are used by the python lovers of the coding world. All are given below with their features I found roaming into the internet and some blogs.

Basic framework: Basic category python frameworks are: 

AppWsgi, Bottle, Bobo, Cherry.py, circuits.web, PyWebLib, WSGIServlets, PythonPaste etc.

Full-Stack Framework: The most usable full-stack frameworks are:

Django, Web2py Grok, Pylons, TurboGears, Pyramid, Zope, web.py, tornado, werkzeug, whizzy.web, WHIFF etc.

Template Engine Framework: Some frameworks provide template usability. These frameworks act as template engine frameworks. These are: 

Albatross, Aquarium, pyramid, spiked, weblayer, Flask etc

Most of the people who work with python web development frameworks prefer to using the full-stack framework Django, Tornado, Web2py. Some like cherry.py. Some prefer to doing their tasks using the micro frameworks like bottle, flask. Micro frameworks are easier to work with. There are many mind concepts collision selecting which is the better frameworks between the python lovers. Each framework contains special category to work and feature compatibility. According to the necessity of the python user and developer people use particular framework.

Django is most usable and mostly preferable full-stack framework of python. Full stack is called as they have all the basic components to use all functionality and features. Special features that Django has are:

Django needs small code and less time to finish and execute any specific task

Django is the only framework that make a web related task with minimum hazards and maximum web applications facility

Django is mainstream provider

Django always follows standard MVC architecture

A lots of documentations and tutorials with real project examples are available in the internet and this is the only things for the beginners to cop up and learn new web framework Django

A large number of projects are available in the open source market

Web2py is another most demanding lightweight web framework. Web2py is used by many professionals besides Django. Web2py features are:

Web2py is completely used by web server

Web2py is a good python interpreter 

It is web based IDE

It has a good feature with jQuery ingtegration

Web2py provides a good AJAX support

A good support for the database abstraction of layers and database administration

Web2py has the most powerful and flexible coding

It is WSGI compliant

Cherry.py is mostly used for its maturity. Besides this the most available features are:

Cherry.py is a lightweight framework

It is a complete mature framework according to the professional web developers

It does not impose ORM, MVC, templating engine

When changes are detected Cherry.py redeploys it automatically

Tornado is a one of the popular low level frameworks. Tornado is comparatively fast, efficient and easy to work in the case of REST full API.

Werkzeug is another popular low level framework. 

Werkzeug autoreload the apps and web tasks.

This contains the library for wrappers on request/response

Werkzeug has nice handlings for WSGI apps

Werkzeug has great development server

Werkzeug contributes modules for session management

Jinja2  works as template engine. It is mostly flexible for the Django templates.

Sqlalchamey is better for the database management work. It is best ORM/expressions builder around the python world. It can run so far, circles around the django's ORM.

Both Pyramid and Pylons project integrates several different components. Pyramid is more flexible than Django.
