     3 PyAMS application architecture

     4 ==============================

     5 

     6 PyAMS applications are built on a small set of prerequisites and external components which *can* or, for some of them,

     7 *must* be included, the minimal configuration is:

     8 

     9 * a mandatory shared ZODB;  :ref:`zodb` chapter

    10 

    11 * a Redis or Memcached server, to handle cache and sessions;

    12   :ref:`pyams_cache` chapter

    13 

    14 

    15 Single server deployment

    16 ------------------------

    17 

    18 Overview of the environment system after the :ref:`quickstart` installation.

    19 It's a very lite configuration, with only mandatory resources.

    20 Obviously you can extend this system by connecting more resources like is described in the :ref:`config` chapiter

    27 Development deployment

    28 ------------------------

    29 

    30 In additon of mandatory resource **PyAMS** could work with:

    31 

    32 * a websockets server (GuniCorn), used to handle desktop notifications;

    33   you can find information about this component in the :ref:`pyams_notify` chapter;

    34 

    35 * an Elasticsearch index, used to handle quick and optimized searching.
