Whatsapp mechanism when user is offline

If client B is offline, all the whatsapp messages are queued on the chat server. Until if the clients reconnect to retrieve the message from client A. The messages are wiped from the chat server memory as soon as the client B has accepted the messages. Whatsapp device is communication with the chat server. Chat server is communicating with the users account, profiles and groups etc. In whatsapp, Chat server and both device are communicating with multimedia server. Chat server is also communication with offline storage.

Whatsapp specifications for back-end

Lets talk about the back-end specifications of whatsapp technology. The FreeBSD is an operating system. YAWS is yet another server. Ejabberd is in server application. Erlang is an programming language. XMPP stand for extensible messaging and presence protocol. PHP is the server side scripting language. Mnesia is default database and Encryption RC4 encrypt your data and chats.

1. Ejabberd

Ejabberd server facilitates instant message transfer between two or many users. It brings configurability, scalability and fault tolerance. There are six benefits of Ejabberd – Modern, that support voice, video and apps. Fault tolerant – It has the ability to upgrade the server while running. Massively scalable – It is designed for massively scalability, Manageable – comes with very powerful command line tool. Highly Versatile – offers many customized hooks to adapt it easily to various use cases. Very Modular – Code is extremely modular.

2. XMPP Protocol

It is message oriented middle ware based on XML. XMPP protocol is faster than HTTP protocol only for real time chat application. It is being used by whatsapp technology, as to transfer the messages.

3. Erlang

It is a programming language used to build massively scalable software in real time system. Erlang is used in Banking, Telecom’s, E-commence and instant messaging. It support for concurrency and fault tolerance. Companies that are using Erlang – Whatsapp, Amazon, Yahoo, Facebook, Motorola, Ericsson etc.

4. Mnesia

Its is a multi user distributed database management system. It is the default database of Erlang and distributed, soft real time database management system. Mnesia is written in the Erlang, that is able to achieve quick response and request for improving overall efficiency.

5. FreeBSD

It is an operating system and all the transactions of whatsapp technology goes through FreeBSD operating system. In FreeBSD, there are lots of services in Kernel like memory management, process management and input/output system.

6. YAWS

It stands for yet another web server. It is used to store multimedia files and it is the web server which is written in the Erlang. Speed and scalability are the two major advantages of YAWS.

7. PHP

It stands for Hypertext pre-processor. Regarding PHP integration, there are several ways to communicate both sides. You can integrate your chats apps with PHP code using PEB [Open source PHP extension].

Mochai web

It is an Erlang library for building light weight HTTP server. There are many capabilities of Mochai web – Rendering temp-lets like any HTML pages. Handling post requests and cookies only.

Contus Fly Framework

It is the framework that catalyzes the build of an instant messaging application. It is used to develop whatsapp clone for Android, iOS and Windows. There are three platform to run application of Contus Fly framework which communicating with extensible messaging and presence protocol. XMPP is communicating with Ejabberd server and Ejabberd server communication with different databases. MySQL, Mnesia and Apache Cassandra. MySQL is used for storing of user profile. Mnesia used for storing login session information. Apache Cassandra used for storing information of chat logs.
