WhatsApp is among the most popular apps on the planet. Developed by Jan Koum, the application and the company behind the application were brought over by Facebook in 2014. With a daily volume of well over 50 billion messages, it is by far the most used app and has disrupted the entire telecommunication industry by making mediums like SMS obsolete by carrying data over the internet in a fast and encrypted manner. With the market for messaging apps expanding, it has also increased the demand for chat app development amidst budding businesses.
What makes this simple app so popular and how does it operate with such efficiency? Let’s find out:
WhatsApp is one of the first apps to have moved away from email id-based registration to phone number based registrations. This simple strategy has allowed it to curb the number of fake users and also allows to verify users using an OTP that is sent to their phones.
2. Data transfer
It works on the Ejabberd (XMPP) server. The Extensible Messaging and Presence Protocol (XMPP) allow data streaming in real time between any two or more network-aware entities. This server enables message transfer between users on a real-time basis. With smooth data processing and high reliability, messages get transmitted on WhatsApp even under peak traffic. Media content is transferred through an HTTP server that is sent to the user with a link-embedded thumbnail.
3. Database management
WhatsApp works on Mnesia DB that handles database management. It is a multi-user DBMS which helps achieve quicker request responses thereby improving the overall efficiency of the database management operation for the application.
4. End-to-end encryption
End-to-end encryption is one of WhatsApp’s major USPs. The app carries out the encryption on the phone and sends it across to the server. The decryption is carried out at the receiver’s end using a key that is unique to your phone.
The XMPP protocol queues the messages on the server where it waits until the intended recipient connects. As soon as the recipient is online, the message is delivered and a confirmation of the same is sent back to the sender. Upon delivery of the message, the information is deleted from the server. This helps the app reduce the usage of the server’s memory and transfers all the ownership of the data to the user.
