The communication trend has changed with the internet opening up the communication channel and web-based live chat applications exploiting its capabilities. Traditional SMS conversations have now become obsolete and the USP for live chat service providers is no longer the cost of the message sent but instead the effectiveness and experience delivered by their chat application.
Messaging protocols like WebSockets and XMPP are two of the most widely used instant messaging protocols in the market - being used by messaging apps like Whatsapp, Telegram, and Hike.
If you are planning to launch a live chat application, then read along till the end to discover:
Understanding XMPP and WebSockets:
To put it bluntly, XMPP and WebSockets are communication protocols that allow machines to communicate with each other. These protocols define the 5 key elements of the communication process:
Using XMPP and Websockets the developers do not have to worry about purchasing any cloud storage space for saving any client data as all the data is saved locally on the client devices and the servers are used to act as an intermediate between the chat participants.
Let’s take a deeper look into both XMPP and Websockets to understand them.
How XMPP messaging works
Extensible Messaging and Presence Protocol (XMPP) originally referred to as Jabber, is one of the most preferred choices for building a real-time chat application - mostly because it is open source, and extensible. Developed and maintained by the Jabber open source community, XMPP servers provide their own cloud storage with no limits of chat participants.
Some famous chat applications built on XMPP includes Google talk (now deprecated) and Whatsapp.
To develop a chat application using XMPP, you will need the following resources:
XMPP uses XML to exchange data between client and server. Whenever a client connects to an XMPP server using a chat application, they transmit information with each other which is also known as an XML “Stanza”. Stanza is a basic unit of communication in XMPP.
In an XMPP based communication, there are 3 types of Stanzas:
Based on a decentralized architecture, XMPP based communications assign a unique address (XMPP address), that consists of an IP address, Domain name, and username to all the users in a chat for processing the communication channel. The data is further binded with a secure transport layer such as TCP/IP or HTTP before it is exchanged between the users.

How Websockets messaging works
The WebSocket messaging protocol is built to support full-duplex communication between a client application and the communication server. With WebSockets, the data is sent and received in real-time over a TCP connection, between two or more peers.
Being able to support a full duplex connection, WebSocket based connections are also termed as a persistent (or always on) connection and data can be shared between two client applications without the need of any request by the recipient.
Websocket communication works as follows:

Which one should you pick?
As we reach towards drawing out a conclusion, it is quite clear that both XMPP and WebSockets are two different approaches to setting up a chat application. While XMPP assures rich security and lacks speed, WebSockets delivers the complete opposite. What you choose among the two must always depend upon your business model.
