Why Mirrorfly Provide Chat Storage in Both Server-Side and Client-Side Database?

You might have heard the word “Slack” where the startups and small businesses of the world are dominated. The demand for online communication across the business and workplace brings the entire collaboration in one place. The necessity of live community interaction takes to rely on different platforms providing group chat or channel based on the number of users.

Most of the web chat providers for collaboration in the market like Slack, Hipchat are built on the server-side database where the messages sent are stored in the server database. This results in storage of a vast amount of data in the server-side data storage.

On the other hand, the client-side database is quite effective in minimizing the data stored in the database by holding the data within the device. This underpinning of development is carried in Mirrorfly infrastructure for diminishing the queuing of messages and consumption of data.

These servers scenario variations are taken place during the development of group chat applications under concurrent users. To make this much understandable, let us have a brief comparison between Client-side database storage and Server-side database storage in group chat applications.

Comparison On Client-side Database Storage Vs Server-side Database Storage in Group Chat Applications

Server Side Database

The rendering of web pages, push notification are performed at a real-time where relaying of minimum messages is carried.

Retrieval of message history within the group chat application is not achievable where the community is an open group.

This consumes a huge amount of storage when it comes to withholding concurrent users within the group chat application.

Client Side Database

The browser support delivers a massive number of messages at an actual rate.

The access of messages within a group or channel exceeding 500 members is achievable in client-side data storage development.

Storing of data such as messages from concurrent users are carried within the client-server even during the user is offline.

Chat Server Side Database

The data transmission between the client and server is processed with a single token key. Here the server-side scripts run on the server instead of the client-side server in order to deliver the content (message) in response to the action carried in the user device.

The illustration explains the message transmission flow where the servers serve transmission of data to the client device by accessing the token keys. Further, the client device sends the request to multiple servers to access the message with the client-side token key.

Most of the group chat applications are relying on server protocols such as MUC and Pubsub to achieve concurrent user base. Both the servers, server-side database and client-side database storage provide access to the data where server-side database is partial and client side database storage access is completely open under a secure environment. Let us discuss the architecture of MUC and Pubsub used in service-to-service communication in group chat applications

End-to-end Understanding of Multi-user Chat and Pubsub Server Components

Both the servers components offer real-time group chat functionality inside a virtual room. Mirrorfly ensures participation of concurrent users within the group is clustered with Pub Sub component for better interaction collaboration among the users.

The MUC component enables to take control of administration and accessibility under a group or community of about 1000+ members. Both the server components, MUC and Pubsub provides end-users to create N number of chat groups and channels where the group restriction is not a complex one.

When it comes to the security breach on MUC component, it serves the highest degree of security layer to messages when the user base limit is under 1000+. Once the concurrent users’ range exceeds 10 Lakhs within the group chat room, Pubsub ensures the content within the chat room is secure from unauthorized access.

When the users participation ranges more than 1 Lakh, MUC based chat group becomes open and accessible to others. Pubsub makes the content available in the client server when the users are offline, thus to render messages to users at a faster rate.This helps in relaying of messages instantly to the right group at right time with the reduction of data consumption.


Every server is designed in such a way to perform the required process of transmitting and rendering of group chat applications. In this trend of real-time and instant collaboration in business and enterprises, group chat application has its own demand across industries. Most enterprises urge to develop chat group applications on their own on-prem infrastructure to experience concurrent user base for different business applications.
