What is On Premise Messaging?
On-premises messaging refers to a type of messaging system where the servers and infrastructure for sending, receiving, and storing messages are hosted within an organization’s own physical location or data center. This means that the messaging service is deployed and operated internally, rather than relying on external or cloud-based messaging servers..
What Is an On Premise Chat Software?
On-prem chat solution is a type of communication platform that is installed and hosted locally on your organization’s premises, rather than being hosted on a public cloud platform or remote data center.
This typically means that your business has full control over the infrastructure, hardware, and software applications, including their performance, security, and maintenance.
Why Should You Choose On-premise Chat Solution For Your Business?
Well, there are hundreds of explanations about this deployment option across the internet. But the one question that you’ll need an answer for is – Is on-premise chat solution right for your business?
Let’s rule it out
1️⃣ Enhanced Security
Building a self-hosted private chat server can be your best option if you are looking for enhanced data security for your messenger application.
You will basically have complete control over your data, so you can implement your security protocols to ensure it stays secure.
2️⃣ Customization
Your business is unique and it requires specific chat requirements to deliver the experience your target users expect.
In this case, you can customize or personalize the chat solution as much as you want to meet your specific needs
Guess what? you can also integrate it with other business applications, and add unique features that your users will love.
3️⃣ Compliance with Industry Regulations
If your organization must comply with strict data privacy and security regulations, then hosting your enterprise messaging app on your own can be your ideal choice.
This means, you have full control over your communication data, which can help you meet compliance requirements as per your need.
4️⃣ A Great alternative to cloud-based chat solutions
If you need to build a messenger for business and government, or healthcare organization, financial institution, or indeed a company with legacy systems that cannot be easily integrated with cloud-based chat solutions, then creating your own chatting server would be a wise thing to do.
How Do On-premise Chat Solutions Work?
Setting up an scalable on-premise solution for your dedicated chat apps typically means that you are hosting your app/ software on your own servers that are physically located with your organization’s own premises.
This means that the organization has complete control over the chat solution and the data it generates. So let’s say you have hosted your app on your own server, you can expect the following to happen.
When a user sends a message through the on-premise chat solution, the message is securely transmitted within the organization’s network without leaving the premises.
This ensures that the communication data remains private and secure.
Let me explain how self-hosting work in a few simple steps:
1. Installation
The first step in setting up a server on your own premise.
This can typically be done by downloading the software from the vendor’s website and following the installation instructions.
2. Configure the solution as per your brand/ business requirements
Once the software is installed, it needs to be configured to work with the organization’s network and infrastructure.
This can include setting up user accounts, creating channels, and configuring security settings.
3. Register your users
Once the software is installed and configured, users can access it through a web browser or a dedicated app installed on their devices.
They can then log in using their credentials and start using the chat solution to communicate with their colleagues.
4. Access app data from your own servers
All communication data generated through the ready-made chat solution is stored on the organization’s servers. This includes messages, files, and other media exchanged between users.
5. Customize the security & privacy of your app
Hosting your platform on-premise typically offers robust security features for your chat apps, such as two-factor authentication, encryption, and access controls, to ensure that the communication data remains private and secure.
6. Set up a maintenance routine
As with any software, your chat solution requires ongoing maintenance to ensure that they continue to function properly. This can include applying software updates, monitoring system performance, and addressing any issues or errors that arise.
Benefits Of On-premise Chat Server
Here are some benefits that you will get when hosting your app on your own servers:
❇️ Full Control: You have full control over the installation, data privacy, and security. Since the server is installed on your own premises, you have all the control over its usage and storage.
❇️ Access at Any Time: You can access your data whenever you need to without any restrictions. You won’t have to worry about third-party users accessing your data since it is on your server.
❇️ Private and Secure: When you build your own enterprise messaging infrastructure and host it on your premise so that your chat messages are transferred among clients under your server within your firewall, ensuring your conversations are kept within your secure firewall, and your data is preserved.
❇️ Low Latency: Since your chat app system doesn’t have to traverse time through the cloud, there gap between data exchange is very minimal. This can result in a faster and more efficient communication experience for your app users.
What is an Example of an On-premise Platform?
Some of the popular on-premise solutions include Microsoft Windows Server, VMware vSphere, Oracle Database, Cisco Unified Communications Manager (CUCM), SAP ERP and IBM WebSphere Application ServerMicrosoft Office

What is hosted vs on-premise?
A hosted solution lets you access your app’s data from anywhere, anytime. It can make your systems work as per your convenience. Whereas on-premises data centers are built in the organization’s premises.
