 ## What is Multitenancy?
 
-Multitenancy refers to a kind of architecture where a single instance of software runs on a server and serves multiple customers. In a multi-tenant environment, separate customers tap into the same hardware and data storage, creating a dedicated instance for each customer. Each tenant’s data is isolated and remains invisible to others, but is running on the same server.
+Multitenancy, especially in cloud-based systems or software solutions, refers to the ability of a software application or system to serve multiple customers (tenants) simultaneously. While these customers share the same infrastructure and codebase, their data remains separate, and each customer has exclusive access to their own data.
