The term ‘multitenancy’ refers to a software architecture where a single instance of an application serves multiple users or clients, known as tenants. Each tenant's data is isolated and remains invisible to others, ensuring privacy and security. This approach is commonly used in cloud services, offering cost-efficiency and scalability as resources can be shared among multiple clients. Multitenancy allows businesses to leverage cloud infrastructure without the need for separate applications for each client, simplifying updates and maintenance while maximizing economic benefits.
