What is Multitenancy? Meaning, architecture, benefits & risks

Multitenancy is an architectural pattern that enables the use of shared infrastructure to serve multiple customers, or tenants, while keeping their data and workloads logically separate. This approach offers significant benefits, such as cost savings, scalability, and simplified updates, as tenants share the same physical resources yet operate in isolated environments. In cloud computing, multitenancy is prevalent in public clouds like AWS and platforms such as Salesforce, where workloads from different tenants are managed on shared infrastructure without compromising data security or performance. The key challenges include managing resource contention, ensuring robust data isolation, and maintaining compliance in regulated industries. Northflank addresses these challenges by providing built-in namespace isolation, RBAC, and secure environments for tenant-specific workloads on Kubernetes, thus helping manage multitenant architectures effectively without extensive manual effort.
