isolation

Single-tenant and multi-tenant SaaS architectures differ in how resources are shared and isolated. In a single-tenant architecture, each customer has their own dedicated instance of the software, which provides maximum customization and control but can be more expensive. On the other hand, a multi-tenant architecture allows multiple customers to share a single instance of the software, leading to cost savings but potentially sacrificing customization. Multi-tenant architectures also require stronger isolation mechanisms to ensure data privacy and security.
