When a Software-as-a-Service <\/a>(SaaS) application is ready to move from the initial product (MVP) to a scalable cloud-native architecture<\/a>, one of the key decisions solution architects and technology leaders will have to make is about tenancy.<\/p>\n More specifically: Should you choose a single-tenant or multi-tenant<\/a> application?<\/p>\n The most successful tech businesses those in which application architects understand that technology is an extension of the business model<\/a>. In that sense, a tenancy decision is more a business-driven decision than a technology-driven one. You should consider the context of your business itself, the product usage or revenue expectations and any regulations that companies must comply with.

To help you decide between them, let’s weigh up their distinct security and privacy<\/a> implications, costs, accessibility, and ease of use:<\/p>\n Single-tenant applications are comprised of an architecture where a single tenant, or customer, is served by a single instance of the software application and its supporting infrastructure.<\/p>\n The tenant has a dedicated instance of the database, dedicated server(s), separate interactions and separate access rules\u2014which are collectively kept completely independent from any other tenant.<\/p>\n Some common characteristics of single-tenancy include:<\/p>\n There is one large caveat when it comes to the features mentioned above: As the number of tenants increases, so does the amount of time needed to manage configurations and software updates and keep track of the developers, testers, DevOps<\/a> and cloud resources<\/a>.<\/p>\n That\u2019s when a multi-tenant architecture becomes necessary.<\/p>\n Multitenancy<\/a> is an architecture in which multiple customers are served by a single instance of the software and its supporting infrastructure. Each customer shares the software application and tertiary applications. Based on the specific architecture, business needs and regulatory\/security requirements, multi-tenant applications may separate each tenant’s data in one or more of the following ways:<\/p>\n There are many aspects of building multi-tenant applications to consider and almost all involve complexity. For instance:<\/p>\n Regardless of the type of data isolation you\u2019re using\u2014logical separation, schema-level or physical isolation\u2014multi-tenant architectures require greater expertise and development capability. There is the risk that a certain customer\u2019s data may be exposed or compromised<\/a> via another tenant\u2019s use of application data.<\/p>\n Each update must be tested thoroughly for data security and isolation, performance, security and compliance. Multi-tenant architecture can be a powerful business propeller with a capable team and infrastructure setup.<\/p>\nWhat Are Single-Tenant Applications?<\/span><\/h2>\n
