The #SaaS maturity model is broken down into four levels,
Level 1 (Single- #Tenant, Custom Instances)
At this level of the SaaS maturity model, the only way to support multiple customers (tenants) is to provide each of them a separate copy of the software. Because the provided copies can be customized by writing custom code, each customer is required to run a different instance of the software and scalability is non-existent, even though the software is technically delivered as a service.

Level 2 (Single-Tenant, Configurable Instances)
At level 2, software can be customized by changing its configuration instead of writing custom code. In other words, all tenants interact with the same code configured in different ways, with each tenant running their own copy on a separate virtual or physical machine. Consequently, scalability and multi-tenancy are still not achieved.

Level 3 (#Multi_Tenant , Configurable)
The third level of the SaaS maturity model can be described as being almost the perfect case because it includes both configurability and multi-tenancy, allowing each tenant to quickly and efficiently customize the same shared instance through a self-service tool. The only thing missing is scalability because software can be scaled up only by moving it to a more powerful server, which isn’t cost-effective.

Level 4 (Multi-Tenant Configurable & #Scalable)
Level 4 is the highest level of the SaaS maturity model. It combines the configurability and #multi_tenancy of level 3 with scalability, making it possible to transparently add new software instances to the dynamic pool of instances with the help of a load balancer, whose job is to maximize the utilization of storage, processing power and other resources. Each tenant’s data is stored separately, and a virtually infinite number of tenants can be seamlessly accommodated by adjusting the number of servers on the backend to meet the current demand.

What's the difference between #multi_cloud and #hybrid_cloud computing?
Both "multi-cloud" and "hybrid cloud" refer to cloud deployments that integrate more than one cloud. They differ in the kinds of cloud infrastructure they include.
A hybrid cloud infrastructure blends two or more different types of clouds, while multi-cloud blends different clouds of the same type. You might say hybrid cloud is like combining apples and oranges, while multi-cloud is like combining different types of apples.
