An elastic database pool can help you to achieve the following:
- Simplify performance management for multiple databases, especially when usage patterns are unpredictable
- Reduce the cost of multiple databases and provide a convenient way to control the budget
- Perfect choice for Software as a service (SaaS) apps that provision a single database per tenant, to get isolation benefits
It's not recommended to use elastic database pools for mission critical applications that require specific consumption and can be degraded by other databases running in the same pool.
