TO BE or NOT TO BE – Isolated?
One common question raised while dealing with any SaaS architecture is whether
there needs to be an isolated database for every customer or should there be a
shared database / shared table for all customers.

Decision Parameters
To take a decision you should ask the following questions,• Will my customers be willing to share the data with other
customers or is it a big no?
• Do my customers demand access to the database?
• Will my customers need the option to individually backup and restore the data at any point in time?
• Is the data volume high for all customers?
• Will the workload from all my customers be high and at the same time(concurrency)?
You might not have an option but to provide those customers an isolated database.

• Will my customers be willing to share the data with other customers or is it a big no?
You might need to go for an isolated database.
Having said that please note that it is a very bad practice and a big blunder to open up the data environment to the customer and it is wise to stay away from it.
Usually customers would need data access to backup the data regularly and sync to their on-premise environment or when they need to create their custom reports.
A better way to handle this would be to provide data export files and APIs through which they can sync the data with the on-premise data and as for the custom reports have a custom report builder capability within the product itself.

• Do my customers demand access to the database?
While it is easy to achieve this in a isolated database, you can still achieve this in a shared table by building an utility.

• Will my customers need the option to individually backup and restore the data at any point in time?
You might have to do a capacity planning using workload and storage for your customers and see if combining customers data makes sense from a performance perspective.
In a shared table scenario you typically shard the data based on tenant. If you end up with one shard for each customer then going for a shared table makes no sense.
A shared table scenario makes much sense from a performance perspective only for the following scenarios,
• When you have many customer with lesser or medium volume of data
• When the workload of the customer is spread at different times
• When the data volume and workload pattern is different between different customers

Ideal Option In SaaS
Go for a hybrid model where you completely design for a shared table approach
Expect mixed set of customers with different preferences
Designing for Sharding by Tenants will allow you to achieve hybrid support
Have an option to isolate specific customers on a need basis
