Why are container-based multi-instance systems best suited for products where users mostly work independently?
Why are container-based multi-instance systems best suited for products where users mostly work independently?
- Because they offer high levels of data sharing among users
- Because they are cost-effective for business products
- Because they require minimal adaptation to customer needs
- Because each user has an isolated version of the software and database (correct)
