Microservices are often praised for their ability to allow each feature to grow independently, but B2B businesses often face unique traffic disparities among their users. This article introduces pool architecture as a simpler solution for scaling to meet the needs of each client. The concept is compared to a fish tank, where each client represents a fish and shares the same infrastructure. With pool architecture, each client has its own dedicated monolith, allowing for tailored scaling and better resource allocation. This approach offers benefits such as cost optimization, easy infrastructure removal for churned clients, localized incident impacts, increased security/privacy, and simplified deployment compared to microservices.
