 :::warning
 We recommend using a connection pooler (like [Prisma Accelerate](https://www.prisma.io/accelerate)) to manage database connections efficiently.
 
-If you choose not to use one, **avoid** instantiating `PrismaClient` globally in long-lived environments. Instead, create and dispose of the client per request to prevent exhausting your database connections.
+If you choose not to use one, in long-lived environments (for example, a Node.js server) instantiate a single `PrismaClient` and reuse it across requests to avoid exhausting database connections. In serverless environments or when using a pooler (for example, Accelerate), creating a client per request is acceptable.
