 - Consider [asynchronous polling patterns](https://docs.microsoft.com/azure/architecture/patterns/async-request-reply) for long-running operations to free up connection resources for other operations.
 - Long-lived flows (for example TCP connections being reused) should use TCP keepalives or application layer keepalives to avoid intermediate systems timing out.
 - Graceful [retry patterns](https://docs.microsoft.com/azure/architecture/patterns/retry) should be used to avoid aggressive retries/bursts during transient failure or failure recovery.
-Creating a new TCP connection for every HTTP operation (also known as "atomic connections") is an anti-pattern.  Atomic connections will prevent your application from scaling well and waste resources unneccessarily.  Always pipeline multiple operations into the same connection.  Your application will benefit in transaction speed and resource costs due to reduced overhead of TCP connections being set up and torn down.  When your application uses transport layer encryption (for example TLS), there is also significant cost associated with the processing of new connections.  Review [Azure Cloud Design Patterns](https://docs.microsoft.com/azure/architecture/patterns/) for additional best practice patterns.
