Proximity Placement Groups – Make your Azure VM faster

🔹 Feature: Proximity Placement Groups  

🔹 What It Does: Ensures that your Azure VMs and VM Scale Sets (VMSS) are placed physically close to each other in the same data center, reducing latency up to 50 times.

What is it giving you:

✅ Boost Application Performance: Dramatically improve App Server ↔ SQL Server speed—up to 10x faster query execution.  

✅ Low-Latency Communication: Ideal for high-performance workloads requiring minimal network hops.  

✅ Test Performance Gains: Validate latency and throughput with tools like Latte or SockPerf (https://learn.microsoft.com/en-us/azure/virtual-network/virtual-network-test-latency?tabs=linux).

✅ Enhanced Networking: Combine with Accelerated Networking for maximum performance benefits.  

⚠️ VM-Only Capability: Not available for PaaS services—Azure SQL or even Managed Instance cannot match VM performance in these scenarios.
