Azure Proximity Placement Groups

Overview

Azure Proximity Placement Groups help improve the performance of applications by reducing latency between virtual machines. They ensure that the VMs are physically located close to each other within the Azure datacenter, thereby minimizing network latency and enhancing application performance. This feature is particularly useful for applications that require low latency and high throughput, such as high-performance computing (HPC) and financial services applications.

Core Functionality

• Low Latency: Ensures that virtual machines within the same proximity placement group are physically close to each other, reducing network latency and improving application performance.
• Improved Performance: Enhances the performance of latency-sensitive applications by minimizing the distance between VMs, which is crucial for applications requiring high-speed communication.
• Easy Configuration: Simple to set up and manage within the Azure portal. Proximity placement groups can be assigned to new or existing virtual machines with just a few clicks.
• Integration with Azure Services: Works seamlessly with other Azure services, such as Virtual Machine Scale Sets and Availability Sets, to provide a comprehensive solution for low-latency applications.

Pricing

There is no additional cost for using Azure Proximity Placement Groups. The pricing for virtual machines and other associated resources remains the same. However, it’s essential to consider the potential increase in costs due to the need for multiple virtual machines and other resources required to support high-performance applications.
