Get More from Your AWS Investment by Selecting Newer R5n Instances Featuring 2nd Gen Intel® Xeon® Scalable Processors
Companies that use the cloud to host their Kubernetes-based websites have a number of choices, and they get the best value when they use the most appropriate instance for the task at hand. To support more of the users who expect consistent access your company’s websites, select a newer AWS R5n instance type enabled by 2nd Gen Intel® Xeon® Scalable processors.
Kubernetes is a platform for deploying and managing application containers, software units that include all components necessary to run applications, such as the application code, libraries, binaries, configuration files, and dependencies. Weathervane 2.0 is an application-level Kubernetes benchmark from VMware.
It uses a real-time auction web app to determine how well a Kubernetes cluster can perform, and delivers results in terms of WvUsers, the maximum number of simulated users the application instances support.
In Weathervane tests comparing clusters comprising two sizes of AWS Instances, newer R5n Instances enabled by 2nd Gen Intel Xeon Scalable processors supported up to 1.85x the number of users as older R4 Instances.
For your Kubernetes website hosting needs, choose a newer R5n instance enabled by 2nd Gen Intel Xeon Scalable processors.
Measuring Kubernetes Performance with Weathervane
Testing used the application-level Kubernetes benchmark Weathervane 2.0, developed by VMware. The benchmark test outputs results in terms of Weathervane users, or WvUsers. The WvUser metric “represents the maximum number of simulated users that could interact with the application instances without violating the QoS requirements”.
As Figure 1 shows, in tests comparing the Weathervane performance of clusters made up of small instances with eight vCPUs, AWS R5n Instances enabled by Intel Xeon Scalable processors was able to handle 1.85x as many users as an R4 instance using older processors.

Better Performance Per Instance Can Reduce the Number of Instances You Need
If you’ve decided to host your Weathervane websites on a cluster built from AWS R-series instances, you can get better performance by selecting newer R5n instances enabled by 2nd Gen Intel® Xeon® Scalable processors rather than older R4 instances.
Testing also measured the performance of large R5n instances consisting of 32 vCPUs. As Figure 2 above shows, a cluster using large AWS 32-vCPU R5n instances enabled by Intel Xeon Scalable processors supported 1.49x as many users as a cluster with R4 instances using older processors.

Whichever size instances your Weathervane site requires, choosing newer R5n Instances enabled by Intel Xeon Scalable processors could allow you to support more users.
