Get More from Your Azure VMs with Newer Es_v4 Series VMs Featuring 2nd Gen Intel® Xeon® Scalable Processors
After selecting Microsoft Azure to host your multi-tiered Kubernetes-managed web applications in the cloud, another decision remains: Which type of VM best suits your organization’s needs? If you run memory intensive workloads such as relational databases, Azure E-series offer memory-optimized VMs to handle this type of work. Within the E-series, Microsoft Azure offers older Es_v3 Series VMs and a new Es_v4 Series that features newer processors-both at the same cost. Tests show that selecting newer memory-optimized Azure E-series VMs enabled by 2nd Gen Intel® Xeon® Scalable processors can help your organization handle more users accessing Kubernetes-based web apps per VM to deliver a better overall value at small and medium VM sizes.
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 Wv Users, the maximum number of simulated users the application instances support.
In two series of Weathervane tests comparing clusters comprised of two sizes of Azure VMs, newer Es_v4 VMs enabled by 2nd Gen Intel Xeon Scalable processors supported up to 1.77x the number of web app users as older Es_v3 VMs.
For your Kubernetes-based application needs, choose newer Azure E-series VMs enabled by 2nd Gen Intel Xeon Scalable processors, and get up to 1.77x the performance for the same cost.
Handle More Web App Users on Small VMs
If your organization hosts smaller websites with less traffic (such as internal employee portals), small-sized VMs with lower vCPU counts can meet your needs. In tests using the application-level Kubernetes benchmark Weathervane 2.0, which determines the number of simulated users that can comfortably access web apps on VMs while meeting Quality of Service (QoS) guidelines, newer E-series VMs significantly outperformed older E-series VMs.
As Figure 1 shows, in tests comparing the Weathervane performance of Kubernetes clusters made of small VMs with eight vCPUs, Azure Es_v4 VMs enabled by 2nd Gen Intel Xeon Scalable processors handled 1.48x as many users as Es_v3 VM running on older processors. Because Es_v3 and Es_v4 VMs cost the same, selecting new Es_v4 VMs offer a better overall value, ultimately reducing the number of cloud VMs your organization must support.

Handle More Web App Users on Medium VMs
Websites that are accessible to the public require more backing resources to handle a larger traffic load. For medium VMs, hosting Kubernetes-based websites on clusters built from Azure E-series VMs, you can get better performance by selecting newer Es_v4 VMs enabled by 2nd Gen Intel® Xeon® Scalable processors rather than older Es_v3 VMs.
As Figure 2 shows, when configuring Kubernetes clusters with 16 vCPUs per VM, Azure Es_v4 VMs enabled by Intel Xeon Scalable processors supported 1.77x as many Weathervane users as Es_v3 VMs with older processors. Again, as with the small VM series, the older and newer E-series VMs are available at the same cost, which means selecting new Es_v4 VMs can provide better value for your dollar.

Whether the web apps your organization hosts see small or medium numbers of users, choosing newer Es_v4 VMs enabled by 2nd Gen Intel Xeon Scalable processors can allow you to support more visitors to your Kubernetes-based sites.
