GCP	Cloud Blog	5 things you didn’t know about the new Tau VMs	https://cloud.google.com/blog/topics/developers-practitioners/5-things-you-didnt-know-about-new-tau-vms/	things you didn t know about the new Tau VMsGoogle Cloud Compute VMs are built on the same global infrastructure that runs Google s search engine Gmail YouTube and other services And over the years we ve continued to launch more and more Compute family and VMs types to serve your workload needs at the price point you re looking for When you take a bird s eye look at our Compute offerings you ll notice the following family types General Purpose E N ND N Virtual machines well suited when you need a balance between customization performance and total cost of ownership Compute Optimized C CD Performance sensitive workloads where CPU frequency and consistency are required or applications that require more powerful cores and a higher core memory ratios Memory Optimized M M Virtual machines for the largest memory requirements for business critical workloads Accelerator Optimized A These are the highest performance GPUs for ML HPC and massive parallelized computation As their names might suggest each family is optimized for specific workload requirements While they cover use cases like dev test enterprise apps HPC and large in memory databases many customers still have compute requirements for scale out workloads like large scale Java apps web tier applications and data analytics They want focused VM features without breaking the bank or sacrificing developer productivity  The Tau VM family is the new VM family that extends Compute Engine s VM offerings for those looking for cost effective performance for scale out workloads with full x compatibility Check out the official blog post and my video below to get a quick intro to the new Tau VM family and TD its first instance type  If you re like me and still want help understanding when to use TD VMs and how they stack up here are Tau VM facts that should help  TD VMs are built on the latest rd generation AMD EPYCTM processorsAMD EPYC processors are x microprocessors based on AMD s Zen microarchitecture introduced in The third generation Milan came out in March building upon the previous generation with additional compute density and performance for the cloud At our data centers we re able to get more performance per socket per rack and pass that over to workloads running on TD VMs  The AMD EPYC processor based VMs also preserve x compatibility so that you don t need to utilize technical resources and time redesigning applications and instead can immediately take full advantage of x processing speed and ecosystem depth   TD VMs are well suited for cloud native and scale out workloadsCloud native workloads have led to the continued proliferation of distributed architectures Data analytics and media streaming for example often leverage scale out horizontally scalable multi tier architectures That means when additional processing power is needed you can scale out by statically adding or removing resources to meet changing application demands As cluster sizes increase the communication requirements between compute notes rise quickly AMD EPYC processors are built using the Zen architecture which uses a new unified complex design that dramatically reduces core to core and core to cache latencies This reduces communication penalties when you need fast scale out across compute nodes TD VMs offer the ideal combination of performance and price for your scale out workloads including web servers containerized microservices media transcoding and large scale Java applications TD VMs will come in predefined VM shapes with up to vCPUs per VM and GB of memory per vCPU and offer up to Gbps networking TD VMs win against other major cloud providers on absolute performance and price performanceLet s take an example A vCPU VM with GB RAM will be priced at per hour for on demand usage in us central This makes TD the lowest cost solution for scale out workloads with higher absolute performance and higher price performance compared to general purpose VMs of any of the leading public cloud vendors You can check out how we collected these benchmark results and how to reproduce them here Results are based on estimated SPECrate int base run on production VMs of two other leading cloud vendors and pre production Google Cloud Tau VMs using vendor recommended compilers View testing detailshere SPECrate is a trademark of the Standard Performance Evaluation Corporation More information available at www spec org Google Kubernetes Engine support from day oneGoogle Kubernetes Engine GKE supports Tau VMs helping you optimize price performance for your containerized workloads You can add TD nodes to your GKE clusters by specifying the TD machine type in your GKE node pools This is useful if you re leveraging GKE s cluster autoscaler for example which resizes the number of nodes in a given node pool based on the demands of your workloads another example of horizontal scaling You specify a minimum and maximum size for the node pool and the rest is automatic TD VMs in this case would provide scale out performance and low latency during autoscaling events In addition cluster autoscaler considers the relative cost of the instance types in the various pools and attempts to expand the least expensive possible node pool Coupled with the TD VMs price performance ratio you can experience a lower total cost of ownership without sacrificing performance and scale   We worked with pre selected customers to test Tau VM performanceSnap Inc is continuing to improve their scale out compute infrastructure for key capabilities like AR Lenses Spotlight and Maps After testing the TD VMs with Google Kubernetes Engine they saw the potential for a double digit performance gain in the companies real world workloads Likewise Twitter shared their excitement about the price performance enhancements critical for their infrastructure used to serve the global public conversation  If you re interested in signing up to try out the Tau VMs slated for Q you can sign up here  Want to connect Find me
