AWS Announces Availability of z1d & R5 EC2 Instances

Last week Amazon Web Services (AWS) announced new instances on its Elastic Compute Cloud (EC2). This week, AWS is announcing that the new high frequency instance, z1d, and the two new memory optimized instances, R5 and R5d, are now generally available. These new instances are designed for users that need massive performance and better price-per-GB in memory intensive applications. 

As more companies adopt, move to, or are born in the cloud, they will begin to need more performance. In some cases they may only need the performance for a short period of time or for only specific workloads. The new instances will allow for performance that is not traditionally associated with the cloud.

As we previously stated, the with the z1d instance, AWS leverages custom Intel Xeon Scalable Processors that run up to 4.0 GHz and are powered by sustained all-core Turbo Boost. z1d is for applications that need very high per-core performance. z1d will come in six sizes ranging from 2 vCPUs with 16GiB of memory and 75GB of NVMe storage all the way up to 48 vCPUs with 384GiB of memory and 1.8TB of NVMe storage. Bandwidth will range from 10Gb/s to 25Gb/s.

The R5 and R5d are memory-optimized instances. These instances are offered with up to 3.1GHz powered by sustained all-core Turbo Boost and the R5d that is equipped with local NVMe storage (up to 3.6TB). These instances are designed for high-performance databases, distributed in-memory caches, in-memory analytics, and big data analytics. The instances will leverage custom Intel Xeon Platinum 8000 Series CPUs. They R5 instances also come in six sizes, this time ranging from 2 vCPUs to 96 vCPUs, network bandwidth runs from 10Gb/s to 25Gb/s.

The new instances are based on AWS Nitro System, a collection of hardware and software components that are AWS-built for performance, HA, security and bare metal capabilities. 


The z1d, R5, and R5d instances are available now and can be purchased as On-demand, Reserved, or Spot instances.
