Now Available: R5, R5d, and z1d Instances
|
Just last week I told you about our plans to launch EC2 Instances with Faster Processors and More Memory. Today I am happy to report that the R5, R5d, and z1d instances are available now and you can start using them today. Let’s take a look at each one!
R5 Instances
The memory-optimized R5 instances use custom Intel® Xeon® Platinum 8000 Series (Skylake-SP) processors running at up to 3.1 GHz, powered by sustained all-core Turbo Boost. They are perfect for distributed in-memory caches, in-memory analytics, and big data analytics, and are available in six sizes:
| Instance Name | vCPUs | Memory | EBS-Optimized Bandwidth | Network Bandwidth |
| r5.large | 2 | 16 GiB | Up to 3.5 Gbps | Up to 10 Gbps |
| r5.xlarge | 4 | 32 GiB | Up to 3.5 Gbps | Up to 10 Gbps |
| r5.2xlarge | 8 | 64 GiB | Up to 3.5 Gbps | Up to 10 Gbps |
| r5.4xlarge | 16 | 128 GiB | 3.5 Gbps | Up to 10 Gbps |
| r5.12xlarge | 48 | 384 GiB | 7.0 Gbps | 10 Gbps |
| r5.24xlarge | 96 | 768 GiB | 14.0 Gbps | 25 Gbps |
You can launch R5 instances today in the US East (N. Virginia), US East (Ohio), US West (Oregon), and Europe (Ireland) Regions. To learn more, read about R5 and R5d Instances.
R5d Instances
The R5d instances share their specs with the R5 instances, and also include up to to 3.6 TB of local NVMe storage. Here are the sizes:
| Instance Name | vCPUs | Memory | Local Storage | EBS-Optimized Bandwidth | Network Bandwidth |
| r5d.large | 2 | 16 GiB | 1 x 75 GB NVMe SSD | Up to 3.5 Gbps | Up to 10 Gbps |
| r5d.xlarge | 4 | 32 GiB | 1 x 150 GB NVMe SSD | Up to 3.5 Gbps | Up to 10 Gbps |
| r5d.2xlarge | 8 | 64 GiB | 1 x 300 GB NVMe SSD | Up to 3.5 Gbps | Up to 10 Gbps |
| r5d.4xlarge | 16 | 128 GiB | 2 x 300 GB NVMe SSD | 3.5 Gbps | Up to 10 Gbps |
| r5d.12xlarge | 48 | 384 GiB | 2 x 900 GB NVMe SSD | 7.0 Gbps | 10 Gbps |
| r5d.24xlarge | 96 | 768 GiB | 4 x 900 GB NVMe SSD | 14.0 Gbps | 25 Gbps |
The R5d instances are available in the US East (N. Virginia), US East (Ohio), and US West (Oregon) Regions. To learn more, read about R5 and R5d Instances.
z1d Instances
The high frequency z1d instances use custom Intel® Xeon® Scalable Processors running at up to 4.0 GHz, powered by sustained all-core Turbo Boost, perfect for Electronic Design Automation (EDA), financial simulation, relational database, and gaming workloads that can benefit from extremely high per-core performance. They are available in six sizes:
| Instance Name | vCPUs | Memory | Local Storage | EBS-Optimized Bandwidth | Network Bandwidth |
| z1d.large | 2 | 16 GiB | 1 x 75 GB NVMe SSD | Up to 2.333 Gbps | Up to 10 Gbps |
| z1d.xlarge | 4 | 32 GiB | 1 x 150 GB NVMe SSD | Up to 2.333 Gbps | Up to 10 Gbps |
| z1d.2xlarge | 8 | 64 GiB | 1 x 300 GB NVMe SSD | 2.333 Gbps | Up to 10 Gbps |
| z1d.3xlarge | 12 | 96 GiB | 1 x 450 GB NVMe SSD | 3.5 Gbps | Up to 10 Gbps |
| z1d.6xlarge | 24 | 192 GiB | 1 x 900 GB NVMe SSD | 7.0 Gbps | 10 Gbps |
| z1d.12xlarge | 48 | 384 GiB | 2 x 900 GB NVMe SSD | 14.0 Gbps | 25 Gbps |
The fast cores allow you to run your existing jobs to completion more quickly than ever before, giving you the ability to fine-tune your use of databases and EDA tools that are licensed on a per-core basis.
You can launch z1d instances today in the US East (N. Virginia), US West (Oregon), US West (N. California), Europe (Ireland), Asia Pacific (Tokyo), and Asia Pacific (Singapore) Regions. To learn more, read about z1d Instances.
In the Works
You will be able to create Amazon ElastiCache instances that make use of the R5 in the next two or three months.
The r5.metal, r5d.metal, and z1d.metal instances are on the near-term roadmap and I’ll let you know when they are available.
