Amazon EC2 Update – X1e Instances in Five More Sizes and a Stronger SLA

Earlier this year we launched the x1e.32xlarge instances in four AWS Regions with 4 TB of memory. Today, two months after that launch, customers are using these instances to run high-performance relational and NoSQL databases, in-memory databases, and other enterprise applications that are able to take advantage of large amounts of memory.

Five More Sizes of X1e
I am happy to announce that we are extending the memory-optimized X1e family with five additional instance sizes. Here’s the lineup:

Model vCPUs Memory (GiB) SSD Storage (GB) Networking Performance
x1e.xlarge 4 122 120 Up to 10 Gbps
x1e.2xlarge 8 244 240 Up to 10 Gbps
x1e.4xlarge 16 488 480 Up to 10 Gbps
x1e.8xlarge 32 976 960 Up to 10 Gbps
x1e.16xlarge 64 1,952 1,920 10 Gbps
x1e.32xlarge 128 3,904 3,840 25 Gbps

The instances are powered by quad socket Intel® Xeon® E7 8880 processors running at 2.3 GHz, with large L3 caches and plenty of memory bandwidth. ENA networking and EBS optimization are standard, with up to 14 Gbps of dedicated throughput (depending on instance size) to EBS.

As part of today’s launch we are also making all sizes of X1e available in the Asia Pacific (Sydney) Region. This means that you can now launch them in On-Demand and Reserved Instance form in the US East (N. Virginia), US West (Oregon), EU (Ireland), Asia Pacific (Tokyo), and Asia Pacific (Sydney) Regions.

Stronger EC2 SLA
I also have another piece of good news!

Effective immediately, we are increasing the EC2 Service Level Agreement (SLA) for both EC2 and EBS to 99.99%, for all regions and for all AWS customers. This change was made possible by our continuous investment in infrastructure and quality of service, along with our focus on operational excellence.
