Earlier this year, Amazon's AWS group said that it was working on bringing instance types with between 4 to 16TB of memory to its users. It's now starting to fulfill this promise as the company today launched its largest EC2 machine (in terms of memory size) yet: the x1e.32xlarge instance with a whopping 4.19TB of RAM. Previously, EC2's largest instance only featured just over 2TB of memory.
These machines with feature quad-socket Intel Xeon processors running at 2.3 GHz, up to 25 Gbps of network bandwidth and two 1,920GB SSDs. There are obviously only a few applications that need this kind of memory. It's no surprise then that these instances are certified to run SAP's Hana in-memory database and its various tools and that SAP will offer direct support for running these applications on these instances.
These new instances are now available in four AWS regions: US East (Northern Virginia), US West (Oregon), EU (Ireland) and Asia Pacific (Tokyo). Running these instances doesn't come cheap, of course. On-demand pricing in the US East region is $26.688 per hour and in Tokyo its $38.688, for example. That makes them AWS's most expensive machines yet.
