This paper analyzes the increase in performance and capacity of the i3en instance type of VMware Cloud on AWS for Oracle Database. The i3en instance type offers more compute cores, more memory, and other performance enhancements that allow it to host larger and more powerful VMs. Testing found that Oracle databases running on i3en compared to the i3 instance provided about 18 percent more throughput per core and about double the throughput for similar-sized SDDCs. With this higher performance capability, VMware Cloud on AWS with i3en instance types can run larger Oracle databases than in the past.
