While datacenter based IT costs are largely fixed, in a three year depreciation schedule, cloud costs are inherently variable, and can be sized to fit the need. When times get tough, a focus on cost optimization can also greatly reduce cloud costs, and the results take effect in next month’s bill.

Soon after the launch of Amazon Relation Dabase Service (RDS) AWS customers were giving us feedback that they would love to migrate to RDS but what they would love even more was if we could also unshackle them from the high-cost, punitive licensing schemes that came with the proprietary databases.

Hardware virtualization for cloud computing has come a long way, improving performance using technologies such as VT-x, SR-IOV, VT-d, NVMe, and APICv. At Netflix, we've been using these technologies as they've been made available for instance types in the AWS EC2 cloud. AWS called this [enhanced networking]. Impressive!
