It is highly optimized for our peculiar needs, and supports lookups, queries, and joins across structured blobs of data. This was our first peak event that was supported at scale by the AWS Graviton2 instances, and is a strong indicator that the Arm architecture is well-suited to the data center.Īn internal service called Datapath is a key part of the Amazon site. Graviton2 Instances – Graviton2-powered EC2 instances supported 12 core retail services. Interestingly enough, due to increased efficiency (more on that in a moment), we actually used about 6,000 fewer physical servers than we did in Cyber Monday 2020. For Prime Day 2021, we increased our number of NIs by 12.5%. We use this unit to allow us to make meaningful comparisons across different types and sizes of EC2 instances. Here are a few examples:Īmazon EC2 – Our internal measure of compute power is an NI, or a normalized instance. A multitude of two-pizza teams worked together to make sure that every part of our infrastructure was scaled, tested, and ready to serve our customers.
This year I bought all sorts of useful goodies including a Toshiba 43 Inch Smart TV that I plan to use as a MagicMirror, some watering cans, and a Dremel Rotary Tool Kit for my workshop.Īs in years past, AWS played a critical role in making Prime Day a success. In what has now become an annual tradition (check out my 2016, 2017, 2019, and 2020 posts for a look back), I am happy to share some of the metrics from this year’s Prime Day and to tell you how AWS helped to make it happen.
