Carbon is the fourth-most abundant element in the universe, and is also a primary component of all known life on Earth. When combined with oxygen it creates carbon dioxide (CO2). Many industrial activities, including the burning of fossil fuels such as coal and oil, release CO2 into the atmosphere and cause climate change. As part of Amazon’s efforts to increase sustainability and reduce carbon emissions, we co-founded The Climate Pledge in 2019. Along with the 216 other signatories to the Pledge, we are committed to reaching net-zero carbon by 2040, 10 years ahead of the Paris Agreement. We are driving carbon out of our business in a multitude of ways, as detailed on our Carbon Footprint page. When I share…
Let Your IPv6-only Workloads Connect to IPv4 Services
Today we are announcing two new capabilities for Amazon Virtual Private Cloud (VPC) NAT gateway and Amazon Route 53, allowing your IPv6-only workloads to transparently communicate with IPV4-only services. Curious? Read on; I have details for you. Some of you are running very large workloads involving tens of thousands of virtual machines, containers, or micro-services. To do so, you configured these workloads to work in the IPv6 address space. This avoids the problem of running out of available IPv4 addresses (a single VPC has a maximum theoretical size of 65,536 IPv4 addresses, compared to /56 ranges for IPv6, allowing for a maximum theoretical size of 2^73 -1 IPv6 addresses), and it saves you from additional headaches caused by managing complex…
New – Additional Checksum Algorithms for Amazon S3
Amazon Simple Storage Service (Amazon S3) is designed to provide 99.999999999% (11 9s) of durability for your objects and for the metadata associated with your objects. You can rest assured that S3 stores exactly what you PUT, and returns exactly what is stored when you GET. In order to make sure that the object is transmitted back-and-forth properly, S3 uses checksums, basically a kind of digital fingerprint. S3’s PutObject function already allows you to pass the MD5 checksum of the object, and only accepts the operation if the value that you supply matches the one computed by S3. While this allows S3 to detect data transmission errors, it does mean that you need to compute the checksum before you call…
Happy 10th Birthday, DynamoDB! 🎉🎂🎁
On January 18th 2012, Jeff and Werner announced the general availability of Amazon DynamoDB, a fully managed flexible NoSQL database service for single-digit millisecond performance at any scale. During the last 10 years, hundreds of thousands of customers have adopted DynamoDB. It regularly reaches new peaks of performance and scalability. For example, during the last Prime Day sales in June 2021, it handled trillions of requests over 66 hours while maintaining single-digit millisecond performance and peaked at 89.2 million requests per second. Disney+ uses DynamoDB to ingest content, metadata, and billions of viewers actions each day. Even during unprecedented demands caused by the pandemic, DynamoDB was able to help customers as many across the world had to change their way…
