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…
New for Amazon CodeGuru Reviewer – Detector Library and Security Detectors for Log-Injection Flaws
Amazon CodeGuru Reviewer is a developer tool that detects security vulnerabilities in your code and provides intelligent recommendations to improve code quality. For example, CodeGuru Reviewer introduced Security Detectors for Java and Python code to identify security risks from the top ten Open Web Application Security Project (OWASP) categories and follow security best practices for AWS APIs and common crypto libraries. At re:Invent, CodeGuru Reviewer introduced a secrets detector to identify hardcoded secrets and suggest remediation steps to secure your secrets with AWS Secrets Manager. These capabilities help you find and remediate security issues before you deploy. Today, I am happy to share two new features of CodeGuru Reviewer: A new Detector Library describes in detail the detectors that CodeGuru Reviewer…
Amazon Elastic File System Update – Sub-Millisecond Read Latency
Amazon Elastic File System (Amazon EFS) was announced in early 2015 and became generally available in 2016. We launched EFS in order to make it easier for you to build applications that need shared access to file data. EFS is (and always has been) simple and serverless: you simply create a file system, attach it to any number of EC2 instances, Lambda functions, or containers, and go about your work. EFS is highly durable and scalable, and gives you a strong read-after-write consistency model. Since the 2016 launch we have added many new features and capabilities including encryption data at rest and in transit, an Infrequent Access storage class, and several other lower cost storage classes. We have also worked…
