Amazon Elastic Container Service (ECS) now supports Docker container health checks. This gives you more control over monitoring the health of your tasks and improves the ability of the ECS service scheduler to ensure your services are healthy.

The Amazon Elastic Container Service (Amazon ECS) service scheduler now includes logic that throttles how often tasks are restarted if they repeatedly fail to launch. Previously, if tasks had issues in the container image, task definition, network configuration, they could fail to become healthy when started by the Amazon ECS service scheduler. Continuous restart attempts by the service scheduler

AWS X-Ray now supports the ability to zoom and pan your service map. This allows you to focus on a particular service of interest and visualize service maps with large number of service nodes on a single screen.

Spread placement groups help reduce the likelihood of failures within clusters or groups of instances. Amazon EC2 has had cluster placement groups, which enable applications to get the low-latency network performance necessary for tightly-coupled node-to-node communication typical of many HPC applications. Now with spread placement groups, member instances will be placed on distinct hardware, redu

AWS News Blog T2 Unlimited – Going Beyond the Burst with High Performance I first wrote about the T2 instances in the summer of 2014, and talked about how many workloads have a modest demand for continuous compute power and an occasional need for a lot more. This model resonated with our customers; the T2 instances are very popular and are now used to host microservices, low-latency interactive ap

AWS News Blog Amazon DynamoDB Update – Global Tables and On-Demand Backup AWS customers in a wide variety of industries use Amazon DynamoDB to store mission-critical data.

AWS News Blog Amazon Neptune – A Fully Managed Graph Database Service Of all the data structures and algorithms we use to enable our modern lives, graphs are changing the world everyday. Businesses continuously create and ingest rich data with complex relationships. Yet developers are still forced to model these complex relationships in traditional databases. This leads to frustratingly complex qu

AWS News Blog S3 Select and Glacier Select – Retrieving Subsets of Objects Amazon Simple Storage Service (Amazon S3) stores data for millions of applications used by market leaders in every industry. Many of these customers also use Amazon Glacier for secure, durable, and extremely low-cost archival storage. With S3, I can store as many objects as I want and individual objects can be as large as 5

Amazon Elastic Container Service for Kubernetes (Amazon EKS) is a managed service that makes it easy for you to run Kubernetes on AWS without needing to install, operate, and maintain your own Kubernetes clusters. Previously, you had to manage the scaling and availability of your Kubernetes masters and persistence layer by choosing appropriate instance types, running them across multiple Availabil

AWS Open Source Blog Better Random Number Generation for OpenSSL, libc, and Linux Mainline 中文版 In 2015, AWS introduced s2n, a new open source implementation of the TLS/SSL protocols that protect the privacy and integrity of data moving over a network. s2n was designed to be secure, simple, small, and fast. The project is thriving, and we use it extensively. In February, our CISO Stephen Schmidt sh

We are pleased to announce the launch of a new Network Load Balancer for the Elastic Load Balancing service designed to handle millions of requests per second while maintaining ultra-low latencies. This new load balancer is optimized to handle volatile traffic patterns while using a single static IP address per Availability Zone. Network Load Balancer operates at the connection level (Layer 4), ro

The AWS X-Ray SDK enables Python developers to record and emit information from within their applications to the AWS X-Ray service. You can get started in minutes using pip or by downloading a zip file containing the SDK. Currently supported web frameworks and libraries include: boto3 botocore requests django >=1.10 sqlite3 mysql-connector To learn more about Python SDK, please visit API documenta

AWS News Blog Latency Distribution Graph in AWS X-Ray We’re continuing to iterate on the AWS X-Ray service based on customer feedback and today we’re excited to release a set of tools to help you quickly dive deep on latencies in your applications. Visual Node and Edge latency distribution graphs are shown in a handy new “Service Details” side bar in your X-Ray Service Map. The X-Ray service graph

For illustrative purposes, we have randomly generated a set of 300,000 such temperature reports. Each report has been attributed to a single fictional weather organization called Under the Weather (UTW), which has a source ID of 1. The data spans three months and covers the continental United States. We will use this dataset to demonstrate the performance of various queries and indexes. Traditiona

AWS News Blog New – Host-Based Routing Support for AWS Application Load Balancers Last year I told you about the new AWS Application Load Balancer (an important part of Elastic Load Balancing) and showed you how to set it up to route incoming HTTP and HTTPS traffic based on the path element of the URL in the request. This path-based routing allows you to route requests to, for example, /api to one

We’d like to give you some additional information about the service disruption that occurred in the Northern Virginia (US-EAST-1) Region on the morning of February 28th, 2017.

先入れ先出し (FIFO) キューを使用して厳密なシーケンスで 1 回だけメッセージを処理する必要があるアプリケーションで、Amazon Simple Queue Service (SQS) を使用できるようになりました。FIFO キューは、メッセージが送受信される順序を厳密に保持し、各メッセージが 1 回だけ処理されるように設計されています。 Amazon SQS は、アプリケーションコンポーネントの間で転送されるメッセージを保存するための、信頼性が高く、非常にスケーラブルなマネージド型のメッセージキューサービスです。FIFO キューは、高スループット、ベストエフォート型の順序、および少なくとも 1 回の配信を提供する、既存の Amazon SQS 標準キューを補完します。FIFO キューは基本的に標準キーと同じ機能を備えていますが、順序と 1 回だけの処理のサポートという追加の利点があ
