Effective mid-2024, newly released Amazon EC2 instance types will use only version 2 of the EC2 Instance Metadata Service (IMDSv2). We are also taking a series of steps to make IMDSv2 the default choice for AWS Management Console Quick Starts and other launch pathways. Background This service is accessible from within an EC2 instance at a fixed IP address (169.254.169.254 via IPv4 or fd00:ec2::254 via IPv6 on Nitro instances). It gives you (or the code running on the instance) access to a wealth of static and dynamic data including the ID of the AMI that was used to launch the instance, block device mappings, temporary IAM credentials for roles that are attached to the instance, network interface information, user data,…

The AWS European Sovereign Cloud will allow government agencies, regulated industries, and the independent software vendors (ISVs) that support them to store sensitive data and run critical workloads on AWS infrastructure that is operated and supported by AWS employees located in and residents of the European Union (EU). The first Region will be located in Germany. Background Late last year we announced the AWS Digital Sovereignty Pledge and made a commitment to offer you (and all AWS customers) the most advanced set of sovereignty controls and features available in the cloud. Since that announcement we have taken several important steps forward in fulfillment of that pledge: May 2023 – We announced that AWS Nitro System had been validated by an…

With just 41 days until AWS re:Invent 2023 opens, I’m doing my best to stay heads-down and focused on working with the entire AWS News Blog team to create plenty of awesome new posts for your reading pleasure! I’ll take a short break this morning to share some of the most exciting launches and other news from last week. Here we go! Last Week’s Launches Here are some of the launches that captured my attention: Amazon EBS – The new Attached EBS Status Check CloudWatch metric lets you monitor the status of all of the Amazon Elastic Block Store (Amazon EBS) volumes attached to a particular Amazon Elastic Compute Cloud (Amazon EC2) instance, verifying that the volumes are reachable and…

Amazon Elastic Block Store (Amazon EBS) io2 and io2 Block Express volumes now support storage fencing using NVMe reservations. As I learned while writing this post, storage fencing is used to regulate access to storage for a compute or database cluster, ensuring that just one host in the cluster has permission to write to the volume at any given time. For example, you can set up SQL Server Failover Cluster Instances (FCI) and get higher application availability within a single Availability Zone without the need for database replication. As a quick refresher, io2 Block Express volumes are designed to meet the needs of the most demanding I/O-intensive applications running on Nitro-based Amazon Elastic Compute Cloud (Amazon EC2) instances. Volumes can…
