Amazon EMR support prioritized and capacity-optimized-prioritized allocation strategies for EC2 instances

We are excited to announce that Amazon EMR on EC2 now supports two new allocation strategies for Instance Fleets - prioritized for On-Demand instances and capacity-optimized-prioritized for Spot instances. Allocation strategies let you determine how EMR selects from your list of specified instance types and Availability Zones to fulfill your desired capacity. These new strategies give you more control and flexibility when provisioning instances for your EMR workloads.? With today’s launch, you can use a prioritized list to determine the order in which EMR should attempt to provision your compute capacity. This new feature allows you to specify a priority for each instance type in your instance fleet configuration. For On-Demand instances, EMR will first attempt to fulfill capacity using the highest priority instance type. If EMR cannot fulfill the entire capacity using that instance type, it will then launch instances with the next highest priority, and so on. For Spot instances, EMR will optimize for capacity first, but will honor instance type priorities on a best-effort basis. This is great for workloads where the possibility of disruption must be minimized, but preferences for certain instance types matter.?

Introducing browser-based SSH/RDP support for IPv6-only instances bundles on Lightsail

Amazon Lightsail now extends support for browser-based SSH/RDP connections, also known as Lightsail Connect, to IPv6-only instances. Now, you can connect to your Linux or Windows IPv6-only instance directly from Lightsail Console in browser.? Previously, you would need to add a public IPv4 address to your IPv6-only instance to use Lightsail Connect. With the launch of IPv6 support, you can use Lightsail’s browser-based client that provides a quick and convenient way to connect to your instance and does not require any software installation.? You can use this feature on the Lightsail Console (accessed from AWS Console) in all AWS Regions supporting Lightsail.

AWS CodeBuild now supports Mac builds

Starting today, you can build applications on macOS with AWS CodeBuild. You can build artifacts on managed Apple M2 instances that run on macOS 14 Sonoma. AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces ready-to-deploy software packages.? Building, testing, signing, and distributing applications for Apple systems (iOS, iPadOS, watchOS, tvOS, and macOS) requires the use of Xcode which runs exclusively on macOS. You can provision a fleet of managed CodeBuild Mac instances which offer native integration with AWS, including Amazon VPC, AWS Secrets Manager, and IAM. You can use CodeBuild’s prepackaged build environment with common tools and frameworks, or you can bring your own Amazon EC2 AMI to provision the Mac instances in your fleet.?
