AWS Elastic Disaster Recovery now preserves UEFI boot mode for Linux servers

AWS Elastic Disaster Recovery (AWS DRS) now preserves UEFI boot mode when recovering Linux source servers that boot with UEFI firmware. Previously, DRS launched these Linux servers in legacy BIOS mode, which could require extra configuration after recovery. Now your recovered Linux instances launch with the same UEFI boot mode as your source servers. This means your recovery instances more closely match your source environment, so applications that depend on UEFI boot behavior come back exactly as you expect — with no additional post-recovery steps. Boot mode preservation is automatic, with nothing to configure.
This capability is available in all AWS Regions where AWS DRS is offered, at no additional cost. To learn more, visit the AWS Elastic Disaster Recovery User Guide.

Amazon OpenSearch Serverless now supports up to 10,000 collections per collection group

The next generation of Amazon OpenSearch Serverless now supports up to 10,000 collections within a single collection group, increased from the previous limit of 1,500. Collection groups organize multiple collections and enable them to share OpenSearch Compute Units (OCUs), even when the collections are encrypted with different AWS KMS keys. With this higher limit, you can consolidate significantly more collections into a single collection group and manage them under a shared set of capacity limits.
Customers use collection groups to reduce costs by sharing compute across many collections rather than provisioning separate OCUs for each KMS key, while still maintaining collection-level security and access controls. As customer workloads have grown, particularly for multi-tenant applications that provision a collection per tenant, the previous limit of 1,500 collections per group constrained how many tenants could benefit from a shared compute pool. Raising the limit to 10,000 collections on the next generation of Amazon OpenSearch Serverless lets you scale these workloads further, improve compute utilization, and lower per-collection cost, without creating and operating additional collection groups. The higher limit applies automatically to new and existing nextgen collection groups.
The increased limit is available on the next generation of Amazon OpenSearch Serverless in all AWS Regions where it is available. To learn more, see Amazon OpenSearch Serverless technical documentation and quotas.

Amazon EC2 introduces application status checks

Amazon EC2 introduces application status checks, a new status check that helps customers detect and respond to application-level issues on their EC2 instances. With application status checks, EC2 monitors applications to detect issues such as a web server that has stopped accepting requests, a Docker daemon that is not running, an incorrect networking configuration, or a network interface that is no longer passing traffic.
Customers rely on EC2 status checks today to receive alerts when an instance or the underlying system is unreachable. However, to monitor application issues, customers had to build and maintain their own monitoring solution. Now, with application status checks customers can monitor the status of their applications running on EC2 instances alongside existing EC2 instance and system status checks. Customers create a check by specifying the protocol, port, and path to monitor, along with the response codes that indicate a healthy application. After customers associate the check with their instances by instance ID or tag, Amazon EC2 sends HTTP or HTTPS requests to that port and path and reports on the application’s status every 60 seconds. Auto Scaling groups act on application status, initiating recovery by replacing instances when their applications report unhealthy.
Application status checks are available in all commercial AWS Regions and AWS GovCloud (US) Regions.
To get started with application status checks and review pricing, see the Amazon EC2 User Guide.
