Amazon SQS expands IPv6 support to VPC endpoints in AWS commercial Regions

Amazon Simple Queue Service (Amazon SQS) now allows customers to make API requests over Internet Protocol version 6 (IPv6) through AWS PrivateLink with Virtual Private Cloud (VPC) endpoints. This launch extends IPv6 compatibility, previously available only for public endpoints, to VPC endpoints across all AWS commercial Regions.\n Amazon SQS is a fully managed message queuing service that enables decoupling and scaling of distributed systems, microservices, and serverless applications. With this update, customers can now use VPC Endpoints to privately connect their VPCs to Amazon SQS using IPv6. With simultaneous support for both IPv4 and IPv6 clients on SQS VPC endpoints, customers can gradually transition from IPv4 to IPv6-based systems and applications without needing to switch all systems at once. IPv6 support for VPC endpoints is now available in all AWS commercial Regions, including AWS China Regions operated by Sinnet and NWCD. For more information on using Amazon SQS with interface VPC endpoints, please refer to our Developer Guide. To learn more about AWS PrivateLink, see accessing AWS services through AWS PrivateLink.

Amazon EC2 High Memory U7i instances now support higher Amazon EBS-optimized instance performance

Today, we are announcing enhanced Amazon Elastic Block Store (EBS) performance for Amazon EC2 High Memory U7i instances. This improvement delivers increased storage performance for memory-intensive workloads such as SAP HANA, Oracle, and Microsoft SQL Server databases.\n With the latest enhancements to the AWS Nitro System, U7i instances now support up to 560,000 IOPS and 100 Gbps of EBS-optimized bandwidth. We recommend using io2 Block Express volumes for maximum IOPS performance. This increased EBS performance enables faster database operations and reduced restart times for large in-memory databases. All existing and new U7i instances launched starting today will benefit from this performance increase at no additional cost. For running instances, you can simply stop and start your instances to enable this performance increase. The higher EBS performance is available in all AWS Regions where U7i instances are generally available today. Please visit the EBS-optimized instance page for more details.

AWS Private CA now supports issuing up to 100 million certificates per CA

AWS Private Certificate Authority (AWS Private CA) now enables you to issue up to 100 million certificates per certificate authority (CA), an increase from the previous default limit of 1 million certificates. This limit increase allows you to optimize your CA operations by managing fewer CAs while maintaining the security and flexibility of your public key infrastructure (PKI).\n The new 100 million certificates per CA limit is available by default for CAs configured without revocation or with revocation configuration set to partitioned Certificate Revocation List (CRL) and/or Online Certificate Status Protocol (OCSP). CAs configured with complete CRL will continue to have a maximum limit of 1 million certificates per CA. If you are currently using complete CRL and need to issue more certificates, you can switch to partitioned CRL to automatically increase the certificates per CA limit to 100 million certificates. AWS Private CA is a managed service that lets you create private certificate authorities (CAs) to issue digital certificates for authenticating internal users, servers, applications, and devices within your organization, while securing the CA’s private keys using Federal Information Processing Standard (FIPS) 140-3 Level 3 hardware security modules (HSMs). AWS Private CA offers connectors so you can use AWS Private CA with Kubernetes, Active Directory, and mobile device management (MDM) software. AWS Private CA is available in all commercial AWS Regions, the AWS GovCloud (US) Regions, and the China Regions. To learn more about AWS Private CA certificate limits, see AWS Private CA Service Quotas.

AWS Firewall Manager adds support for AWS Private Link

AWS Firewall Manager announces security policy support for AWS Private Link. Customers have come to rely on AWS Private Link for secure communications, and AWS Firewall Manager to configure security services for their asset’s protection. Customers can now access and manage their Firewall Manager privately, without going through the public internet. AWS PrivateLink provides private connectivity between VPCs, AWS services, and on-premises applications, securely over the Amazon network. When AWS PrivateLink is used with AWS Firewall Manager, all management and control traffic between clients and Network Firewall flows over a private network.\n To learn more about how AWS Firewall Manager works with AWS Private Link see the AWS Firewall Manager documentation for more details and the AWS Region Table for the list of regions where AWS Firewall Manager is currently available. To learn more about AWS Firewall Manager, its features, and its pricing, visit the AWS Firewall Manager website.

Amazon RDS Custom for SQL Server is now available in the AWS Africa (Cape Town) Region

Amazon SNS expands IPv6 support to VPC endpoints in AWS commercial Regions

Amazon Simple Notification Service (Amazon SNS) now allows customers to make API requests over Internet Protocol version 6 (IPv6) through AWS PrivateLink with Virtual Private Cloud (VPC) endpoints. This launch extends IPv6 compatibility, previously available only for public endpoints, to VPC endpoints across all AWS commercial Regions.\n Amazon SNS is a fully managed messaging service that enables publish/subscribe messaging between distributed systems, microservices, and event-driven serverless applications. With this update, customers can now use VPC Endpoints to privately connect their VPCs to Amazon SNS using IPv6. With simultaneous support for both IPv4 and IPv6 clients on SNS VPC endpoints, customers can gradually transition from IPv4 to IPv6-based systems and applications without needing to switch all systems at once. IPv6 support for VPC endpoints is now available in all AWS commercial Regions, including AWS China Regions operated by Sinnet and NWCD. For more information on using Amazon SNS with interface VPC endpoints, please refer to our Developer Guide. To learn more about AWS PrivateLink, see accessing AWS services through AWS PrivateLink.

Amazon CloudWatch SDK supports optimized JSON, CBOR protocols (in preview)

Amazon CloudWatch announces support for both the JSON and Concise Binary Object Representation (CBOR) protocols in the CloudWatch SDK, enabling lower latency and improved performance for CloudWatch customers. The SDK will automatically use JSON or CBOR as its new default communication protocol, offering customers a lower end-to-end processing latency as well as reduced payload sizes, application client side CPU, and memory usage.\n Customers use the CloudWatch SDK either directly or through Infrastructure as Code solutions to manage their monitoring resources. Reducing control plane operations latency and payload size helps customer optimize their operational maintenance and resources usage and costs. JSON and the CBOR data formats are standards designed to enable better performance over the traditional AWS Query protocol. The CloudWatch SDK for JSON and CBOR protocols support (in preview) is available in all AWS Regions where Amazon CloudWatch is available and for all generally available AWS SDK language variants. To leverage the performance improvements in non-production accounts, customers can install the preview SDK from the links included in CloudWatch documentation. To learn more about the AWS SDK, see Amazon Developer tools.
