Introduction:
AWS continues to innovate, and this month has been no exception. Here are some of the most significant AWS updates from the current month.
Updates
Announcing New EC2 R8a Memory-Optimized Instances
[Published On: November 5, 2025] AWS is announcing the general availability of new memory-optimized Amazon EC2 R8a instances. R8a instances, feature 5th Gen AMD EPYC processors (formerly code named Turin) with a maximum frequency of 4.5 GHz, deliver up to 30% higher performance, and up to 19% better price-performance compared to R7a instances. R8a instances deliver 45% more memory bandwidth compared to R7a instances, making these instances ideal for latency sensitive workloads. Compared to Amazon EC2 R7a instances, R8a instances provide up to 60% faster performance for GroovyJVM, allowing higher request throughput and better response times for business-critical applications. Built on the AWS Nitro System using sixth generation Nitro Cards, R8a instances are ideal for high performance, memory-intensive workloads, such as SQL and NoSQL databases, distributed web scale in-memory caches, in-memory databases, real-time big data analytics, and Electronic Design Automation (EDA) applications. R8a instances offer 12 sizes including 2 bare metal sizes. Amazon EC2 R8a instances are SAP-certified, and providing 38% more SAPS compared to R7a instances. R8a instances are available in the following AWS Regions: US East (N. Virginia), US East (Ohio), and US West (Oregon) regions. To get started, sign in to the AWS Management Console. Customers can purchase these instances via Savings Plans, On-Demand instances, and Spot instances. For more information visit the Amazon EC2 R8a instance page.

Amazon Kinesis Data Streams launches On-demand Advantage mode
[Published On: November 4, 2025] Amazon Kinesis Data Streams launches On-demand Advantage, so customers can warm on-demand streams to handle instant throughput increases up to 10GB or 10 million events per second, eliminating the need to over-provision or build custom scaling solutions. Amazon Kinesis Data Streams is a serverless streaming data service that makes it easy to capture, process, and store data streams at any scale. On-demand streams automatically scale capacity based on data usage, and now you can warm write capacity ad hoc. On-demand Advantage also provides a simpler pricing structure that removes the fixed, per-stream charge, so customers only pay for data usage at better rates. On-demand Advantage offers data usage with 60% lower pricing compared to On-demand Standard, with data ingest at $0.032/GB and data retrieval at $0.016/GB in the US East (N. Virginia) region. The price of Enhanced fan-out data retrieval is the same as shared-throughput retrievals, making higher fan-out use cases more cost effective. The mode also decreases the price of extended retention by 77% from $0.10/GB-month to $0.023/GB-month. Once you enable On-demand Advantage mode, the account will be billed for a minimum of 25MB/s of data ingest and 25MB/s of data retrieval at the lower rates across all on-demand streams. The new pricing means On-demand Advantage is the most cost effective way to stream with Kinesis Data Streams when you ingest at least 10MB/s in aggregate, fan out to more than two consumer applications, or have hundreds of streams in a region. You can check directly in the Kinesis console and the pricing page if On-demand Advantage is a good fit for your account. On-demand Advantage is available in all AWS regions where Kinesis Data Streams is available, including AWS GovCloud (US) and China regions. To learn more, see the launch blog and the Kinesis Data Streams User Guide.

Amazon EC2 C7i-flex instances are now available in the Middle East (UAE) Region
[Published On: November 10, 2025] Starting today, Amazon Elastic Compute Cloud (Amazon EC2) C7i-flex instances that deliver up to 19% better price performance compared to C6i instances, are available in the Middle East (UAE) Region. C7i-flex instances provide the easiest way for you to get price performance benefits for a majority of compute intensive workloads. The new instances are powered by the 4th generation Intel Xeon Scalable custom processors (Sapphire Rapids) that are available only on AWS, and offer 5% lower prices compared to C7i. C7i-flex instances offer the most common sizes, from large to 16xlarge, and are a great first choice for applications that don’t fully utilize all compute resources. With C7i-flex instances, you can seamlessly run web and application servers, databases, caches, Apache Kafka, and Elasticsearch, and more. For compute-intensive workloads that need larger instance sizes (up to 192 vCPUs and 384 GiB memory) or continuous high CPU usage, you can leverage C7i instances. To learn more, visit Amazon EC2 C7i-flex instances. To get started, see the AWS Management Console.

AWS adds IPv6 support for Amazon S3 Gateway and Interface VPC endpoints
[Published On: November 10, 2025] Amazon Web Services (AWS) now supports Internet Protocol version 6 (IPv6) addresses for AWS PrivateLink Gateway and Interface Virtual Private Cloud (VPC) endpoints for Amazon S3. The continued growth of the internet is exhausting available Internet Protocol version 4 (IPv4) addresses. IPv6 increases the number of available addresses by several orders of magnitude, and customers no longer need to manage overlapping address spaces in their VPCs. To get started with IPv6 connectivity on a new or existing S3 gateway or interface endpoint, configure IP address type for the endpoint to IPv6 or Dualstack. When enabled, Amazon S3 automatically updates the routing tables with IPv6 addresses for gateway endpoints and sets up an Elastic network interface (ENI) with IPv6 addresses for interface endpoints. IPv6 support for VPC endpoints for Amazon S3 is now available in all AWS Commercial Regions and the AWS GovCloud (US) Regions, at no additional cost. You can set up IPv6 for new and existing VPC endpoints using the AWS Management Console, AWS CLI, AWS SDK, or AWS CloudFormation. To learn more, please refer to the service documentation.
