AWS Summit season is in full swing around the world, with last week’s events in Bengaluru, Berlin, and Seoul, where my blog colleague Channy delivered one of the keynotes. Last week’s launches Here are some launches that got my attention: Amazon S3 will no longer charge for several HTTP error codes – A customer reported how he was charged for Amazon S3 API requests he didn’t initiate and which resulted in AccessDenied errors. The Amazon Simple Storage Service (Amazon S3) service team updated the service to not charge such API requests anymore. As always when talking about pricing, the exact wording is important, so please read the What’s New post for the details. Introducing Amazon EC2 C7i-flex instances – These instances delivers up to 19 percent better price performance compared to C6i instances. Using C7i-flex instances is 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 percent lower prices compared to C7i. Application Load Balancer launches IPv6 only support for internet clients – Application Load Balancer now allows customers to provision load balancers without IPv4s for clients that can connect using just IPv6s. To connect, clients can resolve AAAA DNS records that are assigned to Application Load Balancer. The Application Load Balancer is still dual stack for communication between the load balancer and targets. With this new capability, you have the flexibility to use both IPv4s or IPv6s for your application targets while avoiding IPv4 charges for clients that don’t require it. Amazon VPC Lattice now supports TLS Passthrough – We announced the general availability of TLS passthrough for Amazon VPC Lattice, which allows customers to enable end-to-end authentication and encryption using their existing TLS or mTLS implementations. Prior to this launch, VPC Lattice supported HTTP and HTTPS listener protocols only, which terminates TLS and performs request-level routing and load balancing based on information in HTTP headers. Amazon DocumentDB zero-ETL integration with Amazon OpenSearch Service – This new integration provides you with advanced search capabilities, such as fuzzy search, cross-collection search and multilingual search, on your Amazon DocumentDB (with MongoDB compatibility) documents using the OpenSearch API. With a few clicks in the AWS Management Console, you can now synchronize your data from Amazon DocumentDB to Amazon OpenSearch Service, eliminating the need to write any custom code to extract, transform, and load the data. Amazon EventBridge now supports customer managed keys (CMK) for event buses – This capability allows you to encrypt your events using your own keys instead of an AWS owned key (which is used by default). With support for CMK, you now have more fine-grained security control over your events, satisfying your company’s security requirements and governance policies. For a full list of AWS announcements, be sure to keep an eye on the What's New at AWS page. Other AWS news Here are some additional news items, open source projects, and Twitch shows that you might find interesting: The Four Pillars of Managing Email Reputation – Dustin Taylor is the manager of anti-abuse and email deliverability for Amazon Simple Email Service (SES). He wrote a remarkable post exploring Amazon SES approach to managing domain and IP reputation. Maintaining a high reputation ensures optimal recipient inboxing. His post outlines how Amazon SES protects its network reputation to help you deliver high-quality email consistently. A worthy read, even if you’re not sending email at scale. I learned a lot. Build On Generative AI – Season 3 of your favorite weekly Twitch show about all things generative artificial intelligence (AI) is in full swing! Streaming every Monday, 9:00 AM US PT, my colleagues Tiffany and Darko discuss different aspects of generative AI and invite guest speakers to demo their work. AWS open source news and updates – My colleague Ricardo writes this weekly open source newsletter, in which he highlights new open source projects, tools, and demos from the AWS Community.

Amazon CloudWatch Logs now offers customer to use Internet Protocol version 6 (IPv6) addresses for their new and existing domains. Customers moving to IPV6 can simplify their network stack by running their CloudWatch log groups on a dual-stack network that supports both IPv4 and IPv6. View the full article

Amazon Elastic Kubernetes Service (EKS) customers can now leverage EC2 security groups to secure applications in clusters using Internet Protocol version 6(IPv6) address space. View the full article

AWS Lambda now allows Lambda functions to access resources in dual-stack VPC (outbound connections) over IPv6, at no additional cost. With this launch, and Lambda’s support for public IPv6 endpoints (inbound connections) in 2021, Lambda enables you to scale your application without being constrained by the limited number of IPv4 addresses in your VPC, and to reduce costs by minimizing the need for translation mechanisms.

AWS Global Accelerator now offers dual-stack accelerators that enable you to route IPv6 traffic to Regional Application Load Balancer endpoints. Starting today, you can get the availability, security and performance benefits of AWS Global Accelerator for both IPv4 and IPv6 traffic while routing traffic towards Application Load Balancer endpoints.

In this week’s The Long View: IPv6 gets stabbed in the back, Fintech firms’ valuations are falling, and the latest browser war seems to be over—Firefox lost. View the full article

AWS App Mesh now supports IPv6 allowing customers to support workloads running in IPv6 networks and to invoke App Mesh APIs over IPv6. This helps customers to meet IPv6 compliance requirements, and removes the need for expensive networking equipment to handle address translation between IPv4 and IPv6. AWS App Mesh is a service mesh that provides application-level networking to make it easier for your services to communicate with each other across multiple types of compute infrastructure. AWS App Mesh standardizes how your services communicate, giving you end-to-end visibility and options to tune for high-availability of your applications. View the full article

Amazon Web Services (AWS) announces the launch of multiple IPv6 classless inter-domain routing (CIDR) blocks in a Virtual Private Cloud (VPC), enabling customer to attach up to 5 prefixes to their VPCs. Before today, customers could add up to 5 IPv4 CIDR blocks and 1 IPv6 block. With this new feature, customers can now use multiple blocks to build logical separation within their VPCs with independent CIDR blocks. CIDR blocks can be associated from the Amazon provided pool and/or a pool of bring-your-own IPv6 addresses. View the full article

You can now connect over IPv6 to your services hosted in AWS using AWS PrivateLink. AWS PrivateLink is a highly available, scalable technology that enables you to privately connect your VPC to supported AWS services, services hosted by other AWS accounts (VPC Endpoint Services), third-party SaaS services and supported AWS Marketplace partner services.

Amazon Elastic Container Service (ECS) now supports native Internet Protocol version 6 (IPv6) for Amazon ECS tasks using task networking (awsvpc networking mode). Previously, IPv6 was only supported in host networking mode. With this capability, tasks using awsvpc networking mode can communicate with other endpoints in Amazon Virtual Private Cloud (Amazon VPC) and internet in dual-stack mode via either IPv4 or IPv6. This will allow customers to communicate with on-premises resources that support only IPv6 addresses and meet IPv6 compliance requirements. View the full article
