Amazon EC2 R8i and R8i-flex instances are now available in Europe (London)
Starting today, Amazon Elastic Compute Cloud (Amazon EC2) R8i and R8i-flex instances are available in the Europe (London) region. These instances are powered by custom Intel Xeon 6 processors, available only on AWS, delivering the highest performance and fastest memory bandwidth among comparable Intel processors in the cloud. The R8i and R8i-flex instances offer up to 15% better price-performance, and 2.5x more memory bandwidth compared to previous generation Intel-based instances. They deliver 20% better performance than R7i instances, with even higher gains for specific workloads. They are up to 30% faster for PostgreSQL databases, up to 60% faster for NGINX web applications, and up to 40% faster for AI deep learning recommendation models compared to R7i. R8i-flex, our first memory-optimized Flex instances, are the easiest way to get price performance benefits for a majority of memory-intensive workloads. They 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. R8i instances are a great choice for all memory-intensive workloads, especially for workloads that need the largest instance sizes or continuous high CPU usage. R8i instances offer 13 sizes including 2 bare metal and the new 96xlarge size for the largest applications. https://docs.aws.amazon.com/sap/latest/general/sap-hana-aws-ec2.htmland deliver 142,100 aSAPS, the highest among all comparable machines in on-premises and cloud environments, delivering exceptional performance for mission-critical SAP workloads. To get started, sign in to the https://aws.amazon.com/console/. Customers can purchase these instances via Savings Plans, On-Demand instances, and Spot instances. For more information about the new https://aws.amazon.com/ec2/instance-types/r8iinstances visit the AWS News https://aws.amazon.com/blogs/aws/best-performance-and-fastest-memory-with-the-new-amazon-ec2-r8i-and-r8i-flex-instances/.

Análisis post-mortem de la caída de AWS del pasado 20 de octubre: una «condición de carrera» en DynamoDB en dynamodb.us-east-1.amazonaws.com afectó a varios servicios DNS (EC2, Lambda…) del US‑East‑1 de AWS y se propagaron a Europa y otras regiones. Duración: 14 horas aws.amazon.com/es/message/1...

No expert here, but IAM can infiltrate into otherwise automated processes on AWS. Instance permissions (for example) use IAM to allow an EC2 machine access to protected resources elsewhere. So if IAM were to go down machines could conceivably lose critical access.

The problem started with misconfigured DNS, but soon infected EC2 launches as well, bringing hiccups to many of the largest internet services, #AWS.

tl;dr:
- Race condition in system that updates DNS records for DynamoDB instances causes deletion of key records
- DynamoDB becomes unavailable
- Tons of services relying on DynamoDB start to also go down (EC2, network load balancing, Lambda, ECS, EKS, Fargate, Connect, STS, IAM authn)

🆕 Amazon CloudWatch adds two free metrics to monitor EC2 instances hitting EBS I/O limits, helping spot issues and trigger actions like resizing. They track IOPS and throughput every minute.

#AWS #AmazonEc2 #AmazonCloudwatch #AwsGovcloudUs #AmazonElasticBlockStore
New Amazon CloudWatch metrics to monitor EC2 instances exceeding I/O performance
Today, Amazon announced two new Amazon CloudWatch metrics that provide insight into when your application exceeds the I/O performance limits for your EC2 instance with attached EBS volumes. These two metrics, Instance EBS IOPS Exceeded Check and Instance EBS Throughput Exceeded Check, monitor if the driven IOPS or throughput is exceeding the maximum EBS IOPS or throughput that your instance can support. With these two new metrics at the instance level, you can quickly identify and respond to application performance issues stemming from exceeding the EBS-Optimized limits of your instance. These metrics will return a value of 0 (performance not exceeded) or a 1 (performance exceeded) when your workload is exceeding the EBS-Optimized IOPS or throughput limit of the EC2 instance. With Amazon CloudWatch, you can use these new metrics to create customized dashboards and set alarms that notify you or automatically perform actions based on these metrics, such as moving to a larger instance size or a different instance type that supports higher EBS-Optimized limits. The Instance EBS IOPS Exceeded Check and Instance EBS Throughput Exceeded Check metrics are available by default at a 1-minute frequency at no additional charges, for all Nitro-based Amazon EC2 instances with EBS volumes attached. You can access these metrics via the EC2 console, CLI, or CloudWatch API in all Commercial AWS Regions, including the AWS GovCloud (US) Regions and China Regions. To learn more about these CloudWatch metrics, please visit the EC2 CloudWatch Metrics documentation.

Amazon EC2 C7i-flex instances are now available in the Asia Pacific (Jakarta) Region
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 Asia Pacific (Jakarta) Region. C7i-flex instances expand the EC2 Flex instances portfolio to 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’ Customer Carbon Footprint Tool now includes Scope 3 emissions data

AWS now tracks how guilty you should feel about your EC2 instances. Bonus: the carbon metrics are just as confusing as their pricing. At least Mother Earth can see your Lambda cold starts in the ozone layer.

Hot take: dont use aws useast 1. closest to #aws dev hq= deploy there 1st= most #outage there 1st. likely don't need latest+extra latency not critical & Most use basic ec2+rds+s3

Have stuff ready to go in at least 1 other #cloud zone so can failover: hard setup but worth it: at least works degraded

Another day, another round of AI bots (OpenAI and Perplexity, this time) downloading huge files from one of my open data websites over and over again, running up a big EC2 data transfer bill. I guess I'll have to put that site behind Cloudflare, too. :-/

I cannot wait to see how one of these machines handles the winding streets of EC2. I predict we'll find them piled up in Austin Friars like beached whales.
