Feed: Recent Announcements. eksctl, the official CLI for Amazon Elastic Kubernetes Service (Amazon EKS), now lets you create node groups inside an Amazon EKS cluster by simply providing node requirements in vCPUs, memory, or GPUs. Additionally, eksctl now lets you preview the cluster configuration before creating a new cluster or a new node group by using the new dry-run mode. As a best practice, AWS recommends using multiple instance types when using Spot nodes for an EKS cluster to maximize availability with Spot Instances. Previously, you had to manually select instance types when creating node groups with multiple instance types ... Read More

Feed: AWS Architecture Blog. Organizations across every industry and sector are looking to easily and cost-effectively process vast amounts of data. Amazon EMR offers a way to instantly provision as much or as little capacity as needed to perform data- intensive tasks. When launching Amazon EMR, the IPs of the primary (master) and core node are automatically assigned at the starting point. However, you may need to set up static private IPs for an Amazon EMR cluster to connect to systems within your on-premises data center. For example, if your on-premises data center has firewall policies set to allow access ... Read More

Feed: Recent Announcements. Amazon ElastiCache now supports tag-based access control and adding tags to additional cluster resources. By using tags for access control, your AWS Identity and Access Management (IAM) users, groups, and roles get access only to the Amazon ElastiCache resources with matching tags. This provides you the capability to scale by reducing the number of distinct permissions you need to create and manage in your AWS account. You can define AWS IAM policies that grant or deny access to a resource based on its tags. Furthermore, you can use specific condition context keys to customize your AWS IAM ... Read More

Feed: AWS Partner Network (APN) Blog. Author: Krishna Doddapaneni. By Krishna Doddapaneni, Partner Solutions Architect – AWSBy Jared Knapp, Partner Solutions Architect – AWSBy Rob Boville, Head of Engineering and Architecture – ADLINK Issues on a conveyor belt-driven production line can easily be missed or overlooked, leading in some cases to damaged products and costly repairs. Those issues can be classed into two categories: Problems with the product that has been manufactured. Problems with the conveyor which requires maintenance. The resulting downtime can be costly and lead to missed production targets. Manual quality inspections can help prevent some of these ... Read More

Feed: AWS Architecture Blog. Scaling based on Amazon Simple Queue Service (SQS) is a commonly used design pattern. At AWS Professional Services, we have recently used a variant of this pattern to achieve highly parallel computation for larger customers. In fact, any use case with a tree-like set of entities can use this pattern. It’s useful in a workflow where all nodes between the root and leaves must be processed rapidly and in parallel. Some use cases would be database parent-child records or graph relationships. Let us explore a couple of example scenarios, both hypothetical (COVID contact tracing) and real ... Read More

Feed: AWS Public Sector Blog. Author: Jason Chin. One of the biggest scientific achievements of the twenty-first century was the completion of the Human Genome Project and the publication of a draft human genome. The project took over 13 years to complete and remains one of the largest private-public international collaborations ever. Advances since in sequencing technologies, computational hardware, and novel algorithms reduced the time it takes to produce a human genome assembly to only a few days, at a fraction of the cost. This made using the human genome draft for precision and personalized medicine more achievable. Researchers derived the ... Read More

Feed: AWS Architecture Blog. In Part I of this two-part blog, we outlined best practices to consider when building resilient applications in hybrid on-premises/cloud environments. We also showed you how to adapt mindsets and organizational culture. In Part II, we’ll provide technical considerations related to architecture and patterns for resilience in AWS Cloud. Considerations on architecture and patterns The AWS Well-Architected Framework defines resilience as having “the capability to recover when stressed by load (more requests for service), attacks (either accidental through a bug, or deliberate through intention), and failure of any component in the workload’s components.” Resilience is an ...
