This blog post proposes an ecommerce scenario with an Orders microservice, an Orders Rollback microservice and an Inventory microservice that communicate with each other. This communication happens while raising an order successfully or rolling back an order when the Inventory microservice reports an error. This communication is orchestrated with Amazon Simple Notification Service (Amazon SNS) […]

You can use CloudWatch Container Insights to monitor, troubleshoot, and alarm on your containerized applications and microservices. Amazon CloudWatch collects, aggregates, and summarizes compute utilization information like CPU, memory, disk, and network data. It also helps you isolate issues and resolve them quickly by providing diagnostic information like container restart failures. Container Insights gives you […]

Organizations are embracing microservices architectures and container-based deployments to gain agility, scalability, isolation, and separation of concerns. AWS Fargate, the serverless compute engine for running containers in the AWS Cloud, improves agility by taking away the undifferentiated heavy lifting of worker node provisioning and management. With Fargate, organizations can focus on building applications and application […]

When deploying containers to Amazon Elastic Container Service (Amazon ECS), customers have choices as to what level of management they want or need to have over the cluster compute. First there is AWS Fargate, which is a serverless compute engine that removes the need for customers to provision and manage servers. This approach simplifies the […]

Since the launch of AWS App2Container, customers have been asking for the ability to remotely manage the migrations of Java and .NET applications running on Windows or Linux hosts. Beginning with the version 1.2 of App2Container, users can accomplish containerization of their workloads without installing A2C software on the application servers. The remote execution feature […]

In this blog post, I’ll show you how to set up end-to-end encryption on Amazon Elastic Kubernetes Service(Amazon EKS). End-to-end encryption in this case refers to traffic that originates from your client and terminates at an NGINX server running inside a sample app. I work with regulated customers who need to satisfy regulatory requirements like […]

In digital advertising, the ad click-through rate (CTR) model predicts the probability of a click given the ads and context x (for example, shopping query, time of the day, device). The output of a CTR model can be seen as a conditional probability p(y = click|x). A precise estimation of this probability influences our ability […]

This post is co-authored by Alex Pollitt, Co-founder and CTO at Tigera, Inc. Recently Amazon announced support for Bottlerocket on Amazon Elastic Kubernetes Service (Amazon EKS). Bottlerocket is an open source Linux distribution built by Amazon to run containers focused on security, operations, and manageability at scale. You can learn more about Bottlerocket in this […]

Docker Hub has recently updated its terms of service to introduce rate limits for container image pulls. While these limits don’t apply to accounts under a Pro or Team plan, anonymous users are limited to 100 pulls per 6 hours per IP address, and authenticated free accounts are limited to 200 pulls per 6 hours. […]

Originally, containers were a great fit for stateless applications. However, for many use cases there is a need for persistent storage, without which stateful workloads are not possible. Kubernetes first introduced support for stateful workloads with in-tree volume plugins, meaning that the plugin code was part of the core Kubernetes code and shipped with the […]
