Introduction

Automated deployments are the backbone of a strong DevOps environment. Without efficient, reliable, and repeatable software updates, engineers need to redirect their focus from developing new features to managing and debugging their deployments. Amazon first faced this challenge many years ago. When making the move to a service-oriented architecture, Amazon refactored its software into small independent services and restructured its organization into small autonomous teams. Each team took on full ownership of the development and operation of a single service, and they worked directly with their customers to improve it.

Apache Spark is an open-source lightning-fast cluster computing framework built for distributed data processing. With the combination of Cloud, Spark delivers high performance for both batch and real-time data processing at a petabyte scale. Spark on Kubernetes is supported from Spark 2.3 onwards, and it gained a lot of traction among enterprises for high performance and […]

This post describes our migration journey of Spark from EMR on EC2 to EMR on EKS.

I want to sort captured traffic on #packet sent through ports. How can I filter this in wireshark? Edit 1: I have captured traffic, I want to find most port sending packet from specific Address.

Wireshark represents the world’s most used protocol analyzer. By using it, you can check everything that’s going on within your network, troubleshoot different problems, analyze and filter your network traffic using various tools, etc. If you want to

Containers are a de facto standard in cloud application development and deployment. Publishing software in container images provides developers an integrated packaging solution, bundling software and all required dependencies into a portable image format. This image can then be run anywhere, abstracting away the infrastructure-specific aspects of deployment. However, the promise of running anywhere only […]

A workshop to build Cost Intelligence dashboards in Quicksight for common AWS services

AWS Cost Explorer helps you manage your AWS costs by giving you detailed insights into the line items in your bill. In Cost Explorer, you can visualize daily, monthly, and forecasted spend by combining an array of available filters. Filters allow you to narrow down costs according to AWS service type, linked accounts, and tags. […]

A common challenge architects face when designing a Kubernetes solution on AWS is how to grant containerized workload permissions to access an AWS service or resource. AWS Identity and Access Management (IAM) provides fine-grained access control where you can specify who can access which AWS service or resources, ensuring the principle of least privilege. The challenge […]

We announced a new Amazon Inspector last week at re:Invent 2021 with improved vulnerability management for cloud workloads.
