A Guide to Root Access for AWS S3 Buckets

Root access in AWS S3 refers to the permissions granted to the root user of an AWS account.
Risks of root access include accidental data loss, unauthorized access, and lack of accountability.
Best practices for managing root access include limiting the use of the root account, enabling MFA, creating IAM users with specific permissions, monitoring account activity, using bucket policies and ACLs, periodically reviewing permissions, and utilizing AWS Organizations for multi-account management.
Root access to AWS S3 buckets comes with significant power and responsibility, and following best practices helps protect data and maintain a secure cloud environment.

Use Amazon Q developer and AWS Infrastructure Composer to automate the monitoring of available IP addresses in Subnets.

The author details a solution to monitoring the available IP addresses in subnets without the use of IPAM by utilising Amazon Q Developer and AWS Infrastructure Composer and discusses a problem which arises from IP exhaustion when subnets run out of IPs.
The author created a Lambda Function which obtains data on subnet, IP address, and name. This data is returned to AWS EventBridge which uses CloudWatch metrics to validate available IP addresses.
In order to monitor the IP utilization, the script sends cloudwatch metrics to the CloudWatch console via the cloudwatch.put_metric_data method.
The deployment process was designed using AWS Infrastructure Composer which allows infrastructure to be visualised and to generate Infrastructure as Code that can be deployed using AWS Serverless Application Model (AWS SAM).
Parameters for the deployed solution include the VPC ID, CloudWatch Metric Namespace, email address to receive alerts, and more.
The author also demonstrates a demo of the solution by showing how IP utilization can be monitored in CloudWatch when triggered by an alarm.
The author suggests that notifications can be sent to other platforms, such as Slack or PagerDuty.
The author hopes that this automation solution will assist someone who wishes to monitor IP address utilization in subnets without using IPAM.
However, the author wishes that metrics straight from CloudWatch were available.
The author calculated the cost, which appears to be quite reasonable.

Effortless Debugging: AWS CDK TypeScript Projects in VSCode

Debugging Lambda functions should be easy, right? You want to debug as you develop, using a standard editor (VSCode), a popular IaC framework (AWS CDK), and a widely adopted language (TypeScript).
The main challenges to wider serverless adoption is the developer experience itself.
The guide helps to set up a smooth, flexible debugging environment with AWS CDK TypeScript Projects in VSCode.
The sample project uses two different debugging options, one by running function locally and debugging locally using AWS SAM, and the other by running function remotely and debugging locally using Lambda Live Debugger.
The starter project provides a CDK configuration with an example resource stack (API Gateway -> Lambda -> SQS).
The developer experience is simplified with 4 main requirements: quick debugging, no deployment or hot-swap requirement, support for multi-developer environment, local debugging with remote resources.
The reusable CustomLambda construct is based on the CDK NodejsFunction, bundling with ESBuild and including Lambda Powertools. This saves crucial seconds when initiating the debug run.
AWS SAM to invoke the Lambda function locally provides quick debugging without running cdk synth every time.
Lambda Live Debugger offers the added benefit of validating permissions set up in CDK by running the Lambda functions remotely.
Lambda Live Debugger automatically reloads the updated code without the need to redeploy or restart the debugger.

The death of Moore’s Law is finally starting to stink

Moore's Law, which is the number of transistors in a chip would double about every two years, isn't cleanly dying like one might expect and instead is somewhat awkward and ongoing.
We have two brand new generations from AMD and Intel, neither of which really came out of the gate swinging.
Even within just a few years, the rate of performance improvements has slowed considerably.
AMD and Intel may not talk about it publicly, but both companies clearly see the writing on the walls.
That's likely why Intel pivoted to a hybrid architecture in the first place.
And for AMD's part, it's no secret that 3D V-Cache has become a defining technology for the company's CPUs, and it's a clear way to skirt the bottleneck of Moore's Law.
A function of space - You cannot separate the number of transistors from the size of the die.
Moore's Law is dead, PC hardware is getting more expensive, and everything sucks - that's not how I want to leave this.
But AI also represents a way to bring a new form of computing.
It really doesn't matter if Moore's Law is dead or alive and well - if companies like AMD, Intel, and Nvidia want to stay afloat, they'll continually need to think of solutions to address rising performance demands.
