**Celebrating open source contributors**

The articles and projects shared in this newsletter are only possible thanks to the many contributors in open source. I would like to shout out and thank those folks who really do power open source and enable us all to learn and build on top of what they have created. 

So thank you to the following open source heroes: Avijit Goswami, Ajit Tandale, Thippana Vamsi Kalyan, Jannik Wempe, Ran Isenberg, Greg Biegel, Aneel Murari, Rahul Popat, Matthew Overstreet, Mikhail Shapirov, Amir Shenavandeh, Amit Maindola, Melody Yang, Jianwei Li, Krish K B, Narayanan Venkateswaran, Partha Sarathi Sahoo, Phil Basford, Gary Stafford, Mohamed Radwan, Daniele Frasca, Artur Rodrigues, and Stan Girard.

### Latest open source projects

*The great thing about open source projects is that you can review the source code. If you like the look of these projects, make sure you that take a look at the code, and if it is useful to you, get in touch with the maintainer to provide feedback, suggestions or even submit a contribution.*

#### Tools

**aws-ecr-cleaner**

[aws-ecr-cleaner](https://aws-oss.beachgeek.co.uk/23q) this is a super useful open source project from DevOpsBox that helps you keep on top of your container image repository, specifically Amazon ECR. This tool augments capabilities such as ECR Lifecycle policies. Currently Amazon ECS, AWS Lambda, and App Runner are supported. Make sure you check out this tool if you use Amazon ECR. 

**dotnet-lambda-sql-server-proxy**

[dotnet-lambda-sql-server-proxy](https://aws-oss.beachgeek.co.uk/23m) this project from James Eastham enables Lambda functions to connect to SQL databases without having to manage the connections.

The recent release of RDS Proxy for SQL Server opens up a new, powerful set of possibilities for running .NET applications on AWS Lambda. As a default, AWS Lambda allows up to 1000 concurrent executions. If you are running an application using SQL Server these 1000 concurrent executions will create 1000 separate SQL connections, this can quickly exhaust the connection pool of your database. RDS for SQL Server does not support IAM based authentication. This means for applications using SQL server connection strings need to be managed and credentials stored somewhere, ordinarily either SSM Parameter Store or Secrets Manager.

RDS Proxy solves these two challenges. First, connections are pooled within the proxy. Meaning as Lambda scales connections to the underlying database can be re-used. Secondly, RDS Proxy supports IAM based authentication. This enables us to authenticate our application using IAM roles and policies.

Check out the docs for more details.

**amazon-transcribe-streaming-live-closed-captions**

[amazon-transcribe-streaming-live-closed-captions](https://aws-oss.beachgeek.co.uk/23o) this sample project will inject live closed captioning to an input video stream, and send the combined output to a destination.

**fine-grained-authorization-apigw-lambda-dynamodb**

[fine-grained-authorization-apigw-lambda-dynamodb](https://aws-oss.beachgeek.co.uk/23i) AWS Community Builder Daniele Frasca shares this project that looks like its written in Rust, that helps you enable fine-grained authorisation using any Identity and Access Management solution with API Gateway.

**graphql-lambda-java-sample**

[graphql-lambda-java-sample](https://aws-oss.beachgeek.co.uk/231) this repository consists of sample code for three applications. 1/ Self managed GraphQL API running on AWS Lambda, 2/ AWS AppSync hosted GraphQL API with Direct Lambda Resolvers, and 3/ AWS AppSync hosted GraphQL API with RDS Resolver. To help you get started, check out the accompanying blog post, [Building a GraphQL API with Java and AWS Lambda](https://aws-oss.beachgeek.co.uk/232), where Aneel Murari and Rahul Popat guide you through these three options for running a GraphQL application on AWS using serverless technologies.

![architecture of graphql-lambda](https://d2908q01vomqb2.cloudfront.net/0a57cb53ba59c46fc4b692527a38a87c78d84028/2022/09/26/mobile_1662_2-1.jpg)

**trusted-advisor-asana-task**

[trusted-advisor-asana-task](https://aws-oss.beachgeek.co.uk/23n) Trusted Advisor(TA) inspects your AWS environment, and then makes recommendations when opportunities exist to save money, improve system availability and performance, or help close security gaps. High priority TA checks require further investigation as they help you secure and optimise your account to align with AWS best practices. Engineering teams often dedicate resources to manually go through the TA recommendations to detect and handle the recommendations. Further, some of the less severe issues could be parked for a later date and needs to be tracked as a backlog item. 

If your team is already using Asana to manage all the work from company strategy to sprint plans and support issues, this solution automates the process to get notified on TA recommendations as a part of the same Asana ecosystem in the form of Asana tasks. This removes the need for manual intervention and enables teams to easily track, and provides visibility to the teams to address the issues in a timely manner.

![architecture of solution to integrate asana with ta](https://user-images.githubusercontent.com/108042843/192427607-be22d5a8-e099-4cee-9ed1-03530513ff7d.png)

### Quick updates

**Linux**

AWS Snow Family now offers the Snow Amazon Linux 2 (AL2) Amazon Machine Image (AMI) for all Snowball Edge and Snowcone jobs. With this launch, customers can get started running edge workloads on Snow devices using the Snow AL2 AMI. The Snow AL2 AMI is maintained and provided by AWS Snow, making it easier for customers who do not want to create their own AMI for Snow devices.

Prior to this launch, customers had a 2-step process to provisioning AMIs on Snow jobs. First, customers had to create their own AMI from Ubuntu or CentOS offerings from AWS Marketplace and then select these AMIs as part of the Snow job order. This 2-step process provided more control to the customers in selecting the right AMIs for their jobs. For customers not familiar with the AMI creation process, the 2-step process required more preparation before placing a Snow job order with AMIs on them. Now, customers who do not want to bring their own AMIs to a Snow job can add a Snow AL2 AMI to their Snow job with 1-click selection at the time of job ordering.

**Ubuntu**

Amazon WorkSpaces now offers support for Ubuntu Desktop 22.04 LTS. Ubuntu is a popular Linux distribution published by Canonical and the first third-party Linux operating system supported by Amazon Workspaces. With this launch, Amazon WorkSpaces customers now have the flexibility to select Amazon Linux, Microsoft Windows, or Ubuntu desktops depending on the specific needs of their end users. Customers can easily provision and scale Ubuntu WorkSpaces for developers, data scientists, and engineers as high-performance cloud-based development desktops, or for other non-technical users as general-purpose desktops.

Read more in the official launch post, [Amazon WorkSpaces Introduces Ubuntu Desktops](https://aws-oss.beachgeek.co.uk/23u) or the news release [AWS introduces Ubuntu Desktop for Amazon WorkSpaces](https://aws-oss.beachgeek.co.uk/23w)

![demo of amazon workspace running ubuntu](https://d2908q01vomqb2.cloudfront.net/da4b9237bacccdf19c0760cab7aec4a8359010b0/2022/09/07/2022-09-07_12-32-39-1024x588.png)

**Bottlerocket**

Bottlerocket, a Linux-based operating system that is purpose built to run container workloads, is now integrated with Amazon Inspector. Customers that have Inspector EC2 scanning already enabled do not need to take any additional action. If Amazon Inspector discovers a vulnerability, it will recommend an update to the version of Bottlerocket that fixes that vulnerability.

Amazon Inspector is a vulnerability management service that scans EC2 and container workloads for software vulnerabilities and unintended network exposure. Amazon Inspector leverages the AWS System Manager (SSM) agent to scan for vulnerabilities. In Bottlerocket hosts, the SSM agent runs within the control host container, so you need to make sure it is enabled in your hosts.

**MySQL**

You can now perform an in-place upgrade of your Amazon Aurora  database cluster from Amazon Aurora MySQL-Compatible Edition 2 (with MySQL 5.7 compatibility) to Aurora MySQL-Compatible Edition 3 (with MySQL 8.0 compatibility). Instead of backing up and restoring the database to the new version, you can upgrade with just a few clicks in the Amazon RDS Management Console or by using the AWS SDK or CLI.

MySQL 8.0 offers improved performance functionality from enhancements such as instant DDL and adds developer productivity features such as window functions. It also includes JSON functionality additions, new security capabilities, and more. MySQL 8.0 on Aurora MySQL-Compatible Edition supports popular Aurora features including Aurora Serverless v2, Global Database, RDS Proxy, Performance Insights, and Parallel Query.

To upgrade to Aurora MySQL Version 3 (compatible with MySQL 8.0), select the "Modify" option on the AWS Management Console corresponding to the database cluster you want to upgrade, choose the version of Aurora MySQL Version 3 you want to upgrade to, and proceed with the wizard. The upgrade may be applied immediately (if you select the "Apply Immediately" option), or during your next maintenance window (by default).

**PHP**

AWS X-Ray now support tracing end-to-end requests in PHP applications via the AWS Distro for OpenTelemetry (ADOT) in public preview. ADOT is a secure, AWS-supported distribution of the OpenTelemetry project. With this launch, you can now use the OpenTelemetry PHP SDK to instrument your PHP applications for tracing with X-Ray. X-Ray will help you to visualise and debug your distributed PHP applications in the CloudWatch console with its service map and trace analytics tools.

Customers can now use the AWS-supported OpenTelemetry components necessary to export trace data to AWS X-Ray, such as the X-Ray ID generator, X-Ray propagator, and resource detectors for Amazon ECS, Amazon EKS, Amazon EC2, and AWS Lambda services. Customers can also use the AWS SDK for PHP to trace requests made to the AWS SDK without the need to manually record each request. By using ADOT, applications can be easily configured to export traces to AWS X-Ray.

Check out the release post, [AWS X-Ray launches support for tracing PHP applications via OpenTelemetry in public preview](https://aws-oss.beachgeek.co.uk/23x). This provides links to resources to get you started.

**awscii-cli**

[awscii-cli](https://github.com/mhlabs/awscii-cli) is a command line tool that lets you render predefined AWS graphs in ASCII art using asciichart. In addition to  #AWS #Lambda, #DynamoDB, #APIGateway, awscii-cli has now added Kinesis Data Streams metrics to list of service metrics it can visualise.
