Finally, check the events section for details of up and coming events you do not want to miss, including next week's second episode of Build on AWS open source.

**Feedback**

If you enjoy reading this newsletter, please let me know how we can improve it as well as how AWS can better work with open source projects and technologies by completing [this very short survey ](https://eventbox.dev/survey/NUSZ91Z)that will take you probably less than 30 seconds to complete. Thank you so much!

**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: Rosius Ndimofor, Suraj Narwade, Lars Jacobsson , Kyle Weller, Gary Stafford, Zach Mitchell, Aaron Miller, Siva Guruvareddiar, Luke Popplewell, Dillon Nys, Abdallah Shaban, Ashish Nanda, Harshad Gohil, John Lonappan, Daniel Lorch, James Eastham, Sai Vennam, Suzanne Daniels, Himanshu Mishra, Bryan Landes, Suman Debnath, Bimal Gajjar, Shane Miller

### 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

**AWSGoat**

[AWSGoat](https://aws-oss.beachgeek.co.uk/1ze) is an open source project that aims to help you better understand the thread landscape of your AWS environments. Compromising an organization's cloud infrastructure is like sitting on a gold mine for attackers. Sometimes a simple misconfiguration or a vulnerability in web applications is all an attacker needs to compromise the entire infrastructure. Since the cloud is relatively new, many developers are not fully aware of the threatscape and they end up deploying a vulnerable cloud infrastructure.

AWSGoat is a vulnerable by design infrastructure on AWS featuring the latest released OWASP Top 10 web application security risks (2021) and other misconfiguration based on services such as IAM, S3, API Gateway, Lambda, EC2, and ECS. AWSGoat mimics real-world infrastructure but with added vulnerabilities. It features multiple escalation paths and is focused on a black-box approach.

There are plenty of other news posts that mentioned this project, and I found this one, [AWSGoat Open-Source Project for Pen Testing AWS Cloud Solutions](https://aws-oss.beachgeek.co.uk/1zw), particular helpful. 

**cw-logs-insights-snippets**

[cw-logs-insights-snippets](https://aws-oss.beachgeek.co.uk/202) is an AWS SAM project from AWS Community Builder Lars Jacobsson that adds the snippets from serverlessland.com/snippets as saved queries in CloudWatch Logs. Serverlessland.com/snippets hosts a growing number of community provided snippets. Many of these are useful CloudWatch Logs Insights snippets. Until AWS integrates these in the console natively you can use this stack to get them there.

![demo of cw-logs-insights](https://github.com/ljacobsson/cw-logs-insights-snippets/blob/main/images/demo.gif?raw=true)

**kubectl-eks**

[kubectl-eks](https://aws-oss.beachgeek.co.uk/203) is kubectl plugin for Amazon EKS from AWS Community Builder Suraj Narwade.

**streaming-sales-generator**

[streaming-sales-generator](https://aws-oss.beachgeek.co.uk/201) is a handy tool from Gary Stafford that generates sample streaming sales data for Apache Kafka, written in Python. Each time you want to explore or demonstrate a new streaming technology, you must first find an adequate data source or develop a new source. Ideally, the streaming data source should be complex enough to perform multiple types of analyses on and visualise different aspects with Business Intelligence (BI) and dashboarding tools. Additionally, the streaming data source should possess a degree of consistency and predictability while still displaying a reasonable level of natural randomness. Conversely, the source should not result in an unnatural uniform distribution of data over time. This project's highly configurable synthetic data generator (producer.py) streams beverage products, semi-random beverage sales transactions, and inventory restocking activities to Apache Kafka topics. It is designed for demonstrating streaming data analytics tools, such as Apache Spark Structured Streaming, Apache Beam, Apache Flink, Apache Pinot, Databricks, Google Cloud Dataproc, and Amazon Kinesis Data Analytics.

Check out the docs, which include a short video to show you how you can get this tool up and running

**amazon-ec2-instance-selector**

[amazon-ec2-instance-selector](https://aws-oss.beachgeek.co.uk/200) is a CLI tool and go library which recommends instance types based on resource criteria like vcpus and memory. There are over 270 different instance types available on EC2 which can make the process of selecting appropriate instance types difficult. Instance Selector helps you select compatible instance types for your application to run on. The command line interface can be passed resource criteria like vcpus, memory, network performance, and much more and then return the available, matching instance types. Check out the repo for plenty of examples of how you can use this command.

**merloc**

[merloc](https://aws-oss.beachgeek.co.uk/1zg) AWS Hero [Serkan Özal](https://aws-oss.beachgeek.co.uk/1zf) tweeted about this new project just before I disappeared on holiday. In his tweet he says:

> I am thrilled to announce @thundraio MerLoc an AWS Lambda local development, testing, debugging and hot-reload tool to build and ship #serverless applications faster without need to add console logs and re-deploys after changes 

MerLoc is a live AWS Lambda function development and debugging tool. MerLoc allows you to run AWS Lambda functions on your local while they are still part of a flow in the AWS cloud remote. Looks very interesting indeed.

![architecture of merloc](https://github.com/thundra-io/merloc/blob/master/assets/architecture.png?raw=true)

**automated-iam-access-analyzer**

[automated-iam-access-analyzer](https://aws-oss.beachgeek.co.uk/208) is a sample implementation of a periodical monitoring of an AWS IAM Role in order to achieve a continuous permission refinement of that role. The goal of the solution is to present an operational, continuous least-privilege approach for a particular role in order to provide for security proliferation in an ongoing manner. Automated IAM Access Analyzer relies on the AWS CloudTrail, AWS IAM Access Analyzer for policy generation, and AWS Step Functions for orchestrating the overall process.


**aws_signature_v4**

[aws_signature_v4](https://aws-oss.beachgeek.co.uk/1zm) is an open source implementation of the AWS Signature Version 4 protocol in the Dart programming language. The SigV4 signer is a library which developers can include in their projects to sign and send HTTP requests to AWS services using their AWS credentials. To get you started, check out the post [Introducing the AWS SigV4 Signer for Dart](https://aws-oss.beachgeek.co.uk/1zn) from Dillon Nys, Abdallah Shaban, and Ashish Nanda. 

![demo of library of sigv4 for dart](https://d2908q01vomqb2.cloudfront.net/ca3512f4dfa95a03169c5a670a4c91a19b3077b4/2022/08/22/s3blog1.gif)

### Demos, Samples, Solutions and Workshops

**serverless-batch-cost-guardian**

[serverless-batch-cost-guardian](https://aws-oss.beachgeek.co.uk/206) this repo has the code that will deploy and provide a serverless solution that watches jobs in an AWS Batch (Fargate-only) compute environment, and if an AWS Budget threshold is close to being met, will kick in a high-frequency cost checker to stop all jobs before the budget is met. This solution is meant to be a safeguard for long-running jobs and can evaluate Budget status at a much higher rate than AWS Billing's 2-3 daily limit with 6-8 hour granularity.

![architecture of serverless batch cost guardian](https://github.com/aws-samples/serverless-batch-cost-guardian/blob/main/images/event-driven-budget-checker-architecture.png?raw=true)

**graviton2-based-ecommerence-solution**

[graviton2-based-ecommerence-solution](https://aws-oss.beachgeek.co.uk/207) if you are looking for some code for a sample e-commerce solution that leverages AWS Graviton2, then check out this repo. It provides the code from the Graviton2-based-ecommerence-solution Workshop which you will find links for in the README.

![architecture for graviton ecommerce](https://github.com/aws-samples/graviton2-based-ecommerence-solution/blob/main/resource/Architecture.png?raw=true)

**aws-mainframe-modernization-carddemo**

[aws-mainframe-modernization-carddemo](https://aws-oss.beachgeek.co.uk/209) is a Mainframe application designed and developed to test and showcase AWS and partner technology for mainframe migration and modernisation use-cases such as discovery, migration, modernisation, performance test, augmentation, service enablement, service extraction, test creation, test harness, etc. I am a big fan of retro computing, and this project really appeals so I need to try and figure out how I can get this one up and running - watch this space!

**sam_stepfunctions**

[sam_stepfunctions](https://aws-oss.beachgeek.co.uk/204) AWS Hero Rosius Ndimofor shares a simple Step functions workflow written in SAM and Python for an apartment booking application.

**gitops-amazon-ecs-sample**

[gitops-amazon-ecs-sample](https://aws-oss.beachgeek.co.uk/205) is a repo that helps you create a single pipeline to deploy multiple services on Amazon ECS using gitops. What problem is this repo trying to solve? Certain Organizations need to test and deploy multiple, sometimes hundreds of micro-services simultaneously. This could be because of regulatory or compliance requirements where the organisation is mandated to test numerous services together and then release it in one go. Using the traditional strategy of deploying one pipeline per micro-service requires these organisations to coordinate hundreds of pipelines to do a single production release. This increases the deployment window, deployment complexity, and requires coordination from multiple teams that own these micro-services. For example, if 50 services must be deployed in a release, then it would require the team to go and approve 50 production approval gates, which can be a time-consuming and error-prone process. In the case of rollback, it would take considerable time to go and individually rollback each of the pipelines to do a full rollback of the release. These organisations need the ability to reliably deploy multiple services together without the complexity of having to orchestrate numerous pipelines during release. Certain GitOps deployment tools like ArgoCD can facilitate the deployment of multiple services in the Kubernetes space. However, these tools are limited in the Amazon ECS space. This repo attempts to create a single pipeline to provide the ability to deploy multiple Amazon ECS Fargate services and scheduled tasks simultaneously with Git as the source of truth. This is done to reduce the complexity associated with deploying multiple services in a release.

### AWS and Community blog posts

**dbt**

In the first of two posts this week from a writer who regular reader of this newsletter will know, Gary Stafford explores how dbt makes it easy to transform data and materialise models in a modern cloud data lakehouse built on AWS in his post [Lakehouse Data Modeling using dbt, Amazon Redshift, Redshift Spectrum, and AWS Glue](https://aws-oss.beachgeek.co.uk/1zy). [hands on]

![screenshot of dbt from the blog post](https://miro.medium.com/max/1400/1*F6HZZyQT68phkXvQSU-VcA.png)

Following that, Gary put together the post[ dbt and Amazon Redshift Serverless: Serverless Lakehouse Data Modeling](https://aws-oss.beachgeek.co.uk/1zz) which explores the integration of dbt with Amazon Redshift Serverless. [hands on] As always, both posts are recommended reading this week.

**Open Source Lakehouses**

Kyle Weller from Onehouse has put together this very nice post, [Apache Hudi vs Delta Lake vs Apache Iceberg - Lakehouse Feature Comparison](https://aws-oss.beachgeek.co.uk/1zx), that has a very comprehensive list of features that you might looking for and how each of these open source projects currently meets those, as well as taking a look at some real life use cases and customer stories. I think this post could be useful as you look to explore and think about how you might evaluate these technologies.

**Jupyter**

Interactive Sessions for Jupyter is a new notebook interface in the AWS Glue serverless Spark environment. This enables a  serverless Spark backend to Jupyter notebooks and Jupyter-based IDEs such as Jupyter Lab, Microsoft Visual Studio Code, JetBrains PyCharm, and more. In the post, Introducing AWS Glue interactive sessions for Jupyter, Zach Mitchell shows you how to quickly get started installing via the command line and then running through some interactive notebooks. [hands on]

**Flyway**

Flyway is an open-source database SQL deployment tool. In the post, [Automate schema version control and migration with Flyway and AWS Lambda on Amazon Aurora PostgreSQL](https://aws-oss.beachgeek.co.uk/1zo), Harshad Gohil and John Lonappan share more details about this open source project and its capabilities, before showing you how you can set up Flyway along with an AWS Lambda function to deploy SQL scripts into various Amazon Aurora PostgreSQL-Compatible Edition environments. [hands on]

![architecture of flyaway](https://d2908q01vomqb2.cloudfront.net/887309d048beef83ad3eabf2a79a64a389ab1c9f/2022/08/23/DBBLOG-2254-image001.png)

**Ray**

In the post, [Scaling AI and Machine Learning Workloads with Ray on AWS](https://aws-oss.beachgeek.co.uk/1zs), Chris Fregly, Antje Barth, Apoorva Kulkarni, and Simon Zamarin highlight AWS contributions to the scalability and operational efficiency of Ray on AWS. 

**OpenAPI/Swagger**

In the post, [Deploy and manage OpenAPI/Swagger RESTful APIs with the AWS Cloud Development Kit](https://aws-oss.beachgeek.co.uk/1zl), Luke Popplewell demonstrates how AWS Cloud Development Kit (AWS CDK) Infrastructure as Code (IaC) constructs and AWS serverless technology can be used to build and deploy a RESTful Application Programming Interface (API) defined in the OpenAPI specification. [hands on]

![architecture of solution for OpenAPI / Swagger](https://d2908q01vomqb2.cloudfront.net/7719a1c782a1ba91c031a682a0a2f8658209adbf/2022/08/18/devops_2096_1.png)

**Keycloak**

Keycloak is an open source identity and access management solution for modern services and applications with a large and active open source community. Keycloak uses open protocol standards like OpenID Connect and SAML 2.0. It provides features including single sign-on (SSO), user federation, and identity brokering. It also provides both an admin console and an account management console. In the post, [Authenticating with Amazon Managed Grafana Using Open Source Keycloak on Amazon EKS](https://aws-oss.beachgeek.co.uk/1zh) Aaron Miller and Siva Guruvareddiar walk you through the steps to deploy and configure Keycloak on Amazon EKS to serve as the SAML authentication provider for Amazon Managed Grafana. [hands on]

![architecture of keycloak solution](https://d2908q01vomqb2.cloudfront.net/ca3512f4dfa95a03169c5a670a4c91a19b3077b4/2022/08/15/Keycloak-on-AWS-architecture-diagram-1024x779.png)

**CollectD**

CollectD is an open-source system statistics collection daemon. When running java workloads, the JVM exposes runtime metrics, such as the heap memory usage, thread count, and classes, through a standard API interface called the Java Management Extension (JMX). In this post, [Deliver Java JMX statistics to Amazon CloudWatch using the CloudWatch Agent and CollectD](https://aws-oss.beachgeek.co.uk/1zp), Daniel Lorch shows you how you can CollectD to collect metrics from JMX and send them to the Amazon CloudWatch agent, as well as allows namespacing metrics per application. Very nice post. [hands on]

![demo of cloudwatch alarms for collectd](https://d2908q01vomqb2.cloudfront.net/972a67c48192728a34979d9a35164c1295401b71/2022/08/30/cloudwatch-alarms.gif)

### Quick updates

**AWS SDK for pandas**

AWS Data Wrangler is now AWS SDK for pandas (awswrangler). We’re changing the name we use when we talk about the library, but everything else will stay the same. You’ll still be able to install using pip install awswrangler and you won’t need to change any of your code. As part of this change, we’ve moved the library from AWS Labs to the main AWS GitHub organisation but, thanks to the GitHub’s redirect feature, you’ll still be able to access the project by its old URLs until you update your bookmarks.

AWS SDK for pandas is a popular open source library that enables customers to connect to AWS data and analytics services to obtain data in a pandas dataframe. Customers can then use the pandas library to transform their data before writing back to an AWS service, Used by data scientists, data engineers and developers, AWS SDK for pandas allows easy data movement between 19 types of data store, including Amazon S3, Amazon Athena, Amazon Neptune, Amazon SageMaker, AWS Glue and AWS Lake Formation.

**Linux**

AWS announced the general availability of the credentials-fetcher open source project. As you modernise your .NET applications to Linux containers, you no longer need to worry about Microsoft Active Directory (AD) dependency. You can use credentials-fetcher to access AD from services hosted on Linux containers using the service account authentication model. This package makes it possible to create kerberos tickets specific to group managed service accounts (gMSAs) in applications running on Linux containers. As part of our launch, the credential-fetcher in packaged in RPM format and added it to Fedora Linux. You can install this package by using dnf install credentials-fetcher. A group managed service account is a managed account that provides automatic password management, service principal name (SPN) management, and the ability to delegate management to administrators over multiple servers or instances.

**Karpenter**

Karpenter is a flexible, high-performance Kubernetes cluster autoscaler that helps improve application availability, operational overhead, and cluster compute utilisation by launching new EC2 instances that are best fit to the scale, scheduling, and resource requirements of the workloads in a cluster. Customers can use Karpenter with Amazon Elastic Kubernetes Service (EKS) or any conformant Kubernetes cluster. Starting with v0.15.0, Karpenter will automatically consolidate Kubernetes cluster workloads onto new EC2 instances to help increase utilisation and lower cluster compute costs. 

As the workloads in a Kubernetes cluster change and scale, it can be necessary to launch new EC2 instances to ensure they have the compute resources they need. Over time, those instances can become under-utilised as some workloads scale down or are removed from the cluster. Workload consolidation for Karpenter automatically looks for opportunities to reschedule these workloads onto a set of more cost-efficient EC2 instances, whether they are already in the cluster or need to be launched. Consolidation for Karpenter can be enabled with a simple configuration change in the Karpenter Provisioner Custom Resource Definition (CRD) in Karpenter v0.15.0 and above.

**Kubernetes**

AWS App Mesh is a service mesh that provides application-level networking to make it easier for your services to communicate with each other across multiple types of compute infrastructure. AWS App Mesh standardises how your services communicate, giving you end-to-end visibility and options to tune for high-availability of your applications. 

You can now define a listener per each application port on your AWS App Mesh Virtual Gateways, Virtual Nodes and Virtual Routers, and define traffic routes to a specific listener. You can configure each listener independently, secure them with individual TLS certificates, and collect traffic metrics separately for each application port.

AWS App Mesh has also introduced support for customisable Envoy access log format for Virtual Nodes and Virtual Gateways. It enables you to diagnose your services with customised logging focusing on specific aspects that are important to you. Now you can specify the desired access log pattern using any Envoy command operators. You can also use JSON or text format to define the pattern. This configuration makes it easier to export the Envoy access log file to other tools for further analysis, which may require a specific format or pattern.

**Bottlerocket**

Bottlerocket, a Linux-based operating system that is purpose built to run container workloads, now has a Center for Internet Security (CIS) Benchmark. The CIS Benchmark is a catalog of security-focused configuration settings that help Bottlerocket customers configure or document any non-compliant configurations in a simple and efficient manner. The CIS Benchmark for Bottlerocket includes both Level 1 and Level 2 configuration profiles. 

**PostgreSQL**

Amazon Relational Database Service (Amazon RDS) for PostgreSQL now supports PostgreSQL minor version 14.4. We recommend you upgrade to this latest minor version to fix known security vulnerabilities and bugs from prior versions of PostgreSQL. While this release from PostgreSQL community includes a number of fixes, a noteworthy fix included in this release is for CREATE INDEX CONCURRENTLY and REINDEX CONCURRENTLY that can potentially cause silent data corruption of indexes. Amazon RDS has made the fix for the index corruption available since the release of Amazon RDS for PostgreSQL 14.3.

**AWS SAM**

The AWS Serverless Application Model (SAM) Command Line Interface (CLI) announces general availability of esbuild support in SAM CLI. The AWS SAM CLI is a developer tool that makes it easier to build, test, package, and deploy serverless applications. Esbuild, “an extremely fast JavaScript bundler”, links JavaScript ( js , jsx , ts , and tsx ) and CSS dependencies as deployable assets for the web. Starting today, you can now use esbuild in the SAM CLI build workflow for your JavaScript applications.

Developers using JavaScript and TypeScript can now use esbuild and SAM Accelerate to rapidly iterate on their code changes in the cloud, achieving the same levels of productivity they're used to when testing locally, while testing against a realistic application environment in the cloud. Support for esbuild includes features such as Minification, Tree Shaking, Source Maps, Loader, External and Main-Fields which can help simplify AWS Lambda development with JavaScript and TypeScript.
