Read the post Introducing Jupyter Scheduler, where Jason Weill introduces the project and how you can get started. <!--EndFragment--> <!--StartFragment--> <!--EndFragment--> ![image.png](https://dev-media.amazoncloud.cn/6d65eeecc1d34f9da6438ffc308f5d41_image.png "image.png") <!--StartFragment--> **aws-tf-prowler-fargate** [aws-tf-prowler-fargate](https://aws-oss.beachgeek.co.uk/2cv) is a Terraform module helps you assess your multi-account environment in AWS Organizations using the open source Prowler security assessment tool deployed on AWS Fargate. It assesses all accounts using a time-based schedule expression in Amazon CloudWatch, creates assessment reports in CSV format, and stores them in an Amazon Simple Storage Service (S3) bucket. <!--EndFragment--> <!--StartFragment--> <!--EndFragment--> ![image.png](https://dev-media.amazoncloud.cn/20e4735491aa4201ba8e4d647f64f533_image.png "image.png") <!--StartFragment--> **aws-iot-greengrass-v2-painless-installer** [aws-iot-greengrass-v2-painless-installer](https://aws-oss.beachgeek.co.uk/2cw) this solution allows installing Greengrass V2 on an edge gateway without requiring access to the AWS account where the device will connect. The User supervising the installation only needs to be able to authenticate with Amazon Cognito in order to initiate the installation process. No specific knowledge of the AWS Cloud nor Greengrass is necessary. The solution can be further customised for instance to federate user authentication to your enterprise identity management system (e.g. Active Directory). <!--EndFragment--> <!--EndFragment--> ![image.png](https://dev-media.amazoncloud.cn/7084f9747ce44328ae96c3fb854fa5c9_image.png "image.png") <!--StartFragment--> **anti-malware-scanning** [anti-malware-scanning](https://aws-oss.beachgeek.co.uk/2dp) Hardik Singh Behl has put together this reference solution together on how you can us the open source anti virus tool ClamAV, and use event driven capabilities of Amazon S3 to execute a Lambda function that scans the file for bad things. Very nice. <!--EndFragment--> <!--StartFragment--> <!--EndFragment--> ![image.png](https://dev-media.amazoncloud.cn/41a9b28a603b49a2acdc0cb534d359b1_image.png "image.png") <!--StartFragment--> **cdk-s3-upload-presignedurl-api** [cdk-s3-upload-presignedurl-api](https://aws-oss.beachgeek.co.uk/2dq) Jerome Van Der Linden has created this new AWS CDK construct to make your lives easier. If you want your users to be able to #upload a specific object to an Amazon S3 bucket, but you don't want them to have AWS security credentials or permissions, you can use pre-signed URLs. It's a common pattern but before Jerome created this construct, there was no IaC component that you could leverage directly. Great stuff Jerome. <!--EndFragment--> <!--StartFragment--> ### Demos, Samples, Solutions and Workshops **Lucene.Net-AWS-Lambda-EFS** [Lucene.Net-AWS-Lambda-EFS](https://aws-oss.beachgeek.co.uk/2dg) this project from Salman Sali enables you to implement a Serverless Search for .Net hosted on AWS Lambda with Amazon EFS Storage. <!--EndFragment--> <!--StartFragment--> **amazon-keyspaces-with-apache-kafka** [amazon-keyspaces-with-apache-kafka](https://aws-oss.beachgeek.co.uk/2d1) this repository contains hands on content how to build a data pipeline to ingest real time data using managed open-source compatible services such as Amazon Elastic Kubernetes Service (EKS), Amazon Managed Streaming for Apache Kafka (MSK), and Amazon Keyspaces (for Apache Cassandra). Apache Kafka and Cassandra share distributed core capabilities like high availability, scalability, and throughput that makes them a good solution for large scale processing applications like IoT data, user metadata, trade monitoring, and route optimisation. This data pipeline can consume a sample stream from Twitter API which streams 1% of all the tweets in realtime as a data source, parse the tweets, metadata, and publish the parsed data to a Kafka topic. Kafka works as a distributed queue as well as a buffer layer to transport messages. MSK Connect consumes these messages from Kafka topic and writes them to Amazon Keyspaces tables. <!--EndFragment--> <!--StartFragment--> The solution uses EKS to deploy containerised Twitter Event source application, the containerised application consumes, and a stream of tweets from Twitter API, parse the tweets (discards tweets that don’t have a hashtag), extract tweet metadata (created at, lang etc.), publishes these messages to Kafka topic twitter_input with desired fields using Kafka producer API. You will use the MSK Connect to ingest data from the twitter_input topic to Amazon Keyspaces. ![image.png](https://dev-media.amazoncloud.cn/dc26e30e8a254bfeaa1aea5c6e2146d4_image.png "image.png") <!--StartFragment--> **iot-analytics-athena-ddb** [iot-analytics-athena-ddb](https://aws-oss.beachgeek.co.uk/2cu) provides a solution for a reference architecture to analyse electricity data from smart meters, for maintenance purposes of a hypothetical Energy company, and for self-service analysis of customers, to understand how much electricity they consume. <!--EndFragment--> ![image.png](https://dev-media.amazoncloud.cn/f4cbd96f28b047c3bc6eb2beb5b94fd8_image.png "image.png") <!--StartFragment--> **amazon-sagemaker-clip-search** [amazon-sagemaker-clip-search](https://aws-oss.beachgeek.co.uk/2cz) this repository aims at building a machine learning (ML) powered search engine prototype to retrieve and recommend products based on text or image queries. This is a step-by-step guide on how to create SageMaker Models with Contrastive Language-Image Pre-Training (CLIP), use the models to encode images and text into embeddings, ingest embeddings into Amazon OpenSearch Service index, and query the index using OpenSearch Service k-nearest neighbors (KNN) functionality. <!--EndFragment--> <!--StartFragment--> <!--EndFragment--> ![image.png](https://dev-media.amazoncloud.cn/efbb1864a59e4c99bbbf20b2c8df0e56_image.png "image.png") <!--StartFragment--> **ack-rds-gitops-workshop** [ack-rds-gitops-workshop](https://aws-oss.beachgeek.co.uk/2d0) roll your sleeves up for this great workshop, where you will learn to deploy a continuous integration and delivery (CI/CD) workflow using GitOps and the AWS Controllers for Kubernetes (ACK) service controller for Amazon RDS on Amazon EKS to create and manage Amazon Aurora Serverless v2 databases effectively. GitOps relies on Git as the single source of truth for declaratively managing containerised infrastructure and application components. With Git at the centre of CI/CD pipelines, developers can automate and simplify application deployments and operations to Kubernetes. <!--EndFragment--> <!--StartFragment--> ### 2022 most popular posts As this is the last newsletter of 2022, I wanted to highlight the most viewed blog posts of 2022 just in case some of you missed these.

The growing adoption of artificial intelligence (AI) and machine learning (ML) in analytics has increased the need for processing data quickly and cost efficiently with GPUs. Nvidia RAPIDS Accelerator for Apache Spark helps customers leverage the benefit of GPU performance while saving infrastructure costs. With this release, EMR on EKS customer can use the RAPIDS accelerator by simply specifying the Spark-RAPIDS release label when calling EMR on EKS API. Until now, EMR on EKS customers had to create a custom image to use Nvidia RAPIDS Accelerator. This requires engineering and test effort. In addition, with every new Nvidia RAPIDS release, bug fixes or security updates, customers had to rebuild the custom image and go through the testing again. Starting with EMR 6.9, EMR on EKS is introducing a new Nvidia RAPIDS Accelerator for Spark image. Customers can use the same StartJobRun API to run their Spark jobs, and simply specify a new Spark-RAPIDS release label to leverage RAPIDS Accelerator on an EKS cluster with GPU supported instance type. <!--EndFragment--> <!--StartFragment--> **Prowler** [Prowler](https://aws-oss.beachgeek.co.uk/2ct), the handy cloud security tool, new version 3.0 has been fully rewritten in Python and can scan your AWS account in minutes across all regions and covering more than 250 checks for the most popular AWS services.

Last week was the announcement of the general availability of v2.0 Amplify Library for Android. Amplify Library for Android allows developers building apps for the Android platform to easily include features like authentication, storage, maps, and more. This version of the library has been re-written to improve Android developers’ experience when using Auth and Storage features. Also announced was the release of version 5 of the JavaScript library, which includes highly requested features for Web and React Native developers. This release also introduces a new Notifications channel, In-App Messaging, that developers can use to display contextual messages to their users based on their behaviour. The Amplify JavaScript library has also received improvements to reduce the overall bundle size and installation size. With this release, JavaScript developers can build media and file storage experiences with more granular pagination controls. Developers can now retrieve and filter nested models with Datastore lazy loading, such as retrieving all comments on a blog post. Amplify also provides UI components to make it easier to display In-App messages for React and React Native apps. Lastly, Apps that use GraphQL or PubSub subscriptions by default automatically re-connect when the user’s internet disconnects, providing a seamless experience for end users in poor connectivity scenarios. <!--EndFragment--> <!--StartFragment--> **MySQL and PostgreSQL** Amazon DevOps Guru for RDS now detects if your Amazon Aurora database is receiving a significantly larger number of SQL queries and if those queries are reading more data than usual.
