**Feedback**

Please let me know how we can improve this newsletter 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: John Russell, Beny Ibrani, Eilon Harel, Eugene Yahubovich, Richard Case, John Russell, Faizal Khan, Ashish Bhatia, Jagadeesh Chitikesi, Benson Kwong, Stanley Chukwuemeke, Baruch Assif Osoveskiy, and Kehinde Otubamowo

### 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

**enclaver**

[enclaver](https://aws-oss.beachgeek.co.uk/27k) is a new open source toolkit created to enable easy adoption of software enclaves (such as what is provided by AWS Nitro Enclaves), for new and existing backend software. Make sure you check the project documentation out which outlines in more detail some of the aspects of enclaves.

![architecture of enclaver](https://raw.githubusercontent.com/edgebitio/enclaver/37cf1140d56930ff980643a9a1ebdd07a2afe567/docs/img/diagram-enclaver-components.svg)

Eugene Yahubovich, the project founder has also put together a very nice blog post that dives deeper into use cases and how to get started. Go read, [Introducing Enclaver: an open-source tool for building, testing and running code within secure enclaves](https://aws-oss.beachgeek.co.uk/27n). This weeks project of the week.

**s3crets_scanner**

[s3crets_scanner](https://aws-oss.beachgeek.co.uk/27l) is an open source tool from Eilon Harel that is designed to provide a complementary layer for the Amazon S3 Security Best Practices by proactively hunting secrets in public S3 buckets. It can be executed as scheduled task or run On-Demand.

![demo of s3crets_scaner](https://github.com/Eilonh/s3crets_scanner/blob/main/DOCS/scanner_gif.gif?raw=true)

Eilon Harel has also put together a blog post diving deeper into this, in the post [Hunting After Secrets Accidentally Uploaded To Public S3 Buckets](https://aws-oss.beachgeek.co.uk/27m)

![secret scanner workflow](https://miro.medium.com/max/1400/0*Sw-YWjtV0rRFecr4)

**sandbox-accounts-for-events**

[sandbox-accounts-for-events](https://aws-oss.beachgeek.co.uk/27q) "Sandbox Accounts for Events" allows to provide multiple, temporary AWS accounts to a number of authenticated users simultaneously via a browser-based GUI. It uses the concept of "leases" to create temporary access tickets and allows to define expiration periods as well as maximum budget spend per leased AWS account. Check out the docs for some example uses cases where you might find a tool like this useful, as well as understanding more how this works under the hood.

![sandbox accounts for events](https://github.com/awslabs/sandbox-accounts-for-events/blob/main/docs/images/table-leases.png?raw=true)

**frontend-discovery**

[frontend-discovery](https://aws-oss.beachgeek.co.uk/27r) The aim of this project is to define and drive adoption of a frontend discovery pattern, with a primary focus on client-side rendered (CSR), server-side rendered (SSR) and edge-side rendered (ESR) micro-frontends. The frontend discovery pattern improves the development experience when developing, testing, and delivering micro-frontends by making use of a shareable configuration describing the entry point of micro-frontends, as well as additional metadata that can be used to deploy in every environment safely.

Check out the readme to find out more about the motives behind the project, and dive into it with an example.

### Demos, Samples, Solutions and Workshops

**mapper-for-fhir**

[mapper-for-fhir](https://aws-oss.beachgeek.co.uk/27p) FHIR is a standard for health care data exchange, and this repo provides assets that allow for the automated deployment of an HL7v2, leveraging native AWS services. The repo provides a CDK application that simplifies deployment.

**cf-sam-openapi-file-organization-demo**

[cf-sam-openapi-file-organization-demo](https://aws-oss.beachgeek.co.uk/27w) The project is the API back-end for a widget tracking website. Widget tracking is simplistic - widgets have only a unique name and a colour descriptor for properties. If you want to explore how to approach API design, then this is a good repo to explore.

![architecture of apis](https://github.com/aws-samples/cf-sam-openapi-file-organization-demo/blob/main/img/Architecture-Diagram.png?raw=true)

**sam-accelerate-nested-stacks-demo**

[sam-accelerate-nested-stacks-demo](https://aws-oss.beachgeek.co.uk/27v) This repository shows how to use CloudFormation nested stacks with AWS SAM Accelerate. Nested stacks are stacks created as part of other stacks. In this demo repo, there are four separate stacks that make up the entire solution. AWS SAM manages all four as CloudFormation nested stacks. During development, we show how to use SAM Accelerate to quickly update resources, shortening the development loop.

![architecture of SAM accelerate nested stack demo](https://github.com/aws-samples/sam-accelerate-nested-stacks-demo/blob/main/orders.jpeg?raw=true)

**decoupling-microservices-lambda-amazonmq-rabbitmq**

[decoupling-microservices-lambda-amazonmq-rabbitmq](https://aws-oss.beachgeek.co.uk/27u) This project is a solution architecture that demonstrates decoupling micro services with Amazon MQ for RabbitMQ and AWS Lambda. A decoupled application architecture allows each component to perform its tasks independently and a change in one service shouldn't require a change in the other services.

![architecture for amazonmq rabbitmq solution](https://github.com/aws-samples/decoupling-microservices-lambda-amazonmq-rabbitmq/blob/main/diagrams/mq_decoupled_apps.png?raw=true)

**how-to-write-more-correct-software-workshop**

[how-to-write-more-correct-software-workshop](https://aws-oss.beachgeek.co.uk/27t) so last week I featured duvet, a tool to help you codify and automate validation of your software against honouring RFC specs. This repo contains a workshop that walks you through a practical example of that, but also features dafny, a programming language that formally verifies your implementation matches your specification. I have this on my weekend to do list.

### AWS and Community blog posts

**Kubernetes**

Benson Kwong has been busy putting this blog post together, [Multi-cluster management for Kubernetes with Cluster API and Argo CD](https://aws-oss.beachgeek.co.uk/27z) where he introduces what Cluster API is and explained why you can use this useful tool for managing multiple Kubernetes clusters instead of struggling with different APIs and tool sets to maintain them. He also covers how you can also integrate ArgoCD to add that sprinkle of continuous delivery with Git as your source of truth. [hands on]

### Quick updates

**PHP**

AWS App Runner now supports PHP 8.1, Go 1.18, .Net 6, and Ruby 3.1 managed runtimes for building and running web applications and APIs. These runtimes enable you to leverage the App Runner “build from source” capability to build and deploy directly from your source code repository without needing to learn the internals of building and managing your own container images.

Starting today, you can build and run your services based on PHP 8.1, Go 1.18, .Net 6, and Ruby 3.1 directly from your source code on App Runner. All these new managed runtimes in App Runner are active long-term support (LTS) major versions.

**Apache Kafka**

Amazon Managed Streaming for Apache Kafka (MSK) now offers Tiered storage that brings a virtually unlimited and low-cost storage tier. Tiered Storage lets you store and process data using the same Kafka APIs and clients , while saving your storage costs by 50% or more over existing MSK storage options . Tiered Storage makes it easy and cost-effective when you need a longer safety buffer to handle unexpected processing delays or build new stream processing applications. You can now scale your compute and storage independently, simplifying operations.

Amazon MSK Connect also now supports Private DNS hostnames for enhanced security. With Private DNS hostname support in MSK Connect, you can configure connectors to reference public or private domain names. Connectors will use the DNS servers configured in your VPC’s DHCP option set to resolve domain names. You can now use MSK Connect to privately connect with databases, data warehouses and other resources in your VPC to comply with your security needs.

**Amazon EMR**

Amazon EMR 6.8 has seen a number of updates that you should be aware of.

*PrestoDB and Trino*

With PrestoDB and Trino on EMR 6.8, users benefit from a configuration setting, called the strict mode that prevents cost overruns due to long running queries.Customers have told us that poorly written SQL queries can sometimes run for long times, and consume resources from other business critical workloads. To help administrators take action on such queries, we are introducing strict mode setting that allows warning or rejecting certain types of queries. Examples include queries without predicates on partitioned columns that result in large table scans, or queries that involve cross join between large tables, and/or queries that sort large number of rows without limit. You can set up strict mode configuration during cluster creation and also override the setting using session properties. You can apply strict mode checks for select, insert, create table as select and explain analyse query types.

We are also excited to announce that Amazon EMR PrestoDB and Trino has added a new features to handle spot interruptions that helps run your queries cost effectively and reliably. Spot Instances in Amazon EMR allows you to run big data workloads on spare Amazon EC2 capacity at a reduced cost compared to On-Demand instances. However, Amazon EC2 can interrupt spot instances with a two-minute notification. PrestoDB/Trino queries fail when spot nodes are terminated. This has meant that customers were unable to run such workloads on spot instances and take advantage of lower costs. In EMR 6.7, we added a new capability to PrestoDB/Trino engine to detect spot interruptions and determine if the existing queries can complete within two minutes on those nodes. If the queries cannot finish, we fail quickly and retry the queries on different nodes. Amazon EMR PrestoDB/Trino engine also does not schedule new queries on spot nodes that are about to be reclaimed. With these two new features, you will get best of both worlds - improved resiliency with PrestoDB/Trino engine on Amazon EMR, and running queries economically on spot nodes.

*Hive*

Hive users run Metastore check command with the repair table option (MSCK REPAIR table) to update the partition metadata in the Hive metastore for partitions that were directly added to or removed from the file system (S3 or HDFS). When run, MSCK repair command must make a file system call to check if the partition exists for each partition. This step could take a long time if the table has thousands of partitions. In EMR 6.5, we introduced an optimisation to MSCK repair command in Hive to reduce the number of S3 file system calls when fetching partitions . This feature improves performance of MSCK command (~15-20x on 10k+ partitions) due to reduced number of file system calls especially when working on tables with large number of partitions. Previously, you had to enable this feature by explicitly setting a flag. Starting with Amazon EMR 6.8, we further reduced the number of S3 filesystem calls to make MSCK repair run faster and enabled this feature by default.

In addition to MSCK repair table optimisation, we also like to share that Amazon EMR Hive users can now use Parquet modular encryption to encrypt and authenticate sensitive information in Parquet files. It is a challenging task to protect the privacy and integrity of sensitive data at scale while keeping the Parquet functionality intact. Data protection solutions such as encrypting files or storage layer are currently used to encrypt Parquet files, however, they could lead to performance degradation. With Parquet modular encryption, you can not only enable granular access control but also preserve the Parquet optimisations such as columnar projection, predicate pushdown, encoding and compression. Using Parquet modular encryption, Amazon EMR Hive users can protect both Parquet data and metadata, use different encryption keys for different columns, and perform partial encryption of only sensitive columns. It also allows clients to check integrity of the data retrieved while keeping all Parquet optimisations. 

*Apache Flink*

Amazon EMR includes Apache Flink 1.15.1. This feature is available on EMR on EC2.
Apache Flink is an open source framework and engine for processing data streams. Apache Flink 1.15.1 on EMR 6.8 includes 62 bug fixes, vulnerability fixes, and minor improvements over Flink 1.15.0. Key features include:

Watermark alignment (Beta) across data sources : Event-time processing in Flink depends on special timestamped elements, called watermarks, that are inserted into the stream either by the data sources or by a watermark generator. A watermark with a timestamp t can be understood as an assertion that all events with timestamps < t have already arrived. Watermark alignment is useful when processing sources with different velocity of events e.g. when one source is idle or one source emits records relatively faster than others, you can enable watermark alignment for each source separately. Flink aligns watermarks by pausing the highest velocity source and continuing to read records from other sources until the watermarks are aligned.
SQL version upgrade : Introducing JSON plans which are JSON functions that make it easier to import and export structured data in SQL. Today, version upgrades can alter the topology of SQL queries which can introduce snapshot incompatibility across versions. This makes upgrading Flink versions challenging. With this feature, both the Table API and SQL will provide a way to compile and execute a plan ensuring the same topology for SQL queries throughout different versions, making it more reliable to upgrade to future versions. Users who want to give it a try can create a JSON plan that can then be used to restore a Flink job based on the old operator structure.

*Apache Hudi and Apache Iceberg*

Amazon EMR release 6.8 now supports Apache Hudi 0.11.1 and Apache Iceberg 0.14.0. You can use these frameworks on Amazon EMR on EC2, and Amazon EMR on EKS as well as on Amazon EMR Serverless.

Apache Hudi 0.11.1 on Amazon EMR 6.8 includes support for Spark 3.3.0, adds Multi-Modal Index support and Data Skipping with Metadata Table that allows adding bloom filter and column stats indexes to tables which can significantly improve query performance, adds an Async Indexer service which allows users to create different kinds of indices (e.g., files, bloom filters, and column stats) in the metadata table without blocking ingestion, includes Spark SQL improvements adding support for update or delete records in Hudi tables using non-primary-key fields and Time travel query via timestamp as of syntax, includes Flink integration improvements with support for both Flink 1.13.x and 1.14.x and support for complex data types such as Map and Array etc. In addition, Hudi 0.11.1 includes bug fixes over Hudi 0.11.0 available in Amazon EMR release 6.7. 

Apache Iceberg 0.14.0 on Amazon EMR 6.8 includes support for Spark 3.3.0, adds Merge-on-read support for MERGE and UPDATE statements, adds support to rewrite partitions using Z-order that allows to re-organize partitions to be efficient with query predicates on multiple columns and also to keep similar data together, includes several performance improvements for scan planning in Spark queries, add support for row group skipping using Parquet bloom filters, etc.

**AWS ParallelCluster**

AWS ParallelCluster 3.3 is now generally available and introduces a new feature for compute resource optimisation. With this new feature, you can map a compute resource to a list of Amazon EC2 instance types with an allocation strategy to optimize compute capacity for your HPC jobs. Other features include updates that support dynamically mounting shared storage, Slurm accounting, and Amazon EC2 on demand capacity reservations (ODCR).

Check out the announcement for more details, [AWS ParallelCluster 3.3: multiple instance type allocation and other top requested features](https://aws-oss.beachgeek.co.uk/27h)

Matt Vaughn has also published a blog post, [Support for Instance Allocation Flexibility in AWS ParallelCluster 3.3](https://aws-oss.beachgeek.co.uk/27i), where he explains in detail how a new feature that was also announced called “multiple instance type allocation” in ParallelCluster 3.3.0. This feature enables you to specify multiple instance types to use when scaling up the compute resources for a Slurm job queue. Your HPC workloads will have more paths forward to get access to the EC2 capacity they need, helping you to get more computing done.
