October 12th - Instalment # 39
Week No.39 - The 39 Steps is a pretty famous film, a spy thriller if you are into those types of films and I recently found out that the name came from a location not too far from me. I am pleased to say that episode 39 of this newsletter is equally thrilling, combining the usual mix of new open source projects (including one so fresh, it is still warm to the touch), blog posts, case studies and events for you to check out. An old friend, JMeter, is also covered this week under the quick updates section so if you are using JMeter, don’t miss that. Finally, make sure you check out the Diagram Maker post, which seemed to grab a lot of attention last week, as well as my favourite topic, AWS Graviton2.
Last week it was great to speak with Arpit Mohan, CTO and co founder of Appsmith, an amazing open source project that provides very rich low/no code tooling to enable you to quickly create applications within your organisation. Will try and get it published for the next episode.

Using multiple queues and instance types in AWS ParallelCluster 2.9 Nathan Stornetta and Anh Tran share some of the new features available in the latest release of the open source project, AWS ParallelCluster. AWS ParallelCluster has made it simple for high performance computing (HPC) customers to set up easy-to-use environments with compute, storage, job scheduling, and networking in the cloud in one cohesive package. In version 2.9, two new features covered in this post are around how this new release support multiple job queues and multiple instance types.
- Multiple job queues - a common setup inside many traditional HPC environments is to use multiple queues that have varying levels of priority and different compute resources associated with them. This helps ensure that the most urgent workloads have prioritised access to any resources they require, whereas other workloads can wait longer or run on resources with lower costs.
- Multiple instance types - allows you to separate workflows into either multiple queues or multiple instance types within the same queue and select distinct compute resources optimised for the price/performance or memory/CPU of each step in our workflow or for different workload types.
These new features enable customers to have more complex and varied HPC workflows that can be used to optimise costs and help with things like prioritisation.
Integrating Jenkins with AWS CodeArtifact to publish and consume Python artifacts Matt Ulinski shows you how you can manage/publish your software packages and then consume these within your Jenkins projects. The walkthrough takes you through the package/publish and consume/deploy process, ending up with the sample application deployed on AWS Fargate. You will learn everything you need to set up your own environment, and to make it even easier, Matt provides you with a CloudFormation template that will deploy the solution.
Migrating CloudFormation templates to the AWS Cloud Development Kit from Adam Ruka writes how using a new feature of AWS CDK, you can now import your existing CloudFormation templates into your CDK stack. Once loaded, you can then modify objects defined in your templates directly within your CDK code, or reference existing template resources when creating new CDK constructs. The CfnInclude class is what makes this happen. Adam covers some use cases and where you might find this useful and there are some things you need to watch out for. So, now that you have an idea, check out the blog post for the deep dive with examples.

Automating Index State Management for Amazon ES Satya Vajrapu’s post show you how to use policies that have been introduced with Index State Management (ISM) to implement a sample policy to automate routine index management tasks and apply them to indexes and index patterns. Maintaining multiple indexes for diverse data workloads, typically means the setting up of custom solutions to manage the indexes’ lifecycle which can quickly become tedious as the indexes grow and result in housekeeping overheads. ISM allows you to automate those tasks via policies and you can use a variety of criteria when defining those policies. Take a peek for more details on what those might be.

Amazon ElastiCache for Redis now supports Redis 6. This release brings several new and important features to Amazon ElastiCache for Redis.
- Managed Role-Based Access Control – Amazon ElastiCache for Redis 6 now provides you with the ability to create and manage users and user groups that can be used to set up Role-Based Access Control (RBAC) for Redis commands. You can now simplify your architecture while maintaining security boundaries by having several applications use the same Redis cluster without being able to access each other’s data. You can also take advantage of granular access control and authorization to create administration and read-only user groups. Amazon ElastiCache enhances the new Access Control Lists (ACL) introduced in open source Redis 6 to provide a managed RBAC experience, making it easy to set up access control across several Amazon ElastiCache for Redis clusters.
- Client-Side Caching - Amazon ElastiCache for Redis 6 comes with server-side enhancements to deliver efficient client-side caching to further improve your application performance. Redis clusters now support client-side caching by tracking client requests and sending invalidation messages for data stored on the client. In addition, you can also take advantage of a broadcast mode that allows clients to subscribe to a set of notifications from Redis clusters.
- Significant Operational Improvements - This release also includes several enhancements that improve application availability and reliability. Specifically, Amazon ElastiCache has improved replication under low memory conditions, especially for workloads with medium/large sized keys, by reducing latency and the time it takes to perform snapshots. Open source Redis enhancements include improvements to expiry algorithm for faster eviction of expired keys and various bug fixes.
Distributed Load Testing on AWS helps you easily simulate thousands of users connecting to your application so that you can better understand your application performance under load. The solution launches and configures containers on AWS Fargate to generate a specified number of transactions per second without having to provision servers.
This update adds support for JMeter test scripts. JMeter is a popular open source application for testing functional behavior and performance, and this update allows customers to use JMeter scripts to test the robustness of their applications. This update also introduces AWS Step Functions to reduce solution complexity.
