Dr. Werner Vogels’ keynote is usually the most anticipated at AWS re:Invent conventions. It’s no surprise he delivers what can be considered the closing keynote. He took a break from Now Go Build – Season 3 production to visit with customers in Las Vegas at the AWS re:Invent 2022 conference. Dr. Vogels and his team have perfected the art of keynote delivery with a cinematic intro, some background education, guest speakers to support the talk’s theme, and always an inspiring set of new service introductions.
This year’s theme was “Managing Complexity by observing and imitating natural patterns in our systems”. This was a very entertaining and educational as well as inspirational keynote. There was something for everyone. Worth watching when you have an hour and a half to invest.
The closing statement can bring the entire keynote into focus:
“I hope that you can all agree that we can learn from something like looking around us and observing the greatest system in existence, the universe itself. The universe itself is extremely agile; It is extremely fault tolerant as well and resilient and robust.
We should learn from the principles that we see in nature and the world around us when we start building our computer systems. I hope this talk has inspired you to build bigger, better bolder systems much faster.”
Let’s break this down as it happened.
The cinematic intro: This was a “The Matrix Spoof” where a world that is completely ordered and synchronized one to one exists. You realize very quickly that the concepts of throughput and latency become essential to be able and do anything. High throughput, low latency, loosely coupled and events processing are to be pursued in our systems if they are to continue delivering results despite a failure or malfunction. He says, “Synchronous is a simplification, an abstraction, a convenience to write our programs, and finally an illusion” to be avoided in our systems design. The world is asynchronous and event driven. We should imitate that as much as possible in our systems.
The background education:
“Synchrony implies tightly coupled systems.” and the initial Amazon S3 Design principles used in 2006 still apply to this day in order to avoid such a situation.
Amazon S3 Design Principles:
- Local responsibility
- Decompose into small well understood building blocks.
- Controlled concurrency
- Failure Tolerance
- Controlled Parallelism
Embracing asynchrony leads to loosely coupled systems and embracing workflows enable us to build applications from loosely coupled systems.
The patterns for workflows have a general guiding set of principles which can be summarized as:
- Error Handling,
- Based on data,
- Concurrent iterative
Loosely coupled systems implement:
- Fewer dependencies
- Failure isolation
- Evolvable architectures
The natural sequence to this best practice is the journey from a monolithic application to evolve to service oriented architecture to a micro-service architecture that uses shared services via (IaaS).
According to Gall’s Law: “All complex Systems that work evolved from simpler systems that worked.”
“It’s evolve or perish when it comes to systems design and the best way to build systems that can evolve is to focus on event driven architectures. Event driven architectures enable global scale. Event-driven architectures help development teams move faster. The world is built in patterns.”
Patterns in Event Driven Architectures include:
- Change Data Capture
- Asynchronous coupling
- Self-healing replicators.
Finally, you can also take a look at the following Cloud Academy courses and have a hands-on experience with:
- Decoupling Architecture Within AWS by Stuart Scott [38 m]
- Connecting Application Data Using Amazon EventBridge by Will Meadows [16 m]
- Processing File Uploads Asynchronously with Amazon EventBridge by Andrew Burchill [1h 30m]
The Service Introductions:
1) Step Functions Distributed Map (Generally available)
A Serverless Solution for Large-Scale Parallel Data Processing
“Step Function’s map state executes the same processing steps for multiple entries in a dataset. The existing map state is limited to 40 parallel iterations at a time. This limit makes it challenging to scale data processing workloads to process thousands of items (or even more) in parallel. In order to achieve higher parallel processing prior to today, you had to implement complex workarounds to the existing map state component.”
“The new distributed map state allows you to write Step Functions to coordinate large-scale parallel workloads within your serverless applications. You can now iterate over millions of objects such as logs, images, or CSV files stored in Amazon Simple Storage Service (Amazon S3). The new distributed map state can launch up to ten thousand parallel workflows to process data. You can process data by composing any service API supported by Step Functions, but typically, you will invoke Lambda functions to process the data with code written in your favorite programming language.”
“This new capability is optimized to work with S3. I can configure the bucket and prefix where my data is stored directly from the distributed map configuration. The distributed map stops reading after 100 million items and supports JSON or CSV files of up to 10GB.”
“When processing large files, think about downstream service capabilities. Let’s take Lambda again as an example. Each input—a file on S3, for example—must fit within the Lambda function execution environment in terms of temporary storage and memory. To make it easier to handle large files, Lambda Powertools for Python introduced a new streaming feature to fetch, transform, and process S3 objects with minimal memory footprint. This allows Lambda functions to handle files larger than the size of their execution environment. To learn more about this new capability, check the Lambda Powertools documentation.” (per the AWS launch blog.)
2) AWS Application Composer (Preview)
Visually design and build serverless applications quickly. Visual canvas makes composing serverless applications easier. Rapidly generate ready to deploy infrastructure as code (IaC) that follows best practices. Maintain a model of your architecture that’s easy to share and build with team members.
The call to action by Dr. Vogels: “I urge you to start with AWS application Composer to make it easy for you to get started with building these applications.”
“AWS Application Composer is a visual builder that makes it easier for developers to design an application architecture by dragging, grouping, and connecting AWS services in a visual canvas. Developers can start a new architecture from scratch, or they can import an existing AWS CloudFormation or AWS Serverless Application Model (SAM) template, including those generated by AWS Application Composer. The AWS Application Composer experience is focused around common serverless services like AWS Lambda, AWS Step Functions, and Amazon EventBridge, but it can be used to compose any AWS service supported by AWS CloudFormation resources. Developers can export infrastructure as code (IaC) to incorporate into their existing processes, such as local testing with AWS SAM Command Line Interface (CLI), peer review through version control, or deployment through CloudFormation and continuous integration and delivery (CI/CD) pipelines.”

3) Amazon EventBridge Pipes (Generally available)
Connects event producers and consumers in seconds. Build advanced integrations in minutes with enhanced security, reliability and scalability out of the box.
“So basically this is pipes on steroids because it’s not just easily composed, It also has the ability to manipulate the events that are flowing through your pipe.” Dr. Werner Vogels
Write less code – Build fully managed integrations quickly with an easy-to-use interface that connects event producers with consumers.
Save costs with filtering and built-in integrations – Lower compute and usage costs by using event filters and built-in integrations – only process and pay for events that you need.
Source events in real-time – Deliver events to over 14 AWS services with EventBridge Pipes seamlessly polling for new events.
Reduce operational load – Reliably connect services without worrying about scalability, security, patching, and provisioning your infrastructure.
