What Comes after Microservices? Multi-Runtime Microservices with Bilgin Ibryam at QCon London
Bilgin Ibryam talked at QCon London about the evolution of distributed systems on Kubernetes and the future architecture trends. Ibryam said that the next trend would be to decouple infrastructure concerns from microservices. Ibryam calls this multi-runtime microservices, a service with business logic along with a sidecar in charge of state management, networking, binding, and lifecycle.

Balancing Coupling in Distributed Systems: Vladik Khononov at DDD Europe
We have been told that coupling is bad, so we decouple everything and break everything apart into tiny services that can be changed independently. But by following this reasoning we often end up with a distributed mess, Vladik Khononov noted in his presentation at the recent DDD Europe 2020 conference in Amsterdam. Instead of fighting coupling, he proposes that we use it as a design tool.

How Serverless Impacts Design: Gojko Adzic at DDD Europe
Serverless architectures are becoming mainstream and can reduce both time to market and operational costs. But to benefit from them, applications must be designed around the constraints of this architecture style. At the recent DDD Europe 2020 conference, Gojko Adzic discussed his experience using serverless and how DDD and a serverless architecture will impact the design of an application.

Event Sourcing Done Right - Experience from the Trenches: Dennis Doomen at DDD Europe
Event sourcing is just a tool; it’s not a top level architecture style and should not be used everywhere, Dennis Doomen pointed out in his presentation on the Event Sourcing day at the DDD Europe 2020 Conference in Amsterdam where he shared some of the practices he has found useful when applying event sourcing to a problem.

How Twitter Improves Resource Usage with a Deterministic Load Balancing Algorithm
Twitter recently shared the details of why their RPC framework Finagle implements a client-side load balancing using a deterministic aperture algorithm for their microservices architecture. Twitter ran different experiments but confirmed that with a deterministic approach, requests are better distributed, connections count reduces drastically, and they even need less infrastructure.

Change Data Capture Tool Debezium 1.0 Final Released
The open source change data capture (CDC) tool Debezium 1.0 Final was recently released with an event format clean-up, increased test coverage of databases, and 96 issues addressed. In a blog post Gunnar Morling describes Debezium's basic concepts and some common use cases, and details about both the current release and what to expect in future releases.

Decision Strategies for a Micro Frontends Architecture
Micro frontends is an architectural style for frontend applications based on the concepts of microservices. Luca Mezzalira believes this is a style that will change the future of these applications. There are some challenges though and architectural decisions that must be made, and he has therefore created a decisions process for embracing a micro frontends architecture.

Dynein – an Asynchronous Background Job Service from Airbnb
At Airbnb, they move time consuming, resource intensive tasks over to asynchronous background jobs to improve scalability. The job scheduling system has become a very important component and they have therefore built Dynein, a distributed delayed job queueing service and scheduler. In a blog post, Andy Fang from Airbnb describes the background and challenges in designing and building the service.

Experience Running Spotify’s Event Delivery System in the Cloud
Event delivery is a key component at Spotify; the events contain important data about users, actions they take, and operational logs. After running the event delivery system in the cloud for 2 ½ years, Bartosz Janota and Robert Stephenson have written a blog post discussing what they have achieved and how they have been able to evolve and simplify the system by moving up the stack in the cloud.

Mind Your State for Your State of Mind: Pat Helland at QCon SF
The features of different types of data storage should be considered when selecting how data is stored in a system. Is always reading correct data, or low latency, most important? In his keynote at this year’s QCon San Francisco, Pat Helland described trends in storage and computing, durable and session state semantics, and other aspects of storage like transactions, identity and immutability.

Jay Kreps: Events, Event Streams and Their Importance in a Digital Business
Organizations are moving more and more processes into software, Jay Kreps notes in a blog post, and adds that in an accompanying change businesses are increasingly defined in software – the core processes are specified and executed in software. To support this transition, he believes we have to move away from traditional databases into working with the concepts of events and events streams.

Gutenberg – a Publish-Subscribe Service for Datasets Created by Netflix
To propagate datasets from a single producer to multiple consumers, Netflix has created Gutenberg, a service using a publish-subscribe technique to propagate versioned datasets between their microservices. In a blog post, Ammar Khaku, senior software engineer at Netflix, describes an overview of the design as well and some use cases for Gutenberg.
