Starting from a historical perspective, Woods described how software systems have evolved in the past three decades. In the 80’s we were all using monolithic architectures, which evolved into distributed monoliths in the next decade...

Mature Microservices and How to Operate Them: QCon London Q&A
Microservices is an architectural approach to keep systems decoupled for releasing many changes a day, said Sarah Wells in her keynote at QCon London 2019. To build resilient and maintainable systems you need things like load balancing across healthy nodes, backoff and retry, and persistence or fanning out of requests via queues. The best way to know whether your system is resilient is to test it.

Amplifying Sources of Resilience: John Allspaw at QCon London
At QCon London John Allspaw presented “Amplifying Sources of Resilience: What Research Says”. Key takeaways from the talk included: that resilience is something a system does, not what a system has; creating and sustaining “adaptive capacity” within an organisation is resilient action; and learning about how people cope with surprise is the path to finding sources of resilience.

In a Serverless World, We Still Need State
Today there is a large push in enterprise architecture towards serverless architecture. Jonas Bonér argues that although he strongly believes in the serverless movement, the programming model should not focus only on stateless functions. We must also have a focus on state, allowing us to benefit from the advantages of serverless while building distributed general-purpose applications.

Build a Monolith before Going for Microservices: Jan de Vries at MicroXchg Berlin
Most developers don’t work at global large-scale companies like Netflix. Most developers work in much smaller companies with maybe up to 50 – 80 developers, Jan de Vries noted in his presentation at MicroXchg Berlin, where he argued that a properly built monolith in many cases is superior to a microservices based architecture. With a well-built monolith, it will also be easy to pull services out.

Creating Events from Databases Using Change Data Capture: Gunnar Morling at MicroXchg Berlin
When you store data in a database, you often also want to put the same data in a cache and a search engine. The challenge is how to keep all data in sync without distributed transactions and dual writes. One way is to use a change data capture (CDC) tool that captures all changes made. In a presentation at MicroXchg Berlin, Gunnar Morling described Debezium, an implementation of CDC using Kafka.
