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.

Sitting Considered Deadly: Introduce Movement in Our Workdays
Prolonged sitting wreaks havoc on our bodies and our minds. A first step to introduce more movement throughout your workday is to organize a sit-stand workstation, claimed Marek Stój in his talk Sitting Considered Deadly at Codemotion Amsterdam 2019. He suggested alternating between the two and trying out various ways in which one can sit or stand.

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.

Reflecting on Top-Down or Bottom-Up System Design: Vaughn Vernon at MicroXchg Berlin
Should software design be driven by a top-down or bottom-up approach? Vaughn Vernon asked the question in his presentation at MicroXchg Berlin, where he discussed different approaches to software design, actor model, reactive domain-driven design and the importance of an emergent architecture.

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.

Migrating a Retail Monolith to Microservices: Sebastian Gauder at MicroXchg Berlin
In his presentation at MicroXchg in Berlin, Sebastian Gauder described how he and his teams migrated an existing food retail monolith at REWE, a large German company, into several business domains with 270 microservices, while increasing the number of teams from two up to 48. He also discussed the different design goals and rules they setup to make this possible.

Discovering Culture through Artifacts: QCon London Q&A
Behavior and values are two critical components to organizational culture; values denote what the organization believes in, and behaviors are rooted in those values, argued Mike McGarr, engineering leader at Slack. At QCon London 2019 he spoke about improving your understanding of an organization’s culture, the key components of culture, and what to look for in order to learn about the culture.

Mashreq Bank’s Lean Agile Journey
After having seen and evidenced the tangible benefit of lean at Mashreq Bank, agile was seen as a natural progression, an evolutionary step. Agile and lean are well-linked; you still need to identify waste, and remove non-value add activities so you can spend more time doing what the customer needs, argued Steve Snowdon. Together with Ed Capaldi he spoke about Mashreq Bank’s Lean Agile Journey.

Agile in Higher Education: Experiences from The Open University
Universities need to embrace an agile and product mindset, as they are grappling with hypothesis-driven development of new kinds of products and services of which they understand very little, for users whose behaviours and needs they little understand, said Matthew Moran. He presented applying the agile mindset, principles and practices for online course development at Aginext 2019.
