Proof data consistency in a micro service landscape

Introduction Even if it doesn’t appeal to you, you might want to think about it when you work in a larger microservice landscape or have a serious big data platform…Proof data consistency in a microservice landscape. When we google this subject I already get 1.2 MLN results so there’s something going on here. To ensure data consistency several practices are available: Saga Pattern Reconciliation Event Log Orchestration vs. Choreography Single-Write With Events Change-First Event-First Consistency by Design Accepting Inconsistency But in this episode, we won’t go over these practices.

When it comes to developing software we use the adagio: You built it, You run it, You love it. Same should hold for all the -ilities or non-functional requirements. So, one should love their logging. One of the subjects that we did not really touch yet in our podcast is non-functionals. Today we take a closer look at logging. An aspect that typically fills some of the non-functionals or -ilities. Love your logs and Love the people after you. For the first time in the history of the bol.com Techlab…

One of the challenges in a (micro-)service landscape is to keep track of all capabilities in the services. Another is to keep track of the consumers of your service and the consumers beyond. Taking our IT landscape as an example: we work with over 120 teams on over 850 different applications varying from services, GUI’s, services, data builders and other types of applications. In an environment like ours, it’s crucial to understand what applications we have, what functionality they offer and who are working on them. In the past, the…

Web applications usually start small and loveable, but gradually become larger and larger as more people work on them and front-end technologies move on. If you’re not careful they can potentially end up as the one thing no-one wants to touch anymore and cause a lot of frustrations for agile teams and business innovators alike.

“My past year as a software engineer at bol.com has mostly been dedicated to breaking down one of the big monoliths within our software landscape into smaller services. To be more specific: I’ve been working in a team to extract the processes related to customer returns into a separate microservice.”

Applying “web scale” patterns in the bol.com back office Peter Paul van de Beek (IT Architect at bol.com) will show you in this session how we use “web scale” patterns to achieve scalability and flexibility in our back-office software. We will guide you through how we apply patterns like CQRS, event sourcing and micro services to solve puzzles in our back-office services. Interesting is that in our experience we don’t need these just to solve technical problems, they also help us solve some of our business problems! Sign up for…
