The document summarizes Betsson's journey from a monolithic architecture to a microservices architecture. It describes how the company started with a single monolith supporting one brand, then scaled the monolith by adding instances as more brands were acquired. This led to challenges with scalability, isolation, availability, and deployments. Betsson then moved to a SOA approach with larger services, but still faced issues. The company is now adopting microservices with bounded contexts for each functionality. This allows independent scaling of services using service discovery with Consul. Docker is used to isolate services and make them portable. The future involves using cluster schedulers to distribute services across servers.

What to expect from this talk A bit of history on where we came from in terms of architecture Geekery about microservices, service discovery, Docker and .NET Core I will not talk about Akka.NET I am not an Ops guy
The Past
One Brand, One System Bets10 The Monolith
We acquired more brands Bets10 The Monolith NordicBetBetsafe ??
Scaling the monolith A monolithic application puts all its functionality into a single process… …and scales by replicating the monolith on multiple servers -Martin Fowler, James Lewis
Scaling by Instance Instance 2 Brand C Instance 3 Brand D Instance 1 Brand A, B
Introducing SOA Instance 1 Instance 2 Instance 3 Customer Gaming Campaigns … Customer Gaming Campaigns … Customer Gaming Campaigns … Still pretty darn big services
Challenges?
Point to point communication Single Message Producer Single Message Consumer No Redundancy Doesn’t Scale
Shared Servers, Noisy Neighbours Instance Customer Gaming Campaigns …
Instance Single point of failure… Customer Gaming Campaigns …
…Same issue with deployment Instance Customer Gaming Campaigns … Down during deployment
Challenges! • Scalability, Elasticity • Isolation • Availability • Deployment
The Current
Adopting Microservices Customer Bounded Contexts Login Registration Customer Data
Scaling Microservices A microservice architecture puts each element of functionality into a separate service… …and scales by distributing these services across servers, replicating as needed -Martin Fowler, James Lewis
Scaling Microservices Where are you guys!? I’m over here!

Editor's Notes

  1. Founded in 1963 -strong history -we know what we’re doing Strong growth of approx 10% annually and strong EBIT margins at around 25%. Q2 was a disappointment, but we have taken action and Q3 has started well. Despite Q2 revenue was less than we hoped for, we have a strong underlying activity with an all time high of active players during Q2. Betsson is listed at Nasdaq Stockholm large cap. Betsson’s board believes in return to shareholders and the direct yield is 5-5.5%. We employ close to 1800 people across Europe. Our largest site, where I am based, is Malta with some 800 employees
