Our traditional fintech clients have large monoliths of applications, often silos of financial, customer or marketing data. They face an uphill battle to compete:
They all desire to move to a smarter and more agile environment but the challenge seems too high until they talk to 42flows.tech and we share our tools and experience. After all our motto is “Future, Fintech, Fast”?
Monoliths Start becoming spaghetti fast
Break Your Monolith into Microservices
Microservices is a common architecture approach where the application is divided into small, autonomous services that work together. It is based on on a lean, agile business principle where we:
Standalone services allow for scalability and agility
Is Microservices something new? While the term might still sound fresh, the approach itself evolved from best practices combining techniques that were around for quite some time: small autonomous teams, systems at scale, domain-driven design, continuous delivery, on-demand virtualization, infrastructure automation, and others.
Small and Autonomous
Business groups and software code become unmanageable as they grow too large. Like trying to walk a dozen dogs, with each new release it becomes harder and harder to track, coordinate where the changes are and the overhead just becomes too big and full of relations.
To prevent this from happening we adopt the single responsibility principle. While in monolithic systems we try to achieve this by code classes, abstractions and modules. Microservices provide a clearer separation of responsibility into independent services focused on a specific task and connected through APIs. Microservice is an autonomous entity that can be deployed on a platform as a service (PAAS) and can be changed and deployed independently of other microservices.
It’s hard to tell how small the services should be in terms of code lines but as Jon Eaves stated in his article it is something that can be rewritten by the team in two weeks.
Benefits
Technology Choice Versatility, Freedom to Innovate
With microservices we can choose a suitable technology for each service separately, ensuring that it is the perfect fit for a specific case. As the IT industry changes rapidly and new technologies emerge every day it comes really handy as we are not bound to a strict technology stack for the whole of our enterprise. If some part of it requires an update in terms of performance or data storage capabilities or any other kind of enhancement, we may switch the technology stack of that service to the one that fits our needs best without a need to rewrite the whole project.
Resilience
In Monolithic based architecture if one part of the system fails it usually means that the whole system stops working. Microservice based systems are designed in a way that if one component fails, the failure doesn’t cascade. You can isolate a problem and fix it separately.
Scaling
If one or two small parts of our service require more resources , we don’t need to scale everything all together. We choose the services that need a boost and invest in them directly, which is cost efficient. We invest in winners.?

Deployment
Each minor change to the monolithic application requires a large deployment. Large regression test and large risk risk. Due to the risk involved such deploys happen infrequently, which results in an even higher risk.
With microservices, services are being deployed independently. If the problem occurs, it can be located, isolated and fixed faster. Has less side effects and ensures a faster time to market for the new functionality.
Big Teams - Big Coordination Overhead
Big teams and big codebases are always a problem. We work best in small focused units with clear contracts with other teams.
Versatility and Reusability
In a fast-paced world end-users might be interested in your service today and want to lean towards something else the day after. The fintech world we love is filled buzzing with new features:
Microservices architecture allows you to reuse the separated services in your other projects.
42Flows Smart Teams with Smart Tool to SpeedUp Integrations
From our experience, integration tasks are the most critical, and that is the place where most problems appears. To move from legacy to rapid innovation fast and effectively we use Node-Red. An open source, low code, nodejs integration tool that allows us to:
Node-Red can be a great helper here. It’s a perfect match for integrations with out of the box:
And many more ..?
Practice shows that businesses want to change the business logic frequently to try out new approaches and tune the current ones in search for perfection. Node-Red allows us to make these changes fast, increasing time to market. Within Nod-Red you can focus on implementing business rules instead of writing large amounts of code.
