Microservices

Adapt to change faster and build to scale

Why microservices matter

You need to move faster. Your users want more. Building agility into both your systems and processes is the only way to future-proof your business. Creating a microservices architecture allows individual services to be deployed and scaled independently, giving teams the autonomy they need to deliver more at speed. We collaborate closely with all stakeholders and empower development teams with agile tools, making sure that every microservices success becomes a catalyst for continued transformation.

Get Started

Microservices deliver macro value

Microservices is not a buzz term—it’s a surefire strategy for getting your systems up to speed and setting you up for future growth. More than an IT solution, microservices is a business value-driver that breeds:

Agility

Your development pipeline shrinks, and teams have the autonomy to bring new features to market with speed

Resilience

Infrastructure agnostic and independent, microservices are much easier to update and maintain

Scale

You can scale individual services separately to meet the specific and ever-changing needs of your users and your business

From monolith to microservices

Our right-sized approach

Almost all microservices stories start with a monolith that got too big: the application is slow, the backlog has grown, time to production is way too long, and the infrastructure has been pushed beyond its limits. The impetus for moving to microservices is clear—but where do you start? Our right-sized approach to microservices involves finding a starting point that makes the most sense for your business—regardless of the actual service size. We’ve honed a manageable process for migrating those features from the monolith seamlessly, which serves as the blueprint for building a more flexible and resilient architecture:

1. Define the business boundaries

We dive into your application, interview users and product owners, and create visual maps of service boundaries that will guide the process forward.

2. Identify the first microservice

We choose a right-sized service to start with by considering key factors such as feature-planning, team abilities, performance issues, and complexity.

3. Create the backlog

Through a detailed dependency analysis we extract the core code of the bounded contexts to tease the monolith system apart and assign deeper research tasks and development tickets.

4. Develop and test

We propose an architecture based on the needs of the service, while simultaneously developing a regression test plan to ensure feature parity once the work is complete.

5. Deploy the microservice

Whenever possible we develop microservices as features that can be switched on and off in production, ensuring rollback is always an option.

6. Iterate and scale

We utilize success patterns and lessons learned to plan for and grow a robust microservices architecture.

No microservices project is equal. That’s why we take the time to really dig into your system and get to know your teams in order to develop a strategy that works with and for your business.

Making eMoney more agile with microservices

Moving to a microservices architecture benefits the business, long term. Take it from eMoney, which needed to rethink its application architecture in order to make good on its mission of empowering users. We successfully decoupled the first service from the existing monolith, while simultaneously empowering development teams to be more agile. The microservices blueprint we created became a springboard for scaling the system, setting eMoney up for continued growth in the fintech space.
