Refactoring a monolith to microservices

The process of transforming a large, monolithic application into a more modular structure. Refactoring a monolith to microservices involves extracting independent modules or microservices that can be deployed and developed separately from the rest of the system.

The process of refactoring a monolith into microservices is like solving a Rubik's Cube — both require a strategic approach, understanding the dependencies between elements, and the ability to manage complex changes step by step. Each "turn" (change or division) must be carefully considered to achieve the goal: an efficient, well-organized system that operates smoothly and is easier to maintain and develop.

When do You need refactoring strategies?

When it becomes necessary to transform a monolith into a set of independent microservices, allowing development teams to work on separate components without interfering with each other.

When microservices need to be developed, deployed, and scaled independently, enabling more efficient management of human resources.

When you need more precise control over data access and protection, enhancing the overall security of the system.

When specific security measures need to be applied to individual components according to their unique requirements.

Advantages of refactoring a monolith for business

Increased efficiency in implementing changes

Refactoring monolith enables faster and more efficient changes to the system.

Developers can work on specific functionalities in isolation, reducing the time required for updates and new deployments.

As a result, the company can respond more quickly to market demands and customer expectations

A refactoring strategy is like the process of collecting gold coins through cost optimization. Just as well-thought-out financial actions lead to savings and resource growth, refactoring improves software efficiency, reduces technical debt, and enhances scalability, ultimately maximizing the value of the system and reducing long-term maintenance costs.

Reduced maintenance costs

Breaking down a monolith into smaller modules reduces system maintenance costs.

Modules can be updated and fixed independently, decreasing the time and resources needed to address issues.

This results in financial savings and more efficient use of IT resources.

Modular monoliths operate similarly to a molecular model, where smaller parts (modules or atoms) work together to form a larger, cohesive whole while maintaining their distinctiveness and autonomy. This approach enables the system to retain the benefits of a monolithic architecture, such as simplicity and performance, while offering modularity that allows for easier maintenance, scalability, and flexibility.

Improved scalability

A modular system structure enables more efficient scaling.

Businesses can flexibly allocate resources to specific parts of the system that require it, without the need to scale the entire system.

This optimizes infrastructure usage and allows for better adaptation to growing user demands.

Reduced risk of downtime and data loss

By refactoring a monolith, failures in one part of the system do not impact the entire system.

Isolating issues within specific modules reduces the risk of downtime and improves overall system stability.

This leads to greater user trust and minimizes the risk of data loss or operational downtime.

Refactoring strategies are like road signs in customer service — both aim to improve the system's functionality (whether an application or customer relations) through clear guidelines, eliminating unnecessary steps, and optimizing processes. Refactoring, much like road signs, simplifies and enhances performance, directly contributing to better customer service.

Improved customer service

Refactoring a monolith leads to improved system performance and stability, which in turn enhances customer service.

Fewer outages and faster implementation of fixes and new features mean that customers will have a more reliable and up-to-date product, increasing their satisfaction and loyalty.

Our project portfolio

The ability to organize work across multiple teams enables effective collaboration between different departments, better utilization of employee skills, and faster achievement of project goals.

This allows each team to focus on their specialties while contributing to the overall success of the organization.

In the context of the mySugr project, the refactoring strategy involved restructuring the application's codebase to enhance performance, maintainability, and scalability. By breaking down complex components and optimizing existing code, the team aimed to streamline the application, reduce technical debt, and improve overall efficiency.

Benefits of Refactoring for mySugr:

Reduced maintenance costs: Implementing the new version of Aurora led to a 50% reduction in application maintenance costs, resulting in significant financial savings.

Unified technology stack: mySugr became technologically consistent with the systems used by the Roche group, simplifying IT system management and integration.
