von Legacy in die Cloud

At birkle IT, we adhere to industry standards and implement them!

In the constantly evolving technology landscape, companies are constantly faced with the challenge of keeping their software infrastructure up to date. There is a particular focus on legacy to cloud. One of the biggest changes is the migration from legacy desktop applications to modern, cloud-based solutions. This transition is not just a technical upgrade, but an opportunity for a fresh start that can redefine the way a company works.

birkle It has already successfully completed many such transformation projects.

The legacy challenge

Monolithically developed legacy software too often becomes a bottleneck for innovation.

While most systems were robust in their day, they tend to be inflexible, difficult to scale and expensive to maintain. As companies grow and technology advances, the limitations of legacy systems are becoming increasingly apparent. Migrating these applications to the cloud offers numerous benefits, including improved scalability, higher performance and lower operating costs. Cloud migration is always a challenge. It is also important to choose the right cloud computing provider.

Case study 1: Migration of logistics services from legacy to cloud application

Our client offers a full supply chain service for logistics companies. At the beginning of the project, many core processes were running on a monolithic desktop application. The problem was that the application had limitations in flexibility of e.g. pricing and delivery but also problems with scalability.

The decision to migrate the application from a legacy desktop application to the cloud was quickly made. However, this change required a complete rewrite of the application. Based on our experience, we recommended switching to a microservice architecture. We also developed the implementation of a new business logic in order to be able to respond more flexibly to customer requests in the future.

Our approach: Component-based migration approach

  • Identification: The first step was to identify and categorize the various components of the application. This included separating the components of the user interface, business logic and data storage functionalities.

  • Decoupling: Each component is decoupled from the monolithic application so that the development team can understand and isolate dependencies and components

  • Rewrite: Individual components were rewritten as microservices. This modular approach enabled parallel development and testing, which significantly accelerated the migration process.

  • Deployment: The microservices are deployed in a Kubernetes cluster, with cloud load balancing ensuring optimal resource utilization and high availability.

Scalability of the migration is a huge advantage

Realized advantages

  • Scalability: Thanks to Kubernetes‘ microservice architecture and orchestration capabilities, the application can now be easily scaled to handle higher loads.

  • Flexible: Individual microservices can be updated or replaced without affecting the entire system, resulting in faster innovation cycles.

  • Cost efficiency: Cloud resources are used more efficiently, which reduces operating costs.

Case study 2: Asset management and maintenance

A SaaS application for asset management and maintenance was struggling to cope with growth from taking on new customers and implementing additional functionality, as their legacy software was experiencing various scaling issues. Migrating from a legacy on-premise application to a cloud-native application laid the foundation for further growth.

Our approach: Component-based migration approach

  • Evaluation: critical components and interactions of applications are identified

  • Modularization: Functions such as inventory tracking, maintenance planning and spare parts management are modularized and rewritten as microservices

  • Integration: The microservices are integrated into a Kubernetes environment with cloud load balancing to ensure smooth performance during peak shopping hours.

Verbesserte Leistung

Realisierte Vorteile

  • Skalierbarkeit: Das System kann skaliert werden. Kunden aus der Industrie und dem Gesundheitswesen können so unterbrechungsfreie Dienste bereitstellen.

  • Verbesserte Leistung: Das neue System bietet schnellere Antwortzeiten und eine bessere Leistung, was das Kundenerlebnis steigert.

  • Operative Agilität: Das Unternehmen kann sich schnell an Marktveränderungen anpassen und neue Funktionen oder Dienste ohne größere Unterbrechungen einführen.

  • Verlässlichkeit: Cloud Load Balancing und Kubernetes Clustering sorgen für hohe Verfügbarkeit und reduzieren Ausfallzeiten.

The strength of component-based migration of legacy software

Component-based migration offers a structured approach to modernizing legacy software. By breaking down a monolithic application into individual components, companies can manage the complexity of the migration process more effectively. This approach enables:

  • Parallel development. Different teams can work on separate components simultaneously, speeding up the overall migration schedule.
  • No big bang! Smaller, incremental changes reduce the risk of errors and make it easier to identify and fix problems.
  • No downtime! Organizations can gradually transition to a cloud-native environment and continuously improve and refine their systems.

Conclusion

Migrating legacy software to the cloud is a transformative journey that offers significant benefits. By adopting a component-based migration strategy and leveraging modern technologies such as microservices and Kubernetes, organizations can achieve unprecedented levels of scalability, flexibility and efficiency.
