The performance of legacy applications in the Cloud environment is often suboptimal due to inherent dependencies between logical components or modules and/or data access methods. There is a need to refactor or rewrite applications to leverage the different Cloud services and newer development tools like MVC frameworks, Server-less architecture, etc. Front-ends need to be more responsive to preserve user experience and back-end systems have to handle functionally independent services at scale (Micro-services).
Tek Solutions has been engaged in developing and supporting applications using an innovative methodology and technology-based approach. Our microservices-based approach provides the agency with the flexibility and rapidity to build scalable functions without the long wait and large budgets.
What answers do we provide before recommending a transition to a microservices architecture?
- The business value in moving from a monolithic application architecture to a microservices-based architecture
- Technical considerations such as microservices communications techniques and scenarios, including testing and transition strategies
- Common mistakes to avoid and best practices for the process
- The role of containers and service mesh in microservices
Traditional Approaches to Designing Microservices
As organizations recognize the benefits of a microservices architecture approach, they face the question “How do we divide up our monolithic applications into more manageable pieces?” Most of our customers answer this question with either a top- down approach or a bottom-up technical approach
The top-down approach involves a functional decomposition of the application, beginning at the business level. The architect separates out functionalities based either on domain (domain-driven design) or on business capability.
The bottom-up approach is purely technical, using the availability of development resources as the basis for microservice designation. The architect may look at service functionalities and bundle them together to create a single microservice. Or the architect may divide up larger applications by technology, such as Java or Node.js, and create microservices based on those groupings.
Each approach offers a distinct set of advantages — top-down is more easily understood by non-technical decision makers, and bottom-up makes more efficient use of existing development resources. However, each encompasses its share of challenges as well.
Tek Solutions's Blended Approach
When we work with clients to design their microservices architecture, we recommend a blended approach that leverages the greatest benefits of each traditional strategy:
- Begin with a domain model or functional decomposition, which gives you the candidates for your services.
- Optimize your services inventory using a technical approach, either separating or folding functions together from the operational perspective, to determine how you’re going to manage those services.
