Application development is changing today due to the exponential growth of cloud and mobile technologies. While it has a minuscule name, microservices architecture revolutionizes how enterprises develop applications. Microservices are fine-grained services built with application programming interfaces (APIs) that support a specific application. Each microservice is independent and has a singular responsibility of delivering the exact functionality per its design. This article at DZone by Michael Bogan shares seven best practices for microservices architecture.
Embracing Microservices Architecture
Large applications that manage numerous distinct business tasks and technical operations from a single platform are the hallmarks of conventional software solutions. A monolithic design offers developers and operational teams a variety of benefits, including reduced costs for the tools they need to manage. Nonetheless, this infrastructure can quickly become unmanageable with regular upgrades and business expansion. An application approach known as a “microservices architecture” separates various parts and functionalities into distinct containers or clusters so they can run and scale independently. Many businesses are transforming their critical enterprise applications into microservices architecture to make them more agile and compatible.
Benefits of Microservices
Microservices is an improved version of software architecture that enables you to:
Automate, deploy faster, and scale-upImprove overall business uptimeMinimize impacts
Challenges of Microservices
A function extracted from a monolith application becomes an external API call in a microservices application. Therefore, it requires authentication and authorization for that outside microservice.Each time users access a new microservice, they must reauthenticate and reauthorize to access it.Microservice orchestration platforms play a crucial role in your scalability.
Best Practices for a Microservice Architecture
These best practices will assist you in building a robust, manageable, scalable, and secure network of interconnected microservices:
You must embrace the single responsibility principle to implement a microservices architecture. A single microservice will have a cascading effect on the rest of the system if it is overly dependent on it.To optimize costs, use separate file stores for each microservice to be more flexible. Find the provider or service that best suits the requirements of each microservice.A complete application may crash because of a single unreachable service causing a communication breakdown. Use the free and open-source Kong Gateway to ensure your communications are forwarded promptly and consistently to the appropriate microservices.
Furthermore, the author elaborates on compatibility, orchestrating of microservices, microservices security, and metrics and monitoring.
