The advent of microservices technology in cloud computing revolutionized the development of enterprise applications by leveraging modularity, scalability, and agility. This shift allowed organizations to respond more effectively to changing business requirements and utilize cloud infrastructure’s full potential for improved performance, reliability, and innovation. Today, the undisputed industry leader is Amazon and its AWS services. Therefore, businesses need to become familiar with the specifics, components, and advantages of microservices in AWS to make timely decisions regarding the company’s IT management and further digitalization.

Characteristics of Microservices Technology

Microservices represent a modern development approach, featuring small, independent services dedicated to specific business capabilities. Developed using diverse technologies and programming languages, these services seamlessly communicate through well-defined APIs. Executed by small, cross-functional teams, each microservice is created, deployed, and maintained independently.

In contrast to monolithic applications, where a single failure can disrupt the entire system, microservices ensure fault isolation, preventing a failure in one component from affecting the whole application. This architectural shift offers scalability and flexibility, allowing each service to be independently scaled, updated, and restarted, promoting agility in development.

Microservices decompose large applications into smaller, independently deployable services, each with its database, fostering decentralized data management. This approach enables efficient resource utilization and faster development cycles. In comparison, monolithic applications are developed and deployed as a single, tightly integrated unit, making it challenging to scale or update individual components.

Technological foundations of microservices usage include:

• containerization utilizing tools like Docker for independent service operation;
• orchestration tools such as Kubernetes that manage deployment and scaling;
• API Gateways for communication between microservices through well-defined interfaces.

While microservices architecture is not exclusive to AWS, Amazon stands as a leader in the industry, providing a robust suite of services supporting microservices development. Let’s look at AWS microservices architecture specificity closer.

Monolithic architecture vs microservices

Microservices Architecture in AWS

On the AWS platform, microservices can be implemented in various ways, such as serverless computing with AWS Lambda, containerized solutions with Amazon ECS and Amazon EKS, or running managed Kubernetes clusters. AWS offers tools for efficient data management, user-friendly interfaces through services like AWS API Gateway, and seamless deployment with AWS CloudFormation.

A standard architecture structure for microservices in AWS typically involves the following components:

• User Interface (UI)
  The front-end component is responsible for user interaction and presentation and is hosted on a content delivery network (CDN) like AWS CloudFront.
• Compute implementation
  The core logic and functionality of microservices are implemented through compute services. It can include serverless computing with AWS Lambda, containerized solutions with Amazon ECS or Amazon EKS, or a combination based on the specific needs of the microservice.
• Datastore
  Microservices often require data storage for persistence and retrieval. AWS offers various database services, such as DynamoDB for NoSQL, Aurora for relational databases, or RDS for managed database services.
• Communication
  Application Programming Interfaces keep connections between microservices and are managed through AWS API Gateway.
• Caching
  In-memory caching services like Amazon ElastiCache enhance performance by storing frequently accessed data.
• Orchestration
  Container orchestration services manage containerized applications’ deployment, scaling, and operation. Amazon ECS or Amazon EKS provides orchestration capabilities for containerized microservices.
• Infrastructure management
  Tools like AWS CloudFormation help define, deploy, and manage the overall infrastructure as code.
