MicroServices Architecture - Spring Boot and Netflix Infrastructure

MicroServices Architecture

In the realm of modern software development, Microservices architecture is the favored choice over Monolithic architecture, as it offers enterprises improved agility, scalability, resilience, and flexibility. Enterprises can enjoy the benefits of more frequent delivery of new features and updates, cost savings due to better resource utilization, and the ability to scale specific services independently of others.

5 Business Benefits of Microservices

Faster time-to-market

  • With Microservices architecture, enterprises can deliver new features and updates faster and more frequently. This can help businesses stay ahead of the competition and meet changing customer demands quickly.

Improved Agility & Adaptability

  • Microservices architecture allows for faster and easier development, testing, and deployment of services. This enables enterprises to respond quickly to market changes and adapt to new business requirements.

Meet Demand without Overspending

  • Microservices architecture enables enterprises to scale specific services independently of others, providing greater flexibility and efficiency in resource utilization. This can help enterprises meet increasing demand without overspending on resources.

Improved Fault Tolerance

  • Microservices architecture provides improved fault tolerance, allowing enterprises to quickly identify and resolve issues, minimizing downtime and improving the overall customer experience.

Increased Productivity

  •  By enabling teams to work independently and simultaneously on different services, Microservices architecture enhances collaboration, productivity, and innovation. This results in cost savings over time, as well as reduced downtime.
  • This field is for validation purposes and should be left unchanged.

  • Faster development: iBEAM can help modernize legacy applications in just eight weeks. This can help businesses save time and money on development projects.
  • Streamlining Operations & Customer Experiences: iBEAM can also streamline operations and customer experiences. This can help businesses improve efficiency and productivity.
  • Greater agility, scalability, and efficiency: The document says that iBEAM can also help businesses achieve greater agility, scalability, and efficiency. This can help businesses adapt to changing market conditions and grow their operations.

Microservices Architecture via Netflix Components

We have used the Netflix components to accomplish the above microservices architecture patterns.

Major Components of Netflix

Netflix Eureka – Service Discovery Server

Netflix Microservices


Netflix Eureka allows microservices to register themselves at runtime as they appear in the system landscape.

Netflix Ribbon – Dynamic Routing & Load Balancer

Netflix Ribbon

Netflix Ribbon can be used by service consumers to lookup services at runtime. Ribbon uses the information available in Eureka to locate appropriate service instances. If more than one instance is found, Ribbon will apply load balancing to spread the requests over the available instances. The ribbon does not run as a separate service but instead as an embedded component in each service consumer.


Netflix Zuul – Edge Server

Netflix Zuul - Edge Server


Zuul is (of course) our gatekeeper to the outside world, not allowing any unauthorized external requests to pass through. Zulu also provides a well-known entry point to the microservices in the system landscape. Using dynamically allocated ports is convenient to avoid port conflicts and to minimize administration but it makes it of course harder for any given service consumer. Zuul uses Ribbon to look up available services and routes the external request to an appropriate service instance


Spring Boot & Spring Cloud Netflix OSS – MicroService Architecture

Spring Boot - Microservice Architechture

Microservices with Spring Boot

Spring Boot is a brand new framework from the team at Pivotal, designed to simplify the bootstrapping and development of a new spring application. The framework takes an opinionated approach to configuration, freeing developers from the need to define the boilerplate configuration.

Spring Cloud Netflix

Spring Cloud Netflix provides Netflix OSS integrations for spring boot apps through autoconfiguration and binding to the spring environment and other spring programming models. With a few simple annotations, we can quickly enable and configure common patterns inside the application and build large distributed systems with Netflix components. There are a lot of features available with spring cloud Netflix. Here, we have listed some of the common features we have implemented with microservices with spring boot and Netflix,


Why Netflix uses Spring Boot

01. Simplified Configuration

Spring Boot provides a fast and easy way to set up and configure a microservices-based system, reducing the time required for development and deployment

02. Production-Ready Features

Spring Boot includes a number of features that are useful in production environments, such as embedded servers, health check endpoints, and security features.

03. Improved Resilience

The design of Spring Boot helps to promote a resilient architecture, with features such as circuit breakers and automatic retries helping to minimize the impact of service failures.

04. Large Community

Spring Boot has a large and active community of developers who contribute to the platform, helping to ensure that it continues to evolve and meet the needs of its users.

05. Integration with other Spring projects

Spring Boot integrates well with other projects in the Spring ecosystem, such as Spring Cloud, making it easier to build a complete microservices-based system.

06. Testing Support

Spring Boot provides a number of testing features, making it easier to test microservices and ensure that they are working as expected.

5 Key Components of Microservice Architecture

API Gateway

An API Gateway is a central entry point that enables clients to access the services in the microservices architecture. It provides a unified interface for the clients to interact with the different services. An API Gateway can handle tasks such as authentication, authorization, rate limiting, and API documentation. It also provides security, monitoring, and load balancing capabilities.

Service Registry

A service registry is a central repository that maintains a list of available services in the microservices architecture. It provides the location and status of each service, making it easier for other services to discover and communicate with each other. A service registry can use different protocols and standards, such as ZooKeeper, Consul, or Eureka.

Load Balancer

A load balancer is a component that distributes incoming requests across multiple instances of a service. It ensures that the load is evenly distributed across the instances, and that each instance is fully utilized. Load balancing can be performed at different levels, such as the network layer, the application layer, or the API Gateway layer.

Configuration Server

A configuration server is a central repository that stores the configuration settings for each service in the microservices architecture. It provides a central location for managing the configuration settings, making it easier to update and manage the configuration settings. A configuration server can use different formats and protocols, such as YAML, JSON, or Spring Cloud Config.

Service Discovery

Service discovery is the process of locating available services in the microservices architecture. It involves querying the service registry to find the location and status of each service. This enables services to discover and communicate with each other dynamically. Service discovery can be performed using different techniques, such as client-side discovery or server-side discovery.
