Microservice Architecture without Using Spring Cloud

 Spring Cloud is a popular open-source framework that provides a set of tools and libraries to build and deploy microservices-based applications. It offers a wide range of features such as service discovery, configuration management, load balancing, and circuit breaking, among others. However, it is possible to implement a similar architecture to Spring Cloud without using the framework itself. Here are some tips on how to achieve this:

  1. Service discovery: Service discovery is a critical component of microservices architecture. It allows services to register themselves and discover other services in the system. You can implement service discovery without Spring Cloud by using a third-party service registry such as Consul, Eureka, or Zookeeper. These service registries provide APIs that allow services to register themselves and discover other services.

  2. Configuration management: Configuration management is another important feature provided by Spring Cloud. It allows you to centralize configuration management and change configuration at runtime. You can achieve similar functionality without Spring Cloud by using a configuration server such as Apache Zookeeper, etcd, or HashiCorp Consul.

  3. Load balancing: Load balancing is an essential feature of microservices architecture. It ensures that requests are distributed evenly among all instances of a service. You can implement load balancing without Spring Cloud by using a load balancer such as Nginx or HAProxy.

  4. Circuit breaking: Circuit breaking is a design pattern used to prevent cascading failures in a microservices architecture. It allows a service to fail gracefully instead of bringing down the entire system. You can implement circuit breaking without Spring Cloud by using a circuit breaker library such as Netflix Hystrix or Resilience4j.

  5. API gateway: An API gateway is a component that sits between the client and the services. It provides a single entry point to the system and can perform functions such as authentication, rate limiting, and request routing. You can implement an API gateway without Spring Cloud by using a proxy server such as Nginx or HAProxy.

In conclusion, while Spring Cloud provides a comprehensive set of tools and libraries to build and deploy microservices-based applications, it is possible to achieve similar functionality without using the framework itself. By using third-party tools and libraries, you can build a robust microservices architecture that is scalable, fault-tolerant, and easy to manage.

Server-Side Pagination with React-Table and Spring Boot JPA with H2 Database

Pagination is a common technique used to split large amounts of data into smaller, more manageable chunks. With server-side pagination, data is retrieved from the server in smaller batches, reducing the amount of data transferred over the network and improving application performance. React-Table provides a wide range of built-in features such as sorting, filtering, pagination, row selection, and column resizing. These features can be easily configured and customized to fit specific requirements. For example, you can customize the sorting behavior to handle multiple sorting criteria, or you can add custom filters to the table to handle complex data filtering scenarios. Additionally, React-Table provides a flexible API that allows developers to extend its functionality with custom hooks, plugins, and components. This means that you can easily add custom functionality to the table, such as exporting data to CSV or integrating with external data sources. In terms of styl...
