Microservices

Hi there,Welcome to my "Microservices | Spring Cloud Microservice with Rest API" course.

Microservices & Spring boot | Learn Spring Cloud Microservice & Spring Framework with Rest API, ElasticSearch & RabbitMQ

Microservices is a growing standard in cloud based software design, used by several companies today. Microservices, or microservices architecture, is an approach to software and website development that breaks down a large project into multiple, independent chunks of code. Each code, called a microservice, gets developed to perform a specific function within the overall software package. Microservices, designed by separate teams, run independently and combine with other microservices to fulfill a larger goal. For example, an e-commerce site includes different functions to manage inventory, product catalogs, customer data, and billing information.

Microservices architecture is a software design approach where an application is divided into a collection of small, loosely coupled, and independently deployable services. Each of these services, known as microservices, focuses on a specific business capability or function. These microservices communicate with each other through well-defined APIs, allowing them to work in harmony to deliver a complete application experience.

With a microservices approach to site development, they would get separately developed and tested before being combined to create the final website. Microservices get compared to “monolithic” software architecture, in which the entire software package gets developed as a single unit.

Microservices enables developers to break apart applications into a series of decoupled cloud services, containerizing each individual piece. Through this software design method, engineers can implement necessary software changes more swiftly than with standard system architecture. The Spring Framework is a comprehensive framework for Java development that provides infrastructure support, enterprise-level features, and promotes the use of best practices in software design and architecture. It was created by Rod Johnson and was first released in 2003. The primary goal of the Spring Framework is to simplify the development of complex enterprise applications by providing a cohesive, modular, and extensible framework.

Welcome to a transformative journey into Microservices Architecture, a paradigm shift that redefines how we build and deploy applications. Microservices Architecture, often hailed as the cornerstone of modern software development, offers a set of principles and practices that break down monolithic applications into smaller, independently deployable services.

In today's rapidly evolving technology landscape, where agility, scalability, and rapid development are paramount, traditional monolithic software architectures have started to show their limitations. Enter microservices architecture, a modern approach to building software applications that has gained immense popularity for its ability to address the challenges posed by monolithic systems and empower organizations to thrive in the digital age.

Let's explore the advantages and considerations of Microservices First Advantages:

Scalability and Flexibility

Microservices enable horizontal scalability, allowing you to scale individual services based on demand. This flexibility ensures efficient resource utilization and responsiveness.

Modularity and Independence

Services operate independently, promoting modularity. Developers can work on and deploy services independently, fostering parallel development and reducing dependencies.

Technological Diversity

Embrace a polyglot approach, choosing the right technology stack for each service. This flexibility enables optimal solutions for diverse business requirements.

Improved Fault Isolation

Isolate failures to specific services, preventing a single service failure from affecting the entire application. This enhances system resilience and fault tolerance.

Frequently asked questions

What are microservices?

Microservices, or microservices architecture, is an approach to software and website development that breaks down a large project into multiple, independent chunks of code. Each code, called a microservice, gets developed to perform a specific function within the overall software package. Microservices, designed by separate teams, run independently and combine with other microservices to fulfill a larger goal. For example, an e-commerce site includes different functions to manage inventory, product catalogs, customer data, and billing information. With a microservices approach to site development, they would get separately developed and tested before being combined to create the final website. Microservices get compared to “monolithic” software architecture, in which the entire software package gets developed as a single unit.

What are the benefits of a microservices architecture?

While a microservices architecture takes more initial planning than a monolithic architecture, it offers distinct advantages in large-scale systems. A microservices architecture breaks down complex software projects into smaller components. Because each microservice gets developed separately, the architecture facilitates faster development times as they get designed in parallel rather than in sequence. Since each microservice operates independently, the engineer can update one microservice without the changes causing problems with other microservices. That saves a lot of testing and debugging time in the overall software project. Finally, a microservices architecture helps development teams understand the general code easily, making the software easier to maintain and deploy.

What careers use microservices?

Microservices are used primarily by software developers, especially front-end developers, back-end developers, and full-stack developers. DevOps engineers also get familiar with microservices—as tech companies implementing Agile and DevOps teams will more likely take advantage of microservices benefits. While a microservices architecture could theoretically get used for any software, web developers commonly create complex websites and web-based applications with it.

What are some common tools to implement microservices?

Microservices architecture developers use various Java-based languages, libraries, and frameworks like React, Node.js, Spring Cloud, and Spring Boot since microservices help with software and application development. In addition, team communication remains critical when implementing microservices—the reason why development teams use tools such as Apache Kafka and RabbitMQ. Finally, containerization tools such as Kubernetes and Docker help developers manage the function, packaging, and collaboration of individual microservices.

What is Spring Boot and why it is used?

Java Spring Boot (Spring Boot) is a tool that makes developing web application and microservices with Spring Framework faster and easier through three core capabilities: Autoconfiguration. An opinionated approach to configuration. The ability to create standalone applications.

What is PostgreSQL and why it is used?

It is a highly stable database management system, backed by more than 20 years of community development which has contributed to its high levels of resilience, integrity, and correctness. PostgreSQL is used as the primary data store or data warehouse for many web, mobile, geospatial, and analytics applications.

Why PostgreSQL is more popular?

PostgreSQL is chosen by companies because it offers data types that MySQL does not, as well as many other features that are not offered in MySQL. Generally, however, MySQL is typically recommended for web-based/online or mapping functions, whereas PostgreSQL is recommended for large analytical processes.
