Businesses have been using microservices for years. They are among the most potent and popular architectural systems for building software today. The problem is that many businesses still don’t know much about them. This article explains what you need to know about microservices to use them effectively for your business.
What are Microservices?
Microservices are a type of software built using the distributed systems architecture pattern. In other words, it is made up of many small parts instead of being one big chunk like traditional software architecture. Microservices are typically used to build web applications because they provide an easier way to scale up or down depending on how much traffic your site gets at any given time (which makes them great if you want to do something like host an event)
The first step is to understand what microservices are. Essentially, microservices are an approach to appropriately modularizing an application. The idea is that you can break your app down into small modules that can be managed independently from each other, allowing developers to make changes in one module without worrying about the impact of those changes on other modules.
Microservices work best for large applications with lots of functionality. Since these types of apps tend to grow rapidly over time, using this architecture allows you to create and maintain a cleaner codebase that will allow it to continue growing over time.
Rather than building a massive piece of software with thousands of lines of code, microservices divide the application into separate parts. Each piece has its purpose and function while communicating and interacting with one another.
Prerequisites for getting into Microservices:
Understanding of distributed systems: Microservices require a strong knowledge of distributed systems. This means knowing how they work, what types are available and how they can benefit your application or business needs
- Good programming skills: You will need to have good programming skills to build a microservice architecture.
- Computer Science fundamentals (e.g. data structures, algorithms, problem-solving, OO Design)
- Object-Oriented Programming
- Cloud Computing Concepts
- Linux Shell Scripting
- Java programming language
- Knowing about HTTP, HTTP requests, and HTTP responses
There are a number of ways you can get microservices certification, they are:
1. Master Microservices – Udemy
This tutorial will take you on how to develop microservices using Spring Cloud. It goes into the microservice architectural style and demonstrates how to implement it using Spring technologies, notably Spring Cloud.
- This course provides a thorough introduction to the microservices architectural approach and hands-on experience with Spring Cloud activities.
- If you haven’t previously, you’ll receive a fast review of Spring Boot and Spring Data.
- Additionally, the course offers assignments that allow you to gain hands-on experience with Spring Cloud’s numerous components.
- Get hands-on training to orchestrate centralised microservices configuration.
2. Microservices Architecture – Pluralsight
This course will take you through the basics of microservices, from their design structure to technical constraints. The course takes you through the design principles before moving on to advanced subjects such as business domain-centricity, resilience, and observability.
- To complete the essential settings and installations, step-by-step instructions are provided.
- The instructor thoroughly reviews each concept and does it at a comfortable pace.
- Free trial period- You may access the classes for free for the first ten days after joining up.
3. Building Scalable Java Microservices – Coursera
This Specialisation will provide a comprehensive introduction to Spring Boot for building cloud-native Java microservices. You will learn how to work with relational databases in a distributed environment. You’ll also be introduced to Spring Cloud and its support for service discovery, configuration management, routing and resiliency patterns such as circuit breakers. By the end of this specialisation, you’ll be able to:
• Design solutions appropriate for running applications in a public cloud
• Create applications that incorporate an external data source
• Build a RESTful service using Spring Boot
• Apply principles of cloud computing to a microservice architecture
• Integrate multiple services into a single solution
4. Scalable Microservices – Udacity
In this Google-certified course, you will learn to build, test, and deploy a multi-container application using Docker and Kubernetes. You’ll also learn about the intricacies of developing highly scalable microservices and how to deploy them using continuous integration and delivery. You’ll learn how to build scalable and efficient containers, deploy them on a cluster managed by Kubernetes, and build your own CI/CD pipelines for these microservices.
- Create and start a Kubernetes cluster which features auto-scaling and self-healing capabilities.
- If you successfully pass all of the assignments with respective grades, you will get a certificate of completion.
- A variety of instances helps the reader obtain a better grasp of the concerns.
- Take the interactive tests to determine your level of familiarity with the content.
5. Introduction to Microservices Architecture – Learning Tree
Microservices architecture is a popular way to build distributed applications. It’s an agile development approach that enables you to build, test, deploy and scale individual components of an application that can be independently operated and maintained. In this course, you will learn the core concepts of microservices architecture and how to implement them in your organisation.
You will explore the benefits and drawbacks of a monolith versus a microservice architecture. You will discover how to define microservices and see how they are related to other architectural patterns such as SOA and API. Further, you will learn techniques for identifying new microservices and techniques for implementing them with Node.js and Docker.
- What microservices architecture is, how it works, and why it’s an attractive choice for building applications
- How to get started with microservices architecture and learn more about microservices
Microservices architecture is being adopted by many organisations as a means to accelerate development and deployment cycles, increase reliability and scalability, and reduce costs by enabling small autonomous teams to own the full lifecycle of services.
