After completing, Certhippo's Microservice training, you will be able to:

·         Understand and differentiate between various Microservices Architectural styles

·         Apply Microservices Architecture principles

·         Know how to make the appropriate Microservice Architecture decision

·         Develop and test a Microservice

·         Know what technologies can be used to enable Microservices with an example

Microservices Architecture, or simply Microservices, is a unique method of developing software systems as a suite of independently deployable, small, modular services in which each service runs a unique process and communicates through a well-defined, lightweight mechanism to serve a business goal.  Thanks to its scalability, this architectural method is considered ideal when you have to enable support for a range of platforms and devices—spanning across the web, mobile, Internet of Things, and so on. Because of its flexibility, you can also use this method when you’re not sure what kind of devices you’ll need to support in an increasingly Cloud-based future.

There are no prerequisites for attending this Microservice course. Understanding of programming languages such as Java, basic understanding and familiarity with Spring Boot framework and building  Java applications would be useful to execute Case Study and Project.

·         Application Architects

·         Software Architects

·         Application Developers

·         Developer working on Web, Cloud, Mobile, and other social technologies

·         A system with 4GB RAM and i3 or above processor

·         Java and Spring Boot Framework

For your practical work, we will help you set-up the Java environment on your system along with Eclipse IDE and the Spring Boot framework. This will be a local access for you. The detailed step by step installation guides will be present in your LMS which will help you to install and set-up Java, Spring Boot, and Eclipse IDE.

A fictional Company named GOODs, which is an e-commerce company, provides online purchasing services and operates its business using a traditional Java EE-based Web Application called Customer Order Service. Although the application has been serving the business well, Company GOODs, started struggling with responding to new business.

Requirements: 

The current customer order service application is not designed to enable changes in business domain and is not open for applying recent technologies for accelerating innovation with the current monolithic architecture. Company GOODs wants to transform the customer order service application to embrace and better handle changes in both business and technical perspectives and has a list of major business Requirements:

·         The new system must be evolutionary, meaning it must be flexible for changes.

·         No down time is allowed in moving traffic from the current system to the newly built system.

·         The new application must be able to scale on demand, or automatically, based on the payload sent to the system, so that it can react to dynamic shopping behavior patterns.

·         The new system must be open for leveraging emerging technologies to embrace innovation.

In this In-Class Project, you will develop a virtual wallet for an e-commerce marketplace.

The Project is divided into two phases – 

  1. Build a simple marketplace with a few products having a shopping cart and an e-wallet.

  2. Refactor the marketplace to perform e-wallet integration by adding a circuit-breaker Microservice
