Hands-On Enterprise Java Microservices with Eclipse MicroProfile

Introduction to Eclipse MicroProfile

Eclipse MicroProfile is a set of specifications for microservices written in the Java language. It is a project that is community-driven with many implementations in the market. The project, first announced in June 2016, continues to develop a set of common Application Programming Interfaces (APIs) for implementing Java microservices suitable for modern application development techniques, architectures, and environments. In this chapter, you will learn about the origin and importance of Eclipse MicroProfile.

The following topics will be covered in this chapter:

  • Enterprise Java microservices
  • Forces that fuel the digital economy and the need for multi-speed IT
  • Introducing Eclipse MicroProfile
  • MicroProfile value proposition

Enterprise Java microservices

Application development no longer consists of using a single high-level programming language that runs on your favorite operating system. Nowadays, there are a myriad of languages, specifications, frameworks, proprietary and open source software and tools, underlying deployment infrastructures, and development methodologies that programmers need to learn to develop modern applications. Development at IT organizations has become polyglot, that is, multiple programming languages are used depending on the needs of specific projects. In this age of the cloud, containers, microservices, reactive programming, 12-factor applications, serverless, MINI services, polyglot environments, and so on, developers now have the option to choose the right tool for their task, making them more effective and productive.

With the recent move of Java EE to the Eclipse...

Forces that fuel the digital economy

The terms digital economy and digital transformation describe the convergence of four different forces that are changing the needs of businesses: mobile, cloud, IoT, and open source:

Before the internet, organizations required brick-and-mortar stores or phone lines to conduct their businesses. The advent and accessibility of the internet created a critical category-formation time opportunity for organizations. Businesses started to use the internet mainly as a storefront or display in order to drive people to their brick-and-mortar stores. It was also used for advertising purposes.

Soon after this, businesses began adding the ability to purchase things online, and companies, such as Amazon, realized that they could capitalize on the economies-of-scale, product aggregation, consolidation, recommendation, and pricing optimization that an online...

Introducing Eclipse MicroProfile

Java EE has been an extremely successful platform. The Java Community Process (JCP) has been the steward of over 20 compatible implementations during its nearly 20-year history, resulting in a $4 billion industry. However, the management of Java EE by Oracle (unintentional or not) of Java EE (unintentional or not) stalled innovations, and while other standards have developed, the Java community worldwide and CIOs at all major enterprises desired an open standard for Java within their enterprise.

In its early stages, J2EE grew somewhat quickly from J2EE 1.2 up to J2EE 1.4, as the platform needed to address the immediate requirements of the enterprise. Beginning with Java EE 5 in May 2006, the pace began to slow down as the platform began to mature, and it was 3 years and 6 months between releases. After Java EE 7, which was released on June 12...

MicroProfile value proposition

For customers who trust Enterprise Java to run their production workloads, Eclipse MicroProfile provides customers with a vendor-neutral specification for Enterprise Java microservices. Eclipse MicroProfile enables them to better fulfill the needs of the business via improved agility and scalability, faster time-to-market, higher development productivity, easier debugging and maintenance, and continuous integration and continuous deployment.

The benefits customers get by using Eclipse MicroProfile are the same benefits gained by using microservices. In general, according to Martin Fowler, a respected software developer, author, and speaker, microservices provide the following benefits (https://martinfowler.com/articles/microservice-trade-offs.html):

  • Strong module boundaries: Microservices reinforce modular structure, which is particularly important...

Summary

In this chapter, we have discussed the new trends in software development, consisting of polyglot deployments using new approaches, such as microservices, containers, mobile, and Internet-of-Things (IoT) running on-premises and in the cloud; and in hybrid or multi-cloud environments. These trends required the evolution of Enterprise Java in the microservices world, which is what MicroProfile addresses. The four forces that fuel the digital economy, namely, cloud, mobile, IoT, and open source, have contributed to the need for organizations to have multi-speed IT departments, which are necessary to maintain and evolve their existing applications as well as to take advantage of new technological trends to develop new applications that can help them to remain competitive.

Eclipse MicroProfile, a vendor-neutral specification founded by the community for the community, is one...

Key benefits

  • Create cloud-native microservices with ease using this detailed guide
  • Avoid vendor lock-in when implementing microservices using Eclipse MicroProfile
  • Discover why MicroProfile is a great specification for building microservices in multi-cloud environments

Description

Eclipse MicroProfile has gained momentum in the industry as a multi-vendor, interoperable, community-driven specification. It is a major disruptor that allows organizations with large investments in enterprise Java to move to microservices without spending a lot on retraining their workforce. This book is based on MicroProfile 2.2, however, it will guide you in running your applications in MicroProfile 3.0. You'll start by understanding why microservices are important in the digital economy and how MicroProfile addresses the need for enterprise Java microservices. You'll learn about the subprojects that make up a MicroProfile, its value proposition to organizations and developers, and its processes and governance. As you advance, the book takes you through the capabilities and code examples of MicroProfile’s subprojects - Config, Fault Tolerance, Health Check, JWT Propagation, Metrics, and OpenTracing. Finally, you’ll be guided in developing a conference application using Eclipse MicroProfile, and explore possible scenarios of what’s next in MicroProfile with Jakarta EE. By the end of this book, you'll have gained a clear understanding of Eclipse MicroProfile and its role in enterprise Java microservices.

Who is this book for?

If you’re a Java developer who wants to create enterprise microservices, this book is for you. Familiarity with Java EE and the concept of microservices will help you get the most out of this book.

What you will learn

  • Understand why microservices are important in the digital economy
  • Analyze how MicroProfile addresses the need for enterprise Java microservices
  • Test and secure your applications with Eclipse MicroProfile

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
