Distributed Computing in Java 9

Overview of this book

Distributed computing is the concept with which a bigger computation process is accomplished by splitting it into multiple smaller logical activities and performed by diverse systems, resulting in maximized performance in lower infrastructure investment. This book will teach you how to improve the performance of traditional applications through the usage of parallelism and optimized resource utilization in Java 9. After a brief introduction to the fundamentals of distributed and parallel computing, the book moves on to explain different ways of communicating with remote systems/objects in a distributed architecture. You will learn about asynchronous messaging with enterprise integration and related patterns, and how to handle large amount of data using HPC and implement distributed computing for databases. Moving on, it explains how to deploy distributed applications on different cloud platforms and self-contained application development. You will also learn about big data technologies and understand how they contribute to distributed computing. The book concludes with the detailed coverage of testing, debugging, troubleshooting, and security aspects of distributed applications so the programs you build are robust, efficient, and secure.

Chapter 10. Security

As global organizations have started to depend more on the market-leading open systems and cloud environments to increase their reach to the market and improve their business, more online transactions are going on the Internet. As more business transactions are taking place in open networks, it is equally open to the threats from the outside world. While organizations make the most of the marketing information available to the business, they are equally worried about the privacy of the information. Having business-critical applications distributed across, the communication between the clients and applications needs to be established in a more secure way.

In this chapter, we will cover the following:

  • Security issues and concerns
  • Two-way Secure Sockets Layer (SSL) implementation
  • Cloud computing security
  • Security as a service (SECaaS)
  • Security enhancements in Java 9

Let's start by reviewing security issues and concerns for distributed applications.
