In the previous chapter, we looked at modern design and development principles that are essential to quality and maintainable code and stable yet flexible application design. Learning is through some of the most used design patterns and their implementation using the .NET Core code. Distributed computing is an art of computing to interact with a collection of independent systems in the field of computer science. In this chapter, you will get an opportunity to understand the fundamentals of this computing and application in the enterprise world. It starts with the definition, followed by its core characteristics, such as concurrency, scalability, transparency, security, and so on. In the modern world, distributed computing has a vital role to play.

This chapter will cover the following topics:

• What are Distributed applications?
• Multithreaded programming
• Concurrency versus parallelism
• Design challenges to build the distribution
• Scalability
• Security
