Abstract
The timeline given in the first chapter embodies the perspective of humans using and benefiting from services. In this chapter, we now dive under the hood of this development and take a look at the service software implementations with a special focus on basic principles of complex distributed services which fulfil the requirements for modern cloud and fog applications. Over the last two decades, we have been able to observe significant architectural changes in distributed systems and networking applications which will be reflected in the text. There are also mostly orthogonal shifts towards higher reliability, efficiency, scalability and information security, as well as other beneficial non-functional characteristics. The chapter covers general software and system architectures, discusses cluster and cloud systems as well as peer-to-peer topologies, along with concrete system examples, and highlights the topics of performance optimisation and transactions as well as distributed databases.
