Edge Computing Patterns for Solution Architects

By: Ashok Iyengar, Joseph Pearson

Overview of this book

Enriched with insights from a hyperscaler’s perspective, Edge Computing Patterns for Solution Architects will prepare you for seamless collaboration with communication service providers (CSPs) and device manufacturers and help you in making the pivotal choice between cloud-out and edge-in approaches. This book presents industry-specific use cases that shape tailored edge solutions, addressing non-functional requirements to unlock the potential of standard edge components. As you progress, you’ll navigate the archetypes of edge solution architecture from the basics to network edge and end-to-end configurations. You’ll also discover the weight of data and the power of automation for scale and immerse yourself in the edge mantra of low latency and high bandwidth, absorbing invaluable do's and don'ts from real-world experiences. Recommended practices, honed through practical insights, have also been added to guide you in mastering the dynamic realm of edge computing. By the end of this book, you'll have built a comprehensive understanding of edge concepts and terminology and be ready to traverse the evolving edge computing landscape.

SDN

As the term implies, software is used to provide NFs. It is done by using application programming interfaces (APIs) to communicate with network hardware and direct network traffic over a virtual overlay network. SDN aims to bring the benefits of cloud computing to network deployment and the management of networks by delivering them as code.

The devices, such as a router or switch, in a traditional network are only aware of the status of the network device next to it. SDN, on the other hand, can manage all the devices because of the centralization of network control.

Simply put, companies are using SDN because it’s a way to efficiently control network traffic and can be scaled as needed. SDN separates the control plane (that is, routing and packet forwarding functions) from the data plane (that is, underlying infrastructure). The brain of the SDN network is the centralized SDN controller, which offers a secure network since network administrators can set access...
