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.

Let’s take a short trip down memory lane. Media gateways, routers, home location registers (HLRs), IP Multimedia Subsystem (IMS), and so on were components that made up legacy telecom systems. Customized hardware, operating systems, and other software were required to offer telecom services to customers. These legacy network devices were very expensive and had high operating costs. Therefore, customers ended up with high operating expenses (OPEX) and capital expenses (CAPEX). That resulted in a lock-in with long-term contracts with the telcos for support and maintenance. Another byproduct of such environments was that scalability came at a premium and self-healing capability was minimal or non-existent.

IP-based technologies gradually replaced legacy networks, to the point where even legacy services such as voice (phone) communications are now delivered over IP (VoIP). This led to the ubiquitous wireless data networks of today, of which 5G is the latest incarnation. Telcos...
