Book Description

For companies that deliver services and gather data at the edge of their networks, an infrastructure resilience strategy is essential. IT departments within many medium to large enterprises today rely on third-party cloud or data center providers to help manage traffic and workloads across multicloud environments, content delivery networks (CDNs), and data centers. But those providers are also already busy managing internet issues for thousands of customers.

In this practical ebook, Gary Sloper of Oracle Dyn and Mark Wilkins of Global Knowledge explain proactive steps you can take to ensure resiliency against unplanned events at the network edge. IT directors and managers will learn how to balance workloads and optimize performance to counter volatility sources, such as internet threats, equipment failure, network congestion, and weather-related outages. The ebook also examines ways to steer traffic more efficiently and strengthen your security posture within a hybrid or multicloud environment.

This ebook will help you:

  • Recognize the uncontrollable and unpredictable factors that contribute to internet volatility
  • Understand the characteristics of a resilient infrastructure built to withstand volatility threats
  • Learn how managed DNS infrastructure can strengthen edge resiliency performance, availability, and security
  • Examine intelligent DNS-based edge services such as active failover, federated traffic steering, load balancing, and path optimization
