Multicloud Architecture Migration and Security

Book description

If you’re considering a multicloud approach to host applications, you’re in good company. According to a recent survey, 42% of the world’s organizations have adopted this strategy. But there are significant challenges and complexities to overcome. This practical report walks you through the pros and cons of migrating to these environments, particularly for securing your applications.

Cybersecurity experts Laurent Gil and Allan Liska show you how to orchestrate and manage multicloud environments, including edge technologies designed to secure and protect your environment. Managers and leaders will learn methods for distributing workloads across cloud providers as well as ways to avoid potential pitfalls when pursuing this strategy.

  • Understand the benefits of adopting a multicloud architecture—along with the trade-offs and short-term costs
  • Learn how orchestration lets you manage dozens of applications across thousands of containers in a multicloud environment
  • Explore ways to apply a consistent security policy across all cloud platforms
  • Implement layered security that includes vulnerability scanning, API gateway deployment, and web application firewalls
  • Delve into specific use cases for delivering web application security across all cloud providers
