The Definitive Guide to Modernizing Applications on Google Cloud

By: Steve (Satish) Sangapu, Dheeraj Panyam, Jason Marston

Overview of this book

Legacy applications, which comprise 75–80% of all enterprise applications, often end up being stuck in data centers. Modernizing these applications to make them cloud-native enables them to scale in a cloud environment without taking months or years to start seeing the benefits. This book will help software developers and solutions architects to modernize their applications on Google Cloud and transform them into cloud-native applications. This book helps you to build on your existing knowledge of enterprise application development and takes you on a journey through the six Rs: rehosting, replatforming, rearchitecting, repurchasing, retiring, and retaining. You'll learn how to modernize a legacy enterprise application on Google Cloud and build on existing assets and skills effectively. Taking an iterative and incremental approach to modernization, the book introduces the main services in Google Cloud in an easy-to-understand way that can be applied immediately to an application. By the end of this Google Cloud book, you'll have learned how to modernize a legacy enterprise application by exploring various interim architectures and tooling to develop a cloud-native microservices-based application.

BeyondCorp (a new approach to enterprise security)

BeyondCorp can be thought of as a new approach to enterprise security. Despite being a relatively new standard in the world of the security domain, BeyondCorp has become very popular and widely adopted. It is based on the Zero Trust model and aims to remove the need for a VPN by securing the individual users themselves, allowing users to access resources from anywhere in the world securely.

BeyondCorp takes a different and very interesting approach to security. Where traditional security platforms try to keep everyone out of the business assets by creating a plethora of firewalls and defenses and only giving access to those who have been authenticated, BeyondCorp removes the need of having an inside and an outside (with a firewall in-between). Instead, it sees every request (for access), regardless of it was made by a member or not, and grants access based on several contextual factors and conditions. This Zero Trust model means...
