With the advent of microservices, Kubernetes, public cloud, and hybrid computing, SREs and system engineers are facing more complexity than ever before. To tackle this problem, you need a unified control plane to manage the networking among your applications running on these distinct platforms. This definitive guide shows you how to automate networking for simple and secure application delivery with Consul.

Author Luke Kysow, Consul engineer at HashiCorp, demonstrates how this service mesh solution provides a software-driven approach to security, observability, and traffic management. Once you learn how to implement zero-trust networking by deploying Consul on multiple platforms, you'll be able to take control of application traffic, prevent outages, view metrics, integrate with legacy systems, and more.

Dive into the characteristics of service meshes, zero-trust networking, and traffic-shaping patterns
Deploy Consul on multiple platforms, including Kubernetes and virtual machines
Learn how to secure, monitor, and manage your application traffic with Consul
Use this guide to deploy and operate applications as a system administrator, DevOps engineer, or developer
