Get Started with Infrastructure as Code with this Free O’Reilly Ebook Application development has undergone drastic changes in the past few years, driven by the demand for ever-increasing performance, scale, and resiliency. Single-server and multi-server deployment models that require manual configuration and endless hours of routine drudgery are frowned upon. Today, applications are increasingly deployed on clusters of dozens, hundreds, and even thousands of containers and virtual machines. This shift requires enormous cooperation between development, operations, and traditional IT management teams. This new cooperative approach to infrastructure management led to the creation of “Infrastructure as Code” – an approach where servers, networks, firewalls, and services are abstracted to software and data. Infrastructure-as-code methodology utilizes software development best practices, such as version control systems and automated testing libraries, to build simple, easy, and repeatable, human-readable infrastructure configurations. Thanks to these tools, [ more… ]

Deploying NGINX Plus for High Availability with Chef In a previous blog post, we went over how to deploy NGINX Plus using Chef. In this blog post we will build on the Chef configs from the last blog post and use Chef to deploy a highly available (HA) NGINX Plus active/passive cluster. This post assumes that you have already run through the previous post and have a working Chef installation. If not, please review at least the first two sections in the previous post, Preparing Your Chef Environment and Downloading and Configuring the NGINX Cookbook. To set up the HA active/passive cluster, we’re using the HA solution provided by NGINX, Inc., which is based on keepalived and the Virtual Router Redundancy Protocol (VRRP). The solution comes with an interactive script for creating the keepalived configuration file, but here we’re using [ more… ]
