Ansible for DevOps

Ansible

Descripción

As data centers grew, and hosted applications became more complex, administrators realized they couldn’t scale their manual systems management as fast as the applications they were enabling. That’s why server provisioning and configuration management tools came to flourish. Server virtualization brought large-scale infrastructure management to the fore, and the number of servers managed by one admin (or by a small team of admins), has grown by an order of magnitude. Instead of deploying, patching, and destroying every server by hand, admins now are expected to bring up new servers, either automatically or with minimal intervention. Large-scale IT deployments now may involve hundreds or thousands of servers; in many of the largest environments, server provisioning, configuration, and decommissioning are fully automated.
