ACI at its core is a ReST API platform to manage a large scale data center fabric. Moving away from human CLI constructs, ACI uses objects that provide structured data interaction tools that make it easier for programing languages to automate tasks. In this lab session, you will learn to build a small web based application that will implement tasks in a real ACI fabric. We will show the student how to use programing tools and libraries such that you understand the fundamentals and graduate from Perl/Expect scripts into web based applications that could be front ends to the future of how you interact with your datacenter network.
