Build your next cloud-based PaaS in under an hour

The charter of Open Innovation Labs is to help our customers accelerate application development and realize the latest advancements in software delivery, by providing skills, mentoring, and tools. Some of the challenges I frequently hear from customers are those around Platform as a Service (PaaS) environment provisioning and configuration.

Before you get yourself into a situation where your company is paying your favorite coffee shop’s franchise fee in cloud services and is getting the functionality of a french press, let’s think this through. There are a few things you need to consider. Are you creating EC2 instances manually? What is your staging environment like? Do you have one? Where should it live? Let’s take a few moments and discover the steps we need to take using the flowchart in Figure 1.

Figure 1: HA Cloud build out demands the use of an IAC tool set.

Note: The toolset we chose is Hashicorp Terraform [] as our Infrastructure as Code (IAC) tool, and puppet community [] for configuration management. If you choose a different set of tools, the principles in this series will still apply.
