Multi-Cloud Infrastructure as Code
-
2 mins
For any enterprise, willing to address multi-cloud infrastructure, the following questions might pop up
- How do Technology Partners(Independent Software Vendors) or Developers do CI/CD in a Hybrid-Cloud environment?
- How to share APIs with Partners or Developers to build next-generation intrinsic security infrastructures?
- How to integrate Public Cloud (AWS, Azure, GCP) to work in a true Multi-Cloud environment?
- How to provide a “Try for Free” experience before engaging the new Partner or Developers into the ecosystem.
New Portfolio Demands
Some of the new requirements include:
- Continuous Joint Development, Setup dedicated pipelines for Strategic Partners.
- Dynamic Provision Multi-Cloud Infrastructures
- Custom and Open blueprints. Partners or Developers should be able to Maintain & Manage the state of blueprints
Public Cloud - AWS as an Example
AWS Two-tier Application
In this image, I show an example of a two-tier application. Just to provision this app on AWS, we need to create many resources in AWS. Some of the resources are listed here.
- Resources
- VPC
- Security Groups
- Subnets
- Internet gateway
- EC2 Instance
- Elastic Load Balancer
- IAM key-pair
- AMI
- Web server binaries.
Infrastructure as Code (IaC)
HashiCorp Terraform provides the foundation for cloud and on-premises infrastructure automation using infrastructure as code for provisioning and compliance in the cloud operating model.
AWS Two-tier Application -IaC example
- Terraform It is a declarative programming tool. “declarative” is a style of programming where the program describes the desired results without explicitly listing commands or steps to perform. It uses HCL syntax. It is like a human-readable declarative configuration format. One can use this tool for any kind of infrastructure (PaaS, SaaS, IaaS). It is a plugin-based architecture where every provider has a plugin. E.g. AWS plugin, GCP plugin, or VMW plugin. And the best part is it is all open source
AWS Two-tier Application -IaC example:
```
File: main.tf
provider "aws" {
region = "${var.aws_region}"
version = "~> 2.33"
}
resource "aws_vpc" "default" {
cidr_block = "10.0.0.0/16"
}
resource "aws_internet_gateway" "default" {
vpc_id = "${aws_vpc.default.id}"
}
resource "aws_route" "internet_access" {
route_table_id = "${aws_vpc.default.main_route_table_id}"
destination_cidr_block = "0.0.0.0/0"
gateway_id = "${aws_internet_gateway.default.id}"
}
…etc…
```
AWS Serverless Apps
- Resources
- AWS Kubernetes Service
- AWS Cloud Container Registry
- AWS Lambda – Serverless Function
- AWS IAM Authenticator
Conclusion
- Build Hybrid-Cloud Environment Labs with a click-of-button from Blueprints.
- Deliver Complex Test Lab Environments On-Demand for new Partners and Developers in mins.
- Increase efficiency by reducing developer manual resources required to deploy & test hybrid environments. Invest in automation.
