IaC : Infrastructure as Code

What is IaC?

Infrastructure as Code (IaC) automates the provisioning of infrastructure, enabling your organization to develop, deploy, and scale cloud applications with greater speed, less risk, and reduced cost.

Presentation

The purpose of this demo is to demonstrate the possibilities of Infrastructure as Code (IaC) in a MultiCloud context. Then we automatically deploy an application and the associated monitoring and supervision tools, using a CICD pipeline.

Technologies

• Cloud Provider: IBM Cloud, AWS Cloud, AZURE
• Tool Chain - CICD: Git, GitLab, GitLab-CI
• IaC: HashiCorp Suite: Terraform, Consul
• Provisioning and Configuration management: Ansible
• Big Data and Monitoring: ElasticSearch, Logstash, Kibana, Filebeat, Metricbeat
• Container: Docker
• SC: AWS Route 53, DockerHub

Script

• CICD: continuous integration and continuous development with an automated GitLab pipeline (on IBM Cloud IaaS).
• IaC: Terraform + Consul (Hashicorp suite) for infrastructure deployment
• Ansible: Application deployment (wordpress and database)
• Big Data and Monitoring: We think SRE, and we will deploy an ELK chain for monitoring the application using Filebeat and Metricbeat as collector Agent
• MultiCloud: on AWS = the application, on IBM Cloud = ToolChain and on AZ or IBM Cloud = Big Data ELK
