🌐 Introduction to Infrastructure as Code (aka IaC)
I am a Cloud Engineer who works at Tata Consultancy Services.
The key idea behind infrastructure as code is to manage the infrastructure through code.
There are various IaC tools such as Terraform,Ansible, Pulumi,AWS Cloud formation,Azure Resource Template which mainly helps in creating and managing dynamic infrastructure as per the requirement.
Three core practices for implementing IaC
👉 Define everything as code.
✏️ Reusability
✏️ Consistency
✏️ Transparency
👉 Continuously test and deliver everything as you work.
✏️ The idea is to build quality in rather than trying to test quality in.
👉Build your system from small,lossely coupled pieces.
✏️ Teams struggle when their systems are large and coupled.The larger a system is ,the harder it is to change , and the easier it is to break.
Infrastructure as Code is a Cloud age approach to managing system that embraces Continuous change for high reliability and quality.
Benfits of infrastructure as Code
👉 Using rapid infrastructure as an enabler for rapid delivery of value.
👉 Reducing the effort and risk of making changes to infrastructure.
👉 Enabling users of infrastructure to get the resources they need ,when they need it.
👉 Providing common tooling across development, operations and other stakeholders.
👉 Creating systems that are reliable,secure and cost-effective.
👉 Make governance,security and compliance controls visible.
👉 Improving the speed to troubleshoot and resolve failures.
Conclusion
To get the value of cloud and infrastructure automation, you need a Cloud Age mindset. This means exploiting speed to improve quality,and building quality in to gain speed. Automating your infrastructure takes work, especially when you're learning how to do it. But doing it helps to make changes, including building the system in the first place.
