Pulumi: The Modern Approach to Infrastructure as Code

As organizations strive to modernize their infrastructure, Pulumi has emerged as a compelling alternative to traditional Infrastructure as Code (IaC) tools. Pulumi bridges the gap between infrastructure and application development, offering developers the ability to define and manage infrastructure using general-purpose programming languages. But what makes Pulumi unique, and how does it compare to other IaC tools? Let’s explore!
