The web's new architecture, Modular, has fundamentally shifted the relationship between business and technology, requiring a new model of thinking that dictates who'll win and why. The concept of headless CMS emerged as a solution to traditional Content Management Systems' limitations, with companies like Impossible Foods adopting modular architectures to support growth and customer needs. The COVID pandemic accelerated this shift, making composable content and modular architecture essential for digital success. As the ecosystem around Modular continues to evolve, understanding its principles is crucial for anyone involved in content or customer experience.
