The main difference between Hostinger's VPS and Cloud hosting is how resources are allocated and managed. VPS (Virtual Private Server) hosting provides dedicated resources on a single physical server, giving you more control and isolation compared to shared hosting. Cloud hosting, on the other hand, uses a network of interconnected servers to provide scalable resources. This allows for greater flexibility and redundancy, as resources can be adjusted dynamically based on your website's needs. Cloud hosting is ideal for handling varying traffic levels and ensuring high availability.
