Their solution was a full-scale migration to the cloud. Within months, their applications were modernized, their systems became more resilient, and their ability to serve customers improved dramatically. This transformation wasn’t just about adopting new technology—it was about leveraging the best cloud platform to future-proof their business.

Stories like this are becoming increasingly common as businesses across industries recognize the need to modernize their applications. Gartner predicts that by 2028, more than 50% of enterprises will utilize industry-specific cloud platforms to accelerate their business initiatives. However, with numerous cloud platforms available, selecting the right one can be overwhelming. Each provider offers unique advantages, making it crucial for businesses to align their cloud strategy with their long-term goals.

Here’s a comprehensive look at the best cloud platforms for application modernization, each offering a different blend of scalability, security, and performance.

Top Cloud Platforms for App Modernization

Best Cloud Platforms for Modernization

1. AWS – The Cloud Powerhouse Driving Global Innovation
