Cloud computing is often perceived as costly, but is it really? In this talk, we’ll explore the financial and operational implications of migrating a legacy Ruby on Rails (RoR) application from a traditional VPS (Virtual Private Server) setup to Microsoft Azure. We’ll break down the cost considerations, including compute, storage, and scalability, and compare them to the maintenance overhead of a VPS. You’ll learn how Azure services like Azure Linux VM, Azure Database for MySQL, and Azure BlobStorage can optimize performance and reduce long-term costs. By the end of this session, you’ll have a clear understanding of whether cloud computing is a cost-effective solution for your (legacy) applications.
