Serverless was once seen as the future, offering easy scalability and no server management.However, the limitations of serverless for full product development are becoming apparent.Real-world applications require state, database access, and more, making serverless less suitable.Deno's decision to scale back its serverless offering signals a shift towards a full app hosting platform.Cloudflare, Vercel, and Deno are adding features that mimic traditional server capabilities.Vendor lock-in and the push for global distribution are concerns with serverless platforms.For most applications, staying within a single region is sufficient, avoiding unnecessary complexity.Serverless has limitations like execution time, memory, concurrency issues, and cold starts that impact performance.The recommendation is to use serverless for certain tasks and traditional infrastructure for full product development.Understanding the role of serverless as a specialized tool is essential for effective application development.For the core of a product, relying on servers and containers is more reliable and less complex than trying to fit everything into a serverless model.
