Evolution from Traditional Computing to Cloud Native

The journey from traditional to Cloud Native computing is like upgrading from a bicycle to a sleek, high-speed electric scooter. Traditionally, applications were built to run on specific servers or machines. It was like having a giant, dedicated kitchen in your house to cook for yourself.

Imagine having access to a global network of kitchens, each specializing in different cuisines. You don't need to build your own kitchen; you just use the ones you need, when you need them. That's the essence of the shift.

In the traditional model, everything was local. You had to plan for the maximum load your kitchen could handle, even if most of the time, you were only making a sandwich. With Cloud Native, you can dynamically adjust your resources. It's like having a magical kitchen that automatically expands when you're preparing a feast and shrinks back when you're just making tea.

This evolution isn't just about where your applications run; it's about how they're built. Traditional applications were like large, monolithic structures - all the functions bundled together. Cloud Native applications, on the other hand, are like well-organized cities, with different services communicating seamlessly.
