When cloud computing came into vogue, some viewed it as simply running software in someone else’s data center, or the proliferation of virtualization. But as cloud has matured, it has become clear that cloud computing, public or private, is an industry-changing paradigm shift.
In a similar way, some view serverless computing as nothing more than a meta-definition for cloud computing. But like cloud computing, serverless means so much more.
For example, Platform-as-a-Service (PaaS) offerings are often too prescriptive and confining, and Infrastructure-as-a-Service (IaaS) can be both too generic and too limiting. The true serverless movement is more abstract, promoting computing in the small (think microservices), right-sized APIs, stateless components, and reliable units of processing that are similar to transactions, yet lighter weight and less restrictive.
Whether these components run on one server or 100, on your desk, or in the cloud should be of no concern. What’s important is that serverless computing enables you to focus more closely on solving a problem without spending time building servers, installing an OS, worrying about patches and upgrades, or network, security issues, and so on.
