Hosting a software application on the web usually involves managing some quiet server infrastructure. Typically this suggests a virtual or physical server that must be managed, also because the OS and other web server hosting processes required for our application to run. Employing a virtual server from a cloud provider like Amazon or Microsoft does mean the elimination of the physical hardware concerns, but still requires some level of management of the OS and therefore the webserver software processes.
The software runs on a computer. once we use a cloud provider the code is running on a server. So, why is it called serverless? The service provider handles it, rather than a Developer who need not care for the server. This is often a few contract and defined communication (API) between two parties who handle separate concerns. The developer performing on the business logic can specialize in their business logic. The provider, who has got to operate serverless instances and for several reasons, can specialize in running the workloads.
Serverless Architecture is used in various industries including media, entertainment, CRM, and so on. Its architecture provides significant benefits regarding time-to-market, labor, and infrastructure cost. The developer, the person who handles the business workloads, and should not concern about the servers and other resources allocation. Serverless Architecture aisles the free path for the developers to travel with the business needs. Most of the Big-Scale companies work on Serverless architecture
The serverless movement has just begun, and we can expect the vendors of the cloud to heavily invest in enhancing the capabilities and have a set of serverless offerings. The monitoring and operational management of FaaS, DevOps teams, serverless frameworks will still mature. The agility and globalization demands, IoT proliferation, chat and voice bots, LessOps, serverless, containerization and tons more trends are at play here. All of those will speed up the serverless adoption. Many organizations are getting to migrate their production environments to serverless.
