Having absolutely no doubt, you might be quite mindful of Amazon Web services, Microsoft Azure, and Google Cloud, and with that people hooking around these services with the term serverless computing. Every corner down there is rambling around SERVERLESS! SERVERLESS! SERVERLESS! True, isn’t it.
So, let’s first take a crisp jump on the handle, “Serverless Computing”. Well, by definition that is contributed by AWS, “A serverless architecture is a way to construct, assemble and run applications and services without having to be in charge of the infrastructure.” In simple terms, your application/product is still being deployed on servers, but all the server management kinds of stuff are done by the contributor of your serverless computing. You no longer have to allocate, cater and maintain services to run your application, software package, plug-in, databases, storage systems, and much more. Huh! That sounds like a perfectly feasible solution for all those energy and exhausting working hours you’re contributing towards deployment. Right?
Why Serverless Computing?
On the grounds of this, way back when AWS or Google cloud services were not in the frame, many challenges were obstructing a smooth sweep and maintenance of an application. Lack of resilience, insufficient data security, less alliance, and the worst scenario can be not gaining admittance into data distantly. However, with the introduction of serverless services, these challenges have been conquered terrifically. Now there is no longer a need for server space, no experts required for hardware and software sustenance, better data security, but not least at all, that is the tragic rejuvenation. And how not to mention the ease of deployment. Isn’t it? But wait! Before diving straight into evaluating, you shall have a look into the architecture and services that are proffered by serverless computing.
Two broad domains of Serverless Computing
The cloud computing service providers known to be vendors provide services to manage applications through a widespread planetary network. Focussing on the serverless infrastructure, there are mainly two aspects of it by which you can have an excellent understanding of this whole architecture thing. One is the front end and the other side is the back end.
The Front-End Solutions
The front end translates the infrastructure which is network-facing. So, it is quite the reverse. The back end is where the application, services, and devices are, like say storage devices, accompanied by the security and maintenance portals. Promptly, the front-end services impart applications and their correlative interfaces that are integral for the cloud-based service. So, anything laminating the internet can be web browsers such as google chrome, internet explorer. Primarily, the websites that you deploy falls into the front end, as they are accessible to the public/clients through the web browsers. Moving further into the front-end infrastructure, there are hardware and software components like virtualization software and many more. Besides that, it feeds a graphical user interface (GUI) to the end-users to carry on their distinguished exercises on serverless computing.
The Back-End Utilities
While setting foot over the back-end services manipulates all the programs that run applications on the front end. Fundamentally, the back-end architecture holds its base on three pillars. These are the application domain, services it proffers, and its storage. Supporting a larger number of data storage systems and servers, it provides everything requisite for front-end web applications. The few other services of the back-end comprise storage application development environments and web services among the end-users. Concerning storage, it maintains and administers any amount of data flowing all over the internet. And speaking about the popular examples of storage services, we have Amazon S3, Microsoft Azure Storage, and Oracle Cloud Storage.
As of now, the back-end is the stamina of a serverless computing system, its business is to provide productivity in the architecture and to negotiate the functions of a serverless computing environment. Also, the back-end is the most critical component in cloud architecture.

The Security Countenance
Granting the fact that the security aspect falls under the back-end architecture, it’s required to be understood independently. Well, considering storing data in vast databases, security is a consequential Section of the serverless infrastructure. It protects the cloud resources, files, systems, and infrastructure. Whats’s even better? It takes care of security to the overall cloud server. That too via virtual firewalls which not only proffer the ultimate shielding but also help in defending against any data loss.
