Going Serverless on AWS

What is the hype with serverless architecture? And why are most businesses moving towards outsourcing their computing needs?


Long gone are the days where physical hardware was the sole that ran the server, which was indeed a lengthy and expensive affair. AWS is one such vendor, which provides backend services to users. They need not worry about the underlying infrastructure and just focus on writing and deploying code.
In its essence, the software is written as a collection of functions, however, with serverless architecture, the application can be operated at any scale, which can perform distinct tasks. This is where AWS steps-in, it can run the parallel ‘containers’ that can be monitored and scaled separately. The term ‘serverless’ however, is misleading because there are servers that are being used. As a matter of fact, developers do not have to be concerned with server space and infrastructure and focus on their coding.


Below are some of the reasons why the shift to serverless is inevitable.


Quick Turnaround Time:

Switching to serverless means that developers can create apps in a matter of days, as it is not required to upload code to the servers or do any backend configurations to release a working version of an application. Developers are graced with the option of either uploading the code at one shot or one function at a time since the vendor has given the application as a collection of functions. In the same vein, developers can easily update the application one function at a time, again saving time.



Applications that run on serverless infrastructure are able to seamlessly scale-up when the demand arises. Depending on the requirement at a given point, the serverless application will automatically scale up or down. For instance, as the user base grows and usage increases, the serverless infrastructure tends to scale-up to account for the increased usage.


Cost Efficient:

With serverless, there is no need for servers to be constantly running. Therefore, businesses save in operational costs because of the lowered expenses for both computing and manpower. Moreover, serverless offers its users a pay-as-you-go scheme, unlike traditional servers. In the past, developers would have to predict how much server space would be required. They would have to pay for it regardless if they used it or not.


Best User Experience:

The end goal of any product or service is to make sure that the users have the best possible experience. Serverless infrastructure enables teams to focus all their efforts to make sure the users have the best features available to them, leading to a seamless experience.


Going serverless with AWS gives you an array of options that you can focus on to innovate new ways of innovation with increased flexibility. Moreover, developers do not have to stress about managing and operating servers, and instead can spend their time creating applications that are scalable and reliable. If you haven’t already switched over to serverless, what are you waiting for?
