Serverless Stack for Mobile Application Development

There is a famous saying that technological advancement in the past 20 years has eclipsed the changes happening in the entire history of Mankind. The current digital gadgets which we use, such as wearable watches, Tablets, Smartphones, were not even thinkable a few decades back — the same goes with Softwares. The Technology world has evolved at an astonishing pace in the last 20 years.

Serverless Stack for Mobile Application Development

With the advent of Cloud computing, this usual pattern was changed; it offers flexibility to take server space and other computing capabilities on rent. Cloud vendors offer a pay-per-usage model, which was extremely beneficial for Application developers and owners. Cloud computing now has users pay only for those resources, which are in use — they don’t have to think about the maintenance and other aspects.

What is Serverless?

We believe the term ‘Serverless’ does not mean there is no involvement of Servers. However, these Services and Infrastructure resources are provided by a specific 3rd Party vendors as a backend service.

The developers can purchase these backend services on a pay-per-usage basis. Most of the cloud Vendors provide database storage services as Function-as-a-Service platforms. These platforms help developers to execute codes on the edge without storing any data.

What are the advantages of serverless computing?

Lower costs and “Pay as you Use.”

Compute resource cost is one of the biggest concerns for any organization, as it occupies most of the budgetary allocations.

Seamless Scalability — Everyone wants their mobile application to be used by millions of users, but the biggest hurdle is if we can scale the application in a similar proportion of our increasing user base. This question haunts the developers and Application owners, as they are not sure of the extent of the scalability of their application.

Here comes Serverless architecture for our rescue; it allows unlimited scaling, without worrying about the provisioning of Servers.

Simplified backend code

It offers Function-as-a-Service, which is a big boon for the developers. They can create and execute simple functions that can perform their intended purpose, like making Application programming interface calls and several other system functions.

Quicker turnaround and less time to Market — The application market is witnessing a cut-throat competition; If your competitor gets it first, then you will lose it. In this case, Serverless architecture offers the capability to add new functions and features in a few hours, instead of weeks or months.

It enables developers to cut down the time to market and deploy and release the updates so quickly. Developers get an option to add and modify the code in a piecemeal fashion.

Lower Latency for end-users — However, as code can run closer to the end-user and can run virtually from anywhere, it reduces the latency issues up to a great extent.

What is Serverless Stack?

The first thing to remember, if we talk in general terms — a Stack is a collection of Operating Systems, tools, languages, databases, scripting language, web servers, frameworks, and APIs, etc. All of these pieces of the “Stack Collection” come together to develop an entire software solution.

Nowadays, every mobile application has some common traits like scalability, security, and maintainability. A serverless stack enables developers to build the right product, which can specially fulfill these additional requirements.
