For the last few years, serverless app development has been on the rise and seems not to stop soon. With more investments and innovations in technology by cloud vendors, serverless architecture has very big potential. Earlier before the serverless architecture, business and developers were required to purchase hardware servers to host the applications, then came the cloud hosting and now here we are.
But why is the serverless app development technology so promising and being considered the future of the apps by many?
In this article, we will explore the meaning of serverless architecture, the benefits of SAD, and what to expect from this innovation.
What is a Serverless Architecture?
Despite the name, the word serverless doesn’t mean there are no servers.
In simple terms, serverless architecture means the application developer does not need to purchase servers to run their back-end coding.
In serverless architecture, the developer doesn’t need to create or maintain infrastructure since it is the work of serverless cloud vendors but only write and deploy their application coding.
What’s the secret behind Serverless App Development technology?
The server-side applications from the developer are split into small executable functions. Then the serverless cloud servers system run the functions continuously, which can easily be monitored and scaled.
Serverless architecture has two models:
Back-End as a Service
The software developer only writes and maintain frontend web or mobile application since the backend is developed and managed by the third party. The third-party vendors provide cloud-hosted services such as database management and hosting.
Function as a Service
In this model, developers can write and update small programs that can be executed in response to an event. These functions are then executed independently.
What’s are the benefits of Serverless App Development?
Now that we understand what Serverless app development is and the secret behind it is, let us look at some of the benefits:
Serverless architecture is very cost-effective, as the user only pays for computing power that the applications have used, unlike cloud computing where users pay fixed fees ending up paying for unused CPU.
In serverless architecture, there is no need for business to buy servers or commit capital for maintenance.
This is one of the app development solutions that many organization have been looking for, improve the application functionalities without worrying about whether the server can handle.
The serverless architecture providers handle all the application scaling by distributing computing resources on demand.
This is a huge benefit for the business as it can now concentrate on improving and growing its application.
The time of application response is affected by the user’s geolocations, a number of users making the request and the network latency.
With serverless architecture, the problem of latency is greatly improved since the providers have access points on a global scale.
By use of serverless architecture, the application response time is reduced and therefore improving application performance.
Improved Scope of UX Design
The first impression is very important to customers using your application.
Customers just want to see applications that are user-friendly and don’t care about the coding part.
By using serverless architecture, the software developer will have more time on designing the application since most of the tasks are done by the serverless app development solutions providers.
Reduced Delivery Time
Software developers can develop applications faster using third party services such as application program interface (APIs) and extensions.
By use of serverless app development approach, one can develop an app faster with little effort as there is no need to worry about the server infrastructure.
In a world that is very competitive, the business should look for effective ways to deliver their apps products in the market using the best technologies. Serverless architecture is one of these technologies that will enable the business to save costs when developing apps. By using serverless applications, developers can build modern applications faster and spending more time on innovative apps. Perhaps, this is the biggest technology in the future of apps development.
FAQs About Serverless Application
Q. What is Serverless Application Development (SAD)?
A. Serverless Application Development refers to building and running applications without the need for managing underlying infrastructure. It allows developers to focus on code, while the cloud provider manages the execution environment.
Q. How does Serverless Architecture work?
A. Serverless architecture involves splitting server-side applications into smaller, executable functions. These functions are executed and scaled automatically by the cloud server system, in response to specific events.
Q. What are the models of Serverless Architecture?
A. The two primary models are Back-End as a Service (BaaS), where backend services are hosted by a third party, and Function as a Service (FaaS), where developers write small, independent functions executed in response to events.
Q. What are the benefits of Serverless App Development?
A. Benefits include reduced operational costs, enhanced scalability, improved latency, more focus on user experience design, and faster delivery time for applications.
Q. How does Serverless Architecture reduce costs?
A. In serverless architecture, costs are based on actual computing power used by the application, rather than a fixed fee, leading to savings on unused CPU resources.
Q. Why is Serverless Architecture good for scalability?
A. It allows automatic distribution of computing resources on demand, enabling businesses to scale their applications without worrying about server capacity.
Q. How does Serverless Architecture improve latency?
A. Serverless providers have global access points, which reduce the response time of applications, enhancing performance irrespective of the user’s geolocation.
Q. Can Serverless App Development improve UX Design?
A. Yes, it allows developers to devote more time to designing user-friendly interfaces, as the burden of backend management is handled by the serverless architecture.
Q. What is the impact of Serverless Architecture on delivery time?
A. Serverless Architecture enables faster development and deployment of applications by utilizing third-party APIs and services, thus reducing the overall time to market.
Q. Is Serverless Application Development the future of app development?
A. Many experts believe serverless is the future due to its cost-effectiveness, efficiency, and ability to allow developers to focus on innovative and user-centric applications.
