A web application is basically reliant on the communication between the client and server. The user device has to install the client and send requests to the server to receive the corresponding resource or service. Web application development has seen a long journey from hardware servers to cloud hosting and serverless architectures.

What is Serverless Architecture?

By reading the term, you might get the impression of no servers. Instead, it means that the applications’ parts are distributed among multiple servers without creating or managing the infrastructure for it. The computing service provider has the responsibility of organising and maintaining the server infrastructure. A java certification training can help you learn serverless application development.

What are the Advantages of Implementing Serverless Architecture?

• Reduced cost is the first immediate benefit of using a serverless architecture. Using hardware servers is always an expensive affair since you have to purchase your own equipment and organise its proper maintenance. Cloud computing gives you the chance to lease your desired computing capacity from a service provider. The infrastructure cost could be drastically reduced with the implementation of serverless architecture. There are no charges for idle time. Thus, you only will pay for your usage.
• Using a serverless architecture gives the developer the possibility of using third-party services in the development. You can use a server-side language with third-party services. These types of approaches can decrease the effort in development for creating mobile application back-end architecture.
• The implementation of Function-as-a-Service gives you a proper computing platform to deploy code as event-driven functions. We can say that serverless architecture is like a form of microservice architecture. However, they are not the same thing. 
• Serverless architectures make it perfectly possible to achieve scalability. Traditional hardware servers might not be able to provide this level of scalability and often require redundant computing power. With a serverless architecture like AWS Lambda, you can quickly scale horizontally as much as you like and distribute the computing resources according to you. You can pursue a Java certification course for better understanding. 
• In a Serverless Architecture, applications are deployed as separate functions. This naturally increases the overall resiliency; each function gets executed independently. A single failure won’t be affecting the entire application performance.   
• Implementing a Serverless Architecture keeps you away from the headache of service availability. The service provider has to take the entire responsibility of its service availability. 
• Latency could be a big setback to the performance of an application. This problem could be major if the distance to the data centre is greater. However, this problem is negligible in a Serverless Architecture. The majority of the server service providers ensure global coverage and presence to minimise latency and improve response time. A java certification training can help you start with serverless application development. 
• Using a Serverless Architecture requires no administration because there are no physical or virtual services. Thus, we can reduce all the administration related costs and failures. 
• Using Serverless Architectures can reduce the overall time-to-market. This is actually the ultimate benefit resulting from the above-mentioned benefits. You don’t have to spend time on gathering resources, hiring administration, receiving the best simpler code, ready-to-use third-party services, and more. Serverless architecture can provide you with a considerable competitive advantage.

The Improvement in Productivity and Flexibility

Using a serverless app makes it simpler to implement in a web app and mobile app development than the traditional way. When you have FaaS, you no longer need to worry about multi-threading or to handle HTTP requests on your own. This simplification gives you the scope of faster and more innovation. This innovation helps to boost the morale of the developers and improve their productivity. Serverless computing has virtually no limitations since the developers could make any additions and restructure the app whenever required.

Improved Customer Satisfaction

The main aim of business software is to improve audience engagement and satisfaction. When you implement a serverless architecture, you are able to capture more users in a short period of time. Developers are able to create a unique brand experience and improve customer loyalty. Apps developed with a Serverless Architecture can instantly launch new features to fulfil the requirements of their customers. Developers can quickly fix any minor bugs or shortcomings faster without actually hindering the infrastructure. This constant flow of improvement in mobile or web app development can ensure full customer satisfaction.

Environmental Impact on Hosting and Computing

The advent of global warming has made conservation of the environment really important. When a company hosts their own data centres, they have to run their servers all the time with the help of huge physical resources and energy. This could create a huge environmental impact and increase the carbon footprint of the company. In comparison, serverless architecture lets you purchase servers on demand. It could reduce the resources required to keep your development going.

Major Examples of Serverless Applications Development

Developers can develop different types of applications with the help of a serverless environment. However, here are some of the most prominent examples of serverless applications:

Web Applications Development

There’s no need to maintain and organise a dedicated server for your web apps and websites. The vendor could provide you with proper cloud services to build your own API and run the code. A Java certification course can help you develop effective web applications.

Back-End for IoT

An IoT network is connected to hundreds of applications and generates tons of data for the application server. Serverless architecture can eliminate any downtime, provide registration logic, database capabilities, activation code, etc.

SaaS Integration

Developing a SaaS application includes the ability to handle fluctuating loads. This is a big challenge with the traditional architectures as they have to cope up with ever-changing demands. A Serverless Architecture can automatically scale according to the continuously changing needs of SaaS applications.

Back-End for Mobile Applications

Serverless Architectures are very capable of providing different types of environments in a matter of keystrokes. You can develop mobile applications with serverless architecture that reacts and performs like native applications. The serverless functions can easily perform multiple tasks with the help of the cloud vendor.
