These days users expect the best online experience while browsing. To meet customer requirements, businesses should build web applications that are reliable, adaptable, and fast. However, it is not easy to achieve all of this cost-effectively. But No worries! Serverless Architecture is a cost-effective, reliable, and efficient approach. It is an innovative solution that is used to build and manage web applications. By 2025, its market value will increase by up to $22.3 billion.

We are going to emphasise the basic concepts of the serverless computing model, its benefits, how you can integrate this technology into your web applications, and much more. Continue reading for details.

First, let’s understand this approach and its important characteristics. 

What is Serverless Architecture? 

Serverless architecture is a cloud computing execution model where cloud service providers manage the infrastructure and run the application instead of having developers do this.

The term serverless used in this context suggests servers are absent from the system while, in reality, they remain part of the computing infrastructure. The technical term "serverless" pertains to the reality that developers don't have to manage servers. 

They only write and deploy code, and the cloud providers automatically run applications. In this way, developers can focus on building and improvising applications without worrying about dealing with infrastructure. 

Now you understand what serverless architecture is. Let’s now discuss the main characteristics of this server-free architecture in detail. 

Main Characteristics of Cloud-Native Framework

Here, we have listed some main characteristics of this advanced technology.

1. Event-Driven

Serverless applications run in response to specific events. For example, a function might be triggered when someone uploads a file, submits a form, or visits a website. This makes serverless apps highly flexible and responsive to user actions.

1. Auto-Scaling

Serverless platforms automatically adjust resources based on demand. If a website suddenly gets a surge in visitors, the system instantly improves to handle the traffic. Even when traffic decreases, it ensures optimal performance without manual effort.

1. Pay-as-You-Go

You only have to pay for the actual execution time of your functions. This makes it a cost-effective choice for businesses.

1. No Server Management

Developers don’t need to set up, maintain, or update servers. Cloud providers manage everything. These include security updates, software patches, and hardware management. It allows developers to focus on building applications.

1. Stateless Functions

Each serverless function runs independently and doesn’t remember past executions. If your application needs to store data, it must use an external database or storage service. This keeps serverless applications lightweight and efficient.

Once you understand what this approach is and its main characteristics, let’s discuss how it can be beneficial for businesses.

How a Server-Free Approach Enhances Agile Web Applications

There are various benefits to using this technology. A few of them are mentioned here.

• Adaptability: Cloud-based infrastructure can automatically handle sudden traffic increases. If many users visit a website at once, the system quickly adapts to meet the demand. When traffic slows down, it goes down and ensures smooth performance without any manual adjustments.
• Cost-Efficiency: You don't have to pay for the resources you don't use while using serverless computing. However, traditional servers charge a fixed amount for infrastructure whether you use it or not. A survey report suggests that more than 70% of AWS customers and 60% of Google Cloud customers use server-free solutions for affordable rates. Serverless eliminates these excess charges by adjusting resources based on demand.
• Faster Development: As developers don’t have to manage servers, they can spend most of their time writing and launching their codes. It automatically speeds up the development process. Hence, businesses can bring new features and products to market faster.
• Less Maintenance Work: Serverless platforms take care of infrastructure tasks. For example, server management, security updates, and system monitoring. Serverless platforms provide relief to developers who no longer need to manage servers while giving them additional time to enhance application quality instead of fulfilling administrative duties.
• Better Reliability: Serverless systems are designed to keep applications running smoothly, even if something goes wrong. If one part of the system fails, traffic is automatically redirected to a working instance. These platforms also include strong security measures to protect applications from cyber threats.

After reading about the benefits, you must think of its use cases. Here you can see the most common applications of this technique. 

Where a Server-Free Approach Works Best

Server-free technology is a great option for applications that need to improve automatically based on user demand. The following list demonstrates typical serverless deployment scenarios

1. API Backends: The platform simplifies the development of APIs that receive requests from web and mobile interfaces. These APIs improvise automatically to ensure smooth performance even during high traffic. Developers do not need to maintain servers that make the process more efficient.
2. Microservices: Serverless is ideal for implementing microservices such as small, independent units of functionality that work together. Each function runs separately. It makes the system more flexible, agile, and easier to manage. This allows developers to update or expand specific parts of an application without affecting the whole system.
3. Real-Time Data Processing: Many applications require processing large amounts of data instantly. Serverless is a great fit for IoT systems, social media analytics, and financial transactions. It can quickly handle data from multiple sources. Plus, it ensures fast and accurate processing without the need for constant infrastructure management.

4. Mobile App Backends: Mobile applications need strong and scalable backends to handle user requests, store data, and send notifications. The cloud-native framework helps by managing these processes efficiently, automatically adjusting to traffic levels. This allows developers to focus on building features rather than maintaining servers.

By using the serverless computing architecture, applications can improve effortlessly, reduce operational complexity, and improve performance without requiring constant server management.

Limitations of a Server-Free Approach

Although server-free technology has many benefits, it also comes with a few downsides. Here are some main issues to consider:

• Delay in Response: When a function runs for the first time or after being idle, it takes a moment to start. This delay, known as a "cold start," can slow down response times. It’s a concern for applications that need instant performance.
•  Limited Control: Cloud providers manage the infrastructure, which may affect developers over hardware and run time settings. This can be a drawback for apps that need precise performance tuning or resource management.
• Vendor lock-in: Different cloud providers have their serverless platforms and APIs. It is hard and expensive to move from one cloud to another as it requires many changes to the application.
• Debugging and Monitoring: Troubleshooting serverless applications is harder than traditional ones. Since functions are stateless and short-lived, special tools and techniques are required to track issues and monitor performance.

Despite these challenges, serverless remains a powerful choice for many applications. Understanding these limitations helps teams make informed decisions. However, it is not easy to accomplish these tasks by themselves. For this, they can approach a renowned mobile app development company to help them achieve their goals.
