Business Benefits of Serverless Computing

Serverless computing today has emerged as a revolutionary approach to building and deploying applications. Imagine developing and deploying apps without spending time managing servers. It allows developers to do this because the architecture required to scale and run the apps is handled for them.

With this blog, I will delve into the numerous business benefits of serverless computing and how it can transform how companies operate in the digital age.

What Is Referred To As Serverless Computing?

Serverless Computing is a cloud-based model that allows developers to write and deploy code to containers that cloud service providers manage. It is more than just running code or containers; it is an entire stack of services that respond to events or requests and scale dynamically per requirements. AWS Lambda, Microsoft Azure Functions, Google Cloud Functions and IBM Cloud Code Engine are some examples of serverless computing platforms. These platforms allow developers to run code or containers responding to specific events or requests, such as HTTP requests, database triggers, or message queries. Developers can use various programming languages, frameworks, and tools to build serverless applications and integrate them with other cloud services, such as databases, storage, analytics, messaging, and security.

Benefits Of Using Serverless Computing

• Easy to deploy: Serverless technology is easy to deploy, allowing developers to focus on writing code rather than managing servers or infrastructure. It provides a runtime environment for code execution, which a cloud service provider collects. The cloud provider takes care of everything else, such as allocating machine resources, scaling the application, and billing users only for resources used. Serverless technology supports continuous integration and delivery (CI/CD) pipelines, which can automate the testing and deployment of code. To deploy a serverless application, the developer only needs to package and give the updated code to the cloud service provider. The cloud service provider makes this updated code available for new requests or events. The update does not affect any code during execution, as each function is isolated in its environment.
• Low-cost solution: It allows running code without managing or paying for servers or infrastructure. It uses a cloud service provider to handle the execution, scaling and billing of the code. Organizations only pay for the resources they use without worrying about servers' provisioning, maintenance, or security. It also reduces the computing power and human resources needed to build and deploy applications. Serverless technology also helps save time, money and effort, enabling businesses to focus on business logic and user experience.
• Auto-Scaling and Load Balancing: Serverless systems automatically adjust resources based on demand, eliminating the need for manual scaling and load-balancing configurations. This reduces the risk of resource shortages during traffic spikes and keeps costs in check during quiet periods.
• Highly scalable: Enables applications to adjust to the demand automatically without requiring manual intervention or configuration. It relies on a cloud service provider to allocate machine resources, such as servers, databases, or networks. The cloud service provider can dynamically scale the infrastructure based on workload, such as number, events, or requests. This allows applications to handle fluctuating or unpredictable workloads like seasonal spikes or sudden surges. Serverless computing can also help applications scale effectively and efficiently without requiring developers to worry about the underlying infrastructure. It can reduce the cost and complexity of scaling applications, as organizations only pay for resources they use and do not have to provision, maintain, or secure servers.
• Improved latency: Helps improve latency by running code closer to the end-users. Latency is the time it takes for a request and a response to travel between the user and the server. The longer the distance, the higher the latency. Serverless computing can reduce the discount by using a cloud service provider with a global network of data centers, which can execute code in the user's nearest location. This also helps improve the performance and user experience of applications. A few examples of serverless computing platforms that can run coe at the edge, the closest point to the user, is AWS Lambda@Edge and Cloudflare Workers. By running code at the edge, these platforms can reduce latency compared to servlet platforms that run code in a single region, such as AWS Lambda.
• Enhanced flexibility: Serverless computing allows developers to use different programming languages, frameworks, and tools to build applications. It also enables developers to integrate their applications with other cloud services, such as storage, databases, analytics, messaging and security. Serverless computing can also support a microservices architecture, which can break down applications into smaller and independent functions that can be updated and deployed independently.
• Easier Integration: Serverless platforms support integration with various other cloud services, making it easier to connect your application to databases, storage, AI, and machine learning services, enhancing the functionality and capabilities of your application.

Final Words

Serverless computing is a promising technology that can transform how applications are built and run in the cloud. It offers many benefits for businesses, such as reduced operation costs, increased scalability, faster deployment, improved latency, increased flexibility and more innovations. It helps businesses save time, money and effort, allowing them to focus on their core products and user experience. While it has its challenges and limitations, such as cold starts, vendor lock-in, debugging difficulties, security risks and statelessness, businesses should carefully evaluate their needs and requirements before adopting serverless computing for their applications.
