Measuring the ROI of Serverless Computing: Is it Worth the Investment?

Introduction

Serverless computing has been gaining popularity in recent years, and for good reason. By allowing developers to build and deploy applications without worrying about the underlying infrastructure, serverless computing offers a promising solution for businesses looking to reduce costs and improve scalability. But is serverless computing worth the investment? In this article, we’ll explore the return on investment (ROI) of serverless computing and examine the key factors that contribute to its value proposition.

What is Serverless Computing?

Before we dive into the ROI of serverless computing, it’s essential to understand what it is and how it works. Serverless computing is a cloud computing model in which the cloud provider manages the infrastructure and dynamically allocates computing resources as needed. This approach eliminates the need for provisioning, patching, and scaling servers, allowing developers to focus on writing code and building applications.

With serverless computing, applications are built using functions, which are small, reusable pieces of code that can be executed independently. These functions are typically stateless, meaning they don’t store data or maintain sessions between requests. Instead, they rely on external services, such as databases and file storage, to manage data and state.

Cost Savings: The Primary Benefit of Serverless Computing

One of the most significant benefits of serverless computing is its cost savings. By eliminating the need for provisioning and maintaining servers, businesses can reduce their capital expenditures (CapEx) and operating expenses (OpEx). According to a study by Gartner, serverless computing can reduce infrastructure costs by up to 80% compared to traditional cloud computing models.

Another study by 451 Research found that 62% of businesses that have adopted serverless computing cite cost savings as the primary benefit. This is because serverless computing only charges for the compute time used, rather than a fixed rate for server usage. This pay-as-you-go pricing model can lead to significant cost savings, especially for applications with variable or unpredictable workloads.

Subsection: Case Study - Amazon Web Services (AWS) Lambda

A great example of the cost savings of serverless computing is Amazon Web Services (AWS) Lambda. Lambda is a serverless computing platform that allows developers to run code without provisioning or managing servers. According to AWS, Lambda can reduce costs by up to 95% compared to running servers on Amazon Elastic Compute Cloud (EC2).

For instance, if an application is handling 100,000 requests per day, with an average duration of 100 milliseconds, the cost of running on EC2 would be approximately $150 per month. In contrast, the cost of running on Lambda would be approximately $7.50 per month, a reduction of 95%.

Scalability and Flexibility: Key Drivers of ROI

In addition to cost savings, serverless computing offers scalability and flexibility, which are key drivers of ROI. With serverless computing, applications can automatically scale to meet changing workloads, without the need for manual intervention. This ensures that applications are always available and responsive, even during peak usage periods.

According to a study by Forrester, 77% of businesses that have adopted serverless computing cite scalability as a primary benefit. This is because serverless computing allows businesses to quickly respond to changing market conditions and customer needs, without being constrained by infrastructure limitations.

Subsection: Case Study - The New York Times

A great example of the scalability of serverless computing is The New York Times. The newspaper’s developers built a serverless application using AWS Lambda to handle its online commenting system. The application processes tens of thousands of comments per hour, with a peak load of over 100,000 comments per hour during major news events.

Thanks to serverless computing, The New York Times was able to handle this large and variable workload without experiencing any performance issues. The application’s scalability and reliability ensured that readers could engage with articles and share their opinions without interruption.

Increased Productivity: A Hidden Benefit of Serverless Computing

Another often-overlooked benefit of serverless computing is increased productivity. By eliminating the need for infrastructure management, developers can focus on writing code and building applications, rather than worrying about servers and scalability.

According to a study by Redmonk, 70% of developers say that serverless computing has improved their productivity, allowing them to build applications faster and with fewer resources. This increased productivity can lead to faster time-to-market, improved innovation, and greater competitiveness.

Subsection: Case Study - Netflix

A great example of the increased productivity of serverless computing is Netflix. The streaming service’s developers built a serverless application using AWS Lambda to handle its video transcoding workflow. The application processes thousands of hours of video content per day, using a complex workflow that involves multiple functions and services.

Thanks to serverless computing, Netflix’s developers were able to build and deploy the application quickly and efficiently, without worrying about infrastructure constraints. The application’s scalability and reliability ensured that Netflix’s customers could enjoy high-quality video content without interruption.

Conclusion

In conclusion, serverless computing offers a compelling ROI for businesses looking to reduce costs, improve scalability, and increase productivity. By eliminating the need for infrastructure management, serverless computing allows developers to focus on writing code and building applications, rather than worrying about servers and scalability.

As we’ve seen in this article, the cost savings of serverless computing can be significant, with businesses reducing their infrastructure costs by up to 80%. Additionally, serverless computing offers scalability and flexibility, allowing applications to automatically scale to meet changing workloads, without the need for manual intervention.
