Serverless Computing: Advantages and Drawbacks

The tech-driven world has offered many beneficial innovations for developers and users. Serverless computing is one such mechanism that has streamlined the activities of developers, limiting the traditional infrastructure constraints.

Serverless infrastructure is a cloud computing framework that enables users and developers to execute codes in a better environment. The mechanism has experienced significant progression lately in terms of implementation. Sources state that the serverless architecture crossed the market valuation of $11.38 billion in 2023 and will possibly reach beyond $106.12 billion by 2033.

Let us dive deeper into serverless computing to explore its workings, along with its advantages and disadvantages.

What is Serverless Computing?

Serverless computing denotes a cloud model that allows developers to write codes and develop applications without managing primary infrastructure. Here, third-party service providers allocate, manage, and scale necessary infrastructure. In short, developers can freely run codes and develop software while utilizing serverless computing without thinking much about the servers.

The pioneering days of serverless cloud models can be traced back to 2008, with the launch of Google App Engine (GAE). Google launched the GAE platform to support web application development and hosting with the integration of Google data centers.

Nevertheless, the terminology ‘serverless’ received prominence not before 2012. Gradually, tech giants, such as Amazon and Microsoft, introduced their serverless functions which ultimately contributed to its remarkable growth.

How Does Serverless Computing Work?

The operating process of serverless architecture is complex yet understandable. Developers require servers to run codes while building applications. Running codes include resource allocation for computing and storage, patching or update implementation, load management, and others. These activities often lead to latencies, operation failure, etcetera. For which the development process often stops.

Under such circumstances, third-party service providers come onto the scene. These parties enable an invisible server for the developers on which the latter can conveniently execute codes without getting bothered about the server restrictions. The service providers take care of the loads, patches and other elements. Developers process their codes on the serverless software or infrastructure that the service providers manage and align the required functions with API interfaces.

The serverless model is available in various forms, such as software as a service (SaaS), infrastructure as a service (IaaS), function as a service (FaaS), and platform as a service (PaaS). The best part about integrating serverless architecture is the charges which are flexible, on-demand, and follow pay-as-you-go structure.

Advantages of Serverless Computing:

Cost-effectiveness: Serverless architecture is cost effective as most of the functions are on-demand and usage-based. Therefore, users only have to pay for the functions they utilize.

Flexibility: While executing complex codes and programming languages on serverless infrastructures, developers can operate flexibly without encountering any server-related difficulties.

Reduced Latency: Third-party service providers of serverless computing look after the functions, loads, patches, and everything during code execution. Hence, users can run codes and develop applications quickly without significant latencies.

High scalability: Serverless architecture provides easy methods of scalability, as all the functions are available on demand. Thus, the functions scale back automatically after a complete code execution.

Drawbacks of Serverless Systems:

Less control: When using a serverless framework, users give all the management and execution control to third-party service providers. Therefore, the former often lack activity control.

Security: Third-party server usage triggers remarkable security risks. Such models handle several users at a time, which means many developers run code together on a single server. Any network weaknesses or vulnerabilities in the servers can cause security breaches.

Vendor lock-in: Different serverless vendors provide diverse functionalities that users often intend to explore for performance enhancement. However, it is nearly impossible due to vendor lock-in, which means switching from one provider to another is difficult due to compatibility issues.

Wrapping Up!

Cloud computing is an ever-evolving technology that has allowed individuals and organizations to flexibly operate with complicated tasks. Serverless computing is a cloud framework that enables developers and companies to operate in a more agile environment. The mechanism eliminates traditional server obstructions like latency. Alongside that, scalability is simplified in serverless architecture. All these factors contribute to its constant progression. Explore more technologies and innovations with our blogs.
