Market Overview

The global function-as-a-service market size was valued at USD 3.25 billion in 2022. It is estimated to reach USD 34.94 billion by 2031, growing at a CAGR of 30.2% during the forecast period (2023–2031). An increasing number of businesses and developers who work for them are adopting serverless computing, which is a major factor in expanding the function-as-a-service industry.

Function as a Service, or FaaS, is a type of cloud computing that eliminates the need for managing application infrastructure, enabling software developers to operate their enterprises more successfully. A platform that offers infrastructure as a service (FaaS) to application developers constructs, manages, and runs application packages on the developers' behalf. Several causes fuel the industry's growth, including the growing tendency away from development operations (DevOps) and toward serverless computing, agility, scalability, and the maturing of hosted services. The tendency among enterprises toward the optimization of microservices and the administration of various platforms is another factor that is projected to support the market's expansion.

Since the introduction of FaaS, the programmable cloud's capacity to host application installations has grown rapidly. According to Oracle, the amount of sensitive data shared on the cloud will increase 600 times over the next few years. Many cloud service providers, such as AWS Lambda, Azure Functions, and many others, offer FaaS. From the designers' standpoint, these models' purpose is to offer benefits, including simple installations, reduced operational efforts, and pay-as-you-go pricing.

Market Dynamics

Global function-as-a-service market drivers

Increase in the app development market

The rise in consumer interest in practical applications designed for various operating systems, including Android and iOS, has presented app developers with new commercial options. In addition, a major boost in demand for app development technologies has been brought about by a rise in the number of smartphones, an increase in the adoption of BYOD policies, and a surge in the number of applications. It is expected that one of the best ways to make build, test, and release cycles intrinsically agile is to use function-as-a-service, which boosts the productivity of software developers.

In addition, developers can construct massively scalable and event-driven apps by using the serverless approach. This is possible because the serverless approach eliminates the need for them to manage underlying infrastructure issues such as servers, storage systems, networking, and others. Due to the advantages discussed above, an increasing number of businesses and developers who work for them are adopting serverless computing, which is a major factor in expanding the function-as-a-service industry.

Rise in need to eliminate server management challenges

IT managers and administrators must deal with ongoing management responsibilities because of the ongoing expansion of the data landscape and the growing need for additional servers. Even if they use a variety of technologies, such as Microsoft System Center Configuration Manager, it cannot meet all of the requirements. They are faced with various issues concerning server management, including server deployment, changes to system configuration, management of Windows patches, application packaging, change testing, application deployment, and change administration, amongst others. As the vendor manages the servers, this technology helps developers tackle problems linked to servers and their management. This reduces the amount of money invested in DevOps, which in turn results in cost savings.

Issues associated with third-party apis

Several issues, such as vendor control, vendor lock-in, multitenancy problems, and security and compliance concerns, are associated with serverless computing due to third-party APIs and hampers the function-as-a-service market. The absence of system control during the implementation of APIs has several consequences, such as system downtime, loss of functionality, forced API upgrades, unexpected limits, and cost changes.

In addition, multitenancy problems have been found in several cloud computing frameworks, as function-as-a-service can have problems with security, robustness, and performance. Moreover, the dependency of developers on vendors for debugging and monitoring tools is considered a pitfall with serverless computing, as debugging distributed systems is difficult and requires significant access to several relevant metrics to identify the root problem.
