Summary

Market Overview:

The global serverless architecture market size reached US$ 10.8 Billion in 2022. Looking forward, IMARC Group expects the market to reach US$ 30.2 Billion by 2028, exhibiting a growth rate (CAGR) of 17.8% during 2023-2028.

Serverless architecture is a software design technique allowing developers to create and execute services without managing the underlying infrastructure. It also assists in writing and deploying codes, while a cloud provider provisions servers to execute the applications, databases, and storage systems. It reduces the cost of DevOps and enables developers to design and enhance their apps without being limited by server capacity. As a result, it finds extensive applications in the information and technology (IT), telecom, healthcare, manufacturing, media and entertainment, retail, and e-commerce industries.

Serverless Architecture Market Trends:
Presently, there is a rise in the utilization of cloud-based applications for accessing, storing, and retrieving files from a web-enabled interface. This, along with the growing demand for serverless architecture to eliminate the management of the server, represents one of the key factors driving the market. Moreover, the increasing awareness about the benefits of streamlining operations, such as increased cost efficiency, improved productivity and communication, better time management, and reduced risk, is propelling the growth of the market. In addition, there is a rise in app development as it allows users to have easy and functional access to information, products, services, and processes in real-time. This, coupled with the increasing digital-centric business models across the globe, is offering lucrative growth opportunities to industry investors. Besides this, the growing employment of the internet of things (IoT) to optimize manufacturing operations, track assets with increasing accuracy, target existing consumer services, and create entirely new services and business models is positively influencing the market. Apart from this, the escalating demand for serverless architecture by various organizations to eliminate expensive traditional and time-consuming approaches, such as purchasing new hardware components, installing, configuring, and troubleshooting, is bolstering the growth of the market.
