Efficient, Cost-Cutting Serverless Technology
Cloud computing mechanism is highly useful in significantly altering the outlook towards business and its development. The past few years have witnessed an exemplary evolution in the use of cloud computing. With innovative technologies, cloud computing too has evolved and has been fragmented from on-premise cloud to virtual machines, from containers to becoming serverless.
Serverless computing has not only provided business agility and cost-effectiveness but has also brought about a profound change in the pricing model of the services. Traditionally, cloud computing demanded a constant amount to be paid for the virtual machines used to run websites, irrespective of whether the cloud servers were used or not. But serverless computing has provided for payment only about the service usage and the time taken for its execution. With serverless computing, the communication and transfer of data about the services are carried out through APIs. APIs help serverless applications to retrieve data and utilize them following the business logic. Most APIs also come with various payloads, data formats, and query string structures. Serverless computing has transformed cloud computing from infrastructure as a service (IaaS), to platform as a service (PaaS), to function as a service (FaaS). It works in a more granular way, unlike the traditional computing methods. It provides fragmented code blocks, which when organized sequentially, works as a single unit. It also facilitates the configuration of the memory size as per the requirement of the code block.
Authentication is another vital facet that needs attention to ensure application security and data accessibility only by authorized users. The use of a NoSQL database helps to eradicate the use of DBAs and facilitates easy integration of the entire system in use. Serverless computing system provides a fully regulated service by the cloud service providers, making the work process more efficient and quick. The functions carried out with the help of serverless computing are triggered by the events and thus prevents any unnecessary usage of the services. With the use of serverless computing, cloud service providers are made accountable for the entire underlying infrastructure management, leaving the more complex functions to be handled manually. According to the studies carried out by RightScale 2018 State of the Cloud, there has been a 75 percent growth rate in the use of serverless computing, making it the leading computing system in use. Cloud Foundry 2018 reported that 46 percent of the surveyed companies use serverless computing.
Serverless computing thus comes across as a turning point in the field of technology, that enables the adoption of new and innovative ideas, and incorporate them effectively into the current solutions of the already existing cloud infrastructure, to produce the most favorable results.
