For proponents, serverless computing provides workforce solutions, efficiency, and cost savings in the enterprise. Everyone else? They may need some more convincing on the benefits of this newer technology.
If you are unsure about making an investment in serverless computing, consider the six points below.

Serverless computing 101
1. What is serverless computing?
In the most basic sense, serverless computing is a cloud computing service that simplifies code deployment by running snippets of back-end code that developers write for a single short-lived task or function. Only the precise amount of computing resources needed to complete the task get performed–no more, no less. Customers, in turn, pay a fraction of a penny each time a task or function gets deployed.
2. How “serverless” is serverless computing?
The term “serverless computing” isn’t entirely accurate. There is, in fact, an actual server, but it is run by a cloud provider instead of a person. The “serverless” part of the term refers to users no longer needing to manage the servers that run their code.

4. What are the benefits of serverless computing?
Serverless computing is inexpensive–you only pay for what you use. If no task is executed, there is no charge (the user is only billed down to the nearest 100 milliseconds.). Further, since there is no virtual infrastructure for a user to manage, serverless computing reduces operational costs and increases worker efficiency.
5. Who typically uses serverless computing?
Businesses running websites and apps with a need for back-end services or analytics.

6. What can’t serverless computing do?
Like most nascent technologies, serverless computing has limitations in regards to security, monitoring, and optimization software supporting the technology, not to mention there is the potential for latency or performance issues. Serverless computing is not suited for high-performance computing due to resource limits put in place by cloud providers. Partnering with cloud providers for serverless computing initiatives also introduces the potential for common concerns such as vendor lock-in or lack of control or responsiveness. In addition, serverless functions also remain stateless. Tasks may be re-used and re-executed, but currently, there exists no state storage.
