Serverless computing is a modern infrastructure model that provides backend services as required. Serverless computing has numerous advantages for developers such as flexibility, scalability, and cost reduction. Developers don’t have to worry about managing backend servers as these are handled by the vendor, and only pay for the server space they use, making it a more cost-effective option. Serverless architecture is scalable and will automatically adjust as the user base or usage increases. It enables quick deployments, updates, and reduces latency by running code closer to the end-user.
However, there are also some disadvantages to serverless computing. Testing and debugging become more challenging, and serverless computing introduces new security concerns, especially for applications that handle personal or sensitive data. Serverless architectures are not built for long-running processes, which limits the applications that can be cost-effectively run using this model. Performance may also be affected as serverless code may need to ‘boot up’ when it is used, causing delays.
Serverless computing offers a more cost-effective and simple option for certain kinds of situations, while being an impractical solution for others. Developers needing to decrease their go-to-market time and construct lightweight, flexible applications that can be expanded or updated quickly may find serverless computing very advantageous, as it would reduce costs for applications that see inconsistent usage. However, those who are running large applications with a fairly constant, predictable workload may benefit from a more traditional setup, which would be less expensive on the whole.
