Serverless web applications: What you need to know before building one

Serverless web applications, initially popularized by AWS Lambda in 2014, have gained widespread adoption due to their benefits in agility, scalability, and efficiency for customer-facing applications and critical workloads. In serverless architecture, while the cloud provider manages the underlying servers, developers can focus on writing application code, resulting in cost-efficiency, automatic scalability, faster development, flexibility, and high availability. Despite these advantages, developers face challenges such as the need for thorough observability planning, time-consuming configuration of functions, sparse documentation, and the complexity of determining application structure. To address these issues, developers should ensure readiness for serverless, utilize observability tools like New Relic, plan sufficient configuration time, and create an efficient development workflow. The blog emphasizes the importance of having the right knowledge and tools to achieve serverless success, highlighting New Relic's AWS Lambda monitoring solution for enhanced visibility and insight into serverless applications.
