AWS Lambda is revolutionizing the cloud. Developers are creating interesting use cases day-by-day with the Lambda. In our use case, we are using Lambda as the Web backend. Lambdas and APIGateway together form a scalable, highly available and cost-efficient backend for your web application. When we use Lambda as our backend, we need our Lambda to talk to the databases. Usually databases reside inside an VPC, so that they are secured and not exposed to public world. Initially, if you want your Lambda to talk to an RDS(Relational Database Service), then you need to expose the RDS with the publicIP which helps Lambda to perform CRUD operations with the database. This exposing of database to the internet will be vulnerable. So, the obvious solution will be adding the Lambda inside an VPC. Lets see how we can add the Lambda within the VPC.
