Amazon DynamoDB is a fully managed NoSQL database service that allows to create database tables that can store and retrieve any amount of data. It automatically manages the data traffic of tables over multiple servers and maintains performance. It also relieves the customers from the burden of operating and scaling a distributed database. Hence, hardware provisioning, setup, configuration, replication, software patching, cluster scaling, etc. is managed by Amazon.
It is common scenario when Lambda needs to write and read data from DynamoDB table, we do not need to worry about connectivity between services as traffic goes via the Internet and is allowed by default. What if our scenario is little bit more complicated our Lambda function is deployed inside VPC?
