A solutions architect is designing a VPC with public and private subnets. The VPC and subnets use IPv4 CIDR blocks. There is one public subnet and one private subnet in each of three Availability Zones (AZs) for high availability. An internet gateway is used to provide internet access for the public subnets. The private subnets require access to the internet to allow Amazon EC2 instances to download software updates.What should the solutions architect do to enable internet access for the private subnets?

A company is designing an application where users upload small files into Amazon S3.After a user uploads a file, the file requires one-time simple processing to transform the data and save the data in JSON format for later analysis.
