Implement client-side encryption to encrypt the data before it is transmitted to the S3 buckets.

Configure server-side encryption with Amazon S3 managed keys (SSE-S3) for all uploaded data.

Apply S3 bucket policies enforcing server-side encryption with AWS KMS keys (SSE-KMS) for all uploads.

Enable default encryption using AWS KMS customer-managed keys (CMK) for the S3 buckets.

Use AWS Cost Explorer to generate a monthly cost report filtered by EC2 instances. Configure Amazon Simple Email Service (Amazon SES) to send an alert when the threshold is exceeded.

Set up an AWS Budget for each account with a monthly period, scoped to EC2 costs. Configure an Amazon Simple Notification Service (Amazon SNS) topic to notify when the budget threshold is reached.

Create an AWS Lambda function that processes the AWS Cost and Usage Report data daily. Use Amazon EventBridge to trigger the Lambda function and send notifications via Amazon SNS if EC2 costs exceed the threshold.

Deploy an Amazon CloudWatch dashboard to track EC2 billing metrics and set up a CloudWatch alarm that triggers an SNS notification when the monthly spending surpasses the threshold.

Set up a daily cron job using Amazon EventBridge to trigger an AWS Lambda function that synchronizes the EC2 instances with the NAS.

Configure an Amazon EBS Multi-Attach volume for the EC2 instances to share. Write code to synchronize the volume with the NAS weekly.

Mount an Amazon EFS file system to the on-premises servers and the EC2 instances. Copy the video assets to the EFS file system and serve content from it.

Order AWS Snowball Edge Storage Optimized devices. Copy the archived footage to the devices and ship them to AWS.

Use AWS DataSync to transfer the archived footage over the VPN connection to Amazon S3.

Package the application code into a Docker container image and upload it to Amazon Elastic Container Registry (Amazon ECR).

Create an Amazon ECS task definition with AWS Fargate compatibility. Configure the task to use the ECR image. Modify the Lambda function to trigger the ECS task via the AWS SDK when new files arrive in S3.

Use AWS Step Functions to orchestrate multiple Lambda invocations in parallel. Increase the Lambda memory allocation to the maximum.

Create an Amazon ECS task definition with EC2 compatibility. Configure the task to use the ECR image. Modify the Lambda function to trigger the ECS task via the AWS SDK when new files arrive in S3.

Migrate the CSV files to Amazon FSx for Lustre and process them using an Amazon EC2 Auto Scaling group. Update the Lambda function to trigger EC2 instances.

Create a VPC endpoint for Amazon RDS and associate it with the Lambda function.

Attach the Lambda function to the VPC and configure it to use the private subnet.

Establish a VPN connection between the Lambda function's execution environment and the private subnet.

Modify the VPC route table to include a route for the Lambda function's security group.

Configure the Lambda function to use an encrypted Amazon EFS file system mounted to /tmp, using an AWS KMS key for encryption.

Assign the Lambda function an IAM role with permissions to access AWS KMS. Use KMS to generate a unique data key for each session, encrypt the data with this key before writing to /tmp.

Use a third-party encryption library within the Lambda code to generate and manage encryption keys, encrypting data before storage.

Integrate an external key management service hosted on EC2 instances to provide encryption keys for each Lambda invocation.
