We decided to use AWS Lambda for several serverless tasks such as

• Managing AWS backups
• Processing emails received on @{Amazon SES}|tool:17| and stored to @{Amazon S3}|tool:25| and notified via @{Amazon SNS}|tool:396|, so as to push a message on our @{Redis}|tool:1031| so our @{Sidekiq}|tool:1078| @{Rails}|tool:990| workers can process inbound emails
• Pushing some relevant @{Amazon CloudWatch}|tool:401| metrics and alarms to @{Slack}|tool:675|
