What issues are you experiencing with Sidekiq?   ? What does your infrastructure look like? I actually cheated a bit with my instance and actually run Sidekiq on the web servers. It's not best practices, but it works. If you were to separate out the sidekiq from the web servers, you'd create a separate application within your environment.
