Cisco Cloud Application Policy Infrastructure Controller Release Notes, Release 4.1(1)

If you have a private cloud, you might run part of your workload on a public cloud. However, migrating workload to the public cloud requires working with a different interface and learning different ways to set up connectivity and define security policies. Meeting these challenges can result in increased operational cost and loss of consistency.

To alleviate this issue, you can use the Cisco Cloud Application Policy Infrastructure Controller (APIC) to extend a Cisco Application Centric Infrastructure (ACI) Multi-Site fabric to Amazon Web Services (AWS) public clouds.

This document describes the features, bugs, and limitations for the Cisco Cloud APIC.

Note: Use this document with the Cisco Application Policy Infrastructure Controller Release Notes, Release 4.1(1) and Cisco ACI Multi-Site Orchestrator Release Notes, Release 2.1(1), which you can view at the following location:

For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Exists In

CSCvo06626

When a cloudExtEpg matches on a 0/0 network and has a bi-directional contract with two cloud EPGs, such as cloudEpg1 and CloudEpg2, this can result in inadvertent communication between endpoints in cloudEpg1 and cloudEpg2 without a contract between the two EPGs themselves.
