A big reason is the proliferation of micro-services based applications in highly redundant and highly available cloud infrastructures. Add to that a desire for most enterprises to integrate cloud based workloads with legacy on-premises applications, and we have complex hybrid cloud deployments to deal with as the result.

I think this three-part series on new network models for cloud computing ( part 1 , part 2 , and part 3 ), while almost a year old, is quite good. Erik Smith, notably known for his outstanding posts on storage and FCoE, takes a stab at describing some of the differences between SDN and network virtualization in this post.

Having segmentation between infrastructure providing data processing and data storage is an example of a broad IT security architectural pattern. As the technology portfolio changes, especially with the rapid adoption of the cloud, the architectural patterns included in the CCA have to be reevaluated periodically.

OS X provides an SSH agent by default, but on Linux systems you will probably have to manually run an SSH agent and add the appropriate SSH key: eval `ssh-agent -s` ssh-add ~/.ssh/keyfile.pem. Metadata can be assigned either via cloud-config parameters passed when the instance is spawned, or via modifications to the fleet config files.
