This article will by no means be a complete review of the security in Cisco’s Application Centric Infrastructure solution. What I’ll be concentrating on in this blog is the built in security you get with ACI as well as the security you’ll get in your virtual environment when you use ACI along with Application Virtual…
Last month I wrote about creating layer 2 outside access in Cisco ACI. Perhaps even more necessary is creating layer 3 outside access or even doing both layer 2 and layer 3. It’s likely you’re going to need to connect your ACI fabric to your current network just to get traffic between the two environments.…
Most likely when you start moving to an ACI fabric you’re not going to forklift your entire network and put in a new one. That’s just not realistic. More likely you will start migrating lines of business or certain applications to ACI, but these applications will need to be able to communicate with end point…
Part of the beauty of Cisco Application Centric Infrastructure is the idea of contracts. In ACI we talk a lot about the idea of the policy driven network. Those policies are what we call contracts. Contracts aren’t totally unlike ACLs, but there are some big differences. First, ACLs usually go between IP addresses or subnets,…
This article describes how we connect physical, or bare metal, servers to the ACI Fabric. A while ago I wrote an article about adding VMware integration to your ACI fabric. This is of course a very important step, as about 70% of people’s workloads are virtual. However, that number has been pretty static over the…
I thought I’d take a break from the series of writing how to setup Cisco ACI and talk a little bit about the programmability features available within ACI. Any of the other articles I’ve written where I’ve shown how to set things up using the GUI, you can also do by using REST API calls…
