Cisco ACI Pros

We are doing automation from ACI and we have integration with Azure. With the Azure stack integration we can have total automation. We can configure the EPGs from there, and we can configure load balancing functionalities from there as well. The most useful feature is that you don't need to configure anything on ACI itself. You can configure on Azure and it will provision your application.

The best part of ACI is that it can integrate with a lot of virtual environments like VMware, Hyper-V, and KVM.

In a very general way, the ease of access, ease of use, and ease of connecting the system is a valuable feature in itself. The solution doesn't really increase detection rates as that is not what it was created for. Threat prevention comes in from other devices that might be connected into the Cisco ACI that monitors external traffic. It maintains what end-of-life products would be doing and offers other opportunities to unify solutions.

One area where it has an advantage... is that you're able to reuse a specific integration. If you add another server, you can use a specific integration and assign it to another port.

Once we have it running, it should be easier for us to program our IT rather than going case-by-case, by switches and different elements, or program it by hand.

It is a complete re-write of everything that you've ever thought of from a networking standpoint.

It's improved the static configuration of our data center switching environment. But it's added some challenges to our ability to operationalize it and make it easier for people to manage.

With ACI, if you need more capacity you can just buy more and plug them in without needing to do anything else. All of the sudden that infrastructure is there for me to use, configure, and add stuff to.

Cisco ACI Cons

Where there is room for improvement from ACI is for Layer 2 and Layer 7 packages. Normally, when you're updating your ACI fabric or you're introducing new Layer 4 to Layer 7 devices, there are some constraints, there are some limitations... When you are doing device packages you will not have the functionality of ASM. It's like WAF, web application firewalls. So you need to configure it manually.

Better troubleshooting features would be helpful. In ACI, it can be a big mess, a real headache to troubleshoot a single issue... The troubleshooting part, and the information that ACI gives you, sometimes don't give you a proper, inside picture of what's going on within the fabric.

Figuring out how to implement the product for clients is the area we struggle with the most every day. Perhaps an enhancement would be artificially intelligent solutions, but that would be further down the road.

One of the things that makes it a lot more complicated is the way contracts are handled in ACI. Contracts are like their own access lists. They can improve the setting up of contracts between devices a lot. It can be simplified.

Biannually, there is a new design delivered by Cisco. Thus, you are always running behind the new design, and it never stops. With Cisco ACI, this has been a nightmare.

It would be nice if I could specify network-centric in my design, and the system would organize and set itself up in that way.

So far we've had very few issues, a couple of routing things that were glitches within ACI.

In terms of improvement, I would like to see some sort of way to baseline the system in a network-centric fashion.

They should improve the GUI, make it simpler. They also need to improve its integration with other automation tools.

For Multipod we need Layer 3 devices that support multicast. Customers ask: "Why can't ACI do that? Why do we need a dedicated Layer 3 device for this?" If they go for Multi-Site there is no need for that, ACI can do it. So Cisco needs to increase the Multipod features in ACI.
