The solution makes it easier to configure changes into our data center, but the user interface needs to be made more user-friendly
Pros and Cons
- "The centralized configuration is its most valuable feature."
- "The only drawback that we are seeing is the user interface is still a little complex and difficult to use. It needs a more user-friendly interface."
What is our primary use case?
How has it helped my organization?
It is now easier than before we had ACI to configure any new changes into our data center.
What is most valuable?
The centralized configuration is its most valuable feature.
What needs improvement?
The only drawback that we are seeing is the user interface is still a little complex and difficult to use. It needs a more user-friendly interface. I do not use it daily. Every time that I have to go back and configure something, it is very difficult and confusing to remember how to do it and where the menu are located.

Professional Services Engineer at a tech services company with 51-200 employees
We have been able to deploy new applications more efficiently and faster
Pros and Cons
- "We can support policy based on our intent, then that gets rendered into the policy that we will be using for Fabric."
- "It is more about resolving bugs early on in the code. Otherwise, as the product gets more mature and those bugs get discovered sometimes by the customer, then Cisco will resolve them."
What is our primary use case?
We are putting ACI into replace the customer's legacy networks, so it's a migration project.
How has it helped my organization?
We have been able to deploy new applications more efficiently and faster.
What is most valuable?
We can support policy based on our intent, then that gets rendered into the policy that we will be using for Fabric.
What needs improvement?
It is more about resolving bugs early on in the code. Otherwise, as the product gets more mature and those bugs get discovered sometimes by the customer, then Cisco will resolve them.
What do I think about the stability of the solution?
It is pretty good once it is in, then up and running. The stability is fine. I haven't had many issues.
What do I think about the scalability of the solution?
The product is scalable. You can scale east-west by adding in additional leaf switches. I haven't experienced any scale issues so far, which is good.
How are customer service and technical support?
The technical support is good. We have Cisco SEs assigned to this project, and we have used them. They are pretty responsive. We have been happy with them.
Which solution did I use previously and why did I switch?
That decision would have been made by the customer internally, but they would do a LAN upgrade and an RFP. In this case, Cisco ACI came out as the winner.
How was the initial setup?
It took quite a bit of time to get the design completed in advance. However, once the core ACI Fabric was in and migrated on, the initial setup is fairly easy. It's the same with any new deployment.
What about the implementation team?
We are the supplier to the customer and the Cisco partner. We are actually doing the implementation, and the customer hired us to do it.
What was our ROI?
It saves time and resources.
Which other solutions did I evaluate?
The only real competitor to this product is VMware NSX.

It is a very stable product.
What do I think about the scalability of the solution?
I deployed it in a small environment (a lab), so I cannot comment on scalability.
Which solution did I use previously and why did I switch?
Going from legacy data center stuff to Cisco ACI, I saw the value it could offer the company that I was working with.
How was the initial setup?
The initial setup was a bit complex. ACI was just out at that time, and there wasn't support at that time. This was the first year it came out. The support and deployments in Africa weren't considerable and resources were a problem. I am from South Africa. So, it was something that we taught ourselves.
There is support for it now.
What about the implementation team?
It was implemented in-house.
What was our ROI?
We did not see ROI since this was in a lab.
What other advice do I have?
Get more support from Cisco, as far as the product's concerned. Training is a must.

Still implementing.
What do I think about the stability of the solution?
It is very stable.
How is customer service and technical support?
I would rate the technical support as a nine out of ten.
How was the initial setup?
The initial setup is complex, because we had to work with Cisco Professional Services to find the correct solution for our implementation.
What about the implementation team?
We directly used Cisco Professional Services for our implementation. They are very professional.
Which other solutions did I evaluate?
We investigated different products and found that ACI can be used with different workloads (e.g., legacy permits) or with different systems, like Microsoft Hyper-V. Cisco ACI is more flexible as a product.
What other advice do I have?
Pay attention to the implementation and interconnections between the data centers with this product.

Network Architect at Air France
It is easy to add more automation processes, as it is very scalable
Pros and Cons
- "I have found the SDN features to be the most valuable."
- "The product needs to be more visible on the Internet and have the ability to be integrated into more software developments."
What is our primary use case?
Our use case is to change our network architecture and install new free data centres for our company.
How has it helped my organization?
It has been able to transverse all the processes between two companies merging into one: Air France and KLM.
What is most valuable?
I have found the SDN features to be the most valuable.
What needs improvement?
The product needs to be more visible on the Internet and have the ability to be integrated into more software developments. For example, with Amazon, you can click and deploy SDN with firmware, but not with SDI. It needs simpler process to be deployed everywhere.

For how long have I used the solution?
One to three years.
What do I think about the stability of the solution?
It is very stable.
What do I think about the scalability of the solution?
It is really scalable. It is the most scalable product that I have tried.
We have been one year on the project and it is very scalable. We have tested it in our data centres, and it's easy to add more automation processes.
How is customer service and technical support?
I would rate the technical support as an eight out of ten, because it can be very difficult to find the right person to provide us answers. Our project needs a lot of knowledge with very complex solutions.
How was the initial setup?
It has a very complex setup, because it is a complex solution. However, we have a great level of knowledge.
What about the implementation team?
We used Cisco directly and an integrator. We had very good experiences with both of them.
Which other solutions did I evaluate?
We evaluated Cisco ACI vs VMware.
Now, I don't want to switch to another solution. I want to use this one, because it is the only solution that we tried for our use cases to unclog holes, resources, and work loads.
What other advice do I have?
It is a very good solution to improve architecture. Read the literature.
