Stable, scalable, and easy to manage
Pros and Cons
  • "The most important aspect of Cisco ACI in my opinion is the ease of management. Other solutions, like traditional solutions and pricier solutions—or even fabric and PAT—you have to do many configurations on a box-to-box basis, With Cisco ACI, you go on the AP and do some "next, next finish" installer."
  • "Before version 5, you could manage your firewall or load balancer from the AP. It was very basic and now they removed the whole features in the new version, so you cannot manage your load balance or firewall from your AP on L2, L4, and L7 services."

What is our primary use case?

In the last nine months, I have done two projects with Cisco ACI. Both of them were banking systems. I'm capable of selling, installing, and deploying Cisco ACI, so I know all the licenses and prices as well as how to compare the prices and establish a pre-sales team and also doing the deployment and supporting the ACA solutions. 

What is most valuable?

The most important aspect of Cisco ACI in my opinion is the ease of management. Other solutions, like traditional solutions and pricier solutions—or even fabric and PAT—you have to do many configurations on a box-to-box basis, With Cisco ACI, you go on the AP and do some "next, next finish" installer. Everything is done without having to know about the VXLAN, AVPN, MP-BGP, or ISI. In previous solutions, you had to know all these things and deploy all of them yourself, so you needed a deep knowledge of VRF and all the other BGP things. You would have to remember everything about the detail configuration, but now we just do some clicks and everything is there.

The other benefit to me is the white-listing solution that the ACI can handle. It's important to have a good knowledge of IPS and DDoS things. I always prefer to stop traffic mid-way instead of putting everything on the firewall and blocking it on the firewall. In my opinion, a firewall has very limited resources and it is possible to run out of resources easily with a simple attack, like HPing. But when you do white-listing, you just greenlight your needed traffic, not all the traffic. So this is a very big difference. And also of course, nowadays everyone is talking about the ACR tool Heat that allows customized configuration to style. These are the major things and some other things like very low latency and few hops. 

What needs improvement?

Before version 5, you could manage your firewall or load balancer from the AP. It was very basic and now they removed the whole features in the new version, so you cannot manage your load balance or firewall from your AP on L2, L4, and L7 services. They can improve this because it's a little bit hard to send traffic with PBR or EPB to the box. They're returning back. That's one area where they could improve.

For how long have I used the solution?

I've mostly worked with Cisco solutions in the last 15 or 17 years. I do everything from deploying enterprise solutions and developing data centers to building cloud applications with Cisco ACI or data solutions at the center, like MPP, GPU, AVPN, and VXLANs. Security-wise, I started with ASA and IPS then upgraded to Five Power and Snort. I also have a lot of experience with Ice and Identity solutions as well as ESA and WSA.

Cisco ACI

Learn what your peers think about Cisco ACI. Get advice and tips from experienced pros sharing their opinions. Updated: June 2025.
857,028 professionals have used our research since 2012.

What do I think about the scalability of the solution?

I believe that Cisco ACI is highly scalable. Anytime that you want to add bandwidth, you just need to add a spine and anytime you need more ports, you just need to add that. And the very cool feature is the different typology that ACI can support now. Before that, it was a stretch, especially the typology. Nowadays, everyone is talking about the IPN and the multi-part.

For bigger operations with different data centers in different locations, you can deploy multi-site and it also offers some support remotely. I've never deployed it, but you can use a virtual peak that gives this and also enables a multi-tier. That's also very helpful with customers that don't want to spend a lot of money for the cable or transceivers. And the hardware is massive. I really love the hardware. The MTBF is huge. Everything is stable.

How are customer service and support?

I was also in Malaysia for many years as a CTO at a company before COVID and was a Cisco partner. So I know how to create tickets. I've experienced how they respond and escalate tickets. I was the business owner and promised stability and availability to my customers. I asked and they opened a ticket for me, and I'd give it to my friend. I only needed to interact with Cisco techs very few times. But for licensing things and hosting, I use support all the time.

How was the initial setup?

In most cases, you just plug in the cables and it even has the cable cave, a guard system, attached spine to spine. In my opinion, the initial part that involves creating the overlay is very easy compared to an MP-BGP or VPN solution. So in that case, it definitely takes hours, especially if the site that you are working with ACI is multi-tenant. If it's multi-tenant and you are not using ACI or an MPG EVP solution, then it's hard for you to take care of the road fillers. And a BGP road target must be very accurate, but here you don't deal with anything. This is also very great about ACI, which takes less networking. There's no port. Everything is tied to the object. So that's very easy. I believe that it is exactly the same environment and same thing that we face with the Cisco Blade system. You can create a foreign device and attach it to any server on the Blade and everything works fine. 

What other advice do I have?

I would rate Cisco ACI nine out of 10. I'm always trying to push customers to use Cisco solutions. When I'm talking to my clients or anyone else who is thinking about using Cisco solutions, I always say 10 out of 10, but I believe that there is some space for improvement.

Stable with good baseline functionalities but requires better flexibility
Pros and Cons
  • "The stability is quite good."
  • "Technical support needs to be more helpful. It's rare that you get a knowledgeable person."

What is our primary use case?

Primarily, what we like is the ability to do micro-segmentation. We have many different application endpoints, and one of the key use cases for us was to be able to classify the application endpoints into arbitrary buckets of different silos. We need to be able to ensure that different endpoints will go into, let's say, a production silo, versus a development silo, versus a test silo. That was one of the use cases.

The function above and beyond that is that you get things like automation as part of the SDN framework. Therefore, you get the data center overlay that is built automatically and provisioned automatically from the automation capability that's built-in.

What is most valuable?

The solution has all of the baseline functionalities for any sort of SDN capability. 

The stability is quite good.

The initial setup is straightforward.

What needs improvement?

One of the areas that need work is feature flexibility. If you want to do things like routing policies it's not cookie-cutter, however, you want to customize routing policies. It becomes a little bit more constrained due to the feature set, the routing policy feature set within ACI, doesn't allow for you to get very customized when it comes to, let's say, failover type scenarios. However, that's just an artifact of the product maturity. It's going to take some time before the product becomes mature and they have the ability to have more customized features enabled. At version 4.0, these features were not yet available. We ended up having to basically export the routing functionality, the more advanced routing functions, outside of ACI and just put it into the routing infrastructure around it.

The initial setup is not intuitive.

Technical support needs to be more helpful. It's rare that you get a knowledgeable person.

It would be nice for them to provide visibility at a cheaper price point. Visibility is something that everybody wants to achieve with their workload. One of the benefits of SDN is supposedly the ability to collect all that telemetry and correlate it to something that is actionable and meaningful. That's a key requirement, however, the bar is so high in terms of costs. In our environment, we opted out of it as it's so expensive, however, it would be nice, as, if you don't have visibility, then how do you properly segment your workload? The minute you start segmenting, you kind of cut off workload communication. If your goal is micro-segmentation and putting your workload into arbitrary silos, and if you don't have the visibility, then it will be very difficult to achieve. Therefore, if you don't have visibility and you want micro-segmentation and you don't want to pay, then ACI is not your solution.

For how long have I used the solution?

I've been using the solution for two years at this point.

What do I think about the stability of the solution?

The solution is stable. We don't have issues with it crashing or freezing.

What do I think about the scalability of the solution?

While supposedly it's scalable, the program is not. I don't have any data point that I can provide for scalability within ACI, as our environment is fairly small.

How are customer service and technical support?

Technical support is hit or miss. Sometimes you can open a ticket and you will not have to escalate it three or four different times before you get somebody that is competent. I would say that's 85% of the time, however, the other 15% of the time you get lucky and you get somebody that knows what they're talking about.

Which solution did I use previously and why did I switch?

I have some experience with VMware. I'd describe it as more intuitive and easier to configure, however, it's a different solution as it's software-based as opposed to ACI which is hardware-based. 

How was the initial setup?

The solution's initial setup is straightforward. It is not difficult. One other area that I would say is a negative is the way that they have their setup. It's not intuitive. It's very complicated and if you want to provision an interface or something like that and get that interface, it requires a bunch of steps that are very counter-intuitive. It's not user-friendly.

What's my experience with pricing, setup cost, and licensing?

The pricing could be a bit cheaper.

Which other solutions did I evaluate?

If I compare ACI to a VMware NSX-T type solution, I don't know if there's a differentiator there compared to NSX. I will say that NSX has much higher numbers of differentiation, as they have visibility into the workload at the hypervisor. Having used ACI, we were looking at solution sets that will give us specific capabilities beyond that. The value of NSX is it will give you the visibility component.

What other advice do I have?

The version that I was working on is a 40 version, however, the company is at a 50 version at this point.

If you are looking for a solution that will give you the ability to have really good visibility into your workload, how your workload performs and functions, ACI doesn't give you that level of granularity as compared to, for instance, a solution like VMware NSX. For them to provide visibility, you're going to have to spend a lot of money on Tetration, which is another solution that they try to force on you. If visibility is one of your key requirements, then you might want to rethink your data center SDN solution for ACI.

I'd rate the solution at a six out of ten.

Centrally-managed and high-performance solution for data centers, providing seamless communication between services, flexibility for future expansions, and efficient cost-saving capabilities
Pros and Cons
  • "The flexibility of adding new components with minimal impact on existing services running in the data center is a key benefit of this ACI-based solution."
  • "Its scalability and reliability capabilities should be enhanced."

What is our primary use case?

We deploy Cisco ACI within our customer's data centers, providing them with the capability to configure the software-defined network as per their defined requirements. This solution empowers customers to centrally monitor and control the network without the need for individual edge management. Moreover, it offers scalability, allowing for easy expansion in the future.

What is most valuable?

This solution facilitates seamless communication between various services and ensures future scalability with minimal configurations and operational effort. The cost savings for customers are notable, particularly in instances where adding ports or making operational adjustments is a straightforward process, requiring minimal resources. ACI stands out as a state-of-the-art, high-performance, and highly scalable solution.

What needs improvement?

Its scalability and reliability capabilities should be enhanced.

For how long have I used the solution?

We have been working with it for approximately eight years.

What do I think about the stability of the solution?

Occasionally, we encounter the need to reset certain programs due to bugs within one of the implemented data features. This requires performing upgrades approximately every six months to address and resolve these issues. I would rate its stability capability eight out of ten.

What do I think about the scalability of the solution?

While I acknowledge that the solution is scalable, there are occasional bugs and the need for upgrades or adjustments approximately every five years. We operate on multiple levels, with small, medium, and high scalability organizations. Typically, we opt for the highest scalable level during our implementations. I would rate its scalability at seven out of ten.

How are customer service and support?

I would rate its customer service and support nine out of ten.

How would you rate customer service and support?

Positive

What other advice do I have?

Overall, I would rate it eight out of ten.

A stable solution that enables micro-segmentation to secure servers
Pros and Cons
  • "Micro-segmentation is the solution’s most valuable feature."
  • "We faced some issues while configuring the microsegment."

What is our primary use case?

We use the solution’s microsegment for the security of the servers in the same VLAN.

What is most valuable?

Micro-segmentation is the solution’s most valuable feature.

What needs improvement?

We faced some issues while configuring the microsegment. 

The solution should provide a visibility tool for troubleshooting.

For how long have I used the solution?

I have been using the solution for five years.

What do I think about the stability of the solution?

The solution's stability is okay.

How are customer service and support?

When we contacted support for troubleshooting, the issue was escalated to the next level in four hours. However, the last time we had a problem, the support took a long time to investigate.

How was the initial setup?

The initial setup is complex because it is a software-defined network.

What other advice do I have?

I suggest that Cisco delete and add a new EPG. Overall, I rate the solution an eight out of ten.

Which deployment model are you using for this solution?

Application-driven with good automation and helpful support
Pros and Cons
  • "We get a full holistic view of the ecosystem."
  • "Compared to VMware, it needs more virtualization technologies."

What is our primary use case?

We help customers obtain, renew, and upgrade. This is a multi-cloud software-defined data center. If a customer is in banking, we can separate and secure data centers for multiple sites.

What is most valuable?

I really like the usage of the application. It offers a good focus on applications and has a driven policy model. It is capable of automation and application-driven. Customers can focus on the applications, and this benefits the end customers.

We really like the GUI and the visibility we get in on the dashboards. You get real-time details on performance. 

The DevOps teams can integrate their own software in ACI. 

We can monitor which areas are working well. 

It can be used with Kubernetes.

We get a full holistic view of the ecosystem. 

What needs improvement?

Ideally, if it could be more aligned as a unit, it would be useful.

Compared to VMware, it needs more virtualization technologies. It cannot match that right now based on the hardware boxes that we use. It could be more virtualized. There is less flexibility as they have less virtualization.

The contract management could be better.

It needs to include log files.

The GUI could be better. The solution be more user-friendly.

We've seen a lot of trends in companies moving towards AI and cloud capabilities. If it could really focus on this area, it would continue to be a very good product. It would improve the cost-benefit of the product in the long run. They need to integrate with multiple cloud platforms. Better integration and compatibility across the board, in fact, would make it a better product.

For how long have I used the solution?

I've used the solution for four to five years. The customers I work with use ACI.

What do I think about the stability of the solution?

I have found the stability to be good. I'd rate it nine out of ten. 

What do I think about the scalability of the solution?

The scalability is pretty good. You should have two of the spines altogether. Then the leaves can expand when you want to have more bandwidth or more throughput requirement.

If you need more computing power or networking power in the data center, then you have to add the leaves. Of course, if you need more throughput power, it's a bit different. For example, if one spine has the power of 4GBs, the two spines, which are combined, give the power of 8GBs, if you want more throughput, for example, 50GBs, you just go and add a couple of spines to it to commit to that sort of power. 

We tend to work with medium to large organizations.

I'd rate the scalability seven out of ten.

How are customer service and support?

Technical support has been good.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I haven't worked much with other solutions. I have worked with VMware NSX. It's similar, however, it is more flexible and is faster to set up.

How was the initial setup?

The initial setup isn't too complex, depending on the user's background. If a person is comfortable with Cisco products, it won't be too hard. You do have to use the command line, which makes it a tedious task. That said, you have more advantages with configuration capabilities. 

I'd rate the process eight or nine out of ten in terms of ease of setup. For the most part, it takes five to six steps.

It doesn't take too long to set up the entire product. It's easier than the other areas of the Cisco portfolio. Cisco is also making deployments easier to handle in general. It might take a few days since it is software-defined. 

On a high level, if the customer has a lot of devices, it might take two to three hours, and then you need to integrate everything. It shouldn't take more than 30 minutes after that to deploy and get the devices integrated. It's just working on it and reviewing tasks, which takes some time. It's an ongoing process.

What's my experience with pricing, setup cost, and licensing?

Cisco solutions are pretty pricy as you have to buy the AP controllers, leaves, spines, and hardware. I'd rate the pricing six out of ten in terms of affordability.

What other advice do I have?

We are resellers and consultants. We provide insights to clients regarding this product. We don't use the solution ourselves; we help the customer use it and realize its value. We're Cisco partners. 

We don't use a specific version of the product. Typically, we use the latest when it comes out.

I'd recommend the solution for users that have a traditional setup and need a dashboard. Many banks have complex data centers. They'd benefit from moving to this solution.

I would rate the solution nine out of ten.

The pricing factor is an issue. It's also not as good as VMware as it is not as virtualized. However, the Cisco portfolio is quite strong.

A stable solution that makes your network easy to manage
Pros and Cons
  • "The basic functionality that is the most useful is creating a virtual network on a physical device."
  • "Cisco SDN will only work with its own devices, so that's a downside."

What is our primary use case?

We use this solution to achieve a properly defined data center, so we basically use it for SDN. 

What is most valuable?

The basic functionality that is the most useful is creating a virtual network on a physical device. We use it for Software-Defined Networking where we have a centralized controller, and the rest of the switches are just for packing traffic. When you have a centralized controller, it's easy to manage.

What needs improvement?

The virtualization part of it is still all hardware-based. You have to buy the switches, and they have to be Cisco switches. You cannot roll the Software-Defined Network and network virtualization over onto any other product. For example, if I have a mix of Juniper and Cisco in my network, they are of the same physical fabric layer, but when I want to virtualize, it's quite difficult. You cannot do it. There are solutions like NSX that can sit pretty on any physical layer, but Cisco SDN will only work with its own devices, so that's a downside. They need to be able to achieve virtualization end-to-end with Cisco ACI.

For how long have I used the solution?

I have been using this product for over four years.

What do I think about the stability of the solution?

I rate the solution a nine and a half out of ten for stability. 

What do I think about the scalability of the solution?

You can scale the solution, but you cannot scale to other products. I rate the solution an eight out of ten for scalability. 

For backup you might want two people, but one person can handle all of the maintenance. Everything is managed centrally. This is a backend product, so not everyone knows they are using Cisco ACI. The organization I currently work for has over 10,000 employees, and practically everyone is involved in usage of the solution. 

How are customer service and support?

If you have the right license and premium support, the tech support is a nine out of ten.

How was the initial setup?

On a scale of one to ten, I would rate the initial setup as a nine. It was very easy. There are some external factors you need to connect, like cables. However, with the push of a button, in less than 15 minutes, you can roll out the basic Cisco configuration.

It's a graphic installation. You will see buttons: "Next," "Next," "Next." It's very easy to get up and running, just like setting up a phone. "Do you want to install this?" "Yes." "Do you want to enable this?" "Yes." "Do you want to configure this?" Unlike before where you had to configure Cisco switches one at a time, now you manage and configure it centrally, and you have a template to work with.

What about the implementation team?

Sometimes we handle the deployment ourselves, but for the current deployment we are rolling out, we have a system integrator. We have Cisco itself involved. 

What's my experience with pricing, setup cost, and licensing?

The good thing about Cisco is that you can trade in your old products to replace them with ACI. On a scale of one to ten, where one is inexpensive and ten is expensive, I would rate them a two. 

Which other solutions did I evaluate?

We considered VMware NSX, but some believe that VMware is vulnerable, so we stuck with Cisco. 

What other advice do I have?

I would 100% recommend Cisco ACI to other users. I would rate this solution as a ten out of ten.
