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.

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?
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.

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.
Which deployment model are you using for this solution?
On-premises

Enables centralized management, enhances network efficiency, and provides good technical support
Pros and Cons
- "PBR has been beneficial for network efficiency."
- "The GUI is not easy to use."
What is our primary use case?
The solution helps with business continuity.
What is most valuable?
Centralized management is valuable. PBR has been beneficial for network efficiency. It helps redirect the traffic to a node that is not necessarily a gateway.
What needs improvement?
The GUI is not easy to use. It must be made simple and convenient to use.
For how long have I used the solution?
I have been using the solution for ten years.
What do I think about the stability of the solution?
I have not faced any issues with performance or stability.
What do I think about the scalability of the solution?
The tool is scalable. It can adapt to the growing needs of the business.
How are customer service and support?
We contact the support team when we face any issues.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup is straightforward. The deployment is centrally provisioned. The initial setup might take a couple of days. The deployment depends on the scale and customer requirements. We need one engineer for the deployment. The maintenance requires some skill development.
What's my experience with pricing, setup cost, and licensing?
The product is not cheap. It is usually expensive. However, the solution’s local presence and technical support sometimes make customers prefer it.
What other advice do I have?
We see tangible benefits of policy-driven automation in a modern scale environment where frequent changes are required. However, the features and benefits are almost negligible for a relatively smaller and static environment. The vendor's local presence and the support provided are the main reasons customers choose Cisco ACI. I will recommend the product to others. We must ensure that the use case is well-defined to get the benefit and ROI from the product. Overall, I rate the tool an 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?
Hybrid Cloud

Software Solutions Architect at NTT Ltd.
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.
Which deployment model are you using for this solution?

Network Consultant at Telcoset
Fabric can be managed from a single point; serial numbers can all be registered with scripts
Pros and Cons
- "Configures from a single point and commands don't need to be configured on the spine and leaf side."
- "There were issues when upgrading venues and registering devices."
What is our primary use case?
Our primary use case is project-based. We deploy and configure upgraded ACIs, registered spines and leaves, and deliver projects to our customers. I'm a network consultant and we are gold partners of Cisco.
What is most valuable?
The solution is valuable because it configures from a single point, from APs, and also all routers. Commands don't need to be configured on the spine and leaf side. You can control and manage the fabric from a single point. If you have serial numbers for your devices, they can all be registered with scripts. As a network engineer, you can configure and manage the fabric very easily. From the CLI side, it's really easy to configure from the GUI.
What needs improvement?
I faced issues when upgrading venues and registering devices. For example, in some cases, you have to reinstall the AP from scratch. We tried that and were then unable to register devices. From the network engineering perspective, it's hard to configure from the GUI. We tried to adapt but it was difficult. You have to add AP numbers for validations.
What do I think about the stability of the solution?
From an operational perspective, I think if you configure the fabric correctly, it's stable.
What do I think about the scalability of the solution?
The solution is scalable; you can have multi-site scenarios.
How are customer service and support?
I have a good relationship with the technical support team, they are helpful.
How was the initial setup?
Because I have a system engineering background and I have MCSA and MCSE certification from Microsoft, the setup is very simple. The largest deployment I was involved in had 300 devices.
What's my experience with pricing, setup cost, and licensing?
This is an expensive solution, but it's high quality. I have experience with Huawei devices and Nokia. Huawei had many issues with bugs and I had hardware issues with Nokia. Cisco is the highest quality.
What other advice do I have?
I rate this solution eight out of 10.
