Provides scalability, ease of migration for future DC moves, multi-tenancy and programmability
Cisco's MSO (Multi-Site Orchestrator) or NDO has room for improvement. Cisco monitors ACI through a product called NDI. I find it very frustrating that Cisco has multiple monitoring platforms. It has DNAC for monitoring Cisco NX-OS, campus switches, and any other routers and switches you would have in the environment. That same thing does not work for Cisco ACI monitoring. MEraki cloudbasd platform for Meraki which will get extended to Campus monitoring, to be honest Cisco never got Monitoring 100% right from days of CiscoWorks to Prime to current platforms. To monitor and manage Cisco ACI, you need to have another platform called NDI and Cisco Dashboard Insights. What frustrates me about Cisco is that it never has a central, single pane of glass platform for all its solutions. It has one thing for Cisco ACI and another thing for campus switches. I would really appreciate it if Cisco came up with something centralized to monitor everything. I haven't thought about anything since the Cisco NDO is quite advanced, and you can deploy your cloud networking through it. I don't know how many people use it. I might explore it as my cloud orchestration tool in the future. We do a lot of cloud automation using our scripts like TerraForm, but I would like to see people using NDO more. We could have more case studies on how many people use NDO for their cloud orchestration. That might be a much easier journey for people when they move from an on-premises data center into a cloud and move from one cloud to another cloud. That is where I personally see an orchestrator being effectively used for multiple deployments.

Visual traffic interface aids in network micro-segmentation while a streamlined update option enhances process efficiency
The strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies. We can write rules that can be embedded into the IP table, making it easy to handle. Illumio enables us to see network flows, traffic sources, and destinations. The policy generation and enforcement capabilities are valuable, allowing for selective enforcement. Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Cisco technical support is great."
"I especially like the host-based routing feature of Cisco ACI because it's straightforward to do it on different data centers. Another valuable feature of Cisco ACI is that its management controller works very well with no issues."
"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."
"This product improved the way our company functions by enabling us to establish our goal of moving to a zero-trust model. That's how Cisco ACI helps us the most."
"PBR has been beneficial for network efficiency."
"The most valuable features include microsegmentation, L3 Out features, and the common tenant and tenancy model."
"The initial setup was pretty straightforward. We just moved from one platform to another."
"Cisco ACI was the first product in the market, offering stability with a significant install base."
"I would recommend Illumio to all sizes of companies."
"The solution helps to maintain logs and monitor activities. It also helps us with access management. The tool helps us to secure organizational data that include files."
"The most valuable feature of Illumio Adaptive Security Platform is monitoring. When I have no requirement from the other application, I can use the web block traffic to build."
"The Explorer allows you to know the traffic between source and destination."
"The strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies."
"The flexibility of the solution is its most valuable feature."
"Customer support is excellent."
"The features that I have found most useful is the ability to centralize all the rules and then distribute them across various locations. However, I've encountered challenges related to tagging policies, which can be complex to devise. It's a matter that requires careful consideration and stakeholder involvement before implementing such policies."
 

Cons

"Customer support for ACI needs improvement. Many customers prefer HPE because their internal support is different and easier to integrate with existing networks. This lack of awareness of ACI's capabilities makes customers stick to traditional networking."
"The tool's initial deployment is complex and takes five hours to complete."
"Cisco should provide more examples of code in their website. Something that other people can use. There is a great place in the development area."
"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."
"I would like to see a lot more integrations with the rest of the Cisco portfolio."
"We would like to have faster services and problem monitoring for our customers."
"Its graphical user interface (GUI) is not as user-friendly as it could be."
"Compared to VMware, it needs more virtualization technologies."
"I would like to see better data security in the product."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades. This would be more helpful to streamline processes."
"Some of the features that can be improved is offer additional guidance on creating an effective and risk-free tagging policy would be highly beneficial."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"I have not had the chance to experiment deeply with it."
"The product’s agents don't work very well in OT environments."
 

Pricing and Cost Advice

"Cisco ACI costs depend on how many sites you have. One simple site with a simple installation, including two leaves, two spines, and some fibers, would cost $200,000 to $300,000 for the licenses. The solution is a bit expensive, but it's a good investment if you want your data centers to work without interruption."
"There are no additional costs. We only have to pay for a support contract apart from the license."
"Cisco is much more expensive than other vendors, especially when it comes to the licensing."
"The licensing cost for ACI is expensive - I would rate its price 2.5 out of five."
"Cisco ACI is more expensive than Juniper, however, ACI is not the most expensive option."
"The price could be improved. It is expensive, but then again, it is Cisco. The price is worth what you pay for."
"Price is always an issue."
"It saves time and resources."
"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
