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

"The efficiency in terms of the data center latency has been reduced by around 20-30%. Our applications function a lot better. We get a lot of intuitive data to know how our application stack is performing."
"We had different networks and combined them with ACI so we could have the control of one controller-based network. Also, everything is combined now."
"I have found the SDN features to be the most valuable."
"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."
"Cisco technical support is great."
"It offers multitenancy. The opportunity to install it on the same platform with a huge amount of customers."
"The integration with vCenter means that when I create something on the network, it only has to happen one time instead of many times for our many virtual hosts."
"The most valuable features of Cisco ACI are micro-segmentation, the VXLAN, and the ACI flattening services."
"It has helped us to understand internal network visibility and firewall policy implementation. We use the product to simplify firewall policy implementation."
"The flexibility of the solution is its most valuable feature."
"The dependency map is most valuable feature."
"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 tool helps with my company's security posture."
"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."
"Customer support is excellent."
 

Cons

"The additional features I would like to see included in the next releases are support for our policy-based routing. There are endpoint issues that are there now in the code. Hopefully, these will get fixed in the future code."
"From my point of view, troubleshooting issues relating to ACI can be a little bit complicated to perform."
"The CLI needs to be improved."
"More how-to videos and instructional information is required."
"The error messages should be improved. Sometimes we want to remove an error message so we acknowledge an error and we would then like to remove it but there's no real way of doing that. If we need to do it, we need to open a tech case. That could use improvement."
"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."
"The initial setup was not straightforward. We adopted an agile strategy, starting small and expanding to multiple data centers."
"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."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"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. This would be more helpful to streamline processes."
"I have not had the chance to experiment deeply with it."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"The product’s agents don't work very well in OT environments."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades."
"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."
 

Pricing and Cost Advice

"Pricing for Cisco ACI could be expensive if you're not a gold partner. If you're a gold partner, you'll get reasonable pricing, but to become a gold partner, you must cross several layers. For example, at least twenty engineers within your organization have to be certified, with each certification priced at £2,000 minimum, so this would make some companies think twice about the product. If you're going for Aruba and Juniper products, on the other hand, you can quickly get the partner status, and you can start selling the product. As a gold partner, you can get up to seventy percent discount on Cisco ACI, for example, while an ordinary partner gets ten percent off. Cisco ACI is expensive for both customers and partners, but I'm rating pricing for the product as four out of five because even if the price is costly, you get a lot of benefits from the product. Cisco ACI isn't the best, price-wise, but it's still a good solution. If you're in a small organization, you may be unable to afford it. Cisco ACI is best for enterprises but not SMBs because Cisco ACI and its required resources are expensive."
"It's expensive but the product is very good. I have never found another partner like Cisco with a solution like this and with great support."
"The pricing, including both hardware and licenses, is reasonable."
"The thing that I like the most from Cisco is the support and all the documentation that they have. We do have to pay for it though."
"The product is not cheap."
"A big company can automate it themselves or spend a lot of money and buy it."
"The pricing is pretty good for new technology."
"We bought a package for hardware, software, and support. At that time, Cisco was simply selling that package to distributors, then we opted for it directly."
"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
