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

"Configures from a single point and commands don't need to be configured on the spine and leaf side."
"It offers multitenancy. The opportunity to install it on the same platform with a huge amount of customers."
"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."
"We can support policy based on our intent, then that gets rendered into the policy that we will be using for Fabric."
"Cisco ACI's multi-tenancy has been most beneficial for our network management."
"The initial setup was trivially simple and easy. It builds itself because it is automation. You don't have to do too much."
"PBR has been beneficial for network efficiency."
"Micro-segmentation is the solution’s most valuable feature."
"It has helped us to understand internal network visibility and firewall policy implementation. We use the product to simplify firewall policy implementation."
"The Explorer allows you to know the traffic between source and destination."
"The solution is easy to use."
"Customer support is excellent."
"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 flexibility of the solution is its most valuable feature."
"The dependency map is most valuable feature."
"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

"It would be great if ACI would include the next generation firewall feature."
"So far we've had very few issues, a couple of routing things that were glitches within ACI."
"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."
"Cisco ACI is a highly complex solution. The initial deployment is just a few clicks, but understanding how an ACI works and interacts with routing, switching, and virtualization takes a lot of knowledge. The interface isn't necessarily hard to use, but the technology is complicated. If you want to understand how it works and how to configure it, you should study hard."
"The learning curve is long. It's very difficult to learn Cisco ACI. As a result, our customers usually have difficulty working with this solution."
"Because this is new technology, which requires a different way of thinking, it can be hard to understand. Therefore, I would like more documentation or education."
"The challenging thing about Cisco ACI was we had to put a lot of effort into providing the customer the full picture, new standards, and new technology that they had to use. This was more challenging than deploying the product."
"We're still in the process of doing the migration. We haven't migrated completely all of our applications out of our legacy into it yet. It was challenging at first, but getting easier now that we're starting to get into it."
"It requires a low-level re-architecting of 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."
"The product’s agents don't work very well in OT environments."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"I have not had the chance to experiment deeply with it."
"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."
"We need more details on areas where there is an error or a traffic blockage. I would like the tool to offer a more detailed view."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
 

Pricing and Cost Advice

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing an eight out of ten."
"Cisco is much more expensive than other vendors, especially when it comes to the licensing."
"We have saved time on the provisioning and configuration."
"Cisco ACI is more expensive than Juniper, however, ACI is not the most expensive option."
"I don't believe there is any licensing required."
"The product is not cheap."
"The pricing, including both hardware and licenses, is reasonable."
"It is quite expensive. It is not at all on the cheap or medium side."
"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."
