Cisco 4000 Series Integrated Services Routers (ISR 4000) vs Cisco SD-WAN

• Easy to use, simple to operate, highly predictable. IOS/IOS-XE is well known and there is a virtually limitless pool of engineers who know this platform and if not having direct experience, can apply knowledge from other IOS/IOS-XE with very little adjustment.
• Extremely flexible due to wide variety of interfaces. NIM and SM-X provide a great deal options: TDM, E&M, FXO, FXS, switches and servers are all options.
• Robust IP feature set: Routing protocols, NBAR, Netflow, QoS, DMVPN. This large IP feature set gives us the ISR makes it a highly re-usable router, capable in many different use cases.

• Super expensive to purchase and maintain licensing for
• Even with a big player like Cisco you get bugs in the software but hey, at least they're quick to fix them
• Sometimes you do feel like guinea pigs testing out beta software

• The minimum subscription time is three years, which makes the initial investment of the projects more expensive.
• The types of subscriptions that determine the accumulated bandwidth of the transport links generate a limitation to the additional solution that the hardware supports.
• Access to the Vmanage administration console must be from a previously established IP address, which removes flexibility of access to the cloud.

• We have had several times where we purchased assets and needed to add a remote site quickly for new staff to work. This is very quick to spin up and provides agility to business demands
• Allows for agility to failover network access when primary Internet services fail. We have near 100% uptime due to the ISR configuration we use. Even in the most remote locations.
• Since we adopted Cisco 4000 Series Integrated Services Routers (ISR 4000) as our de facto WAN hardware, we have cookie-cuttered our WAN infrastructure, which makes it easy to manage, upgrade, and alter with minimal impact to users and IT.

• Managing to use business applications efficiently causes us to get more value from our cloud subscriptions
• Able to use streaming services improved employees' morale and increased their performance
• Able to combine multiple connections, helped reduce costs, and prevented us from investing in only the most expensive WAN supplier
• Instead of relying on one supplier when one connection was down, we managed to carry on with another broadband solution
