[Sandeep Bajaj]

Hi Team

Can you help me with designing of CUCM 12.5 on AWS?

Also if you have some useful links please provide it ?

Hi, I am just checking the release notes and it is not there anymore. Has Cisco ditched it?

[richb1971]

Yup ditched. Not an option anymore. Took TAC a while to confirm but its been removed now

[Chris Deren]

That's correct, AWS is no longer supported for Cisco collaboration applications.

Hey Sandeep,

did you manage to migrate the CUCM on VMware Cloud on AWS? What type of instance/specs did you have to resort to on the AWS side (instance processor type, RAM, EBS VOlume size and type etc? and what CUCM version are you running on the ESXi in VMware Cloud on AWS?

Thanks in advance for any pointers.

Kind regards,

A.

Check out this Cisco Live session which I found very informative on this topic, it has many details including design aspects:

BU chiming in...

There is no "UC on public cloud IaaS support" at this time.  See clarifications here: https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/virtualization/virtualization-software-requirements.html#unsupported_infrastructure

A few applications briefly had support for "VMware Cloud on AWS", but this support has been discontinued due to zero customer uptake and strategy change.  There may be a few leftover webinars still aging out, and UCCX/E may still be taking down some of their old docs, but for UCM, Unity Connection, IMP all docs have been taken down or updated to reflect no support.   My old webinars mentioning this have either had slides updated or have been taken down. 

A few additional clarifications:

• "VMware Cloud on AWS" is NOT the same thing as "AWS". 
• When most people say "AWS" they really mean the Amazon-sold AWS EC2 service.  This has never been supported for on-premises apps, and no plans to at this time.  
• "VMware Cloud on AWS" is totally different, it is VMware-sold service based on "VMware Cloud Foundation" stack.   Again, this was briefly permitted for a few apps, but with zero customer adoption and has been discontinued.  There are MANY other options based on "VMware Cloud Foundation" (there's one with Microsoft, one with Google, one with Dell EMC vxRail, etc.) but those are not supported either.

Business drivers for IaaS are typically "I want to move infra to cloud while retaining control of apps with familiar enduser/admin experience".   UCM Cloud (or HCS with a Flex Managed partner) can address those drivers, subject to how the partner has structured their offer.

Why does Cisco have multiple cloud options?   Same reason why Cisco has multiple on-premises options ... Cisco must address different customer types with very different requirements/expectations.  Which offer is "right/best" is a multi-factor decision, so best to have that discussion with partner/Cisco account team who understands customer business context (a good consultative seller will ahead of time have figured out customer's business context and filtered options to the right one before delving into portfolio).

Hope that helps!

With respect to "zero customer adoption" - I think the option of VMWare on AWS was not available as a supported solution for long enough for enterprises to evaluate whether or not it was a suitable fit.  We are just now moving to 12.5. The TCO of various hosted options has not so far come down to match the "do it ourselves" cost, but as more data center compute services move to the public cloud AWS / Azure / etc, it makes consideration of building UC in the cloud more attractive.  There is no one-size fits all approach.

[Dalton-Covene]

Call Manager (CUCM) and other Cisco UC Applications are not currently supported on VMware Cloud on AWS, Azure VMware Solution, Google Cloud VMware Engine, etc.  This includes version 14 as of 12/15/22. 

Please see below for reference. 

Cisco Collaboration Infrastructure

Cisco Collaboration applications do not support any 3rd-party public cloud infrastructure as a service (IaaS) offer. Including but not limited to:

• Any 3rd-party public cloud offers based on VMware Cloud Foundation (e.g. VMware Cloud on AWS, Azure VMware Solution, Google Cloud VMware Engine and others are not supported).
• Any 3rd-party public cloud offers based on non-VMware technology (e.g. Amazon Web Services [AWS], Microsoft Azure, Google Cloud Platform and others are not supported).
• Any on-premises "hybrid cloud" extensions of 3rd-party public cloud infrastructure (e.g. VMware Cloud on Dell EMC VxRail, Amazon AWS Outposts, Microsoft Azure Stack, GKE On-prem and others are not supported).

[Roger Kallberg]

Why are you posting this on a years old post, with from what I can tell no new information than what others has already given?

[Dalton-Covene]

@Roger Kallberg - Because customers are still asking this question sir. 

As there is no mention of version 14 in any other posts/replies, this seems like new information specific to v14, from what I can tell. 

Perhaps the comments should be closed if we don't want to allow replies on a specific topic, rather than questioning folks who are simply trying to help others? 

[Roger Kallberg]

Fair point.
