If you have your current CMDB CIs mapped to Apps, estimation of like-for-like TCO in cloud is usually a straight forward exercise. On top of that, one has to add a fixed cost for certain Foundations elements. As the cloud adoption scales, this fixed cost diminishes as a % of cloud TCO.

The main challenges we faced were:
- Estimating Costs
- Managing Security
- Training

Finding the dev ops skill to tackle things like security, availability, monitoring, at a cost that is minimized based on your ingress, egress, and storage.

1. Application architecture is not "cloud-ready". Apps need to abstracted from infrastructure and have circuit breakers to eliminate internal dependencies.
2. Operations skills necessary to manage cloud based workloads on metered infrastructure.
3. Owning increased and more complex security requirements.
4. Dynamic data management to reduce copies of data - to manage cloud storage costs

Migrating legacy code without refactoring becomes very complex, and even counter productive at times. Hence it is essential to have good cloud architects who can drive this adoption. Then of course there is always a confusion on which cloud provider to move to, how do you manage security, etc

One is understanding Microsoft product licensing impacts by infrastructure choice.

Another is understanding their role in shared responsibilities, for instance scope 2 emissions caused by compute choices or security & compliance items.

Data & skills gravity.

Understanding how much it will cost.

There is a perception that moving to the cloud is ‘always’ cheaper. But that is far from the truth.

Moving to the cloud is ‘often’ cheaper. But depending on usage, workloads, etc., it can in fact be much more expensive. And for those firms that didn’t consider the costs, it is a rude awakening.
