What are the top cloud computing trends to look out for in 2023?

Cost Benefit Analysis.  As the economy slows, CFO's are going to be asking for verification that the proposed savings by going to the cloud were realized.  In my experience, it was very hard to predict the costs, because they vary greatly as you scale up or down the size of the platform.  I think 2023 will cause a lot of groups to "right-size", by looking at their utilization, and realize the engineers were a bit optimistic on how many people would be using their Cloud, and will be able to scale it down and reduce costs.

Organisation will join the race for cloud migration and will expedite the process. Most of the on-prem load will be shifted to cloud along with cost optimisation strategy.

Containers
I think containers will become significantly more prevalent vs FaaS or VMs in the next year
Many operations are already containerized behind the scenes, but I expect there will be a larger focus on it 

Data security and governance 
With many data breaches or leaks I expect this to receive a lot of attention

Sustainability and green cloud
