AWS recently announced enhanced custom event buses for Amazon EventBridge, allowing organizations to share a centralized bus across accounts with ordered delivery, simplified subscriber management, event replay, content-based deduplication, and a new publisher/subscriber-based pricing model.

Why it matters
The cloud conversation moved from migrate everything to deciding what goes where. That maturity is a good sign, but it also makes the discussion harder: there is no single answer any more, it has to be argued case by case, and very few people have the numbers to do it.
I separate what moves for cost from what moves for capability. Migrating to save money almost never works; migrating to be able to do something you could not do before does. When the argument is only savings, it is worth checking the numbers again because they are usually incomplete.
What usually goes wrong
The mistake that repeats is not sizing egress traffic. The numbers get done on compute and storage, which are the visible ones, and the surprise arrives with data transfer. It is the line on the bill I have most often seen dismantle a well-built business case.
What to watch
- Three-year total cost with real growth, not the first-year promotion.
- How hard it would be to leave or move a piece to another provider, which is future negotiating power.
- Who sees the bill and in what detail: with no owner for the spend, the spend grows on its own.
How I read this entry
If this fed into an infrastructure decision, I would ask for the three-year total cost with real growth built in, not year one with the entry discount. Most cloud surprises live in year two, when the discount ends and the volume has already gone up.
