Why Yemberzal
Large banks have whole teams making sure nothing in their cloud is left to chance. We bring that standard to firms that don't.
One cloud, known in depth: its pricing models, its resilience patterns and its migration tooling.
The architect who scopes the work does the work. No account managers, and no hand-offs to junior staff.
Every diagnostic is fixed-fee and priced on this site. You know the cost before we start.
We work the way a regulated firm needs work done in its accounts.
Industry data
One figure for each problem we work on. Every source is linked.
Why trust the work
Nearly three decades in IT and nearly a decade in cloud, inside tightly regulated organisations including HSBC and Barclays.
In banking, a misconfiguration isn't a bug. It's a regulatory event. I've spent my career working to that standard.

For AWS accounts spending £2,500 or more a month. How it works
How an engagement works
Four steps. You can stop after any of them, and you'll know what the next one costs before you take it.
Step 01
An honest view of whether we can help, and which diagnostic fits. If we can’t help, we’ll say so.
Step 02
An audit or assessment, with a written report you keep whatever you decide next.
Step 03 · Optional
A fixed-fee sprint or project, quoted from the diagnostic's findings. Or take the report and do it yourselves.
Step 04
A monthly retainer that keeps savings and resilience from drifting back.
Insights
