Architecture Review & Overhaul

Across Azure · AWS · VMware / VCD · on-prem

Who it's for

Systems where nobody fully understands how things are wired anymore. Frequent outages, unclear ownership, changes that feel risky every time — especially where cloud and on-prem have been stitched together over the years. The environment grew in pieces, each one made sense on its own, and now it's a pile of implicit assumptions nobody wants to touch.

What you actually get

• Real runtime map Actual network paths, routing, firewall and segmentation rules, DNS, identity and access flows — drawn from what's deployed, not from what's in the wiki.
• Failure mode analysis Where the environment breaks under load, during a zone or site outage, during a certificate or secret rotation, during a routine change, or when a specific dependency goes down.
• Dependency & coupling review Hidden tight couplings, forgotten shared services, stale links between environments, and single points of failure nobody's noticed yet.
• Target architecture A cleaner design with explicit trade-offs — what to keep, what to replace, what to leave alone. Decided on merit, not on current fashion.
• Migration path Ordered steps from today to target, each one safe to stop at. No big-bang cutovers, no weekend heroics.
• Written findings Prioritized report you can hand to your team: risk, effort, and expected outcome for every item.

Typical findings

Every engagement is different, but these show up almost every time. Most of them don't show up in monitoring until it's too late.

• Unused or forgotten resources Still billing monthly, still in scope for patching, still in someone's backup policy.
• Broken or overly permissive access paths Long-lived credentials, overly wide firewall rules, stale role assignments, service accounts nobody owns.
• Hidden single points of failure Usually in DNS, identity, or egress — the parts teams rarely think about until they fail.
• Misconfigured networking Asymmetric routes, leaked public endpoints, dead links between environments, overlapping address spaces waiting to collide.
• Backups that have never been restored They exist, they run green — nobody has actually recovered from them end-to-end.

What usually comes out of this

What you can reasonably expect from a full review:

• 20–40% of infrastructure spend identified as waste or oversizing Idle resources, dev environments that outlived their project, SKUs chosen for a peak that never comes.
• 1–3 critical failure points nobody knew about The kind of thing that would have caused a real outage in the next 6–12 months.
• Clear ownership across services and environments Who owns what, who gets paged, and what "owned" actually means for each component.
• Lower deployment risk Changes stop feeling scary because the blast radius is visible before you press the button.
• A target architecture your team can actually execute against Concrete enough to start tomorrow, flexible enough to survive real-world constraints.
