Architecture review
We map the deployed environment, cloud and on-premises: network paths, routing, DNS, identity and dependencies. The review shows what breaks under load, failure or change, and sets out a target architecture with a migration path in safe, ordered steps.
What you get
- A runtime map of network paths, routing, firewall and segmentation rules, DNS, and identity and access flows, built from the deployed state
- A failure mode analysis: where the environment breaks and under which conditions
- A dependency and coupling review, including single points of failure
- A target architecture with explicit trade-offs
- A migration path in ordered steps, each one safe to stop at
- Written findings in priority order, with risk, effort and expected outcome for every item
How it works
-
01
Map the deployed environment
We read network paths, routing, firewall and segmentation rules, DNS, and identity and access flows from the deployed state, across cloud and on-premises.
-
02
Analyse failure modes
We find the conditions that break the environment: load, a zone or site outage, a certificate or secret rotation, a routine change, or a failed dependency.
-
03
Review dependencies
We list tight couplings, forgotten shared services, stale links between environments and single points of failure.
-
04
Design the target architecture
We set out a target architecture with explicit trade-offs: what to keep, what to replace and what to leave alone.
-
05
Plan the migration
We order the steps from today's setup to the target so that each one is safe to stop at, with no big-bang cutover.
Problems it solves
-
ProblemNobody fully knows how the environment is wired any more, so changes get put off because their effect is unknown.
SolutionWe map network paths, routing, firewall and segmentation rules, DNS, and identity and access flows from the deployed state. The effect of a change is then visible before it is made.
-
ProblemHidden single points of failure in DNS, identity or egress go unnoticed until one of them causes an outage.
SolutionWe analyse what breaks under load, in a zone or site outage, during a certificate or secret rotation, or when a dependency goes down. Each weak point is listed with its risk.
-
ProblemLeaked public endpoints expose internal services, and overlapping address spaces collide as soon as two environments need to connect.
SolutionWe check routes, segmentation rules and public endpoints across environments. Asymmetric routes, exposed endpoints, dead links and address overlaps are listed with the change that fixes each.
-
ProblemForgotten resources are still billed every month, patched and backed up, though nothing uses them.
SolutionWe review dependencies and coupling to find forgotten resources, shared services and stale links between environments, so each one can be removed or given an owner.
What it covers
- Runtime map built from the deployed state
- Network paths, routing and DNS
- Firewall and segmentation rules
- Identity and access flows
- Failure modes under load, outage and change
- Dependencies and single points of failure
- Target architecture with explicit trade-offs
- Migration path in steps that are each safe to stop at
- Azure, AWS, VMware / VCD and on-premises
Typical engagements run 3–10 days, depending on the size of the environment and how much access is available on day one. A focused review of a single subsystem takes less time; full multi-environment mapping with hands-on remediation takes longer.
