This page is structured as a working reference architecture document for healthcare cloud - the kind we'd present in your next architecture review. If the architecture is right, the engagement reasoning is obvious.
Identity is the first design surface in any healthcare cloud architecture because every subsequent layer depends on it. The reference architecture we defend:
This layer is where most healthcare cloud architecture audits surface their first material findings. We treat identity as architecture, not as IT hygiene.
Standing access is the exception, not the default.
short-lived credentials, workload identity federation (no long-lived service account keys), credential rotation governance.
Encryption-at-rest with customer-managed keys (CMK) for any storage holding PHI. Provider-managed encryption is insufficient evidence in regulatory contexts.
Key management hardened: dedicated KMS keys per workload sensitivity tier, rotation policies enforced, key access audited.
PHI tagging at the resource layer so cost, access, and lineage tooling can reason about PHI as a first-class attribute.
Data residency designed deliberately - single-region for residency-sensitive workloads, multi-region for resilience, with the trade-off documented for the compliance team.
Backup, retention, and immutability policies matching HIPAA retention requirements and your specific data governance posture. Backups themselves treated as PHI when applicable.
Security Rule and Privacy Rule controls mapped to specific architectural components, with evidence collection automated.
designed in, not retrofitted.
control evidence flowing automatically into a SOC 2 collection point (Drata, Vanta, Secureframe, or self-hosted).
BAA execution at the platform layer, with downstream BAAs (cloud provider, managed services, third-party SaaS) cataloged and current.
AWS Config, Azure Policy, GCP Organization Policy, plus third-party CSPM (Wiz, Orca, Lacework) where the workload sensitivity justifies it.
Incident response runbooks for PHI exposure, regulatory reporting events, and security incidents - documented, exercised, audit-ready.
metrics, traces, logs, security events. Centralized SIEM for security-sensitive signals.
Patient portal availability, scheduling availability, telehealth latency. SLO-driven on-call.
Severity classification, blameless postmortems, incident metrics tracked over time.
which run distinctively cost-sensitive at scale. Reserved-instance / savings-plan / committed-use discipline, idle resource reaping, intelligent tiering, multi-cloud cost comparability.
so the AI initiative, the EHR adjacency platform, and the patient portal each carry their own cost story.
Current-state assessment. We catalog your cloud estate - accounts, networks, workloads, PHI surface, compliance posture, operational maturity.
Gap analysis. We compare current state to the reference architecture layer by layer. Gaps are scored by HIPAA risk, operational risk, and cost.
Target architecture and roadmap. Layered remediation roadmap with engineering effort, sequencing, and the right partner mix (Logiciel, internal, alternative vendors) for each remediation.
Executive readout. Formal readout to your CIO, CISO, or VP Cloud Architecture with the artifact your leadership team can use to fund the remediation work.
The math doesn't work. AI reliability is a platform problem with a real engineering specialization behind it - not a side project a feature engineer absorbs.
The diagnostic engagement above. Most common starting point.
Logiciel architects design and lead the implementation of the target architecture alongside your cloud engineering organization.
A senior Logiciel cloud architect serves as your fractional architecture leader, typically 8–16 hours per week, for multi-year programs.



Teams that needed to ship fast, and did. Here's what partnering with Logiciel felt like from the inside.
Cloud architecture services in healthcare cover the design, assessment, and implementation of cloud platforms that support clinical, operational, financial, and AI workloads under HIPAA, HITRUST, SOC 2, and applicable state regulations. The work spans identity and IAM design, network segmentation, data and storage architecture, workload architecture (containers, serverless, managed services), security and compliance posture, and the operations layer that keeps the architecture defensible over time.
The right answer is workload-specific and shaped by three factors: regulatory and vendor-risk requirements (do you need to demonstrate cloud-vendor neutrality to regulators or enterprise customers), legacy integration depth (how much on-prem clinical infrastructure has to coexist with cloud workloads), and workload economics (do specific workloads run materially better on a specific cloud). Most US healthcare organizations end up hybrid + multi-cloud not by design but by accumulation; the architecture review redesigns deliberately.
PHI handling is designed at every layer - identity (access logging, JIT elevation), network (private connectivity, segmentation), data (customer-managed encryption keys, residency, retention), workload (BAA-eligible services only, accountability for control gaps in managed services), and security (HIPAA-aligned posture, evidence collection automated). PHI is treated as a first-class architectural attribute, not as a compliance retrofit.
AWS, Microsoft Azure, Google Cloud, Oracle Cloud Infrastructure (where workloads benefit), and on-prem / private cloud environments where required. Logiciel's healthcare cloud practice is vendor-neutral - we design against the right architecture and recommend a provider mix based on workload requirements, existing investments, and BAA posture.
The 4-week architecture review produces a prioritized roadmap with effort estimates. Remediation programs typically run 6–18 months for material architectural gaps and ongoing for incremental improvement. The pace is determined by organizational change capacity and the cloud estate scale, not by Logiciel's capacity.
The 4-week architecture review is a fixed-price engagement. Architecture Design & Implementation Lead engagements run on a multi-quarter engagement model scaled to scope. Fractional Chief Cloud Architect engagements run on quarterly retainer. The review produces specific numbers for your context.
Yes - that's the design. Most engagements partner with an existing cloud engineering organization. We design for collaboration, knowledge transfer, and ongoing internal operation. Several long-term healthcare engagements have evolved into a smaller partnership footprint as the internal team grew into the architectural maturity the engagement produced.
The architecture review is the smallest credible engagement that produces a defensible target architecture and a prioritized remediation roadmap. Most healthcare cloud leaders use the artifact to align the executive team and the security/compliance function on a multi-quarter remediation program.
