Technology Architecture & Platform Standards
Technology architecture defines platforms, cloud landing zones, engineering standards, and resilience patterns that scale securely. Build target technology landscapes executives fund.
Executive Summary. Technology architecture translates business and application requirements into platform choices, cloud landing zones, network topologies, middleware standards, and engineering practices. Without it, teams reinvent infrastructure, cloud costs sprawl, and security controls fragment. This guide covers target technology landscapes, reference architectures for hybrid and multi-cloud, platform engineering, and lifecycle governance. Larkinized LLC helps organizations move from ticket-driven infrastructure to paved-road platforms that accelerate delivery while maintaining compliance.
Scope of Technology Architecture
Technology architecture spans compute, storage, network, middleware, identity, observability, and engineering toolchains—not only hardware diagrams.
It sets standards consumed by solution teams: approved services, configuration baselines, deployment patterns, and exception processes.
Technology architects partner with security, finops, and SRE functions; EA provides portfolio context and governance forums.
Success is measured by adoption of paved roads and reduction of snowflake environments.
Target Technology Landscape
Define platform domains: public cloud accounts/subscriptions, private data centers, edge, SaaS integration hubs, and shared services (DNS, PKI, backup).
Document approved technology stacks per application tier with sunset dates for legacy platforms.
Hybrid strategies articulate workload placement criteria—latency, data residency, cost, skill availability.
Roadmaps align platform upgrades with application migration waves to avoid double migrations.
Hybrid Target Landscape
Workloads placed across cloud, colo, and SaaS per placement criteria matrix with shared security and observability plane.
Cloud Landing Zone Architecture
Landing zones provide account vending, network segmentation, IAM baselines, logging, and guardrails before application teams deploy.
Implement policy-as-code (SCPs, Azure Policy, OPA) to prevent public exposure and unapproved regions.
Multi-account/subscription models isolate production, non-prod, sandbox, and sensitive data environments.
Finops tags and chargeback models embedded at provisioning time—not retrofitted after spend spikes.
Platform Engineering and Internal Developer Platforms
Platform teams productize golden paths: CI/CD templates, observability bundles, secrets management, and self-service infra APIs.
Internal developer platforms reduce cognitive load while enforcing architecture standards through templates rather than reviews alone.
Measure platform adoption, lead time, and developer satisfaction—not just tickets closed.
Balance golden path opinionation with escape hatches for edge cases requiring ARB approval.
Network, Identity, and Zero Trust
Network architecture evolves from perimeter-centric to identity-centric zero trust with micro-segmentation and continuous verification.
Standardize SSO, MFA, privileged access, and service identity patterns across cloud and on-prem.
Document east-west traffic flows for analytics and security monitoring.
Architecture aligns with NIST 800-207 and vendor zero trust frameworks pragmatically.
Resilience, DR, and SRE Practices
Define RTO/RPO by application tier with tested failover runbooks—not theoretical DR sites.
SRE error budgets link reliability goals to release velocity for platform services.
Chaos engineering validates assumptions on dependency failures and region loss.
Architecture standards require health checks, circuit breakers, and graceful degradation patterns in reference implementations.
Engineering Standards and Toolchains
Standardize languages, frameworks, and versions where supportability matters; allow experimentation sandboxes outside production paths.
GitOps, IaC (Terraform, Bicep, CloudFormation), and container orchestration policies documented with examples.
Supply chain security: artifact signing, dependency scanning, SBOM requirements for critical systems.
Reduce toolchain sprawl—consolidate CI/CD and observability vendors when fragmentation raises cost and skill gaps.
Lifecycle and Technical Debt in Platforms
Platform components age—OS versions, database engines, Kubernetes versions require lifecycle roadmaps.
Track platform debt separately from application debt with visible remediation funding.
Sunset announcements give product teams migration windows before unsupported states trigger audit findings.
Architecture governs exceptions with time-bound waivers and remediation owners.
Governance and ARB Integration
Technology standards changes flow through ARB with impact analysis on existing workloads.
New cloud services evaluated against security, cost, and skill criteria before enterprise approval.
Automated compliance scans report standards drift; architects focus on patterns not individual misconfigurations where automation exists.
