This briefing provides targeted recommendations for each leader to address critical gaps in the current Azure ecosystem vendor proposal, ensuring alignment with Microsoft Cloud Adoption Framework principles and Enterprise Security Standards.
Critical Misconception: Azure Is Not a Virtual Datacenter
The Problem
Treating Azure as a simple lift-and-shift Infrastructure-as-a-Service (IaaS) environment leads to fragmented deployments, duplicated security controls, and significant governance gaps. This outdated approach creates technical debt from day one and undermines the strategic value of cloud transformation.
Azure requires a platform-first approach that establishes standardized landing zones for identity management, policy enforcement, networking architecture, and automation frameworks before scaling workloads across the organization.
Without proper landing zone implementation, teams build workloads on unstable foundations, resulting in costly rework, audit failures, and security vulnerabilities that could have been prevented through proper architectural planning.
Key Requirement
Build standardized landing zones for identity, policy, networking, and automation before scaling workloads.
Reference: Microsoft Cloud Adoption Framework
Decentralized Controls: A Recipe for Chaos
Current State
Multiple workstreams duplicate RBAC, DevSecOps, and monitoring across products independently
The Risk
Inconsistent security posture, configuration drift, and compliance gaps across the enterprise
Required Solution
Centralize controls in platform landing zone with inheritance to all teams
Current workstreams are implementing Role-Based Access Control (RBAC), DevSecOps pipelines, and monitoring solutions independently for each product stream. This decentralized approach creates multiple versions of the same controls, each with slightly different configurations, policies, and security baselines.
The result is a fragmented security landscape where vulnerabilities in one area may not be detected or remediated in others, audit compliance becomes nearly impossible to demonstrate consistently, and operational overhead multiplies as teams maintain separate but similar infrastructure.
These controls must be centralized in a platform landing zone and inherited by all teams through Azure Policy and management group hierarchies to ensure consistency, reduce duplication, and maintain enterprise-wide compliance standards.
Ad-Hoc Security Implementation Risks
The Current Approach
Security controls including Microsoft Purview, Data Loss Prevention (DLP), and sensitivity labeling are being implemented separately for each product stream. This fragmented approach creates inconsistent coverage, gaps in protection, and makes it nearly impossible to maintain a unified security posture.
Different teams are making independent decisions about classification taxonomies, retention policies, and access controls, leading to conflicting standards and potential compliance violations.
The Required Solution
Security controls must be defined once at the tenant and management group level and enforced consistently across all workloads through Azure Policy and a unified information protection taxonomy.
This centralized approach ensures that all data, regardless of which product stream manages it, receives consistent protection based on its classification and regulatory requirements.
"Security controls must be inherited, not rebuilt per stream. Consistency is the foundation of enterprise security."
Beyond Networking: The Complete Platform Picture
While hub-and-spoke networking architecture is a necessary component of Azure enterprise deployment, it represents only one piece of a much larger platform puzzle. Focusing exclusively on networking while neglecting other critical design areas creates a false sense of readiness and leaves significant gaps in enterprise capabilities.
Networking
Hub-and-spoke topology, connectivity, and traffic management
Identity
Azure AD integration, RBAC, and privileged access management
Resource Organization
Management groups, subscriptions, and resource group hierarchy
Policy & Governance
Azure Policy, compliance frameworks, and guardrails
Management
Logging, monitoring, alerting, and operational excellence
Automation
IaC pipelines, subscription vending, and deployment automation
True enterprise readiness requires addressing identity, resource organization, policy enforcement, management capabilities, and automation together as an integrated platform. Each of these design areas must be implemented with the same rigor and attention as networking to achieve a production-ready Azure environment.
Manual Environment Setup: The Hidden Tax
The Problem
Non-reproducible infrastructure created through manual processes or ad-hoc scripts increases operational risk, slows delivery velocity, and makes audit compliance nearly impossible to demonstrate.
Each environment becomes a unique snowflake with subtle configuration differences that lead to "works in dev, fails in prod" scenarios and make troubleshooting exponentially more difficult.
Manual processes also create knowledge silos where only specific individuals understand how environments are configured, creating single points of failure in operations.
The Solution
Infrastructure-as-Code (IaC) and automated environment vending are not optional for enterprise cloud operations—they are fundamental requirements for velocity, consistency, and auditability.
Automated pipelines ensure every environment is built identically from version-controlled templates, creating reproducible infrastructure that can be audited, tested, and deployed with confidence.
This approach transforms environment provisioning from a multi-week manual process into an automated workflow that completes in hours while maintaining perfect consistency.
The Cost of Delayed Landing Zone Implementation
1
Current Approach
Building workloads before establishing platform guardrails and governance frameworks
2
Immediate Impact
Teams move quickly initially but build on unstable foundations without proper controls
3
Discovery Phase
Security gaps, compliance violations, and architectural inconsistencies are identified during audits
4
Costly Rework
Extensive remediation required to retrofit proper controls, often requiring workload rebuilds
5
Audit Failures
Regulatory compliance issues emerge, potentially resulting in fines and reputational damage
The Microsoft Cloud Adoption Framework explicitly prescribes starting with enterprise-scale landing zones and subscription vending pipelines before deploying production workloads. This "platform-first" approach may seem slower initially but prevents the exponentially higher costs of retrofitting security and governance controls after workloads are already in production. Organizations that skip this step typically spend 3-5 times more on remediation than they would have spent implementing proper landing zones from the start.
Vendor-Hosted Solutions: Hidden Risks
The Critical Issue
Delaying internal development while promoting business reliance on vendor-hosted solutions outside MNAO's Azure Enterprise Landing Zone introduces several critical risks that compound over time and can become extremely difficult to remediate.
Data Residency Concerns: Data residing in vendor-controlled environments may not comply with regulatory requirements or organizational data sovereignty policies, creating potential compliance violations.
Model Lock-In: Proprietary implementations and vendor-specific customizations make it difficult or impossible to migrate to alternative solutions, creating long-term dependency and reducing negotiating leverage.
Opaque Costs: Vendor-hosted solutions often include hidden costs for data egress, API calls, storage, and support that are not apparent in initial pricing but accumulate significantly over time.
All runtime environments and data must reside in our controlled Azure environment with continuous log export, clear support SLAs, and full audit rights to maintain security, compliance, and cost transparency.
The Vendor Sprawl Problem

Patriot Consulting
Proposed Addition
M365 Copilot Foundations and compliance/security enablement
TechMahindra
Proposed Addition
Azure AI Development and Power Platform enablement
The current and proposed approach creates significant vendor sprawl with multiple Professional Service Vendors (PSVs) engaged across overlapping workstreams. This multi-vendor model dramatically increases complexity and operational overhead while introducing several critical risks.
Each vendor brings their own processes, tools, architectural patterns, and best practices, which often conflict with each other and create integration challenges. The need for coordination across vendors slows decision-making and creates dependencies that delay delivery.
Without strong internal governance and centralized platform engineering, this fragmented approach will result in inconsistent standards, duplicated efforts, and a cloud environment that becomes increasingly difficult to manage and secure over time.
Risks of Multiple Professional Service Vendors
Fragmented Ownership
Different vendors owning separate streams leads to divergent standards, inconsistent controls, duplicated effort, and slow approval processes as coordination overhead increases exponentially.
Toolchain Drift
Competing CI/CD pipelines, monitoring tools, and security frameworks complicate integration efforts and increase maintenance overhead as teams struggle to maintain multiple parallel systems.
Velocity Drag
Cross-vendor dependencies create delays in environment setup, access provisioning, and approval workflows, significantly reducing overall delivery speed and time-to-market.
Knowledge Silos
Critical architectural decisions and operational knowledge remain with vendors rather than being transferred internally, limiting organizational capability and increasing long-term dependency.
Cost Escalation
Premium vendor rates, change orders, and ongoing support contracts often exceed the cost of building internal expertise, with costs compounding over time as dependencies deepen.
Security & Compliance Gaps
Inconsistent implementation of security baselines and compliance controls across vendors exposes the organization to audit failures, regulatory risks, and potential data breaches.
Cost Analysis: PSV vs. Internal Talent
Professional Service Vendors
Benefits
- Rapid access to specialized skills and deep technical experience
- Accelerated initial delivery for complex or unfamiliar technologies
- External perspective and best practices from multiple client engagements
Costs
- Premium hourly/daily rates (often 2–3x internal FTE cost)
- Ongoing support and change orders inflate total spend significantly
- Risk of vendor lock-in and loss of internal institutional knowledge
- Less control over prioritization and long-term strategic direction
Internal Talent
Benefits
- Lower long-term cost (salary + benefits vs. consulting rates)
- Deep organizational context and alignment with business goals
- Sustainable capability for continuous improvement and innovation
- Greater control over architecture, security, and compliance decisions
Costs
- Initial ramp-up time required for hiring and training processes
- Investment needed in upskilling programs or professional certifications
- Potential gaps in niche expertise during early implementation phases
3-Year Cost Comparison
$3M-$4.8M
PSV Total Cost
$250–$400/hr × 2 FTEs × 2,000 hrs/year × 3 years (plus change orders and ongoing support fees)
$900K-$1.2M
Internal Talent Cost
$150K–$200K/year × 2 FTEs × 3 years (including training and certification investments)
70%
Potential Savings
Building internal capability can reduce costs by up to 70% over a three-year horizon while increasing organizational knowledge
Strategic Recommendation: Use PSVs for targeted, time-bound accelerators such as initial landing zone setup and architecture reviews, but prioritize onboarding and developing internal talent for ongoing platform engineering, governance, and cloud operations. This hybrid approach maximizes velocity and sustainability while minimizing long-term cost and dependency risk.
The cost differential becomes even more pronounced when considering that vendor rates typically increase annually, while internal talent costs remain more predictable. Additionally, internal teams build institutional knowledge that compounds in value over time, whereas vendor knowledge often leaves with the consultants when engagements end.
Recommendations for Maggie Hubble: Data & AI Products
01
Centralize Platform Controls
Ensure all Data & AI products inherit RBAC, policy enforcement, and monitoring capabilities from a single platform landing zone. Eliminate the practice of duplicating controls in each product stream, which creates inconsistency and increases operational overhead.
02
Standardize Environment Vending
Implement Infrastructure-as-Code (IaC) and automated pipelines for Dev/Test/Prod environment provisioning. Promote reusable blueprints specifically designed for Copilot, Power Platform, and AI workloads to accelerate delivery while maintaining consistency.
03
Unified Data Governance
Deploy Microsoft Purview, Data Loss Prevention (DLP), and sensitivity labeling at the tenant level rather than implementing separate instances per product. Extend comprehensive coverage to all Data & AI services through centralized policy inheritance.
These recommendations align Data & AI initiatives with enterprise platform standards, reducing duplication while accelerating time-to-market for new capabilities. By inheriting platform controls rather than rebuilding them, product teams can focus on delivering business value rather than managing infrastructure and security controls.
Recommendations for Ray Griffin: Chief Information Security Officer
Enforce Security Baselines
All workloads must comply with Azure Policy, Microsoft Defender for Cloud, and centralized logging through Azure Sentinel. Security controls must be inherited from platform landing zones, not rebuilt per stream.
Data Residency & Privacy
Require all data, logs, and encryption keys to remain within our Azure Enterprise Landing Zone. Prohibit vendor-hosted solutions unless they provide continuous log export and full audit rights.
Incident Response & Compliance
Standardize incident response runbooks and compliance reporting across all Data & AI workloads to ensure consistent security operations and regulatory adherence.
These security-focused recommendations establish a Zero Trust architecture with defense-in-depth principles applied consistently across the entire Azure environment. By centralizing security controls and requiring inheritance rather than duplication, the organization can maintain a stronger security posture with less operational overhead.
The emphasis on data residency and continuous audit capabilities ensures that even when working with external vendors, MNAO maintains full visibility and control over all security-relevant events and data access patterns.
Recommendations for Neeru Arora: Executive CIO
1
Establish Internal Governance of Cloud Architecture
Integrate Cloud Governance responsibilities into the Enterprise & Experience Architecture Review Board (EEARB) to oversee landing zone adoption, policy enforcement, and alignment with Cloud Adoption Framework (CAF) and Well-Architected Framework (WAF) principles across all initiatives.
2
Accelerate Platform Enablement
Direct internal teams to implement enterprise-scale landing zones using Microsoft accelerators and reference architectures. Ensure Zero Trust principles and Security by Design are embedded from the foundation rather than retrofitted later.
3
Organizational Alignment
Define clear RASCI (Responsible, Accountable, Supportive, Consulted, Informed) matrices for platform engineering, product teams, and security functions. Ensure all streams follow standardized IaC and DevSecOps practices to maintain consistency and quality.
4
Continuous Improvement
Mandate periodic reviews of architecture and compliance posture against Well-Architected Framework pillars and Cloud Adoption Framework design areas. Establish metrics and KPIs to track platform maturity and adoption progress.
These executive-level recommendations establish the governance structure and organizational alignment necessary for successful cloud transformation at enterprise scale. By integrating cloud governance into existing architectural review processes and clearly defining roles and responsibilities, MNAO can ensure consistent execution while maintaining agility and innovation velocity.
Revised Workstream Proposal: Three-Layer Architecture
Platform Layer
Establish enterprise-scale landing zones centralizing identity, RBAC, policy, networking, monitoring, and incident response. Implement subscription vending, Azure Policy, Defender for Cloud, and centralized CI/CD pipelines with reusable IaC modules.
Product Layer
Create product-specific landing zones for M365 Copilot, Power Platform/Fabric, and AI services that consume platform guardrails. Standardize environment strategies (Dev/Test/QA/Prod) and integrate with platform pipelines.
Application Landing Zones
Onboard application workloads via automated subscription vending with consistent governance, security, and monitoring inherited from Platform layer. Enable rapid deployment and scaling without duplicating foundational work.
This three-layer architecture eliminates duplication of RBAC, DevSecOps, and monitoring across streams by centralizing these capabilities in the Platform layer. It provides consistent policy enforcement and compliance controls across all workloads while implementing Zero Trust principles and Security by Design through centralized identity, policy, and monitoring.
The structure follows Microsoft Cloud Adoption Framework and Well-Architected Framework guidance for enterprise-scale landing zones, ensuring alignment with industry best practices and Microsoft's recommended patterns.
Benefits of the Three-Layer Approach
Efficiency
Eliminates duplication by centralizing controls in Platform layer
Governance
Provides consistent policy enforcement across all workloads
Security
Implements Zero Trust and Security by Design principles
Alignment
Follows CAF and WAF guidance for enterprise-scale
Velocity
Accelerates delivery through reusable patterns and automation
Cost Control
Reduces operational overhead and vendor dependencies
This structure reduces complexity, accelerates delivery, and ensures all streams adhere to enterprise standards while enabling innovation at the product and application levels. By minimizing vendor sprawl and partnering with a single professional services vendor (PSV) to support Platform, Product, and Application Landing Zone (ALZ) initiatives, MNAO can further streamline processes, increase velocity, and reduce time to value across all areas of focus.
The centralized platform approach also creates a foundation for continuous improvement, allowing the organization to evolve security controls, compliance frameworks, and operational practices once and have those improvements automatically inherited by all downstream workloads.
