An enterprise Azure partner is a specialist business that designs, builds, migrates and operates Microsoft Azure platforms for large organisations, usually through a combination of consulting, operational support and licensing agreements. The right partner leaves the organisation with a secure, well-governed platform that its own teams understand, control and can change. 

At the comparison stage, most shortlists look alike on paper. Every candidate lists similar certifications, every proposal references the Cloud Adoption Framework and every sales deck promises lower running costs. The differences that matter sit in how each partner designs the platform, how it hands over control and how it behaves once the project team has moved on. This guide sets out what a capable partner should do for the business at each point, followed by questions that expose the gap between an engineering partner and a reseller with consultants attached. 

The BlakYaks team has delivered cloud solutions for enterprise and regulated organisations for more than a decade, and the criteria below reflect what separates successful engagements from those that later need rescuing. 

What does an enterprise Azure partner do? 

An enterprise Azure partner provides the engineering, operational and commercial capability an organisation needs to run its cloud platform at scale. That typically covers three services, delivered end-to-end by one firm or split across several: Azure consulting and engineering to design and build the platform, managed services to operate it, and licensing through the Cloud Solution Provider (CSP) programme. 

Separating these services before shortlisting makes proposals easier to compare, because each carries different skills, contracts and risks.

• Azure consulting and engineering 

  Azure consulting covers platform strategy, landing zone design, migration planning, application modernisation and security architecture. It is project-shaped work and its value is measured by what remains afterwards: a documented, code-driven platform and teams able to run it. 

• Managed Azure 

  Managed Azure determines whether a platform stays reliable and secure once it is live. A fault contained by rapid incident response and routine patching stays a minor incident; left unmanaged, that same fault is what reaches the business, and an unpatched vulnerability is what an auditor asks about months later. The same discipline controls cost: regular capacity planning and cost review keep spend matched to current usage, since platforms rarely stay the size they were at launch. 

  The scope ranges from full outsourcing, where the partner runs the platform end to end, to specialist engineering capacity that supplements an internal platform team during a busy period, a skills gap or a migration wave. Most enterprises land somewhere between the two, and getting that balance right matters more than the label attached to the contract.

• Licensing and billing through CSP 

  Under the CSP model, a partner resells Microsoft cloud services and bills the customer directly. With the Azure plan in CSP, the partner charges consumption at pay-as-you-go rates. Reselling capability says very little about engineering capability, which is why the two should be assessed separately. 

Match Microsoft Solutions Partner credentials to your Azure workloads 

Businesses should look for a partner whose credentials cover the specific workloads they plan to run, then test whether the people assigned to the engagement have that expertise. 

Under the Microsoft AI Cloud Partner Program, a Solutions Partner designation confirms that a firm has met the programme's thresholds for certified staff, customer growth and deployments in a solution area. Designations replaced the older Gold and Silver competency model in 2022, so a partner still leading with a Gold badge is quoting an outdated credential. Three designations cover the platform directly: Infrastructure, Data & AI, and Digital & App Innovation. Security is a fourth that matters for any enterprise cloud estate. Advanced specialisations go further, requiring audited evidence of delivery in a narrower scenario such as Kubernetes on Azure or infrastructure and database migration. 

These credentials can be verified independently through the partner listings in Microsoft Marketplace or on Microsoft's find a partner page and any claim that does not appear there should be questioned. 

Credentials set a minimum standard. They do not show which engineers will be assigned, so buyers should ask for the certifications and experience of the named team, along with case studies from organisations of similar size and regulatory profile. Success stories that describe outcomes without the architecture behind them are of limited use when comparing proven capability.

Look for an Azure partner that designs the platform before it migrates workloads 

A partner should design the foundations every application will depend on before moving the first one, so that security, networking, scalability and governance decisions are made once and applied consistently. 

Those foundations form the landing zone: the management group and subscription hierarchy, the identity model in Microsoft Entra ID, network topology, policy assignments, logging and backup. A capable partner designs them against Microsoft's Cloud Adoption Framework and Well-Architected Framework, adapts them to the organisation's regulatory obligations and operating model, and records each decision so it can be revisited as requirements change. The Enterprise Azure Landing Zone Accelerator Pack is how BlakYaks delivers this foundation. 

The same discipline applies to the migration itself. Each on-premises system should be assessed and given a destination: rehost where speed matters, re-platform or refactor where a platform service or container platform will reduce operational effort. Rehosting can be a sensible first step, but a partner that proposes lift-and-shift as the end state is moving the data centre's operational burden into the cloud without reducing it. The Migration Framework for Enterprise sets out how BlakYaks sequences this work. 

The design should also anticipate AI. Organisations moving AI from pilots into production, whether custom agents or Copilot extensions, need governed data access, private networking to model endpoints, identity-based access control and cost visibility for each use case. AI delivered as a separate project tends to create a second estate the security team cannot see. BlakYaks sets out what this means for platform teams in "Models don't transform organisations, platforms do". 

Choose an Azure partner that builds through Infrastructure as Code 

Businesses should look for a partner that delivers every part of the platform through Infrastructure as Code and automated pipelines, because that is what makes the environment repeatable, auditable and transferable to internal teams. 

When the landing zone, policies and application infrastructure are defined in code and deployed through pipelines in GitHub or Azure DevOps, every change is reviewed, tested and recorded before it reaches production. Configuration drift can be detected and corrected automatically, and environments can be rebuilt consistently for disaster recovery or a new region. The organisation also stops depending on the knowledge of individual engineers, because the intended state of the platform is written down in a form both people and pipelines can read. 

The practical questions concern ownership and access. The repositories should sit in the customer's own source control organisation from day one. Changes made by hand in the Azure portal should be the exception, handled through an agreed break-glass process and brought back into code afterwards. A partner that cannot walk through a recent deployment pipeline, including its approval gates and security checks, is unlikely to work this way in practice. The Infrastructure as Code Accelerator Pack shows the approach BlakYaks takes. 

Look for a partner that builds security and compliance into platform design 

A partner should be able to show how security and compliance controls are built into the platform it designs, so that each new application inherits them automatically instead of being reviewed one at a time. 

In practice that means least-privilege access through Entra ID and Privileged Identity Management, Azure Policy to stop non-compliant configurations from being deployed, Microsoft Defender for Cloud to assess posture continuously and Microsoft Sentinel to correlate security events. Security scanning belongs inside the delivery pipeline, so misconfigurations are caught before deployment. This is where BlakYaks concentrates its DevSecOps work with clients. 

For regulated organisations, the partner should also understand the obligations the platform must evidence, such as FCA and PRA operational resilience requirements or DORA for firms with EU operations. Cyber Essentials certification is a reasonable baseline for any firm that will hold administrative access. 

Build Azure cost management into the platform design 

Businesses should look for a partner that controls cloud costs through the platform it designs and operates, rather than relying on commercial discounts alone. 

Engineering decisions drive most cloud spend: how applications are built, how resources are sized, and when systems need to run. Switching off non-production environments outside working hours, or resizing an over-provisioned database, reduces spend without affecting the service either one supports. A capable partner makes these decisions visible and routine. 

That starts with connecting costs to the workloads and teams responsible for them. A clear subscription structure, consistent tagging enforced by policy and an agreed method for allocating shared platform costs make spend traceable in Cost Management. With that visibility, the partner can use measured demand to optimise the estate, recommending changes such as rightsizing, autoscaling or reserving capacity for predictable demand. Each recommendation should state the expected saving, any effect on performance or resilience, and who will approve and implement it. 

Commercial arrangements still matter. Organisations with a Microsoft Azure Consumption Commitment should confirm how the partner's advice on reservations, savings plans and marketplace purchases interacts with that commitment.

Keep ownership of your Azure tenant and billing 

A partner should work through delegated, auditable access to the customer's environment, leaving the business with ownership of the tenant, subscriptions, code, and billing relationship. 

The Entra tenant, and every Azure subscription within it, should belong to the organisation, with its own staff holding the highest administrative roles. Partner engineers should use time-bound, least-privilege access: granular delegated admin privileges (GDAP) when the partner also handles licensing, or Azure Lighthouse for delegated operations across subscriptions. Every access grant should be visible to the customer and removable without the partner's cooperation. 

Billing ownership needs the same scrutiny. Buying through a Microsoft CSP arrangement can simplify invoicing and bundle support, but in that model the reselling partner holds owner-level access to the subscriptions by default. The contract should state how that access is governed, and what happens to each subscription ID and tenant ID if the organisation later moves to an Enterprise Agreement, a Microsoft Customer Agreement or another reseller. 

Many partners also register Partner Admin Link against customer resources, which credits their contribution in Partner Center. It grants no access and is standard practice, but it should be disclosed. An exit plan belongs in the original contract: repositories, runbooks, architecture records and monitoring configuration handed over in usable form, with a defined transition period. 

Choose a managed Azure partner that fits your operating model 

Businesses should look for an operating model that fits the capability they intend to keep in-house, whether that is fully managed Azure, a shared operating arrangement or specialist engineering capacity on demand. 

Enterprises rarely want to outsource everything. Most retain a platform team or cloud centre of excellence and want a partner to cover out-of-hours incident response, specialist engineering and the improvement backlog the internal team cannot reach. A good managed service fits that model: changes delivered through the same code and pipelines the internal team uses, shared runbooks, and a clear division of responsibility for every alert.  

Reporting shows how well an operating partner is performing. Service reviews should cover security posture, policy compliance, recovery testing results, platform currency, cost trends and evidenced recommendations, alongside availability figures. A monthly pack limited to ticket volumes says little about whether the platform is improving. 

Questions to ask an enterprise Azure partner before signing 

These ten questions help compare shortlisted firms on the points covered above. Clear, specific answers usually indicate a partner that works this way every day. 

• Credentials: Which designations and advanced specialisations do you hold, and which named engineers will work on this engagement? 

• Evidence: Can you share examples from organisations of similar size, sector and regulatory profile, including the architecture delivered?

• Design: How will you design the landing zone, and where will you record design decisions? 

• Code: Is every change delivered through Infrastructure as Code, and who owns the repositories? 

• Security: How do security and compliance controls reach new applications, and what evidence do they produce for auditors? 

• Cost: How are costs allocated to teams, and how are optimisation recommendations presented and approved? 

• Access: What access will your engineers hold, how is it granted, and how can it be removed? 

• Billing: If you also resell our licensing, what happens to the subscriptions if billing arrangements change? 

• Operations: What does a monthly service report contain? 

• Exit: What will be handed over at the end of the engagement or on exit? 

How BlakYaks works as an enterprise Azure partner

BlakYaks is a London-based engineering and consultancy business that works exclusively with Microsoft Azure. It holds Microsoft Solutions Partner designations for Infrastructure (Azure), Digital & App Innovation (Azure), Data & AI (Azure) and Security, together with the Kubernetes on Azure specialisation, and won Cloud Technology of the Year at the UK IT Industry Awards 2025. 

BlakYaks builds and operates every platform through Infrastructure as Code. Engagements typically begin with an assessment, followed by a landing zone or enterprise Azure platform build, then migration and modernisation of the in-scope applications. Once the platform is live, SpecOps (Specialist Operations) provides daily operations cover and burst engineering capacity alongside the customer's own teams, with every change still delivered through code. 

Frequently asked questions 

• What is the difference between Azure consulting and managed Azure? 

  Azure consulting is project work that designs, builds and migrates a platform, ending with a documented environment the organisation can run. Managed services cover ongoing operation of that platform, including incident response, patching, monitoring, compliance and cost review. Many enterprises use one partner for both, provided the same engineering standards apply to each. 

• How much does Azure consulting cost in the UK? 

  Cost depends on scope, platform complexity, regulatory requirements and the seniority of the engineers involved. Assessments are often fixed price, while platform builds and migrations are priced against defined deliverables or on a time-and-materials basis. Pre-engineered accelerators reduce the effort needed for foundations such as landing zones. Proposals should tie cost to specific outputs. 

• Does buying through a CSP partner change who owns the subscriptions? 

  The customer owns its tenant and subscriptions, but in the CSP model the partner holds owner-level access to those subscriptions by default and bills for consumption. Organisations should confirm how that access is governed and how subscriptions would transfer to a different billing arrangement or provider. 

• Which credentials matter most when choosing an Azure partner? 

  The most relevant are the designations covering infrastructure, data and AI, application innovation and security, plus any advanced specialisation that matches the planned workloads, such as Kubernetes on Azure. Verify these through Microsoft's own listings and support them with the named delivery team's certifications. 

• How can an organisation assess its current platform before choosing a partner? 

  An independent assessment gives every shortlisted firm the same starting point. The BlakYaks Azure Vitals Assessment uses temporary read-only access to review security, reliability, governance and cost against Microsoft best practice and delivers a prioritised report.
