7 Actionable Resources for Finding Top Cloud Migration Consulting Companies
Choosing the right partner is the most critical decision in a cloud migration. A misstep leads to budget overruns, security vulnerabilities, and stalled projects. The market is saturated with firms making similar promises. This guide cuts through the noise. We don’t list individual firms, as the “best” is subjective to your business context.
Instead, this guide provides a curated list of definitive, high-trust directories and marketplaces where you can find, vet, and compare top-tier cloud migration consulting companies. These are the official, data-driven sources used by experienced CTOs to build shortlists for everything from a simple lift-and-shift to a complex enterprise transformation on AWS, Azure, or Google Cloud. Forget generic web searches that yield sponsored results; this is your playbook for finding a partner that aligns with your technical requirements, compliance needs, and budget.
This article details the seven most effective platforms for building your vendor shortlist. For each source, we provide:
- A direct link and screenshots for navigation.
- A clear breakdown of how to filter for certified migration specialists.
- Actionable advice on vetting partners within that ecosystem.
This data-driven approach helps you stop searching and start vetting. By focusing on these verified platforms, you can identify and engage with consultants who have proven expertise on your chosen cloud platform, ensuring your migration is efficient and secure.
1. AWS Marketplace (Professional Services – Cloud Migration)
For organizations in the Amazon Web Services ecosystem, the AWS Marketplace offers a direct path to engaging with cloud migration consulting companies. It functions as a digital catalog where you can procure pre-defined professional services from vetted AWS Partners. This model accelerates the procurement cycle by leveraging standardized AWS Marketplace agreements, bypassing lengthy contract negotiations.
The platform is effective for sourcing specific, fixed-scope projects like a migration readiness assessment, a pilot application migration, or a database replatforming project. This approach allows you to test a consulting partner on a smaller scale before committing to a larger transformation.
Why It Stands Out
AWS Marketplace integrates the procurement and billing of consulting services into your existing AWS account. This centralization simplifies vendor management and provides consolidated spending visibility. You can compare offers with clearly defined deliverables, timelines, and sometimes fixed pricing, making it easier to evaluate options directly.
Key Insight: The primary advantage is speed and simplicity. Using the Marketplace, you can transact with a global pool of partners under a single, familiar legal and billing framework, reducing procurement friction from months to weeks.
Platform Scorecard
| Feature | Score (1-5) | Notes |
|---|---|---|
| Procurement Speed | ⭐⭐⭐⭐⭐ | Leverages existing AWS agreements for rapid engagement. |
| Partner Variety | ⭐⭐⭐⭐ | Extensive selection, but primarily AWS-centric specialists. |
| Pricing Transparency | ⭐⭐⭐ | Many listings require a “Request a Quote” step for final pricing. |
| Customization | ⭐⭐⭐⭐ | Offers private offer workflows for tailoring scopes beyond listed services. |
| Project Suitability | ⭐⭐⭐⭐ | Best for assessments, pilots, and well-defined migration phases. |
How to Use It Effectively
- Filter by Competency: Use filters to find partners holding specific AWS Migration or DevOps Competencies. This ensures you’re working with firms that have a track record validated by AWS.
- Start Small: Purchase a “Migration Readiness Assessment” or a “Well-Architected Review” as a low-risk first engagement. This lets you evaluate a partner’s expertise and cultural fit.
- Use Private Offers: For projects that don’t fit a standard listing, use the “Request a Private Offer” feature to negotiate a custom scope and price directly with the partner, while still using the Marketplace’s streamlined contracting and billing.

2. AWS Migration and Modernization Competency Partners (Official Directory)
For enterprises undertaking complex migrations to AWS, the official Competency Partner directory is a high-trust starting point. This is not a transactional platform but a curated list of cloud migration consulting companies that have undergone a rigorous validation process by AWS. Inclusion requires demonstrating deep technical proficiency and proven customer success through case studies and references, making it an essential resource for de-risking major projects.
This directory is the go-to source when your primary goal is to identify partners with the highest level of validated expertise, particularly in regulated industries. The focus here is less on procurement speed and more on the assurance of quality and experience.
Why It Stands Out
The key differentiator is the AWS Competency validation. This is a certification that a partner has passed AWS’s highest technical bar for a specific solution area. This vetting provides a level of confidence that is hard to replicate through independent research, significantly narrowing the field to only the most capable firms.
Key Insight: This directory is your best tool for creating a high-quality shortlist. It filters out less experienced providers, allowing you to focus your evaluation on partners already confirmed by AWS to have the skills to handle enterprise-grade complexity.
Platform Scorecard
| Feature | Score (1-5) | Notes |
|---|---|---|
| Partner Vetting | ⭐⭐⭐⭐⭐ | The highest level of AWS validation, requiring proven success. |
| Project Suitability | ⭐⭐⭐⭐⭐ | Ideal for complex, multi-phased, and enterprise-wide migrations. |
| Procurement Speed | ⭐⭐ | Functions as a directory; requires traditional, offline RFP and scoping. |
| Pricing Transparency | ⭐ | No pricing information is provided; all engagements are custom-quoted. |
| Partner Variety | ⭐⭐⭐⭐ | Extensive list of top-tier partners, but all are AWS-focused. |
How to Use It Effectively
- Distinguish Between Competencies: Understand the difference between the “Migration” and “Modernization” competencies. Use the Migration filter for lift-and-shift or re-platforming projects and the Modernization filter for partners specializing in application refactoring.
- Use It for RFI/RFP Shortlisting: Treat the directory as the first step in your procurement process. Identify 3-5 partners with relevant case studies and invite them into a formal Request for Proposal (RFP) process.
- Cross-Reference with Industry Expertise: After shortlisting partners, investigate their specific experience within your industry (e.g., financial services, healthcare). The Competency proves technical skill, but domain knowledge is equally critical.

3. Microsoft Azure Marketplace – Consulting Services (Migration)
For businesses committed to the Microsoft ecosystem, the Azure Marketplace provides a portal to find and engage with cloud migration consulting companies. It operates as a curated catalog of professional services, allowing organizations to procure fixed-scope migration offerings directly from Microsoft-certified partners. This model is designed to simplify and accelerate sourcing migration expertise.
The platform excels at connecting users with time-boxed, outcome-based engagements. You can find offers for a multi-week migration implementation, an SAP on Azure assessment, or a proof-of-concept for a specific workload. This allows teams to engage partners for discrete migration phases with clear deliverables and timelines from the outset.
Why It Stands Out
The Azure Marketplace streamlines the procurement of consulting services by integrating them with your existing Azure subscription and enterprise agreements. This tight integration means you can discover a partner, agree to a scope, and manage the engagement through a familiar procurement channel. The listings often provide transparent scopes and clearly defined deliverables, which makes comparing different cloud migration consulting companies more straightforward.
Key Insight: The core benefit is structured engagement. By focusing on packaged, outcome-based offers, the Marketplace helps you avoid scope creep and ensures alignment on goals before a project begins, which is critical for budget-conscious, phased migrations.
Platform Scorecard
| Feature | Score (1-5) | Notes |
|---|---|---|
| Procurement Speed | ⭐⭐⭐⭐ | Integrates with existing Azure agreements for faster onboarding. |
| Partner Variety | ⭐⭐⭐⭐ | Strong global and regional partner network, but focused on Azure specialists. |
| Pricing Transparency | ⭐⭐⭐ | Many offers are listed with a “Contact Me” button instead of fixed pricing. |
| Customization | ⭐⭐⭐ | Less flexible than open-ended SOWs; best for standardized project types. |
| Project Suitability | ⭐⭐⭐⭐ | Excellent for assessments, proofs-of-concept, and workload-specific migrations. |
How to Use It Effectively
- Filter by Solution Area: Use the “Migration” and “Modernize” category filters to narrow the list of partners to those with specific, relevant offers.
- Evaluate Packaged Offers: Look for offers like “Azure Migration Assessment” or “Windows Server Migration” to start a relationship. These fixed-scope engagements are ideal for evaluating a partner’s technical skill.
- Leverage Partner Certifications: Prioritize partners holding “Azure Expert MSP” or advanced specializations like “Windows Server and SQL Server Migration to Microsoft Azure.” These credentials are a strong indicator of validated expertise.
To help frame your partner selection process, it’s useful to compare cloud service providers and understand the unique strengths of the Azure platform.
Website: https://azuremarketplace.microsoft.com/en-us/marketplace/consulting-services/category/migration
4. Microsoft “Find a Microsoft partner” (Solution Provider Directory)
For enterprises committed to Microsoft Azure, the official “Find a Microsoft partner” directory is the authoritative starting point for sourcing qualified cloud migration consulting companies. This platform is not a marketplace but a directory of solution providers that have earned specific Microsoft designations and specializations. It is designed to connect businesses with vetted experts for complex Azure migration projects that demand deep technical expertise.
The directory excels at helping organizations identify partners with proven capabilities, particularly those holding the elite “Azure Expert Managed Service Provider (MSP)” status. This designation signifies that a partner has passed a rigorous third-party audit of their technical skills and ability to manage complex Azure environments.
Why It Stands Out
The Microsoft partner directory’s core strength is its trust and validation model. The platform clearly displays partner tiers, such as Solutions Partner designations and advanced specializations in areas like “Migrate Enterprise Applications to Microsoft Azure.” This allows you to quickly shortlist firms based on Microsoft’s own stamp of approval, which is critical for projects involving sensitive data or mission-critical workloads.
Key Insight: This directory is your best resource for due diligence. It prioritizes verified expertise over transactional speed, making it ideal for initiating strategic, long-term partnerships rather than purchasing fixed-scope services.
Platform Scorecard
| Feature | Score (1-5) | Notes |
|---|---|---|
| Partner Vetting | ⭐⭐⭐⭐⭐ | Rigorous validation through Solutions Partner designations and specializations. |
| Procurement Speed | ⭐⭐ | Functions as a directory; requires traditional outreach and contract negotiation. |
| Pricing Transparency | ⭐ | No pricing information is available. Requires direct contact for proposals. |
| Customization | ⭐⭐⭐⭐⭐ | Engagements are fully bespoke and tailored to specific business needs. |
| Project Suitability | ⭐⭐⭐⭐ | Best for large, complex, or regulated migrations requiring deep, custom expertise. |
How to Use It Effectively
- Filter by Specialization: Go beyond the basic filters. Look for advanced specializations like “Windows Server and SQL Server Migration” or “Linux and Open Source Databases Migration to Azure” to find partners with skills relevant to your tech stack.
- Prioritize Azure Expert MSPs: If you are planning a large migration that will require ongoing management, start your search by filtering for Azure Expert MSPs. This is Microsoft’s highest level of partner endorsement.
- Use the Directory for RFP Shortlisting: Treat the platform as a tool for building your Request for Proposal (RFP) distribution list. Identify 3-5 partners with relevant industry experience and specializations, then initiate your formal evaluation process.
Website: https://partner.microsoft.com/en-us/partnership/find-a-partner
5. Google Cloud Marketplace – Partner-delivered Professional Services (US)
For businesses committed to Google Cloud, the Google Cloud Marketplace offers a streamlined avenue for procuring professional services from vetted partners. This platform acts as a digital catalog, allowing US-based customers to purchase services like migration assessments and implementations directly. This model leverages existing Google Cloud billing and contractual frameworks, which can reduce the time and complexity of vendor onboarding.
The platform is most effective for acquiring well-defined, project-based services. For example, you might purchase an implementation service package from a partner at the same time you procure their data analytics software. This integrated approach ensures that the expertise you need is directly aligned with the technology you are deploying.
Why It Stands Out
Google Cloud Marketplace’s key differentiator is its ability to bundle software and related professional services into a single transaction. This simplifies procurement by consolidating purchases onto your Google Cloud invoice, offering clear visibility into total solution costs. The ability to use committed use discounts (CUDs) towards eligible Marketplace purchases further enhances its financial appeal.
Key Insight: The main advantage is the unified procurement experience. By transacting through the Marketplace, you can retire your Google Cloud spending commitments while simultaneously engaging expert cloud migration consulting companies, all under one billing and contractual umbrella.
Platform Scorecard
| Feature | Score (1-5) | Notes |
|---|---|---|
| Procurement Speed | ⭐⭐⭐⭐ | Fast for existing Google Cloud customers with established billing. |
| Partner Variety | ⭐⭐⭐ | Growing selection, but more limited than software listings and other marketplaces. |
| Pricing Transparency | ⭐⭐⭐⭐ | Many services have listed prices for specific scopes; custom pricing available via private offers. |
| Customization | ⭐⭐⭐⭐ | Private offers allow for negotiating tailored scopes and pricing for complex projects. |
| Project Suitability | ⭐⭐⭐ | Ideal for assessments, software implementation, and managed services tied to a product. |
How to Use It Effectively
- Search by Partner and Expertise: Use the search filters to identify partners with specific Google Cloud Specializations, such as Cloud Migration or Infrastructure. This ensures you are engaging with firms recognized by Google.
- Leverage Private Offers: For any migration project that extends beyond a pre-packaged service, request a Private Offer. This allows a partner to create a custom engagement with a unique scope, timeline, and price.
- Bundle Services with Software: When planning to use a third-party tool for your migration, check if the software vendor or a certified partner offers implementation services directly on the Marketplace. This simplifies the purchase and deployment process.

6. Google Cloud Partner Advantage – Find Partners
For businesses on Google Cloud Platform (GCP), the Partner Advantage directory is the authoritative source for identifying and vetting qualified cloud migration consulting companies. This platform is a curated discovery tool, enabling IT leaders to find partners with proven, Google-validated expertise in areas like Cloud Migration and Infrastructure Modernization. The directory is designed for initiating strategic partnerships rather than quick service purchases.
The focus is on verification and specialization. Partners are distinguished by tiers (Partner, Premier) and specific Specialization or Expertise badges, earned by demonstrating technical proficiency and customer success. This ensures that when you engage a partner, they have a documented history of success validated by Google.
Why It Stands Out
The Google Cloud Partner Advantage directory excels at providing trust and assurance. The rigorous requirements for earning a “Cloud Migration Specialization” mean you are shortlisting firms that have passed technical assessments and submitted multiple customer case studies for review. This high validation bar de-risks the partner selection process for complex migrations.
Key Insight: The primary advantage is confidence in expertise. The directory isn’t built for speed but for certainty, connecting you with partners whose migration capabilities have been scrutinized by Google Cloud, making it ideal for high-stakes projects.
Platform Scorecard
| Feature | Score (1-5) | Notes |
|---|---|---|
| Partner Vetting | ⭐⭐⭐⭐⭐ | Rigorous specialization and tiering system provides high assurance. |
| Partner Variety | ⭐⭐⭐⭐ | Strong global and industry coverage, exclusively for GCP ecosystem partners. |
| Pricing Transparency | ⭐⭐ | Functions as a directory; pricing requires direct engagement and proposals. |
| Procurement Speed | ⭐⭐ | Traditional RFP and SOW process; no streamlined purchasing flow. |
| Project Suitability | ⭐⭐⭐⭐ | Best for complex, strategic migrations requiring custom-scoped projects. |
How to Use It Effectively
- Filter by “Cloud Migration Specialization”: Start your search by applying this filter. This is the highest level of technical validation for migration services and immediately narrows your list to the most proven partners.
- Review Customer Stories: Pay close attention to the case studies on a partner’s profile. Look for examples that mirror your industry, scale, or the specific technologies you need to migrate.
- Engage Multiple Premier Partners: For a major migration, identify two to three “Premier” partners with the relevant specialization. Engaging multiple firms for initial discovery calls allows you to compare their methodologies and cultural fit.

7. Clutch – Cloud Migration Services Category
For businesses seeking a broad, vendor-agnostic market overview, Clutch serves as a B2B marketplace driven by verified client reviews. Its Cloud Migration Services category allows you to compare a diverse range of cloud migration consulting companies based on real-world client feedback. Unlike vendor-specific marketplaces, Clutch provides a neutral ground where you can evaluate firms specializing in AWS, Azure, GCP, and multi-cloud environments side-by-side.
The platform is useful during the initial research and shortlisting phase. It allows you to gather multiple quotes and understand market rates by filtering providers based on hourly rates, minimum project size, industry focus, and location. This data-rich approach helps build a preliminary list of potential partners before deeper technical evaluations.
Why It Stands Out
Clutch’s primary value lies in its transparent, review-driven methodology. Each company profile features detailed, interview-based client reviews that cover project management, communication, quality of service, and results. This qualitative data provides insights into a firm’s operational style that you can’t get from a list of certifications. The platform’s “Leaders Matrix” also offers a visual snapshot of top-performing firms.
Key Insight: Clutch excels at demystifying the crowded consulting market. By focusing on verified client experiences, it helps you move beyond marketing claims and evaluate potential partners based on proven performance and peer feedback.
Platform Scorecard
| Feature | Score (1-5) | Notes |
|---|---|---|
| Partner Variety | ⭐⭐⭐⭐⭐ | Excellent selection across AWS, Azure, GCP, and boutique providers. |
| Review Credibility | ⭐⭐⭐⭐ | Verified reviews are a strong point, but sponsored placements can influence rankings. |
| Pricing Transparency | ⭐⭐⭐⭐ | Many firms list hourly rates and minimum project sizes, aiding budget alignment. |
| Vetting Depth | ⭐⭐ | Lacks formal validation of cloud vendor certifications; verification is your responsibility. |
| Project Suitability | ⭐⭐⭐⭐ | Ideal for market research, shortlisting, and finding partners for SMB or mid-market projects. |
How to Use It Effectively
- Filter Aggressively: Use the filters for location, industry focus, and client budget to narrow the list. Pay close attention to the “Minimum Project Size” to avoid contacting firms outside your budget range.
- Read the Full Reviews: Don’t just look at the star rating. Dive into the full text of client interviews to understand the project context, challenges faced, and how the consultant performed.
- Cross-Verify Certifications: Clutch does not independently verify AWS Competencies or Azure Expert MSP status. Once you’ve shortlisted a firm, visit the respective cloud provider’s partner portal to confirm their credentials.

Your Next Steps: From Shortlist to Signed Contract
Navigating the landscape of cloud migration consulting companies is manageable with a structured approach. The directories above provide a powerful starting point. Official partner ecosystems from AWS, Microsoft, and Google Cloud offer vetted, platform-specific expertise. Third-party aggregators like Clutch provide a broader market view with client reviews.
The “best” partner is never a one-size-fits-all answer. Your ideal partner exists at the intersection of your specific technical needs, budget, and business goals.
Synthesizing Your Research into a Shortlist
Now, the work of due diligence begins. Your goal is to distill potential firms into a focused shortlist of three to five qualified candidates. Use the following framework to build your shortlist:
- Platform & Tooling Alignment: Does the firm have deep, certified expertise in your target cloud (AWS, Azure, GCP)? Do they have proven experience with relevant migration tools like AWS Migration Hub, Azure Migrate, or Google Cloud Migrate for Compute Engine?
- Industry & Compliance Validation: For businesses in finance, healthcare, or government, this is non-negotiable. Look for partners who list HIPAA, PCI-DSS, FedRAMP, or GDPR compliance as a core competency. Ask for case studies from clients in your specific vertical.
- Project Complexity Match: Review their past projects. Are they handling straightforward rehosting projects, or do they have a portfolio of complex refactoring and re-architecting initiatives? Ensure their experience matches your migration roadmap.
From Shortlist to RFP: Asking the Right Questions
With your shortlist in hand, craft a detailed Request for Proposal (RFP). A well-structured RFP moves beyond generic questions and forces potential cloud migration consulting companies to demonstrate their strategic thinking. Your RFP should compel candidates to address these key areas:
- Proposed Migration Strategy: Insist on a preliminary outline of their recommended approach. Will they use a phased “move group” strategy? What discovery tools will they deploy? This reveals their methodological rigor.
- Team Composition and Certifications: Request profiles of the key personnel who would be assigned to your project. Verify their certifications (e.g., AWS Certified Solutions Architect - Professional, Azure Solutions Architect Expert) and years of experience.
- Governance and Security Framework: How will they ensure security and compliance during the migration? Ask for their approach to identity and access management (IAM), data encryption, and post-migration security posture validation.
- Post-Migration Support and Optimization: A successful project doesn’t end when the last server is moved. Ask about their models for ongoing managed services, cost optimization (FinOps), and performance tuning. This separates a transactional vendor from a strategic partner.
By structuring your evaluation this way, you gain the data needed to make an informed decision. You are not just buying a service; you are investing in a partnership that will shape your organization’s technology foundation for years.
