1. CloudConsultingFirms.com
Instead of starting with a single vendor, our top recommendation is an independent research platform designed to streamline vendor selection. CloudConsultingFirms.com acts as a data-driven buying guide, empowering technical leaders to find and vet the best cloud migration companies across AWS, Azure, and Google Cloud. It shifts the focus from marketing claims to verifiable evidence, making it an indispensable first step for any cloud initiative.
The platform’s strength is its independent methodology. Its rankings and shortlists are built on aggregated data, analyzing thousands of verified client reviews, partner certifications, and documented project outcomes. This quantitative approach is combined with qualitative insights on pricing benchmarks, team size, and compliance capabilities, offering a holistic view of the market.
Why It Stands Out: Actionable Intelligence, Not Just a Directory
CloudConsultingFirms.com excels by providing practical tools that translate complex data into clear, actionable decisions. Its interactive quiz generates a tailored shortlist of potential partners based on your timeline, budget, and technical priorities.
The platform provides a high level of transparency regarding costs and capabilities. It profiles leading firms and analyzes over 100 partners, assigning clear scores (e.g., Slalom 9.2/10, Caylent 9.0/10) and detailing typical project costs. This allows teams to benchmark potential partners effectively, whether they are a mid-market company with a sub-$200K budget or an enterprise planning a multi-million-dollar transformation. For a deeper look at how it evaluates vendors, explore the guide to top cloud migration consultants on CloudConsultingFirms.com.
Key Features and How to Use Them
To maximize the value of the platform, focus on these core features:
- Interactive Partner Matching Quiz: Use this tool as your starting point to get an initial, unbiased shortlist based on your project’s core parameters (cloud platform, budget tier, primary goal).
- Platform & Capability Filters: After generating a shortlist, use the filters to narrow down partners by specific competencies like FinOps, complex data architecture, healthcare compliance (HIPAA), or 24/7 managed services.
- Vendor Profile Analysis: Dive into individual profiles to review partner tiers (e.g., AWS Premier, Azure Expert MSP), verified certifications, and recurring themes from client reviews. Look for evidence of success in your specific industry.
- Pricing & ROI Calculators: Leverage the provided pricing benchmarks (e.g., Mission Cloud $100K+, Accenture $250K–$1M+) to sanity-check proposals and build a preliminary business case before issuing an RFP.
The site is explicitly independent and labels any featured or paid placements, ensuring you can distinguish between organic recommendations and sponsored content. This commitment to transparency, combined with regular research updates, helps reduce procurement risk and equips your team with the data needed for informed due diligence.

2. AWS Partner Solutions Finder – Migration and Modernization Partners
For organizations committed to the Amazon Web Services ecosystem, the official AWS Partner Solutions Finder is the direct and reliable starting point for identifying qualified cloud migration partners. This platform is a curated directory of AWS-vetted consulting and software partners, each holding a validated Migration and Modernization Competency. This means every listed partner has a proven track record and deep technical proficiency for complex migration projects on AWS.
This directory de-risks your partner selection process. It eliminates guesswork by presenting only those firms that have met Amazon’s stringent requirements. This pre-qualification saves your team valuable due diligence time and ensures you engage with some of the best cloud migration companies that specialize in the AWS platform.
Key Features and User Experience
The platform’s strength lies in its powerful and specific filtering capabilities, allowing you to quickly narrow down the extensive list of partners to find the ideal fit.
- Migration vs. Modernization Focus: Filter specifically for partners who excel at “lift-and-shift” migrations or those who specialize in application modernization (e.g., re-platforming, re-architecting).
- Workload Specialization: Find experts for migrating specific workloads such as Windows Server, SAP, databases, or mainframe systems.
- Industry and Geographic Filters: Zero in on partners with experience in your specific industry (e.g., Financial Services, Healthcare) and who operate in your geographic region.
- Access to Partner Resources: Each partner profile provides direct access to collateral like case studies, whitepapers, and webinars.
Pricing and Engagement Model
The AWS Partner Solutions Finder does not list pricing. It functions as a directory to connect you with partners. You must contact potential partners directly to request proposals.
A significant advantage of using this directory is the alignment with AWS-funded programs. Many listed partners can help you access initiatives like the AWS Migration Acceleration Program (MAP), which can provide credits to offset the costs of the assessment, planning, and migration phases.
Expert Tip: When contacting a partner through the Finder, explicitly ask about their experience with the AWS MAP program. Their ability to help you secure funding can significantly reduce your upfront migration investment and is a key indicator of a mature AWS partnership.
| Feature Summary | AWS Partner Solutions Finder |
|---|---|
| Partner Focus | Exclusively AWS Competency Partners |
| Cost Model | Free to use; must request quotes from partners |
| Key Advantage | Vetted partners; alignment with AWS funding programs |
| Best For | Organizations committed to migrating to AWS |

3. AWS Marketplace – Professional Services (Cloud Migration)
For organizations seeking a transactional and productized approach to migration services, the AWS Marketplace offers a direct procurement channel. This is a platform where you can discover, purchase, and deploy pre-packaged professional services from many of the best cloud migration companies. This model is ideal for teams that need to engage a partner for a well-defined, fixed-scope project like a readiness assessment or a specific workload migration.
The key differentiator of the Marketplace is streamlined procurement. By offering standardized service listings with clear deliverables, it can transform a lengthy RFP process into a straightforward transaction. You can procure migration services directly through your AWS account, simplifying vendor onboarding, contracting, and billing into a single invoice.
Key Features and User Experience
The platform is designed for procurement efficiency, allowing users to find and contract for specific migration engagements with minimal friction.
- Catalog of Fixed-Scope Services: Browse a wide range of pre-defined migration services, from initial TCO assessments and mobilization planning to the migration of specific applications like SAP or Windows Server.
- Standardized Deliverables: Each listing clearly outlines the scope, activities, and deliverables, such as a target architecture diagram, a TCO model, or a detailed migration runbook.
- In-Platform Engagement: Users can ask questions, request custom proposals, and negotiate private offers directly with vendors within the Marketplace interface.
- Simplified Procurement: Contracting and billing are handled through your existing AWS account, which can accelerate the procurement cycle.
Pricing and Engagement Model
Pricing is transparently listed for many standardized offerings, though custom projects will require a private offer from the vendor. This model is beneficial for organizations looking to use their committed AWS spend, as Marketplace transactions can often count towards an Enterprise Discount Program (EDP) commitment.
Many partners use the Marketplace to offer low-cost or no-cost assessments, often subsidized by AWS programs and subject to eligibility criteria. This provides a low-risk entry point to evaluate a partner’s capabilities. It’s crucial to confirm eligibility and the scope of these offers directly with the listing partner.
Expert Tip: Use the AWS Marketplace to run a pilot or initial assessment. The standardized contracting and rapid procurement make it an excellent tool for testing a new migration partner on a small, defined project before committing to a larger engagement.
| Feature Summary | AWS Marketplace – Professional Services |
|---|---|
| Partner Focus | Broad range of AWS Partners offering packaged services |
| Cost Model | Public and private pricing; transact via AWS account |
| Key Advantage | Streamlined procurement and standardized service scopes |
| Best For | Teams needing to quickly procure defined-scope assessments or pilots |

4. Microsoft Azure – Find an Azure Partner + Azure Marketplace Consulting Offers
For organizations standardizing on Microsoft Azure, the official partner ecosystem is the definitive source for finding validated cloud migration partners. This platform is a dual resource, combining the Find an Azure Partner directory with transactable Azure Marketplace Consulting Offers. This allows businesses to discover top-tier Azure Solutions Partners and directly procure standardized migration services.
The primary benefit is the rigorous vetting and specialization framework Microsoft has in place. Partners listed here often hold advanced specializations or the Azure Expert MSP designation. This system provides a clear, credible signal of a partner’s technical expertise and proven success in executing complex migration projects, making it an essential tool for any company looking for the best cloud migration companies specializing in Azure.
Key Features and User Experience
The platform helps you pinpoint the right expertise by leveraging Microsoft’s certification and specialization programs. It merges a partner directory with a services marketplace.
- Verified Capability Tiers: You can filter for elite partners, such as Azure Expert MSPs, who have passed a demanding third-party audit of their technical skills and managed services capabilities.
- Advanced Specializations: The directory lets you identify partners with specific, verified expertise in migrating key workloads like Windows Server and SQL Server, Linux and Open Source Databases, and SAP on Azure.
- Transactable Consulting Offers: The Azure Marketplace features fixed-scope, often fixed-price consulting offers for services like migration assessments, readiness planning, and pilot migrations.
- Geographic and Industry Search: Users can easily filter the partner directory by location, industry focus (e.g., Healthcare, Financial Services), and company size.
Pricing and Engagement Model
Pricing information varies. The “Find a Partner” directory does not list pricing; you must contact partners for quotes. In contrast, the Azure Marketplace often lists pricing for standardized consulting offers, providing budget transparency for initial assessment phases.
Many partners found through this ecosystem can help customers leverage Microsoft funding programs like the Azure Migration and Modernization Program (AMMP). This program can provide guidance and funding to offset migration costs.
Expert Tip: When browsing the Azure Marketplace, look for “Assessment” or “Proof-of-Concept” consulting offers. These can be a low-risk, cost-effective way to evaluate a potential partner’s capabilities and build a business case before committing to a full-scale migration project.
| Feature Summary | Microsoft Azure Partner Ecosystem |
|---|---|
| Partner Focus | Exclusively Azure Solutions Partners & Expert MSPs |

5. Google Cloud Partner Directory (Partner Advantage)
For businesses prioritizing Google Cloud Platform (GCP), the official Google Cloud Partner Directory is the authoritative source for finding qualified migration experts. This platform, part of the Partner Advantage program, is a curated list of partners who have demonstrated expertise on GCP. Partners with a “Cloud Migration” specialization have been vetted by Google, ensuring they possess the technical skills and methodologies required for successful cloud transitions.
Using this directory streamlines the vetting process for companies seeking the best cloud migration companies within the GCP ecosystem. It provides assurance by presenting partners who have met Google’s standards for technical proficiency. This pre-qualification allows IT leaders to focus their evaluation efforts on a shortlist of capable firms.
Key Features and User Experience

- Geographic Search: Easily find partners who operate in your specific region, which is crucial for support and compliance.
- Partner Profiles: Each partner listing provides an overview of their capabilities, specializations, office locations, and links to their website and case studies.
Pricing and Engagement Model
The Google Cloud Partner Directory is a free discovery tool and does not display partner pricing. Engagement begins by contacting partners directly through their profile to discuss project requirements and request a proposal.
A key benefit of using the directory is identifying partners who can help you leverage Google’s funding and incentive programs. Many specialized partners are adept at navigating initiatives like the Google Cloud Rapid Assessment & Migration Program (RAMP), which can provide funding and tools to accelerate your migration.
Expert Tip: During initial conversations with a partner from the directory, ask about their experience with Google Cloud RAMP. A partner’s ability to help you access these funding and support mechanisms is a strong indicator of their maturity and relationship with Google.
| Feature Summary | Google Cloud Partner Directory |
|---|---|
| Partner Focus | Google Cloud Specialized and Premier Partners |
| Cost Model | Free to use; must request quotes from partners |
| Key Advantage | Vetted partners with clear specializations; access to Google funding programs |

6. G2 – Cloud Migration Services category
For decision-makers who prioritize peer validation and user feedback, G2’s Cloud Migration Services category is an essential resource. As a large B2B services marketplace, G2 provides a review-driven platform to discover, compare, and shortlist migration partners. It aggregates real-world experiences from verified clients, offering a ground-level view of a company’s performance beyond marketing materials.
This platform is valuable for building an initial long list of vendors and for cross-referencing claims made by providers. By compiling reviews and ratings on factors like quality of support and ease of doing business, G2 helps you quickly gauge market reputation. This user-generated insight makes it one of the best sources for identifying cloud migration companies based on demonstrated customer satisfaction.
Key Features and User Experience
G2 turns a vast landscape of service providers into a manageable list through intuitive filtering and data presentation.
- Verified User Reviews: The core of the platform is its extensive library of reviews from authenticated users, which are often detailed and provide context on project scope.
- Grid and Quadrant Reports: G2’s proprietary “Grid” reports visually map market leaders, contenders, and niche players based on customer satisfaction and market presence.
- Targeted Filtering: Users can filter the list of providers by company size, industry focus, and geographic location to find partners with relevant experience.
- Direct Engagement: The platform facilitates direct contact, allowing you to request quotes or schedule introductory calls with shortlisted vendors.
Pricing and Engagement Model
G2 is a free-to-use platform for buyers. Pricing information for the listed cloud migration companies is generally not available on their profiles; you must engage with them directly to receive a proposal.
While G2 doesn’t offer direct funding programs, the information gathered from reviews can be a powerful negotiation tool. Insights into a provider’s typical client size, project complexity, and reported ROI from past customers can help you frame your requirements and budget expectations more effectively.
Expert Tip: Look beyond the overall star rating. Dig into the “highest-rated features” and “lowest-rated features” sections on a provider’s profile. These details often reveal specific strengths (e.g., project management) or weaknesses (e.g., post-migration support).
| Feature Summary | G2 – Cloud Migration Services |
|---|---|
| Partner Focus | Broad range from global integrators to niche boutiques |
| Cost Model | Free to use; must request quotes from vendors |
| Key Advantage | Transparent, verified peer reviews and market reports |

7. Clutch – Cloud Migration Services directory
For procurement teams and IT leaders focused on budget alignment and verified client feedback, Clutch’s Cloud Migration Services directory offers a data-rich platform. Clutch aggregates a broad spectrum of IT service providers, making it an excellent tool for comparing mid-market and boutique firms based on transparent, client-submitted reviews and project details. This focus on verified, first-hand client experiences provides social proof that is invaluable during vetting.
The platform’s primary value lies in its emphasis on practical business metrics like hourly rates and minimum project sizes. This allows decision-makers to quickly filter out vendors that don’t align with their budgetary constraints, making it one of the best cloud migration companies’ directories for organizations needing a partner within a specific financial scope.
Key Features and User Experience
Clutch is designed for efficient, budget-conscious vendor discovery. Its filtering system is tailored to procurement workflows.

- Geographic and Industry Focus: Pinpoint providers with a strong presence in specific cities or with documented expertise in your industry vertical.
- The Leaders Matrix: This feature visualizes a company’s “Ability to Deliver” against its “Market Presence,” offering a quick way to identify established leaders.
- Verified Client Reviews: Each review includes project context, costs, timelines, and direct feedback, providing a holistic view of the client experience.
Pricing and Engagement Model
Clutch is a free-to-use directory for buyers. The platform’s core benefit is its transparency around partner pricing models. Each listed company typically provides a range for their hourly rates and a minimum project size, which is valuable for initial budget planning.
Engagement happens directly with the shortlisted firms. After identifying potential partners, you must contact them to initiate a formal RFP or quoting process. A clear understanding of your goals is crucial before you engage with potential vendors; you can learn more about crafting a cloud migration strategy on CloudConsultingFirms.com.
Expert Tip: Pay close attention to the distribution and quality of reviews. A company with a dozen detailed, recent reviews from similar-sized businesses is often a safer bet than one with just a few vague, older testimonials. Use the “Sort by” function to view the most recent reviews first.
| Feature Summary | Clutch – Cloud Migration Services |
|---|---|
| Partner Focus | Broad market, strong in mid-market and boutique US firms |
| Cost Model | Free to use; providers list their rate and project size ranges |

Making Your Final Decision: An Actionable Checklist
You’ve reviewed the official partner directories, explored third-party aggregators, and now hold a shortlist of potential candidates. This final stage is where you transition from a broad search for the “best cloud migration companies” to identifying the single best partner for your business needs.
The right choice isn’t about finding a vendor to lift-and-shift servers. It’s about securing a strategic partner who aligns with business objectives, de-risks a complex technical project, and empowers your internal team. This checklist provides a structured framework to guide your final evaluation.
Step 1: Solidify Your Non-Negotiables
Before you engage in another partner conversation, your team must align on the must-haves.
- Compliance and Certifications: List the specific regulatory frameworks you operate under. Is HIPAA for healthcare data mandatory? Is SOC 2 Type II required? Does financial data necessitate adherence to PCI DSS? A partner without verifiable experience in your specific compliance landscape is a non-starter.
- Technical Platform Expertise: Be precise. Don’t just ask for “AWS experience.” Specify if you need expertise in Amazon RDS for a database migration, AWS Lambda for a serverless project, or Azure Kubernetes Service (AKS) for container orchestration.
- Geographic and Language Support: If your operations are global, you need a partner with a presence in key regions. Clarify requirements for 24/7 support, language capabilities, and understanding of local data sovereignty laws like GDPR.
Step 2: Move Beyond Logos to Relevant Proof
Every company will showcase client logos. Your job is to dig deeper for proof that relates to your project. Superficial case studies are a red flag.
Key Insight: A truly experienced partner won’t just send you a glossy PDF. They should be able to connect you with a relevant, non-competitive client reference who can speak to their experience, the project’s challenges, and the business outcomes.
During your evaluation, make these specific requests:
- Request Industry-Specific Case Studies: Ask for examples of projects completed for companies in your industry (e.g., FinTech, Manufacturing, Healthcare).
- Ask for Technically Similar Projects: Provide a high-level overview of your project’s complexity. Are you migrating a monolithic legacy application or a microservices architecture? Ask for examples of migrations of a similar technical scope.
- Inquire About Challenging Projects: This is a powerful question. A mature partner will be able to discuss a project that faced unexpected hurdles. How they identified the problem, communicated with the client, and navigated the challenge reveals more than a flawless success story.
Step 3: Evaluate the Knowledge Transfer and Empowerment Plan
The goal of a successful migration is not permanent dependency on a third-party firm. A great partner acts as a temporary accelerator and educator.
- Assess Their Training Methodology: Ask how they plan to upskill your team. Will they conduct formal training sessions? Do they offer paired programming? Is documentation clear and comprehensive?
- Clarify Post-Migration Support Tiers: Understand exactly what their post-migration support looks like. Is it a reactive, ticket-based system, or a proactive engagement? Define the handoff process and clarify responsibilities. The best cloud migration companies build a clear path to self-sufficiency for their clients.
Step 4: Issue a Targeted and Weighted RFP
A well-structured Request for Proposal (RFP) is your final tool for an objective comparison. Avoid long and generic RFPs. Focus on a concise document that forces partners to address your most important criteria.
Your evaluation scorecard should be weighted based on your priorities. A sample weighting might be:
- Technical Expertise & Proposed Solution (40%): How well do they understand the problem? Is their proposed architecture sound, secure, and cost-effective?
- Relevant Experience & Case Studies (25%): How closely does their past work align with your project?
- Cultural Fit & Project Management (20%): Do their communication styles and processes align with yours?
- Pricing & Value (15%): Does the proposal offer clear value for the cost?
By following this four-step process, you move from a list of possibilities to a confident, strategic decision. You select a partner not just for their technical skills, but for their ability to deliver value, mitigate risk, and empower your organization for success in the cloud.
