A cloud consulting company is a professional services firm that plans, migrates, builds and often operates workloads on public cloud platforms such as Amazon Web Services (AWS), Microsoft Azure and Google Cloud on behalf of client organisations. Engagements typically run from assessment and migration to data, cost management and generative AI work.
Each of the three large platforms runs a tiered partner programme in which consultancies earn higher tiers by passing audits, accumulating certified staff and demonstrating delivered projects. The top tiers (AWS Premier Tier Services Partner, the Microsoft Azure Expert Managed Service Provider designation and Google Cloud Premier Partner) are the most widely used public signal of a firm's depth on a given platform, and they form the basis of this list.
This list covers cloud specialists and the cloud units of larger groups, rather than general IT outsourcers ranked by total revenue. Several of the best-known specialists have been bought in recent years, so entries carry their current operating names: Nordcloud belongs to IBM, SADA to Insight Enterprises, Mission to CDW, and Trek10 has been absorbed into Caylent.

What cloud consulting companies do
Cloud consultancies sit between the platform vendors and the client. The work usually falls into four phases: an assessment of the existing estate and a business case; the design of a secure account or subscription structure, often called a landing zone; migration and modernisation of applications and data; and run-phase services such as cost optimisation, security monitoring and managed operations. Many firms in this list now sell all four, which is why several describe themselves as both consultancies and managed service providers.
Firms differ mainly in platform focus. Some, such as Caylent and Mission, work only on AWS; others, such as 66degrees and SADA, grew up as Google Cloud specialists; and a smaller group, led by Nordcloud, holds top-tier status on all three major platforms.
How hyperscaler partner tiers work
AWS ranks services partners in tiers, with Premier Tier the highest and Advanced Tier below it; progression depends on the partner's certified staff and delivered customer work. Microsoft's Azure Expert MSP is an audited designation for managed service providers rather than a general tier. Google Cloud's Premier level sits above its standard partner level and is normally paired with specialisations in areas such as data analytics, infrastructure or machine learning.
Tiers and specialisations are re-assessed periodically and the names change. Older press releases cited in this list still use superseded names such as AWS Premier Consulting Partner or Microsoft Gold partner, which is noted in the relevant entries.
Methodology
Firms were included if they present cloud consulting or migration as a core line of business and if at least one top-tier hyperscaler partner status could be confirmed on a page opened during research in November 2026: the firm's own website or press release, or its parent company's investor release. Partner directories operated by AWS, Microsoft and Google were not machine-readable at the time of review, so statuses are as published by the firms themselves, with the date of the publishing page where it is older than 2025.
Entries are ordered by three keys, applied in sequence. First, the number of the three platforms on which the firm holds the top published tier (AWS Premier Tier Services Partner; Microsoft Azure Expert MSP; Google Cloud Premier Partner). Second, the number of remaining platforms on which the firm publishes a named lower tier (for example AWS Advanced Tier). Third, the earliest documented start of the business, with the oldest first; where the firm is the product of a merger or acquisition, the start year of the earliest predecessor or acquired unit named by the company is used.
The method measures breadth of verified platform credentials, not quality of delivery, price or client satisfaction, none of which can be verified from public primary sources. A single-platform specialist may be the stronger choice for a single-platform project. Large general IT outsourcers, which are covered in a separate revenue-ranked list of managed service providers, were excluded.

Solutions integrator combining an Azure Expert MSP practice with SADA's Google Cloud unit
Best for: Organisations standardising on Google Cloud or Azure that also buy licences and hardware
Insight Enterprises completed its acquisition of SADA, one of the largest dedicated Google Cloud partners, on 1 December 2023. SADA, which has served customers since 2000, brought about 850 professionals working in the Google Cloud ecosystem, Google Cloud Premier Partner status, 10 Google Cloud specialisations and six Google Cloud Partner of the Year awards.
At the time of the deal Insight itself was an Azure Expert Managed Service Provider with 22 Microsoft specialisations and more than 65 Microsoft Partner of the Year awards, and an AWS Advanced Tier Services partner holding the Migration, Microsoft Workloads, DevOps and Security competencies. The combination gives Insight top-tier credentials on two platforms and a named tier on the third, although the AWS status cited here dates from December 2023.

Fully remote multicloud partner combining consulting with cost-management software
Best for: Digital-native companies on AWS or Google Cloud focused on cost control
DoiT, founded in 2011 and formerly known as DoiT International, combines cloud consulting and support with its own cloud cost and operations software. Its partner page lists it as an AWS Premier Tier Services Partner and a Google Cloud Premier Partner, and as a Microsoft Gold Solutions Partner, a designation from Microsoft's earlier partner programme.
The company says it has more than 4,500 customers and describes itself as globally distributed and fully remote rather than naming a headquarters. Its Google Cloud page highlights a 2023 Google Cloud Partner of the Year award for sales in Israel. DoiT's model suits software and digital-native companies that want ongoing access to cloud architects and cost analysis, rather than a fixed-scope migration project.

Frequently asked questions
What does a cloud consulting company do?
A cloud consulting company helps an organisation move to and use public cloud platforms. Typical work includes assessing existing systems, designing a secure account structure, migrating and modernising applications and data, and setting up cost and security controls. Many firms also offer managed services after migration, operating the environment on the client's behalf under an ongoing contract.
What is an AWS Premier Tier Services Partner?
It is the highest tier of the AWS Partner Network for consulting and services firms. Partners progress through the tiers by building up certified staff and delivered customer work, and status is reviewed over time rather than granted permanently. In this list Nordcloud, DoiT, Slalom, Presidio, AllCloud, Caylent and Mission publish Premier status.
Which cloud consulting firms are top tier on AWS, Azure and Google Cloud?
Among the firms reviewed, only Nordcloud, part of IBM, publishes the top tier on all three platforms: AWS Premier, Microsoft Azure Expert MSP and Google Cloud Premier Partner. Insight holds the top tier on Azure and, through SADA, on Google Cloud, while DoiT holds Premier status on both AWS and Google Cloud.
Who owns SADA and Mission Cloud?
SADA, a long-standing Google Cloud Premier Partner, is owned by Insight Enterprises, which completed the acquisition on 1 December 2023. Mission Cloud Services, an AWS Premier Tier Partner, was acquired by CDW in a deal announced on 2 December 2024 and operates as CDW's dedicated AWS practice. Both continue to use their own brand names.
Is a specialist or a large integrator better for cloud migration?
It depends on scope. Specialists such as Caylent, Mission or 66degrees concentrate their certified staff on a single platform and are often chosen for focused migration or data projects. Large integrators and multicloud firms suit programmes spanning several platforms, countries or business functions, or where cloud work is bundled with outsourcing, licensing or hardware.
