Approach matrix

How Cloud Modernization companies map to modernization approach

Rows group cloud modernization companies by modernization approach, defined in our 7 Rs of application modernization framework; columns separate product vendors from delivery firms.

Replatform is the most common approach here, documented by 33 of 51 companies in cloud modernization. Product vendors cluster in Rehost and Replatform; delivery firms in Replatform.

What each company delivers in cloud modernization

One entry per company, carrying only attributes we can point at a source for. Where a company has no published evidence for an attribute, nothing is shown rather than a placeholder.

Engagement bands in this domain

Small: $30K–$400K
Mid-market: $80K–$1.5M
Enterprise: $200K–$3M

Spans are the published pricing tiers on this domain’s service pages (Cloud Cost Optimization Services (FinOps), Cloud Readiness Assessment & FinOps Strategy, Kubernetes Migration Services), cross-checked against the cost benchmarks. A company is placed in a band by its team size — this is a statement about the size of engagement firms of that scale typically deliver here, not a rate card. We publish no per-vendor rates.

Companies to evaluate for Cloud Modernization

Scope: published cloud modernization companies with documented category, migration-path, or service evidence in this research domain.

Last evaluated 4 August 2026

208

Published modernization companies reviewed

Companies shown for cloud modernization

Platforms 7Consultancies & integrators 44

Inclusion criteria: A company must have a published profile and documented category, migration-path, or service evidence in this domain. See the evidence threshold in our research methodology.

How to choose: Start with documented buyer fit (44 profiles) and specialty evidence (51), then narrow by team size (36) and location (36). Open a profile to verify the underlying experience before shortlisting.

This is an alphabetical market map, not an ordinal ranking. Paid Featured placements are labeled and do not imply a recommendation.

Cloud modernization buyers encounter three supplier groups: hyperscale cloud platforms provide the target infrastructure and managed services; global systems integrators coordinate large, multi-region programs; specialist consultancies handle focused architecture, migration, platform-engineering, or FinOps work. Compare cloud platforms by workload fit, service maturity, compliance, data gravity, and commercial commitments. Compare delivery firms by cloud certifications, migration evidence, operating-model capability, team scale, and location. The alphabetical roster supports evaluation by fit rather than an ordinal ranking.
