How Data Modernization companies map to modernization approach

Rows group data 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 27 of 34 companies in data modernization. Product vendors and delivery firms both cluster in Replatform.

Engagement bands in this domain

Small: $40K–$80K
Mid-market: $100K–$200K
Enterprise: $250K–$500K

Spans are the published pricing tiers on this domain’s service pages (Data Governance Strategy & Implementation), 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.

AWS Database Migration Service (DMS)
Platform
Amazon's managed replication service moves relational databases, NoSQL stores, and data warehouses into AWS while the source keeps serving production traffic, using change data capture for both homogeneous jobs like Oracle to Oracle and heterogeneous ones like Oracle to Aurora PostgreSQL — it moves data, not schema.

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 (28 profiles) and specialty evidence (34), then narrow by team size (25) and location (25). 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.

Data modernization suppliers divide into platforms and delivery partners. Platforms provide warehouses, lakehouses, integration, transformation, governance, catalog, and master-data capabilities; consultancies and integrators assess the estate, redesign data models, migrate pipelines, remediate quality, and establish governance. Compare platforms by workload fit, openness, interoperability, security, and lifecycle cost. Compare partners by source-system experience, data-quality methodology, industry controls, migration evidence, team capacity, and location. Use the alphabetical roster as a fit-based evaluation set, not a ranking.
