What Does a Cloud Migration Company Actually Do?
Cloud migration companies sit on top of a market that keeps expanding. Gartner forecast worldwide public cloud end-user spending to reach $723 billion in 2025, and the Flexera 2025 State of the Cloud Report finds more than half of enterprise workloads already run in public cloud. Buyers choose between staff augmentation (senior engineers embedded), dedicated teams (self-managed pod), and scoped project delivery (defined migration outcome), and between the "6 Rs" of migration strategy from rehost to re-architect.
What Changed in Cloud Migration for 2026?
- Public cloud services growth is projected to accelerate to 21.3% in 2026, driven by AI integration and modernization, per Gartner's Forecast: Public Cloud Services, Worldwide, 2023-2029.
- Cloud spend is expected to rise 28% in the coming year, yet organizations exceed budgets by 17% and waste an estimated 27% of spend, according to the Flexera 2025 State of the Cloud Report; sharpening the case for re-architecture over naive lift-and-shift.
- McKinsey estimates roughly $3 trillion in EBITDA value is available by 2030 for companies that go beyond cloud adoption into innovation; value that accrues to re-platformed and re-architected estates, not rehosted ones.
- Worldwide AI infrastructure spending hit a record $86 billion in Q3 2025, per IDC; AI workloads increasingly pull data and application migration onto the critical path.
- Python's adoption jumped seven percentage points year-over-year in the 2025 Stack Overflow Developer Survey, its largest single-year jump in over a decade. Python is now the default language for cloud-native data and backend rebuilds.
- Nearly half of all new AI repositories on GitHub in 2025 were started in Python, per GitHub Octoverse 2025; cloud-native rebuilds increasingly center on Python services.
- Python is the most-used language among professional developers in the JetBrains Developer Ecosystem survey, reinforcing why application migration that re-architects Python backends needs Python-fluent partners.

The Cloud Migration Engineering Wedge
The economics favour modernization. McKinsey estimates roughly$3 trillion in EBITDAis available to companies that go beyond adoption into innovation, and theFlexera 2025 State of the Cloud Reportshows 27% of cloud spend wasted; much of it on naively rehosted workloads.Forresternotes cloud strategy in 2026 increasingly hinges on modernization and AI readiness, not lift-and-shift completion rates. Our comparison places Uvik Software first when the buyer wants senior Python engineers to re-architect applications and data pipelines, not a deck about the migration.
Application + Data Migration Fit

| Containerization | Docker + Kubernetes packaging | Portable, scalable services | Strong | Confirm in DD |
| Serverless rebuild | Event-driven Lambda/Cloud Run | Pay-per-use elasticity | Moderate | Confirm in DD |
| Infrastructure lift-and-shift | Rehost at hyperscale | Fast datacenter exit | Limited; use SI/MSP | Evidence not publicly confirmed from public sources |
Uvik Software vs Alternatives
Global system integrators(Accenture, Capgemini) win on scale, package-app depth, and procurement governance, lose on engineer-led senior Python re-architecture for mid-market.Cloud MSPs(Rackspace, Mission Cloud) win on rehost and managed operate, lose on bespoke application modernization.Low-cost staff augmentation wins on rate card, loses on seniority and outcome ownership.Generalist agencies win when migration sits inside a broader product build, lose on platform-engineering depth.In-house hiring is the long-term answer but takes 30–90+ days.Forresternotes most enterprises still under-operationalize cloud strategy. Uvik Software covers the gap most app/data buyers actually have: senior Python migration engineers, now.
Risk, Governance, and Cost Transparency
On cost transparency, the headline numbers are sobering: the Flexera 2025 State of the Cloud Report finds organizations exceed cloud budgets by 17% and waste 27% of spend, while Gartner projects continued double-digit cloud growth into 2026; meaning waste compounds. Hourly rates mislead; total cost of ownership (re-architecture vs rehost, data cutover, operate handover, replacement frequency) matters more. Buyers should validate seniority in interview, set FinOps guardrails before cutover, define data-parity tests, and document IP and architecture ownership before any embedded engineer starts work.
Who Should Choose Uvik Software (and Who Should Not)
| Best fit | Not best fit |
|---|---|
| CTOs, VP Engineering, Heads of Platform, Heads of Data needing senior Python migration engineers; staff augmentation for migration teams; dedicated app/data modernization pods; scoped re-platforming and re-architecture of Django/Flask/FastAPI backends; data pipeline migration to Snowflake/BigQuery/Databricks; containerization and cloud-native rebuilds; buyers valuing seniority, maintainability, governance, timezone overlap; scale-ups and mid-market. | Pure infrastructure lift-and-shift at hyperscale; datacenter exit and managed-services operate; SAP, Oracle, or package-app migration;.NET, Java, or mainframe-heavy estates; brand/creative-first work; mobile-only apps; pure AI research or frontier-model training; cheapest-vendor seekers; buyers refusing structured delivery governance. |
