In most real-world DevOps and IT strategy discussions, only three main approaches are commonly used. While
"Greenfield" and "Brownfield" are the standard industry terms, Bluefield is the only other major contender, especially in large-scale enterprise environments.The "Big Three" Most Used Approaches
- Brownfield (Most Common): The majority of enterprise projects (~44%) follow this path. It focuses on upgrading or migrating existing systems with minimal disruption, retaining legacy data and configurations.
- Bluefield (Hybrid): This selective approach is nearly as popular as Brownfield (~42%) in complex enterprise migrations. It allows teams to "pick and choose"—starting fresh with modern architecture (Greenfield) while selectively migrating high-value data and proven processes from old systems.
- Greenfield: Used by about 14% of organizations, this is the "clean slate" approach. It is the standard for startups or new product units that have no legacy technical debt and want maximum innovation potential.
Summary of Popularity
| Approach |
|---|
| Popularity Share | Best For... | |
|---|---|---|
| Brownfield | ~44% | Faster time-to-market and lower risk. |
| Bluefield | ~42% | Complex migrations needing both innovation and legacy data. |
| Greenfield | ~14% | Complete process overhauls and brand-new products. |
Note:
Other terms like "Greyfield" or "Whitefield" are rarely used in
standard DevOps practice and are usually confined to niche academic or
real-estate-based metaphors [No primary source cited for high DevOps
usage].
