Sponsored DevOps has never been more important, but the dominance of a few public cloud platforms and code repositories have posed developers with a choice. Is it better to adopt a single-vendor DevOps toolset in the hope of better integration, or to choose best-of-breed tools from multiple vendors?

There are compelling reasons to take the latter approach, not only because of the excellence of specialist tools, but also to avoid the risk of lock-in to a specific platform. History tells us that lock-in, where it succeeds, results in higher prices and reduced innovation. Companies that create an effective lock-in tend to keep prices high and licensing complex and expensive, knowing that their customers have no easy way to move elsewhere.
