Disclosure: I&#x27;ve been working with Tutum since the initial team.<p>Tutum was actually a container hosting service at first but we found there were a ton of technical challenges in multi-tenancy with hundreds&#x2F;thousands of containers and it&#x27;s hard to build a level of trust that larger IaaS providers have like AWS.<p>Hosting puts you in direct competition with IaaS providers, while being a middle-man can provide more value-add and you get to work with the other providers to strengthen your solution.
