Experiences from building a cross-cloud orchestration tool

Even after being around for almost a decade, the cloud still has tremendous complexity and suffers from vendor lock-in. Users still face poor comparability of performance and quality of service of different operators. This still hinders users of all kinds to take full advantage of clouds and even more of cross-cloud deployments. While multiple tools exist promising to address all those issues, they still lack fundamental features. Based on an analysis of existing tools, we introduce Cloudiator, an open source software, addressing existing issues in cross-cloud orchestration and depict our experiences and insights gained while designing and implementing it.
