However, OpenStack still faces some unstable factors in its future development. Insufficient bandwidth of WAN will pose a serious threat to the development of hybrid cloud. In the foreseeable future, data migration between private and public clouds will become a performance bottleneck. Coupled with the lack of some easy-to-install tools (this problem has just been improved), some IT departments are deciding whether to use the public cloud completely. Another factor that needs to be considered is that container technology improves work efficiency, which may affect the development of public cloud and prompt enterprises to adopt pure private cloud.
Whether these negative factors can cause enough harm to private cloud to change the market trend is still unknown, and the rise of container technology may promote the continuous development of OpenStack. In my opinion, neither of these situations will happen. I think OpenStack will still be a private cloud and hybrid cloud platform, because the whole industry has invested heavily in OpenStack.
