OpenStack Swift is a storage project in OpenStack, which realizes a highly scalable and robust object storage, with low operational cost.
We, cloud storage team in NTT DATA, have been offered many projects aiming to replace legacy storage to swift, to store more data more safely with lower cost. In those project, we were often required not to change the existing systems. However, this requirement causes a problem in our integration, when they are so "legacy" that they rarely support REST API. Many systems are still on the way to turning to cloud-native architectures (like REST API), and we have seen many demands to introduce cloud system into no-cloud system, as the first step for ther turning.
In this session, we will explain some example cases from our Swift projects and how we solved this interface problem to intergrate Swift, very useful cloud technology, into the existing "legacy" systems.
- Example of user requirement and solution about integrating legacy system and Swift
- Some basic points and ideas to integrate Swift into existing systems
