Published in Linode Cube·Feb 16, 2017Distributed File Systems and Object Stores on Linode (Part 3) — HDFSIn part 1 of this series, we looked at GlusterFS. In part 2, we looked at the Ceph Object Store. In this concluding part, we look at HDFS which is arguably the most popular among the three in big data ecosystems and is also quite different from the other two. …Big Data6 min readBig Data6 min read
Published in Linode Cube·Feb 8, 2017Distributed File Systems and Object Stores on Linode (Part 2) — CephIn part 1 of this series, we looked at GlusterFS. Now in part 2, we look at an entirely different kind of storage system - the Ceph Object Store. Ceph is actually an ecosystem of technologies offering three different storage models — object storage, block storage and filesystem storage. Interestingly…Cloud Computing10 min readCloud Computing10 min read
