#207 – AWS Gets a SAN Upgrade

Chris EvansCloud, Storage Unpacked Podcast

This week the team is back after a short break and ready to talk all things cloud – or at least about Elastic Block Store. AWS recently announced io2 and io2 Block Express, the first new EBS block storage offerings for eight years. With such a long gap since io1 was first released, what has AWS been up to and what’s new? In this discussion, Martin and Chris question whether AWS is aiming to meet the requirements of enterprise customers that simply want to lift and shift their infrastructure into the cloud. Alternatively, the effort involved in rolling out a new distributed storage platform is significant, so this could be all about time and effort.
