Hybrid Cloud Blog


Last week we published experts from Chapter 7, the final chapter in Rethinking Enterprise Storage:  A Hybrid Cloud Model. This week we provide a few final thoughts and a glossary of terms for hybrid cloud storage.  Over the past several weeks on this blog, we published excerpts from each chapter of this book via a series of posts. We think this is valuable information for all IT professionals, from executives responsible for determining IT strategies to administrators who manage systems and storage. We would love to hear from you and we encourage your comments, questions and suggestions.

We also want to remind you that the Microsoft StorSimple 8000 series provides to customers innovative and game-changing hybrid cloud storage architecture and it is quickly becoming a standard for many global corporations who are deploying hybrid cloud storage. You can learn more about the StorSimple 8000 series here:  www.microsoft.com/storsimple

Here are the chapters we have excerpted in this blog series:

Chapter 1                              Rethinking enterprise storage

Chapter 2                              Leapfrogging backup with cloud snapshots

Chapter 3                              Accelerating and broadening disaster recovery protection

Chapter 4                              Taming the capacity monster

Chapter 5                              Archiving data with the hybrid cloud

Chapter 6                              Putting all the pieces together

Chapter 7                              Imagining the possibilities with hybrid cloud storage

That’s a Wrap!                     Summary and glossary of terms for hybrid cloud storage

We hope you found the information in this blog series both educational and informative and so, without further ado, here is a glossary of terms for hybrid cloud storage found in Rethinking Enterprise Storage – A Hybrid Cloud Model
