Gateways Will Accelerate Data Migration To The Cloud

The last few days have been eventful in the cloud gateway space and should provide I&O organizations more incentive to start evaluating gateways.  Yesterday, EMC announced its acquisition of cloud gateway startup TwinStrata which will allow EMC customers to move on-premise data from EMC arrays to public cloud storage providers.  Today, Panzura launched a free cloud gateway and their partner Google is adding 2TB of free cloud storage for a year to entice companies to kick the tires on a gateway.  Innovation and investment in this area does not appear to be slowing down.  CTERA locked in an additional $25 million in VC funding last week to accelerate the sales and marketing efforts to support its cloud gateway and file sync & share products.
 
Though the cloud gateway market has grown slowly so far, this technology category is about to become mainstream.  Cloud Gateways are disruptive since they can facilitate data migration from on-premises to a public cloud storage service to create a true hybrid cloud storage environment.  Basically, a cloud gateway is a virtual or physical storage appliance which looks like a NAS or block storage device to users and applications on-premises, but can write data back to a public cloud storage service using the native APIs of that cloud.  
 
A number of use cases have emerged for cloud gateways including:
