Hybrid Enterprise Cloud 
Storage Architecture
With the advent of cloud computing, it is inevitable for enterprises to increase their investments in cloud 
services. However, enterprises are reducing IT expenses to maximize the return on investment (ROI). In 
addition to controlling rising costs, IT administrators must take many considerations when facilitating 
cloud environment. They need to incorporate new technology into existing systems without impacting the 
stability and performance of the system and user experience. Studies have shown that businesses opt for 
hybrid clouds that can integrate with an existing environment and adapt to changing business needs at the 
same time. In fact, more than three-quarters (76%) of IT decision makers, business users and cloud vendors 
expect hybrid clouds to be the core of their cloud strategies, overtaking public and private clouds in the 
next five years. 
As enterprises migrate to cloud infrastructure for better agility and scalability, they are confronted with 
several challenges. Complying with high standards of evolving regulations, providing sufficient computing 
resources and controlling long-term operating costs are among the major challenges. This is why so many 
private cloud solution providers build their products with the provision of interoperability, virtualization 
capability, and scalability.
Interoperable solutions provided by the edge cloud devices that sit in between the public and private 
clouds can be leveraged to provide connectivity and data exchange capability with resources and 
management services running in the public cloud. As many organizations adopt the hybrid cloud storage 
architecture that spans on-premises enterprise storage and cloud storage services, edge cloud devices 
will play a key role in the deployment process. The following picture depicts that edge cloud devices help 
realize the communication of management and resources information with cloud services across the hybrid 
cloud boundary.
2015 will see a trend of deploying a hybrid cloud in businesses to optimize daily operations. We noticed 
a gap between high-end storage solutions designed for data centers and budget versions for the same 
purpose,” said David Tsao, product manager of QNAP. “With the release of the TVS-ECx80+ Edge Cloud Turbo 
vNAS, QNAP is filling the gap with a cloud storage solution with high-standard hardware designs and an 
economical price.
