The never-ending cloud marketing chatter continues to obscure the distinctions between traditional storage systems and public, private and hybrid cloud storage technology. This confusion is common in any tech market when a paradigm shift takes place. Muddying the waters gives established vendors time to acquire successful startups or develop their own technology to meet the new demand.
This SearchCloudStorage.com three-part expert video tip series, by Dragon Slayer Consulting founder and senior analyst Marc Staimer, explores ways to implement hybrid cloud technology, and the pros and cons associated with each approach. Why a hybrid cloud? Because it provides immediate cloud storage benefits while increasing performance, local control, manageability and flexibility.
Cloud storage delivers functionality and capabilities designed to solve demanding storage problems such as:
- Simplifying massive amounts of passive data from dozens of petabytes to exabytes, and even zetabytes and trillions of files/objects in a single storage container.
- Scaling access and performance that maintains a lockstep with capacity growth.
- Taking distributed geographic locations out of the planning picture while maintaining geographic awareness.
- Ensuring stored data is highly resilient and self-healing, with enduring persistence for years, decades and even centuries.
- Enabling multiple tenants privately and securely.
- Empowering user self-service and policy-based capacity/performance on demand.
- Changing the way storage is bought and paid for by charging only for the actual storage used in arrears versus charging upfront for all the storage system’s unused raw storage.
- Ending disruptive technology refreshes and data migration.
Public cloud storage is offered by cloud service providers. Data is kept off site in a service provider’s data center or in multiple data centers in various locations on a pay-per-stored-gigabyte basis. Public cloud storage is a perfect remote repository for passive or distributed data with infrequent user access.
But public cloud storage comes with performance issues. The biggest problem is the latency involved in moving data to and from a service provider’s storage cloud. While private cloud storage solves the distance latency issue, it's limited to private data centers and/or infrastructure-as-a-service supplier data centers if utilized. That's where hybrid cloud storage enters into play. Hybrid cloud storage technology combines the best of private and public clouds by delivering local performance, plus all the benefits of public cloud storage.

Connecting a private cloud to public cloud storage is referred to as a federated cloud, and a project such as this can provide a cost-effective way for environments to store passive data inexpensively and efficiently. Learn the pros and cons of a federated cloud approach in this video tip.
Staimer details three different ways to integrate local storage with a public storage cloud: primary storage integration, gateways for backup and volume manager integration. Find out what each approach has to offer.
Pull a public storage cloud into a private data center for all the advantages of a public cloud, but none of the interruption or performance drops associated with moving data over a WAN. Creating a public storage cloud extension into a private data center is ideal for IT environments that require the convenience and performance of locally stored data, but off-site management capability.
