More and more organizations are implementing some form of cloud data storage into their environment. Results from Storage magazine's fall 2012 storage Purchasing Intentions survey finds 29% of respondents use cloud storage services for non-backup applications. According to Storage Media Group editorial director Rich Castagna, who crunched the numbers from that survey, that's approximately double the number of organizations reporting cloud storage use back in 2010.
When asked about their cloud planning priorities, data backup topped respondents' lists. Collaboration/file sharing, disaster recovery, primary storage and data archiving rounded out the list of ways that users plan to interact with the cloud.
For data storage managers faced with questions around cloud storage, this cloud planning guide highlights the "must-know" information surrounding the technology. What's the best cloud data storage option for your environment? What questions does a cloud storage provider need to answer and what guarantees do you need from a service-level agreement before you sign on the dotted line? What differentiates cloud storage pricing from traditional data storage pricing? Do you need to perform backup and recovery now that your data is in the cloud? Can you keep everything in the "limitless" cloud or should you have a cloud-based storage policy? All these questions and more will be answered in this cloud storage implementation planning guide.

Which cloud storage option should you choose?
Now that you've made the decision to institute cloud storage in your environment, what type of cloud storage option should you choose? If you don’t have the time, staff or budget to manage your own internal cloud storage and have large amounts of data that rarely changes or isn't accessed very often, a public storage cloud might be for you. Public clouds are managed by a variety of cloud service providers that charge monthly usage fees for data access and data transfer. For organizations that need to maintain strict performance and security levels, a private storage cloud offers more control over data because the cloud infrastructure remains in-house. For companies that want the best of both worlds, a hybrid storage cloud keeps frequently accessed information on site and moves inactive data to the cloud for safekeeping.

How to evaluate a cloud storage provider
A cloud provider is a third-party firm that allows users and companies to store information at a remote data center and access it via an Internet connection. But before you turn your valuable data over to a cloud storage provider, you need to evaluate the provider's security processes, pricing, the various types of services offered, regulatory compliance and then firmly outline who owns the data in case you want to move it somewhere else in the future.

Negotiating your cloud storage SLA
Now that you've chosen a cloud provider, you need to delve into the cloud storage service-level agreement (SLA) that's offered. Most cloud SLAs spell out the uptime guarantees on offer -- usually a 99.999% guarantee -- and what recourse users have if those guarantees aren't met. But they do not cover the finer issues of data security and encryption, data privacy, geographic restrictions on where your data is stored, and business continuity issues in case of a disaster. You can negotiate these cloud storage SLA service terms with some cloud providers, but it could affect your cloud storage pricing.

Cloud storage pricing: Watch your bottom line
Pricing remains one of the biggest considerations when conducting your cloud planning. While traditional data storage requires storage managers to buy huge amounts of storage that may end up going unused, cloud storage pricing offers a pay-as-you-go model that allows companies to control costs. And because cloud storage is service based, organizations don't need to buy, manage and maintain storage hardware or undergo technology refreshes, which means reduced administrative costs.

Cloud storage backup: Best practices and choosing a cloud backup service
Cloud backup is when an organization moves data to an offsite managed service provider for protection. When choosing a cloud backup service, check on what platforms the provider supports, how the data is stored, whether or not data is replicated and if you're allowed your own encryption keys. In addition, see if the cloud backup provider offers a cloud seeding option to get that first batch of data to them.

Cloud disaster recovery explained
Disaster recovery (DR) services are a good match for the cloud because you don't need to keep a hot, warm or cold disaster recovery site on standby to replicate items back to the primary site in case of an emergency. But cloud DR does have its challenges, and security usually tops the list. Another major cloud planning concern is bandwidth, because you'll need to access your cloud data via an Internet connection. Anyone instituting cloud storage should therefore create a cloud disaster recovery plan that spells out procedures and costs.
