loss as to how to move beyond using an online application like Salesforce.com, a cloud backup solution or a file sync-and-share option.
To take the next step in cloud adoption by moving important applications and data to the cloud, organizations first need to decide which workloads or data sets it might be better or more cost-efficient to have hosted by a cloud provider. Second, organizations have to decide how to get them there. When it comes to applications, Storage Switzerland suggests using a hybrid approach. An ideal starting point is when the organization decides to bring a new application online. Here are two cloud storage use cases that allow users to leverage the cloud in areas other than backup.
The application lifecycle use case
Traditionally, bringing a new application online means buying new servers and new storage. Oftentimes, these items are purchased to run the application and store its data after it is fully in production. The problem with this method is that it might take months or even years for the application to completely justify that original purchase of the hardware.
An alternative is to use the cloud by starting the application development there and leveraging compute and storage from the provider. Then, as the application matures, bring it into the data center to support full production. This allows you to delay the purchase of servers and storage, which will likely be less expensive since infrastructure costs typically decrease over time. It also means your final infrastructure decision will be better thought-out, as you will have more time under your belt with the application running.
This technique means you can leverage the cloud to migrate the application back as it hits the legacy state, potentially being replaced by another application. Often when this happens, users still need access to the old data contained within the legacy application, and the cloud is an ideal location for reference data.
The self-service disaster recovery use case
Many cloud backup providers have evolved their offerings to provide disaster recovery as a service (DRaaS). This means that they back up your data as usual, but then also enable you to recover that data and its application in their cloud. If your data center becomes unavailable, you can restart applications in theirs. But it is relatively easy to do this on your own as well.
There are applications that continuously replicate data from your data center to a cloud compute provider like Amazon, Google or Rackspace. While replicating, they also convert to that provider's virtual format. If your data center goes down, you can start those cloud instances up as needed. What's interesting is that many cloud providers charge a very nominal fee for this type of storage and charge for compute cycles only as they are used. This makes for a very inexpensive DR function, as well as a practical way to test and develop applications.
