GCP has been steadily gaining in functionality and popularity. Google Cloud Storage offers unified object storage for IT enterprises, from live data serving to data analytics and machine learning to data archiving. GCP has Coldline storage for data your business expects to touch less than once a year, and Nearline storage for data you expect to access perhaps a few times throughout the year. Both options are available with sub-second access speeds!
And now, GCP has launched IceCold Storage. It is currently priced at ~$15 / TB / year. At this price point, deleting data practically makes no sense, and it really begs the question of why not use it to keep a copy of all your data on IceCold storage just for redundancy and disaster recovery purposes. But how can you seamlessly leverage this incredibly low-cost storage option? Especially how can you use it without disrupting users or applications?
Enter Komprise. Komprise software will actively archive and replicate data to the Google Cloud without disrupting users and applications. Coupled with GCP storage, it will automatically identify and move cold data by policy from any NAS to GCP storage without disruption. Data that Komprise moves still appears to users normally. When they or an application accesses this data, Komprise automatically recalls the data, preventing any disruption. In some cases, moving this cold data to Cloud Storage can reduce your on-prem storage costs by as much as 70%.
Komprise consists of a grid of one or more virtual appliances that are deployed on hypervisors in the data center. Install and point Komprise at the NAS shares that you want to analyze and manage. You then let Komprise create simply management and capacity-planning decisions to move and replicate data to GCP. Komprise preserves the directory structure as well as file attributes on the target, unlike other cloud migration tools that strip data off file attributes and move blocks to the cloud that can only be accessed and understood using the application going forward. With Komprise, end users can continue accessing files with no change to their processes, because the location of data is transparent to them.
You can use their ROI tool to enter costs specifically for your environment to determine your projected savings. Depending on which Cloud Storage class you want to use: Regional, Multi-Regional, Nearline, or Coldline, or IceCold, you can modify the cost model to reflect the savings that you can realize after moving data.
What about performance of storage during data moves? Well, Komprise is invisible to the hot data path and does not get inline. Additionally, Komprise adaptively throttles back when the storage systems are in active use so that Komprise analytics runs non-disruptively in the background. As a result, the performance of the active data is unchanged and may even improve as the primary storage becomes less overloaded.
It also provides the ability to bulk recall data from all tiers of storage in the cloud and has added cost control and throttling when restoring data back to on-premises. Combined with the cost efficiency of GCP storage, you can save substantially on on-premise storage, DR, and backup costs.
