One of the questions we hear most frequently is “how do I get my data into the cloud?” For many organizations, the benefits of expanding on-premise data storage to include hybrid cloud storage have begun to resonate, but they struggle to get started as they determine how to get move data into the cloud. The decision on how to onboard initial data to the cloud, or what we call the initial ingest, is one that cannot be overlooked.
While there is more than one way to perform the initial ingest, it shouldn’t be a surprise that the best solution can vary on an individual case basis. Relevant factors influencing the decision include: amount of data intended for ingestion, amount of available bandwidth, timeframe in which you want to load the data. Typically, most organizations will decide on one of the following three methods for the initial ingest:
- Use existing bandwidth to perform the transfer over time
- Increase or “burst” bandwidth for the duration of the transfer
- Ship media directly to a cloud provider
Use existing bandwidth
Calculating how long it takes to upload a large amount of data across a WAN involves a bit of straightforward arithmetic. For instance, an uplink speed of 100Mbit/sec should be able to push nearly 1TB per day.
While this approach sounds cut and dry, in practice, organizations need to consider a few additional factors:
- Subtract typical WAN usage to more accurately calculate available bandwidth
- Employ bandwidth throttling and scheduling to minimize impact on existing applications
- Cache/buffer the data so they can continue to access data during the ingest process – sometimes starting with a large buffer and shrinking it over time
Temporarily increase bandwidth
For circumstances where existing bandwidth will not onboard data in the cloud in a timely manner, another option is to temporarily increase bandwidth during the upload process. Some telcos and internet providers offer bursting capability for short durations lasting weeks or months. Once the ingest completes, bandwidth can be restored as before to accommodate the normal course of data accesses and updates
An alternative to increasing bandwidth is using a temporary colocation or data center facility that has higher-bandwidth access to the cloud provider. This adds the additional costs of transportation, equipment setup and leasing but may offer a cost-effective compromise.
Physically ship media
Ultimately, if data cannot be onboarded in a timely manner via network (let’s say it’s a few PB in size), shipping physical media to a cloud provider is the next option. While this option may seem deceptively easy, it’s important not to ignore best practices when physical shipping media.
Whereas many organizations have adopted a “zero trust” model for their data already stored in the cloud (meaning all data is encrypted with a set of keys maintained locally), transporting data requires similar safeguards.
This week, TwinStrata announced the latest release of CloudArray, which includes a secure import process that encrypts and encapsulates data into object format stored in the cloud prior to shipping the data. Following the same security practice used for storing data online in the cloud eliminates security compromises that may lead to possible data breaches.
The bottom line
While there are benefits to expanding on-premise storage infrastructure with a secure, hybrid cloud strategy, often the starting point involves answering the question of how to get initial data there. Choosing the right option can both satisfy the need for timeliness while mitigating risks around security and disruption.
