You won’t find medical records or other healthcare data stored in hospital file cabinets much anymore. Technological advances have generated more secure, efficient means of housing that information. The problem is there’s a lot of data being generated in the healthcare industry these days. By “a lot,” we’re talking about zettabytes. Much of it is in the form of unstructured data courtesy of EHRs, medical device telemetry, better imaging and diagnostics capabilities, emerging technologies such as the Internet of Things, and other factors.
It’s hard enough storing the unprecedented amounts of data, much less doing so economically. Complicating things even more is the fact that healthcare organizations also must adhere to stringent regulatory requirements regarding data privacy and security protocols, how long the data must be retained and how quickly it can be accessed. Nonetheless, a surprising simple, cost-effective solution does exist: object storage.
Unlike traditional storage systems that organize data in files or blocks, object storage works with units of storage called objects. Objects are stored in buckets in a flat address space called a storage pool. When the object is stored, an ID is created for it so it can be located in the pool.
The objects aren’t restricted by a hierarchical file structure, so the number of object IDs can be increased for almost limitless scalability. Applications can quickly retrieve the right data through the object’s ID or by querying the metadata in the object using an HTTP-based REST application programming interface (API).
Every time an object changes, it is stored as a new object to prevent corruption through simultaneous changes. Object storage also employs erasure coding to help maintain data integrity. Similar to the way RAID works at the disk drive level, object storage restores lost or corrupted data by using redundant chunks.
Objects are also protected because multiple copies of data are stored over a distributed system. If a node fails, the data can still be made available. This addresses common issues including drive failures, bit-rot, server and failures, and power outages.
Object storage is ideal for use in the healthcare industry for a number of reasons, including:
Those types of data typically do not require low latency or high performance, but do need high resilience and durability against disk, node or site failures, and bit rot. That’s what object storage provides.
The data may not be needed often but with object storage, it can be accessed anytime and from anywhere — as long as there is an internet connection. It is also easy to search and locate data with object storage simply by using the object’s ID or by querying the metadata in the object using an HTTP-based REST API.
Another benefit to healthcare organizations is that they can conduct searches that return a set of files that meet specific criteria. For example, a typical X-ray stored as a file would have limited metadata associated with it beyond a name and the date it was created. Stored as an object, however, the X-ray could have rich metadata information such as the body area X-rayed, the injury type, the injury cause, the gender and age of the patient, etc. This makes it extremely useful and easy for users, such as physicians, to quickly retrieve specific information.
