Hot tiers are meant to store items that are needed for active work and must be accessed quickly and frequently. These tiers are generally referred to as hot, warm, cool and cold, with hot typically having the fastest access to files and cold having the slowest although there are other factors involved. That’s exactly why they offer different storage levels at varying costs based in part on the frequency at which data is accessed and how much is moved back and forth. Today’s cloud providers have recognized that not all cloud object storage systems serve the same purpose. This makes cloud object storage ideal for backup and long-term storage.
ED STORE OJECT STORAGE SOFTWARE
Without the extensive overhead of file and block storage, applications like backup software can use simple requests to store and retrieve objects across large and distributed storage systems. What object storage lacks in versatility it makes up for in simplicity. Instead of using a namespace and a directory structure, applications address objects based on an ID and a few simple HTTP API calls like PUT, UPLOAD, GET and DELETE. In an object storage system, objects can reside on any number of servers, whether on premises or in the cloud. But object storage is also the perfect place for backups – whether for disaster recovery or long-term retention for compliance. Objects may consist of image files, HTML pages, binaries, video, executables and user-generated content - mostly unstructured data that’s unlikely to change. Object storage is used to store and retrieve both structured and unstructured blobs of data as a whole, rather than as individual blocks. However, block storage depends on access to a running server with a file system, and its cost structure is tied to the entirety of space allocated, whether it’s all being used or not. The low latency of block storage is suited to databases and transactions where performance is a priority. In a storage area network (SAN), the SAN software can find, read and write data without the overhead of descriptions and user access privileges. File storage scales up reasonably well for accessing hundreds of thousands of files in a file system, but not for accessing billions of files in a backup repository.īlock storage works at the level of blocks, which use sector addresses instead of filenames and metadata. But all that convenience brings the overhead of file access privileges, file locking, copying and manipulation. A file system provides the namespace for identifying files and manages metadata like owner, modification date and size. A quick storage refresherīefore we talk about the advantages of using cloud tiers for long-term storage, let’s first have a quick refresher on the types of storage options offered by cloud providers.įile storage makes it easy for applications to find data on a network and retrieve it.

But a little bit of strategy can go a long way when it comes to cloud tiering for object storage. Cloud-based file, block or object storage? Private or public cloud? Amazon Simple Storage Service (Amazon S3), Azure Blob Storage or some other cloud storage provider? Cool or cold tier?īut while a critical need, nobody wants to think much about long-term storage – they just want cost-effective and automated backup/restore, disaster recovery and archiving. Then there are the infrastructure questions. Should you put it in the cloud and forget about it? That might seem more simple and less costly than on-premises storage, but it’s hardly care-free and it’s not always less expensive. Should you store your aging data on site? That keeps it close at hand, but at the high cost of infrastructure, maintenance, electricity, hardware, software and, most of all, your time. The need for long-term storage is driven by business imperatives that never stop growing - backup/restore, disaster recovery, audit readiness, regulatory compliance and more. While access and availability to today’s data is critical to keep business going, easy access to yesteryear’s data is just as important.

So how can you get the best of both worlds? To start, be sure you have the right data protection strategy and architecture in place. Cloud object storage and the strategic use of cloud tiering are hot trends for data protection, but you need to balance cost and speed for the best solution.
