Top Storage as a Service Providers 2021

Storage-as-a-Service (STaaS) has only been with us for a little more than a decade, but it is hard to find someone who isn’t using it. Whether it’s via Microsoft OneDrive on their home computer, iCloud for their phone, or Dropbox, most people are using some form of online storage. And, many are using a lot of it, including entire businesses. 

These days, online storage is being offered at excellent rates. Relatively small amounts of storage are given for free, and then most providers offer multiple tiers. From instantly available high-performance storage at the highest rates, service tiers grade down to lower performance and slower retrieval. The bottom, archival tier is very cheap with longer retrievals. 

As well as performance and retrieval pace, the volume of storage can factor into costs as can the degree of security, availability, and other service guarantees. Put simply, the more data you want to be able to retrieve faster and with the highest possible degree of security, the more it is going to cost. 

Unfortunately, more than a few companies have been burned by the allure of cheap online storage by not doing their homework. They dump it all online without reading the small print. Then they decide to migrate the data or bring it all back inhouse and suddenly the costs spiral out of control. Therefore, it is important to select a provider that fits your usage profile and budget.

Storage-as-a-Service Use Cases

STaaS has a variety of use cases. These include: 

  • Centralized storage of primary enterprise data 
  • Backup of enterprise data 
  • Disaster recovery of enterprise data 
  • Archiving of older or inactive data
  • Temporary data sets made available for testing, research, or other short-term purposes
  • Sudden increases in capacity due to seasonal or unusual spikes in usage. 

Selection Tips for Storage-as-a-Service 

Those purchasing Storage-as-a-Service are advised to select carefully based on the following: 

  • Start small. Use a relatively small amount of storage from a few provider candidates to determine how costing actually works out in the real world.
  • Determine your precise usage needs. Select the tier and service level that most closely matches your needs. If you do move data around, it may be best to pay a higher rate for storage if it comes with easier data retrieval and migration.
  • Avoid long-term contracts. Storage-as-a-Service vendors often adjust their rates. Lower rates may appear at any time and price wars are common.
  • Conduct a complete cost/benefit analysis. A comparison of cloud storage prices against the cost of buying new disk arrays is too simplistic. Consider all costs including internal payroll, array lifecycle costs. 
  • Online storage must be managed. Low price is not the best reason to switch to Storage-as-a-Service. Typically, hidden costs tend to reduce the perceived savings. Someone needs to manage online storage, ensure it is properly secured, available, and usable in the ways needed by the organization.

Top Storage-as-a-Service Providers 

Enterprise Storage Forum reviewed a variety of providers. Here are our top picks. 

Google Cloud Storage

Google Cloud logoGoogle is one of the giants of this field. It offers object storage for companies of all sizes for any amount of data that can be retrieved as often as you like. The company provides worldwide access and unlimited storage with no minimum object size at low latency with an annual durability rate of 99.999999999%. Google offers several tiers of cloud storage at different price points and performance levels. Once users decide which tier suits their needs, they are not stuck with it. Everything can be reconfigured as time goes on. 

Key Differentiators 

  • Standard Storage is intended for hot data accessed frequently or stored only briefly. It can be purchased in one or multiple locations for redundancy. It comes with a 99.5% service level agreement (SLA) guarantee for dual-region and multi-region storage. 
  • Nearline Storage is aimed at data that is expected to be stored and available for at least a month. It is cheaper than Standard Storage and is a good place to retain less frequently accessed data. Availability is a little lower than the higher tier, and there is a 30-day minimum storage duration. 
  • Coldline Storage is even lower cost and designed for data that is rarely going to be accessed. It has a 90-day minimum storage duration, and has higher costs for data access. 
  • Archive Storage is the lowest-cost tier and is good for data archiving, online backups and disaster recovery data.
  • Google offers Object Lifecycle Management to transfer data after so many days to a lower-cost storage class.
  • The Storage Transfer Service is used to move data from on-premises storage or from another cloud provider to the Google Cloud, as well as from one cloud location to another within the overall Google Cloud.  

Oracle Cloud Storage

Oracle logoOracle’s storage capabilities are part of its Infrastructure-as-a-Service (IaaS) product set. It offers block, file, and object storage. The Oracle Cloud Infrastructure Data Transfer Appliance allows users to securely move large volumes of data into Oracle Cloud quickly by means of a secure, encrypted appliance at no charge. Oracle object storage just added a new infrequent access tier. This tier costs less than the Standard tier, but objects in it can be immediately retrieved, unlike Archive storage tiers (a retrieval charge applies). The company also just introduced auto-tuning for object storage that enables users to configure a policy to automatically move little-accessed objects from Standard to the Infrequent Access tier.

Key Differentiators 

  • A data transfer service moves very large amounts of data into the cloud with a physical appliance.
  • Block Volumes use advanced, low-latency NVMe Solid State Devices (SSDs) and non-blocking network connectivity for every host, which provides high IOPS to Oracle compute services.
  • Oracle Cloud Infrastructure (OCI) Block Volumes offer strong storage performance SLA 
  • Volumes are up to 32 TB each and up to 32 can be attached to a running compute instance.
  • File Storage is a fully managed elastic POSIX and NFSv3-compliant file system that scales automatically to accommodate growth of up to 8 exabytes. 
  • File Storage eliminates the need to provision capacity in advance, so users pay only for the capacity they need. 
  • File Storage also offers snapshot and clone capabilities to simplify business continuity for enterprise applications. 
  • OCI File Storage employs 5-way replicated storage, located in different fault domains, to provide redundancy for data protection.
  • OCI Object Storage is best for building modern applications that require scale and flexibility as it can be used to consolidate multiple data sources for analytics, backup, or archive purposes.
  • OCI Object Storage provides API compatibility with the OpenStack Swift API and Amazon S3 through Oracle Cloud’s Amazon S3 Compatibility API.  
  • Additional performance options up to 300,000 IOPS per volume.
  • Cross-region replication with recovery point objectives (RPO) as low as 60 minutes and RTO that only takes a few minutes to complete.
