Understanding Object Storage and Block Storage Use Cases

Cloud Computing, like any computing, is a combination of CPU, memory, networking, and storage. Infrastructure as a Service (IaaS) platforms allow you to store your data in either Block Storage or Object Storage formats.

Understanding the differences between these two formats – and how they can sometimes be used together – can be a critical part of designing an overall storage profile. And the relatively low costs of cloud storage, along with its durability and high availability, can make it attractive even for local infrastructure projects.

What is Block Storage?

Block storage devices provide fixed-sized raw storage capacity. Each storage volume can be treated as an independent disk drive and controlled by an external server operating system. This block device can be mounted by the guest operating system as if it were a physical disk. The most common examples of Block Storage are SAN, iSCSI, and local disks.

Block storage is the most commonly used storage type for most applications. It can be either locally or network-attached and are typically formatted with a file system like FAT32, NTFS, EXT3, and EXT4.

Use cases

  • Ideal for databases, since a DB requires consistent I/O performance and low-latency connectivity.
  • Use block storage for RAID Volumes, where you combine multiple disks organized through stripping or mirroring.
  • Any application which requires service side processing, like Java, PHP, and .Net will require block storage.
  • Running mission-critical applications like Oracle, SAP, Microsoft Exchange, and Microsoft SharePoint.

Block storage options in the cloud

  1. AWS Elastic Block Storage (EBS): Amazon EBS provides raw storage – just like a hard disk – which you can attach to your Elastic Cloud Compute (EC2) instances. Once attached, you create a file system and get immediate access to your storage. You can create EBS General Purpose (SSD) and Provisioned IOPS (SSD) volumes up to 16 TB in size, and slower, legacy magnetic volumes.
  2. Rackspace Cloud Block Storage: Rackspace provides raw storage devices capable of delivering super fast 10GbE internal connections.
  3. Azure Premium Storage: Premium Storage delivers high-performance, low-latency disk support for I/O intensive workloads running on Azure Virtual Machines. Volumes allow up to 32 TB of storage.
  4. Google Persistent Disks: Compute Engine Persistent Disks provide network-attached block storage, much like a high speed and highly reliable SAN, for Compute Engine instances. You can remove a disk from one server and attach it to another server, or attach one volume to multiple nodes in read-only mode. Two types of block storage are available: Standard Persistent Disk and Solid-State Persistent Disks.

What is Object Storage

Block storage volumes can only be accessed when they’re attached to an operating system. But data kept on object storage devices, which consist of the object data and metadata, can be accessed directly through APIs or http/https. You can store any kind of data, photos, videos, and log files. The object store guarantees that the data will not be lost. Object storage data can be replicated across different data centers and offer simple web services interfaces for access.

A simple use case would see application developers who deal with large amounts of user-generated media, using object storage to store unlimited media files. As data stores scale to hundreds of terabytes and then into the petabyte range and beyond, object storage becomes even more attractive.

Use Cases

  • Storage of unstructured data like music, image, and video files.
  • Storage for backup files, database dumps, and log files.
  • Large data sets. Whether you’re storing pharmaceutical or financial data, or multimedia files such as photos and videos, storage can be used as your big data object store.
  • Archive files in place of local tape drives. Media assets such as video footage can be stored in object storage and archived to AWS glacier.

Object storage options in the Cloud

  1. Amazon S3Amazon S3 stores data as objects within resources called “buckets.” AWS S3 offers features like 99.999999999% durability, cross-region replication, event notifications, versioning, encryption, and flexible storage options (redundant and standard).
  2. Rackspace Cloud Files: Cloud Files provides online object storage for files and media. Cloud Files writes each file to three storage disks on separate nodes that have dual power supplies. All traffic between your application and Cloud Files uses SSL to establish a secure, encrypted channel. You can host static websites (for example: blogs, brochure sites, small company sites) entirely from Cloud Files with a global CDN.
  3. Azure Blob Storage: For users with large amounts of unstructured data to store in the cloud, Blob storage offers a cost-effective and scalable solution. Every blob is organized into a container with up to a 500 TB storage account capacity limit.
  4. Google cloud storage: Cloud Storage allows you to store data in Google’s cloud. Google Cloud Storage supports individual objects that are terabytes in size. It also supports a large number of buckets per account. Google Cloud Storage provides strong read-after-write consistency for all upload and delete operations. Two types of storage class are available: Standard Storage class and Storage Near line class (with Near Line being MUCH cheaper).

Conclusion

Object storage and Block storage both have unique advantages and limitations. Understanding the use cases and costs associated with each medium will help you get the best possible mileage out of your application storage profile.

My professional IT career began nine years back when I was just out of my college. I worked with a great team as an infrastructure management engineer, managing hundreds of enterprise application servers. I found my passion when I got the opportunity to work with Cloud technologies: I'm addicted to AWS Cloud Services, DevOps engineering, and all the cloud tools and technologies that make engineers' lives easier. Currently, I am working as a Solution Architect in SixNines IT. We are an experienced team of engineers that have helped hundreds of customers move to the cloud responsibly. I have achieved 5 AWS certifications, happily helping fellow engineers across the globe through my blogs and answering questions in various forums.
