Pappaya Block Storage (PBS)

Block storage is a technology that stores data files on SANs or a cloud-based storage environment. It is a preferred mode of data storage for computing situations among developers. Block storage offers fast and reliable data transportation. 


Pappaya Block Storage is derived from an OpenStack project, namely Cinder. PBS offers the user the option to increase and decrease storage without costly physical upgrades to the server or storage. PBS provides persistent block storage to running instances.

Benefits of PBS

  • Performance is ideal for applications such as database servers due to low latency
  • Storage flexibility allows organizations to grow without any hindrance to performance
  • Allows effortless modification of files
  • OS can be quickly booted directly from PBS

Advantages of PBS

  • Simplified code management
  • No backend limitations
  • Easy integration
  • Single code for entire backend
  • Secure server

Typically, virtual machines boot up with the ephemeral volumes. This means, when we terminate the VM, the data within the VM is lost. If a user needs the data even though it is terminated, attach a persistent block device to those volumes so that the VM can write the information that needs to persist on that volume. 


When the VM gets terminated, the user is able to re-attach the block volume device to other instances. This provides the ability to continue using the existing information and get terminated instantly. This isn’t shared storage; it is block storage – meaning there is a one-one relationship between the volume and the instances. We have a separate project called Pappaya EFS for shared storage, which provides a shared file system for VMs.
