In the industrial segment, operational technology (OT) and embedded systems are at an inflection point as they move from specialized, single-purpose hardware to obtain the business and technology advantages of hosting multiple workloads/applications on general-purpose servers. Major industrial equipment companies are beginning to build on the approaches to transformation that have proven themselves in the information technology (IT) realm, bringing those same architectures to OT systems. Virtualization and containerization technologies have been successful for IT, and now these technologies are taking on the OT challenge.

THIS WHITE PAPER EXPLORES HOW

  • Hypervisor-based virtualization can enable an application or workload to run in its own virtual machine (VM) on a single server or on a system board running multiple VMs using different operating systems.
  • A VM running a critical application or workload can be safely partitioned away from interference with other VMs.
  • Container-based virtualization can provide a lightweight alternative to VMs, with multiple containers able to share a single OS instance.
  • Using a combined hypervisor-based VM-and-container solution can provide the best of both technologies.
