Category Archives: VMware Integrated OpenStack (VIO)


VMware Integrated OpenStack (VIO) is an OpenStack distribution that is built and tested by VMware. VIO is compliant with the OpenStack Foundation guidelines for an OpenStack distribution and is API-compatible for all OpenStack services running on enterprise level virtual infrastructure.VMware ensures platform stability by rigorous testing and ensuring interoperability. VIO leverages vSphere, NSX, and storage functionality as core of infrastructure. VMware places priority on packing OpenStack core projects in the most stable manner through relentless testing (functional and interoperability).

VMware Integrated OpenStack provides the following key features:
• Fastest deployment with simple installation using an OVA file
• Simplified operations through API and web interface
• Distributed Resource Scheduler (DRS) and Storage DRS for workload    rebalancing and datastore load balancing
• vSphere high availability (HA) to protect and automatically restart workloads
• In-house expertise and skillset with existing vSphere technology
• Runs on the proven VMware software-defined data center
• Production-ready container management that is natively integrated by using VMware capabilities.

• Advanced networking functionality through NSX 

• Integration with vRealize Operations Manager and vRealize Log Insight for greater performance and capacity management, Alerting and troubleshooting.  
• Trusted and single vendor for infrastructure and OpenStack
• Compliant with the OpenStack Foundation’s 2019.11 interoperability guideline

OpenStack Model

The OpenStack model is comprised of core projects and supplement projects. In addition to the core OpenStack projects, customer can choose supplement projects for additional services and functionality based on their requirements.

VMware Integrated OpenStack Components

VMware Integrated OpenStack (VIO) is made by two main building blocks, first the VIO Manager and second OpenStack components. VIO is packaged as an OVA file that contains the VIO Manager server and an Ubuntu Linux virtual machine to be used as the template for the different OpenStack components.

VMware Integrated OpenStack is designed to run over vSphere and NSX-T Data Center, leveraging existing virtualization functionality to provide security, stability, performance, and reliability.

Plug-in drivers are available in Nova for interaction with vCenter Server  and in Neutron to interact with NSX-T Data Center (or vSphere Distributed Switch). Glance and Cinder interact with storage through the vCenter Server system and the OpenStack plug-in driver.

VMware Integrated OpenStack and the VMware SDDC Integration 

VMware Integrated OpenStack (VIO) provides full-stack integration with VMware Software-Defined Data Center (SDDC), which provides customer to have one-stop-shop enterprise grade OpenStack solutions.

Why VMware Integrated OpenStack (VIO) – Part 1

Time to move out from comfort zone, explore and deep dive into OpenStack, Specially VMware Integrated OpenStack (VIO), vSphere with Kubernetes, VMware Tanzu Kubernetes Grid (TKG), and VMware Tanzu Kubernetes Grid Integrated (TKGI) (formerly known as VMware Enterprise PKS).

Let’s Start with VMware Integrated OpenStack (VIO)?

VMware Integrated OpenStack (VIO) is a VMware supported enterprise grade OpenStack distribution that makes it easy to run OpenStack cloud on top of VMware virtualization technologies. With VIO, customers can rapidly build production-grade private and public OpenStack clouds on top of VMware technologies, leveraging their existing VMware investment and expertise.

VMware Integrated OpenStack is ideal for many different use cases, including building a IaaS platform, providing standard, OpenStack API access to developers, leveraging edge computing and deploying NFV services on OpenStack.

VMware Integrated OpenStack (VIO) can be deployed and run on your existing vSphere, NSX-T, and vSAN and simplify operations and offering better performance and stability.

VMware Integrated OpenStack (VIO) Architecture

The VMware Integrated OpenStack (VIO) connects vSphere resources to the OpenStack Compute, Networking, Block Storage, Image Service, Identity Service, and Orchestration components.

VMware Integrated OpenStack is design and implemented as separate management and compute clusters. The management cluster contains OpenStack components and compute cluster runs tenant or application workloads.

VMware Integrated OpenStack (VIO) core components are :-

Nova (compute) – Compute clusters in vSphere are used as Nova compute nodes. Nova Provides a way to provision compute instances (aka virtual servers) in these clusters.

Neutron (networking) – Neutron allows you to create and attach network interface devices managed by OpenStack. Neutron provides networking functions by communicating with the NSX Manager (for
NSX-T Data Center deployment) or with vCenter Server (for VDS-only deployments).

Cinder (block storage) – Cinder designed to create and manage a service that provides persistent data storage to applications. Cinder executes block volume operations through the VMDK driver, causing the desired
volumes to be created in vSphere.

Glance (image service) – Glance enables users to discover, register, and retrieve virtual machine images through the Image service in a variety of locations, from simple file systems to object-storage systems  like OpenStack Object Storage. Glance images are stored and cached in a dedicated image service datastore when the virtual machines that use them are booted.

Keystone (identity management) – Authentication and authorization in OpenStack are managed by Keystone.

Heat (orchestration) – Heat provides orchestration service to orchestrate composite cloud applications through an OpenStack API call.

Ceilometer (telemetry) – Telemetry collect data on the utilization of the physical and virtual resources comprising deployed clouds, persist these data for subsequent retrieval and analysis, and trigger actions when defined criteria are met.

VMware also provides simplified OpenStack operations with vRealize Operations Manager (vROps) integrations for performance monitoring, capacity planning and troubleshooting. And vRealize Log Insight (vRLI) for diagnostics across OpenStack service logs.
