Using OpenStack for Private Cloud Infrastructures in Telco
As telecommunications organizations continue to explore the efficiencies and cost-savings of telco cloud, few infrastructure-as-a-service (IaaS) platforms have seen as much success as OpenStack.
In this blog, we explore the benefits of managing private cloud infrastructures with OpenStack, while exploring some of the comparisons between the different OpenStack deployment models.
What is OpenStack?
is the most widely deployed open source cloud software in the world. It provides the essential building blocks for managing virtual clouds (both public and private), and is capable of delivering the cloud infrastructure for virtual machines, bare metal, and containers.
In other words, OpenStack virtualizes network functions into clouds and offers a flexible solution for managing those clouds through APIs /web-based dashboards. It consists of numerous interconnected components, each of which works together to manage the full lifecycle of cloud management.
What are the key components of OpenStack?
A single OpenStack deployment can contain a wide range of components / APIs for accessing infrastructure resources. Weve listed each component below, and marked the most important ones with an asterisk.*
Compute
- : Compute Service. Provides access to computing resources.
- : Containers Service.
Hardware Lifecycle
- : Bare Metal Provisioning Service.
- : Lifecycle management of accelerators.
Storage
- : Object store. Stores / retrieves large amounts of data.
- : Block Storage. Provides block-level storage for VMs.
- : Shared filesystems.
Networking
- : Networking. Provides networking-as-a-service (NaaS).
- : Load balancer.
- : DNS service.
Shared Services
- : Identity service. Provides authentication and authorization across all components.
- : Placement service. Tracks the usage of resources.
- : Image service. Provides a repository for VM images.
- : Key management.
Orchestration
- : Orchestration.
- : Workflow service.
- : Messaging Service.
- : Resource reservation service.
- : Alarming Service.
Workload Provisioning
- : Container Orchestration Engine Provisioning.
- : Database as a Service.
Application Lifecycle
- : Backup and Restore.
- : Instances High Availability Service.
Web frontends
- : Dashboard. Provides an interface for managing all resources.
- : Next generation dashboard.
Should telco organizations use OpenStack?
OpenStack claims that implementing Network Functions Virtualization (NFV) strategies believe OpenStack is essential to their success. In terms of the most common use cases, say they use OpenStack to manage private clouds, while 35% are using it as the basis for NFV.
For telcos, there are five major benefits to choosing OpenStack:
- Network agility: OpenStack offers higher levels of flexibility, scalability and resiliency compared to most enterprise solutions.
- Cost savings: Its cheaper to install and manage infrastructure through OpenStack.
- Track record: OpenStack has been implemented by some of the worlds leading telcos.
- Open standards: Adhering to ETSI and OPNFV means OpenStack is more collaborative in nature.
- Vendor support: Many industry-leading solutions are based on OpenStack and come with strong technical support.
Which telco organizations are using OpenStack?
OpenStack is a popular tool within the telco landscape. are connected to virtualized network services, many of which are based on OpenStack, while covers around 6,000 bare metal servers and VMs.
Elsewhere, to over 75% of the UK population in April 2025. Further afield, has reduced costs and complexity by embracing OpenStack as part of a unified cloud environment.

Is OpenStack a public or private cloud?
While OpenStack can be used to build private clouds, its also common within public clouds. According to OpenStack, there are throughout the world.
One of the key advantages of OpenStack is its flexibility, which allows organizations to choose the type of cloud deployment that best suits their requirements. There are five main deployment methods to be aware of
On-premises
This deployment model involves installing and managing the OpenStack platform on the hardware of an individual user.
- Advantages: Increased control, customization and security.
- Disadvantages: Slow deployment, lack of technical expertise, high operational costs, complex to manage.
Public cloud based on OpenStack
In this model, an OpenStack-based public cloud solution provides the underlying infrastructure, giving users access to resources through APIs / a web interface.
- Advantages: Reduced overheads, limited expertise required.
- Disadvantages: Less control over data, minimal customization.
OpenStack-based private cloud
This occurs when an OpenStack platform is managed by a third-party vendor, but used by a single organization (who maintain control over their data and applications).
- Advantages: Faster to deploy, reduces operational complexity.
- Disadvantages: May not be compatible with existing infrastructure, reduced control over data, potential vendor lock-in.
OpenStack-as-a-Service
This is when a cloud service provider offers a private OpenStack cloud environment to customers as a fully managed solution.
- Advantages: Massive reduction in operational complexity, avoids vendor lock-in, rapid deployment.
- Disadvantages: Requires consistent and secure HTTPS access between customer and vendor.
OpenStack with Kubernetes
Thanks to the complementary nature of OpenStack and Kubernetes, OpenStack services can also be deployed as containers in a Kubernetes cluster.
- Advantages: Provides the added scalability, flexibility and simplicity of Kubernetes.
- Disadvantages: Requires additional technical knowledge to perform.
Its also worth noting that OpenStack recommends a number of tools for managing the lifecycle of OpenStack deployments:
- : Deploys OpenStack in containers using Helm.
- : Deploys OpenStack in containers using Ansible.
- : Deployment of containerised OpenStack to bare metal.
- : Ansible playbooks to deploy OpenStack.
- : Deploys OpenStack in containers using Charms and Juju.
- : Ansible playbooks using ironic.
Public cloud alternatives to OpenStack
If you dont need a private solution, there are numerous public cloud alternatives to OpenStack which you can consider although the potential benefits of each platform will depend on your specific requirements.
For large-scale deployments, , and offer mature platforms with a wider range of features to explore. In contrast, the developer-friendly environments of , and might be better suited to smaller / simpler deployments. And, if an open-source solution is non-negotiable, then or are both potential alternatives to OpenStack.
That said, we believe that a private OpenStack cloud is the best option for securing the unique combination of flexibility, scalability, and cost-efficiency that telcos require to manage their network infrastructure in the modern world.
