Virtual Machine (VM)
Virtual machines simulate full computer environments – with their own operating system, kernel, and resources.
For developers: a stable, isolated platform.
For operators: flexible multi-tenant environments.
For decision-makers: proven technology for security, legacy compatibility, and compliance.
And for us: a key tool – especially for hybrid and traditional infrastructures.
What is a VM?
A VM is a fully virtualized computer running on a hypervisor (e.g., KVM, VMware, Hyper-V).
It includes:
- its own operating system
- a dedicated kernel and driver layer
- isolated resources (CPU, RAM, storage)
VMs behave like physical servers – but are more flexible and efficient to operate.
Benefits of VMs
- Strong isolation – ideal for security and multi-tenancy
- Compatibility – for legacy apps and specialized OS setups
- Independence – from other systems and the host
- Stability – proven in countless production environments
Common use cases
- Hosting multiple customers in isolated systems
- Running monolithic or legacy applications
- Projects with high security or compliance requirements
- Systems with specific hardware or OS needs
What VMs are not
- Fast-starting, lightweight environments like containers
- Ideal for highly dynamic, short-lived workloads
- Required for every use case – modern apps are often ready for containerization
VMs are robust and proven – but not always the most flexible choice.
How we work with VMs at RiKuWe
- We run secure, high-availability VM infrastructures
- All systems are regularly patched, monitored, and backed up
- Snapshots, replication, and VM backups ensure reliability
- On request, we combine VMs with container technology
For us, VMs aren’t legacy – they’re part of a professional operating strategy.
Frequently Asked Questions
What is a virtual machine?
A virtual machine (VM) is a fully isolated computer system with its own operating system, running on a host via a hypervisor.
What’s the difference between a VM and a container?
A VM virtualizes hardware – including its own kernel and OS. A container virtualizes only the application layer and shares the host’s kernel. VMs are heavier, but more isolated.
When should I use a VM instead of containers?
When you need strong isolation, legacy compatibility, or specific operating systems – for example, in customer hosting or security-sensitive applications.
Are VMs outdated?
No. VMs are stable, battle-tested, and still essential in many scenarios. They complement container setups where security and compatibility matter more than agility.
How does RiKuWe operate virtual machines?
We manage VMs with regular patches, backups, monitoring – and optionally with snapshots and replication. Hybrid setups with containers are also possible.
