What Is a VDS (Virtual Dedicated Server)?
VDS is an acronym of Virtual Dedicated Server expression. The virtualization on physical infrastructure is presented and the resource allocation conditions express server service set by the provider. The word 'dedicated' in the question of what is VDS does not show that all physical servers belong to you or each package has the same isolation level.
How does VDS work?
Virtualization layer distributes the resources of physical server between virtual machines. Every virtual machine can work with its own operating system and applications. The CPU time depends on the infrastructure design and package conditions of memory and storage allocation.
The customer usually receives management access to the server. This access also gives updates, application installation and security responsibilities. It should also be noted that if the managed service is purchased, which works are undertaken. The presence of the server does not mean that the application is self-managed.
Difference between VDS and VPS
VPS and VDS terms can be used in different formats between providers. Only looking at the product name, CPU said, it should not be concluded that RAM is guaranteed or disk I/O is unlimited. Virtualization method and resource policy should be reviewed on the offer.
In addition to the number of vCPUs, CPU sharing, storage limit, traffic conditions and capacity increase are evaluated. The packages that bear the same numerical values can act differently on actual workload. The test through the application is more useful than label comparison.
What applications can VDS be suitable?
- Website and application hosting
- Database and business applications
- Development and testing environments
- Controlled remote access or integration services
- Welding needs regular measured small and medium-sized workloads
Package selection and operating responsibility
Set CPU, RAM and disk requirement with the measurements of the application. Add operating system license, backup, management, support and IP address bills to total cost. Vaccination fees should be checked with traffic or storage limits.
For example, disc lag in an application with intensive database access can be more decisive than a simple website. The acceptable response time should be defined before the test. Server failure, separate backup and return plan are prepared for incorrect update and data erasing. It is also verified whether the infrastructure snapshot is independent backup.
Frequently Asked Questions
Is VDS physical dedicated server?
No. VDS is a virtual server. A physical server is allocated to the customer in a physical dedicated service.
Is the CPU always said in VDS?
Depends on package conditions. The number of vCPU does not show only the physical nucleus per single.
Is there backup included in VDS?
Depends on the provider and package. Storage time, different location copy and restore conditions should also be asked.
