Since cloud computing popularity is growing, users have much more in a misunderstanding in the terminology. Often providers produce misunderstanding by calling virtual dedicated servers as a cloud. We introduce brief info about these odds that can help you remember the difference and won’t be confused anymore.
A cloud solution is an IT infrastructure built at the provider’s equipment and deployed at the remote data center. You configure the components of your cloud project by yourself by choosing all necessary computing capacities. Then you can deploy in a cloud infrastructure ERP system, email server, remote desktops, data storage, you can install the apps and software you need, and so on.
Cloud infrastructure types:
- Private cloud
- Public cloud
- Hybrid cloud
A private cloud is a single-tenant custom-tailored cloud solution built for the only customer (enterprise, usually) with a specific configuration of computing resources and a high level of IT security. A private cloud gives customers the highest levels of reliability, redundancy, stability, and availability. This kind of infrastructure is quite expensive, so it is chosen by large corporations as a rule.
A public cloud is the most common available cloud service model. This type of infrastructure combines physical servers, network equipment, and other devices into an entire capacities pool. And the customer gets remote access to capacities that are dynamically redistributed between users depending on their needs. Any customer does not depend on any particular equipment, and upon rebooting or failure of any equipment, its functions intercept the equivalent capacities from the resource pool due to redundant architecture of the public cloud. You can learn more about this service at the website of the cloud provider SIM-Networks.
Note that users in the public cloud are separated from each other by hardware- and software-based security tools, so the data is safe and completely confidential.
A hybrid cloud is the most extensive solution for corporations. Within the most general case of hybrid cloud infrastructure, the critical part of the resources is located in a private cloud or on-premises, and the scalable part of corporate IT infrastructure, which is required at peak times, is migrated to a public cloud.
Note that VDS, a virtual dedicated server, and VPS, a virtual private server, are the same thing. A virtual server creates based on a dedicated physical server using specific software, a hypervisor. This software distributes resources between users, creating several independent virtual servers that use the capacities of one server. Thus, VDS looks more like a hosting than a cloud, although people, and even hosting providers sometimes call it cloud.
A dedicated server is the solid enterprise-class bare metal server that is located remotely at a hosting provider data center. You can operate with the dedicated server as usual like you do with your on-premises, e.g., install a preferable operating system, apps you need, you even can install there a hypervisor, and create some virtual dedicated servers, if you’d like. Bare metal server rental https://www.sim-networks.com/en/dedicated is very demanded service amongst businesses of any size to deploy high-loaded apps and systems, or as a corporate server.
So what can we say as a conclusion
VDS is the cheapest and easiest solution. It has small resources, and its matter is a dedicated part of computing resources deployed at a physical server.
A dedicated (or a bare-metal) server is your own remote hardware computing resource that you can manage by yourself, and you can install anything you need.
A cloud is a specific configuration of computing resources that can scale and adapt to your requirements.
I hope, our article has helped you understand the terminology of cloud computing a tad better.
