What are the differences and similarities?

Do you know the difference between cloud and VPS? With the advent of virtualized resources and remote operations, there has been considerable growth in companies and even startups opting for similar solutions to host their websites.

But what is the difference between a VPS and a cloud server?

VPS vs Cloud Server: What are the Differences and Similarities?

Fundamentally, cloud and VPS or virtualization correspond to what separates the hardware, the operating system, and the applications running on that hardware. The basic concepts of both technology types remain the same, however, we will explore some differences throughout the article.

What is VPS or VPS hosting?

A VPS server or VPS hosting (Virtual Private Server), also known as a private cloud or "private cloud" in Portuguese, is based on servers created using virtualization mechanisms. They are considered a form of accommodation between shared accommodation and dedicated accommodation. They are very flexible and can be adjusted according to customer needs. It is a scalable service that allows you to increase and decrease resources such as RAM, CPU, SSD, etc. as needed without interrupting service.

Architecturally, a VPS has multiple separate dedicated slots within the same virtual machine. A (different) dedicated resource can be allocated for each time slot. However, in this case, it is important to mention that VPS usually work in a time-shared or shared resource manner. In effect, they work in a dedicated environment, isolated from other clients, with the advantage of costing a fraction of the price of a dedicated server.

One of the biggest downsides of VPS is preventing them from reaching the next level, which has to do with vulnerability to failures or other types of disasters caused in the slot, which will mean the contained website/application is unavailable (service interruption) until a problem solved. .

For example, a random day of heavy traffic and unexpected situations or a DDoS (distributed denial of service) attack, etc., can crash the service of the entire machine and subsequent applications because all resources belong to the same machine. However, VPS has very interesting advantages as this type of solution sits between dedicated and shared hosting solutions.

Advantages of VPS

  • because there is a own operating system (OS) and dedicated resource allocation, VPS is immune to instability issues caused by other clients or attacks against shared servers. Although there is a resource limit per account in a shared environment, it doesn't always work as expected.
  • in the environment Focus and exclusive A VPS, client Better protection from harmful situations, whether initiated by or directed to other customers. Since each VPS uses its own operating system, this means that, for example, a misconfiguration or malware attack is limited to one operating system; other VPSs running on the same hardware configuration will not be affected by any security holes or vulnerabilities.
  • VPS can also Adjust over time Respond to customer needs. Whether incrementing or removing resources (RAM, CPU), you will ensure that the service is tuned and always meets your needs.
  • about Performancewhich is higher in VPS compared to shared hosting, which means less time to visit the site and platform.

What is cloud server or cloud hosting?

Cloud servers, cloud hosting, cloud servers or cloud servers consist of an interesting interconnection of redundant devices capable of providing an inexhaustible resource infrastructure that guarantees your high performance at a manageable cost. They are based on a distributed architecture consisting of multiple high-performance computing nodes (hypervisors) and central storage (SAN).

They are ideal for those who need a distributed solution with high availability and for those who need elastic adjustment of contract resources (RAM and CPU). Cloud hosting is also an ideal solution for placing ERP, CRM or other business platforms as the environment is highly available and accessible 24x7x365.

Because they are elastic, cloud servers are suitable for projects that require resource tuning (upgrade/downgrade): in a cloud server, although upgrading/downgrading RAM memory, disk space or CPU requires a restart, it can be configured to limit.

Advantages of cloud servers

  • They have high performance Control costs And expand according to customer needs;
  • They have the ability to relocate and prevent failure, i.e. in the event of a service interruption, the system automatically moves to standby
  • Live migration (Non-disruptive and work migration) from server to another cloud region, even in the event of unexpected failure.
  • Growth is guaranteed:
    • horizontal - (with new server) - can theoretically scale to infinity. Just add new servers and put them into production alongside those that already exist, however, the platform must be prepared ahead of time to accommodate growth.
    • vertical – (function adjustment)

Cloud server and VPS

There are some differences between the two types of servers, however, there is a general tendency for misunderstandings and sometimes misunderstandings about existing technical differences.

This is mainly due to the general lack of knowledge about the factors that differentiate the two technologies in the hosting world. Here you can see the difference between VPS and cloud server.
