VPS vs Cloud Servers: What are the differences and similarities?

Do you know the differences between Cloud and VPS? With the emergence of virtualization resources as well as remote operations, there has been a considerable increase in companies, and even startups, that opt ​​for similar solutions to host their websites.

But what are the differences between VPS and Cloud Servers?

In a basic way, Cloud and VPS or Virtualization correspond to something that separates the hardware, the operating system and the application(s) running on that hardware.  The basic concept remains the same in both technology typologies, however, there are some differences that we will explore throughout the article.
What are VPS or VPS Hosting?
VPS Servers or VPS Hosting (Virtual Private Servers), also known as Private Cloud or in Portuguese as “Private Cloud” are based on servers created using virtualization mechanisms.  They are considered a form of accommodation situated between shared and dedicated accommodation.  They are extremely flexible and adjustable to customer needs.  It is a scalable service, allowing you to increase and decrease resources such as RAM, CPU, SSD according to your needs and without breaking the service.
Architecturally, VPS feature multiple individual dedicated slots within the same virtual machine.  Each slot can be assigned (different) dedicated resources.  However, it is important, in this context, to mention that VPS usually work in time-shared or with shared resources.  In practice, they work in a dedicated environment and in isolation from other clients, with the advantage that the cost is only a fraction of the price of a dedicated server.
One of the biggest disadvantages of VPS and that prevents them from reaching the next level is related to the vulnerability of failure or other type of disaster caused in a slot that will imply the unavailability of the websites/applications contained (break of service) until the problem is resolved. .
For example, there are situations such as cases of excessive and unexpected traffic on a random day or a DDoS (Distributed Denial of Service) attack, which can cause a breakdown of service on the entire machine and subsequent applications, as all resources belong to the same machine.  However, VPS have very interesting advantages, since this type of solution is situated between dedicated and shared hosting solutions.
Advantages of VPS

for having a Own operating system (OS) and dedicated resource allocation, VPS are not subject to instability issues caused by other clients or attacks targeting shared servers.  Although in a shared environment there is a resource limit per account, it is not always as effective as would be desirable.
In the environment dedicated and exclusive of a VPS, the client is better protected from harmful situations, whether originated by other customers or directed to them.  As each VPS uses its own operating system, this means that, for example, configuration errors or malware attacks are restricted to one OS;  other VPS operating on the same hardware configuration will not be affected by any security breaches or breaches.
VPS can also be adjusted over time to respond to customer needs.  Whether in increments or with the removal of resources (RAM, CPU) you will be sure that the service is dimensioned and always corresponds to your needs.
with respect to performancethis is higher in VPS, when compared to shared hosting, which translates into better access times to sites and platforms.


What are Cloud Servers or Cloud Hosting?
Cloud Servers, Cloud Hosting, Cloud Servers or cloud servers consist of an interesting interconnection of redundant equipment, capable of offering an inexhaustible infrastructure of resources, guaranteeing you high performance with controlled costs.  They are based on a distributed architecture composed of several high performance compute nodes (hypervisors) and central storage (SAN).
They are the ideal solution for those who need a distributed solution with high availability and who demand elasticity of adjustments in the resources (RAM and CPU) contracted.  Cloud Hosting is also the ideal solution to place ERP, CRM or other company platforms, as the environment is highly available and accessible 24x7x365.
Because they are elastic, Cloud servers are indicated for projects that require resource adjustments (upgrade/downgrade): in a Cloud Server, although reboots are necessary to upgrade/downgrade RAM memory, disk space or CPU, this can be configured to scale when it is close to reaching its limit.
Advantages of Cloud Servers

They have high performance with controlled costs and scale according to the needs of the Clients;
They have the ability to relocate and prevent failures, that is, in the event of a service break, the system automatically moves to the reserve
Live Migrate (non-breaking and working migration) from the Server to another Cloud zone, even in cases of unexpected failures.
Growth is assured at:

Horizontal – (with new servers) – can theoretically scale to infinity.  Just add new servers and put them into production with the ones that already exist, however, the platform must be prepared in advance to accommodate growth.
Vertical – (feature adjustment)




Cloud Servers vs VPS
There are some differences between both types of servers, however, there is a general tendency of misunderstanding and sometimes misunderstandings about the existing technological differences.
This is mainly due to the fact that there is often a lack of knowledge about the differentiating factors between both technologies in the hosting universe.  Can see here differences between VPS and Cloud Servers.
