I'm looking for the right offer to host a web application. I still hesitate between the different offers, and I can not understand what the difference is between Cloud Server and VPS. which is best, Cloud Server or VPS ?
As the new Cloud concept is gaining ground, more and more people and companies are wondering what the difference is between a cloud server and a VPS server. Although at first glance both technologies may seem similar, at operational level and results the difference between the two is significant. What is the difference between a cloud server and a VPS server? Here's what we explain.
The VPS server
It is based on a single physical machine whose resources are shared among multiple users. This is the technology that precedes the Cloud and although at the time it was a cheaper alternative to the use of a dedicated server, it shares with the latter some important problems that can adversely affect its operation. For example, your susceptibility to hardware failures.
The Cloud Server
It is a highly scalable virtual server that abstracts the physical server. This is supported by a redundant infrastructure, specially prepared for this purpose, in which a set of physical servers are distributed execution of the different virtual instances. In recent years, cloud computing is gaining more and more relevance due to the advantages they offer, especially at the enterprise level, its greater flexibility and its tolerance to hardware failures.
The Cloud Server is fault tolerant. In case a physical server fails, the system will simply search for the next node to connect to and maintain any running service without risk of interruption times. For a business use this is a key advantage.
The Cloud Server offers greater scalability and flexibility by allowing immediate modification of the allocated resources. We can increase or decrease the number of vCores, Ram and disk capacity without having to change the server or the configuration of our services. In a physical server this is not possible since we will never be able to overcome the own resources of the machine.
The Cloud Server guarantees the actual availability of the contracted resources. In the case of VPS, the performance of the server can vary depending on the intensity of use of the other users with whom the machine is shared. Therefore, it may be the case to pay for a VPS service whose services we do not get to enjoy 100%. In a VPS server it is impossible to guarantee the use of resources, in a Cloud server itself.
Cloud Hosting and VPS Hosting are run on Virtualization Technology. For E-Commerce website i recommend to you go for Cloud Hosting. Because is modernized from VPS hosting. Cloud offers benefits, it is flexible, reliable, affordable and scalable on demand where you increase and decrease your resources capacity with few clicks.VPS also scalable but it’s take time to add resources but it slow down server when traffic goes to peak.Another disadvantage of VPS, if server goes fail then your work would stop. But In cloud hosting if any components or server fails then your website automatically shift on another server, that makes it more reliable.
Cloud server is far superior to a VPS when it comes to server resources scalability (on demand) and fault tolerance. The technology behind cloud server is gaining much ground and you would be better off with a cloud server.
Though if your needs are on the low side, a robust VPS from a good hosting provider is more than enough to take care of your hosting needs.
The basic difference is that VPS is a bunch of virtual servers that are hosted on one physical machine whereas in the Cloud, a large network of machines are integrated to create a virtual space for server hosting called the "Cloud".
Because of this basic difference other differences between the two types of hosting have come to be. For instance, Cloud servers are much more scalable than VPS since VPS is similar to a dedicated server. Cloud servers also have minimum room for downtime. As I said earlier this is an integration of multiple physical machines. Therefore if one machine goes offline the virtual servers can still be migrated to one that is up and running. So cloud hosting is also much more redundant.
Cloud hosting costs more than VPS because it requires complicated networking and high uptime. For the same reason the cost of a cloud server cannot be predetermined. The cost of a VPS is lower than a cloud server and you will know what payments to meet each month.
A virtual private server is a single physical server, split up between a limited number of users. It is a similar hosting set-up to a shared server, where many user accounts are located on the same server. The main difference between these two server setups is that VPS accounts have fewer users per box, and the users get more control over their section of the server. Virtualization software divides the users from each other, although you’re not entirely isolated from being affected by other people on your server.
A private cloud uses distributed resources across multiple physical servers. The redundancy allows for a seamless transition to the other servers in a network in the event of a hardware failure or other issue. It’s similar to a RAID 5 hard drive setup. You see the resource as one server, but multiple systems are behind it.
A major difference between a VPS and a private cloud is the location of the hardware. A virtual private server is generally hosted at an off-site, third-party web hosting provider. A private cloud is situated on site or at a data center you own. There are exceptions to this rule, however, as some cloud providers are offering hosted private clouds for users. These clouds use hardware that is solely for the use of that particular cloud and is not shared with other users.
Cloud control panels are built with quick provisioning and deployment in mind. The process to get a new virtual server, database or other resource up and running typically takes only a few clicks through the administrative panel. A VPS requires you to upgrade your service manually, send in a support ticket to the provider, or call to get tech support to provide you with the resource needed, making a private cloud more convenient in this regard.
A private cloud is rather expensive in terms of hardware, as you have to shoulder the cost of the hardware, installation, set-up, and maintenance. This is lowered somewhat if you go with a hosted private cloud, but you don’t have the same level of control on a hosted cloud as you do with your own, on-site option. A virtual private server is vastly less expensive and even cheaper than dedicated server hosting. If cost is an issue, the VPS wins out every time.
Information security is one of the most important means of VPS. This hosting has several advantages over cloud hosting. In particular, all your data is stored on one server, and not distributed across several. Root access provides extensive security configuration options. But if the site undergoes a DDoS attack, it will affect the remaining VPS on the same host.
With cloud hosting, securing security can be more difficult as the data and resources are distributed across different servers and sites. Most cloud hosting providers provide root access to clients, but you need to understand that data can be physically stored in several places. But in a cloud environment, one client is completely isolated from the files of another - from this point of view, the environment is more secure.
The biggest difference between the two server environments is scale. If you’re looking to launch as quickly as possible and don’t care about scale, then a VPS server can be a great starting point. However, if you demand a flexible hosting setup and a high level of site performance and storage then it’s worth checking out a cloud hosting environment.
VPS hosting is normally less efficient since it allocates us a specific amount of computing resources to each client. Hence, at some point, if requirement increases then the system would not able to handle the additional flow while in Cloud hosting tackles the increase in a different way because under the environment of cloud, the website is hosted on a pool unified computing system.
VPS is not much Scalable as it can’t able to add more server power while in Cloud hosting it is more scalable as it can add more server power at a moment
The key difference is that instead of having a single server that's dedicated to your site (as is the case with VPS), the resources are spread out amongst a bunch of different physical machines. With cloud hosting, you have a network of potentially unlimited virtual machines.
Cloud hosting and virtual private server (VPS) hosting are two options to consider when determining how to host a website, but what makes them different? While cloud hosting provides an unlimited number of interconnected computers/servers that share access to the same data system, VPS hosting provides space for each user on a single dedicated server or group of servers.
Performance is another key component of how cloud hosting differs from VPS hosting. With cloud hosting, performance can constantly be maximized depending on usage. This is due to having multiple servers available at all times to address the need for more speed. Cloud hosting is also helpful when one server fails; the file and the functionality can be shifted automatically without downtime or significant delay.
In VPS hosting, performance is guaranteed with respect to having many machines that are running concurrently. It is important to consider that VPS hosting servers are physical machines and failure of hosting machines will result in outages for the entire server. However, VPS hosting can often be moved to cloud hosting in such an event and until repairs are completed.
Also scalability is something that differs between the two types of hosting. In the case of cloud hosting, the sky is literally the limit. When more or less resources are needed, the cloud host can increase or decrease accordingly. In the case of VPS hosting, the level of service tends to be limited due to the physical size of the network equipment provided.
