What are the dif­fer­ences between VPS and dedicated servers?

VPSs and dedicated servers both offer dedicated resources with in­de­pen­dent servers for in­di­vid­ual re­quire­ments. VPS involves sharing the host server’s power with others, while dedicated hosting offers a full-fledged physical server with computing power ex­clu­sive­ly reserved for you.

Having a server of your own offers many ad­van­tages for private in­di­vid­u­als. For companies with large online projects, it’s prac­ti­cal­ly non-ne­go­tiable. Both shared hosting and dedicated hosting are usually suf­fi­cient for bloggers and in­di­vid­u­als who run smaller websites or manage small online stores. The re­quire­ments are different for busy online stores, gaming servers with a lot of traffic, and companies or in­di­vid­u­als with an extensive online presence. In addition to dedicated servers, there are also VPS and cloud hosting solutions available. Let’s take a closer look at the dif­fer­ences between VPS and dedicated servers.

VPS vs. Dedicated servers

Both hosting models provide an in­de­pen­dent server en­vi­ron­ment with a lot of flex­i­bil­i­ty. They also do not require a costly data center or high-main­te­nance servers as is the case with an on-premises model. Unlike cloud hosting, however, VPS and dedicated hosting require server ad­min­is­tra­tion knowledge. You can opt for a managed hosting plan though, which takes care of the server settings for you.

Below we’ve provided a list of the key dif­fer­ences and features of VPS and dedicated servers:

Dif­fer­ence 1: Pro­vi­sion­ing

In both hosting models, resources are provided by external companies. However, one of the biggest dif­fer­ences is how they are provided.

In the case of a virtual private server (VPS), or a VDS (virtual dedicated server), a provider uses vir­tu­al­iza­tion tech­nol­o­gy to segment a physical server into in­de­pen­dent virtual par­ti­tions. Although customers share a physical host server, the resulting virtual servers operate as closed systems with their own IP and in­di­vid­ual con­fig­u­ra­tion. A hy­per­vi­sor is used to manage and dis­trib­ute the server’s ca­pac­i­ties. The dis­ad­van­tage of a VPS is its limited per­for­mance and the fact that you have to share resources with others. While VPS is based on hardware ab­strac­tion, a dedicated server is a full-fledged, physical server. You do not have to share physical memory, per­for­mance or other hardware com­po­nents with other users. Even if you have a large project with high workloads, you’ll have access to the server’s full capacity.

Dif­fer­ence 2: Scaling & per­for­mance

Scal­a­bil­i­ty is one of the most important factors to consider when choosing a hosting plan. This is es­pe­cial­ly important if the amount of resources required is uncertain. Although VPS and dedicated servers cannot compete with the scal­a­bil­i­ty offered by cloud hosting, VPS does offer flex­i­bil­i­ty. Depending on the dedicated server plan you choose, you’ll be able to access full computing power right from the start. The strong per­for­mance and computing power offered by dedicated servers is suf­fi­cient for large and complex tasks. However, if ad­di­tion­al resources are needed, ad­di­tion­al dedicated servers, which can be expensive, are required.

VPS hosting therefore comes out on top for companies who need scal­a­bil­i­ty that is flexible and af­ford­able. Compared to expensive dedicated hosting options, VPS hosting offers a more cost-effective starting point for smaller projects. Although VPS scaling doesn’t compare with cloud hosting, a VPS plan can be flexibly adjusted to ac­com­mo­date a fluc­tu­at­ing workload.

Dif­fer­ence 3: Data security

Data security is offered by both forms of hosting. However, there is one main dif­fer­ence: Virtual servers store your data on the host server with other customers’ data. Although VPS servers act in­de­pen­dent­ly of each other, data security ul­ti­mate­ly depends on the un­der­ly­ing data center security. A dedicated server uses a single-tenant server en­vi­ron­ment, so you don’t have to worry about possible security breaches in VPS segments or on the host server.

Nev­er­the­less, there are a number of ways you can mitigate security gaps in both variants. You can configure the server’s security standards using security software, SSL, access re­stric­tions, block­list­ing, optimal password pro­tec­tion and data backups. VPS hosting or dedicated server providers usually also have built-in security features as well as ad­di­tion­al security features that are optional.

Dif­fer­ence 4: Costs

Let’s use a metaphor to compare pricing. VPS is like a rented apartment and dedicated hosting is like a rented house. While you share the main building with other residents in an apartment, it is cheaper than a rented house. Dedicated servers usually offer large resources, so this is also reflected in their higher costs. On the other hand, VPS hosting offers a broad range of price plans. VPS servers offer better value for money for newcomers, smaller companies, or projects with fewer or in­cal­cu­la­ble re­quire­ments.

Dif­fer­ence 5: Avail­abil­i­ty

If you want reliable avail­abil­i­ty and fault tolerance, you can’t go wrong with dedicated servers. The dedicated resources are, depending on the server plan, fully available and do not have to be shared with others. This means that if there is high traffic, all resources can be used without any re­stric­tions. Fast loading times are also guar­an­teed. In contrast, a VPS hy­per­vi­sor allocates resources for your server plan. Ad­di­tion­al ca­pac­i­ties can only be used if they are not occupied by other virtual servers.

Sim­i­lar­i­ty: In­di­vid­u­al­iza­tion

Although VPS and dedicated servers both have physical per­for­mance limits when it comes to upscaling, they can both be cus­tomized. Whether you have your own operating systems, scripts, various programs, or modular mi­croser­vices, root access allows for an in­di­vid­u­al­ly con­fig­urable server en­vi­ron­ment with both VPS and dedicated hosting. However, this also means that you need ad­min­is­tra­tive skills to set up and manage your server.

Data pro­tec­tion and data sov­er­eign­ty

In both hosting variants, you are re­spon­si­ble for managing your server. This means you need to ensure com­pli­an­cy with data pro­tec­tion leg­is­la­tion for online services and your business’s online presence. You need to protect customer and visitor data as well as your own business’s data. In addition to firewalls, page cer­tifi­cates, and security features, com­pre­hen­sive data pro­tec­tion and data sov­er­eign­ty also includes storing data in com­pli­ance with the CCPA. If you are pro­cess­ing personal data in the U.S., make sure to inform yourself of the official data pro­tec­tion re­quire­ments.

It is also important to consider the server location for VPS and dedicated servers. In the case of U.S. providers, U.S. au­thor­i­ties have the right to access U.S. owned servers in ac­cor­dance with the Cloud Act.

Is a VPS or dedicated server better suited to business needs?

Depending on the scenario, a virtual or dedicated server may be more suitable. Below are examples for each hosting model:

VPS server

• Demanding tasks like web hosting with your own web server
• Pro­cess­ing data with a data server or an email server
• Managing a small to medium-sized online store
• Using your own game server for game hosting
• Cloud storage
• Test en­vi­ron­ment for programs
• Server for office tasks such as sched­ul­ing
• Managing online com­mu­ni­ties with large, cal­cu­la­ble numbers of visitors
• Medium-sized companies webpages

Dedicated server

• Complex projects such as web servers with high per­for­mance re­quire­ments and fast load times with very high traffic
• Web server for large online stores with a lot of visitors and per­for­mance peaks
• Server for databases
