A virtual private server (VPS) is a dedicated portion of a real server’s resources. The cloud is built on a network of dedicated servers, and you can change the configuration at any time.
Let’s take a closer look at the distinctions between these two technologies:
Scaling: VPS is a closed system with a predetermined setup. Cloud resources are presented as a unified pool that may be scaled up or down at any time.
Data security: VPS takes advantage of both the data center’s and the user’s security safeguards. The cloud provides the same level of security as virtual servers, as well as internal security features like hardware-based encryption.
redundancy: If the host server goes down, all virtual machines go down with it. In the cloud, where several physical servers are used, this is impossible.
Virtualization, which divides servers into virtual machines, underpins both technologies. In the case of VPSs, these machines work in the same way as a dedicated server with a set of parameters. This is why VPS rentals are paid in advance for a set length of time; the configuration never changes. In the cloud, on the other hand, resources can be modified at any time. This is why cloud services are available on a “pay-as-you-go” basis.
What are the advantages and disadvantages of VPS?
Users of VPS/VDS get their own virtual server. A hypervisor, a sort of software that is put on a real server to segment its resources, is used to construct the VPS. The client receives a “slice” of one physical server’s resources. When a client needs additional resources, they place an order for a new virtual server.
Clients are frequently granted root access to their VPS. Users with root access can install an operating system as well as other software on the server. VPS users, in theory, have their own server with dedicated resources and the flexibility to deploy software solutions with no restrictions other than hardware configuration.
Let’s look at some of the advantages of hosting in a secure environment:
All data and services on the same host server are inaccessible to other VPS users; the virtual machine can be launched, rebooted, and shut down independently of other users.
The VPS is connected to the user’s local network; virtual servers can use dedicated IP addresses, routing tables, and other features; other users’ actions have no impact on the resources of your virtual private server.
The cost of VDS is one of its key advantages. VPS configurations are comparable to physical dedicated servers, however, they are less expensive. However, when workloads grow, you won’t be able to scale the resources. The expansion of an IT infrastructure is necessitated by the growth of a business and the increase in traffic. The organization will need to order a new virtual private server (VPS) with different configurations and re-deploy the systems.
VPS is a suitable choice for light workloads like remote desktops and group work with office software, as well as launching small e-commerce ventures, corporate websites, and specific sorts of servers (proxy, mail, monitoring, voice communication, etc).
Video and music streaming, game servers and apps with high or variable traffic, cryptocurrency mining, major e-commerce ventures, and other resource-intensive jobs are frequently not a suitable fit for VDS. The SLA of the provider frequently prohibits this usage. If these rules are broken, the VPS will be shut off to prevent any unwanted consequences on the virtual machines of other users.
Some VPS providers sell their resources too cheaply. Overselling occurs when a provider sells more resources than they can really provide at any given time. Users will be unaffected as long as they do not use all of their resources. Peak traffic loads, on the other hand, will eventually slow down all virtual machines on the same physical server. Clients wind up paying for resources that aren’t available to them, and performance falls short of expectations.
Heavy demands on other users’ VPSs can occasionally cause them to fail. The bandwidth of the disc subsystem and other shared resources on the VPS may be limited as a result of this. Providers try to keep these circumstances under control and prevent them as much as feasible. Nonetheless, a physical server failure will bring all virtual servers to a halt until the host is repaired. The provider is responsible for replacing or repairing faulty equipment. In most circumstances, however, it is the responsibility of the VPS client to set up backups.
Firewalls and DDoS protection, for example, are dependent on the provider. SIM-Networks, for example, rents out a variety of data protection software. Our servers are likewise kept in ISO/IEC 27001-certified data centers. This standard governs the standards for data center security systems.

What issues does the cloud resolve?
The public cloud is a collection of software and technology that is made available to users via the internet. Servers, storage, network infrastructure, apps, and services are all part of this complex, which is portrayed as a single pool. On-demand, the pool’s resources are dynamically divided among users.
Users can set their own configurations, establish bespoke virtual networks using the control panel, and install OS systems and programs utilizing the IaaS (Infrastructure-as-a-Service) concept. Virtual network devices in the cloud can be set up and linked in the same way that real network devices can.
One of the key benefits of IaaS is its flexibility. Without having to contact the supplier, public clouds can be scaled instantaneously to meet the needs of the user. Adding and withdrawing resources is done via the control panel, regardless of the time of day or the user’s location. Clients with high demands for scale, reliability, and performance will be interested in this functionality.
In the cloud, microservices are frequently employed. These services are used to secure data, monitor systems, and perform other activities. Here are a couple of microservices available in the public SIM-Cloud as an example:
VPN-as-a-Service, or VPNaaS, allows customers to quickly set up virtual private networks.
FWaaS (firewall-as-a-service) — filters internet traffic according to security policies;
DNS-as-a-Service, or DNSaaS, allows customers to manage domain setups, as well as add, amend, and delete DNS records, automatically.
Notification-as-a-Service — sends out automatic notifications regarding critical project events.
Clients are typically allowed to install their own microservices in addition to those provided by default. On-demand XaaS services are also available from some providers. Backup-as-a-Service, or BaaS, is the most popular example of such a service. Users do not need to set up their own reserve copying systems; simply select your desired options and backups will be produced automatically.
Because of the cluster architecture, cloud hosting is fault resilient. The availability of cloud services is not dependent on any particular physical equipment, such as a disc array, a server, or a network. If a piece of hardware fails, the workloads are automatically moved to another device. The client’s services will not be harmed as a result of this. Separate cloud availability zones are also available from some providers. An availability zone is a cloud environment that is self-contained and runs on its own hardware. When services are deployed in two availability zones, they are twice as fault-tolerant.
It’s vital to keep in mind that public clouds should not be used to work with sensitive data like banking or medical records. Because data in the cloud is stored alongside that of other users, this limitation applies. In industries that operate with sensitive data, private clouds are employed; in other circumstances, public clouds are used for less sensitive data.
Which is better for my company: the cloud or a virtual private server?
When weighing the advantages of a VPS vs. the cloud for your company, keep in mind that they are two distinct tools that accomplish tasks of diverse types and levels.
VPS is ideal for small applications that do not necessitate a complicated infrastructure solution. Organizing a remote office for a company with 10-20 people is a classic example.
As long as the workloads are generally stable and the setup allows enough flexibility for the project, a virtual server will easily handle it. This is a good solution for smaller businesses that need resources comparable to a dedicated server but don’t want to spend too much money on IT.
The cloud is ideal for large projects with complicated network topologies and high security and scaling requirements. The flexibility to adjust the configuration on the fly will aid the client in adapting to the expansion of their business. Businesses that deal with seasonal traffic will also benefit from this. Users of the cloud can turn off resources they aren’t utilizing and pay less when they aren’t.
