A Virtual Private Server (VPS) is a virtualized server that provides dedicated resources — including CPU, RAM, and storage — within a shared physical machine. It combines the affordability of shared hosting with the control and performance of a dedicated server.
For growing businesses, developers, and cloud teams, VPS hosting often represents the first step ahead of shared hosting, and the foundation for more advanced cloud infrastructure.
A Virtual Private Server (VPS) is a type of web hosting that uses virtualization technology to partition one physical server into multiple isolated virtual environments. Each VPS acts as its own independent server, with its own operating system, dedicated resources, and full root access, even though it shares underlying hardware with other users.
Think of it like an apartment building: each tenant has their own private, self-contained unit with their own key, but the building's physical structure and infrastructure (plumbing, electrical, foundation) are shared. VPS hosting works the same way.
A VPS uses a technology called a hypervisor, software that creates and manages virtual machines on a physical server.
The hypervisor (such as VMware, KVM, or Hyper-V) divides the physical server's hardware into isolated compartments, each acting as a fully independent virtual machine.
Here's what happens under the hood:
This model eliminates the “noisy neighbor” problem common in shared hosting environments. What happens on one virtual machine does not impact others running on the same physical hardware.
Understanding VPS is easier when compared to the two main alternatives:
All users share the same resources. If one site experiences a traffic spike, others may slow down.
Resources are isolated and allocated. Performance is predictable and customizable.
You control the entire physical machine. It’s ideal for large-scale, resource-intensive applications.
Not all VPS plans are the same. Here are the main types to know:
The hosting provider handles server maintenance, security patches, updates, and technical support. Best for users who want power without the system administration burden. Ideal for small business owners and non-technical users.
You are responsible for configuring, maintaining, and securing the server yourself. Requires Linux/server administration knowledge. Best for developers and system administrators who want maximum control and customization.
Resources are distributed across multiple physical servers in the cloud, providing high availability and easy scalability. You can scale resources up or down instantly. Providers include Hostinger, Cloudways, A2 Hosting, and DigitalOcean (whose "Droplets" straddle the line between cloud VM and VPS due to their hosting-friendly UX and simple flat-rate pricing).
This is one of the most commonly misunderstood distinctions in web hosting and understandably so, because the terms are often used interchangeably. In reality, a Cloud VPS and a Cloud VM (Virtual Machine) are technically very similar, but they differ significantly in how they're packaged, managed, and who they're designed for.
Both a Cloud VPS and a Cloud VM are virtualized computing environments running on shared physical infrastructure. Under the hood, they use the same core technology — a hypervisor that partitions a physical server's resources into isolated virtual instances. So at the infrastructure level, the difference is more about product positioning and management experience than fundamental architecture.
A Cloud VPS is sold by web hosting companies (Hostinger, A2 Hosting, Cloudways, SiteGround) and is designed to make server management accessible. It typically comes with:
Cloud VPS is aimed at website owners, small businesses, and developers who need server power without deep infrastructure expertise.
A Cloud VM (also called a cloud instance or compute instance) is sold by cloud infrastructure providers (AWS EC2, Google Compute Engine, Microsoft Azure VMs, DigitalOcean Droplets, Vultr Cloud Compute). It is a raw virtualized server with:
Cloud VMs are aimed at developers, DevOps engineers, and enterprises building scalable, cloud-native applications and infrastructure.
Choose a Cloud VPS if you want to host a website, run a web application, or manage a server without getting deep into cloud infrastructure. It's simpler, more affordable for most use cases, and comes with hosting-centric tools that make your life easier.
Choose a Cloud VM if you're building scalable software, need to integrate with a broader cloud ecosystem (databases, object storage, serverless functions), or require fine-grained control over your infrastructure. It's the right tool for engineering teams building production-grade, cloud-native systems.
Unlike shared hosting, your allocated CPU and RAM are yours. Other users on the same physical machine cannot consume your resources, ensuring consistent performance.
You have complete control over your server environment. Install any software, configure firewalls, set up custom security rules, and modify server settings at will.
Most VPS providers allow you to upgrade your plan — adding more CPU cores, RAM, or storage — without migrating to a new server or experiencing downtime.
Isolation from other users means you're not affected by their security issues. You can also implement your own firewall rules, SSH key authentication, and intrusion detection systems.
With guaranteed resources and SSD storage, VPS hosting delivers faster load times and better handling of traffic spikes compared to shared hosting.
You can install any operating system, control panel (cPanel, Plesk, Webmin), or application stack (LAMP, LEMP, Node.js, Python, etc.) that meets your needs.
VPS is significantly more affordable than a dedicated server while offering similar control and performance. It's a cost-efficient step up from shared hosting for growing businesses.
VPS hosting supports a wide range of workloads:
For compute-heavy use cases, VPS can serve as the baseline before moving to GPU-backed cloud instances.
As teams grow beyond a single website or application, VPS environments rarely stay simple. What starts as one virtual server can quickly become:
Managing this manually across different dashboards and billing models introduces operational overhead and risk. For teams that have outgrown a single VPS or a single cloud provider, emma removes the operational friction that comes with managing compute infrastructure across fragmented cloud environments
While emma does not manage retail VPS hosting plans from traditional web hosting providers, the platform enables teams to deploy and manage VMs across multiple cloud environments from a single control layer.
With emma, teams can:
Instead of managing instances separately inside each cloud console, emma provides centralized orchestration, governance, and optimization. For growing teams, this removes the operational friction of managing infrastructure across siloed environments.
When evaluating VPS hosting providers, consider these key factors:
Performance & Hardware — Look for NVMe SSD storage, modern CPU generations (Intel Xeon or AMD EPYC), and high RAM capacity.
Network Speed & Uptime — Choose providers that guarantee at least 99.9% uptime and offer high-bandwidth network connections (1 Gbps or more).
Data Center Locations — Select a provider with data centers close to your target audience to minimize latency.
Scalability Options — Ensure you can easily upgrade (or downgrade) resources as your needs change.
Support Quality — For managed VPS, 24/7 support via chat or phone is essential. Check reviews on platforms like Trustpilot and G2.
Pricing Transparency — Watch for hidden fees on backups, IP addresses, or control panels. Compare monthly vs. annual billing.
Popular VPS Providers to Consider: Hostinger, A2 Hosting, Cloudways, SiteGround, InMotion Hosting, and DigitalOcean. If you need raw cloud infrastructure rather than managed hosting, look at AWS EC2, Google Cloud Compute, or Microsoft Azure — but note these are cloud VMs, not pure VPS products.
A VPS is the right choice if you check any of these boxes:
On the other hand, shared hosting is sufficient if you're running a simple personal blog or informational website with low traffic, and a dedicated server is better if you're running regulated or enterprise-scale applications that require maximum isolation and/or raw performance.
A Virtual Private Server (VPS) bridges the gap between shared hosting and dedicated infrastructure. It provides dedicated resources, cost efficiency, full administrative control, better performance consistency, and improved security
For developers, startups, and growing businesses, VPS hosting offers the flexibility needed to scale without the overhead of managing physical hardware. As infrastructure grows across regions and providers, platforms like emma ensure VPS environments remain scalable, governed, and cost-optimized, without adding operational complexity.
VPS stands for Virtual Private Server. It's a virtualized server environment that provides dedicated resources within a shared physical machine.
Not exactly. A cloud server distributes resources across multiple physical machines for higher redundancy and scalability. A traditional VPS typically runs on a single physical machine. However, many providers now offer "cloud VPS" plans that combine both concepts.
VPS hosting typically ranges from $5 to $100+ per month, depending on the allocated resources (CPU, RAM, storage), provider, and whether the plan is managed or unmanaged.
For managed VPS, minimal technical knowledge is required — the provider handles server administration. For unmanaged VPS, you should be comfortable with Linux command-line operations, server configuration, and basic security practices.
VPS hosting is significantly more secure than shared hosting because each instance is isolated. However, security ultimately depends on how well you configure and maintain your server.
