What is a Virtual Private Server (VPS)? Explained in detail by Digimagg

What is a Virtual Private Server (VPS)?

A virtual private server (VPS) is a server that contains all the necessary software and data to operate an application or website. It's termed "virtual" because it utilizes only a portion of the server's physical resources, which are overseen by a third-party provider. Nonetheless, users have access to their dedicated resources on this hardware.

What are the applications of a VPS?

Below are some instances where VPS servers are utilized:

Launching web applications

VPS servers are commonly employed to deploy and operate web applications. For instance, Gourmeat, a gourmet meat store in the United States, utilized Amazon VPS services to establish an inventory management system swiftly. Previously, they managed inventory using spreadsheet reports from individual suppliers. Their cloud-based inventory application integrates these reports, streamlining inventory management, and granting key decision-makers simultaneous data access.

Creating test environments

   With a VPS server, you can efficiently develop and test new applications. Bugout.dev, a startup in the United States, developed a search engine for developers. They regularly conduct experiments to evaluate new features and enhance search functionality for their users. Given the high rejection rate of these experiments, they conduct them in a virtual private server environment to minimize costs.

Providing secondary storage

   A virtual private server can serve as secondary storage for data files. For instance, it can function as a file, image, or email server, establishing secure, accessible, and centralized storage for a group of users.

What is VPS hosting?

When developing a website or web application, customers typically need to set up a database, configure a web server, and incorporate their code. Managing physical server hardware can be intricate and costly. To address this issue, hosting providers oversee the underlying hardware and enable users to utilize these resources. With VPS hosting, each user receives a virtual machine equipped with dedicated resources, allowing them to swiftly deploy and configure their application or website. Consequently, customers utilizing VPS hosting can concentrate on their applications or websites without expending time and effort on managing the physical servers hosting their code. VPS hosting providers ensure secure, reliable, and consistent performance for their clients' websites.

How does VPS hosting differ from other hosting options?

Servers typically possess more memory, processing power, and storage than what's necessary for a single website. Web hosting providers allocate these resources among different customers using various hosting arrangements. Apart from VPS hosting, two other types of web hosting solutions exist.

Shared hosting

In shared hosting, all websites share the same physical server and compete for essential resources like memory, hard disk space, and processing power. The drawback of this hosting service is that other websites sharing the hardware can impact your website's performance.

Shared hosting is akin to watching a movie while seated on a couch with friends. Sometimes, one friend may stretch out and occupy more space, causing discomfort for the others until they readjust.

Dedicated hosting

With dedicated hosting, you rent the entire physical hardware for your use. The web hosting provider grants you exclusive access to the entire physical server, ensuring your website's performance is unaffected by other websites' behavior.

Dedicated hosting is like having the entire couch to yourself—it's comfortable but expensive, and you don't really need all that extra space.

VPS hosting vs. shared hosting vs. dedicated hosting

VPS hosting falls between shared and dedicated hosting. It involves compartmentalizing the single physical server so each website owner perceives it as a dedicated server. You gain exclusive access to your portion of hardware and resources, even though the rest of the physical server is shared.

A VPS hosting service is comparable to reserving a first-class cabin on a luxury flight. While other passengers may be aboard the flight, no one can share your cabin. Furthermore, your cabin can expand or shrink according to your needs, allowing you to pay for precisely what you require!

When is it advisable to transition to VPS hosting?

If you're currently utilizing a shared hosting service and a dedicated server isn't feasible within your budget, transitioning to a VPS hosting plan could be a viable option if you aim to achieve the following:

Manage increased website traffic

While shared hosting may suffice initially, the performance of your website may diminish as traffic escalates. As your website expands and visitor traffic rises, users may encounter prolonged page load times and increased wait times. Conversely, VPS hosting enables your site to outperform shared hosting by efficiently handling higher request volumes.

Customize applications

Compared to shared hosting, VPS hosting affords you greater control over your web server environment. You can implement custom software and configurations, ensuring better compatibility with integrations such as bookkeeping or CRM systems. Additionally, you can implement tailored security measures and firewalls for enhanced system protection.

Mitigate server errors

As your website grows, the addition of more content or complex functionality may elevate processor or memory requirements, potentially resulting in server errors on shared hosting platforms, such as internal server errors or service unavailability. Conversely, compute-intensive websites experience enhanced performance on VPS hosting as they no longer contend with other sites for processing power. Furthermore, with VPS hosting, you have the flexibility to migrate to a new virtual machine with greater processing power as your site continues to expand.

What types of VPS hosting exist?

Three primary forms of VPS hosting are available:

Unmanaged VPS Hosting

In unmanaged or self-managed hosting, the business owner assumes responsibility for all server-related tasks and maintenance. The hosting provider oversees solely the physical server and its availability. Unmanaged VPS hosting necessitates technical expertise or dedicated in-house resources for managing server memory, the operating system, and other server resources. It is best suited for established businesses equipped with the necessary IT capabilities.

Managed VPS Hosting

Fully managed VPS hosting minimizes the time, effort, and technical expertise required to manage your server. The managed VPS hosting provider handles all server-related responsibilities, including core updates, maintenance, and software installation, allowing you to focus entirely on business growth. Managed VPS hosting offers a hands-off approach to server management.

Semi-Managed VPS Hosting

Semi-managed VPS hosting bridges the gap between fully managed and unmanaged hosting. While offering the same fundamental services as unmanaged hosting, the hosting company supplements it with core software installation and support. Additional services typically include:

Services under semi-managed VPS hosting encompass:

• Performing operating system updates and patches
• Implementing security enhancements
• Offering comprehensive web server support
• Monitoring server events
• Providing proactive responses and server restoration as needed.

However, it's important to note that while core managed hosting includes these services, it does not cover aspects like virus and spam protection, external migrations, full control panel support, or control panel upgrades and patches.

Is VPS hosting secure?

Yes, VPS hosting offers security as each instance is isolated from other environments on the server. Unlike shared hosting where your website shares resources with others, VPS protects you from vulnerabilities in other websites. Additionally, you can enhance security with firewalls, antivirus, and other software measures. For instance, in a denial of service (DDoS) attack, shared hosting may cause your system to crash if another website is targeted, as resources are shared.

Is VPS hosting known for its speed and reliability?

Indeed, VPS hosting offers both speed and reliability due to the allocation of dedicated bandwidth to each user. This ensures consistent performance comparable to that of a dedicated server. Additionally, users have the flexibility to select different operating systems and customize server configurations, enhancing application performance accordingly.

Why should you choose VPS?

VPS hosting offers affordable access to a dedicated team of server management professionals, providing several advantages:

• Access to updated best practices and emerging technologies in VPS hosting.
• 24/7 support to minimize downtime and address any issues promptly.
• Optimization of your environment for enhanced performance and security by the VPS hosting provider.
• Allows your IT team to focus on your web application without managing VPS hosting.
• Quick troubleshooting and resolution of common issues by the VPS hosting provider.
