Dedicated Server vs VPS vs Cloud – a comparison
In this era of tightly restrained budgets, when it comes to selecting a server for your website or an application, it actually becomes difficult to select the ‘most efficient’ out of many. Moreover, the business of today–from enterprise level to small and medium sized ones, need such an architecture that has the elasticity to cope with the modern demands of the security, business on the go, instant and unlimited scalability, business agility and more.
Web hosting industry provides various options, but we’re discussing only three main ones in this article:
- Traditional hosting –Virtual private servers (VPS) and dedicated servers.
- Advanced hosting – Cloud servers.
It is the comparison that helps people make more informed decisions. So let’s investigate the three different servers- Dedicated Server vs VPS vs Cloud :
Virtual Private Server – a townhome of the hosting industry
A virtual private server is a virtualized server which an internet hosting provider sells as a ‘service’ by partitioning a single server into multiple servers for their respective customers.
Each VPS runs its own operating system and customers are given user- access to administer their operating systems independently and install any software that’s able to run on that OS.
Thus, you get your own set of services, more control over your website with allocated resources and customizable disk space, which you do not share with other ‘neighbors’ on the same single machine.
Key features of a virtual private server:
- State of the art virtualization
- Feasible custom firewall configurations
- Super-user root access
- Dedicated resources in shared environment
- Worry-free environment as server monitoring is managed by the hosting provider.
Limitations of a VPS:
- As multiple virtualization clients run their OS on a single machine, a VPS generally has limited processor time,RAM, and disk space.
- Although you get more control on your website and space, your space on the physical server is technically shared with the neighbors on the board. So it might lower performance or security, affected by the workload of other instances.
Dedicated server–a bungalow of the hosting industry
As the name suggests, a dedicated server is a server dedicated for the exclusive use of its buyer i.e. a client buys a complete server and uses its resources and space without sharing them with anyone else.
When a dedicated server is bought, it comes with a memory with the stated amount, hard disk space, and bandwidth- gigabytes of data to be delivered each month. It is a more flexible option than VPS as it gives full control over the server, including choice of operating system, hardware and other resources.
Key features of a dedicated server:
- Higher level of security and privacy as it is the ‘server under your control’
- Full root admin access
- Customizable server environment
- Enhanced performance and reliability
- Each server comes with unique IP address (important for large organizations running an e-commerce site that requires SSL for credit card processing)
- Eliminates bad neighbor issues.
Limitations of a dedicated server:
- Most expensive among available server options.
- Extensive networking knowledge and skills are a must to manage dedicated server and websites hosted on
- Difficult to fix when it crashes.
Cloud server-a luxurious vanity van
Cloud is a network of multiple independent and remote servers that enable processing of shared resources (networks, servers, storage, applications and services) and data to the customers on demand via any network i.e. internet.
It allows centralized data storage, and online access to computer services or resources.
There are three types of cloud deployment models :
- Public cloud- Services are provided via a network for the public use.
- Private cloud – Cloud infrastructure that operates solely for a single organization.
- Hybrid cloud- Perfect blend of public and private cloud.
Key features of cloud hosting:
- Cost efficiency.
- Improved business agility.
- Device and location independence.
- Improved scalability and flexibility.
- Disaster recovery.
- Guaranteed no single point of failure.
Limitations of cloud hosting:
Not considered very secure, limited control and vendor lock-in.
A brief comparison-Dedicated server vs VPS vs Cloud
|Comparative Features||Virtual Private Server||Dedicated Server||Cloud Server|
|Cost||Low in comparison to dedicated and higher than shared hosting||Costliest option||Considered a cost –efficient option as based on ‘pay as you use resources’ model.|
|Scalability||Instant but limited||More than VPS||Scale up and down immediately as per your business needs.|
|Level of security||Lesser than dedicated||Highest level||Public Cloud– as secure as the network.
Private Cloud-Highly secure.
|Remote access||Available||Available||Access your business and expand on the go with its tools-Office 365 and Microsoft Azure.|
|Level of control||Lesser than Dedicated.||Highest level||Lesser than Dedicated.|
|Best suited to||Moderate traffic with occasional spikes.||Heavy traffic and high CPU usage websites, ecommerce sites or sites with sensitive information.||All types of websites.|
Which hosting environment is best for me?
The type of the server option to be chosen depends on the traffic needs and nature of your website. So judge your website requirements and decide intelligently.
However, it is always wise to choose that option which meets all your requirements. As per my recommendation, cloud hosting is the best option to choose as it comes with top of the line productive tools that help you to expand you business and collaborate with your team on the go, at reduced cost.
Looking forward to your comments.
