Comparison between Dedicated Server and Cloud Server

11 Jun

Let’s draw a comparison between the two services – cloud server and dedicated server–on the parameters affecting the performance of the application that run directly on these servers.
Comparison between Dedicated server and Cloud Server
Scalability
Vertical scaling is offered in cloud. This means scalability of key computing resources, memory, disc space, etc. Just by mere rebooting this can be done. Even horizontal scaling is possible. This refers to multiple instances of the same configuration cloud instance available to handle huge customer base across various locations.

The hardware specs are predefined in dedicated hosting. Migration of data, installation, etc. is required in horizontal scaling.

Industry Standards and Compliance
In cloud server hosting, computational resource pool and common storage pool is shared. This risk can be mitigated using Hybrid Solutions. Whereas in dedicated server, software and hardware are fully dedicated, hence the compliance standards are of highest order.

Performance
Given the same resources, cloud server hosting provider will definitely show a lag in performance because of I/O specially websites with high database usage. Whereas in dedicated hosting, higher database usage websites and hardware intensive applications perform better.

Availability
Because of the very nature of resource pool cloud server scores better than the dedicated server. In Even a single node failure will be disastrous in dedicated server hosting.

Cost
Flexible billing as per use is followed in cloud server hosting, scaling the resources up and down makes it a cheap yet stable option. On the contrary, hardware cost is more in dedicated connection. Scaling up or down is complicated.

Restoration/ Replication – To create a snapshot or restore from a backup takes less time in shared server. In dedicated server, OS and other software need to be re-installed and restored.

Keeping these differences in mind, one should choose smartly between the two services as per the business requirement.
