For example, the cloud server can be scaled up and down at any time to meeting the changing needs due to the scalability of the cloud.

Enterprises can also apply multiple data security solutions with cloud computing to enjoy all-round data protection.

It is always suggested that the data and workloads can be even more secure to be placed on the cloud with complete security solutions like users can always restore all the data from a simple Backup.

Linode offers five kinds of cloud computing solutions like general server, high memory servers, dedicated CPU or GPU servers to target different cloud usage.

In fact, a dedicated GPU server is rare in the cloud computing industry. Compare to the other cloud providers tested, Linode has nice in-house monitoring and provide up-to-date tech support,

it does also provide free server upgrades in most of the case. Moreover, it is the only provider that can feature NodeBalancer from the working platform.


DigitalOcean is an American cloud infrastructure provider founded in 2011. It collocates the cloud server in 13 data centers, 4 of them are in Europe and 2 in Asia (DigitalOcean, 2000).

DigitalOcean offers 5 server plans for different segments, such as general droplet, CPU or memory optimized droplet.

CPU Comparison

CPU is another important factor to judge cloud performance. As to create a comprehensive picture for audiences,

an independent and authoritative CPU benchmarking platform – PassMark Software has been used to evaluate the CPU applied to cloud server by top providers (PassMark Software, 2021).

Result From PassMark Software (

Vultr is absent from the table because its cloud servers are powered by Intel Skylake processors (Virtual CPU a7769a6388d5 and 6db7dc0e7704) which are not selectable on PassMark, so I cannot compare all of them on a single platform.

According to the comparison, LayerStack is using the best CPU in both standard plan and CPU optimized plan with AMD EYPC 7702 and 7742 respectively.

They are rated much higher than the CPUs used by DigitalOcean and Linode. Linode gets the second place on this CPU comparison, while DO is in the last place.

Feature Comparison

Cloud providers are offering diverse cloud features and add-ons aiming to enhance cloud efficiency and data security.

In most cases, users just need to pay a small cost or even free to enjoy powerful features like private networking, auto-backup and DDoS protection.
