No one-size-fits-all when it comes to cloud virtual machines (VMs). Hence the need to select a cloud VM that can serve your workloads and applications properly. Before diving deep into the various optimized cloud VM types for heavy workload applications, let’s go over the concept of cloud VMs, uses cases, and why we need them optimized.

What is Cloud Virtual Machine?


Cloud Virtual Machine (VM) is a physical computer that runs on a remote server somewhere in the cloud, allowing users to run operating systems and applications. They simply simulate the environment of a physical device and give the users access to computing resources remotely via the internet.

Cloud VMs are much more efficient and cost-effective than physical computers because they are shared between users and not managed by the users, taking out the cost and engineering of acquiring and setting up these servers. 

Benefits of Cloud VM


Cloud VMs are much more cost-effective compared to setting up physical hardware and devices. The Cloud VMs operate a pay-as-you-go (PAYG) model, meaning users only pay for the resource they use and nothing more, unlike when it involves the users setting up the hardware themselves.

These services are shared among multiple users making the cost distributed and a much more economical choice for businesses and organizations.


An essential advantage of Cloud VMs is that they are highly scalable, allowing users to increase or remove resources when needed. Businesses with varying workloads could benefit from this as they have the resources to expand when required and reduce when not. While still leveraging on paying for only services used at a particular instance.


Cloud VMs are used for various purposes, making them flexible. They allow users to run different operating systems and software in varying environments. This flexibility makes testing and development more accessible and helps businesses adapt to changing requirements in hardware.

Choosing a Cloud VM


The following factors are worth considering when deciding on the Cloud VM to be used on any project.


Cloud services operate a PAYG model. Nevertheless, you must consider the pricing per service before settling on the provider to use cause it could cost from a few dollars to hundreds per month depending on usage – which brings us to the next factor. 


The type of workload that you need to run will determine the type of VM you need. Different cloud VMs are optimized for certain workloads, such as:

  • General purpose – Balance CPU-to-memory ratio.
  • Compute-optimized – High CPU
  • Memory-optimized – High memory
  • Storage optimized – Higher disk space
  • Cost-optimized – Low-cost priority 
  • Accelerator optimized – High-performing GPU
  • High performance, fastest, and most powerful CPU

A high-performance computing VM is ideal for big data companies because of the powerful CPU. A GPU-optimized VM is the best if you are a graphic designing company. Hence, the user/businesses must factor in their use case to select the right VMs


Cloud VMs are secure and essential for businesses with sensitive data. Users must know the security architecture of the cloud provider of choice to learn how security issues are handled.

Ensure that your infrastructure can withstand attack and fight it off without losing sensitive data to malicious actors. Also, consider the provider’s reputation, SLAs, failover strategy, and other critical elements that impact your data’s security.

Different Cloud VMs are optimized based on certain functionalities. In this section, we will go through some VMs and learn their specification and best-fit use cases.
