Published: 2023-09-22 13:08:22

Diagramming tools for cloud infrastructure have been around for quite some time. They simplify the comprehension and visualization of the intricate subject of cloud architecture. You're likely acquainted with tools like Draw.io, Visio, and Lucidchart, which have been in existence for over a decade. 

In the interim, the cloud market has undergone significant transformations, with the emergence of numerous new cloud service providers like OVH, Digital Ocean, Linode, Scaleway, OCI, along with the introduction of fresh APIs for querying cloud consoles, price data, and the standardization of Infrastructure as Code (IaC). Additionally, cloud providers have expanded their geographical reach by opening more regions.

These developments have created opportunities for advanced diagramming software that serves broader purposes beyond producing static representations of cloud infrastructures.

Modern diagramming tools should mimic the dynamism of cloud infrastructures. They should possess the capability to interact with cloud platforms, enabling the import and export of cloud resources. Additionally, they should offer cost estimates for cloud deployments, support multi-cloud environments, abstract the intricacies associated with various cloud providers, and be compatible with Infrastructure as Code (IaC).

With this vision in mind, my two co-founders and I have developed Holori, a cutting-edge diagramming tool. In this article, we will evaluate various diagramming tools while maintaining an objective perspective. You'll notice that we provide praise for competing tools where it's due.
