Frequently Asked Questions
- What should a cloud architecture diagram include?
- A good cloud architecture diagram should include compute resources (servers, containers), storage systems, databases, networking components (VPCs, subnets, load balancers), security boundaries, data flow arrows, and external integrations. Label each component clearly and show how they connect.
- What tools can I use to create cloud architecture diagrams?
- Popular tools include Canvas Cloud AI (AI-powered diagram generation from text), Lucidchart, draw.io, Cloudcraft, and each cloud provider's native tools. Canvas Cloud AI can generate diagrams from plain English descriptions and supports AWS, Azure, GCP, and OCI.
- How often should architecture diagrams be updated?
- Architecture diagrams should be updated whenever significant infrastructure changes are made. Many teams automate this by generating diagrams from Infrastructure as Code (Terraform, CloudFormation) so they stay in sync with actual deployments.
