The Technology category in the palette holds full-colour icons for the infrastructure services that show up on system-architecture diagrams: AWS S3, Lambda, EC2, Azure Functions, Kubernetes, PostgreSQL and many more. They sit beside the regular Icons category but are deliberately a separate surface, because they are coloured filled marks rather than the single-weight line art the Icons catalogue holds. An orange Lambda is only recognisable orange, so technology icons keep their fixed brand colours rather than tinting to your theme.
What's in the set
The set covers a curated selection of common services across five providers:
- AWS: S3, EC2, Lambda, RDS, DynamoDB, API Gateway, CloudFront, Route 53, VPC, SQS, SNS, ECS, EKS, CloudWatch, IAM, Lake Formation and MSK.
- Azure: Virtual Machine, Blob Storage, App Service, Functions, SQL Database, Cosmos DB, AKS, Virtual Network, Load Balancer, Service Bus, Key Vault and Monitor.
- Cloudflare: Workers, Pages, R2, D1, KV, Durable Objects, Queues, Zero Trust, CDN, DNS, WAF, Workers AI, Images and Stream.
- Firebase: Firestore, Realtime Database, Authentication, Cloud Functions, Hosting, Cloud Storage and Cloud Messaging.
- Generic: Kubernetes, Docker, PostgreSQL, MySQL, Redis, MongoDB, Cassandra, Kafka, RabbitMQ, Elasticsearch, Nginx, GraphQL, Node.js, React, GitHub, GitLab, Terraform, Prometheus, Vercel and Supabase.
Each icon is a brand-coloured rounded tile with a white line-art symbol, the AWS resource-icon visual language, applied uniformly across all five providers for a cohesive look. The symbols are drawn for livediagram rather than copied from the vendors' logos.
Adding one
Rest on Tech on the palette strip, or click it. (The category is labelled Tech for width; it is the Technology catalogue this page describes.) It is in the palette in Diagram mode.
Pick a provider (AWS, Azure, Cloudflare, Firebase or Generic) from the list down the side to see its icons, or type in the search box to look across all of them at once. Tech reopens on the provider you last had open.
Click a tile, then click the canvas to drop it there or drag to draw it at the size you want. You can also drag a tile straight onto the canvas.
The Technology grid shows three icons across with a caption under each, since brand icons aren't always self-explanatory at thumbnail size. A few long names use a shorter caption (Virtual Machine shows as VM, Load Balancer as Load Bal.), but the full name is always used for search and for the placed element's label.
You don't need the category to find one. The editor's Search panel and the palette strip's Search both find technology icons by name in any mode, so "database" turns up PostgreSQL, MySQL and the rest.
Working with them on the canvas
- A technology icon is the same kind of element the regular Icons category produces, so there's no new element type to learn.
- It arrives labelled with the service's name, in a band below the icon: the architecture-diagram convention of icon on top, caption beneath. Double-click to change it to something specific, such as
Orders DB. - The mark itself stays a fixed size, so it never warps however you resize the element; resizing only changes the room around it and the caption. To make the mark bigger or smaller, right-click it and pick Small, Medium, Large or Huge in its Icon section.
- A technology icon is always a standalone element: unlike a line-art icon, it never folds inside a shape as an inline icon, and dragging an existing one over a shape leaves it standalone.
The Cloud architecture starter template seeds some of these branded tiles, so a developer audience lands on a diagram that already speaks their stack. Brand tiles keep their colours even when you change the tab's theme.
