Canvas & Design

Architecture Canvas Drag-and-drop cloud architecture diagrams with live cost estimates.

Databases & Caching

Postgres Limits Connection, memory, and storage limits for PostgreSQL. Zero-Downtime Postgres Analyze table lock risk and generate zero-downtime PostgreSQL migrations. Redis Sizing Memory sizing and eviction planning for Redis. ES/OpenSearch Shard and heap sizing for Elasticsearch/OpenSearch. Cassandra Storage Storage and replication sizing for Cassandra clusters. MongoDB Sharding Sharding strategy and capacity planning for MongoDB. DynamoDB Capacity Read/write capacity units and cost for DynamoDB. Connection Pool Sizer Right-size database connection pools for your workload. Read Replica Sizer Size read replicas, throughput splits, and connection pools.

Event Streaming & API

Kafka Partitions Partition count and throughput planning for Kafka. Queue Drain & Lag Sizer Calculate consumer concurrency and drain time for Kafka, RabbitMQ, and SQS backlogs. RabbitMQ Memory Queue memory and throughput sizing for RabbitMQ. Kinesis Data Streams Shard count and cost planning for Kinesis Data Streams. Rate Limit Sizer Size token-bucket and sliding-window rate limits. SQS & DLQ Sizer Calculate optimal visibility timeouts, retries, and DLQ triggers.

Compute & Serverless

K8s Bin-Packing Pod bin-packing and node sizing for Kubernetes. K8s Ingress & TLS Builder Generate Kubernetes Ingress, path routing, and cert-manager TLS manifests. Serverless Power Find the optimal memory setting for AWS Lambda. CF vs Lambda Compare CloudFront Functions vs Lambda@Edge cost and latency. WebSocket vs SSE Sizer Compare WebSockets vs SSE vs Long-Polling memory, bandwidth, and cost.

Networking & Storage

Vercel vs CloudFront Compare Vercel vs CloudFront hosting cost and performance. API Gateway vs ALB Compare API Gateway vs ALB cost at scale. Egress Shock Estimate cloud egress bandwidth cost before it surprises you. S3 vs Glacier Compare S3 storage classes vs Glacier retrieval cost. Retry & Backoff Model retry and exponential backoff behavior under failure. CDN Cache Hit Ratio Estimate cache hit ratio, origin offload, and CDN cost savings. Cache-Control Builder Build and visualize HTTP Cache-Control & CDN edge directives. S3 Multipart Sizer Calculate optimal S3 multipart upload chunk sizes and thread concurrency.

Traffic & Scaling

Load Balancer Visualizer Simulate round-robin, weighted, and least-connections routing. Autoscaling Group Sizer Size min/max/desired instance counts from load and utilization targets.

Observability & Analytics

Metrics Cardinality Estimate metrics cardinality cost for Prometheus/Datadog. Athena Query Trap Estimate Athena query cost from data scanned. Snowflake vs Redshift Compare Snowflake vs Redshift compute cost. Log Ingestion Cost Estimate log ingestion cost across observability platforms.

Security & Keys

KMS Encryption Estimate AWS KMS encryption request cost.

About the Architecture Suite

36 calculators for sizing databases, message queues, compute, and network infrastructure before you commit to a configuration — plus an interactive canvas for sketching a system and seeing its estimated monthly cost. All calculations run client-side using published pricing and capacity formulas.
