New L1 module modules/l1/dynamodb/ (stack type aws:dynamodb:table). Terraform aws_dynamodb_table with PK + optional SK, PAY_PER_REQUEST default, SSE-KMS + PITR + prevent_destroy per v1.8 NFR defaults. Registry entry (kind l1), catalog row, test_adapter.py updated to 15 entries / 13 L1. 45 tests passing. ---ci--- project: acdl phase: 2 milestone: v1.26 status: execute phase_role: execution wave: 0 requirements: [REQ-322] ---/ci---

# Nova Modules
|
|
|
|
Reusable building blocks for cloud infrastructure. Each module is
|
|
self-documented with a `README.md` following the
|
|
[template](README-TEMPLATE.md).
|
|
|
|
## How the modules work
|
|
|
|
There are two kinds of module:
|
|
|
|
- **Primitives** — a single cloud resource or a small group of
|
|
related resources (e.g. a VPC with subnets and routing). Each primitive
|
|
has an `interface.json` declaring its inputs and outputs, and a
|
|
`README.md` in plain language.
|
|
- **Modules** — a pattern that references multiple primitives to
|
|
deploy a complete stack (e.g. an ECS Fargate microservice). Each module
|
|
has a `composition.json` declaring its children and wires.
|
|
|
|
The engine adapter (`adapters/terraform/adapter.py`) compiles a
|
|
module instance to infrastructure. Each module's README documents which
|
|
resources it creates.
|
|
|
|
## Primitives
|
|
|
|
| Module | What it creates | README |
|
|
|--------|----------------|--------|
|
|
| `s3` | `aws_s3_bucket` — a single S3 bucket | [README](l1/s3/README.md) |
|
|
| `vpc` | `aws_vpc` + `aws_subnet` + `aws_route_table` + `aws_internet_gateway` — VPC with subnets and routing | [README](l1/vpc/README.md) |
|
|
| `ecs-cluster` | `aws_ecs_cluster` — ECS Fargate cluster | [README](l1/ecs-cluster/README.md) |
|
|
| `ecs-service` | `aws_ecs_task_definition` + `aws_ecs_service` — Fargate service with task definition | [README](l1/ecs-service/README.md) |
|
|
| `iam-role` | `aws_iam_role` — IAM role with assume-role policy | [README](l1/iam-role/README.md) |
|
|
| `alb` | `aws_lb` + `aws_lb_target_group` + `aws_lb_listener` — Application Load Balancer | [README](l1/alb/README.md) |
|
|
| `ecr` | `aws_ecr_repository` — ECR container image repository | [README](l1/ecr/README.md) |
|
|
| `cloudfront` | `aws_cloudfront_distribution` + `aws_cloudfront_origin_access_control` — CloudFront distribution with S3 origin via OAC | [README](l1/cloudfront/README.md) |
|
|
| `waf` | `aws_wafv2_web_acl` — WAFv2 Web ACL (CloudFront-scoped) | [README](l1/waf/README.md) |
|
|
| `rds` | `aws_db_instance` — Relational database (PostgreSQL, MySQL, etc.) with multi-engine support | [README](l1/rds/README.md) |
|
|
| `kms-key` | `aws_kms_key` — Customer-managed KMS key with rotation enabled (per-stack CMK) | [README](l1/kms-key/README.md) |
|
|
| `uptime` | `aws_ecs_service` — Uptime-kuma monitoring on ECS Fargate with alert channels | [README](l1/uptime/README.md) |
|
|
| `dynamodb` | `aws_dynamodb_table` — DynamoDB table with encryption + PITR (v1.8 NFR defaults) | [README](l1/dynamodb/README.md) |
|
|
|
|
## Modules
|
|
|
|
| Module | What it references | README |
|
|
|--------|--------------------|--------|
|
|
| `microservice` | 6 primitives (vpc, cluster, ecr, iam-role, alb, ecs-service) | [README](l2/microservice/README.md) |
|
|
| `static-assets` | 3 primitives (s3, cloudfront, waf) | [README](l2/static-assets/README.md) |
|
|
|
|
## Registry
|
|
|
|
Module versions are tracked in `registry.json`. Both primitives and
|
|
modules are registered.
|
|
|
|
## Template
|
|
|
|
New modules should use [README-TEMPLATE.md](README-TEMPLATE.md) as
|
|
their starting point.
|
|
|
|
## Module patterns (roadmap)
|
|
|
|
The current `composition.json` mechanism is a thin pattern layer. A future
|
|
redesign will let a consumer dynamically create a module directly from the
|
|
contract file (an agentic "composition" flow). That is on the roadmap, not
|
|
implemented today. |
