+## AWS ECS deployment steps: 
+
+ECS: Elastic Container Service
+Steps after docker images are available on Docker Hub
+
+### Step 1. Create a new ECS task definition
+   - Task name (e.g. ObjectDetectionDETRTask)
+   - Infrastructure requirement: 
+     - Launch type: ```AWS Fargate```
+     - Architecture: ```Linux/X86_64```
+     - Task size: ```0.5 CPU, 3GB memory```
+   - Container:
+     - Container name:  (e.g. ```object-detection-detr```)
+     - Image uri: point to Docker image URI (e.g. ```cvachet/object-detection-detr-api```)
+     - Port mapping: assess port number (e.g. ```port 8000, TCP protocol```)
+     
+
+### Step 2. Create a new ECS cluster
+   - Cluster name (e.g. ```ObjectDetectionCluster```)
+
+
+### Step 3. Add a new service to the cluster
+ - Compute configuration
+   - Use capacity provider strategy (e.g. using Fargate or Fargate_spot)
+ - Deployment configuration
+   - Application Type: Service
+   - Task Family: Select task definition family from prior instance (e.g. ```ObjectDetectionDETRTask```)
+   - Assign a Service Name: (e.g. ```object-detection-detr-api```)
+
+
+### Step 4. Update security group for new service
+ - Go to Cluster -> service -> task -> configuration and networking
+ - Click on ```Security Group```
+ - Adjust rules for inbound traffic (e.g. traffic only from my_ip)
