 ### Single Node setup
 ![Single Nodes Deployment](./doc/assets/Architecture-Single-BNB-Node-Runners.drawio.png)
 
-1. The AWS Cloud Development Kit (CDK) is used to deploy a single node. The CDK application stores assets like scripts and config files in S3 bucket to copy them to the EC2 instance when launching a BNB Node.
-2. A single RPC BNB Fullnode is deployed within in the [Default VPC](https://docs.aws.amazon.com/vpc/latest/userguide/default-vpc.html) and continuously synchronizes with the rest of nodes on BNB Blockchain Network through [Internet Gateway](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html).
-3. The BNB node is accessed by dApps or development tools internally. JSON RPC API is not exposed to the Internet to protect the node from unauthorized access. dApps need to handle user authentication and API protection, like [in this example for dApps on AWS](https://aws.amazon.com/blogs/architecture/dapp-authentication-with-amazon-cognito-and-web3-proxy-with-amazon-api-gateway/).
-4. The BNB node send various monitoring metrics for both EC2 and BNB client to Amazon CloudWatch.

 ### Highly Available setup
 
 ![Highly Available Nodes Deployment](./doc/assets/Architecture-HA-BNB-Node-Runners.drawio.png)
 
-1. The CDK is used to deploy highly available (HA) architecture. An S3 bucket is utilized to store [User data](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.html) and othether script and configuration files required when launching EC2 as the BNB Node.
-2. A set of RPC BNB Fullnodes are deployed within the [Auto Scaling Group](https://docs.aws.amazon.com/autoscaling/ec2/userguide/auto-scaling-groups.html) in the [Default VPC](https://docs.aws.amazon.com/vpc/latest/userguide/default-vpc.html) continuously synchronizes with the rest of nodes on BNB Blockchain Network through [Internet Gateway](https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html).
