The Significance of Hyperledger Fabric

With so much being said about AWS blockchain templates, let’s move towards the other contributor in AWS Hyperledger Fabric relation. Hyperledger Fabric is basically the blockchain framework capable of running smart contracts known as chaincode. The smart contracts or chaincode on Hyperledger Fabric are scripted by using the Go programming language. 

Users could easily create private networks with Hyperledger Fabric. Therefore, it is clear that Hyperledger Fabric allows the options for restricting the number of participants eligible for connecting to and participating in the network. So, if you want to deploy Hyperledger Fabric applications on the cloud, then the AWS blockchain template for Hyperledger Fabric is your ideal pick. 

The Hyperledger Fabric AWS blockchain template supports a ‘docker-local’ container platform, a unique achievement. The unique facet with the AWS Hyperledger Fabric blockchain template ensures that Hyperledger Fabric containers can be deployed only on a single EC2 instance.

Components in AWS Blockchain Template for Hyperledger Fabric

The next important point of concern in the AWS Hyperledger Fabric tutorial refers to the components. The components of AWS blockchain template built for Hyperledger Fabric blockchain network applications. The AWS Blockchain Template for Hyperledger Fabric establishes an EC2 instance by using Docker. 

In addition, the AWS Blockchain Template also triggers a Hyperledger Fabric network by leveraging containers on the concerned instance. Another critical component addition in the network refers to one order service and three organizations. The three organizations feature one peer service, each as a unique differentiator. Furthermore, the AWS blockchain template also sets up a Hyperledger Explorer container. 

The Hyperledger Explorer container is a suitable instrument for helping users with blockchain data browsing functions. Interestingly, the AWS blockchain templates for Hyperledger Fabric also include the feature of launching a PostgreSQL server container for supporting Hyperledger Explorer. You can find a succinct outline of the components in an AWS Hyperledger Fabric blockchain template in the following diagram.

Stages of Deploying a Hyperledger Fabric AWS Blockchain Template

With a clear impression of the different components that are evident in an AWS Blockchain Template for Hyperledger Fabric, it is important to obtain a high-level perspective on creation of Hyperledger Fabric blockchain service on AWS. Here are some of the high-level steps that you must follow for creating a Hyperledger Fabric blockchain service on AWS. 

Step 1: The first step in deploying an AWS Hyperledger Fabric blockchain service is the selection of a blockchain framework. The common choices include Ethereum, Hyperledger Fabric, or Corda. For the case of this discussion, we shall select Hyperledger Fabric as the preferred blockchain framework for deployment. 

Step 2: The second stage of creating and deploying a Hyperledger Fabric blockchain service on AWS involves selection of the region on AWS for deployment. Users have the option for selecting the deployment of AWS blockchain template for Hyperledger Fabric in three public AWS regions. 

Step 3: Subsequently, the users depending on AWS blockchain templates to run Hyperledger Fabric blockchain applications should create a VPC. The Amazon Virtual Private Cloud service can provide adequate support in this case. 

Step 4: Now, you have to develop the key pairs and security groups according to the specifications of your application. 

Step 5: Users must also configure the CloudFormation stack for their blockchain application for running the application on cloud. 

Step 6: After finalizing the design of the template with all verified components, you can move ahead with the process of deploying the template. 

Step 7: In the final step, users can carry out tasks such as installation of smart contracts or chaincode to ensure desired functionality from the blockchain network.

Prerequisites for Deploying AWS Blockchain Template for Hyperledger Fabric

The high-level presentation of deploying a Hyperledger Fabric blockchain network on AWS shows the simplicity of using AWS blockchain templates. However, any AWS Hyperledger Fabric tutorial would focus prominently on the prerequisites. Users must pay attention to the following requirements when launching AWS blockchain template for Hyperledger Fabric applications.

  • First of all, users must ensure that the IAM principle, such as the user or group used by them, has the necessary permissions to work with related services. 
  • The next important prerequisite for using AWS Hyperledger Fabric blockchain template points out access to a key pair. The key pair in concern here refers to the one used for accessing EC2 instances, such as using SSH. It is also important to ensure that the key is available in the exact region where the instance is located. 
  • It is also important for users to have an EC2 instance profile featuring an attached permissions policy. The permissions policy can allow access of the Hyperledger Fabric network to Amazon Elastic Container Registry for pulling containers and Amazon S3. Users can view the official documentation on instances of IAM permissions for EC2 instance profile. 
  • The next important prerequisite for using AWS Blockchain Template for Hyperledger Fabric refers to the Amazon VPC network. The Amazon VPC network must feature a public subnet or a private subnet having an Elastic IP address along with a NAT Gateway for enabling easier access to AWS CloudFormation, Amazon ECR, and Amazon S3. 
  • The final and most important prerequisite for setting up AWS Hyperledger Fabric blockchain network is an EC2 security group. The security group must feature inbound rules for enabling SSH traffic at port 22 from different IP addresses which want to connect to the instance by using SSH. The security group is also essential for clients who have to connect with Hyperledger Explorer at port 8080.

Example of IAM Permissions for Selected EC2 Instance Profile

After a detailed overview of the prerequisites to deploy a Hyperledger Fabric blockchain network on AWS, it is important to understand the example IAM permissions. Users could set up specifications for an EC2 instance profile ARN to serve as a parameter in the use of AWS blockchain template for Hyperledger Fabric. The following example policy statement offered on official AWS website serves as a reference for creating the permissions policy related to a concerned EC2 role and instance profile.


    "Version": "2012-10-17",

    "Statement": [


            "Effect": "Allow",

            "Action": [












            "Resource": "*"




Connection with Hyperledger Fabric Resources

Users can easily connect with Hyperledger Fabric resources on a concerned EC2 instance after finding the ‘CREATE_COMPLETE’ message by the root stack created with the concerned template. This is one of the important aspects of an AWS Hyperledger Fabric tutorial as it plays a crucial role in achieving the comprehensive functionalities of Hyperledger Fabric blockchain on AWS. 

If users have a specified public subnet, then they could connect to the EC2 instance easily, just like any other common EC2 instance. On the other hand, if you have set up a private subnet, you can configure and deploy a bastion host on proxy connections to Hyperledger Fabric resources. 

It is also important to note that the AWS blockchain template for Hyperledger Fabric assigns a public IP address to the EC2 instance that hosts Hyperledger Fabric services. On the other hand, the IP address is not accessible to the public due to routing policies specified in the private subnet. The routing policies specified by users impose formidable limitations on movement of traffic between public sources and concerned IP address.

Using a Bastion Host for Proxy Connections 

In the final stage of the tutorial on getting started with AWS Hyperledger fabric blockchain, the main discussion would focus on proxy connections by leveraging a Bastion Host. As a matter of fact, Hyperledger Fabric services can experience setbacks in public availability. In such cases, users can easily leverage a bastion host for connecting to Hyperledger Fabric resources. The bastion host is basically an EC2 instance, and users have to focus on addressing certain important requirements before running. Here is an outline of the important requirements that you must follow while setting up a bastion host. 

The concerned EC2 instance for the specific bastion host must be vested in a public subnet featuring auto-assign public IP functionality alongside an internet gateway.

The bastion host must feature a key pair that enables supports for SSH connections.

The bastion host is related closely with a security group that has the capability to enable inbounded SSH traffic from clients connecting to the host.

Finally, the security group allocated for the Hyperledger Fabric hosts must support inbound traffic across all ports from sources in the VPC. The Hyperledger Fabric host could be the host EC2 instance in case of docker-local being the container platform or Application Load Balancer in case of ECS being the container platform.
