Blockchain on AWS: Pros, Cons & Alternative Solutions

Navigating AWS Blockchain: Benefits, Drawbacks & Other Options

Amazon Web Services (AWS) offers a suite of blockchain services that enable businesses to build scalable and secure blockchain networks with relative ease. The primary services in AWS's blockchain offerings are Amazon Managed Blockchain and Amazon Quantum Ledger Database (QLDB).

In this article, as sideline spectating stakeholders, and decentralization enthusiasts, we've outlined the pros and cons of many open-source & paid services. We'll also look at IBM's Blockchain Platform, Microsoft Azure Blockchain Service, Quorum & Corda.

Amazon Managed Blockchain:

Amazon Managed Blockchain is a fully managed service that allows you to create and manage scalable blockchain networks using popular open-source frameworks such as Hyperledger Fabric and Ethereum.


  • Fully managed service: Simplifies the process of creating and managing blockchain networks, enabling you to focus on your core business.
  • Scalability: Supports thousands of applications and millions of transactions, allowing your blockchain network to grow as your business expands.
  • Security: Built-in security features, including encryption at rest and transport and automatic detection and recovery from node failures.
  • Interoperability: Supports Hyperledger Fabric and Ethereum, enabling you to work with the blockchain framework of your choice.


  • Limited to supported frameworks: Only supports Hyperledger Fabric and Ethereum, which might not meet the requirements of businesses seeking to work with other blockchain frameworks.
  • Cost: Using Amazon Managed Blockchain comes with higher associated costs, which might price out smaller businesses.

Deciphering Blockchain

Amazon Quantum Ledger Database (QLDB):

Amazon QLDB is a fully managed ledger database that provides a transparent, immutable, and cryptographically verifiable transaction log.


  • High performance: Amazon QLDB can scale to handle millions of transactions, ensuring smooth performance even as your business grows.
  • Cryptographically verifiable: Offers a secure and tamper-proof transaction log, ensuring the integrity of your data.
  • Serverless: Eliminates the need for provisioning or managing servers, reducing operational overhead.
  • Integrates with AWS services: Easily integrates with other AWS services such as AWS Lambda, Amazon S3, and Amazon Kinesis.


  • Not a full-fledged blockchain solution: While Amazon QLDB offers a secure and verifiable ledger, it lacks some decentralized features of a complete blockchain solution.

Alternative Blockchain Solutions:

IBM Blockchain Platform:

IBM Blockchain Platform is a fully integrated, enterprise-ready blockchain platform that simplifies a multi-institution business network's development, governance, and operation.


  • Built on Hyperledger Fabric: Offers a secure, modular, and scalable platform for developing blockchain applications.
  • Extensive tooling and support: Provides a comprehensive set of tools and resources for building, deploying, and managing blockchain networks.
  • Integration with other IBM services: Seamless integration with IBM Cloud, Watson, and other IBM services.


  • Cost: IBM Blockchain Platform can be expensive, especially for smaller businesses or startups.
  • Limited to Hyperledger Fabric: It does not support other blockchain frameworks, which might be a constraint for companies looking for more flexibility.

Microsoft Azure Blockchain Service:

Microsoft Azure Blockchain Service is a fully managed ledger service that enables users to build, govern, and expand consortium blockchain networks.


  • Supports multiple blockchain frameworks: Offers support for Ethereum, Hyperledger Fabric, and Corda, providing flexibility in choosing the proper framework for your needs.
  • Integration with Azure services: Seamless integration with other Azure services and tools for monitoring, data management, and analytics.
  • High availability and scalability: Offers built-in high availability and the ability to scale as your business requirements grow.


  • Cost: Using Azure Blockchain Service comes with associated costs, which might concern smaller businesses or startups.
  • Limited to supported frameworks: While it supports multiple blockchain frameworks, it might not cater to companies looking to work with other, less common frameworks.


Quorum is an open-source, enterprise-focused version of Ethereum, designed specifically for permissioned networks and tailored to the financial services industry's needs.


  • Ethereum-based: Inherits the capabilities of Ethereum, making it easy for developers familiar with Ethereum to adopt Quorum.
  • Enhanced privacy features: Provides advanced privacy and security features, such as private transactions and smart contracts.
  • High throughput: Offers higher transaction throughput than public Ethereum, making it suitable for enterprise use cases.


  • Limited use cases: Primarily designed for the financial services industry, which may only be suitable for some businesses.
  • Less mature ecosystem: Compared to Ethereum, Quorum has a smaller developer community and fewer tools and resources available.


Corda is an open-source blockchain platform designed specifically for businesses, offering privacy, security, and interoperability features.


  • Business-focused: Designed to meet the specific needs of businesses, providing privacy, security, and scalability.
  • Interoperability: Enables seamless communication and data exchange between different Corda networks.
  • Support for various industries: Suitable for multiple industries, including finance, healthcare, supply chain, and more.


  • Learning curve: Corda's unique architecture and development model may require additional time and resources to learn and adopt.
  • Less mature ecosystem: Compared to Ethereum or Hyperledger Fabric, Corda has a smaller developer community and fewer tools and resources available.

Choosing the right blockchain solution for your business depends on your specific requirements, such as the desired level of decentralization, privacy, security, and scalability. It is essential to carefully evaluate the pros and cons of each platform and consider factors such as integration with existing systems, development resources, and long-term support. By thoroughly analyzing the options available, you can select a blockchain solution that best aligns with your business objectives and helps drive innovation and growth.
