 # Azure Blockchain Workbench architecture
 
 Azure Blockchain Workbench simplifies blockchain application development by providing a solution using several Azure components. Blockchain Workbench can be deployed using a solution template in the Azure Marketplace. The template allows you to pick modules and components to deploy including blockchain stack, type of client application, and support for IoT integration. Once deployed, Blockchain Workbench provides access to a web app, iOS app, and Android app.

 Azure Blockchain Workbench simplifies consortium blockchain network setup as a preconfigured solution with an Azure Resource Manager solution template. The template provides simplified deployment that deploys all components needed to run a consortium. Today, Blockchain Workbench currently supports Ethereum.
 
-## Use Active Directory login
+## Use Active Directory
 
 With existing blockchain protocols, blockchain identities are represented as an address on the network. Azure Blockchain Workbench abstracts away the blockchain identity by associating it with an Active Directory identity, making it simpler to build enterprise applications with Active Directory identities.
 
 ## Synchronize on-chain data with off-chain storage
 
-Azure Blockchain Workbench makes it easier to analyze blockchain events and data by automatically synchronizing data on the blockchain to off-chain storage. Instead of extracting data directly from the blockchain, you can query off-chain database systems such as SQL Server. Blockchain specific expertise is not required for end users who are doing data analysis tasks.
