What is RPA Architecture? Explain It.

The architecture of Robotic Process Automation (RPA) is a combination of several tools, platforms, and various infrastructure elements to form a complete RPA tool.

There are several blocks available in the RPA solution:

• Applications under robotic process execution – This is well suited for enterprises applications like ERP, SAP or any other record processing application. These applications are data intensive and they are loaded with repetitive tasks.
• RPA Tool – To develop software robots to the automation of applications in Desktop, Web and Citrix environment. Exception handling, ability to write to/from various data sources and to build reusable components.
• RPA Platform – RPA Software bots can be stored in a shared repository and they can be shared across software robots libraries. RPA platform has the ability to develop meaningful insights on the bots and execution process.
• RPA Execution Infrastructure – They act as a bank of parallel physical or virtual lab machines which is controlled based on usage patterns. Machine scale up or down in parallel to achieve the automation can also be performed.
• Configuration management – Updation of bots to a newer version is performed. Branching and merging of RPA bots are also performed since they are reusable across the libraries.

RPA is a combination of various layers of application and tools that makes the whole architecture.

Layer	Purpose	Benefit
Process	Business rules Hand-off point Prioritization if not in management control	Focus on business rule without needing to create links Simplify changes
Subprocess	Reusable business logic  Identity Verification Reconciliation	Reusability Avoid multiple changes in the process when logic changes
Object	Procedures for performing specific tasks Eg. Log on, enter the address	Reusability within systems Development does not require business rule understanding
Component	Individual screen interaction Eg. Enter address inline 1	Lower risk, faster changes Target application integration can be changed without the risk of changing business rules.
