Using Amazon EC2 eliminates the need to invest in server hardware up front so that users can focus on, develop, and deploy applications faster. 
EC2 instances come in various hardware configurations and include an operating system.

Lambda Function in AWS AWS Lambda lets users run snippets of code without provisioning an infrastructure. 
This service is billed on a pay-as-you-go model, with users only paying for the execution time of their lambda code. 
There is no charge when code is not running. Lambda code can be set up to…

Three popular RPA tools functional differences

Robotic process automation is growing area and many IT developers across the board started up-skill in this popular area. I have written this post for the benefit of Software developers who are interested in RPA also called Robotic Process Automation.


In my previous post, I have described that total 12 tools are available in the market. Out of those 3 tools are most popular. Those are Automation anywhere, BluePrism and Uipath. Many programmers asked what are the differences between these tools. I have given differences of all these three RPA tools.
Automation

BluePrism

  • Blue Prism has taken a simple concept, replicating user activity on the desktop, and made it enterprise strength. 
  • The technology is scalable, secure, resilient, and flexible and is supported by a comprehensive methodology, operational framework and provided as packaged software.
  • The technology is developed and deployed within a “corridor of IT governance” and has sophisticated error handling and process modelling capabilities to ensure it can perform at scale within demanding, highly sophisticated operating environments.
  • The combination of SOA/BPMS and Blue Prism Robotic Automation platform provides almost total coverage of process automation opportunities
  • 'Object Studio' is the componet where you can develop script for business process automations
  • 'Process studio' is the component where you can test the objects that already developed in Object studio
  • Run and managing the process is monitored by 'Control Room'.
  • The data stored in this tool is SQL server
  • Architecture of BluePrism - Read for more details here.

Automation Anywhere

  • The RPA tool from automation anywhere is highly metured model and you can find lot of examples and material on this tool. The architecture comprises of Client, Bots and Control Room
  • Automation Anywhere is software designed to automate virtually any computer-based process with ease. 
  • No-programming-required interface makes it possible for anyone in an organization to quickly and reliably automate tasks of any complexity, including application integration, IT processes, data extraction and migration. 
  • It is available in Standard, Premier, Small Business, and Enterprise editions. 
  • The tool capabilities includes: Task to EXE, Job scheduler, Drag-and-drop task editor, Workflow and process mapping tools, Built-in Windows, web, and task recorders, Single-click web data extraction capabilities, and more.
  • The data will be stored in the tool called SQL express
  • The following five components present in Automation anywhere:
    • 1- IIS
    • 2- Framework Setup(AA)
    • 3- Sql Express/SQL 2014
    • 4- Control room setup
    • 5- Client installation

Uipath

  • Uipath comprises of three parts:
  • UiPath Studio– UiPath Studio is a highly intuitive visual processing modeling tool that helps you to design the process you intend to automate without any effort. The platform offers numerous best practices templates enabling users to have complete control over the automation.
  • UiPath Robots–UiPath Robots has front office and back office bots that execute the processes defined by you. While the front office robot shares the interface layer with the human agent who holds control over the utilization, the back office robot works in batch mode, without any intervention.
  • UiPath Orchestrator – UiPath Orchestrator allows you to deploy, start, stop, and schedule processes using a console and track the activities of robots. It offers a single interface to manage multiple robots that are running in your system.
  • The data will be stored in this tools is SQL server/Oracle
  • UiPath architecture diagram
