Optimajet--Workflow Server

Workflow Server 

Stand-alone ready to deployed on-premises or in the cloud

 

Workflow Server is a ready-to-use Workflow Engine-based application with an administrator panel that you can deploy into your infrastructure. It can be integrated with NodeJS, PHP, Ruby, .NET, or Java applications via a REST API.

Workflow Server is a key component for managing the lifecycle of business objects within your enterprise. Workflow Server supports all the functions of Workflow Engine.

Performance

Workflow Server can process about 200 requests per second on a typical 4 GB RAM server. The response time of a single request is about 20 ms. Performance does not degrade with up to several million records with default database server settings. Custom database server settings are required for larger volumes of data. Performance can vary drastically depending on your schemes. We have prepared SoapUI tests so that you can test performance yourself. 

Capabilities

We tried to make Workflow Server as lightweight and simple as possible, yet, with a wide range of capabilities. Key capabilities of Workflow Server are:

· Workflow processing

· Determining a form by workflow state and current user role

· HTTP API integration

· Reports

Workflow features are:

· Workflow scheme versioning

· Changing the process scheme in real-time

· Inbox/outbox folders

· Process execution simulation

Architecture

Workflow Server is based on Workflow Engine and has an HTTP API, a dashboard for an administrator and a set of reports. The architecture of the product is depicted below. When developing Workflow Server, we were guided by the generally accepted rules of building program products.

 

Workflow Server module

#	Built-in module	Purpose
1	Workflow Engine	Responsible for workflow processing and has a graphic designer for workflow creation
2	Business process flow	Allows to determine the current workflow form depending on the state and user role
3	HTTP API	External API module for integration with other applications
4	Dashboard	UI for administrator. Allows to create and modify schemes and manage workflow processes
5	Reports	Statistic reports on schemes and performance

Workflow Server Integration scheme

Workflow Server has a set of 2 APIs for integration:

1. Workflow API - allows you to create processes and set their states.

2. CallBack API (WebHooks) - allows you to include additional actions and conditions to the workflow, and get notifications on workflow state changes

 

An example of integration of Workflow Server into a microservice architecture with and without an enterprise service bus is depicted below. Integration with enterprise service bus:

Power of Workflow Server

The foundational tool for business process management (BPM), Workflow Engine, enables automation of workflow design using low-code visual builders. It is built using JavaScript libraries and the.NET Framework/.NET Core.

 

Despite being a part of Workflow Server, Workflow Engine can be purchased separately. It enables workflow processing and proper integration by giving graphic designers the tools they need to construct process workflow schemes. This software component also makes workflow management, execution, and visualization easier.

Workflow Engine can resolve several tasks and issues related to process automation as described below:

· Parallel and hierarchical process resolution.

· Workload optimization.

· Business mission-critical process accomplishment.

· Process planning, implementation and follow up.

· In addition, Workflow Engine main functionalities can be implemented by creating C# objects which facilitates software integration. These objects are:

 

WorkflowRuntime - It provides an API for the Workflow Designer and enables process creation, document management, command execution, setting a process state and so on.

 

Workflow Engine compatibility

 

 

Workflow Designer component

Engine core component HTML 5 visual designer

Designer allows you to easily create interactive workflows of any complexity, there’s no need to draft them programmatically. We reated this native element to let you design, model, edit and visualize your custom workflows.

 

Workflow modeller features

Fully customizable

Drag and drop and configure the step properties

React, Angular, plain Javascript ready

Fully graphical web-based process designer

Many out-of-the-box steps (and growing)

WYSIWYE – What you see is, what you execute

Build and use your own custom steps

Build and use your own data types

Build and use your own business objects

Embed the designer in any application

Localization (RTL)

Stores workflow definitions as XML

Write your custom code C# in the Designer

Scheme inlining

 

Workflow Engine core component

Workflow Engine offers its users all the components necessary to implement workflows of any complexity; and helps them to maintain consistent business processes. Workflow Engine is designed to improve organizational efficiency and productivity, allowing companies to concentrate on job performance rather than workflow management.

 

ACTIVITIES

Define document statuses, sets of methods to be executed and other workflow activities.

 

TIMERS

Set an interval or date/time to trigger a transition from one activity to another.

 

ACTIONS

Connect activities with transitions that are triggered by commands or timers.

 

ACTORS

Add multiple actors with different roles, including users and external systems.

 

COMMANDS

Specify commands that should be executed to trigger a specific transition.

 

TRANSITIONS

Connect activities with transitions that are triggered by commands or timers.
