![]() External task manager extracting workflow state, job data, performing the task, and re-inserting the job data back into the databaseĪWS offers two workflow state management services: Amazon Simple Workflow Service (Amazon SWF) and AWS Step Functions. Each task is defined with a task input criterion, task action, task output, and task disposition, see Figure 1.įigure 3. Jobs are submitted to the workflow where tasks are initiated in the proper sequence to achieve consistent results. We’ll show how transitioning your workflow state management from a legacy database workflow to AWS services enables new capabilities with scale.Ī workflow system is composed of an ordered set of tasks. ![]() This blog describes how to use modernized workflow methods that will mitigate database scalability constraints. The complexity of modern workflows, frequency of runtime, and external dependencies encourages us to seek alternatives to using these database mechanisms. Add to this the responsibility of managing workflow states through custom triggers and job-based algorithms, which further exacerbate the performance constraints of the database. But this can present problems, such as inefficient use of data storage and compute resources, performance issues, and decreased agility. ![]() Enterprise organizations often use relational database management systems (RDBMS) to provide embedded workflow state management. The relational database is a critical resource in application architecture. Post Syndicated from Scott Wainner original
