Building Workflows with AWS Step Functions

AWS Step Functions use a state machine to represent the workflow. A workflow consists of a set of tasks, each of which represents a discrete activity to be performed. Each task is defined by a state of the state machine. In this article, we will learn about the main concepts of AWS Step Functions and apply those to build a workflow for a sample business process: Order Fulfillment.

The Implication of Feedback Loops for Value Streams

Lead time and throughput are dynamic variables which impact flow in a value stream. Capacity, processing time and feedback loops (such as error conditions) have a significant impact on WIP and flow and need to be mapped and measured when building value stream maps.

How Development Teams Can Orchestrate Their Workflow with Pipelines as Code

Infrastructure as Code was just the beginning. Configuration as Code followed shortly after – again becoming extremely commonplace and enabling organisations to scale their engineering capacity by a number of times. And in order to continuously increase the value development teams generate, Pipelines as Code is the natural consequence.

Ballerina Tutorial: A Programming Language for Integration

Ballerina is a new programming language and platform whose objective is to make it easy to create resilient services that integrate and orchestrate across distributed endpoints. Ballerina’s design principles focus on baking integration concepts into a language, including a network-aware type system, sequence diagrammatic syntax, concurrency workers, being “DevOps ready”, and environment awareness.

Ballerina Microservices Programming Language: Introducing the Latest Release and "Ballerina Central"

The tutorial demonstrates Ballerina, a new programming language and platform whose objective is to make it easy to create resilient services that integrate and orchestrate across distributed endpoints. Ballerina uses compile time abstractions for distributed system primitives that enable the compiler to generate artifacts like API gateways for deployment to Docker and Kubernetes.

Events, Flows and Long-Running Services: A Modern Approach to Workflow Automation

Recent discussions around the microservice architectural style has promoted the idea that “to effectively decouple your services you have to create an event-driven-architecture”. Although events can decrease coupling, we must avoid the mistakes of traditional SOA: centralised control should to be avoided, and workflow engines must be less painful to use and operate.

Purpose Case Management

Article “Purpose Case Management” describes a Case Management method that overarches BPM and Adaptive Case Management. Author reviews several modern movements such as Unstructured BPM, Social BPM, Dynamic BPM, and ACM. The article concludes with a generic method that allows switching between BPM and ACM depending on which one of them is more efficient in an execution context at certain moment.
