Amazon Simple Workflow - Cloud-Based Workflow Management
Simple Workflow — Today we are introducing the Amazon Simple Workflow service, SWF for short. This new service gives you the ability to build and run distributed, fault-tolerant applications that span multiple systems (cloud-based, on-premise, or both).
Context & Ripple Effects
AWS has been building out cloud primitives over several years, from grid storage and SimpleDB to EC2 load balancing, auto scaling and monitoring. Its 2011 Elastic Beanstalk launch also put deployment simplification higher in the stack.
SWF adds a coordination layer for applications whose work spans multiple systems, including on-premise infrastructure. That makes AWS's proposition less about supplying individual infrastructure components and more about managing how distributed application tasks are sequenced and recovered.
First-order effects
- Developers can use Amazon's managed service to coordinate fault-tolerant work across cloud and on-premise systems rather than building that workflow-management layer themselves.
- Amazon adds a workflow service alongside its existing infrastructure and deployment offerings, broadening the set of application operations it can host.
Second-order effects
- AWS customers can connect EC2 scaling and monitoring capabilities to longer-running application processes through a common managed workflow layer, making those services more useful together.
- Cloud providers focused on compute and storage face pressure to offer higher-level operational services as developers seek to reduce the integration work around distributed applications.
Third-order effects
- If AWS continues to package infrastructure operations into managed application services, cloud competition shifts toward the developer control plane that governs deployment, scaling, monitoring and workflow execution.
- Workflow ownership becomes a strategic layer: the provider coordinating application steps gains a deeper role in how customers design and operate distributed systems.
The trend: Cloud platforms are moving from discrete infrastructure building blocks toward managed control-plane services that orchestrate distributed application operations.
