Key Feature | Description |
|---|
Artifact Distribution Coordinator (ADC) | - ADC takes complete applications and breaks it into per-instance components that are then loaded into instances.
- ADC supports external Git and GitHub repositories.
|
Pluggable architecture support for adding new cartridges | - A cartridge is a package of code that includes a Virtual Machine (VM) image plus additional configuration, which can be plugged into Apache Stratos to offer a new PaaS service.
- If needed, a tenant can seamlessly add his or her own cartridges to Apache Stratos.
- Single tenant and multi-tenant cartridges are supported.
|
Support for cartridges | Support for PHP, Tomcat and MySQL cartridges. |
Elastic Load Balancer (ELB) with cartridge support | - Load monitoring
- Makes auto-scaling decisions.
- Receives load events from various places.
- Sends requests for load up or load down to the Cloud Controller.
- Accepts dynamic cluster domain registrations.
- Accepts static cluster domain registrations at start-up.
|
Multiple IaaS support | Currently, Apache Stratos has been fully tested on AWS EC2. However, it is very easy to extend Apache Stratos to support any IaaS that is supported by Apache jclouds. |
Policy based autoscaling into different IaaSes | - Used to automatically spawn instances.
- The current default implementation considers, the number of requests in-flight as the basis for making auto scaling decisions.
- In the default algorithm the paradigm “scale up early and scale down slowly” is followed.
|
Cloud Controller (CC) | CC leverages jclouds' APIs and provides a generic interface to communicate with different IaaSesIaaS. |
Topology Synchronization | The service topology is maintained in CC and shared across the Apache Stratos components both periodically and on change basis. |
Git based deployment synchronizer | Allows users to use their own Git repository to sync artifacts with a service instance. |
Stratos Controller UI | - Used by tenants to manage subscriptions.
- The Stratos Controller GUI can be used to carryout the following actions:
- Register a Tenant.
- View list of available cartridges.
- View list of subscribed cartridges.
- Subscribe to a cartridge.
- Unsubscribe from a cartridge.
- Connect to a data cartridge while subscribing to a cartridge.
- View subscribed cartridge detailed information.
- View list of auto-scaling policies available.
- Add domain mapping.
- Remove domain mapping.
- Synchronize repository.
- Monitor logs of cartridge instances in EC2.
|
Interactive CLI Tool | - Used by tenants to manage subscriptions.
- All the functions that can be carried out in the UI can be carried out via the CLI with the exception of tenant registering and monitoring logs of cartridge instances.
|
Custom domain mapping support | Tenants can add their own domain for a cartridge, using the domain mapping functionality. |
Usage metering and billing | Metering measures levels of resource utilization, while billing is the process where the cloud computing service subscribers are charged based on the metered data. |
