No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
1. Design scalable web-application cloud infrastructure | 1.1 Determine and confirm cloud web-scaling needs 1.2 Review architecture for web application according to business needs 1.3 Identify cloud services required to scale web application 1.4 Design architecture changes using cloud services and check design scales network, compute and storage as utilisation increases 1.5 Determine architecture changes to scale for a global user base 1.6 Check availability and security of application is maintained with design changes and review design as required 1.7 Document and justify architecture changes |
2. Design scalable microservice architecture for a simple application | 2.1 Identify microservices and data transactions required to meet business needs 2.2 Determine cloud services to support microservice architecture 2.3 Design microservice architecture using cloud services 2.4 Document and justify architecture design |
3. Implement scalable microservice using cloud services | 3.1 Review microservice design and code components for application 3.2 Deploy and configure cloud services to implement the application 3.3 Test microservice components and confirm that the application is functioning 3.4 Troubleshooting and fix errors as required |
4. Finalise cloud infrastructure | 4.1 Set up metrics and trigger scaling alarms according to design specifications 4.2 Confirm, seek and respond to feedback with required personnel 4.3 Obtain final sign off from required personnel |
Evidence of Performance
The candidate must demonstrate the ability to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, and to:
