Description
This unit describes the skills and knowledge required to design and implement fault tolerant and scalable workloads to achieve high availability in a cloud environment.The unit applies to cloud computing architects, cloud developers, cloud engineers and those engaged in designing and implementing cloud computing solutions for a business. It applies to individuals in Information Communications Technology (ICT) professions involved in systems design and systems architecture. No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Identify high-availability requirements
  • 1.1 Determine reliability, recoverability and service levels required for application
  • 1.2 Determine cloud infrastructure according to business needs
  • 1.3 Identify level of shared security responsibility models according to business needs
2. Evaluate architecture availability
  • 2.1 Review architecture of traditional multi-tier web application in non-cloud environment and identify high availability requirements
  • 2.2 Identify any single points of failure
  • 2.3 Estimate recovery objectives for multi-tier web components and for overall architecture
  • 2.4 Determine components that must scale vertically and the potential impact on system availability
  • 2.5 Document architecture review findings according to business needs
3. Design cloud-based architecture for high availability
  • 3.1 Design equivalent architecture for high availability using cloud services
  • 3.2 Identify and remove single points of failure as required
  • 3.3 Estimate recovery objectives for each component and overall architecture
  • 3.4 Determine components that must scale vertically and the potential impact on system availability
  • 3.5 Document architecture design according to business needs
4. Implement cloud-based architecture for high availability
  • 4.1 Implement architecture design in cloud environment
  • 4.2 Demonstrate connectivity between resources at all tiers
  • 4.3 Monitor and measure availability of resources
  • 4.4 Simulate failures of component and confirm that infrastructure is fault tolerant
  • 4.5 Simulate resizing components likely to impact performance and measure availability impact
  • 4.6 Compare and document simulation findings according to documented design
5. Finalise cloud infrastructure
  • 5.1 Adjust and improve availability of architecture according to simulations as required
