  6. Explain scalability to stakeholders
    • Identify the use case (new development or transition of existing product or service)
    • Understand that rules can be set to adjust resources based on need
  7. Recommend off-the-shelf (OTS) or custom solutions as needed
    • Identify the use case (new development or transition of existing product or service)
    • Evaluate if existing OTS offering meets performance, availability, scalability, and reliability needs
    • Evaluate technical effort needed for custom solution
    • Evaluate if custom solution can exceed OTS on PASR criteria

Developing cloud architecture

  1. Choose between public, private, and hybrid cloud implementations
    • Identify the security and privacy requirements for the solution (focusing on networking options that each provides)
    • Consider limits imposed by tenancy in various cloud implementations
  2. Draw an architectural diagram (show data flows)
    • Break down the proposed solution into compute, data, and networking components
    • Produce logical groupings for the components
    • Mark data flows between components (including the protocol)
    • Identify system and component boundaries (including responsibility model)
  3. Define requirements
    • Decide whether to virtualize server, network, storage, and desktop
    • Be aware of design patterns like microservices and serverless
    • Consider networking infrastructure, storage devices, memory, and end-user devices required
  4. Identify how services communicate through application programming interfaces (APIs)
    • Identifying services with which the application needs to integrate
    • Interact using an API
  5. Create virtual machines               
    • Determine the operating system for the virtual machines
    • Choose the appropriate size for the virtual machines
    • Decide on geographic setting for the virtual machines (latency, legal requirements)
    • Configure options (e.g., time limitations, scaling, backups) for the virtual machines
  6. Identify data storage requirements                          
    • Distinguish between structured and unstructured data
    • Determine amount of storage needed
    • Consider location of storage
    • Consider storage security

Implementing the cloud development life cycle        

  1. Create content in virtual environments
    • Understand that a source-code management system needs to be set up
    • Install and configure the prerequisite packages in the virtual environment
    • Save changes and keep track of the codes in a source code management system (such as Github)
  2. Perform testing                                                                
    • Provide different test cases, test scenarios, and test scripts
    • Run the tests and report the bugs iteratively
  3. Structure the overall cloud-based solution
    • Integrate systems and applications within the selected environment
    • Integrate systems and applications with legacy systems
    • Integrate systems and applications with third-party applications
    • Distinguish between containers and virtual machines
    • Know when to choose containers over virtual machines
  4. Deploy application on server
    • Decide on the strategy to deploy a new application, replacing a previous one
    • Understand version control
    • Identify cloud-hosted solutions to create code and data pipelines (e.g., cloud-native CI/CD offerings and workflow automation like GitHub Actions)
    • Identify existing CI/CD practices

Managing cloud operations

  1. Manage operational costs
    • Understand usage-based pricing
    • Scale up and scale down to meet demand cost-effectively
  2. Develop business continuity and disaster recovery policy
    • Identify potential risks and disaster scenarios
    • Establish on-premise vs offsite backup strategy
  3. Provide support to users
    • Identify protection and security policies for external and internal users
    • Provide application and hardware support for internal users
    • Provide training tools for internal and external users
  4. Monitoring cloud systems
    • Log events
    • Monitor hardware and software (e.g., interpret graphs and dashboards)
    • Understand notifications or alerts for provisioning backup

Understanding cloud governance

  1. Comply with privacy and regulatory requirements
    • Identify relevant privacy requirements based on geographical and domain constraints (e.g. BIPA, HIPAA, PDP, FERPA, COPPA, GDPR, CCPA, etc.) as well as organization-specific policies
    • Identify cloud-provider compliance for these privacy regulations
    • Assess types of data managed within the environment
    • Assess location and storage of data
    • Be aware of NIST and ISO frameworks and standards
  2. Comply with ethical guidelines
    • Consider the impact of bias, lack of transparency, and lack of accountability
    • Explain potential bias and transparency challenges with prebuilt services
  3. Managing cloud security
    • Understand options and concepts for identity verification and authentication, including digital identity and multifactor authentication
