Feature Specifications

  • put a summary or a brief description of the feature in question 
  • This feature is to support VPC on Hyper-V hypervisor. Currently VPC support is already available for Xen, VMware, KVM.
  • list what is deliberately not supported or what the feature will not offer - to clear any prospective ambiguities
  • list all open items or unresolved issues the developer is unable to decide about without further discussion
  • quality risks (test guidelines)
    • functional
    • non functional: performance, scalability, stability, overload scenarios, etc
    • corner cases and boundary conditions
    • negative usage scenarios
  • specify supportability characteristics:
    • what new logging (or at least the important one) is introduced
    • how to debug and troubleshoot
    • what are the audit events 
    • list JMX interfaces
    • graceful failure and recovery scenarios
    • possible fallback or work around route if feature does not work as expected, if those workarounds do exist ofcourse.
    • if feature depends other run-time environment related requirements, provide sanity check list for support people to run
  • explain configuration characteristics:
    • configuration parameters or files introduced/changed
    • branding parameters or files introduced/changed
    • highlight parameters for performance tweaking
    • highlight how installation/upgrade scenarios change
  • deployment requirements (fresh install vs. upgrade) if any
  • system requirements: memory, CPU, desk space, etc
  • interoperability and compatibility requirements:
    • OS
    • xenserver, hypervisors
    • storage, networks, other
  • list localization and internationalization specifications 
  • explain the impact and possible upgrade/migration solution introduced by the feature 
  • explain performance & scalability implications when feature is used from small scale to large scale
  • explain security specifications
    • list your evaluation of possible security attacks against the feature and the answers in your design* *
  • explain marketing specifications
  • explain levels or types of users communities of this feature (e.g. admin, user, etc)

Use cases

use cases listed in Inter-VLAN Routing 

Architecture and Design description

  • discussion of alternatives amongst design ideas, their resources/time tradeoffs and limitations. Explain why a certain design idea is chosen over others
  • highlight architectural patterns being used (queues, async/sync, state machines, etc)
  • talk about main algorithms used
  • explain what components are being changed and what the dependent components are
  • regarding database: talk about tables being added/modified
  • performance implications: what are the improvements or risks introduced to capacity, response time, resources usage and other relevant KPIs
  • preferably show class diagrams, sequence diagrams and state diagrams
  • if possible, publish signatures of all methods classes and interfaces implement, and the explain the object information of different classes
