Design 101

Question 1

1) DETERMINE DESIGN FACTORS

Answer 1

· Requirements (functional and non-functional)
· Risks (potential danger to the environment)
· Assumptions (info is incomplete & filled in the gaps)
· Constraints (non-functional requirement)

· Satisfies the Requirements
· Minimise and mitigate the Risks
· Identifies the Assumptions
· Adhere to the Constraints

Question 2

2) CREATING A LOGICAL DESIGN WILL INCLUDE….

Answer 2

o       Compute
o       Storage
o       Networking
o       Security
o       Backup and availability
o       Management

· Look at these with a Holistic view – how will they affect each other?

Question 3

3) HOW TO GO ABOUT CREATING A PHYSICAL DESIGN

Answer 3

· Map the logical design to actual solutions with a physical design

· Specify actual products, models. Configurations, technologies and solutions

Question 4

What is the order to approach a Design Project

Answer 4

1) Determine Design Factors
2) Create a Logical Design
3) Create a Physical Design
4) Create a POC Design
5) Test design
6) Build Physical Design

Question 5

How to Map Solutions

Answer 5

· Select a solution
· Evaluating it against the design factors (requirements/risks, etc)
· Determining the affects areas
· Analysing for design impact

Question 6

4) BUILD AND TEST A POC SYSTEM

Answer 6

· Design must do what it is intended to do
· Meets the appropriates levels of availability
· Meets the appropriate levels of performance
· Supports the workloads
· Can it scale
· Satisfy the non/functional requirements

Is the design able to satisfy all the above? If not we need to modify the design where we have fallen short.

Question 7

5) DOCUMENT EVERYTHING

Answer 7

· Describe the design
· Create comprehensive design documents
· Visio Diagrams
· Results of testing – what/how done
· Operational guidelines
· Implementation guide – how everything is put together

Question 8

6) BUILD THE PHYSICAL PRODUCTION SYSTEM
