What limits your decision?

What limits your design or architectural decision?

• Resources are not unlimited!

• Find out the factor which limits or influence the decision and start from there when you are working on new requirement or design or concept.

• I want to buy the best and most expensive house but do I have that much money? In this case money is the limiting factor and I would start looking at the houses which fits in my budget.

• While selecting network device, you may be able to buy the higher capacity router but is your CO space can accommodate that?

• In case of Data Center, I can build higher BW Data Center with many servers/racks but do I have enough power/electricity(MW)?

• Weakest router in your design may restrict how big your OSPF/ISIS database can be!

• Worst link in your network path defines the data transfer speed!

• Best design is not the most technical and expensive design! Best design is the one which solves/meets the business requirements with a given resources.

• In short, identify the factor which is restricting you and start working with or around that to find optimal solution.

• Reduce complexity, increase simplicity:

  • Simple is easy to understand.
  • Simple is easy to explain.
  • Simple is easy to build.
  • Simple is easy to operate.
  • Simple is easy to recover.
  • Simple is easy to handover.
