100% agree that performance should be the first while developing mobile web.
However, I kind of feel that the approach of reducing markup tags and limiting the JavaScript put us backdated. In nutshell, any restrictive approach may not be the … read the rest.
Software Architecture styles
- Component based architecture. – Example, JEE.
- Layered architecture. – Example, JEE.
- Pipe & filter (or pipeline) – Output of one feeds into another component. Buffering may be required in between. – Example, Analytics ETL, data pipeline.
- Data centric (or database

Software design principles
- KISS – Keep it simple and stupid.
- What You Produce, Others Will Consume
- Be Open to the Future
- Plan Ahead for Reuse
- Clean code minimize the risk of bugs being hidden
- Loose coupling
- High cohesion
- Design should allow local change.
Designing system topology (Physical Architecture)
Steps in coming up physical architecture.
- Identify key subsystems of the solution.
- Segregate the subsystems physically depending on the resource requirements.
- Using baseline size the hardware per node.
- Decide on the # of nodes (Factor in scale & HA).
- Decide
Leadership styles
