Traditional E-Commerce Application

Idea: We want to setup an ecommerce website where we sell electronics, mobile phones etc
Initial Decisions:
- Start with existing opensource ecommerce and start selling asap
- Evaluate all possible infrastructures.
Solutions:
- Find an ecommerce application which fits my purpose
  - Team is tilted towards nopCommerce

Understand Application Architecture
Made some os/software choices
Possible Infrastructural choices
- Buy Servers and run it in our organization (On-premises)
- Try cloud
- Try SaaS (nopCommerce supported hosting)
Managing Datacenters
- Networking
  - Switching
  - Routing
- Racks
- Servers
- Virtualization
From network perspective
- We have two servers
  - web: should be accesible from internet
  - db: should not be accessible from internet
- The above case poses a challenge in a on-premise environments as i need to design DMZs ( De militarized Zones)
Cloud in this case seems sensible as we can come up with Application, Quickly and securely as well
Cloud offers Platforms as a Service (PaaS) where we get databases directly and configuring backups is one-click
To run website we have two options
- IaaS:
  - We get ubuntu linux vm
  - installing all necessary softwares
  - maintaince (updates/patches) is our responsibility
- PaaS
  - We get .net platform
  - directly deploy nopCommerce
Summarize:
- We prefer cloud
- For mysql database we need a PaaS
- For nopComemrce web application we got with IaaS (virtual machines)
IaaS vs PaaS vs SaaS
