Azure Classroom Series – 07/Jul/2020

Basic Networks in your enterprise and cloud

• Single location Organization network
• Multi location Organization network
• In the above two cases your organization is owning the network configuration
• Now if we use the azure virtual infrastructure to run applications then new challenges are to resolved
• Public connectivity: Any application/server that can be directly connected using an public ip address/hostname/domain , Eg: swiggy, bookmyshow, facebook etc
• Private Connectivity: Any application/server that cannot be connect directly from internet, but expects you to be in particular network Eg: Office servers, internal applications etc
• Network monitoring: Monitor your network resources on the cloud
• Protection services: DDoS, Firewalls etc
• Networking componenets: Layer-4 Loadbalancers and Layer 7 loadbalancer, DNS

Scenario: LearningThoughts

• Organizational needs:
  • LearningThougts which has 3 major applications which are used by customers from internet.
  • LearningThoughts has lot of internal applications which are meant for usage only in office (on-premise)
  • LearningThoughts has two datacenters one in Hyderabad other in Bangalore
  • As of LT is running all of its infrastructure on Datacenters and now they want to leverage the azure cloud
• Team:
  • Datacenter Networking: This team is managing the Datacenter networks for LT
  • Architecture: This team is responsible for design of the applications
  • Administrator: This team is responsible for deploying the applications in the Datacenter
  • Project Teams: Thes project teams are responsible for delivering the assigned projects (Dev, test etc)
• Activity:
  • Learning thougts decided to go with azure cloud, initially they want to run the project (QTCommerce) on the azure cloud
  • The current infrastructure of QTCommerce is as shown below
• Way forward :
  • To do this job, we need to understand networking (public & private)
    • Ipaddressing and subnets
    • Regions
    • Software defined Networks
    • Virtual Networks
    • DNS
  • As a first step for doing this (proof of concept), you are asked to design the network infrastructure
