FUNDAMENTALS OF AZURE

• - Apponix Technologies

2

• Azure Network Connection Models
• Point-to-Site VPN
• It allows connections from individual computers
  to VMs on Azure network over Internet.
• It uses certificate authentication
• Upload root certificate to Azure
• Install client certificates on computers that
  will use Point-to-Site VPN client.
• Site-to-Site VPN
• It allows connecting on-premises network to
  Azure network.
• It requires configuration of on-premises routing
  device.
• The on-premises address space should not overlap
  Azure address space.

3

• ExpressRoute
• It enables dedicated, private, high-throughput
  network connectivity between on-premises network
  and Azure datacenter.
• The traffic does not travel over public Internet.
• Azure Traffic Manager
• Azure Traffic Manager controls the way traffic is
  distributed to different endpoints such as Azure
  Web Apps, Cloud Services, etc

4

• Azure traffic can be managed by below four
  routing methods using the Traffic Manager
• Geographic
• Weighted
• Priority
• Performance

5

• Traffic Manager gives below facilities
• It can be used to improvise the availability of
  important applications
• High performance applications can be made more
  responsive
• Without affecting the uptime you can do service
  maintenance
• Distribute traffic for large, complex deployments
• NetworkSecurity Group (NSG)
• NSG are used to control inbound and outbound
  traffic in Azure. It has rules which allow or
  block the traffic.
• NSGcan be linked to a subnet or individual
  network interfaces (NIC) attached to a VM.
• NSG evaluates lower priority rule first and the
  first rule that matches is the one that applies.

6

• Availability Set
• It distributes VMs across Fault Domains
  (physical) and Update Domains (logical) so that a
  fault or an update does not bring the VM down.
• Fault Domain (FD)
• It is a rack of servers.
• It has a single point of failure so if a rack
  fails (e.g. power supply issue) then all servers
  in that rack are affected.
• Resources should be spread across multiple fault
  domains.
• Update Domain (UD)
• Logical collection of servers that can be updated
  as a set at same time.
• By placing resources in separate Update Domains,
  they remain available during regular update
  processes.
