Cloud Computing and Network Security

Study Notes

A cloud can be described as a group of interconnected servers, located in one or more datacenters.
Public clouds also have some disadvantages, such as the lack of control over the underlay infrastructure used.
There are two main types of clouds: public and private. Private clouds are more expensive, but have more control over the underlay infrastructure.
Cloud deployment methods include: IaaS, CaaS, PaaS, FaaS, and SaaS.
Availability zones are a unique physical location within an Azure region, and each availability zone is made up of one or more data centers.
Azure hierarchy includes the tenant at the top, and a number of subscriptions beneath it. Each subscription contains a number of resource groups.
A cloud customer is responsible for securing the remaining elements of the cloud: network settings, applications, and data.
The Fortinet Security Fabric enables the following services and capabilities: native integration, broad protection, management and automation.
Azure includes a variety of network components, including a virtual network, subnet, network interface, Azure load balancer, VM scales set, virtual network gateway, and routing table.
You can connect VNETs to each other using Azure VNET peering or Azure VPN gateways.
Azure ARP processes manage all ARP traffic through a service that performs both switching and routing operations, depending on the destination address.
