The logical network perimeter establishes a virtual network boundary that can encompass and isolate a group of related cloud-based IT resources that may be physically distributed. It is defined as the isolation of a network environment from the rest of a communications network.
Figure 7.4 depicts the logical network perimeter implemented at each DTGOV data center, as follows: • The routers that connect to the Internet and extranet are networked to external firewalls, which provide network control and protection to the furthest external network boundaries using virtual networks that logically …
The cloud storage device mechanism represents storage devices that are designed specifically for cloud-based provisioning. Instances of these devices can be virtualized, similar to how physical servers can spawn virtual server images.
Virtual networking enables communication between multiple computers, virtual machines (VMs), virtual servers, or other devices across different office and data center locations.
The automated scaling listener mechanism is a service agent that helps in monitoring and tracking communications between users and cloud services being accessed in order to achieve dynamic scaling.
Cloud monitoring is a method of reviewing, observing, and managing the operational workflow in a cloud-based IT infrastructure. Manual or automated management techniques confirm the availability and performance of websites, servers, applications, and other cloud infrastructure.
Defined as the isolation of a network environment from the rest of a communications network, the logical network perimeter establishes a virtual network boundary that can encompass and isolate a group of related cloud-based IT resources that may be physically distributed.
Cloud computing depends upon high-bandwidth connectivity to transmit data, so cloud infrastructure also includes typical equipment for local area networks, such as switches and routers, as well as virtual networking support and load balancing to distribute network traffic.
Cloud infrastructure is a term used to describe the components needed for cloud computing, which includes hardware, abstracted resources, storage, and network resources. Think of cloud infrastructure as the tools needed to build a cloud.
A VNET is the address space. It hosts subnet, where you will connect resources. Subnet segment the address space into multiple subnetworks. By default, an IP in a subnet can communicate with any other IP inside the VNET.
Virtual network and subnets. A subnet is a range of IP addresses in the virtual network. You can divide a virtual network into multiple subnets for organization and security. Each NIC in a VM is connected to one subnet in one virtual network.
VLAN. A virtual LAN network, or VLAN, uses partitions to group devices on a LAN network into domains with resources and configurations that are applied to each. Using a VLAN allows for better security, monitoring, and management of the devices and servers within a specific domain.
