Answer #1

To understand the purpose of the Load Balanced Virtual Server Instances architecture, we observe the problem .

Problem : If a run time workload is improperly distributed across both virtual servers and their physical hosts, then some virtual servers become over-utilized, while others are under-utilized or running idle.

Solution :The workload is recalculated at run time and virtual servers are correspondingly moved between hosting physical servers to ensure even distribution across virtual and physical layers.

The related use of load balancing policies and the capacity watchdog monitor : A capacity watchdog surveys physical and virtual servers and reports variance to the VIM, which interacts with a load balancer and live VM migration to dynamically adjust virtual server locations.

List the cloud computing mechanisms associated with this architecture :

  • Automated Scaling Listener
  • Cloud Storage Device
  • Cloud Usage Monitor
  • Hypervisor
  • Live VM Migration
  • Load Balancer
  • Logical Network Perimeter
  • Resource Cluster
  • Resource Replication
  • Virtual CPU
  • Virtual Infrastructure Manager
  • Virtual RAM
  • Virtual Server
  • Virtual Switch
  • Virtualization Monitor

    The purpose of security policies is to help mitigate identified risks. Writing these policies is easier once you have created an asset inventory list, prioritized that list, and identified the major risk exposures found in those assets. The task of identifying your IT assets begins with recognizing that your IT infrastructure and supporting resources can be divided into the seven IT domains. The benefit of identifying the assets and prioritizing them across those domains is being able to document policies...
