Super metrics

• Health describes the current behavior of the environment and any problems that need to be addressed immediately. Health is composed of workload, anomalies and faults.  Workload is a measure of how hard the VM is working relative to the resources it wants and what it is entitled to using. Anomalies is an expression of the number of metrics trending above or below normal which is a leading indicator of upcoming performance problems, and faults is the number of “hard” thresholds that have been crossed when there is an availability issue or a hardware failure has occurred.
• Risk describes the potential for future problems. Risk combines scores for time and capacity remaining before resources are exhausted. Risk also includes a new metric for stress which shows patterns of chronic strain. For example, during certain times of the week, there is more demand for resources in one cluster while other clusters are at or below capacity. You can use this information to optimize VM placement or to pre-allocated resources ahead of time.
• Efficiency is a new super metric to describe optimal utilization of resources. Efficiency includes scores of reclaimable waste, such as idle, over- and under-provisioned VMs, and VM density.  VM density shows current consolidation ratio vs maximum possible ratio without performance degradation.

VMware View Pod

A VMware View pod integrates five 2,000-user building blocks into a View Manager installation that you can manage as one entity.

A pod is a unit of organization determined by VMware View scalability limits.

Pod Diagram for 10,000 View Desktops shows how all the components can be integrated into one manageable entity.

  

The network core load balances incoming requests across View Connection Server instances. Support for a redundancy and failover mechanism, usually at the network level, prevents the load balancer from becoming a single point of failure. For example, the Virtual Router Redundancy Protocol (VRRP) communicates with the load balancer to add redundancy and failover capability.

If a View Connection Server instance fails or becomes unresponsive during an active session, users do not lose data. Desktop states are preserved in the virtual machine desktop so that users can connect to a different View Connection Server instance and their desktop session resumes from where it was when the failure occurred.

vCloud Networking and Security

VMware vCloud® Networking and Security™ provides basic networking and security functionality for virtualized compute environments, built using the VMware vCloud® Suite.

It provides a broad range of services delivered through virtual appliances, such as a virtual firewall, virtual private network (VPN), load balancing, NAT, DHCP and VXLAN-extended networks. With vCloud Networking and Security, enterprises can virtualize business critical applications with confidence, secure VMware® Horizon View™ deployments and build secure and agile vCloud Suite based private clouds.

vCloud Networking and Security virtual-appliance 

The Edge Gateway appliance establishes a perimeter gateway for network traffic to enter and leave a virtual data center. It provides a wide range of services, including a highly available stateful inspection firewall, IPsec site-to-site VPN, a server-load balancer, NAT, and network services such as static routing, DHCP and domain name system (DNS). 

A second type of virtual appliance, App Firewall, provides protection directly in front of one or more specific workloads (e.g., virtual machines).

Firewall
Stateful inspection firewall that can be applied either at the perimeter of the virtual data center or at the virtual network interface card (vNIC) level directly in front of specific workloads.

VPN
Industry-standard IPsec and SSL VPN capabilities that securely extend the virtual data center. Site-to-site VPN support links virtual data centers and enables hybrid cloud computing at low cost.

Load balancer
A virtual-appliance–based load balancer to scale application delivery without the need for dedicated hardware. Placed at the edge of the virtual data center, the 
load balancer supports Web-, SSL- and TCP-based scale-out for high-volume applications.

NAT

vCloud Networking and Security Edge incorporates a flexible NAT engine that can map network and port addresses using a familiar configuration model. Administrators can deploy protected zones, also known as “demilitarized zones” (DMZs), without needing to manually change addresses for servers and applications. Application-layer gateways for common protocols enable applications to function in NAT environments.

Virtual extensible LAN (VXLAN): is a network encapsulation mechanism that enables virtual machines to be deployed on any physical host, regardless of the host’s network configuration. It solves the problems of mobility and scalability in two ways:

It uses MAC in UDP encapsulation, which allows the virtual machine to communicate using an overlay network that spans across multiple physical networks. It decouples the virtual machine from the underlying network thereby allowing the virtual machine to move across the network without reconfiguring the network.

VXLAN uses a 24-bit identifier, which means that a single network can support up to 16 million LAN segments. This number is much higher than the 4,094 (limit imposed by the IEEE 802.1Q VLAN specification.

Provider vDC

A Provider vDC is a collection of compute, memory, and storage resources from one vCenter. A Provider vDC provides resources to organization vDCs.

A Provider vDC is represented as a VMWProviderVdc element in the extension view and a ProviderVdc element in the admin view. A system administrator can create a VMWProviderVdc or modify it to add or remove datastores, storage profiles, and resource pools, or change other properties such as its description. A system administrator cannot change the primary resource pool or vCenter server that was specified when the Provider vDC was created.

Prerequisites

Verify that you are logged in to the vCloud API as a system administrator

Choose a vCenter server to supply a resource pool and storage profiles to this Provider vDC

Organization vDC

An organization vDC is to allocate resources to an organization. An organization vDC is partitioned from a provider vDC. A single organization can have multiple organization vDCs.

Prerequisites

You must have a provider vDC before you can allocate resources to an organization.

VMware vCloud Hybrid Service

VMware vCloud Hybrid Service is available in two service options, giving you the flexibility and scalability you need to meet your organization’s requirements.

A dedicated cloud provides you with a physically isolated infrastructure, giving you your own private cloud instance and the most control over your resources.

A virtual private cloud provides you with logically isolated infrastructure, with fully private networking and resource pools.

vShield

VMware vShield is a suite of security virtual appliances built for VMware vCenter Server integration. vShield is a critical security component for protecting virtualized datacenters from attacks and misuse helping you achieve your compliance-mandated goals.

vShield includes virtual appliances and services essential for protecting virtual machines. vShield can be configured through a web-based user interface, a vSphere Client plug-in, a command line interface (CLI), and REST API.

vCenter Server includes vShield Manager. The following vShield packages each require a license:

·         vShield Manager

·         vShield App

·         vShield Edge

·         vShield Endpoint

·         vShield Data Security

One vShield Manager manages multiple vShield App, vShield Edge, vShield Endpoint, and vShield Data Security instances.

vShield Manager

The vShield Manager is the centralized network management component of vShield, and is installed as a virtual appliance on any ESX™ host in your vCenter Server environment. A vShield Manager can run on a different ESX host from your vShield agents.

Using the vShield Manager user interface or vSphere Client plug-in, administrators install, configure, and maintain vShield components. The vShield Manager user interface leverages the VMware Infrastructure SDK to display a copy of the vSphere Client inventory panel, and includes the Hosts & Clusters and Networks views

Failure Impact

Infrastructure availability yes, service availability no. vShield Edge devices will continue to run without the management control, but no addition edge appliances or modifications to existing can occur until the service comes back online

vShield App

vShield App is a hypervisor-based firewall that protects applications in the virtual datacenter from network based attacks. Organizations gain visibility and control over network communications between virtual machines. You can create access control policies based on logical constructs such as VMware vCenter containers and vShield security groups—not just physical constructs such as IP addresses. In addition, flexible IP addressing offers the ability to use the same IP address in multiple tenant zones to simplify provisioning

The Flow Monitoring feature displays network activity between virtual machines at the application protocol level. You can use this information to audit network traffic, define and refine firewall policies, and identify botnets.

vShield Edge

vShield Edge appliances are self-contained environments that are stateless in nature. There is a “health check” API call you can make to a vShield Edge appliance to determine if it is functioning correctly. If the API returns negative, then you should initiate a reboot of the vShield Edge device. At the time of reboot, configuration information will be updated from the vShield Manager and the vShield Edge device will continue to function properly.

vShield Endpoint

vShield Endpoint offloads antivirus and anti-malware agent processing to a dedicated secure virtual appliance delivered by VMware partners. Since the secure virtual appliance (unlike a guest virtual machine) doesn't go offline, it can continuously update antivirus signatures thereby giving uninterrupted protection to the virtual machines on the host. Also, new virtual machines (or existing virtual machines that went offline) are immediately protected with the most current antivirus signatures when they come online.

vShield Endpoint installs as a hypervisor module and security virtual appliance from a third-party antivirus vendor (VMware partners) on an ESX host. The hypervisor scans guest virtual machines from the outside, removing the need for agents in every virtual machine. This makes vShield Endpoint efficient in avoiding resource bottlenecks while optimizing memory use.

vShield Data Security

vShield Data Security provides visibility into sensitive data stored within your organization's virtualized and cloud environments. Based on the violations reported by vShield Data Security, you can ensure that sensitive data is adequately protected and assess compliance with regulations around the world.

vShield Zones

Verify that you are logged in to the vCloud API as a system administrator.

VMware vShield Zones is a security virtual appliance that provides visibility and enforcement of network activity within a VMware vSphere™ deployment to comply with corporate security policies and industry regulations such as PCI or Sarbanes-Oxley.

Central Management of Logical Zone Boundaries and Segmentation

• Leverage existing virtual infrastructure containers hosts, virtual switches, VLANs as logical trust or organizational zones

• Define policies to bridge, firewall, or isolate network traffic between zone boundaries

• Manage and deploy policies across entire VMware vCenter Server deployment

• Integrate with VMware vCenter Server and automatically deploy on existing virtual networks

• Scan and discover existing applications running on virtual machines to identify application protocols

Network Enforcement and Flow Monitoring

• Classify traffic by network or application protocol (e.g. HTTP, RDP, and SNMP)

• Performantly filter traffic with stateful packet inspection (SPI)

• Track dynamic port connections for protocols such as FTP

• Track network connections across VMware VMotion migration events.

• Easily convert observed network flows into precise network enforcement rules.

• Monitor both allowed and disallowed activity

Management and Reporting

• Access the Web-based vShield Manager interface remotely from any Web browser

• Configure administrators to be common with VMware vCenter Server or distinct for separation of duties and roles

• View activity hierarchically at individual virtual machine or aggregate levels and generate graphical or tabular reports

• Retain log data for archival and compliance purposes

• Export events and data using syslog format

vCloud Organizations

A vCloud contains one or more organizations. Each organization represents a collection of end consumers, groups, and computing resources.

Users authenticate at the organization level, using credentials established by an organization administrator locally within vCloud Director or LDAP.

Administrative Organization

A vCloud requires at least one organization. As a best practice, the first organization to be created should be an administrative organization.

Administrative organization will own a master catalog of vApp templates that are published and shared with all other (standard) organizations.

Make sure that when you create the administrative organization you set it up to allow publishing of catalogs.

Standard Organizations

Create an organization for each tenant of the vCloud as necessary. Each of the standard organizations should be created with the following considerations:

•          Cannot publish global catalogs

•          Use system defaults for SMTP

•          Use system defaults for notification settings

•          Use leases, quotas, and limits meeting the provider’s requirements
