VXLAN Overview

As its name indicates, VXLAN is designed to provide the same Ethernet Layer 2 network services as VLAN does today, but with greater extensibility and flexibility. Compared to VLAN, VXLAN offers the following benefits:

   Flexible placement of multitenant segments throughout the data center: It provides a solution to extend Layer 2 segments over the underlying shared network infrastructure so that tenant workload can be placed across physical pods in the data center.
   Higher scalability to address more Layer 2 segments: VLANs use a 12-bit VLAN ID to address Layer 2 segments, which results in limiting scalability of only 4094 VLANs. VXLAN uses a 24-bit segment ID known as the VXLAN network identifier (VNID), which enables up to 16 million VXLAN segments to coexist in the same administrative domain.
   Better utilization of available network paths in the underlying infrastructure: VLAN uses the Spanning Tree Protocol for loop prevention, which ends up not using half of the network links in a network by blocking redundant paths. In contrast, VXLAN packets are transferred through the underlying network based on its Layer 3 header and can take complete advantage of Layer 3 routing, equal-cost multipath (ECMP) routing, and link aggregation protocols to use all available paths.

VMware Identity Manager (vIDM)

VMware Identity Manager can act as an identity platform or it can federate identity from other identity platforms such as ADFS, Okta or another SAML platforms. This is how it works:
  1. A user browses to the vRealize Automation home page
  2. The unauthenticated user is redirected to VMware Identity Manager which has been configured as identity management platform
  3. If the browser does not already have a session established with VMware Identity Manager the user is redirected the customer's identity platform
  4. The customer enters in their credentials into the 3rd Party identity platform
  5. A SAML assertion is generated by the identity platform and passed to vIDM
  6. VMware Identity Manager generates an OAuth2 token and passes it to vRealize Automation
  7. vRealize Automation validates the OAuth2 token and grants access
This provides organizations with a wide range of options for integrating vRealize Automation into their existing identity management system.

What is Azure AD ?

Microsoft Azure Active Directory (Azure AD) is a cloud-based identity and access management solution. Its primary purpose is to provide authentication and authorization when accessing cloud-based resources. However, you can also leverage its functionality to protect on-premises applications. In both cases, you can further streamline and enhance secure access to sensitive services and data by taking advantage of Azure AD’s single sign-on (SSO), federation, and Microsoft Azure Multi-Factor Authentication capabilities. 


Virtual hard disks typically use the .vhd extension. Windows Server 2012 introduces a new type of virtual hard disk that uses the .vhdx extension. Virtual hard disks with the .vhdx format have the following benefits over virtual hard disks that were used in Hyper-V on Windows Server 2008 and Windows Server 2008 R2:
  • Virtual hard disks with the .vhdx format can be as large as 64 terabyte (TB), whereas virtual hard disks with the .vhd format are limited to 2 TB.
  • Virtual hard disks with the .vhdx format are less likely to become corrupt if the virtualization server suffers an unexpected power outage.
  • The .vhdx format supports better alignment when deployed to a large sector disk.
  • Virtual hard disks with the .vhdx format can hold larger dynamic and differencing virtual hard disks. This provides for better performance from the dynamic and differencing virtual hard disks.
You can convert a virtual hard disk with the .vhd format to the .vhdx format by using the Edit Virtual Hard Disk Wizard. You might want to do this if you have upgraded a Windows Server 2008 or Windows Server 2008 R2 virtualization server to Windows Server 2012 or Windows Server 2012 R2. You can also convert a virtual hard disk with the .vhdx format to the .vhd format. 

What is Azure ?

Azure is the public cloud services offering from Microsoft. Microsoft datacenters deliver Azure services over the Internet. Customers can subscribe to a variety of the Azure services that run in these datacenters, typically at a cost lower than they might incur if they purchased or hosted their own hardware, or built their own services and software.

Individuals, customers, and Microsoft partners can use several methods to access Azure–based services. Partners have access to programs such as Microsoft Azure platform Cloud Essentials for Partners and Cloud Accelerate. Both customers and partners can access resources through MSDN and through the Microsoft BizSpark program, each of which provides a predefined amount of resources and services to build solutions.
