Cost Overview

vRealize Operations Cloud supports costing for private clouds, public clouds, and VMware Cloud infrastructure.

You can track expenses for a single virtual machine, and identify how these expenses attribute to the overall cost associated with your private cloud accounts and VMware Cloud infrastructure accounts.

On the  Cost Overview  home page in vRealize Operations Cloud, you can find details about the costs associated with your VMware Cloud infrastructure accounts, public cloud accounts, and your private cloud accounts.

You can view the Total Cost of Ownership, Potential Savings, and Realized Savings for your VMware Cloud infrastructure cloud accounts and vSphere private cloud accounts, and Total Cost of Ownership for your private cloud accounts.

This role is designed to give administrators access to manage virtual machines, networks, and other settings within the folder. The CloudAdmin role will also give the junior administrators access to all global permissions that are associated with the Development folder.

" The CloudAdmin role is designed to give administrators access to manage a single folder. This role grants access to manage virtual machines, networks, and other settings within the folder. Additionally, this role grants access to all global permissions that are associated with the folder. For example, if the folder has global permissions that allow users to create or delete virtual machines, the CloudAdmin role will grant access to those permissions within the folder. "

The CloudAdmin user can grant other users or groups read-only access to VMware Cloud on AWS vCenter management objects such as the Mgmt-ResourcePool, Management VMs folder, Discovered Virtual Machines folder, vmc-hostswitch, and vsanDatastore. Because this read-only access does not propagate to management objects, you cannot grant it as a Global Permission and instead must explicitly grant it for each management object. VMware Cloud on AWS runs a script once a day that updates any newly-created management o bjects (such as objects in a new cluster) so that the CloudAdmin user and CloudAdminGroup SSO group have the updated role applied. The script itself does not grant additional access to any user or group, so you ' ll need to wait until it completes before the CloudAdmin can use this workflow to grant read-only access to those objects.

A private network segment is an isolated network segment that is used for disaster recovery testing. Private network segments provide a secure and isolated environment for testing, allowing administrators to test their disaster recovery plans without risking the stability of their production environment. Private network segments also provide additional security, as they are not connected to the public internet, making them less vulnerable to external attacks. [1]

A valid management network CIDR based on the requirements is 10.1.0.0/20, as this provides a range of 4096 IP addresses, which is more than enough for 30 hosts. A /23 CIDR only provides 512 IP addresses, which is not enough for 30 hosts, while a /24 CIDR provides 256 IP addresses and a /16 CIDR provides 65,536 IP addresses, which is more than is needed for the 30 hosts.

" The VMware HCX on-premises deployment requires five IP addresses: two for the WAN appliance, two for the vMotion feature, and one for the management network. "  

In this scenario, the cloud administrator is utilizing the vMotion feature of VMware HCX to migrate several dozen workloads from an on-premises location to a VMware public cloud. They are also stretching three networks for the migration. When using vMotion, two IP addresses will be needed per vMotioned virtual machine: one for the source and one for the target. For the migration of several dozen workloads, this will require several dozens of IP addresses. Additionally, the administrator is also utilizing the capabilities of the WAN appliance to optimize migration traffic. In order to optimize the traffic, one IP address will be needed for the WAN appliance on the on-premises site, and another IP address will be needed for the WAN appliance on the public cloud side. Therefore, the total number of IP addresses that need to be reserved for the on-premises deployment of VMware HCX is the number of IP addresses required for the virtual machines plus one IP address for the WAN appliance on the on-premises site plus another IP address for the WAN appliance on the public cloud side, which totals to five IP addresses.

Operational isolation (operational “air-gapping”) is critical to DR. VMware Cloud DR was designed from the very beginning for its systems and repository to be operationally isolated and for instantiating isolated recovery environments.

IPFIX  (Internet Protocol Flow Information Export) is a standard for the format and export of network flow information for troubleshooting, auditing, or collecting analytics information. Port mirroring lets you replicate and redirect all of the traffic coming from a source. The mirrored traffic is sent encapsulated within a Generic Routing Encapsulation (GRE) tunnel to a collector so that all of the original packet information is preserved while traversing the network to a remote destination.

Use  Traceflow  to inspect the path of a packet. Traceflow traces the transport node-level path of a packet. The trace packet traverses the logical switch overlay, but is not visible to interfaces attached to the logical switch. In other words, no packet is actually delivered to the test packet’s intended recipients.

vRealize Log Insight  is a log collection and analytics virtual appliance that enables administrators to collect, view, manage and analyze syslog data. Log Insight provides real-time monitoring of application logs, network traces, configuration files, messages and performance data.

The three types of gateways that can be found in VMware Cloud on AWS are Option A: Distributed Tier-1, Option B: Standard Tier-1, and Option D: Compute Tier-1.

Distributed Tier-1 gateways are used for secure access between on-premises networks and the VMware Cloud on AWS SDDC network. Standard Tier-1 gateways are used for secure access between the VMware Cloud on AWS SDDC network and the public internet. Compute Tier-1 gateways are used for secure access between the workloads running on the VMware Cloud on AWS SDDC and the public internet.

For more information, please refer to the official VMware documentation on VMware Cloud on AWS Gateways: https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws.networking/GUID-1F2D1BFC-F5C7-4534-8B49-39F9D08E7F1A.html

The prerequisite step to adding additional users to a Google Cloud VMware Engine ' s vCenter (GCVE) is to add a user in Google Cloud Platform Identity and Access Management. This will allow for the user to be added to the vCenter and properly authenticated. To add additional users to a GCVE vCenter, a prerequisite step is to add a user in Google Cloud Platform Identity and Access Management (IAM) 1 .  This is because GCVE uses Google Cloud IAM to manage access to the private cloud 2 .  The user must have the appropriate IAM role, such as VMware Engine Admin or VMware Engine Viewer, to access the GCVE portal and vCenter 2 .  The user must also have a Google account or a Cloud Identity account 2 .  After adding a user in Google Cloud IAM, the user can sign in to the GCVE portal and launch the vCenter web console 2 .  The user can then perform operations based on the assigned vCenter role and group 3 .  References :  1 : Adding users to Google Cloud VMware Engine,  2 : Managing access to Google Cloud VMware Engine,  3 : Private cloud vSphere permission model

The two use cases that apply to NSX logical routing are A. You must provide external connectivity to VMs and containers, and B. Your organization must provide connectivity between VMs and containers that are connected to different segments. NSX logical routing allows you to provide external connectivity to VMs and containers, and to provide layer 3 connectivity between VMs and containers that are connected to different segments. It does not provide layer 2 connectivity between VMs and microservices or intrinsic security for VMs connected to different segments.

Example B illustrates the benefit of cloud computing where an organization can manage its cloud resources by using different cloud providers that are separate and isolated from each other. This allows the organization to make use of features and services offered by different cloud providers in order to benefit from the best of different services.

Example C illustrates the benefit of cloud computing where a business can store infrequently accessed data in the cloud in order to benefit from reduced on-premises storage costs, as cloud storage is usually cheaper than on-premise storage.

Example E illustrates the benefit of cloud computing where a developer can code an application in a cloud-based environment, and, with a few simple commands, deploy the application on the business website. This eliminates the need for the developer to set up and manage the application on their own, as the cloud platform handles the deployment and hosting of the application.

Example F illustrates the benefit of cloud computing where a large amount of storage can be made available in seconds using a cloud option. This is useful for businesses that require a large amount of storage but don ' t have the resources to set up and manage their own storage solution.

For more information on the benefits of cloud computing, see the VMware official documentation at https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws.getting-started/GUID-F0A2F338-A6A7-49AD-B158-CFFCA2F29C1B.html.

The statement that most accurately describes the service features of VMware Cloud on Dell EMC is C. An SDDC includes a minimum of one rack with three hosts. You can add hosts to the rack, up to the maximum supported by the rack. An SDDC consists of a rack with a minimum of three hosts, which can then be expanded up to the maximum supported by the rack. VMware Site Recovery is not included as part of the initial service offering.

VMware Cloud on Dell EMC provides a service that enables customers to run their VMware-based workloads on Dell EMC ' s hardware, in a jointly-engineered and fully-supported environment. The service allows customers to deploy a fully-configured VMware SDDC on Dell EMC VxRail or VxRack SDDC systems, with the option to add more hosts to the rack as needed.

A VMware Cloud software-defined data center (SDDC) uses a logical switching component called a Network Virtual Distributed Switch (N-VDS) or vSphere Distributed Switch (VDS) to provide layer 2 forwarding functionality  [1] [2] . A VDS is a network switch that provides centralized network configuration, management, and monitoring. It works with the NSX for vSphere data plane to provide layer 2 forwarding, packet filtering, and traffic monitoring services. A VDS is composed of multiple Segment Ports (which are like individual physical ports on a normal switch), Uplinks, and Transport Nodes. The Segment Ports are used to connect virtual machines to the VDS, while Uplinks are used to connect the VDS to physical networks. Transport Nodes are the physical switches that are associated with the VDS. For more information, see the official VMware documentation here:  https://docs.vmware.com/en/VMware-NSX-Data-Center/2.4/nsx_24_sdn_networking/GUID-A4A6E4A8-FD7C-4B6E-A3D3-6F9B6D0578C2.html.

VMware Cloud Disaster Recovery is a managed disaster recovery-as-a-service offering that is built on the latest version of VMware vSphere 7.0.

VMware vSAN is a distributed storage platform that is integrated into the VMware Cloud software-defined data center (SDDC). It provides policy-based storage management, allowing cloud administrators to define storage policies that can be applied to virtual machines and other workloads. These policies govern how data is stored, replicated, and secured, and are used to ensure that data is stored in a consistent and compliant manner.

https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vsphere.vmc-aws-manage-data-center-vms.doc/GUID-EDBB551B-51B0-421B-9C44-6ECB66ED660B.html

Kubernetes is an open-source container orchestration system for automating application deployment, scaling, and management, which provides features such as self-healing, auto-scaling, and service discovery. With Kubernetes, cloud administrators are able to easily scale and manage containers across multiple clusters and nodes, allowing them to more effectively manage container-based applications. Additionally, Kubernetes provides advanced features such as container scheduling, resource management, and servic e discovery, which are all essential for managing container-based applications in a production environment. For more information on Kubernetes, you can refer to the official VMware documentation  here . or is encount

To address a non-compliant object, such as an ISO image, a cloud administrator can apply a new VM storage policy directly to that object. This doesn ' t require modifying the default VM storage policy or recreating the ISO image. Applying a new policy to the ISO allows for specific storage requirements to be met without affecting other objects or the default settings.

Hybrid Linked Mode allows you to link your cloud vCenter Server instance with an on-premises vCenter Single Sign-On domain. https://docs.vmware.com/en/VMware-Cloud- on-AWS/services/com.vmware.vsphere.vmc-aws-manage-data-center-vms.doc/GUID-91C57891-4D61-4F4C-B580-74F3000B831D.html

Hybrid Linked Mode is the solution that meets the requirement of viewing and managing workloads across both an on-premises environment and a VMware Cloud on AWS SDDC.  Hybrid Linked Mode allows customers to link their on-premises vCenter Server with their VMware Cloud on AWS vCenter Server and use a single interface to manage both environments 1 .  Hybrid Linked Mode also enables customers to perform cold and live migrations of workloads between on-premises and cloud SDDCs 2 .  Hybrid Linked Mode leverages the existing vCenter Single Sign-On domain and does not require any additional components or licenses 1 .  References :  1 : Hybrid Linked Mode - VMware Docs,  2 : VMware Cloud on AWS Documentation

AWS Direct Connect is a service that establishes a dedicated network connection between an on-premises data center and an AWS region.  This can improve network performance, reduce costs, and increase security for applications that require high bandwidth and low latency 1 .

A layer 2 VPN connection would not improve performance as it still relies on the public internet. VMware HCX is a service that simplifies workload migration and mobility between different clouds, but it does not address network performance issues.  Contacting VMware support to request more bandwidth for IPSec VPN connection is unlikely to be effective as IPSec VPN has inherent limitations such as encryption overhead and packet fragmentation

By default, the management gateway firewall is set to deny all traffic between the internet and vCenter Server. Verify that the appropriate firewall rules are in place.

The administrator can create an NSX firewall rule in the VMware Cloud data center that allows access to the vCenter from the on-premises data center. This would allow the VPN connection to connect to the vCenter, allowing the administrator to access and manage the VMware Cloud environment.

The best option for a cloud administrator who wants to deploy a VMware Cloud software-defined data center (SDDC) on a cloud provider and requires a consistent 4.5 Gbps bandwidth from applications to communicate from on-premises to the SDDC is a Route-Based Virtual Private Network (VPN). This type of connection offers enhanced performance  [1] [2] , flexibility, scalability, and security compared to other options, such as Policy-Based Virtual Private Network (VPN), Private L2 Virtual Private Network (VPN), or Private Line.

According to the VMware official site, " Route-based VPN enables a secure connection between two or more sites, or between a site and a mobile user, and provides better performance and scalability than a policy-based VPN. Route-based VPNs are also more secure than policy-based VPNs, because the traffic is encrypted with a unique encryption key for each tunnel, rather than relying on a shared key for all tunnels. This allows for secure and reliable connections for devices and applications located in different physical locations. " [1]

[1]  https://docs.vmware.com/en/VMware-NSX-Data-Center/2.4/com.vmware.nsx.admin.doc/GUID-D6B7B9E9-E134-4C8A-8F2E-1C60A2FEDC1A.html

Private L2 VPN:  To migrate running VMs between SDDCs in different geographical locations.

You use a private layer 2 (L2) VPN to extend an on-premises network to your cloud SDDC. This extended network is a single subnet with a single broadcast domain.

You can use L2 VPNs to migrate VMs to and from your cloud SDDC, for disaster recovery, or for dynamic access to cloud computing resources (often called cloud bursting).

VM migrations across an L2 VPN support VLAN tagging and GENEVE frame encapsulation when migrating between a cloud SDDC to another SDDC.

The L2 VPN tunnel extends layer 2 networks across geographic sites. VMs can move across sites (using vSphere vMotion) and keep the same IP addresses using an L2 VPN.

The CloudAdmin role has the privileges necessary to create and manage SDDC workloads and related objects such as storage policies, content libraries, vSphere tags, and resource pools

The CloudAdmin role has the following privileges in SDDC Version 1.18.
