  This post outlines critical design decisions architects should consider when planning and deploying VMware Cloud Foundation (VCF). 1. VCF Constructs and Architecture VCF private cloud is composed of hierarchical constructs with clear management responsibilities: VCF Instance:  Includes a management domain and optional workload domains with core components such as vCenter, NSX, SDDC Manager, and ESX hosts. VCF Fleet:  Manages one or more VCF Instances along with fleet-level components like VCF Operations and VCF Automation. VCF Private Cloud:  Represents the highest level aggregating one or more VCF Fleets. Architects must design with these constructs in mind, determining how many instances and fleets are needed based on scale, organizational boundaries, and operational models. 2. VCF Operations Deployment Models VCF Operations is the central management console with deployment options affecting availability and recovery: Simple Model:  Single node, minimal foot...

Getting Started with Microsoft Azure VMware Solution (AVS)   As organizations modernize their infrastructure, many face a critical decision: migrate VMware workloads to the cloud using Azure VMware Solution (AVS) or refactor them for Azure-native services. This post walks you through what AVS is, how to set it up (with visuals), and how its costs compare to Azure-native alternatives.   What is Azure VMware Solution (AVS)? AVS is a fully managed VMware environment hosted on Azure. It allows you to run VMware workloads natively on Azure without refactoring or rearchitecting your applications. It includes: vSphere, vSAN, NSX-T, and HCX Seamless integration with Azure services Support for hybrid scenarios with ExpressRoute     How to Set Up Azure VMware Solution   Step 1: Plan Your Deployment Before deploying, gather: Azure subscription (EA, CSP, or MCA) Resource group and region CIDR block for...

VMware Hypervisor   A VMware hypervisor is a software layer that allows a physical computer to run multiple virtual machines (VMs) at the same time:  How it works: A hypervisor acts as an intermediary between the physical computer's resources and the operating systems (OS) running on the VMs. It allocates the computer's resources, like memory and processing, to each VM, and isolates them so they can run independently.  Benefits: A hypervisor allows you to run multiple operating systems without rebooting the computer. It also protects sensitive data with encryption, and makes it easier to manage and audit the VMs.  VMware hypervisor products VMware offers a variety of hypervisor products, including:  VMware Workstation Pro: A desktop hypervisor for Windows that allows you to run Windows, Linux, and other VMs  VMware Fusion: A desktop hypervisor for Mac that allows you to run VMs  ESXi: A native hypervisor that's part of the VMware Infrastructure softwar...

Issue details:-   Password remediation tasks on SDDC manager getting failed with below error. However, we are able to connect SSH with root password on the vROPS appliances, no issues with credentials. I checked Operations logs on SDDC manager and found below logs, indicating the SSH connectivity issues from SDDC to vROPS appliances. Tried to do SSH vROPS appliance from SDDC manager, getting below error... Seems some issue with ECDSA key.. Resolution:- SSH to vROPS appliance and retrieve the ECDSA ssh keys as below. Now, we have 2 options to update the correct SSH keys for vROPS appliance on SDDC manager known_Hosts files located at below location.   /root/.ssh/known_hosts   /etc/vmware/vcf/commonsvcs/known_hosts   /home/vcf/.ssh/known_hosts   /opt/vmware/vcf/commonsvcs/defaults/hosts/known_hosts First option is manually copy and paste the SSH key on all the known_hosts files and restart the SDDC manager services and then try to remediate the password again...

 Hello, As you all know that VMware NSX has native Load Balancing capabilities which provides Basic Load balancing to the virtualized environment.  But now VMware is planning to depreciate the native load balancing features and asking the VMware NSX customers to move to AVI Load Balancer product which will give advanced level of load balancing features which are supported by other third party LB vendors like F5, Cisco ACE etc... VMware NSX Advanced Load Balancer (Avi) is an API (Application Programming Interface) first, self-service Multi-Cloud Application Services Platform that ensures consistent application delivery, bringing software load balancers, web application firewall (WAF), and container Ingress for applications across data centers and clouds.    VMware’s Avi is a modern, software-defined elastic application delivery fabric. It is composed of a central control plane and a distributed data plane. VMware Avi Controller provides a centralized policy engi...

  Hello There, In this article, i am covering how to migrate the ESXi host switch from N-VDS to VDS 7.0 switch in NSX-T 3.2.x version. When using N-VDS as the host switch,  NSX-T  is represented as an opaque network in  vCenter Server . N-VDS owns one or more of the physical interfaces (pNICs) on the transport node, and port configuration is performed from  NSX-T Data Center . You can migrate your host switch to  vSphere  Distributed Switch (VDS) 7.0 for optimal pNIC usage and manage the networking for  NSX-T  hosts from  vCenter Server . When running  NSX-T  on a VDS switch, a segment is represented as an  NSX-T  Distributed Virtual Port Groups. Any changes to the segments on the  NSX-T  network are synchronized in  vCenter Server. We have an NSX-T environment running with NSX-T 3.2.2.1 version. this environment was designed and implemented with NSX-T 2.x version and that time we used the N-VDS as host...
