Hopefully this is correct group to ask that question...
What is the difference between HVD technology and new WVD? My understanding both run in the cloud, provide simplified centralized management, and both support RDS (Remote Desktop Services).
So what is different and what are the advantages of new WVD vs. "old" HVD?
As far as I can tell, Hosted Virtual Desktop (HVD) often referred to as a cloud-hosted virtual desktop, is an interface that delivers applications and data that are stored on a cloud provider’s servers instead of the user’s computer or corporate network also it's known as Desktop as a Service (DaaS) so this is the delivery model or technology, but both are the same, just Microsoft created its own (WVD), like Citrix as well they have another Daas called Citrix Managed Desktops

Has anyone seen anything on Windows Server 2019 that would prevent browsing the network in a Active Directory domain environment to find available OPC servers on remote hosts when all other OPC communications seem to be functioning normally and file share browsing seems to also be functioning?
There is something I'm missing here, but I cannot find it. Since the core OPC functions are working, tools like OPC Expert are not showing any errors and guides for DCOM settings from OSIsoft, KEPware, and OSI Institute are all being used to no avail. None of the DCOM settings seem to be addressing the CLSID network browsing. If a client has the ability to supply a remote host and query that host, the OPC services enumeration works just fine. The problem is that we are attempting to use clients that do not have any features to manually define the servers and solely relies on the network browsing functions.
Please tell me someone else has seen this behavior. I suspect that it is some network security feature of Windows Server 2019, but I can't find any documentation that points to what might be causing this function to fail. Worse, the function is completing normally, but with zero results, so I don't even have error messages to track the issue down with.
It really depends on the application you are using. There are many ways for an OPC Client to find the remote OPC Server. Most clients will use a combination of the folowing:
OPCEnum. In particular the heavy lifting is done using EnumClassesOfCategories which is part of Component categories Manager. Does not crawl through registry.
GetOPCServers(). This is a method is available as part of an interface called IOPCAutoServer which comes from the OPC foundation itself (via OPCDAAuto.dll)
CLSIDFromProgID() first to get the CLSID and then does the CoCreateInstanceEx().
When CLSIDFromProgID() fails, it falls back to using OPCEnum to list all OPC servers before making a connection.
That means that you would first need to find out what your client application is using to list the OPC Servers.
Then, on the Windows Security side of things, depending on the OS version of both nodes, you may need to disable Simple File Sharing mode (that is the case for Windows XP and older)
If it uses OPCEnum, you will need to configure DCOM for OPCEnum as well, which is the recommended method to list remote OPC Servers.
If the application only supports remote registry lookup to find the OPC Server, then you will need to grant access to the account connecting from the client to the Server
[azure] simple question. What exactly a hybrid can do and can not do? I have a Win Server 2019 on premises. Does a hybrid Win Server in Azure acts as a mirrow of my premises server? I have an accounting software running on the premises server and will like to explore how will the azure provides a way for remote clients to access the accounting file using Remote desktop
1.Total number of user login a GCP instance allow at a time?
2.How server resource get allocated among the jobs ran by concurrent user active any point of time?
3.Can we access google cloud server from any part of the world,how?If no,why?
For GCE instances, the limiting factor on concurrent connections is the OS. For Windows server, without Remote Desktop Services (and associated licenses), the limit is 2. On Linux machines, the limit is determined by the sshd_config file for MaxSessions and MaxStartups
Server resources are allocated based on the OS once again. For Linux, this can be by restricting on a per-user basis. As for Windows, there are different ways to enforce limits depending on the version you choose and how you deploy the server.
You can access the Google Cloud Platform and all the resources from almost anywhere in the world (with some exceptions) by access the external IP address of your instance, connecting to your Management console (console.cloud.google.com), or by running the Google Cloud SDK from your machine
Dummy question here, I'm pretty new to some stuff like setting up server configuration, etc.
So my question is, can i set up a LAMP virtual machine and use it as a real server?
I mean can the web pages in the www directory be accessed from another computer like if it was a regular server??
Simple Answer: Yes
The VM has to have its network interface routed to the host machine to be accessible from host's network.
How this is done depends on the OS and VM software.
Does anyone know of a clustering/load balancing software(free or commercial) that once setup, only requires you to login at one place and all hard drives are mounted together as one?
For example, currently i have 1 server which i access by going to www.myurl.com/cpanel and one hard-drive is displayed and i upload all my website files there.
If I had 100 linux or windows servers connected together using load balancers and wanted to run them as a cluster, is there software where i can just go to www.myurl.com/cpanel and once i login i will not see more than 1 hard drive, but instead i will see the total space of ALL hard-drives, so i can just upload 1 file and it will automatically be uploaded to all the hard drives?
If a software like this is not currently available, do you think it'll be possible to program something like this? Or is there a software where you put a file on your website, and website visitors download it and once they run the file and are connected to the internet, their internet connection becomes part of your web server, so when people access your website, some data and cpu usage comes from your web server and some data and cpu usage from users who downloaded the file?
You're talking about 2 different things in your question - mirrored drives and distributed storage.
There are SAN (Storage Area Network) products from EMC for example that can do things that blow your mind with the way storage is handled. There are other local disk to SAN technologies like iSCSI also.
For what you want to do, you want to mirror a folder across 100 servers. I think *nix servers have a RSYNC technology, and Windows Server 2003 R2 has File Replication Services. I do know that FRS (part of Distributed File System technology) will do exactly what you want to do and it comes out of the box in Windows Server 2003 (R2 only) and 2008.
Look at Direct Attached Storage and Storage Area Network.
From what I can tell, the DAS is cheaper as it runs over existing network infrastructure, while a SAN essentially has its own dedicated fiber network that is parallel to the regular network.
actually that wikipedia link is old.. see dell's DAS options for a better example.
