Where is the elusive Hyper-V 2019

@scottalanmiller provided us with 2019 link
https://www.microsoft.com/en-us/evalcenter/evaluate-hyper-v-server-2019

But what happens when you wish to try
Hyper-V 2019

When you want to download it it says

Microsoft Hyper-V Server 2019
Evaluations | Unlimited

    Following the launch of Windows Server 2019, we started the process of publishing the media for the 180-day evaluation media. In the process, we found an issue with the Eval media and are in the process of fixing it. We will publish an update on its availability on the Windows Server blog once the Eval media is available. In the meantime, if you are looking to try Windows Server 2019, you can do it in Azure for free. Windows Server 2019 is available in Azure and you can get up to 750 hours of Windows virtual machine with your Azure free account. Please note that this does not affect the Windows Server 2019 media for purchase that is available in the usual channels

I dont get it what is this issue
https://cloudblogs.microsoft.com/windowsserver/2018/11/13/update-on-windows-server-2019-availability/
have to do with Hyper V ? and why not it is not affecting 2019 Server ?

seems like they are clearing the way for 2019 and just screwing with everyone else that wants Hyper V

@Emad-R

Another Reason why KVM is superior.

Btw I tried Hyper V manager on Win10, and used Gen2 VMs as oppose to using my standard VMware Workstation or Player or VirtualBox, and I was unable to complete the OS install cause it did some checkups on the VM and ISO and told me that the licensing was not valid, however I think cause I slipstreamed offline updates on the ISO that caused the issue.

It feels when you even wish to try MS stuff, they try to give you the finger some how.

Many thanks for this I never heard of this project, glad finally we have UI for either SS or Ansible

@IRJ

Have you ever used snaps ? if so containers if done properly will help greatly in update and rollback, an example how not to do it :

Ubuntu host OS running ubuntu container image with LAMP installed , you will not leverage the power of containers.

However if you have Ubuntu host OS with multiple containers like apache, php, database (some argue you dont put database in a container ) this way you can test and update your CODE app easily, as it became seperate from the OS, and you can test the updates easier, and rollback them also easier.

No more snapshotting VMs and exporting and importing, and wiping free space to reduce size.

@scottalanmiller

WP autoupdates man by itself, it is super easy and simple.

However I think many folks are moving to self documenting systems or without DB, I never used them but heard of them.

You just have to use WP with like 1-5 plugins, no need for 100, and it will be perfect.

IT IS FRIEKN ssh TERMINAL IN WINDOWS WITH SUPPORT for SSH and key based auth, and no more putty and kitty and weird nonstandard .ppk format.

I use Xubuntu 18.04 at Work, but have Win10 on my desktop for steam gaming, although ... I rarely played anything for like 3 months now.

@scottalanmiller said in Another VPS Kid on the block upcloud.com:

And if you did LXC instead of KVM, it reduces RAM needs significantly. Because the kernel RAM is shared rather than repeated.

I'm learning a lot about LXD , and preparing video screen guide for ML

Vultr new service is killing everyone, I just wait for it to be available in other regions. Called high freq VMs

Hi,

Been time since I posted something... trying to find a job in Toronto, and not purchasing everything I see here.

So this is an easy and insecure way to set it up in one server for testing and no need for FQDN. I highly recommend Vultr high freq VMs, at least the 24$ one with 4 GB RAM, the more the better.

Thats it, be sure to replace

• SERVERPUBIP with your Server Public IP

• Asia/Amman and with your Timezone

• Omit --- in nano commands, don't type those.

Interesting, thanks.

@Emad-R

Very good read:

https://linuxhint.com/lxd-vs-docker/

Seems RHEL is alot involved in Centos 8 nowadays, I'm starting to think that maybe scott was right and using those old/stable distros just adds extra hassle and effort, it seems they are stating that as well with the unexpected stream version (stupid name).

So something like Alpine/Arch/Ubuntu/Fedora

Seems like a better choice for easier distro updates.

I believe currently the containers management/orchestration market (the only way to run in Production) has a different status than containers, sure you can easily run docker anywhere, but you can't say the same on k8s. I rarely see a production k8s cluster managed by a person/team and not handing that over to a could provider, the same can not be said to ESXi/KVM/Hyper-V.

The only propper truly open implementation for containers I really liked was Canonical LXD, really no proprietary format what so ever you actually export the container as tar.gz image, and management system is baked in using advanced filesystem like ZFS. however sadly due to politics, it is not being implemented widely and I think RHEL/Centos actually dropped library from their repository to stop allowing successful and easy install of LXD on their OS.

I feel everyone jumped on the wagon and screwed things up, or they are attracting you to only to screw you over, cause the prices of k8s cluster is huge at the moment, which begs the question you can pay the below for 3 node k8s cluster from Google/Amazon/Azure

$2,052 per month ($1,539 with discounts) $2,880 per month $2,880 per month
source:
https://www.nirmata.com/2019/03/20/comparing-cloud-hosted-kubernetes-providers-google-gke-vs-microsoft-aks-vs-amazon-eks/

So the cheapest option for a 3 node is 2000 $ (disregarding other costs ), well I get the autoscaling part and everything but for that amount of money, you can get 80 of those distributed VPS at many countries, like who needs auto-scaling if you have 80 VMs world wide.

128 GB SSD
2 CPU
4 GB

Why do you need a cow when you get milk for free (alot cheaper). seems like they want to allow developers to make decisions

Why in God's green earth would you deploy XP today? Or would you continue to operate Windows XP?

The system it runs has an $80,000 camera on it

Also this seems insane that the customer has an $80,000 camera, but can't or won't purchase an updated system to run it.

Sadly, there are many. hehe x2

I had to deal with clients that paid 100K for unnecessary server room safety and ridiculous hardware that we dont need, and when I told them to get support subscription-like from canonical they were like nah your smart we dont need that.

@scottalanmiller

I might work as system admin for such company that offers SAP, can you give me summary. on SAP/HANA on linux if possible

SAP itself is the world's largest ERP maker. Like most ERPs, they are heavily driven by their underlying database. Traditionally SAP used "old fashioned" relational databases from third parties with Oracle DB and MS SQL Server being the most common.

In recent years, SAP decided that relational data and third parties were not right for their customers for many reasons. Performance, flexibility, complexity, and cost. Third party database licensing was causing a huge portion of the cost of an SAP implementation to go to SAP's competitors (all of the DB makers made their own ERPs.) So customers were paying too much, and getting too little.

HANA is a NoSQL database made by SAP that improves performance and flexibility on SAP's products, while lowering cost and allowing SAP to do greater integration and simplify deployments. It's a huge win for both SAP and customers. The only losers are third parties who were making huge profits while adding little to nothing to do the ecosystem.

Like always , you deliver

@wrx7m

I really hope there is vCenter somewhere, and you're not just using vanilla ESXi host and licensing that.

Paying for just type-1 hypervisor is like paying stripper for dance, sure it is fun but its is not going anywhere, not for you or her. and at the end of the song your 20 dollars short.

YAST is ncruses tool in server mode but GUI when you have a desktop environment. Amazing tool, I know we can do all of those by typing but at the same time I wonder how mujch time this saves, and the learning curve is much easier. Also ncurses have no overhead.

@JaredBusch said in Looking for a 10 inch or so android tablet:

A couple years ago we ordered a number of Galaxy Tab 10. They have generally worked.

The current version of them will also likely work well. But they are $250, so it is worth a short amount of time to look for other models.

this is the best option, the 2019 model has no competition.

To be honest, seems like MS lobbying in the works. I bet they gave the politicians a sweet deal and bam who cares about end users
