Hi Alex, I`d like to know more about how the infrastructure fits together, I know the basics but I reckon having something which I can play around with (break and fix it) would be the best way.
so I think the simulator might do the job, maybe later look at a full deployment Thanks On Mon, 8 Mar 2021 at 10:09, Alex Mattioli <alex.matti...@shapeblue.com> wrote: > Hi Craig, > Building on what Rohit and others explained, it depends a lot on your goal > as well. > > If you want to develop software for ACS, then the simulator is probably > the way to go. > If you want to dig into the physical infrastructure with multiple > hypervisor types, etc..etc.. then your best bet is most likely to be one > "large" hypervisor (8 cores, 32GB RAM), with that you can run a pretty > realistic nested environment with NFS servers, multiple zones, etc.... > If the goal is to actually simulate a physical infra, then a bunch of PIs > is a good option. > > So, before building an actual lab I'd recommend you come up with some > goals for your lab setup. > Hope this helps, > > Cheers, > Alex > > alex.matti...@shapeblue.com > www.shapeblue.com > 3 London Bridge Street, 3rd floor, News Building, London SE1 9SGUK > @shapeblue > > > > > -----Original Message----- > From: Rohit Yadav <rohit.ya...@shapeblue.com> > Sent: 07 March 2021 15:41 > To: users@cloudstack.apache.org > Subject: Re: Cloudstack lab > > Hi Craig, > > The simulator is a dummy hypervisor that essentially uses the database > (MySQL) to simulate resources (such as hosts, VMs, disks etc) while using > the same orchestration/business logic as would any hypervisor.
