Re: Colo in Africa
Go look at the actual specifications for one of the metal boxes - you are not going to come close to maxing anything out with the workload you describe. FSB hasn't been a thing in over a decade. If you really wanted to go crazy you could do some build a custom solution in FPGA on the F1s. It's a moot point since none of this is going to be available in time but perf is a bogus reason and a lot of the times price is too.

Re: Colo in Africa
Thanks for chiming in but his reason for can't be cloud was, "We use the full capacity of each server, all the time." That ain't good reason. They do have baremetal servers like I pointed out. We use them when for cases where we need access to perf counters.

Re: Colo in Africa
My bad. They announced that Oct 2018 so I figured they'd be close to it now. Yeah turns out it's mid 2020 :-( https://aws.amazon.com/blogs/aws/in-the-works-aws-region-in-south-africa/ On Tue, Jul 16, 2019 at 4:02 PM Chris Knipe wrote: > > > On Tue, Jul 16, 2019 at 4:57 PM Akshay Kumar via NANOG > wrote: > >> The 2nd requirement seems artificial.

Re: Colo in Africa
The 2nd requirement seems artificial. The new hypervisors have come a long way and the overhead is minimal. Also you can run bare metal instances in AWS if you really need them with 100Gbps. Just just use the South Africa AWS region. On Tue, Jul 16, 2019 at 3:35 PM Ken Gilmour wrote: > Hi Folks, > > I work for a Security Analytics org and we're looking to build a small POP > in Africa.
