In my experience, the R3/R4 family works best for Varnish. Varnish isn't great at spreading the load across multiple cores, but it will fully utilize all the ram you give it.
I like to run an ASG of size 2 as the front door to the side. This maximizes availability, and keeps cache fragmentation to a minimum, and protects you from most AZ issues and single instance hardware issues. -Jason On Fri, Mar 10, 2017 at 5:05 PM, Dridi Boukelmoune <[email protected]> wrote: > On Fri, Mar 10, 2017 at 9:16 PM, Craig Servin > <[email protected]> wrote: > > We found that we run into the network IO limits before we had CPU issues. > > You have to use trial and error to figure out how much IO you can get > from > > each instance type as we couldn't find good documentation defining that. > > However it seemed that the network limit goes up as you step up machine > > sizes in each family. > > CPU usage tends to grow with features like compression or ESI, VMODs > may also burn cycles depending on their purpose. > > Dridi > > _______________________________________________ > varnish-misc mailing list > [email protected] > https://www.varnish-cache.org/lists/mailman/listinfo/varnish-misc >
