Technische specificaties van de servers

Onze applicaties bieden we aan in de pakketten 'standard' en 'plus'. De applicatie heeft in beide pakketten steeds exact dezelfde functionaliteit. Het verschil in beide pakketten zit in de hardware specificaties van de server.

Upgraden en downgraden

Upgraden

Wanneer je bij het bestelproces bijvoorbeeld gekozen hebt voor een 'Standard' pakket, dan kan je dit steeds laten upgraden naar een 'Plus' pakket. Dit kan noodzakelijk zijn om bijvoorbeeld meer processor-kracht of meer RAM geheugen kunnen in te zetten, of om de opslagruimte te verhogen.

Downgraden

Als een server bijvoorbeeld van het 'Standard' naar het 'Plus' pakket wordt geupgrade, dan heb je de keuze om enkel de processor (CPU) en het RAM-geheugen te upgraden, of ook de opslagruimte. Wanneer enkel processor en het RAM-geheugen geupgrade wordt, dan kan in de toekomst steeds een downgrade naar het 'Standard' pakket gebeuren. Wanneer ook de opslagruimte geupgrade werd, dan is een downgrade niet meer mogelijk.

Algemene specificaties

Onze virtuele machines worden gehost op servers waarbij de processor en het RAM-geheugen gedeeld worden met andere virtuele machines. Op aanvraag is het mogelijk om dedicated vCPU's te gebruiken.

  • Processor: de exacte CPU GHz kan verschillen, maar zal steeds minimaal 2GHz bedragen. Als processor wordt steeds een AMD EPYC 2nd Gen of een Intel® Xeon® Gold gebruikt (1 vCPU = 1 hyper-thread).
  • RAM-geheugen: het geheugen is steeds ECC-geheugen.
  • Opslagruimte: lokale NVMe SSD's op RAID10.
  • IP-adressen: er wordt steeds 1 IPv4 en 1 IPv6 adres voorzien. Extra IPv4 adressen zijn tegen extra kost verkrijgbaar. Extra IPv6 adressen worden kosteloos toegewezen moest dit noodzakelijk zijn.
  • Netwerk: de server is met een redundante verbinding verbonden met het internet. De netwerksnelheid kan wisselen naar gelang de drukte op dat moment van de dag.

Applicaties

In onderstaand overzicht volgt een beschrijving van de exacte server specificaties per applicatie en per pakket. De servers zijn steeds virtuele servers.

    Benchmarks

    Onderstaande benchmarks werden uitgevoerd op een virtuele server met 2 vCPU's en 4 GB RAM-geheugen.

    Opslagruimte

    Om benchmarks op de opslagruimte uit te voeren, gebruikte we fio versie 3.25.
