  • How many overflows can I add?
    As many as you want. Although there's a practical limit as to how many overflows should be added to your stack - contact our team for guidance.
  • Do I need to change my store to use overflow servers?
    No. MageStack is built to scale horizontally, so new servers can be added to your stack without changing the way you work on your store.
  • Can I autoscale?
    Absolutely! Just set your thresholds, limits and monthly budgets and let auto-scaling monitor your stack and provision resource on demand.

Real Configurations

See how overflows perform in real life campaigns
  • Single high traffic campaign
    Overflow servers were added to support a planned high traffic flash sale, featured on national television, national newspapers and social media.

    The customer's stack of 2x 40-Core servers was increased for a single day by 12x overflow servers, to provide instant additional capacity to cope with the extremely high traffic volumes.
  • Frequent high traffic campaigns
    A special promotion, run bi-monthly with a limited number of units draws a massive number of visitors from the brand's huge Instagram following.

    Where fixed resources would have a large permanent increase in costs, overflow servers are perfect allowing huge scaling for just a couple of days per month at a low cost.
