On our shared hosting packages, we have set plans in place with set resources and quotas. If you have reached the limit on resources on your current plan, it is usually very straight forward to upgrade to the next plan. We also offer VPS Server hosting, which allow for much more flexibility when it comes to the resources you need.
For help in picking out the ideal hosting package for your needs, please get in contact with our Sales team and they will be happy to advise further.
