I use the lowest cost vps and domain name I can find. OVH black Friday deals and lcn free UK domains as a starting point and practice moving host and registrar so as not to be dependent on either. Only after you are independent of vendors is it worth taking this approach IMHO. Beware if you “forget” to renew your domain many sharks about will take it, gather your data or ransom the name.
