01What to ask the provider
SLA, location of the data center relative to the audience, backups and test restore, SSL, DDoS protection, staging convenience.
02Typical scenarios
Landing/blog — quality managed. Medium CMS projects — VPS with monitoring. High load — cloud + CDN + observability.
03Red flags
There are no backups, eternal "technical work", shared IP in spam lists, no HTTP/2/3.
