An e-shop loads catalog, sessions, payments and often Skroutz feeds. Shared hosting that “works” for a corporate site often fails during sales or after campaigns.
Ask for SSD/NVMe (or equivalent), CDN for static assets, valid SSL, headroom for spikes, careful database care and backups before major catalog changes.
Capacity and scaling path, staging for checkout tests, monitoring in peak hours and a clear plan for transactional email after launch.
