Hosting question

What hosting would you recommend for a news/media website based in WordPress (PHP – total instillation size = 2.2GB + ~5MB of media files & ~10 articles being added daily), 5,000 daily visitors, and 10-15 total registered website users? The goal is performance and security. I would like to set up my own instance directly on the cloud. I would not like to use an ISP/WP web hosting company. I need to go with a company that provides on-demand cloud computing and has their own datacenters (i.e. Azure, AWS, DigitalOcean etc.).
