The Basic pricing tier includes core Azure Web Sites; up to three instances of dedicated Virtual Machine running web sites, SSL support, scheduled jobs, endpoint monitoring and more, according to today's blog post. The price of Web Sites Basic ranges from about $56 a month for a small instance, to about $224 for a large instance.
With the new additional tier, Microsoft now offers free Azure Web Sites for evaluation purposes (with no SLA); Shared Web Sites, which are limited in capacity and feature set (also with no SLA); Basic Web Sites; and Standard Web Sites, which provide high availability and support for dev-ops type tasks.
Any existing Web sites already running on Azure, whether in free, shared or standard mode, retain their current mode. However, the Standard SKU now includes more storage, a free SSL connection and other additional features for no extra charge beyond what a user is paying currently, according to the post.
