Those solutions can be simple application offerings, like WordPress or Apache Server, as well as highly complex applications, like SAP, network appliances, or Citrix deployments. 

The following are some examples of Azure Marketplace apps and solutions: 

• Windows Server 2008, R2 SP1
• Web App
• Virtual Network
• SQL database
• CHEF
