Applications

• For running applications on a broader note we have
  • physical servers
  • virtual machines
• In the case of Virtual Machines, each physical server will have an Hypervisor (VmWare ESXi, Hyper-V).
• To control hypervisors on multiple machines, organizations use Hypervisor controllers like VCenter, System Center
  
• In the virtual machine the os mostly can be linux or windows

Databases

• Here broadly we have two kinds of Databases running on physical server or vm’s
  • Relational Databases Engines (Oracle, Microsoft SQL Server, mySQL, Postgresql)
