The team at parallo has been very helpful in our transition from traditional data centers into cloud environments (Azure).
They can help with any aspect of your infrastructure needs including but not limited too network configuration/design as well as virtual machine design & deployment using tools like VMWare or Hyper-V Manager. I would say that they understand how business applications work best when deployed within an enterprise architecture so their recommendations tend be more holistic rather then just focusing solely upon technical issues such as performance tuning etc.. We recently implemented Microsoft Teams throughout all departments which was one part where it really helped us out is knowing what works better together vs individual apps / software platforms.
