What is the command to restart IIS services on the command line?

What is the command to restart IIS services on the command line?

• iisrestart
• iisreset
• iisrecycle
• iisrefresh 

EXPLANATION

An IIS server can be restarted without rebooting the entire machine by running the iisreset command on the command line.  There is a button on the IIS management console that can also do this; additionally, you can manually restart the services involved.


Take IISReset as a suite of commands that helps you manage IIS start / stop etc.
Which means you need to specify option (/switch) what you want to do to carry any operation.
Default behavior OR default switch is /restart with iisreset so you do not need to run command twice with /start and /stop.
Hope this clarifies your question. Check this MS DOS help picture you will understand.

I have some private servers on my premises, also I have distributed some of my workload on the public cloud, what is this architecture called?

I have some private servers on my premises, also I have distributed some of my workload on the public cloud, what is this architecture called?

• Hybrid Cloud
• Private Cloud
• Public Cloud
• Virtual Private Cloud 

 

EXPLANATION

This type of architecture would be a hybrid cloud. Why? Because we are using both, the public cloud, and your on premises servers i.e the private cloud. To make this hybrid architecture easy to use, wouldn’t it be better if your private and public cloud were all on the same
network(virtually). This is established by including your public cloud servers in a virtual private cloud, and connecting this virtual cloud with your on premise servers using a VPN(Virtual Private Network).
