Deploy a website with Azure virtual machines Flashcards
Can you change the size of your vm after it’s created?
Azure allows you to change the VM size when the existing size no longer meets your needs. You can upgrade or downgrade the VM - as long as your current hardware configuration is allowed in the new size.
There are two separate costs the subscription will be charged for every VM:
compute and storage.
Azure Backup can be used for a wide range of data backup scenarios, such as:
- Files and folders on Windows OS machines (physical or virtual, local or cloud)
- Application-aware snapshots (Volume Shadow Copy Service)
- Popular Microsoft server workloads such as Microsoft SQL Server, Microsoft SharePoint, and Microsoft Exchange
- Native support for Azure Virtual Machines, both Windows, and Linux
- Linux and Windows 10 client machines
Does Azure Back up charge you for the data that’s been transfered?
No, it’s free.
Is there a limit to how much data you can transfer with Azure Back up?
No, unlimited.
What is SSH?
A secure way to access a computer over an unsecured network.
SSH, also known as Secure Shell or Secure Socket Shell, is a network protocol that gives users, particularly system administrators, a secure way to access a computer over an unsecured network.
Which two approaches are there to authenticate an SSH connection?
- username and password
- SSH key pair
What are the two parts of an SSH key pair?
- Public key: can be shared with anyone.
- Private key: used as verification. Confidential.
To connect to the VM via SSH, you need the following items:
- Public IP address of the VM
- Username of the local account on the VM
- Public key configured in that account
- Access to the corresponding private key
- Port 22 open on the VM
What is the effect of the default network security settings for a new virtual machine?
Outbound request are allowed. Inbound traffic is only allowed from within the virtual network.
What does MEAN mean?
MEAN is a development stack for building and hosting web applications. MEAN is an acronym for its component parts: MongoDB, Express, AngularJS, and Node.js.
Why would I pick MEAN?
Javascript is your strong skill, Your data is semi-structured (JSON), it’s well documented and it runs almost anywhere.
Why might MEAN not be right for me?
Your data is highly structured, JavaScript is not your strongest skill,
What’s the role of AngularJS in the MEAN stack?
AngularJS implements data binding for HTML and JavaScript. For example, you can use AngularJS to retrieve items from a database and display those items in the UI.
