This information is also important to ensure that this information is what you expect, otherwise you may use the wrong account or run or store things in the wrong place.  It is important to be clear about these terms as they are often different in other cloud providers. \n",

    ": If you click on the hamburger (three horizontal lines) you will get a dropdown menu and see a list of frequently used services that are offered by Azure. Currently, Azure has over 200 services ranging from compute to machine learning to networking to data storage. The list grows frequently!\n",
    "\n",
    "**2. Search bar**\n",
    ": You can also use the search bar to find a particular service or offering that you are \n",
    "interested in. For example, if you wanted to provision or utilize a \"virtual machine\", \n",
    "you can try using the search bar to search for \"Virtual Machines\".  As you start typing, \n",
    "the words starting with \"V\" it will auto fill. Choose Virtual Machines from the options displayed.\n",
    "\n",
    "**3. Cloud Shell**\n",
    ": The cloud shell button invokes an interactive shell environment for either bash or PowerShell. The first time you invoke cloud shell you will also create persistent storage specifically for cloud shell.  The cloud shell comes with linux tools like bash, sh, & dig as well as the Azure CLI.  Cloud shell also has editors like VIM and emacs, and tools like git, make, and configuration tools like ansible & terraform, already installed.  Language support for python, go, java, & PowerShell are also preinstalled. Azure Cloud Shell runs on Ubuntu with persistent storage.\n",
    "\n",
    "**4. Directories & Subscriptions**\n",
    ": This button will show the current Subscription and Active Directory (not covered) associated with your account.  For these episodes you can think of a Subscription as your your billing account (For more information on Active Directories and Subscriptions, see the *glossary of Azure terms* link above).  You use this dropdown to verify that you are using the right subscription.\n",
    "\n",
    "**5. IAM Username and Organization**\n",
    ": The menu bar on the console also lists your username and the current organization that you are logged into. IAM is short for Identity and Access Management. Identity is a mechanism to authenticate users (e.g. password) and Access is a mechanism for authorizing what kinds of services users have access to. In the creation of an IAM user, the administrator (overlord) of the account assigns a particular permission scope (in Azure this is known as roles) to control access to a particular set of services and also assign a password to authenticate user login. IAM is a key component in managing security on the cloud.\n"
