With this type of class, students learn how to handle large volumes of data, and apply machine and statistical learning algorithms to derive data insights. A key objective for students is to learn to use data analytics tools, such as Apache Hadoop's open-source software package which provides tools for storing, managing, and processing big data.

 # Use Classroom Labs for trainings
-You can set up a lab for trainings. Classroom Labs of Azure Lab Services allow you to create a lab for your training where each trainee uses identical and isolated environments for training. You can apply policies to ensure that training environments are available to each trainee only when they need them and contain enough resources - such as virtual machines - required for the training. 
+Azure Labs Services allows professors, trainers, or teaching assistants to quickly and easily create an online lab to provision pre-configured learning environments for the trainees. Each trainee would be able use identical and isolated environments for the training. Policies can be applied to ensure that the training environments are available to each trainee only when they need them and contain enough resources - such as virtual machines - required for the training.

 There is also an option to provide **Address range** for virtual machines for the labs.  The **Address range** property only applies if **Peer virtual network** is enabled for the lab.  If the address range is provided, all the virtual machines in the labs under the lab account will be created in that address range. The address range should be in CIDR notation (e.g. 10.20.0.0/20) and not overlap with any existing address ranges.  When providing an address range, it's important to think about the number of *labs* that will be created and provide an address range to accommodate that. Lab Services assumes a maximum of 512 virtual machines per lab.  For example, an ip range with '/23' can create only one lab.  A range with a '/21' will allow for the creation of four labs.
 
-If the **Address range** is not specified, Lab Services will use the default address range given to it by Azure when creating the virtual network to be peered with your virtual network.  The range is often something like 10.x.0.0/16.  This may lead to ip range overlap, so make sure to either specify and address range in the lab settings or check the address range of your virtual network being peered.
