IaaS (Infrastructure as a Service)

For example: Azure Virtual Machines are fully operational virtual compute devices running in Microsoft's datacenters. An advantage of this cloud service model is rapid deployment of new compute devices; setting up a new virtual machine is considerably faster than procuring, installing, and configuring a physical server.

SaaS (Software as a Service)

Azure Functions -

Data about each product that's sold at Tailwind Traders is packaged up as a JSON message and sent to an event hub. The event hub distributes the JSON message to subscribers allowing different systems to be notified. Tailwind Traders wants to upgrade their eCommerce site to include real-time inventory tracking. Currently, the website updates product availability each night at 2:00 AM. A Windows Service written in C# contains all of the necessary logic to retrieve the messages, parse the JSON, perform a look-up across multiple databases to find additional product information and potentially send notifications to the purchasing department so that they can reorder quantities that fall below certain levels. The Windows Service runs in a VM hosted on Azure. Most of the time, this system works fine. However, some products are in high demand, and some products are kept in low quantities at each store. Several times a day, customers drive to the store to pick up an item only to find that it is no longer in stock. Instead of running the algorithm on a nightly basis, they want to run the inventory updater each time a product is purchased.

Blob Storage

Microsoft's object storage solution for the cloud. It is optimized for storing massive amounts of unstructured data, such as text or binary data. lets you stream large video or audio files directly to the user's browser from anywhere in the world.

Tailwind Traders employs technologists with many different skills. A team of developers and admins build and maintain a collection of intranet applications that are vital to the business. This team has a strong background in Windows development and network administration. They moved their applications to the cloud and need a way to perform one-off testing, management, and administrative tasks on their intranet environment. They quickly realized that managing Azure from the Portal takes too much time and is not repeatable. Which tool should they use for one-off tasks?

Azure Mobile App

Tailwind Traders experiences a surge in ecommerce traffic at certain times of the year that coincide with national holidays and weekends. The first few years, the director of cloud operations has requested that everyone who manages a critical system come into the office during these important dates. However, now that Tailwind Traders has successfully operationalized most critical systems, the director wants to relax this requirement and allow employees to spend these dates with their families. Is there a product that can help in this scenario?

Azure Logic Apps

Tailwind Traders sends out invitations to participate in a customer satisfaction survey randomly after a purchase. Currently, the customer satisfaction is aggregated, averaged, and charted. However, the customer service department sees an opportunity to be proactive and reach out to customers who provide low scores and leave comments with a negative sentiment. Ideally, responses with negative customer satisfaction scores would trigger a customer retention workflow. First, a sentiment analysis would be generated based on the free-form comments, an email sent to the customer with an apology and a coupon code, and the message would be routed to a Dynamics 365 Customer Service so that a follow-up email could be scheduled. Unfortunately, there's no developer resources available to take on this project, however the customer service team works with several cloud and IT professionals who might be able to construct a solution.

Azure Portal

Tailwind Traders uses Azure extensively throughout their entire organization. To make sure both the technical team and the executive team is aware of their cloud spend, the director of cloud operations will begin to meet weekly with the Chief Financial Officer (CFO) to talk about their cloud spend. Conversations may begin at a high level, but the two may want to dive in deep during the meeting to gain more insight on how Azure resources are being used. Ideally, they would be able to see the data displayed visually, but also be able to run custom reports in real time. Which tool can they use during their meeting?

ARM Templates

Tailwind Traders wants to operationalize their cloud deployments. They need a repeatable and reliable way to scale their operations during peak sales dates. Since we'll be choosing a process for scaling our production environment, we need to ensure that our choice: Is efficient and can potentially create many resources in parallel. Creates all dependencies in the correct order. Can be used without worrying that it failed in the middle of provisioning the necessary infrastructure.
