Microsoft released PowerApps to a selective audience as a private preview in November 2015. It’s a service for enterprises to connect data across clouds to create intelligent business apps faster than ever before and share them to any device. Besides addressing the business developer and power user, it also provides opportunities for developers. This enables enterprises to expose corporate internal sources to be used within PowerApps and unleash the power of PowerApps combined with internal data sources. This session goes into the details of the possibilities for developers to leverage the Azure App Services and build APIs to use within your PowerApps. Live demos cover building and managing the API which exposes the internal data within a PowerApp on your device.

- Developing customer software to if often privileged for a handful of business apps, as building customer applications to meet enterprise requirement has its own challenges : Time consuming : developing of a customer mobile app can take anywhere from 3 to 12 months for a single project, depending on the app complexity (source ADT magazine). This becomes challenging in situation where LOB wants to respond and implement improvements quickly Cost prohibitive : driven by a shortage of specialized resourcing : 94% of the enterprise organization have a shortage of App developers, as a lot of App developers still prioritize consumer facing Apps (Source ADT Magazine & Vision Mobile). 180K first time development, changes and iterations Off-the-shelf SaaS can only solve so many problems Most ‘off-the-shelf’ SaaS solutions are targeted as solving specific problems` and often come with their own mobile App. These apps provide a mobilize experience of these specific SaaS solutions. However, the onslaught of information from these individual often disconnected SaaS services will virtually make it impossible for workers to follow everyday business processes. More and more business process will span multiple applications and SaaS services. (Source: eWeek)
- When building Line-of-business applications there two different requirements sets that need to be addressed, but can often cause friction between. On one side, requirements set by IT organizations on: Security - for example Apps can only provide access to the line-of-business data the person is entitled to given their role in the organization. Scalability - ensuring the applications can be use by a large enough number of people in a performant way. Managed - making sure application updates can be easily distributed, for example not dependent on an OS-related AppStore Integrated - To reach their full power, Apps need to use existing data sources and systems and can't live in isolation Compliant - the app need to follow any policy compliancy guidance set by the organization While on the other side the line-of- business sets requirement around: Fast - speed at which a new application can be built to meet the minimal requirements from business. There is no time to wait 6-12 month for a new app to be available Iterative - how quickly and easily can iterations be implemented? Eg business processes continuously change, line-of-business apps need to be able to keep up with these changes through quick iterations Cross-platform - applications been to be used on the devices and platforms of our choosing Beautiful - consumerization of IT set increased requirements on the look and feel of Apps, as users transpose their experience of their consumer apps onto enterprise apps. Easy - easy to use application that do not need any end-user training In the past, these two sets of requirement often conflicted with each other and have kept companies back in innovation and speed of business.

- Power Suite / Power Tier: Power BI + PowerApps + Flow Common Data Model Security Model: who can access the data based on roles, who can add, modify data Real time sync: get data into the platform from both cloud services and on-premises data (gateways) Operational Data Store: automatically create the operational data store to use in Azure Analytics (Power BI) Data API: pro development tools based on SDK
- An operational data store (or "ODS") is a database designed to integrate data from multiple sources for additional operations on the data.
- The Azure API App project template is equivalent to choosing the Empty ASP.NET 4.5.2 template, clicking the check box to add Web API support, and installing the Swashbuckle NuGet package. In addition, the template adds some Swashbuckle configuration code designed to prevent the creation of duplicate Swagger operation IDs. Once you've created an API App project, you can deploy it to an API app the same way you saw in this tutorial. https://azure.microsoft.com/en-us/documentation/articles/app-service-api-dotnet-get-started/
