When you browse to a webpage, the web server communicates with your browser by using HTML, CSS, and JavaScript. For example, If you interact with the page by submitting a sign-in form or selecting a buy button, the browser sends the information back to the web server.

In a similar way, web servers can communicate with a broad range of clients (browsers, mobile devices, other web servers, and more) by using web services. API clients communicate with the server over HTTP, and the two exchange information by using a data format such as JSON or XML. APIs are often used in single-page applications (SPAs) that perform most of the user-interface logic in a web browser. Communication with the web server primarily happens through web APIs.

The building blocks of Power BI are semantic models and visualizations. Create a semantic model and then use visuals to build a report. Let’s explore these items in more detail and how they relate to the flow of Power BI.

Create a semantic model

A semantic model consists of all connected data, transformations, relationships, and calculations. To follow the flow of Power BI, you first connect to data, transform data, and create relationships and calculations to create a semantic model.

First, connect to as many data sources you need. Then clean and transform the data to your needs, using Power Query Editor. Add relationships between tables and calculations to extend the semantic model. After all of that, now you can create a report.

Create visualizations in a report

In Power BI Desktop, when you create a visualization (also called visual), you add it to the canvas for a report page. Choose your visualizations to build pages in your report. It’s ideal to keep each page simple with related data, so consumers can easily see the insights.

Power BI is a low-code solution, which means that you can “drag and drop” data field directly onto the canvas. Power BI will choose a visual for your data field. You can easily change between visuals for the same fields, and add or remove data fields to the visual.

One of the most valuable features of Power BI reports is the interactivity between visuals. Consumers can select different data points in the visual and see how that affects the other visuals. Depending on your design, they can also drillthrough from one visual to more detail or filter based on different fields in the report.

Software as a service (SaaS) is the most complete cloud service model from a product perspective. With SaaS, you’re essentially renting or using a fully developed application. Email, financial software, messaging applications, and connectivity software are all common examples of a SaaS implementation.

While the SaaS model may be the least flexible, it’s also the easiest to get up and running. It requires the least amount of technical knowledge or expertise to fully employ.

Shared responsibility model

The shared responsibility model applies to all the cloud service types. SaaS is the model that places the most responsibility with the cloud provider and the least responsibility with the user. In a SaaS environment you’re responsible for the data that you put into the system, the devices that you allow to connect to the system, and the users that have access. Nearly everything else falls to the cloud provider. The cloud provider is responsible for physical security of the datacenters, power, network connectivity, and application development and patching.

Platform as a service (PaaS) is a middle ground between renting space in a datacenter (infrastructure as a service) and paying for a complete and deployed solution (software as a service). In a PaaS environment, the cloud provider maintains the physical infrastructure, physical security, and connection to the internet. They also maintain the operating systems, middleware, development tools, and business intelligence services that make up a cloud solution. In a PaaS scenario, you don’t have to worry about the licensing or patching for operating systems and databases.

PaaS is well suited to provide a complete development environment without the headache of maintaining all the development infrastructure.

Shared responsibility model

The shared responsibility model applies to all the cloud service types. PaaS splits the responsibility between you and the cloud provider. The cloud provider is responsible for maintaining the physical infrastructure and its access to the internet, just like in IaaS. In the PaaS model, the cloud provider will also maintain the operating systems, databases, and development tools. Think of PaaS like using a domain joined machine: IT maintains the device with regular updates, patches, and refreshes.

Depending on the configuration, you or the cloud provider may be responsible for networking settings and connectivity within your cloud environment, network and application security, and the directory infrastructure.

Infrastructure as a service (IaaS) is the most flexible category of cloud services, as it provides you the maximum amount of control for your cloud resources. In an IaaS model, the cloud provider is responsible for maintaining the hardware, network connectivity (to the internet), and physical security. You’re responsible for everything else: operating system installation, configuration, and maintenance; network configuration; database and storage configuration; and so on. With IaaS, you’re essentially renting the hardware in a cloud datacenter, but what you do with that hardware is up to you.

Shared responsibility model

The shared responsibility model applies to all the cloud service types. IaaS places the largest share of responsibility with you. The cloud provider is responsible for maintaining the physical infrastructure and its access to the internet. You’re responsible for installation and configuration, patching and updates, and security.
