DP-200: Implementing Azure Data Solution Exam Preparation

Microsoft Azure (formerly Windows Azure) is a cloud computing service created by Microsoft for building, testing, deploying, and managing applications and services through Microsoft-managed data centers.

Azure Provides Three services:

1. software as a service (SaaS),

2. platform as a service (PaaS).

3. infrastructure as a service (IaaS)

Azure supports many different programming languages, tools, and frameworks, including both Microsoft-specific and third-party software and systems. Azure was announced in October 2008, started with the codename "Project Red Dog", and released on February 1, 2010, as "Windows Azure" before being renamed "Microsoft Azure" on March 25, 2014.

Candidates for Exam DP-200: Implementing an Azure Data Solution are Microsoft Azure data engineers who identify business requirements and implement proper data solutions that use Azure data services like Azure SQL Database, Azure Cosmos DB, Azure Data Factory, Azure Databricks, Azure data warehouse (Azure Synapse Analytics)

This course covers, how to provisioning data storage services like Azure SQL, Storage account, Data lakes. In the Azure Data factory section, we cover how to transform your data, identifying performance bottlenecks, and accessing external data sources including on-premise SQL server and file systems.

Azure Data Factory (ADF):

The Azure Data Factory service is a fully managed service for composing data storage, processing, and movement services into streamlined, scalable, and reliable data production pipelines. The Azure Data Factory (ADF) is a service designed to allow developers to integrate disparate data sources. ADF or Azure Data Factory is a platform somewhat like SSIS or Alteryx in the Azure environment to manage the data you have both on-prem and in the cloud.

It provides access to on-premises data with the help of a software. By using this link we could connect to the on-premise file system as well as to on-premise SQL databases. From Azure Data Factory, you could access almost all azure services without any difficulties.

Access to on-premises data is provided through a data management gateway that connects to on-premises SQL Server databases and we will show you how to install this software and how to connect your on-premises environment with Azure cloud.

If you ever created any data transfer activities in Azure, or in SSIS, you will find it a similar tool. If you use ADF, you could focus on your data—the serverless integration service does the rest.

• and many more (with real-life scenarios). Check out our course descriptions for updated information.

SQL Database -Cloud Database as a Service:

Azure SQL Database is a fully managed relational database with built-in intelligence supporting self-driving features such as performance tuning and threat alerts. According to Wiki, Microsoft Azure SQL Database is a managed cloud database provided as part of Microsoft Azure. A cloud database is a database that runs on a cloud computing platform, and access to it is provided as a service. Managed database services take care of scalability, backup, and high availability of the database.

Azure SQL Database: Azure SQL Database is a relational database-as-a-service (DBaaS) based on the latest stable version of Microsoft SQL Server. It is a fully managed Platform as a Service (PaaS) Database Engine that handles most of the database management functions such as upgrading, patching, backups, and monitoring without user involvement.

In this course, we will show you how to launch the Azure SQL database in five minutes, with and without sample data.  We will show you, how to use SQL elastic pools.

Elastic pools help you manage and scale multiple Azure SQL databases. According to Azure documentation, SQL Database elastic pools are a simple, cost-effective solution for managing and scaling multiple databases that have varying and unpredictable usage demands. With an elastic pool, you determine the amount of resources that the elastic pool requires to handle the workload of its databases, and the amount of resources for each pooled database.

Azure SQL Database is always running on the latest stable version of the SQL Server Database Engine and patched OS with 99.99% availability.

The databases in an elastic pool are on a single Azure SQL Database server and share a set number of resources at a set price. By the end of this course, you will have a clear idea about how to configure SQL elastic pool.

Geo-Replication:

Active geo-replication is an Azure SQL Database feature that allows you to create readable secondary databases of individual databases on a SQL Database server in the same or different data center (region). We will show you how you could configure a Geo-replication and force failover to the secondary database manually.

Azure Cosmos DB:

Azure Cosmos DB is Microsoft's globally distributed, multi-model database service. With a click of a button, Cosmos DB enables you to elastically and independently scale throughput and storage across any number of Azure regions worldwide. In our course, we will see.

• How you could create a cosmos DB account,

• How to Create Databases inside your cosmosDB account

• How to insert data into CosmsoDB containers.

• How to Restive data that you saved in cosmos DB tables or containers by using SQL

Introduction to Azure Storage:

Azure Storage is Microsoft's cloud storage solution for modern data storage scenarios. Azure Storage offers a massively scalable object store for data objects, a file system service for the cloud, a messaging store for reliable messaging, and a NoSQL store.

In this course, we will cover how to create a storage account, how to create containers and file systems and how to upload data into these services and how to access these storage services from different azure data solutions services like data factory, data bricks, and SQL databases.

Azure Data Lake Storage:

Azure Data Lake Storage, is a fully-managed, elastic, scalable, and secure file system that supports HDFS semantics and works with the Hadoop ecosystem. ‎Azure Data Lake Storage Gen2 is a set of capabilities dedicated to big data analytics, built on Azure Blob storage. Data Lake Storage Gen2 is the result of converging the capabilities of our two existing storage services, Azure Blob storage and Azure Data Lake Storage Gen1.

In this course we will see, how to create data lakes, How to move CSV data from azure blob storage to azure data lake using azure data factory. How to read your data (Azure Data lake) using azure Databricks.

Azure Databricks:

Azure Databricks provides the latest versions of Apache Spark and allows you to seamlessly integrate with open source libraries. Spin up clusters and build Bigdata applications. According to Databricks documents, Azure Databricks is a fast, easy, and collaborative Apache Spark™ based analytics platform optimized for Azure. Azure Databricks supports Python, Scala, R, Java, and SQL, as well as data science frameworks and libraries including TensorFlow, PyTorch, and scikit-learn.

In this course, we will show you how to configure Azure Data bricks, How to launch a cluster, how to create notebooks.

Azure Synapse Analytics (Azure SQL Data Warehouse):

Azure Synapse is a limitless analytics service that brings together enterprise data warehousing and Big Data analytics. Azure Synapse is Azure SQL Data Warehouse evolved. In this course, you will learn how to create an Azure SQL pool, access a data lake storage account (how to use PolyBase external tables to load data from Azure Data Lake Storage).
