Innehåll

Module 1: Intoduction to Azure Database Administrator
This module explores the role of a database administrator in the world of Azure SQL. It also provides some foundational information relevant to the overall content. This includes reviewing the various SQL Server-based options (SQL Server in a VM, SQL Managed Instance, and Azure SQL Database).

Module 2: Plan and Implement Data Platform ResourcesThis module introduces methods for deploying data platform resources in Azure SQL. You will learn about options for upgrading and migrating existing SQL databases to Azure. You will learn how to set up Azure resources to host SQL Server on a Virtual Machine; a SQL Managed Instance, and SQL Database. You will learn which options are best based on specific requirements, including the High Availability and Disaster Recovery (HADR) needs. They will learn to calculate resource requirements and understand hybrid approaches.

Module 3: Implement a Secure Environment for a Database Service
This module explores the practices of securing your SQL Server Database and an Azure SQL database. This includes reviewing the various SQL Server-based options and the various Azure options for securing Azure SQL Database. In addition, students will learn why security is crucial when working with databases and explain authentication options for Azure SQL Database.

Module 4: Monitor and Optimize Operational Resources
This module will teach you about resource optimization for your databases created using either IaaS or PaaS services. The module also covers monitoring server and hardware resources. It will familiarize you with the various tools available for monitoring performance and establishing a baseline. You will learn how to interpret performance metrics for the most critical resources. You will also learn how to troubleshoot database performance using Azure SQL Insights.

Module 5: Optimize Query Performance
Query execution plans are potentially the most critical aspect of database performance. Improving bad plans is certainly an area where a small amount of effort can bring huge improvements. While hardware issues can limit query performance, improving hardware usually yields performance improvements in the 10-20% range. More commonly, database administrators encounter queries that are not optimised, have stale or missing statistics, have missing indexes, or poor database design choices that lead to the database engine doing more work than is necessary to return results for a given query. Improving the plans can sometimes yield performance improvements in the 100-200% range or even more, meaning that after improving a plan with better indexes or statistics, a query could run twice or three times as fast! This module provides details on how to analyse individual query performance and determine where improvements can be made.

Module 6: Automation database tasks
A common goal for database administrators in many environments is to automate as many of their repetitive tasks. This can be as simple as scripting to automate a backup process and as complex as building a fully automated alerting system. This module provides details of automating tasks to simplify the DBA’s job. Methods include scheduling tasks for regular maintenance jobs, as well as how to use flexible jobs and Azure Automation runbooks.

Module 7: Plan and Implement a High Availability and Disaster recovery Solution

Data must be available when the business needs it. That means the solutions hosting the data must be designed with availability and recoverability in mind. For example, suppose you work for a company selling widgets in stores and online. Your main application uses a highly transactional database for orders. What would happen if the server or platform hosting the transactional database had a problem that made it unavailable or inaccessible for some reason? What impact would it have on the business? If the right solution is implemented, the database will come online reasonably with minimal effort, thus allowing business to continue with little-to-no impact. This module and its associated lab cover configuring, testing, and managing a solution for high availability and disaster recovery (HADR) in Azure for both Infrastructure-as-a-Service (IaaS) and Platform-as-a-Service (PaaS) deployments. This module will cover basic requirements and the various options available to achieve HADR.
