Secure Connection to Azure SQL Database

As a database administrator, I started my journey in deploying managed SQL databases on the cloud, and I highly recommend deploying Azure SQL.

Azure SQL belongs to the family of managed resources on the Azure cloud platform that runs the very familiar SQL Server engine. For most of these database resources, the Microsoft Azure platform takes care of the management, scalability, reliability, and performance recommendations. It also provides the underlying infrastructure to run the SQL Server database engine. Thus, the database administrator can focus on other aspects of work in the cloud.

Introduction to Azure Database Migration Service (ADMS)

Microsoft Azure platform provides an Azure Database Migration Service (ADMS) – a convenient solution for the Azure Cloud-based Databases migration tasks in a straight forward way. In this article, we elaborate on the AMDS essential work and integrated processes. 

We put in the focus issues related to the migration of object resources on Cloud to Cloud and on-premises database server to cloud. Also, we’ll deal with the cross-database migration compatibility between different database technologies.

Deploying a Database on Azure SQL

Introduction

Azure SQL Database is a Platform as a Service (PaaS) offered by Microsoft Azure. Hence, you need the Azure subscription to use this SQL Database. Azure offers new subscribers a free subscription and $200 worth of resources for 30 days. Recently I revived my relationship with MS Azure and explored the platform a little bit, using the Warner Chaves’ PluralSight Azure SQL Database for SQL Server DBAs training for the start.

In this article, I will explore the steps required to create an SQL Server in Azure and deploy a small database. Here I am using a free tier subscription, and the resources are on the basic level.  Further, I’ll explain these terms.

Basics of sys.dm_exec_requests

Performance monitoring and troubleshooting in SQL Server is a vast topic. In SQL Server 2005, dynamic management views, also known as DMV’s, have been introduced and became an essential helping tool for diagnosing SQL Server performance problems. At the same time, we can use dynamic management views for Azure SQL Database. Some of them can differ from SQL Server on-premise database but the logic of work is still the same. Microsoft has very good documentation about dynamic management views. The only thing,  you need to be careful about the version and product validation of dynamic management views. Read More

Migrating SQL Server Database to Azure SQL (PaaS)

In this article, we will highlight SQL Server Data migration to Azure SQL (PaaS).  You can find different approaches for this migration process because SQL Server offers different types of tools and features for this migration. Some of these are:

These migration approaches have some pros and cons. But if you ask my opinion, Data Migration Assistant is better than others because, in this migration process, you will face fewer migration problems or issues. Data Migration Assistant will be more helpful to handle these issues.

In this article, we will specifically mention Database Migration Assistant, also known as DMA. At the same time, we will make a small demo of SQL Server Management Studio Deployment Wizard.

Choosing Azure SQL Purchase Model and Service Tier

When we are beginning to think of migrating our on-premises databases to Azure SQL, we have to decide on a proper purchase model, a service tier, and a performance level. Before starting the Azure SQL migration process, we have to find logical and provable answers to the following questions:

  • Which purchase model is suitable for my apps and business requirements?
  • How much budget do I need?
  • Which performance level meets my requirements?
  • Can I achieve the acceptable performance of my apps?

Azure SQL Geo-Replication and Failover Groups

Azure SQL offers different types of business continuity solutions. One of these solutions is Geo-Replication that provides an asynchronous database copy. You can store this copy in the same or different data center locations (regions).  There can be four readable database copies. In the documentation of Microsoft notes, the recovery point objective (RPO is the maximum acceptable amount of data loss measured in time) is less than 5 seconds.  If we want to automate and make (users will not affect) failover mechanism transparent, we have to create the auto-failover group.

Getting Started with SQL Server 2017 on Linux in the Azure portal

SQL Server 2017 now is considered as a hybrid database enterprise solution as it expands its market and is ported to other operating system platforms. It also includes mainstream support for Linux machines. The Cloud makes the life of administrator much easier, now it’s no longer daunting task to configure the SQL Server instance. The easiest way to explore SQL Server on Linux is to provision a virtual machine through Microsoft Azure portal – portal.azure.com. The Linux azure virtual machine will come pre-configured with Linux and SQL Server 2017.
