SQL Server High Availability

Learn how ABCloudz can help you meet SQL Server high availability and disaster recovery requirements for your applications.

Typical challenges that we see

Our team of certified professionals helped hundreds of our customers build SQL Server high availability and disaster recovery solutions. Over the years, we’ve established a proven approach, which allows for creating exemplary HA and DR solutions without sacrificing database performance. During this same time, our team has faced the following challenges and discovered the solutions and workarounds.




Improving the automatic failover configuration

Is an existing failover solution reliable and cost-effective? How can I make the most out of the Always On availability groups?

The ABCloudz database experts know that there is always space for improvement. All solutions have pros and cons — be it the cost, complexity, or lack of automation. We can perform the SQL Server Failover Health Check and provide you with the report, which helps pick the right modernization option for you.

On the one hand, you may want to add or remove nodes from your existing failover cluster instances to improve the overall system’s performance or reduce maintenance costs. On the other hand, you may decide to configure your solution in such a way to guarantee that it meets the permitted downtime. The choice is yours — the implementation is on ABCloudz.

Providing with alternative failover solutions

How can I improve reliability and maximize the availability of my SQL Server systems?

Since 2017, SQL Server can run on Linux. Therefore, you may consider using multiple node failover clustering on Windows and Linux for your SQL Server workloads.

However, with the cloud services gaining ground, you may want to use a simple failover set up in the Azure cloud rather than complex SQL Server code to handle failover scenarios. Finally, we can help you make use of the Snowflake cloud data platform with eleven 9’s of durability SLA.

Providing for disaster recovery

How can I make my products always available to customers?

Once we spot and reserve the most crucial data, we organize the SQL Server disaster recovery process. By properly setting up availability groups, copying techniques, and other methods, we ensure your data is always running under any circumstances with automated failover that keeps your data intact.

Disaster immunity for your critical business infrastructure

SQL Server offers many technologies which can be used to minimize downtime and maximize data protection. These technologies allow businesses to ensure smooth operation, continuous access to business-critical data, and meet availability levels in accordance with certain service level agreements.

The following SQL Server high availability solutions mask the effects of a hardware or software failure and maintain an availability of applications such as:

  • Availability groups
  • Failover clustering
  • Database mirroring
  • Log shipping

Getting started

We start with thorough testing of your existing SQL Server HA and DR solutions. At this point, we discover vulnerabilities and optimization opportunities while you have a chance to see what a system failure will do to your applications.

Action plan and implementations

Our Principal SQL Server Solution Architects provide you with a health check report. It may include critical issues, needed to be addressed instantly, as well as modernization options, which will improve your existing solution.

After discussing these modernization options with you, ABCloudz then goes further and provides you with the human power required for the implementation of these changes.

Results and benefits

Now you can rest assured that your SQL Server database environment is safe and secure.

Finally, our SQL Server health check helps assess the migration to the cloud path. This approach will improve your failover capabilities as well as the application’s performance.

Case study: developing an Always On availability group

One of the largest transportation authorities was running their mission-critical system on a SQL Server platform. Any downtime would negatively affect their business substantially.

The company decided to modernize their system and implement high availability and disaster recovery solutions. This approach allows for keeping their system running without interruptions. To meet the customer’s needs, we engaged in a technical support role and delivered detailed instructions. We also created automated scripts to implement the highly available architecture in compliance with Always On Availability Group checklists. Our solution allowed the customer to build a perfectly configured and highly available system by themselves. At the end of the day, our customer saved on configuration time and money.
