Achieving Adequate Uptime for SQL Server in Kubernetes Means Thinking Outside the Pod

There is a reason why SQL Server isn’t exactly considered low-hanging fruit for Kubernetes containerization projects. The average SQL Server environment can be accurately described as nothing less than a “beast.” These environments can be massive in size and have a reputation for gobbling up much more than their fair share in budget dollars. Additionally, SQL Server environments:

  • Hold organizations’ most valuable data assets and require stringent security
  • Have critical uptime requirements, necessitating planned and unplanned downtime mitigation
  • Involve a high degree of management complexity with disparate OSes and infrastructure

Containers pose massive potential for significant gains in SQL Server agility, flexibility, cost-reduction, and more for organizations, but the uptime requirements of SQL Server workloads represent the critical bottleneck in the move to containerized deployments in Kubernetes.

Kubernetes Out-of-the-Box High Availability

As a standalone technology, Kubernetes does integrate some high availability functionality to help protect containerized SQL Server workloads. Built-in capabilities include pod replication, load balancing, service discovery, persistent volumes, and StatefulSets. These features allow Kubernetes to protect against things like:

  • Pod failure – Individual pods crashing due to resource contention issues or something else
  • Node failure – Anytime node becomes unavailable to cluster e.g. Hardware failure
  • Cluster failure ­– The loss of cluster communication capability e.g. Failure of control plane node

However, this is where an important distinction needs to be made—the distinction between high availability (HA) solutions that are ready to handle critical SQL Server workloads, and those that are not.

Kubernetes is a feature-rich container orchestration technology that has unlocked amazing possibilities for container-use in the IT industry, but when leveraged as a standalone HA solution, it cannot be considered a viable option for SQL Server workloads. This is predominantly due to the inherent latency associated with failover. By default, it takes Kubernetes five minutes to reschedule workloads from unreachable nodes. In 2023, this is not an acceptable failover baseline for SQL Server by any stretch of the mind. For the largest corporations, SQL Server downtime expense can reach well into the thousands of dollars per second, and settling for a 5-minute minimum downtime window for any failover is totally unacceptable.

So, while Kubernetes is the perfect technology for many container implementations, it does not have the chops to take on SQL Server high availability by itself. Fortunately, the surrounding technology ecosystem has evolved to bring integrated solutions to eliminate excessive downtime from SQL Server Kubernetes deployments.

High Availability Tailormade for SQL Server Containers

DxEnterprise (DxE) Smart High Availability Clustering software has been around for over a decade helping customers throughout the world ensure high availability for their mission-critical SQL Server environments. Now, what started as a solution for native SQL Server instances has been enhanced with industry-leading capabilities to unlock virtually zero downtime for SQL Server Kubernetes environments.

DxEnterprise takes Kubernetes cluster control to an even finer level of granularity—integrating health monitoring and failover automation at the database-level rather than the pod-level. In fact, DxEnterprise has been officially endorsed by Microsoft as the best approach to facilitating high availability for SQL Server in Kubernetes due to the powerful functionality it provides like:

  • Automatic failover for SQL Server Availability Groups in Kubernetes
  • Cross-site, cross-region, and cross-cloud Availability Group deployments
  • Boosted network performance through proprietary UDP tunnelling
  • Significantly reduced failover time from minutes to seconds
  • Ease of deployment using Rancher and/or Helm charts

This swath of DxEnterprise-derived enhancements helps add the secret sauce to Kubernetes to optimize high availability for even the most heavy-duty SQL Server environments. And the best part; it’s easier than ever to modernize your SQL Server with containers and unlock unparalleled cost-control, agility, and portability.

Ensuring AI Workload HA: SQL Server in K8s Made Reliable

Leveraging containerized stateful workloads such as Microsoft SQL Server to support AI applications is a practice that’s growing increasingly common. However, one of the primary conundrums in this scenario is enabling an adequate level of high availability (HA).

Container management solutions such as Kubernetes do a fantastic job letting you manage your containerized environments with increased agility and scalability, but out-of-the-box pod-level failover is grossly inadequate for the needs of enterprises and their SQL Server workloads. DH2i’s Don Boxley tells you about how software-defined perimeter technology and Smart HA software can solve this issue for good.

Breaking Barriers in Government IT – DH2i’s Solutions for Resilient Data and Fortified Security

In the ever-evolving landscape of the digital age, the role of government is undergoing a profound transformation. The traditional methods of governance are being reshaped by the power of digital technologies, giving rise to a new era of government modernization. In this blog, we delve into the importance of government modernization in the digital age and explore how embracing digital transformation can revolutionize public services, enhance citizen experiences, and drive societal progress. From improved efficiency and transparency to data-driven decision-making and cybersecurity, the benefits of government modernization are far-reaching and have the potential to reshape the way we govern and interact with public institutions.

The Complexities of Managing and Maintaining IT Infrastructure for Government Organizations

In today’s digital age, government organizations at various levels, ranging from local government to homeland security and remotely deployed branches of the military, heavily rely on robust and secure IT infrastructure to carry out their essential functions. However, the management and maintenance of this infrastructure come with a host of complexities, with data availability and security standing at the forefront.

Data Availability Challenges

Government organizations handle vast amounts of data critical to their operations, ranging from citizen records and public services information to classified intelligence and military operations data. Ensuring the availability of this data at all times is of utmost importance. However, it poses significant challenges due to factors such as system failures, natural disasters, cyber-attacks, and human errors. A single disruption in data availability can have severe consequences, leading to operational inefficiencies, compromised decision-making, and potential risks to public safety and national security.

Security Concerns

Data security is a paramount concern for government organizations, given the sensitive nature of the information they handle. Protecting classified data, personal citizen information, and critical infrastructure against unauthorized access, cyber-attacks, and data breaches is a constant battle in today’s increasingly interconnected world.

Likewise, compliance with regulatory frameworks, such as the General Data Protection Regulation (GDPR) and the Federal Information Security Management Act (FISMA), is essential to ensure the confidentiality, integrity, and availability of government data. However, this also adds another layer of complexity.

The challenges surrounding data availability and security are further amplified by the distributed nature of government organizations. From local government offices spread across multiple jurisdictions to remote military branches operating in challenging environments, ensuring consistent data availability and maintaining stringent security protocols across disparate locations is a complex undertaking. It requires implementing standardized procedures, establishing secure communication channels, and deploying monitoring and surveillance systems to detect and respond to potential threats promptly.
