Scale Up for School: Unlock Secure and Robust Data Environments to Effortlessly Flex with User Demands

The new academic year has arrived, and a massive influx of users and data is imminent. Is your IT infrastructure ready?

For most educational institutions in the United States from K-12 to higher education, August is accompanied by the eventual start of the fall semester. This can be a stressful and trying time for IT teams working around the clock to make sure the network infrastructure is in place to sustain a massive spike in user traffic, and SQL Server databases have been scaled up to support inevitable growth.

When preparing for these action items, network security looms at the top of the priority list. Colleges, universities, and other education institutions have garnered an unfortunate reputation as being some of the most susceptible targets for ransomware and other cyberattacks. Like many other industries, education organizations possess a great deal of sensitive personal information. However, education industry organizations are uniquely sought after targets due to an unfortunate theme. They often have significantly underfunded cybersecurity departments. 

This blog will talk about:

  • Vulnerabilities of existing tech like VPN, and what new solutions can offer 
  • How education sector IT teams can pursue governmental cybersecurity funding 
  • SQL Server container tech that unlocks effortless scale-up while retaining HA 

Back in 2022, we published a blog imploring colleges and universities to start evaluating new networking technologies like software-defined perimeter (SDP) if they wanted to effectively secure their IT environments. Unfortunately, traditional solutions like virtual private networks (VPNs) are accompanied by some acute vulnerabilities in the scope of modern, cloud-based IT environments. For example, VPN: 

  • Represents a single access point with unlimited lateral attack surface 
  • Requires physical appliances that necessitate expensive, ongoing maintenance 
  • Physical boxes are a potential point of failure for the whole network to crash

SDP introduces highly available zero trust network access (ZTNA) tunnels that enable connections at the application level. This app-level connection takes away the excessive network access afforded by VPNs and eliminates lateral attack surface. Software-defined solutions also remove the need for any physical boxes, shrinking maintenance expenses significantly, and eradicating unnecessary points of failure in your network environment. 

SDP provides peak network security at the application level without the need for any physical infrastructure.

Software-defined perimeter provides peak network security across any platforms

Along with a detailed commentary on the cyberthreats facing colleges and universities today, our previous back to school blog points out several actionable best practices that are still just as relevant to IT teams today as they were in 2022. 

It’s important to note that the scope of this blog changes a bit. Virtual learning picked up a great deal of traction through the pandemic years, and much of that momentum has been retained across all facets of education whether it be actual classroom sessions, or virtual libraries containing personal information and learning resources. Resultantly, K-12 institutions are dealing with much of the same IT complexity and network security pressure as their higher education counterparts, but often with even more inadequate budgets. 

Fortunately, governmental awareness of these growing pressures on primary and secondary education institutions is growing, and new funding avenues are being introduced. 

Threats Facing K-12 Growing, Government Responding

The need to adopt new network security solutions has only grown more pressing in recent years, as 2023 is now regarded as “the worst ransomware year on record for the education sector.” Malwarebytes recently published a report citing a 105% increase in known ransomware attacks on K-12 and higher education from 2022-2023. 

In fact, network security pressure is growing so strong in K-12 environments that dedicated initiatives are being passed at the federal government level to help enhance cybersecurity efforts. One such effort is the launch of the Government Coordinating Council, an unprecedented effort to facilitate collaboration between federal, state, tribal, and local governments for the sole purpose of protecting K-12 schools from cybersecurity threats.

Grant Opportunities Are Growing to Mitigate Budget Shortcomings in K-12

It’s no secret that K12 public schools in the United States don’t generally have much wiggle room in their budgets. It is an especially unlikely thought to imagine a public school coming up with funding for a comprehensive cybersecurity defense plan. However, as threat levels have increased, and budgetary inadequacies have grown more pronounced, new supplementary funding opportunities have been established at all levels of government to help fuel the fight against cyberthreats. 

One significant example is the Federal Communication Commission’s Schools and Libraries Cybersecurity Pilot Program which was approved this past June. This program includes an allocation of $200 million with an intended goal to “Study and better understand what equipment, services, and tools will help protect school and library broadband networks from cyberthreats.” Ultimately, the results of this pilot program will be used to inform partners in all levels of government with actionable steps and best practices to tackle the growing cybersecurity threat most effectively. 

How Can K-12 Increase Chances of Securing Supplementary Funding

As of the writing of this blog, the application period has not been opened for the Schools and Libraries Cybersecurity Pilot Program in particular. This article provides some important details about that eventual application process. 

Speaking more generally though, there are a lot of things K-12 IT teams can do to put themselves in the best position to take advantage of future government grants and cybersecurity funding programs of this nature. The following checkboxes are a good place to start: 

  • Get thorough understanding of existing environment – Complete a comprehensive audit of current cybersecurity infrastructure and protocols to establish a detailed understanding of the most critical vulnerabilities and areas for improvement in your environment. 
  • Know EXACTLY how funds would be used – Create a specific, actionable plan (all the way down to specific solutions costs, # of licenses needed, etc.) on how you would use awarded funds if they were granted to your organization. 
  • Establish measurable goals – Create a list of measurable goals to track progress towards enhanced organizational cybersecurity. You want these goals to reflect your organization’s understanding of established industry best practices. 

Do you work at a K-12 institution and want a free tool to assess your organization’s current cybersecurity strategy? The Cybersecurity & Infrastructure Security Agency has created a free School Security Assessment Tool (SSAT) to see how your organization measures up with best practices, and even make recommendations on where and how to improve your overall approach.

Leverage SQL Server Container Technology for Easy Scale-Up

Along with critically necessary security enhancements, emerging SQL Server container technology also needs to be on the radar of IT professionals operating in this industry. Technologies like DH2i’s SQL Server Operator for Kubernetes provide a much easier way to flexibly scale with the wide-ranging demands put on education sector environments. 

Containers give organizations the ability to scale SQL Server in real time with demands.

SQL Server containers unlock unmatched scalability and resource utilization

DxOperator allows IT teams to spin up totally customizable, highly available SQL Server Availability Groups (AGs) in Kubernetes (K8s) in seconds. DH2i even provides the ability to create cross-platform hybrid AGs containing instances and containers – see it in this demo video.

In other words, you can take your organization’s most critical SQL Server workloads to a flexible, containerized environment without sacrificing any uptime. For the education sector, this means the agility to scale your SQL Server environment in real time to meet seasonal demand in a way that continually ensures optimal resource utilization. This means capturing cost savings and man-hours to distribute among other pressing needs at your organization like cybersecurity. 

Education industry IT teams have a great deal of responsibility on their plates all year, and especially this month as their userbase size explodes. Fortunately, governmental bodies and the greater information technology industry are evolving to meet these growing needs with: 

  • Software-defined perimeter software to replace vulnerable technologies like VPN 
  • Grant programs to help schools implement needed protections against cyberthreats 
  • SQL Server K8s solutions to simplify scaling with ever-changing industry demands

DxOperator by DH2i: Jumping the Hurdles to SQL Server Containers so You Don’t Have To

A perfectly scalable, streamlined paradise is on the horizon for your organization’s SQL Server environment if you’re pursuing containerization. This innovative technology promises unparalleled flexibility, portability, and never-before-achieved levels of resource/server utilization. While there are a lot of organizations diving head over heels into SQL Server containers, thousands of other organizations hold some serious reservations surrounding the idea.

So, why the hesitation to adopt technology that has proven itself an unambiguously positive enhancement to IT environments globally? 

It’s less a hesitation, and more so a realistic look at the hurdles that stand between your organization and the end goal of stateful SQL Server containers in production. It can be a long and seemingly insurmountable list. 

The Obstacles 

Many different barriers stand in the way of a successful container adoption initiative like: 

Skill Gap

Learning your way around container orchestration technologies like Kubernetes can be an incredibly foreign and complexity-riddled experience for even the most season IT pros, especially in organizations that have never delved into containerization before. 

Legacy Systems

SQL Server often powers complex and powerful applications that make up the backbone of your business, business tools that have been built from the ground up with all their unique dependencies, custom configurations, and compatibility issues. 

Stateful Nature

Containerizing stateful applications comes with the inherent complications of ensuring data persistence and having safe and efficient backup/recovery solutions in place. 

Stringent Performance Requirements

Databases require incredibly consistent performance, and the introduction of container orchestration technology can have an unfavorable impact on performance if not done with great care and attention to detail.

Licensing Costs

If not managed closely, SQL Server licensing can be incredibly convoluted when you introduce containers into the typical physical or virtual core licensing framework and lead to unexpected costs. 

Security Concerns

Database workloads necessitate an intense commitment to security as they often house sensitive information. Ensuring proper isolation and access controls with containerized SQL Server can be challenging. 

DH2i’s Path to Enablement 

Ever since Microsoft’s first dive into Linux and containers with SQL Server 2017, DH2i’s DxEnterprise Smart High Availability Clustering software has remained at the forefront of this technology providing all the high availability capabilities that organizations needed to integrate containers into their SQL Server environments such as: 

  • Fully automatic failover for SQL Server AGs in K8s to ensure minimum downtime 
  • The ability to create mixed SQL Server clusters containing instances and containers 
  • Infrastructure agnostic ZTNA tunnels to securely connect any native or containerized workloads 

Cluster SQL Server instances and containers side by side in the same Availability Group.

DH2i DxEnterprise allows organizations to unify all of their SQL Server on Windows, Linux, and Kubernetes side-by-side in the same highly available cluster.

However, after identifying the slew of hurdles preventing organizations from making the move to SQL Server container modernization, it became abundantly clear that DH2i’s efforts also needed to be directed to streamlining/enabling the adoption of container technology, not just optimizing the high availability and management experience. 

The release of DxOperator by DH2i entirely changed the game in February of 2024. This technology is an included feature of DxEnterprise software and has earned the title of Microsoft’s preferred SQL Server Operator for Kubernetes (check out this MS tutorial for AKS deployment). When paired with other technologies like Rancher Prime by SUSE, this solution stack has unequivocally paved the most straightforward and efficient path to SQL Server Availability Group deployments in Kubernetes, helping mitigate many of the obstacles listed above.  

Overcoming Deployment Obstacles 

Skill Gap 

DxOperator by DH2i and Rancher Prime by SUSE work together seamlessly to create a drastically simplified deployment and management experience for IT pros without previous Kubernetes experience. 

Rancher Prime is a comprehensive management platform that provides an intuitive point and click UI that makes it easy to view custom parameter descriptions and make modifications, rather than having to learn the ins and outs of a totally foreign Kubernetes command-line and make manipulations directly. Rancher Prime also provides unified policy, security, and user management to simplify the orchestration of increasingly complex clusters. 

DxOperator by DH2i is deployable straight from the Rancher Application Catalog and totally automates the deployment of your SQL Server AG in Kubernetes. Deployment becomes as simple as specifying your desired cluster characteristic (# of replicas, async or sync, built-in load-balancer, etc.) and executing a short, minutes-long deployment. 

Legacy Systems  

DH2i DxEnterprise software makes migrating from legacy SQL Server systems to new systems as easy and quick as a failover.  DxEnterprise is able to do this because it is the only “Smart” HA clustering solution that can support mixed clusters containing Windows, Linux and containers, independent of the infrastructure those systems are running on. 

Stateful Nature  

DH2i software integrates containerized SQL Server workloads into the DxEnterprise HA clustering framework which supports any storage that is SCSI-3 Persistent Reservation compliant. From there, ensuring data persistence is a simple task, and DxEnterprise clusters can be easily stretch to provide dependable disaster recovery automation across different availability zones, subnets, and regions. 

Stringent Performance Requirements 

DH2i’s DxEnterprise doesn’t just function as an HA solution to failover workloads when their host server goes down. Users of the software can easily set specific performance thresholds at the workload level to ensure applications are always running in their best execution venues. If another host OS provides a better option to keep the workload performant and meet SLAs, the instance or container can be easily failed over in seconds at the speed of an application stop-start. 

Licensing Costs 

DH2i’s high availability clustering framework allows organizations to safely and sustainably stack multiple containerized SQL Server instances and containers on servers to maximize resource utilization. DH2i customers have often been able to save up to 60% in licensing costs (inclusive of DxEnterprise cost) and reduce OS counts by 8-15x through consolidation initiatives. In-turn, the reduction in server overhead contributes to additional savings in the form of maintenance/management costs.  

Security Concerns 

Rancher Prime’s built-in security functionality is further bolstered by integration with other infrastructure agnostic software solutions like NeuVector Prime for full container lifecycle security. Combined with the application-level zero trust network access tunnels of DH2i, containerized deployments can be protected with the same mission-critical attention to security afforded in traditional SQL Server deployments. 

Using zero trust network access tunnels, users can securely connect any server, anywhere.

DH2i’s built in software-defined perimeter capability allows users to securely connect any server, anywhere, with application-level ZTNA tunnels.

Conclusion 

DH2i has supported SQL Server containers in Linux for years at this point—providing all the necessary capabilities to ensure nearest-to-zero downtime and facilitate high availability management once you’ve deployed SQL Server containers within your organization. 

The release of DxOperator by DH2i represents an added focus to enabling organizations to actually adopt SQL Server containers in the first place. This SQL Server Operator for Kubernetes from DH2i, along with powerful integrations with solutions like Rancher Prime by SUSE, have combined to systematically overcome the challenges of stateful container deployment at your organization. Incredibly easy, UI-based management and advanced automation have paved the easiest path ever into container deployment, and DH2i’s clustering framework ensures the industry’s lowest possible downtime for SQL Server containers.
