In this episode of Data Driven, Swapnil Bhartiya sits down with Margaret Hoagland, VP of Global Sales & Marketing at SIOS Technology, to explore the pressing issue of patch management in mission-critical IT environments. With cybersecurity threats rising and regulatory pressures mounting, applying patches promptly without impacting uptime has become a formidable challenge for enterprises.

Margaret unpacks how high availability (HA) clustering, particularly through SIOS LifeKeeper, is transforming the patch management landscape. She explains that traditional patching workflows often introduce unacceptable levels of downtime, putting sensitive systems at risk of breach or non-compliance. High availability clustering mitigates this by enabling a “rolling update” approach—where patches are applied and tested on a secondary node before seamless failover to production. This method ensures minimal disruption and zero service downtime.

She also highlights the relevance of HA for heavily regulated sectors such as healthcare, financial services, and manufacturing, where systems like electronic health records or trading platforms must remain online 24/7. Margaret offers practical advice for IT teams: start small by downloading a free trial of SIOS software and experiment with a two-node cluster to see the benefits firsthand.

If your business values uptime, security, and compliance, this interview is a must-watch.

Transcript
Swapnil Bhartiya: Patch management without downtime is the holy grail for mission-critical environments. Margaret, can you explain why patching is still so challenging?

Margaret Hoagland: Sure. Patch management is when OS or app vendors release updates—often for security vulnerabilities. The challenge is testing those patches in a realistic production environment without causing downtime. That delay can leave systems exposed to zero-day attacks.

Swapnil Bhartiya: What are the risks if teams delay patching?

Margaret Hoagland: You’re risking application downtime or critical system failures. Any change to infrastructure—OS, network, storage—can cause problems. If you haven’t thoroughly tested, you could have an incident at the worst time.

Swapnil Bhartiya: How does high availability clustering solve this?

Margaret Hoagland: With a solution like SIOS LifeKeeper, apps run on a primary node while a passive secondary stands by. Patches are applied to the passive node, tested, and then systems failover. No user disruption, no service downtime.

Swapnil Bhartiya: Which industries benefit most?

Margaret Hoagland: Healthcare, financial services, and manufacturing—places with low downtime tolerance. For example, hospitals can’t afford to take systems offline even for planned maintenance.

Swapnil Bhartiya: How does this help with compliance?

Margaret Hoagland: Regulations like HIPAA and SOX demand timely patching and security. HA clustering ensures quick updates without compromising operational uptime.

Swapnil Bhartiya: Any practical advice for teams considering this?

Margaret Hoagland: Yes, start with a free trial of our clustering software. We can help set up a two-node cluster so teams can see the benefit firsthand.
