💥 Imagine waking up to find your company’s entire website - gone. Not broken. Not down. Completely deleted. That’s exactly what happened to someone I was referred to this weekend. They’d hired a developer off Upwork to “upgrade” their site. During the deployment, the developer accidentally deleted and replaced the entire cPanel instance - file system and database. No backups. No version control. Nothing. When I got the call, I dug into their hosting environment, found a few stray artifacts, and started coordinating directly with the hosting provider’s disaster recovery team. Hours later, we got lucky - they had internal backups we could recover. 💡 Lesson learned: Hire experts who know how to protect your systems before something goes wrong. And if you’re building or running software professionally, take a page from SOC 2 compliance. Under the “Availability” principle, companies must have: - Verified backup and recovery procedures - Documented vendor management - Clear contingency plans when systems fail I’ve helped multiple companies achieve SOC 2 compliance, and this is exactly why it exists - to make sure “total loss” never happens in the first place. ✅ Know who your vendors are. ✅ Ask how often they back up. ✅ And never rely on hope as your recovery plan.

Cloud Disaster Recovery in Azure What Actually Matters Before choosing any DR pattern, align on two non-negotiables: 1. RTO (Recovery Time Objective) Maximum acceptable service downtime before business impact becomes critical. 2. RPO (Recovery Point Objective) Maximum acceptable data loss window - how far back you can afford to recover. These two define everything: architecture, cost, and operational complexity. Azure Disaster Recovery Patterns 1. Backup & Restore (Baseline Resilience) This is the minimum viable DR strategy. You rely on backups stored in services like Azure Backup or Azure Blob Storage (RA-GRS), and rebuild infrastructure during recovery (often using IaC like Bicep/Terraform). Azure-native stack: Azure Backup (VMs, SQL, SAP HANA) Azure Site Recovery (for backup + orchestration scenarios) Immutable vaults for ransomware protection Typical profile: RTO: Hours → Days RPO: Backup frequency dependent (e.g., 4–24h) Best for: Non-critical workloads, cost-sensitive environments, dev/test 2. Pilot Light (Minimal Always-On Core) You keep critical components running (identity, networking, minimal app tier), while the rest is provisioned on-demand during failover. Think: “just enough infrastructure to ignite recovery.” Azure-native approach: Pre-configured VNet, NSGs, Azure AD integration Azure SQL / Cosmos DB geo-replication enabled Compute scaled to near-zero (VMSS / App Service) Typical profile: RTO: ~15 mins → few hours RPO: Minutes to hours (depends on replication) Best for: Apps that need faster recovery but not full real-time redundancy 3. Warm Standby (Active-Passive Ready State) A fully deployable secondary environment is already running at reduced capacity, continuously synced with production. Failover = scale up + switch traffic. Azure-native design: Azure Site Recovery (VM replication across regions) Azure SQL Active Geo-Replication / Failover Groups Azure Traffic Manager or Front Door for failover routing Typical profile: RTO: Minutes → ~1 hour RPO: Seconds → minutes Best for: Business-critical systems where downtime = revenue loss 4. Hot / Active-Active (Multi-Region Resilience) Both regions are live and serving traffic simultaneously. No “failover” in the traditional sense , just traffic redistribution. This is where cloud-native design shines. Azure-native architecture: Azure Front Door (global load balancing + health probes) Multi-region App Services / AKS clusters Cosmos DB multi-region writes or SQL geo-replication Event-driven sync (Event Grid / Service Bus) Typical profile: RTO: Near-zero RPO: Near-zero (seconds or less) Best for: Mission-critical, global applications (finance, SaaS platforms) Tight budget → Backup & Restore Moderate criticality → Pilot Light High business impact → Warm Standby Zero downtime requirement → Active-Active If you're designing on Azure today, DR is not optional , it's architecture. Consider a Repost if this is useful.

The July 2024 CrowdStrike incident, which resulted in widespread IT disruptions, provides several important lessons for organizations relying on third-party software and services: 1. Robust Software Release Processes: The incident underscores the critical need for stringent testing and validation in software updates, particularly for security software. The failure in CrowdStrike’s update process led to severe disruptions across various industries, demonstrating the importance of comprehensive testing, integrity verification, and staged rollouts before deploying updates at scale. 2. Vendor and Third-Party Management: This event highlighted the risks inherent in relying on external vendors for critical IT infrastructure. A thorough Business Impact Analysis (BIA) should identify dependencies on third-party services and develop strategies to mitigate potential disruptions. Regular audits and risk assessments of third-party providers are crucial to prevent similar incidents. 3. Incident Response and Business Continuity Planning: The need for well-developed and regularly tested incident response and business continuity plans was made evident. Organizations must be prepared for unexpected failures, including those caused by essential security tools, and should maintain up-to-date playbooks for various disaster scenarios. 4. Key Management and Data Recovery: The incident also emphasized the importance of proper key management, especially in encrypted environments. Many organizations struggled to recover data because of inadequate key management, highlighting the need for robust systems to manage and retrieve encryption keys during crises. 5. Global IT Infrastructure Resilience: The incident serves as a reminder of the fragility of our interconnected IT systems. Diversifying vendors, implementing distributed decision-making, and ensuring redundancy in critical systems can help build a more resilient global IT infrastructure.

On July 19, 2024, a single faulty update from CrowdStrike caused a global IT outage, affecting airlines, banks, and hospitals worldwide. This incident underscores the critical need for robust vendor risk management and procurement strategies. As a procurement and supply management professional, you understand that vendor risks can have devastating consequences. Here are some lessons from the CrowdStrike incident to help mitigate risks and enhance organizational resilience: Vendor Selection: - Don’t just choose a vendor – evaluate their software development processes, testing procedures, and incident response capabilities. Ensure they can meet your business needs effectively. Contractual Safeguards: - Make sure your contracts include clauses that hold vendors accountable for faulty updates or outages. Outline penalties and service level agreements (SLAs) to ensure business continuity during disruptions. Performance Monitoring: - Keep a close eye on vendor performance by tracking metrics like uptime and response times. Identify potential issues early on and take corrective action before they become major problems. Diversification: - Don’t put all your eggs in one basket! Diversify your cybersecurity vendors to reduce reliance on a single source and minimize the impact of future outages. Rigorous Testing: - Thorough testing of updates in various environments is crucial to prevent widespread disruptions. Don’t skip this step! Vendor Collaboration: - Open communication between vendors, IT professionals, and end-users is essential for managing and mitigating potential issues. Build strong relationships with your vendors. Backup and Redundancy: - Organizations must have robust backup systems and redundancy plans to maintain operations during IT failures. Don’t get caught off guard! Cloud Management: - Cloud-based solutions can offer greater scalability and resilience compared to on-premise infrastructure. Consider migrating to the cloud to enhance your organization’s agility.

🛡️ Disaster recovery in Azure: the hard part isn’t failover, it’s the design choices before it A lot of Azure DR discussions start with: “Which secondary region should we choose?” But this article is a good reminder that disaster recovery is not just a region decision. It’s a business + architecture decision that needs to balance RTO/RPO, compliance, latency, service availability, capacity, cost, and operational readiness.  ✅ Classify applications first Not every workload needs the same DR pattern. Business criticality, dependencies, data sensitivity, and recovery requirements should drive the design.  ✅ Region selection is multi-dimensional The “best” DR region is not always the cheapest or closest one. You need to weigh service parity, SKU availability, latency, capacity stability, risk diversification, and compliance.  ✅ Region pairing is not the answer by itself The article calls out an important point: Azure does not automatically fail over your applications across regions, and region pairs do not provide automatic app failover. Customers still need to design replication, failover orchestration, and recovery mechanisms.  ✅ Testing is part of the strategy Application-level validation, latency benchmarking, capacity confirmation, runbooks, and regular DR drills are what turn a design into something you can actually trust in production.  One more detail many teams miss: Log Analytics data doesn’t directly migrate between workspaces, so recovery plans may also require reconfiguring diagnostic settings in the target setup.  Good read for anyone working on resilient Azure platforms and enterprise workload design https://lnkd.in/gpp5F6An 👉 Worth saving for your next resilience or landing zone review. #Azure #AzureTipOfTheDay #AzureMissionCritical #MSAdvocate #DisasterRecovery #BusinessContinuity #CloudArchitecture #SRE #AzureInfrastructure #Reliability

I hope none of your travel plans were disrupted by the airport chaos this weekend in Europe. The Collins Aerospace cyberattack that shut down check-in systems across Europe revealed something most executives ignore: your operations depend entirely on systems you don't control. Friday night, hackers compromised Collins Aerospace's MUSE software - the check-in and boarding system used by major airports across Europe. By Saturday morning, Heathrow, Brussels, Berlin, and Dublin were down to manual check-in only. Flight cancellations. Thousands stranded. Brussels canceled 50% of Sunday departures. One vendor. One piece of software. Multiple countries paralyzed. This wasn't an attack on your infrastructure. It was an attack on someone else's infrastructure that you depend on to operate. If it happened to Europe's busiest airports, it can happen to you. The companies affected had security measures, disaster recovery plans, and qualified IT teams. They still went down. You can't insure against chaos. You can only prepare for it. Can your team execute manual procedures under pressure, or do they just exist in a document nobody's opened since 2019? How many hours (not days) until you're operational again if your primary vendor goes dark? The difference between companies that survive vendor failures and those that don't: they treat preparation like operations, not like paperwork. Quarterly vendor failure drills. Hybrid capabilities that work when digital fails. Disaster recovery tested as rigorously as quarterly audits. Every company on shared infrastructure - airports, hotels, logistics, transportation - is one vendor compromise away from paralysis. The question isn't whether your vendor will be attacked. It's whether you'll still be operating when they are. #CyberSecurity #DisasterRecovery #TravelTech #RiskManagement #ITSecurity

Does your organisation maintain a Vendor Security Incident Response Playbook? Let’s face it—no organisation is immune to third-party risks and incidents. With vendors playing such a critical role in business operations, having a plan in place to handle security incidents involving them is a must. Irrespective of whether you have one or not, here’s a simple, actionable approach to maintaining one: 1. Start with the Basics: - Identify your key vendors and the types of incidents you’re most concerned about (think data breaches, service outages, or compliance issues). - Set clear goals for your playbook—protecting data, minimizing downtime, and staying compliant should top the list. 2. Assign Roles and Responsibilities: - Get your key players involved: IT, cybersecurity, procurement, legal, and vendor management. - Make it crystal clear who’s doing what—whether it’s reporting, decision-making, or follow-ups. 3. Plan for Common Scenarios: Outline playbooks for situations like: - A vendor’s data breach: Who gets notified, and how do you respond? - Service outages: How do you escalate and recover? - Compliance violations: What’s the plan to address regulators or customers? 4. Set Communication Rules (Most important) - Make sure vendors know how to report incidents (a secure portal or email works great). - Agree on a timeline for notifications (24 hours is a good benchmark). 5. Test It Out - Run through “what if” scenarios with your vendors. - Use these exercises to iron out kinks and improve the plan. 6. Keep It Fresh - Review and update the playbook regularly. New risks pop up all the time, so stay ahead of them. Practical Tip: Don’t overcomplicate it. Your playbook doesn’t need to be perfect—it just needs to be actionable and evolve as you learn. So, how are you managing vendor security risks today? Do you already have a response plan, or is this on your to-do list?
