Grab, Southeast Asia's leading super-app for ridesharing and food delivery, recently completed a transformative overhaul of its app-building infrastructure by moving more than 200 Mac Minis from the cloud into a self-managed datacenter. Previously relying on a US cloud provider for its macOS Continuous Integration/Continuous Delivery (CI/CD) needs, Grab faced major cost pressures—macOS build minutes on cloud platforms were ten times pricier than Linux, and Apple's requirements meant paying for 24-hour blocks even during off-peak periods. Attempts to boost efficiency with macOS virtualization were hampered by performance and stability trade-offs. By shifting to on-premises infrastructure, with four racks housing over 200 Mac Minis in Malaysia, Grab gained 20-40% faster CI/CD performance and slashed costs by an estimated $2.4 million over three years. Automated provisioning with Jamf management tools minimizes maintenance overhead, giving Grab tighter control and a competitive edge in mobile app development. This bold move aligns with a broader trend in tech—cloud repatriation—where companies reclaim cost and performance benefits for critical workloads by moving off public cloud platforms. Grab's experience is a key case study for businesses wrestling with cloud expenses versus operational agility.

David Linthicum returns with a follow-up to his RSA predictions video—this time to see what actually happened at last week's RSA Conference and which calls held up under real-world scrutiny. Before the event, David laid out his expectations for the biggest cybersecurity themes, vendor narratives, and industry shifts likely to dominate the conversation. Now that RSA is over, it's time to review the results, separate hype from substance, and look at where those predictions were right on target.
In this video, David breaks down the major trends that emerged, compares them against his original forecast, and explains why certain themes gained traction while others fell flat. From AI security messaging to platform consolidation, cloud security strategy, and the ever-growing noise around cyber innovation, this is a candid scorecard on what RSA actually revealed.
This is not a victory lap for the sake of it. It's a practical look at how to read industry events more clearly, spot patterns before they become obvious, and understand what really matters beyond flashy announcements and packed expo floors. If you want sharp analysis, honest reflection, and a no-nonsense take on RSA's biggest storylines, this follow-up delivers the receipts.

In this video, I explain how I built a successful YouTube channel by combining thought leadership, audience trust, and a focused content strategy. My growth did not start on YouTube alone. It was built on my existing followers and more than 20 years of podcasting, which gave me a strong foundation in technology media, IT analysis, and digital audience building. I also share why understanding audience demand, viewer engagement, and content performance metrics is essential for long-term growth.
 
I discuss how cloud computing, artificial intelligence, enterprise technology, and IT strategy are high-value topics, but still serve a niche audience inside the broader technology industry. That means creators in these spaces need a smarter approach to YouTube marketing, social media promotion, audience targeting, and brand growth. I also cover the importance of choosing sponsors and brand partnerships that align with the mission of the channel and provide value to the audience. If you are interested in YouTube growth, tech influencer strategy, B2B content marketing, AI content strategy, or building authority in the cloud computing and enterprise IT space, this video offers practical insights you can apply right away.

We're on the edge of a real shift: the "cloud" may stop being purely a terrestrial phenomenon and become a layered network that includes orbit. The strongest case isn't that your favorite web app moves to space, but that space systems start acting like their own cloud region—compute, storage, and networking placed near satellites that generate massive amounts of data. If that happens, the first "clouds in space" won't look like hyperscale campuses; they'll look like compact, rugged orbital nodes that do AI inference, preprocessing, and caching, then beam results to Earth through high-throughput links. The big question is pace: in the near term, expect experiments and niche deployments for Earth observation, communications, and national security; mainstream adoption will require lower-cost launches, improved power and thermal designs, reliable optical crosslinks, and a clear cost advantage for specific workloads. Regulation and risk will shape it too—who owns the infrastructure, where the data "resides," and how you secure something you can't physically touch. So yes, we're likely to see "clouds in space," but as an extension of cloud architecture (edge + backbone), not a replacement for Earth regions—at least for a long while.

David Linthicum challenges the feel-good narratives that dominate cloud conversations and lays out five opinions that many teams avoid saying out loud. He argues that cloud repatriation is not a failure but a rational response to economics and performance, and that some workloads belong back on dedicated or private infrastructure. He warns that vendor lock-in isn't an edge case—it's the default outcome unless you design deliberately for portability. 
Linthicum also focuses on "cloud fragility": the hidden chain of dependencies that can turn a regional incident into broad service disruption, and why resilience must be engineered, not assumed. On costs, he pushes back on the idea that cloud is automatically cheaper, emphasizing that it can be a great bargain only when architectures, usage, and governance are disciplined. Finally, he questions whether hyperscalers pass efficiency gains to customers, urging viewers to measure unit costs and demand accountability. 
The video is a blunt, practical reset for leaders planning migrations, optimizing spend, or rethinking multicloud and hybrid strategy. Expect examples, migration mistakes and a reminder that cloud is a tool, not a religion. If you're struggling with surprise bills, outages, or strategy whiplash, his checklist helps you decide what to keep, move, or unwind.
