Cloud network engineering interviews at tech giants require specialized knowledge beyond traditional networking – particularly when it comes to cloud-native services. In this final installment of our interview preparation series with Kam Agahian, we explore the specialized networking services that frequently appear in technical assessments.

Security takes center stage as we discuss the critical boundary between networking and security responsibilities. Kam explains that while routing traffic to firewalls falls squarely on the network engineer, security policies and posture typically belong to dedicated security teams at larger organizations. We compare traditional VM-based third-party firewalls with cloud-native security services, highlighting the architectural considerations for each approach.

DNS architectures represent another technical area where candidates must demonstrate proficiency. Beyond understanding traditional name resolution, you'll need familiarity with the hybrid cloud architectures that enable communication between on-premises and cloud environments. Kam singles out DNSSEC as deserving special attention during your preparation.

The landscape of multi-cloud connectivity has evolved dramatically, moving beyond simple cross-cloud connections to sophisticated integration patterns. Candidates who demonstrate awareness of recent developments – like Oracle's strategy of placing databases directly in other providers' data centers – stand out in interviews by showing they stay current with industry trends.

Throughout our conversation, we emphasize research as a critical interview preparation strategy. Review all cloud-related job postings at your target company to understand their technology ecosystem and identify potential multi-cloud scenarios. This contextual knowledge allows you to tailor your responses to the specific environment you'll potentially be working in.

The landscape of cloud security is rapidly evolving as AWS flexes its muscles with a suite of new native security offerings unveiled at AWS re:Inforce. From enhanced threat correlation capabilities in AWS Security Hub to seamless Transit Gateway integration for Network Firewall, these announcements signal Amazon's strategic expansion into territory traditionally dominated by third-party security vendors.

We dive deep into the HPE-Juniper acquisition that finally received regulatory approval, but with interesting conditions – including the requirement to license parts of the coveted Mist AI technology. This could potentially open doors for competitors to leverage the same technology that made Juniper so attractive to HPE in the first place, creating a fascinating dynamic in the networking market.

The most compelling theme emerging from AWS re:Inforce centers around Amazon's continued investment in native security tooling. New offerings like AWS Shield Network Security Director and IAM Access Analyzer directly challenge third-party CSPM providers, while improvements to existing services reduce the friction and complexity of implementing robust security controls. For organizations already invested in the AWS ecosystem, these integrated solutions offer compelling advantages – but they also raise important questions about vendor lock-in and multi-cloud strategies.

Security vendors without a strong moat or differentiated value proposition should be concerned. As cloud service providers continue to enhance their native security capabilities, the pressure on third-party tools will only intensify. This trend follows closely on the heels of Google's acquisition of Wiz, suggesting that cloud security is becoming an increasingly strategic battleground for the major providers.

For security professionals navigating these waters, the proliferation of overlapping security services presents both opportunities and challenges. While AWS continues to simplify implementation, the growing catalog of similar-sounding services can create confusion about which tools to use in which scenarios. As we discuss on the podcast, this appears to reflect AWS's organizational structure as much as customer needs – shipping the org chart rather than truly differentiated services.

What's your security strategy in this evolving landscape? Are you embracing native cloud security tools or maintaining investments in third-party solutions? The answers may vary widely depending on your organization's cloud adoption strategy, but one thing is clear – the security vendor ecosystem is transforming before our eyes.

The invisible threads connecting Kubernetes and networking infrastructure form the backbone of today's cloud-native world. In this revealing conversation with Marino Wijay from Kong, we unravel the complex relationship between traditional networking concepts and modern container orchestration.

Marino brings a unique perspective as someone who entered the Kubernetes ecosystem through networking, explaining how fundamental networking principles directly translate to Kubernetes operations. "If you don't have a network, there is no Kubernetes," he emphasizes, highlighting how reachability between nodes forms the foundation of cluster communication.

The network evolution within Kubernetes proves fascinating – from the early "black box" approach where connectivity was implicit to the sophisticated Container Network Interfaces (CNIs) like Cilium that offer granular control. Network engineers approaching Kubernetes for the first time might feel overwhelmed, but as we discover, concepts like DHCP with DNS registration, NAT, and load balancing all have direct parallels within the Kubernetes networking model.

Our discussion ventures into the practical challenges organizations face when implementing service mesh technologies. While offering powerful capabilities for secure pod-to-pod communication through mutual TLS, service mesh introduces significant complexity. Marino shares insights on when this investment makes sense for enterprises versus smaller organizations with more controlled environments.

The conversation takes an especially interesting turn when exploring how AI workloads are transforming Kubernetes networking requirements. From GPU-enabled clusters to specialized traffic patterns and the concept of Dynamic Resource Allocation as "QoS for AI," we examine how these resource-intensive applications are pushing the boundaries of what's possible.

Whether you're a network engineer curious about containers or a Kubernetes administrator looking to deepen your networking knowledge, this episode bridges crucial gaps between these interconnected worlds.

When automation fails, it fails spectacularly—and at scale. The recent Google Cloud outage that took down over 54 global services for more than seven hours demonstrates this perfectly. A simple error—blank fields in automated policy updates—cascaded into widespread failures affecting millions of users worldwide. This episode dives deep into what went wrong, how it happened, and what it means for cloud resilience in the AI era.

We also explore Cisco's dramatic pivot at Cisco Live 2025, where they've committed to refreshing their entire hardware stack and integrating AI throughout their ecosystem. Their new LLM called Deep Network suggests a future where networking infrastructure makes intelligent decisions autonomously. We discuss whether Cisco can deliver on these promises and what the unification of their Meraki and Catalyst lines might mean for customers.

The Ultra Ethernet Consortium has finally released their 1.0 specification, establishing a comprehensive standard for high-performance computing environments. This 600+ page document marks a significant milestone in creating viable alternatives to InfiniBand for AI workloads. Meanwhile, Network-as-a-Service pioneer Meter secured $170 million in Series C funding, raising questions about the actual size and sustainability of the NaaS market.

On the cybersecurity front, we examine two concerning developments: the mass exodus of leadership from CISA during heightened threat conditions, and a novel zero-click vulnerability in Microsoft 365 Copilot that can expose sensitive data without any user interaction. This "Echo Leak" vulnerability demonstrates how AI systems that automatically scan content create entirely new attack vectors that organizations must defend against.

Join us for a fast-paced discussion about these pivotal developments in cloud computing, networking technology, and cybersecurity. What does all this mean for your infrastructure strategy? Listen and find out.

Entrepreneurship is often glorified as the ultimate career goal, but what happens when running your own business loses its luster? Jason Gintert takes us behind the scenes of his journey from corporate life to co-founding WAN Dynamics, and then back to the corporate world as CTO of Laketec.

The entrepreneurial path wasn't always smooth. "The first two years were kind of rough," Jason reveals, describing how his income dropped to half of his previous corporate salary and required significant belt-tightening at home. Even as the business grew, unexpected challenges emerged – from the stress of having employees depend on you for their livelihood to the constant cash flow battles when large clients took 60-90 days to pay invoices.

Perhaps most surprising was Jason's realization that business ownership didn't provide the freedom he expected. "It's a misconception that when you have a business, you're your own boss," he explains. "You report to your employees, your customers, your stakeholders – everybody who depends on you." Despite successfully growing the company and navigating the explosive demand for remote access solutions during COVID, Jason found himself increasingly forced into sales roles he didn't want.

After selling WAN Dynamics and briefly working for the acquiring company, Jason took four months to decompress before joining Laketec. His transition back to corporate life brought welcome relief – consistent schedules, healthcare benefits, and the ability to focus

What does it take to write the books that build the backbone of the networking industry? In this energetic conversation with Jason Gooley, Technical Evangelist at Cisco and author of numerous certification guides, we dive into the fascinating world of technical education and the art of making complex networking concepts accessible to learners.

Jason shares his remarkable journey from networking novice who once believed the myth that "CCIEs make more than the president" to becoming the author selected to take over the iconic CCNA certification guides from Wendell Odom after his 23-year, 10-edition legacy. The responsibility is enormous—with Cisco's Network Academy having certified 17 million professionals and aiming for another 25 million in the next decade, Jason's words will shape countless careers.

We explore the delicate balance required when creating technical content: providing enough depth for certification success without overwhelming readers, adding engaging storytelling without sacrificing accuracy, and addressing varied audience backgrounds without assuming too much or too little prior knowledge. As Jason beautifully puts it, "When I write, it feels like I'm talking... like I'm explaining it to a specific person." This approach transforms what could be dry technical manuals—"paper cuts to the eyes"—into relatable learning experiences.

For anyone working in technology, the episode offers valuable insights on continuous learning in a rapidly evolving field. Jason describes technology as "a train... the second you step on, you're moving with it." The key is simply starting somewhere: "Don't be afraid to get on the train. Just do 'hello world.' Get a Raspberry Pi. Use Alexa to turn off your lights."

Whether you're pursuing certifications, teaching others, or creating educational content, this episode provides practical wisdom on making technical knowledge accessible, relevant, and engaging.
