Cloud-native applications are built on cloud-provided services from their conception. Unlike traditional applications that are often retrofitted for the cloud, cloud-native applications use cloud-developed paradigms such as microservices architecture, containerization, and orchestration from the outset. A typical cloud-native architecture divides an application into independent, loosely coupled services. These services communicate through APIs and can be developed, deployed, and scaled individually. This architecture ensures resilience and flexibility, as issues in one service do not bring down the entire application.

I've used Docker extensively for packaging applications consistently across environments. I build images with specific base operating systems and dependencies, which eliminates the ‘it works on my machine' problem. For orchestration, I've managed small Kubernetes clusters—maybe 5-10 nodes for internal services and side projects. I can write YAML manifests for deployments, services, and persistent volumes, and I understand concepts like namespaces, labels, and selectors. That said, Kubernetes is deep, and I'd say I'm competent for small to medium clusters but not yet at the level where I'm designing multi-region Kubernetes infrastructure. I'm actively learning more through personal projects and online courses. Docker I feel very solid with—I've built many production images and optimized them for size and security.

I had to explain to our CFO why we needed to spend $200K on a disaster recovery setup that we hopefully would never use. I could have talked about RTO and RPO, but instead I framed it as insurance. I showed data on how much an hour of downtime would cost us in lost revenue and customer impact, then explained that for $200K upfront and ongoing, we could recover from a regional outage in minutes instead of hours. I walked her through a scenario: if our primary data center in one region went offline, here's what customers would experience with our current setup, and here's what they'd experience with DR in place. I also explained that this wasn't theoretical—it happened to a competitor last year. She approved the budget.

High availability and disaster recovery are different problems, so I tackle them separately. For HA, I use redundancy at every layer—multiple instances behind a load balancer, replicated databases, auto-scaling groups that spin up replacements if instances fail. I've deployed across multiple availability zones so a single zone's failure doesn't take us down. For disaster recovery, I establish RTO and RPO targets first—how quickly do we need to recover, and how much data can we afford to lose? Then I design backward from there. We run automated daily backups of databases and critical file systems, store them in geographically separate regions, and document the recovery procedures. The critical part: I actually test these recovery plans quarterly by doing disaster recovery drills. It's revealed gaps every time, and it's better to find them in a drill than during an actual outage.

Set a clear plan of what to do in the case of a disaster, ensure all team members are aware of the plan and know how to implement it. - Data replication: Use replication services such as AWS S3 Cross-Region Replication to keep real-time copies of critical data. - Failover mechanisms: Configure failover systems using load balancers and DNS routing services such as AWS Route 53. - Testing, simulation, and training: Regularly simulate disaster scenarios to validate recovery plans. Train team members on how to execute the plan.

This question explores the challenges you perceive in the role. Here's a sample answer: “My least favourite aspect of desktop support is dealing with the repetitive nature of some issues. Often, the same problems recur due to systemic or unresolved underlying issues, which can be frustrating when solutions are not implemented across the board. Additionally, managing user expectations and explaining technical limitations in layman's terms can be challenging, especially when users are distressed or under pressure. However, these challenges also provide opportunities for improving communication skills and system management. Ultimately, this enhances the support experience for both the user and the support team.”

I see infrastructure as a support function for what developers are building. When a developer asks for a new database or wants to add a service, I don't just say ‘no' or hand them a form. I try to understand what they're trying to achieve, suggest options based on our infrastructure and constraints, and help them implement it. I've also built strong relationships with security—they tell me what compliance or security requirements matter for our industry, and I make sure those are baked into infrastructure from the start rather than bolted on later. With ops and other infrastructure engineers, I believe in documentation and knowledge sharing. When I implement something new, I document it so others can maintain it. I also make time to help junior engineers debug issues.

First, I'd gather context. Is this new, or has it always been this way? Is it causing customer impact—slow response times or errors? If it's not causing problems, maybe 85% is acceptable and we just need to make sure it doesn't spike higher. Assuming it's new and causing slowdowns, I'd drill down. I'd look at application metrics—has request volume increased, or is each request using more CPU? I'd check for runaway processes using top or ps to see which process is consuming CPU. I'd also check system metrics like context switches and I/O wait. If I/O wait is high, it might not actually be the application—the server might be waiting on disk or network. Let's say I discover a recent code change caused an inefficient database query. I'd work with the developer to optimize that query or add caching. If it's sustained traffic growth, I might scale horizontally—add more servers behind the load balancer to distribute load. I'd also set auto-scaling policies so if CPU stays above 75% for five minutes, new servers automatically spin up. This prevents us from firefighting every spike.

Identify and terminate idle or cost-inefficient resources. - Implement resource tagging: Assign tags to track cost attribution across projects or teams. - Leverage spot instances: Use surplus compute capacity at discounted rates for non-critical tasks. - Adopt cloud-native services: Use managed services instead of provisioning the entire infrastructure. For example, you could use AWS RDS instead of running a self-managed database. - Use appropriate pricing models: Commit to long-term use, such as a 3 year period for predictable workloads to get discounts compared to on-demand pricing. Use flexible plans like AWS Savings Plans to save on compute usage across different instance types. - Regularly review and refactor product architecture. Conduct periodic cost reviews to identify inefficiencies in your architecture which are inducing cost or latency.
