Building in the cloud is only half the job — running it reliably and affordably is the other half.

Monitoring & logging

You can't manage what you can't see. Metrics, logs and alerts (Azure Monitor, AWS CloudWatch) tell you what's happening and warn you before users notice. Centralised logging is also essential for security investigations.

Disaster recovery

Interactive explainer

High Availability & Redundancy

Keeping services running through failure: load balancing and failover.

Tap or hover a part to learn more.

Redundancy

No single point of failure.

High availability starts by removing single points of failure — duplicate servers, links, power and paths so no one component can take the whole service down.

Check your understanding

1. What does a load balancer do?

2. Roughly how much downtime does 99.9% allow per year?

Plan for failure with backups and recovery targets: RTO (how quickly you must recover) and RPO (how much data loss is acceptable). High availability handles component failure; DR handles bigger disasters like a region outage.

Cost optimisation

Cloud bills grow silently. Right-size resources, shut down idle ones, use auto-scaling, and tag resources so costs are visible and owned. This connects to resilience.

Interview Intelligence

How this topic actually shows up in interviews — and how to demonstrate you understand it.

Why employers ask about this

Employers value engineers who keep services reliable AND cost-efficient — cloud waste is a real business problem.

Technical questions

How would you approach cloud cost optimisation?+

Right-size, remove idle resources, auto-scale, use commitments/reservations, and tag for visibility.

Behavioural questions

Tell me about reducing cost or improving reliability.+

STAR: the waste/outage, the change you made (right-sizing, HA, monitoring), and the saving/uptime gained.

Real-world scenarios

“The monthly cloud bill has doubled with no clear reason.”+

Expected answer: Use cost tools + tags to find waste, right-size and remove idle resources, and set budgets/alerts.

What employers expect

That you understand cloud concepts well enough to be productive and safe on Azure or AWS from day one.

Frequently asked questions

What are RTO and RPO?

RTO is how quickly you must recover a service; RPO is how much data loss (time) is acceptable.

How do you control cloud costs?

Right-size resources, remove idle ones, use auto-scaling and tag resources so spend is visible and owned.

Why is logging important in the cloud?

For troubleshooting, alerting before outages, and as essential evidence for security investigations.
