Cloud computing is the delivery of computing resources (like servers, databases, networking, storage) over the internet on-demand and on a pay-as-you-go basis. Scalability (resources scale with demand)<\/p>\n<\/li>\n Cost-efficiency (no upfront infrastructure)<\/p>\n<\/li>\n Flexibility (deploy solutions globally in minutes)<\/p>\n<\/li>\n<\/ul>\n Example:<\/strong> A startup can scale during a viral campaign without buying physical servers\u2014just pay for what you use.<\/p>\n There are four major models:<\/p>\n Public Cloud:<\/strong> Managed by providers (e.g., AWS, Azure); cost-effective and scalable.<\/p>\n<\/li>\n Private Cloud:<\/strong> Dedicated to a single organization; better control and security.<\/p>\n<\/li>\n Hybrid Cloud:<\/strong> Combines both; balance of security and cost.<\/p>\n<\/li>\n Multi-cloud:<\/strong> Uses services from multiple providers; avoids vendor lock-in.<\/p>\n<\/li>\n<\/ul>\n IaaS (Infrastructure as a Service):<\/strong> Like AWS EC2; full control over virtual machines.<\/p>\n<\/li>\n PaaS (Platform as a Service):<\/strong> Like Google App Engine; focus on app development without managing infrastructure.<\/p>\n<\/li>\n SaaS (Software as a Service):<\/strong> Like Gmail or Salesforce; fully managed software.<\/p>\n<\/li>\n<\/ul>\n Each has a different level of control and responsibility.<\/p>\n This model defines what the cloud provider secures (e.g., infrastructure) vs. what the user secures (e.g., data, configurations).<\/p>\n In IaaS<\/strong>, more responsibility lies with the user.<\/p>\n<\/li>\n In SaaS<\/strong>, most of the security is the provider\u2019s job.<\/p>\n<\/li>\n<\/ul>\n Example:<\/strong> You must secure your AWS S3 buckets, even though AWS manages the server they\u2019re stored on.<\/p>\n High availability comes from:<\/p>\n Redundancy across regions<\/p>\n<\/li>\n Load balancing to handle traffic<\/p>\n<\/li>\n Automatic failovers<\/p>\n<\/li>\n<\/ul>\n Example:<\/strong> An e-commerce site on AWS might use Elastic Load Balancer and multi-AZ deployment to prevent downtime.<\/p>\n Encrypt data at rest and in transit (TLS, AES-256)<\/p>\n<\/li>\n Use IAM roles and policies<\/p>\n<\/li>\n Enable Multi-Factor Authentication<\/p>\n<\/li>\n Perform regular audits (AWS CloudTrail, Azure Monitor)<\/p>\n<\/li>\n<\/ul>\n Tip:<\/strong> Never leave storage buckets publicly accessible unless required.<\/p>\n It allows developers to run code without provisioning or managing servers. You\u2019re charged per execution, and the provider handles scaling and availability.<\/p>\n Steps:<\/strong><\/p>\n Assess app dependencies<\/p>\n<\/li>\n Choose a migration strategy:<\/p>\n Rehost<\/strong> (lift-and-shift)<\/p>\n<\/li>\n Refactor<\/strong> (modify for cloud)<\/p>\n<\/li>\n Rebuild<\/strong> (cloud-native)<\/p>\n<\/li>\n<\/ul>\n<\/li>\n Use tools like AWS Migration Hub<\/p>\n<\/li>\n<\/ul>\n Test in a staging environment before going live.<\/p>\n Containers (e.g., Docker, Kubernetes) package apps and dependencies together for consistent performance across environments. Improve scalability<\/p>\n<\/li>\n Work well with microservices<\/p>\n<\/li>\n Run efficiently in cloud-native systems<\/p>\n<\/li>\n<\/ul>\n Right-size your instances<\/p>\n<\/li>\n Use auto-scaling and spot\/reserved instances<\/p>\n<\/li>\n Monitor usage with cost tools (e.g., AWS Cost Explorer)<\/p>\n<\/li>\n Shut down idle resources<\/p>\n<\/li>\n<\/ul>\n Pro Tip:<\/strong> Consider serverless for irregular workloads.<\/p>\n Security concerns<\/strong><\/p>\n<\/li>\n Compliance (e.g., GDPR, HIPAA)<\/strong><\/p>\n<\/li>\n Vendor lock-in<\/strong><\/p>\n<\/li>\n Legacy system integration<\/strong><\/p>\n<\/li>\n Upskilling your team<\/strong><\/p>\n<\/li>\n<\/ul>\n It\u2019s not always smooth sailing\u2014but proper planning helps.<\/p>\n Check logs (CloudWatch, Azure Monitor)<\/p>\n<\/li>\n Review deployment or config changes<\/p>\n<\/li>\n Inspect network settings<\/p>\n<\/li>\n Test individual components<\/p>\n<\/li>\n<\/ol>\n Example:<\/strong> If a GCP app goes down, start by checking Compute Engine logs and roll back any recent updates.<\/p>\n Q: Do these questions apply to all cloud providers?<\/strong> Q: Should I memorize these answers?<\/strong> Q: Are container and serverless technologies important for interviews?<\/strong> These cloud computing interview questions aren\u2019t just for landing a job\u2014they\u2019re for building the mindset of a cloud-native professional.
