Which Cloud computing concepts to prepare for interviews?

Let’s break down the essential cloud computing concepts you need to master.

Key Cloud Computing Concepts for Interviews

Understanding cloud computing is crucial for modern tech roles. Here are the main concepts you should focus on:

Cloud Service Models

Infrastructure as a Service (IaaS)

IaaS provides virtualized computing resources over the internet. Think of it as renting servers and storage instead of buying physical hardware.

Platform as a Service (PaaS)

PaaS offers a platform allowing developers to build, deploy, and manage applications without worrying about the underlying infrastructure.

Software as a Service (SaaS)

SaaS delivers software applications over the internet on a subscription basis. Examples include Gmail and Salesforce.

Cloud Deployment Models

Public Cloud

Public clouds are operated by third-party providers and offer services over the internet to multiple organizations.

Private Cloud

Private clouds are dedicated to a single organization, providing greater control over data and security.

Hybrid Cloud

Hybrid clouds combine public and private clouds, allowing data and applications to be shared between them.

Multi-Cloud

Multi-cloud involves using services from multiple cloud providers to avoid dependency on a single vendor.

Core Cloud Services

Compute Services

These include virtual machines, containers, and serverless computing, enabling scalable and flexible application deployment.

Storage Services

Understand different storage types like object storage (e.g., Amazon S3), block storage, and file storage, each suited for various use cases.

Networking Services

Learn about Virtual Private Clouds (VPCs), subnets, load balancers, and content delivery networks (CDNs) that ensure efficient data flow and accessibility.

Scalability and Elasticity

Scalability

Scalability refers to the ability to handle increased workloads by adding resources.

Elasticity

Elasticity is the capability to automatically adjust resources based on demand, ensuring optimal performance and cost-efficiency.

Virtualization

Virtualization allows multiple virtual machines to run on a single physical server, maximizing resource utilization and flexibility.

Load Balancing

Load balancing distributes incoming network traffic across multiple servers to ensure no single server becomes overwhelmed, enhancing reliability and performance.

Security in the Cloud

Identity and Access Management (IAM)

IAM manages user identities and their access to resources, ensuring secure and appropriate access controls.

Data Encryption

Encrypting data both at rest and in transit protects sensitive information from unauthorized access.

Containers and Orchestration

Docker

Docker containers package applications with their dependencies, ensuring consistency across different environments.

Kubernetes

Kubernetes automates the deployment, scaling, and management of containerized applications, making it easier to handle complex applications.

Serverless Computing

Serverless computing allows developers to build and run applications without managing server infrastructure, focusing solely on code.

Monitoring and Logging

Effective monitoring and logging are essential for maintaining system health, diagnosing issues, and ensuring optimal performance.

Cost Management

Understanding how to manage and optimize cloud costs is vital to ensure that cloud resources are used efficiently without overspending.
