1.What is cloud computing?

•  Cloud computing delivers computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet.

 

2.What are the different service models in cloud computing?

• IaaS (Infrastructure as a Service)

• PaaS (Platform as a Service)

• SaaS (Software as a Service)

 

3.How does virtualization play a role in cloud computing?

• Virtualization allows multiple operating systems to run simultaneously on a single physical server, enabling efficient resource utilization and scalability.

• ​

What are the benefits and challenges of cloud adoption?

● Benefits: Scalability, cost-efficiency, flexibility, and reduced IT overhead.

● Challenges: Security concerns, vendor lock-in, network latency, and potential downtime. What are the components of a cloud infrastructure?

● Servers, storage, networking, databases, and other underlying resources. How does load balancing work in cloud environments?

● Load balancing distributes incoming traffic across multiple servers to prevent overload and improve performance. What is a virtual network?

● A virtual network is a logical network created within a physical data center, providing isolation and security for cloud resources.

 

What are the security considerations in cloud environments?

● Data encryption, access controls, vulnerability scanning, and regular security audits.

 

What are the key features of popular cloud platforms like AWS, Azure, and GCP?

● AWS: Comprehensive suite of services, including EC2, S3, Lambda, and RDS.

● Azure: Strong integration with Microsoft products, including Azure Active Directory and Azure SQL Database.

● GCP: Focus on scalability and performance, with services like Compute Engine, Cloud Storage, and BigQuery.

 

How do you choose the right cloud platform for your organization's needs?

● Consider factors like cost, scalability, security, compliance requirements, and integration with existing systems.

 

What are the advantages of using serverless computing?

● Pay-per-use pricing, automatic scaling, and reduced management overhead.

 

How does containerization (e.g., Docker) relate to cloud computing?

● Containers provide a portable and consistent environment for applications, making them easier to deploy and manage in the cloud.

 

What is cloud migration?

● The process of moving applications, data, and infrastructure to a cloud environment.

 

How do you assess the suitability of an application for cloud migration?

● Consider factors like complexity, dependencies, regulatory requirements, and potential benefits.

 

What are the challenges associated with cloud migration?

● Data migration, application compatibility, security concerns, and potential downtime.

 

What is cloud governance?

● A set of policies, processes, and controls to ensure that cloud resources are used efficiently and effectively while meeting security and compliance requirements.

 

What is cloud architecture?

● The blueprint for designing and building cloud-based applications and systems.

 

How do you design a scalable cloud application?

● Consider factors like horizontal and vertical scaling, microservices architecture, and distributed systems.

 

What is microservices architecture?

● A design approach that breaks down applications into small, independent services that can be developed, deployed, and scaled independently.

 How do you ensure high availability and fault tolerance in cloud environments?

● Use redundancy, load balancing, and automatic failover mechanisms.

 

What is cloud DevOps? ●

A collaborative approach that combines software development and IT operations to deliver applications and services faster.

 

What are the benefits of using automation tools in cloud environments?

● Increased efficiency, reduced errors, and faster deployment times.

 

How do you implement continuous integration and continuous delivery (CI/CD) in the cloud?

● Use tools like Jenkins, GitLab CI/CD, or AWS CodePipeline to automate the build, test, and deployment process.

 

What is infrastructure as code (IaC)?

● Managing infrastructure using code, allowing for version control, automation, and reproducibility.

 

What is serverless computing, and how does it differ from traditional cloud computing?

● Serverless computing allows developers to build and run applications without managing servers. It's ideal for event-driven workloads and microservices.

 

What are the security implications of using public cloud services?

● Public cloud environments share resources with other tenants, increasing the risk of data breaches.Organizations must implement strong security measures like encryption, access controls, and regular vulnerability assessments.

 

How do you optimize cloud costs?

● Use reserved instances, spot instances, and auto-scaling to optimize costs. Regularly review usage patterns and identify opportunities for cost reduction.

 

What is cloud bursting?

● Cloud bursting involves scaling resources up or down dynamically to meet demand. It's useful for handling temporary spikes in workload.
