100 IBM Cloud Interview Questions and Answers for Freshers

  1. What is IBM Cloud?

    • Answer: IBM Cloud is a suite of cloud computing services offered by IBM, providing Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) offerings. It allows businesses to build, deploy, and manage applications and services on a scalable and secure platform.

  2. Explain IaaS, PaaS, and SaaS.

    • Answer: IaaS (Infrastructure as a Service) provides virtualized computing resources like servers, storage, and networking. PaaS (Platform as a Service) offers a platform for developing, running, and managing applications without managing the underlying infrastructure. SaaS (Software as a Service) delivers software applications over the internet, eliminating the need for local installation and maintenance.

  3. What are some key services offered by IBM Cloud?

    • Answer: Key services include compute (virtual servers), storage (object storage, block storage), databases (SQL, NoSQL), networking (VPC, load balancers), security (firewall, identity and access management), AI & Machine Learning services (Watson), and more.

  4. What is a virtual machine (VM) in IBM Cloud?

    • Answer: A virtual machine is a virtualized computer system running on IBM Cloud's infrastructure. It provides the same functionality as a physical server but is isolated and managed within the cloud environment.

  5. How is IBM Cloud different from other cloud providers like AWS or Azure?

    • Answer: IBM Cloud distinguishes itself through its strong focus on hybrid cloud solutions, enterprise-grade security, and its integration with IBM's other technologies like Watson AI and blockchain. Each provider has strengths in different areas; AWS is known for its breadth of services, Azure for its strong integration with Microsoft technologies.

  6. Explain the concept of a Virtual Private Cloud (VPC) in IBM Cloud.

    • Answer: A VPC is a logically isolated section of the IBM Cloud's infrastructure that provides a dedicated and secure environment for your resources. It allows you to create your own private network within the public cloud.

  7. What are IBM Cloud's security features?

    • Answer: IBM Cloud offers various security features, including data encryption at rest and in transit, access control via IAM, firewalls, intrusion detection systems, and compliance certifications (e.g., ISO 27001, SOC 2).

  8. What is IBM Watson? How does it integrate with IBM Cloud?

    • Answer: IBM Watson is a suite of AI and machine learning services. It integrates seamlessly with IBM Cloud, allowing developers to easily incorporate AI capabilities into their cloud-based applications using APIs and pre-built services.

  9. What is Kubernetes and how is it used in IBM Cloud?

    • Answer: Kubernetes is an open-source container orchestration platform. IBM Cloud offers managed Kubernetes services (like IBM Kubernetes Service) that simplify the deployment, scaling, and management of containerized applications.
