4. Auto Scaling: Auto-scaling dynamically adjusts computing resources like virtual machines or instances based on workload demands. It optimizes performance and cost efficiency by scaling up resources during high-demand periods and reducing them during times of lower usage.

5. Backend as a Service (BaaS): BaaS is a cloud-based service model that provides developers with ready-to-use backend infrastructure and tools, such as databases, authentication, cloud storage, and APIs, allowing them to focus on front-end development.

6. Big Data: Big data refers to massive datasets that traditional data processing tools can’t handle efficiently. Cloud platforms often provide big data analytics tools like AWS EMR or Google BigQuery to process and analyze such data at scale.

7. Cloud Backup: Cloud backup is a service that securely stores data in the cloud, ensuring data recovery in case of hardware failure, ransomware attacks, or natural disasters.

8. Cloud Computing: Cloud computing delivers computing services (servers, storage, databases, networking, etc.) over the internet, allowing users to access resources on demand and pay only for what they use.

9. Cloud Provider: A cloud provider is a company offering cloud computing services, including infrastructure, platforms, and software, over the internet. These services allow organizations to access scalable services (storage, servers, applications, etc.) without needing to directly manage hardware. Examples include AWS, Microsoft Azure, Google Cloud Platform, and IBM Cloud.

10. Content Delivery Network (CND): A CDN is a distributed network server used to deliver web content (i.e., web pages, images, videos, and scripts) to users based on their geographic location to the nearest server in the network. It improves website performance, reduces latency, and enhances user experience.

11. Data Migration: Data migration is the process of transferring data from one system, format, or storage location to another, such as from on-premises data centers to a cloud environment. It ensures seamless transitions during upgrades, consolidations, or system changes, ensuring minimal downtime and data integrity.

12. Elasticity: In computing, elasticity refers to the ability of a system to dynamically scale computing resources up or down based on workload demands. It ensures optimal resource utilization, cost efficiency, and consistent performance by automatically adapting to changing needs in real-time.

13. Edge Computing: Edge computing is a distributed data processing approach that places computation and storage near the source of data generation. It reduces latency, improves efficiency, and supports real-time applications like IoT and autonomous systems.

14. Google Cloud Platform (GCP): GCP is a collection of cloud computing services that offer infrastructure, platforms, and software solutions. It provides scalable infrastructure, storage, machine learning, and development tools, enabling businesses to build, deploy, and manage applications efficiently across a global network.

15. Hybrid cloud: A hybrid cloud combines on-premises infrastructure, private cloud services, and public cloud resources. It enables seamless data and application integration, allowing businesses to leverage the benefits of both, such as flexibility, security, and scalability.

16. Infrastructure as a Service (IaaS): IaaS is a cloud computing model offering virtualized resources over the internet, such as servers, storage, and networking. It allows businesses to scale infrastructure on demand while reducing the need for physical hardware management.

17. Kubernetes: Kubernetes is a free, open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It boosts the features of scalability, resource efficiency, and availability in diverse environments that include cloud, on-premise, and hybrid systems.

18. Load Balancer: Load balancer distributes the incoming network traffic across multiple servers to ensure no single server is overwhelmed. It enhances the performance, reliability, and availability of the application by optimizing resource utilization and preventing server overloads.

19. Middleware: Middleware is a software layer that enables seamless communication and interaction between various applications, systems, or components. It provides services like messaging, authentication, and data management, simplifying integration and enhancing functionality.

20. Multi-cloud: Multi-cloud refers to using services from multiple cloud providers simultaneously to avoid vendor lock-in, optimize costs, or meet specific business requirements.

21. On-Premise: On-premise refers to IT infrastructure that is physically located within a company’s premises, as opposed to being hosted in the cloud.

22. Pay-As-You-Go: Pay-as-you-go is a billing model in cloud computing where users are charged based on actual resource usage, ensuring cost efficiency.

23. Public Cloud: A public cloud is a computing environment where a third-party provider delivers services like storage, computing power, and applications. These resources are shared among multiple users, offering high scalability and cost efficiency.

24. Private Cloud: A private cloud is a computing environment designed exclusively for a single organization. It provides the same scalability, flexibility, and on-demand access to resources as public cloud services but with greater control over data, security, and customization.

25. Platform as a Service (PaaS): PaaS delivers a fully configured platform with resources and tools that help developers create, deploy, and manage applications, removing the need to handle the underlying infrastructure.
