Unit I - Visualisation in Cloud Computing

Overview

This unit covers the foundational aspects of cloud computing, explaining its significance, characteristics, and the various models and architectures associated with it. It introduces key concepts such as cloud service models (SaaS, PaaS, JaaS, and Storage), cloud deployment models, and the process of migrating to the cloud.

Topics

  1. Importance of Cloud ComputingImportance of Cloud ComputingImportance of Cloud Computing Definition Cloud Computing is the delivery of various services over the internet, including data storage, servers, databases, networking, and software. Rather than owning their computing infrastructure or data centers, companies can rent access to anything from applications to storage from a cloud service provider. Key Concepts Scalability:* Ability to increase or decrease IT resources as needed. Cost Efficiency:* Pay-as-you-go pricing model, reducing capital ex
  2. Characteristics of Cloud ComputingCharacteristics of Cloud ComputingCharacteristics of Cloud Computing Definition Cloud Computing is a model that enables convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Key Concepts On-Demand Self-Service* Broad Network Access* Resource Pooling* Rapid Elasticity* Measured Service* Detailed Explanation Cloud comput
  3. Pros and Cons of Cloud ComputingPros and Cons of Cloud Computingw## Pros and Cons of Cloud Computing Definition Cloud Computing refers to the delivery of computing services, including storage, processing, networking, and software, over the internet (the cloud). It allows users to access and use these resources on a pay-as-you-go basis, rather than owning and maintaining physical infrastructure. Key Concepts Advantages (Pros)** * Cost Efficiency * Scalability * Accessibility * Disaster Recovery * Security * Collaboration * Innovation Disadv
  4. Migrating into the CloudMigrating into the CloudMigrating into the Cloud Definition Cloud migration is the process of moving data, applications, and other business elements from on-premises infrastructure to a cloud computing environment. This can involve moving to a public cloud, private cloud, or hybrid cloud solution, depending on the organization's requirements. Key Concepts Assessment and Planning* Choosing the Right Cloud Model* Data Migration* Application Migration* Security* and Compliance** Testing* and Validation** Optimization*

  7. Cloud Service Models - SaaS, PaaS, JaaS, StorageCloud Service Models - SaaS, PaaS, JaaS, StorageCloud Service Models: SaaS, PaaS, IaaS, and Storage Definition Cloud service models define how cloud services are delivered and consumed. These models include Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Storage as a Service (STaaS). Each model provides different levels of control, flexibility, and management for users. Key Concepts Software as a Service (SaaS)** Platform as a Service (PaaS)** Infrastructure as a Service (IaaS)** Storage
  8. Cloud Architecture - Logical Architecture, Holistic Reference Model, System ArchitectureCloud Architecture - Logical Architecture, Holistic Reference Model, System ArchitectureCloud Architecture: Logical Architecture, Holistic Reference Model, and System Architecture Definition Cloud Architecture refers to the components and subcomponents required for cloud computing, including a front-end platform, back-end platforms, cloud-based delivery, and a network. This architecture ensures the efficient and secure deployment, operation, and scaling of cloud services. Key Concepts Logical Architecture** Holistic Reference Model** System Architecture** Detailed Explanation
  9. Cloud Deployment ModelsCloud Deployment ModelsCloud Deployment Models Definition Cloud Deployment Models define the type of cloud environment based on ownership, size, and access. These models determine how resources are managed, who can access them, and how they are distributed. The main deployment models include Public Cloud, Private Cloud, Hybrid Cloud, and Community Cloud. Key Concepts Public Cloud** Private Cloud** Hybrid Cloud** Community Cloud** Detailed Explanation Each cloud deployment model offers different levels of control
