Unit 2 -Cloud Computing Architecture

The document discusses the architecture and lifecycle of cloud computing, detailing key concepts such as cloud technology, deployment models (private, public, hybrid), and various service models (SaaS, PaaS, IaaS). It also covers virtualization methodologies and types, emphasizing their roles in cloud systems, and highlights the complexities and interdependent components of cloud ecosystems. Additionally, it addresses concerns related to cloud computing, such as availability, security, and data integrity.

UNIT-II CLOUD COMPUTING ARCHITECTURE
CONTENT Cloud Computing Technology Cloud Architecture Cloud Modeling and Design Foundation Grid Cloud and Virtualization Virtualization and Cloud Computing.
Cloud Lifecycle Model The Cloud Life Cycle (CDLC) is the repeated life cycle model for growth deployment and delivery of cloud.  Requirement and Analysis  Architect  Implementation and Integration  Quality Assurance and Verification  Deploy, Testing and Improvement  Monitor, Migrate and Audit
Role of Cloud Modeling and Architecture Service Models  Cloud Software as a Services  Cloud Platform as a services  Cloud Infrastructure as a Services Deployment Model  Private Cloud  Community Cloud  Public Cloud  Hybrid Cloud
Cloud Computing Architecture • Cloud Computing is an Internet-based technique using shared resources available remotely. • Eg. Gmail and Yahoo Cloud Computing Type  Public Cloud  Private Cloud  Hybrid Cloud
Cloud Computing Reference Model • Cloud Enablement Model • Cloud Deployment Model • Cloud Governance and Operations Model • Cloud Ecosystem Model Cloud System Architecture • Single Cloud Site Architecture • Redundant 3-tier Architecture • Multi-datacentre Architecture
Cloud Deployment Model • Private Cloud • Public Cloud • Hybrid Cloud • Community Cloud • Combined Cloud • Inter Cloud (Cloud of Clouds)
Cloud Ecosystem Model • Cloud ecosystem is a term, which defines the complexity of the system in terms of its interdependent components that work together to enable cloud services.

REASON FOR THE USAGE OF LOW CLOUD COMPUTING Cloud Availability Cloud security Erosion of data integrity Data replication and consistency issues Potential loss of privacy Lack of auditing and logging visibility Potential for regulatory violations.
Definition of Virtualization • ‘Virtualization’ is a methodology for dividing the computer resources to more one execution environment by applying more concepts like partitioning, time- sharing, machine simulation and emulation.
Types of Virtualization
Server Virtualization: It is a kind of virtualization , used for masking of server resources , which includes number of physical servers , processors and operating Systems. Network Virtualization: It is a method where network resources are combine based on available bandwidth. Storage Virtualization: In this Virtualization , where a pool of physical storage from different network of storage devices appear as single storage device
Desktop Virtualization: It supports various computing such as utility and dynamic , testing development and security. Hardware Virtualization: It is the abstraction of computing resources from the software that uses cloud resources. It involves embedding virtual software into server hardware components
CLOUD VS VIRTUALIZATION
Virtualization In Grid • The main focal point in grid computing lies in secure resource sharing in accessing computers, software and data in a dynamic atmosphere, sharing of those resources has to be fine-tuned and handled in a highly controlled manner.
Virtualization In Cloud • Virtualization is a tool for system administrators, which has many technical uses than a cloud. Virtualization allows IT organization to perform multiple operations using a single physical hardware.
Virtual infrastructures • The internet provides services such as research, mining, e-mail and maps. • Provides an environment where non- trusted application can be run. • Adopts isolation techniques. • Allows dynamics deployment of application. • Applied optimization in os. • Manages as a single services.
