Study Notes
Module 1
- Computing is being transformed into a utility-based model
- Users access services based on their needs, regardless of location
- Cloud computing is the latest paradigm
- Cloud computing focuses on how systems are designed, applications developed, and existing services used
- Cloud computing offers dynamic provisioning of services: computing, storage, network and IT infrastructure
- Resources are made available on a pay-per-use basis through the internet from cloud vendors
- Cloud usage allows scaling infrastructure up or down, in hours, and users only pay for the used resources
- Cloud computing offers dynamic scaling of resources and infrastructure, fitting different business needs
- Users do not need to deeply understand the infrastructure needed by their applications
- Utility computing concepts are similar to water, electricity, and telephony
Cloud computing significantly transforms organizational management of technological resources by enabling internet access to computing power, storage, and applications without heavy hardware investments.
- Leonard Kleinrock, an internet pioneer, envisioned "computer utilities" in 1969
- This vision anticipated the massive transformation of the computing industry in the 21st century
- Cloud services are now readily accessible on demand
- Users pay providers for the services they use
Vision of Cloud Computing
- Cloud computing allows anyone with a credit card to provision virtual hardware, runtime environments, and services
- This is used for as needed without upfront costs
- Cloud computing removes IT maintenance burden from the user
- Cloud computing delivers IT services as utilities
- Cloud computing is a way of trading IT services as utilities in an open market
Defining a Cloud
- Cloud computing is a popular term, encompassing various concepts
- These concepts include virtualized infrastructure, hardware on demand, utility computing, IT outsourcing and other related areas
- Cloud computing systems are now widely used in numerous contexts
- Cloud computing is a model that allows easily accessing computing resources from anywhere through the internet-based network
- Users can provision these resources and pay as they need
A Closer Look
- Cloud computing helps various organizations create more effective computing systems
- Examples are large enterprises like the New York Times, or smaller companies, and research organizations
- Cloud computing facilitates the ability to access and edit data from anywhere and any device
Cloud Deployment Models
- Public, private, and hybrid clouds are major deployment methods
- Public clouds provide infrastructure (eg., virtualized datacenters) to anyone on a subscription basis
- Private clouds mirror public clouds, but on a company's own infrastructure
- Hybrid clouds utilize both public and private cloud resources
Cloud Computing Reference Model
- The Cloud Computing Reference Model depicts various cloud services in a layered structure
- The basic structure is Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS)
Historical Developments
-
Computing grids, mainframe computing, cluster computing, and grid computing have influenced cloud computing
-
Mainframes: Large, powerful, highly reliable computers used for large data processing tasks
-
Clusters: Commodity computers, connected together forming a single system, cheaper than mainframes. used for parallel and high-performance computing
-
Grids: A further evolution of clusters, able to distribute resources to multiple locations
-
Web 2.0 and service-oriented computing have contributed and shaped the cloud environment
Virtualization
- Virtualization enables different computing environments simulation of hardware interface expected by an operating system
- Virtualization makes it possible to co-habit different software stacks on top of the same computer hardware
- Creating isolated virtual machin instances, running separately and providing high-performance servers with multiple instances
Web 2.0
- Web 2.0 is the primary interface of cloud computing services
- Web 2.0 applications are extremely dynamic with new updates constantly
- Web 2.0 applications are able to use multiple devices such as phones, dashboards, and TVs
- Web 2.0 applications emphasize interaction and are lightweight
- Web 2.0 leverages user feedback to continuously improve and add features.
Service-Oriented Computing
- Services are the core reference model
- The main structure and building blocks are services composed of distributed tasks
- Service-oriented computing allows ease of access to services from various devices and in different locations
- The key concept is that services are independent of platforms
