Study Notes

  • Cloud Computing involves different cloud computing models

Cloud Deployment Models

  • Public Cloud: Computing resources are shared among multiple users or organizations and are accessible over the Internet through a third-party provider
  • Private Cloud: Computing resources are dedicated to a single organization, offering enhanced security and tight control over data and infrastructure
  • Community Cloud: Infrastructure is shared by a specific community or group of organizations with shared concerns such as government agencies or entities with similar missions and security needs
  • Hybrid Cloud: Organizations use a mix of on-premises, private, and public cloud to keep some servers on premises while extending capabilities to the cloud for flexibility and cost-effectiveness

Cloud Deployment Models Summary

  • Private: Used when a single organization requires complete control and security for sensitive applications, not exposed to the public
  • Public: Cloud resources are owned and delivered by a third-party provider, offering full cloud computing advantages with options like Amazon AWS, Microsoft Azure, Google GCP, and IBM Cloud
  • Hybrid: A mixture of private and public clouds allows organizations to keep servers on-premises and extend some capabilities to the cloud
  • Community: Infrastructure used exclusively by a specific community, such as government entities, to meet security, policy, and compliance considerations

Cloud Service Models

  • IaaS (Infrastructure as a Service): Provides basic computing components where users have control over the operating system, applications, and data
  • PaaS (Platform as a Service): Streamlines application development with a platform offering development tools and services
  • SaaS (Software as a Service): Delivers fully functional software applications over the internet, removing the need for users to manage the underlying infrastructure

Infrastructure as a Service (IaaS)

  • IaaS provides virtualized infrastructure components like servers, storage, and networking
  • Users have control over the operating system, applications, and data

Platform as a Service (PaaS)

  • PaaS provides developers with a platform offering development tools and services
  • Developers can focus on coding and deploying applications without managing the underlying infrastructure

Software as a Service (SaaS)

  • SaaS delivers fully functional software applications over the internet
  • Users access and use the software without managing the underlying infrastructure

Challenges for Cloud Computing

  • Availability of service: Addresses what happens when the service provider cannot deliver
  • Data confidentiality and audit-ability: A serious problem
  • Diversity of services: Data organization and user interfaces at different service providers limit user mobility
  • Data transfer bottleneck: Many applications are data-intensive

Data Transfer Challenge

  • Migration to the cloud and data transfer from on-premises servers can be challenging with Peta-scale to Exa-scale Data
  • 1 TB equals 1024 GB, 1PB equals 1024 TB, and 1EB equals 1024 PB
  • AWS Snowball: A petabyte-scale data transport solution that uses secure appliances to transfer large amounts of data into and out of the AWS cloud
  • AWS Snowmobile: An Exabyte-scale data transfer service used to move extremely large amounts of data to AWS, allowing transfers up to 100PB per Snowmobile

More Challenges

  • Performance unpredictability occurs because of resource sharing
  • Resource virtualization and performance isolation used for QoS guarantees
  • Elasticity is needed to support scaling up and down quickly
  • Resource management: Managing different workloads on large data centers poses a challenge
  • Security and confidentiality are major concerns for sensitive applications like healthcare

Summary of Cloud Computing

  • Main driver is economics
  • Service Models include SaaS, PaaS, and IaaS
  • Deployment Models include Private, Community, Public, and Hybrid
  • Key characteristics: On-Demand, Multi-tenancy, Elasticity, Scalability, Cost-Efficiency, High Availability, Resiliency, and Pay as you go
  • Cloud computing faces challenges: Security, Privacy, Availability, and Data Transfer.
