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.
