Study Notes
Cloud Computing Fundamentals
- Cloud computing provides on-demand access to shared computing resources like servers, storage, databases, networking, and applications over the internet.
- Cloud computing uses a virtualized platform with elastic resources available on demand through dynamic provisioning of hardware, software, and data sets.
- The concept of "everything but the kitchen sink" is commonly used to illustrate the wide range of services and features that cloud computing encompasses.
Agenda
- Covers what cloud computing is.
- Includes essential characteristics of cloud computing
- Explores service models (laaS, PaaS, SaaS, CaaS)
- Examines deployment models
- Discusses cost management strategies.
- Investigates key differences in cloud adoption strategies.
- Explains "Green Cloud in Action".
What is Cloud Computing?
- Cloud computing delivers resources on demand, using the internet.
- Shared resources minimize individual infrastructure investment.
Cloud Computing in Daily Life
- Streaming services (Netflix, Spotify, YouTube) use cloud computing to stream content without downloads.
- File storage and sharing services (Google Drive, Dropbox) provide online access and eliminate the need for physical storage.
- Cloud-based communication and collaboration tools (Microsoft Teams, Slack, Zoom) facilitate real-time communication and collaboration.
- Cloud-based social media platforms (Facebook, Instagram, Twitter, Tiktok) rely heavily on cloud computing, storing substantial user data.
- Online shopping (Amazon, eBay) utilizes cloud computing to support websites, processing transactions, and inventory management.
- Financial services (Paypal) use cloud computing to manage payments, transactions, and balances.
- Cloud computing is integrated and used in diverse applications, including virtual assistants, online learning, cloud gaming, and smart home systems.
Cloud Computing Characteristics Diagram
- Essential characteristics include broad network access, rapid elasticity, measured service, and on-demand self-service.
- Resource pooling is used to optimize resource utilization and cost-efficiency.
- Service models include SaaS (Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service).
- Deployment models include public, community, private, and hybrid.
Essential Characteristics of Cloud Computing
- On-demand self-service: Customers can provision computing capabilities on their own.
- Broad network access: Cloud services are accessible over the network and available from various devices.
- Resource pooling: Resources are pooled to serve multiple customers and dynamically allocated based on demand.
- Rapid elasticity: Resources can be elastically scaled up or down to accommodate fluctuations in demand.
- Measured service: Cloud systems automatically monitor and manage resource use, and usage is measured for billing purposes.
Service Models Overview
- laaS (Infrastructure as a Service): Provides virtualized computing resources over the internet, and users manage the operating system, libraries, and applications. Examples include Amazon Web Services (AWS) and Microsoft Azure.
- PaaS (Platform as a Service): Delivers pre-configured platforms, development tools, and middleware for application development. Examples include Google Cloud Platform (GCP) and Microsoft Azure.
- SaaS (Software as a Service): Delivers fully functional software applications over the internet. Users manage only applications and data, not the underlying infrastructure. Examples include Google Workspace and Salesforce.
- CaaS (Container as a Service): Provides a platform for managing and deploying containerized applications. Examples include Kubernetes and Docker Swarm.
Pizza as a Service
- Presented as an analogy for different cloud service models, outlining the responsibilities of the user and the service provider for each.
Infrastructure as a Service (IaaS)
- IaaS provides virtualized computing resources, and users manage operating systems, libraries, and applications.
- Key characteristics include scalability, pay-as-you-go pricing, on-demand availability, and automation.
- Benefits of IaaS include cost savings, flexibility, and global reach.
Platform as a Service (PaaS)
- PaaS delivers a fully managed environment for application development, running, and management.
- Key characteristics include development frameworks, managed infrastructure, and integration services.
- Benefits include accelerated development, reduced complexity, cost-efficiency, and collaboration.
Software as a Service (SaaS)
- SaaS delivers fully functional software applications over the internet.
- Key characteristics include accessibility, subscription-based model, automatic updates, and multi-tenancy.
- Benefits include ease of use, cost-efficiency, scalability, and device independence.
Container as a Service (CaaS)
- CaaS provides a platform for managing, deploying, and scaling containerized applications.
- Key characteristics include container management, orchestration, flexibility, and API-driven automation.
- Benefits include developer efficiency, portability, pay-as-you-go pricing, and rapid deployment.
Deployment Models of Cloud Computing
- Public Cloud: Cloud infrastructure is owned and managed by a third-party provider and made available to the general public. Examples include AWS and Azure.
- Private Cloud: Cloud infrastructure is used by a single organization and can be managed either internally or by a third-party but is dedicated to that sole organization.
- Hybrid Cloud: Combines elements of private and public clouds, allowing data and applications to be shared between them.
- Community Cloud: Cloud infrastructure is shared by several organizations with common concerns, such as industry regulations. Suitable for specific security, compliance, or operational standards.
- Multi-Cloud: Leveraging multiple cloud service providers to optimize services within or across the different models.
Cost Management Strategies
- Optimizing Resource Allocation (Autoscaling): Dynamically adjusts computing resources based on demand.
- Cost-Effective Resource Reservations: Pre-paying for compute capacity to get discounts.
- Monitoring and Budget Alerts: Tools to monitor cloud spending and set alerts for overages.
- Serverless and Event-Driven Architectures: Pay only for actual execution time rather than always-on servers.
- Storage Optimization: Selecting the right storage types and managing data lifecycle for cost reduction.
Key differences in cloud adoption strategy
- Buying (Owning) a Cloud: High upfront costs, long-term ROI, potential hardware depreciation.
- Renting a Cloud: Moderate initial investment, fixed costs.
- Pay-as-You-Go (PAYG): Lower initial investment, flexible, good for scaling.
Green Cloud in Action
- Focuses on minimizing cloud services' environmental impact.
- Key principles include energy efficiency, renewable energy, resource utilization, and sustainable practices.
- Case studies of companies adopting green cloud practices are highlighted, such as Microsoft Azure and Google Cloud.
