cloud computing delivery models,provider perspective.pptx

Cloud delivery models are frameworks that specify how cloud services are offered to customers, outlining the division of responsibilities between the service provider and the customer. The three main models are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). A cloud provider's perspective on these models involves building, managing, and securing the underlying infrastructure to support each service layer.

2. Cloud Delivery Models & Provider Perspective Exploring the fundamentals of cloud services and the intricate world of cloud providers.

3. Understanding Cloud Delivery Models: An Introduction Cloud computing has revolutionized how businesses operate, offering unprecedented flexibility, scalability, and efficiency. At its core, cloud computing delivers on-demand computing services—from applications to storage and processing power—over the internet with a pay-as-you-go pricing model. This presentation will demystify the key cloud delivery models and delve into the strategic perspective of cloud service providers.

4. Why Cloud? The Foundation of Modern IT The shift to cloud is driven by critical business needs: Cost Efficiency: Reduce capital expenditure on hardware and maintenance. Scalability: Instantly adjust resources up or down based on demand. Agility: Rapidly deploy new services and innovations. Reliability: High availability and disaster recovery capabilities. Global Reach: Access services from anywhere, anytime.

5. The Cloud Spectrum: From On-Prem to Fully Managed On-Premise Full control, high capital cost, all management internal. Hybrid Cloud Mix of on-prem and cloud, balancing control and flexibility. Private Cloud Dedicated cloud infrastructure for single organization. Public Cloud Shared infrastructure, pay-as-you-go, high scalability. Each model offers different levels of control, cost, and complexity, catering to diverse business requirements.

6. Infrastructure as a Service (IaaS): Building Blocks of the Cloud IaaS provides fundamental computing resources over the internet, including virtual machines, storage, networks, and operating systems. Users manage their applications, data, runtime, and OS, while the provider handles the underlying infrastructure. It's like renting virtual hardware. Key Features: Virtualization, scalable compute and storage, networking. Use Cases: Hosting websites, data analysis, big data processing, development and testing environments. Provider Role: Manages servers, virtualization, storage, and networking hardware.

7. Platform as a Service (PaaS): Developers' Workbench PaaS offers a complete development and deployment environment in the cloud, allowing developers to build, run, and manage applications without the complexity of building and maintaining the infrastructure. It abstracts away the OS, servers, and middleware. Key Features: Application deployment, database management, web server support, development tools. Use Cases: Rapid application development, analytics, business intelligence. Provider Role: Manages the operating system, server software, and development tools.

8. Software as a Service (SaaS): Ready-to-Use Solutions SaaS delivers fully functional software applications over the internet, typically on a subscription basis. Users simply access the application through a web browser or mobile app, with no need for installation, maintenance, or infrastructure management. It's the most common form of cloud service for end-users. Key Features: Web access, multi-tenancy, automatic updates, centralized management. Use Cases: CRM (e.g., Salesforce), email (e.g., Gmail), collaboration tools (e.g., Slack), office suites (e.g., Microsoft 365). Provider Role: Manages all aspects of the application and its underlying infrastructure.

9. The Cloud Provider's View: Business Drivers & Value Proposition Cloud providers are not just technology companies; they are strategic partners enabling digital transformation. Their success hinges on delivering massive value to customers while maintaining profitable operations. Revenue Growth Subscription models, usage-based billing, and diversified service offerings drive income. Customer Acquisition Building trust through security, compliance, and reliable service is paramount. Innovation Leadership Constant development of new services (AI/ML, IoT, serverless) keeps them competitive.

10. Cloud Provider Operations: Infrastructure, Security & Scalability Behind the scenes, cloud providers manage a monumental undertaking to deliver seamless service: Global Data Centers Vast networks of facilities housing millions of servers, ensuring low latency and data redundancy worldwide. Robust Security Multi-layered defenses: physical security, network firewalls, encryption, identity management, and compliance adherence. Elastic Scalability Automated systems for provisioning and de-provisioning resources on demand, handling fluctuating workloads. Operational Excellence 24/7 monitoring, automated maintenance, and expert teams to ensure high availability and performance.

11. Monetization & Competition: A Provider's Landscape Monetization Strategies Pay-as-you-go: Billing based on actual resource consumption. Reserved Instances: Discounts for committing to longer terms. Tiered Pricing: Different rates for varying service levels or features. Value-added Services: Offering managed databases, analytics, AI services at a premium. Competitive Landscape The cloud market is dominated by a few hyperscalers (AWS, Azure, Google Cloud) but also includes niche players and regional providers. Competition revolves around: Pricing and cost efficiency Breadth and depth of services Developer experience and ecosystem Global footprint and compliance Customer support and partnership programs
