Cloud computing provides on-demand access to shared computing resources like networks, servers, storage, applications and services that can be rapidly provisioned with minimal management effort. It evolved from technologies like client/server, web services, grid computing and utility computing. Cloud computing offers advantages like reduced costs, flexibility, scalability and mobility compared to traditional server models. It is classified into public, private and hybrid cloud models based on their accessibility and three main service models of IaaS, PaaS and SaaS based on the level of control and customization they provide.
Cloud computing seminar
- 1. 1 CLOUD COMPUTING Common, Location-Independent, Online Utility On-Demand A. Aravindan Arun, Sr. System Admin Date: 11/01/2013
- 2. 2 Agenda Introduction Evolution of Computing Compare with Traditional Server Compare with Virtualization Server Cloud Computing Advantages / Benefits Cloud Computing Types Service Models Summary
- 3. 3 Evolution of Computing Client / Server - Distributed Web Services – Internet Technology Grid Computing – HPC Utility Computing – Metered Service Cloud Computing Next Generation Mainframe – Centralized
- 4. 4 Introduction Cloud is Internet-based computing, whereby shared computing resources (e.g., networks, servers, storage, application and other services) that can be rapidly provisioned and released with minimal management effect.
- 5. 5 The Traditional Server Concept Pros Easy to conceptualize Fairly easy to deploy Easy to backup Virtually any application/service can be run from this type of setup Cons Expensive to acquire and maintain hardware Not very scalable Difficult to replicate Redundancy is difficult to implement Vulnerable to hardware outages In many cases, processor is under-utilized
- 6. 6 The Traditional Virtualization Concept Pros Resource pooling Highly redundant Highly available Rapidly deploy new servers Easy to deploy Reconfigurable while services are running Optimizes physical resources by doing more with less Cons Slightly harder to conceptualize Slightly more costly (must buy hardware, OS, Apps, and so on...) Difficult auto scaling
- 7. 7 Technologies for Agility Virtualization The ability to run multiple Operating System on single physical system and share the underlying hardware resources. Utility Computing Offering computing resources as a metered service
- 9. 9 Cloud Computing Advantages On Demand Services Speed of Delivery Cost / Benefit ratio Software as a Subscription Reduced Software Maintenance Increased Scalability Elastic Nature User have full control over their instance
- 10. 10 Benefits Lower total cost operations (Pay-As-You-Go) Save Infrastructure setup & Maintenance Rapid, Request-driven provisioning Easy monitoring, managing & reports Storage and Retrieval of data Uninterrupted and Persistent Data Storage High Availability Automated and even distribution of traffic Flexible scaling of Resources
- 11. 11 Cloud Computing Characterized Consumer Perspective Single point of access - Self services with rich user experienced Virtualization - Increased system utilizations Automation - Automated service request and fulfillment Agility - Rapid Services provisioning Flexibility - Massive scaling of IT services as needed Usage Account - Utility based usage metrics Service Management - Modular services managed access Infra/Platforms/application/business stacks Security - Shared services delivered across trusted domains Cost Efficiency - Reduced CapEx with minimal to no asset ownership
- 12. 12 Cloud Computing Types Public Cloud Private Cloud Hybrid Cloud
- 13. 13 Public Cloud Infrastructure provisioned on-demand using publicly available resources. Computing resources are provided to customers through self-serve interface. Scalable computing resource on a temporary or periodic basis. Ability to acquire access to highly-quality pools of resources immediately and with minimal capital investment.
- 14. 14 Public Cloud Benefits Reduce Infrastructre cost and maintain cost Rapidly increase on-demand services, storage capacity and other need Public cloud available anywhere, anytime Scalable to meet individal or company needs High redundancy and available
- 15. 15 Private Cloud Private cloud avail within the corporate firewall using their own hardware. Flexible to organization needs. The Cloud architecture is dedicated to the organization and is not shared with other organization.
- 16. 16 Private Cloud Benefits Data will be safe and secure Scalable Bandwidth Access Suitable and highly support SLA Reliability
- 17. 17 Hybrid Cloud Hybrid Cloud = Private Cloud + Public Cloud Private cloud can extends their boundaries to access additional computing resources in the public cloud using secure communication (VPN).
- 18. 18 Hybrid Cloud Benefits Flexible computing resources Continued reduction of cost expenses Improved resource utilization and more efficient system
- 19. 19 Community Cloud A Cloud infrastructure that is shared by several organizations Often delivered securely via private network. Ability to bill the organization separately. Shared SLA's
- 20. 20 Service Delivery Models Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (Iaas)
- 21. 21 Service Delivery Models Source: Cloud Computing Use Cases, a white paper produced by the Cloud Computing Use Case Discussion Group, Version 2.0, 30 October 2009
- 22. 22 Services Delivery Models Infrastructure as a Service (IaaS) Consumer can utilize “Fundamental Computing Resources” such as Processing Unit, Storage, Networking and Operating System. Consumer can control the operating system, Storage, Application.
- 23. 23 IaaS Benefits Low IT Capital Investment and on-going operation Cost Shorter delivery time and Fully scalable Higher Level of Value-added services Reduces Maintenance, Monitoring and Management cost Easy to Manage
- 24. 24 Services Categories Platform as a Service (PaaS) – Allows users to create their own cloud based application using provider specific API's and/or libraries.
- 25. 25 PaaS Benefits Low Infrastructure & Lower Risk Lightweight development IDE Easy and quick deployment Reusable code and business logic Integration with other web services Centralized information management Secured and customized access Easy Collaboration
- 26. 26 Services Categories Software as a Service (SaaS) – Consumers purchase the ability to access and use an application or service that is hosted in the cloud.
- 27. 27 SaaS Benefits Shorter deployment time Global Availability Easier upgrades Lower Initial costs High Adoption
- 28. 28 Cloud Security Claims Based Authentication A trusted authority (Issuer) issues a signed security Token containing a set of claims (credentials) which is given to the application for validation. The application will authenticate the user if the security token is valid and signed by a trusted issuer
- 29. 29 Cloud of the future is an ecosystem Source: Cloud Computing Use Cases, a white paper produced by the Cloud Computing Use Case Discussion Group, Version 2.0, 30 October 2009
- 30. 30 Benefits & Summary Reduced Costs Easy to take snapshot – Storage, Instance Highly Automation Flexibility More Mobility Management Automation Lower Maintenance Cost Deploy Project Faster Scale as needed Location independent
