  1. 1. Cloud Computing Ashish Kumar Mishra(103022) 1
  2. 2. Cloud Computing describes a network based computing that takes place over the Internet, basically a step on from Utility Computing a collection/group of integrated and networked hardware, software and Internet infrastructure (called a platform). Using the Internet for communication and transport provides hardware, software and networking services to clients simple graphical interface or API (Applications Programming Interface). 2

  5. 5. Cloud Architecture Multi-core architectures Virtualization: bare metal, hypervisor. … VM0 VM1 VMn Web-services, SOA, WS standards Services interface Cloud application : data intensive, compute intensive , Storage intensive Storage Models: S3, BigTable, BlobStore, ... Bandwidth WS 64-bit processor 5
  6. 6. Cloud Deployment Models Community Cloud Private Cloud Public Cloud Hybrid Clouds Deployment Models Service Models Essential Characteristics Common Characteristics Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS) Resource Pooling Broad Network Access Rapid Elasticity Measured Service On Demand Self-Service Low Cost Software Virtualization Service Orientation Advanced Security Homogeneity Massive Scale Resilient Computing Geographic Distribution 6
  7. 7. Different Types Of Cloud’s Characteristics Private Clouds • Cloud is controlled completely by the enterprise • All data in resource under control of legal and contractual umbrella of the organization • Require Capital Expenditure and Operational Expenditure and highly skilled labor Public clouds • External organizations provide the infrastructure and management of the cloud • Billed based on usage • Data in an offsite organization outside the legal and regulatory umbrella • Difficult to document the physical location of data at any particular moment 7 Hybrid Clouds •Combine public and private clouds •Coordination between the private and public service management system

  9. 9. Security and Challenge 9  Protecting datacenters must first secure cloud resources and uphold user privacy and data integrity.  Trust overlay networks could be applied to build reputation systems for establishing the trust among interactive datacenters.  A watermarking technique is suggested to protect shared data objects and massively distributed software modules.  These techniques safeguard user authentication and tighten the data access- control in public clouds.  The new approach could be more cost-effective than using the traditional encryption and firewalls to secure the clouds.
