1 Some additional words about cloud computing
Lionel Brunie National Institute of Applied Science (INSA) LIRIS Laboratory/DRIM Team – UMR CNRS 5205 Lyon, France Master course /03/2017

2 What’s a Cloud ? "A Cloud is a type of parallel and distributed system consisting of a collection of interconnected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resources based on service-level agreements established through negotiation between the service provider and consumers” (Buyya et al.) “A large-scale distributed computing paradigm that is driven by economies of scale, in which a pool of abstracted, virtualized, dynamically-scalable, managed computing power, storage, platforms, and services are delivered on demand to external customers over the Internet” (Foster et al.) Start point: October/November IBM Blue Cloud Master course /03/2017

3 Types of clouds Public clouds (or external clouds)
resources are dynamically provisioned on a fine-grained, self-service basis over the Internet, via Web applications or Web services. the cloud is hosted, operated, and managed by a third-party vendor from one or more data/computing centers organizations/customers lease shared resources from public clouds, effectively becoming infrastructure tenants rather than owners computing becomes a public utility Private clouds (or internal clouds) emulate cloud computing on private networks Hybrid clouds merge multiple internal and/or external clouds Master course /03/2017

4 IaaS, PaaS, SaaS Infrastructure as a Service (IaaS)
provides computing environments/infrastructure i.e., hardware, software the provisioned infrastructure can dynamically scale up and down depending on the actual needs Amazon EC2 and S3 Platform as a Service (PaaS) high-level integrated environment to build and deploy applications restrictions on the type of applications but scalable platform Google’s App Engine for deploying Web applications Software as a Service (SaaS) delivers software to consumers through the Internet Salesforce: online CRM (Customer Relationship Management) Services ; Live Mesh from Microsoft: files and folders synchronization Master course /03/2017

5 Other XaaS offerings Storage as a Service
Data(base) as a Service (DaaS) Process as a Service - Business Process as a Service Network as a Service (NaaS) Integration as a Service  Security as a Service - Identity as a Service Testing as a Service Master course /03/2017

6 Visit of a Cloud vendor web site
« Values to customers include: Reducing IT management complexity and skill requirements Sharing resources among multiple applications Accelerating application launches Supporting both existing and emerging, data-intensive workloads Master course /03/2017

7 Characteristics From the customer point of view:
Scalability Reliability Flexibility Cost Security and Privacy Performance Ubiquitous and fast access Quality of Service Service Level Agreement Pricing system Simple to use From the internal point of view Virtualization « Grid » management Master course /03/2017

8 Comparison of some cloud platforms
From Foster et al. Master course /03/2017

9 Example: Amazon EC2/S3 Compute Cloud EC2 (Elastic Cloud Computing)
pricing: « private » virtualized servers (« instances ») of different types example: High-CPU Extra Large Instance 7 GB of memory 20 EC2 Compute Units 1690 GB Storage Pricing on a per hour basis for each instance type: from $0.085/hour for the small standard "On-Demand" virtual machine running Linux to 29x more for the largest one running Windows (Jan. 2011). The data transfer charge ranges from $0.08 to $0.15 per gigabyte, depending on the volume Data Cloud S3 (Simple Storage Service) pricing: from $0.055 to $0.14 per GB-month (standard storage), + bandwidth usage (from $0.05 to 0.12 per GB – EU price) + requests (from $0.001 to $0.01 per 1000 requests) 556 stored billion objects (Oct. 2011) (Marc 2010: 102 billion objects) data transfer is charged by TB / month data transfer, depending on the source and target of such transfer.
