Slide 1: 1 Cloud Computing Computing Evolution : 2 Computing Evolution Now 40’s 70’s 80’s Mobility explosion Collaboration High level of interconexion between users Web platform growing Pressure over companies data centre. Why : 3 Why Contrary to last “big innovations”, cloud computing didn’t sprout from a young genius from Silicon valley. “is the logical result from the last 30 years in computation. In certain way, is a return to past, time sharing taken to the maximum”. Just 6% of currently installed servers capacity is used 30% aren’t used but weren’t unplugged from the network. Definition It combines a lot of concepts from latter years in computing: a huge number of multicore PCs and servers (both physical or virtual) running together trough broadband networks.. Why Amazon was pioneer: they have a critical mass in Christmas, but during the rest of the year, they have the infrastructure available and developed a lot of technology so support their business. How we see it : 4 How we see it The subject is still blur, and opinion of experts and executives from customers and suppliers are diverse: Definitive Will kill another ways of computing Will be the computing itself Another fade Just a name for “Network virtualization” Hot issue in crisis scenario: costs cuting new opportunities flexibility Off shoring: BRIC Develop this box. Will it remain? Costs Business opportunity Facilitator for new business What led to actual phase : 5 What led to actual phase Terms related to Cloud Computing Virtualization SOA REST Widget mash up Grid computing: Hw resources sharing Web 2.0 Internet service Bus Saas Iaas Paas Players : 6 Players Software on demand Grid computing: massive processing Elastic computer: By 2012, the global market for cloud computing will be $95 billion Merryll Linch You can take it with you : 7 You can take it with you Are gadgets important? As wireless technology gets better and cheaper, more and more different kinds of objects will connect directly to the cloud. Numbers : 8 Numbers 80% fortune companies 1000 will pay to use cloud computing services and 30% will pay for infrastructure. Gartner 33% of IT business will be in Cloud Computing Gartner Market : 42 billon IDC 95 billion Merryl Linch Numbers around CC are always impressive: 8 2011 2012 At this moment, the 5 major search engines together have 2.000.000 computers 2009 Microsoft data centre in Chicago: 610.000 servers They have already used cloud… : 9 They have already used cloud… Powerset: a start-up that is creating a natural language powerful search. When they need to catalogue the web, they buy cloud services. New York times: to create 11.000 pdfs, they needed to subcontract cloud services Schumacher Group (emergency rooms for hospitals): almost affected by Katrina hurricane, they was growing quickly but was having problems to create regional offices to support it. Running some systems remotely was the answer. Starbucks: using Salesforce CRM to create the new idea website as a online community. US Olympic Committee: using AT&T service to handle a busy traffic during the games SOGETI: The consultancy company owned by Cap Gemini contracted cloud services from IBM Blue Cloud to a whole-company brainstorming program. What is already available : 10 What is already available Email (Yahoo, Gmail, etc) Human resources CRM ( Office Applications Backup Storage Cloud PROs : 11 Cloud PROs Customer Supplier Flexibility: new needs can be solved quickly. Elasticity: temporary needs can be solved and you can “return” the infrastructure after the pick. New business: Smaller investment Time-to-market: Faster Implementation Synergies: Hardware investment can be spread Economy of scales: Hardware investment can be spread Alliance: Intel, HP e Yahoo Hardware consolidation: Best use of money invested in hardware Global Model: Data centres are distributed around the world, using better conditions: employees, nature, energy, etc… Costs: employees, nature, energy, etc… Smaller, TCO reduction. For big costumers, cloud is a long-term option. Not just a solution for the next 12 months. Geographical Distribution: Better services for disperse companies and easier mobility. Cloud CONTRAS : 12 Cloud CONTRAS Customer Supplier Lack of cost advantage: Not achieving ROI before turn people sceptical with CC . Strategy: Large databases; critical data; old systems; systems that require specific hardware Migration: Current enterprise apps can't be migrated conveniently. Management: Difficulty of managing cloud applications. Safety: To manage customer data, the identification management must be solved Liability: …… Latency: …… Lack of Service levels agreements: Cloud providers still are not taking accountability for the platforms Putative Risk: Legal, regulatory and business. Can our data be “elsewhere”? Pricing: How it is being charged. Migrate from boxes to services is a lesson to learn. Performance: Data bases can be less quick Challenge: management of resources, over many locations and with various tenants. Computing is not core business for many suppliers and CC solution can be discontinued. Slide 13: 13 Cloud architecture must supply a management infrastructure that includes functions as: Computational resources provisioning; Dynamic workload balancing; Performance monitoring. How would be an CC architecture? Slide 14: 14 Examples of CC Architecture Slide 15: 15 Examples of CC Architecture Slide 16: 16 Examples of CC Architecture Slide 17: 17 Slide 18: 18 Data.ti Nr 262 – February 2009 The Economist IT's global “cloud” The evolution of data centres Software as a service Connecting to the cloud The economics of the cloud The long nimbus Computers without borders Sources and acknowledgments Offer to readers CIO The case against cloud computing Bibliography Slide 19: 19 This presentation is a summary of many readings and some chats.
