The cloud at your service

The cloud at your service

1. 1. What is cloud computing?

   • 1.1. Five main principles that define cloud computing
     • Pooled computing resources
       • Availablerse to any subscriber us
     • Virtualization
       • High utilization of hardware assets
     • Elasticity
       • Dynamic scale without CAPEX
     • Automation
       • Build, deploy, configure, provision, and move, all without manual intervention
     • Metered billing
       • Per-usage business model; pay only for what you use
   • 1.2. Benefits that cred form moving to the cloudan be garne
     • Economic benefits of the change from capital to operational expenses
     • Agility benefits from not having to procure and provision servers
     • Efficiency benefits that may lead to competitve advanteg
     • Security stronger an better in the cloud
   • 1.3.Classifying cloud layers: different types for different uses
     • IaaS
     • PaaS
     • SaaS
     • Private clouds as precursors of public cloud

2. 2. Understanding cloud computing classifications

   • 2.1 The technological underpinnings of cloud cmputing
     • Achieving high economies of scale with cloud data centers
     • Ensuring high server utilization in the cloud with virtualization
     • Controlling remote servers with cloud API
     • Saving persistent data in cloud storage
     • storing your application´s structured data in a cloud database
     • Elasticity: scaling your application as demand rises and falls
   • Understanding the different classifications of clouds
     • Amazon EC2: Infraestructure as a service
     • Microsoft Azure: Infraestructure as a service
     • Google App Engine: Plataform as a Service
     • Ruby on rails in a cloud: Platafor as a Service
     • Salesforce.com: Platafor as a Service
     • Private clouds: Data Center as a Service
       • Concerns about private cloud
         • Private clouds are small scale
         • Legacy applications don't cloudify easily
         • On-premises doesn't mean more secure
         • Do what you do best
     • Amazon virtual private cloud

3. 3. The business case for cloud computing

   • 3.1. The economics of cloud computing
     • Traditional IT vs. colocation vs. managed services vs. cloud model
   • 3.2.Where does the cloud make sense?
     • Limited lifetime requirement / short-term need
     • Scale variability/ volatility
     • Non strategic applications / low organization value
   • 3.3 Where does the cloud not make sense?
     • Legacy systems
     • Applications involving real-time / mission-critical scenarios
     • Applications dealing with confidential data
   • 3.4. Zero capital Startups
   • 3.5. Small and medium businesses
     • Corporate website
     • Back-up and file storage systems
     • New product development
   • Cloud computing in the enterprise

4. 4. Security and the private cloud

   • 4.1. Information security in the public cloud
     • Security concerns slowing cloud adoption
     • Major cloud data center security
       • Physical security
       • SAS 70 certification
     • Public cloud access control measures
       • Billing validation - credit card
       • Identify verification via Phone (out of band)
       • Sign in credentials
       • Access keys
       • X.509 certificates
       • Key pairs
     • Major cloud network and data security
       • Operating system security
         • The OS of hsot system
         • Guest OS
         • Stateful firewall
         • Signed API calls
       • Network security
       • Co-mingling security
       • System control security
       • Data storage security
     • Application Owner´s role
   • 4.2 Rational for a private cloud
     • Defining a private cloud
       • Virtualization
       • Elasticity
       • Automation
       • Pooled resources
       • Metered billing
     • Private cloud
       • Security considerations
       • Certainty of resources availability
       • Large utility-computing demand
       • Economies of scale
       • Concerns abou deploying a private cloud
         • Private clouds are small scale
         • Legacy applications don't cloufify easily
         • On-premises doesn't necessarily mean more secure
         • Do what you do best
       • Private cloud deployment options
         • Open source
         • Propietary software
         • Hosted offering
