    • Amazon Cloud Services Kalpak Shah Clogeny Technologies Pvt. Ltd. [email_address] The forecast is ..... cloudy Clogeny Technologies Pvt. Ltd.
    • What is cloud computing?
      • Next generation of computing after Mainframe, Personal computers, Client-Server and the Web
      • New platform and delivery model providing dynamically scalable and often virtualized resources
      • 1000 servers for 1 hour = 1 server for 1000 hours!
      • Accessibility – Connectivity – Viability
      • Beware of cloud imposters!
        • Online != Cloud
      Clogeny Technologies Pvt. Ltd.
    • Cloud Stack
      • Infrastructure as a Service (IaaS)
        • Amazon EC2, Rackspace CloudServers
      • Platform as a Service (PaaS)
        • Google AppEngine, Heroku
      • Software as a Service (SaaS)
        • SalesForce.com, ZOHO
      Clogeny Technologies Pvt. Ltd.
    • Cloud Economics
      • Economies of scale
        • 5-7 times decrease in cost as compared to data centers
      • Pay as you go
        • 1 hour of Amazon EC2 can cost as less as 8.5 cents or 4 rupees!
      • No CAPEX, only OPEX
      • Practically infinite scalability – go from 1 machine to 1000 in an hour!
        • That is fast provisioning!
      • Start-ups can focus on core proposition than infrastructure.
      • Departments in enterprises need not wait for budget approvals
      Clogeny Technologies Pvt. Ltd.
    • AWS Services Clogeny Technologies Pvt. Ltd.
    • About all services - 1
      • Amazon’s web services scale as and when needed
      • Completely pay as you go
      • SOAP and REST interfaces will be available
        • All features have a comprehensive web services API
      • Libraries for popular languages like Java, .Net, Perl, RoR are available
      • Pricing is complicated & the pricing calculator more so!
        • For example, $0.10 per 1 million IO requests
      • Amazon cloud is available at 3 different regions
        • 2 in US and 1 in Europe
        • Regions are priced differently depending on scale, local taxes and other factors
      Clogeny Technologies Pvt. Ltd.
    • About all services - 2
      • Backed by a decently good SLA(Service Level Agreement) of around 99.9% uptime.
      • And most importantly:
        • All data transfer in and out of Amazon cloud is charged
        • Around $0.15/GB, though in-coming data is free until June
        • As volume increases price decreases starting from about 50TB
        • Data transfer across availability zones is charged
      Clogeny Technologies Pvt. Ltd.
    • Elastic Compute Cloud
      • Resizable compute capacity – boot servers in minutes for scaling your applications/portals
        • You can choose compute units(cores) and memory as per your needs
      • Pricing starts from $0.085 per hour
      • Variety of OS’s are available – Linux, Windows, OpenSolaris
      • OEMs provide bundled Amazon Machine Instances (AMI)
        • Pre-packaged applications like Oracle, SQL, media servers available to choose from
        • Licensing becomes pay as you go as well!
      • Attached storage is not persistent!
        • A running server can be “bundled” and converted into an AMI for later use.

      • BitTorrent protocol interface available for high-scale distribution
      • Transfer between regions is also charged
      • AWS Import/Export can be used for large datasets

      • EBS volume can be “attached” to any running instance in same region
        • Move disks between instances as needed
      • Snapshots of EBS volumes can be taken for incremental backups
        • New volumes can be created from snapshots
        • Snapshots can be shared with other users!
      • Volumes can fail!
        • Annual failure rate of 0.1%-0.5% (still lesser than drives we use)
