Cloud Computing: AWS for Lean Startups
This document discusses cloud computing and Amazon Web Services (AWS). It defines cloud computing and outlines its history and types including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It describes the characteristics of public and private clouds. It provides examples of popular IaaS and PaaS vendors including AWS and describes key AWS services like EC2, S3, RDS, and more. It also outlines AWS pricing models including on-demand, reserved, and spot instances as well as the AWS free tier for new customers.

- 4. What is aCloud?
- 5. Cloud Computing defined •“… a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet” – Wikipedia
- 6. Cloud Computing defined •“Clouds are hardware-based services offering compute, network and storage capacity where: Hardware management is highly abstracted from the buyer, Buyers incur infrastructure costs as variable OPEX, and Infrastructure capacity is highly elastic” – McKinsey & Co. Report: “Clearing the Air on Cloud Computing”
- 7. Cloud Computing defined •“Cloud computing has the following characteristics: 1. The illusion of infinite computing resources… 2. The elimination of an up-front commitment by Cloud users… 3. The ability to pay for use…as needed…” – UCBerkeley RADLabs
- 8. Cloud Computing defined •“... a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” – National Institute of Standards and Technology (NIST)
- 9. Cloud Computing defined •“Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically re- configured to adjust to a variable load (scale), allow-ing also for an optimum resource utilization. This pool of resources is typically exploited by a pay-per-use model in which guarantees are offered by the Infrastructure Provider by means of customized SLAs.” – Paper by Vaquero et. al.: “A break in the clouds: towards a cloud definition”
- 10. What is aCloud? • Datacenter with an API
- 11. What is aCloud? • Timesharing 2.0
- 12. Common Ground? • Pay-per-use (no commitment, utility prices) • Elastic capacity - scale up/down on demand • Self-service interface • Resources are abstracted / virtualized
- 13. Types of Cloud • Public Cloud • Private Cloud • Hybrid Cloud
- 14. Public vs. PrivateCloud Public Cloud Private Cloud Variable expenses (OPEX) Capital expenses (CAPEX) Less control More control More locations Fewer locations Less secure? More secure?
- 15. X-aaS Anything as aService • IaaS • PaaS • SaaS
- 16. IaaS / PaaS/ SaaS
- 17. IaaS / PaaS/ SaaS
- 18. IaaS vendors • Amazon Web Services • Rackspace Cloud • GoGrid • Windows Azure? (*) – VM Role • Google Storage for Devs • Open IaaS standards: – OpenStack – Ecalyptus
- 19.
- 20. PaaS vendors • Windows Azure - .NET (and others) • Google App Engine – Python, Java • Heroku (Salesforce) – Ruby/Rails, node.js • Engine Yard – Ruby/Rails • DotCloud – almost anything • no.de – node.js • ep.io, gondor.io – Python/Django • AppHarbor - .NET • CloudFoundry (VMware) – Open-source PaaS – Java/Spring, Ruby/Rails, MongoDB, etc. • RedHat – Open(?)source

- 29. AWS Free tier •Amazon offers new AWS customers with a bundle of services free each month of their first year: – 750 hours of EC2 running Linux Micro instance usage – 750 hours of ELB plus 15 GM data processing – 10 GB of Amazon EBS plus 1 million IOs, 1GB snapshot storage, 10,000 snapshot Get Requests and 1,000 snapshot Put Requests – 15 GB of bandwidth in and 15 GB of bandwidth out aggregated across all AWS services
