What is cloud computing?
  • 5th generation of computing

1970s 1980s 1990s 2000s 2009+

Monolithic Client-Server Web SOA Cloud Services

slide10
Growing interest in cloud computing
  • Increasing number of outages

Google Insight for Search: Cloud Computing

Jul 08: Amazon S3 down 8.5h due to one single bit flip in Gossip message

Outage in:

Oct 09: MS Azure down 22h due to malfunction in the hypervisor

Apr 11: Amazon EC2 US East down 4 days due to Network problem and replicas algorithm

Feb 11: 40K Gmail Account down 4 days due to a bug in a storage software update

2007

2008

2009

2010

2011

Providing a higher level of reliability and availability is one of the biggest challenges of Cloud computing

slide11
Incidents with Cloud Computing
  • - Providers:
    • “I discovered that several systems on the Amazon EC2 network were preforming brute force attacks, against our VoIP servers.”[1]
    • “Complaints of rampant SIP Brute Force Attacks coming from servers with Amazon EC2 IP Addresses cause many admins to simply drop all Amazon EC2 traffic.”[2]
    • No guarantee that providers will financially survive. What will happen if your provider liquidates? “Cassatt, the San Jose, Calif.-based provider of cloud computing environments, has sold its assets to public IT management firm CA for an undisclosed sum. ”[3]
  • - Attacks:
    • BitBucket, DDoS’s Off The Air. “Starting Friday evening, our network storage became virtually unavailable to us, and the site crawled to a halt.”[4]
slide12
Incidents with Cloud Computing
  • - Maintenance:
    • Maintenance Induced Cascading Failures. “Gmail\'s web interface had a widespread outage earlier today, lasting about 100 minutes”[5]
  • - Storage:
    • T-Mobile: we probably lost all your Sidekick data “Well, this is shaping up to be one of the biggest disasters in the history of cloud computing, and certainly the largest blow to Danger and the Sidekick platform: T-Mobile\'s now reporting that personal data stored on Sidekicks has "almost certainly has been lost as a result of a server failure at Microsoft/Danger."”[6]
  • - Power:
    • Lightning Strike Triggers Amazon EC2 Outage “Some customers of Amazon’s EC2 cloud computing service were offline for more than four hours Wednesday night after an electrical storm damaged power equipment at one of the company’s data centers[7]
