Cloud Computing: Amazon AWS and EC2

@TeamSkunkworksvn Cloud Computing: Building an Infrastructure with Amazon AWS and EC2Chris Dollmont@MrCerulean

Agenda• Cloud Compu7ng Overview• Why?• How?• Discipline• Tools• Concept 2

Overview• What is the “Cloud”?• Where is it?• Who provides it? – Amazon – Rackspace – GoGrid – In house cloud 3

Overview• Amazon Services alphabet soup – EC2 (Elas7c Compute Cloud) – S3 (Simple Storage Service) – EBS (Elas7c Block Storage) – ELB (Elas7c Load Balancing) – SimpleDB – RDS (Rela7onal Database Service) – Route 53 (Elas7c DNS) – CloudWatch 4

Why?• Reduce hardware costs• Management• Ease of Deployment• Management• Scalability 5

Why not?• Reducing costs – bandwidth – cycles – storage – instances• Simplifying management – upfront investment 6

How?• Create an Amazon Web Services account – provide your credit card details• Launch an instance – Hundreds of publicly available instances – Linux, Windows, Solaris, BSD• Conﬁgure storage – S3 or EBS• Conﬁgure access 7

Discipline• Best prac7ces are cri7cal – Standard images – Standard tools – Deﬁne conven7ons• Support or not? – Paid support – Community support 8

Discipline• Moving to the cloud – Get your meatspace in order – Create your own AMI (image) – Use sane defaults• Test – And test – And test some more 9

Discipline• Loca7on, loca7on, loca7on – Be aware of latency – Amazon oﬀers many loca7ons (regions) • US East • US West • EU (Ireland) • Asia/Paciﬁc (Singapore) 10

Discipline• Decide on image availability – Reserved instances – Spot instances – On demand instances• Tie storage to an instance – Only when necessary• Create with transience in mind 11

Tools• Web based – Amazon’s AWS console • Free • Full featured – Rightscale • Not free • Excellent for full automa7on – SCALR • Not free • Excellent for full automa7on 12

Tools• Elas7fox – Graphical – Firefox based – 80%• Tim Kay’s aws tools – Command line – hep://www.7mkay.com/aws/ – scriptable (key!) 13

Tools• boto – Python based – hep://code.google.com/p/boto/ – command line – scriptable• mr.awsome – Python based – Uses boto – hep://pypi.python.org/pypi/mr.awsome – command line – scriptable 14

Tools• puppet – conﬁgura7on management• ZenOSS – system monitoring• ﬂume – log aggrega7on• fabric – code deployment 15

Concept• Base AMI – Built on Debian Lenny – Stripped to the minimum – puppet client installed• Start new AMI – Assign a class – Authen7cate to puppet – Go get coﬀee 16

Concept• puppet – installs packages based on class – sets up conﬁgura7on – adds users and groups – sets up ssh auth – starts essen7al services 17

Concept• ZenOSS – Can autodiscover new hosts – Hosts can be grouped by func7on – Monitoring and stats gathering• ﬂume – Centralizes logs – Allows for analysis 18
