Elastic Architectures

A simplistic case…


Data Center Europe

Mitigate increasing loadwith horizontal scaling

• Manual interface to the Data Center

• Hardware provisioning process partly consists of human tasks– Hardware procurement– Hardware installation– Network configuration– …

Adding additional servers is a matter of days to weeks!

Infrastructure-as-a-Service Provider

• Self-service interface to the Data Center (Web Console, API)

• Virtual-Hardware provisioning is fully automated

Adding additional virtual servers is a matter of minutes!

Elastic Architecture with Auto Scaling

t1: Medium Load

Servers Nodes: 2

IaaS-Provider (AWS, …)

t2: High Load

=> Scale up!

Server Nodes:

t3: Low Load

=> Scale Down!

3. rds-authorize-db-security-group-ingress helloRdsSg --cidr-ip 188.63.186.153/32

AWS command line toolsCreate an new MySQL Database Server



1. echo "create database helloworlddb; use helloworlddb; create table message( mkey varchar(255), mval varchar(255)); insert into message(mkey,mval) values ('welcome','Hello from DB');" | mysql -u masteruser -pmasterpw1234 -h helloworlddb.….eu-west-1.rds.amazonaws.com

MySQL command line toolsCreate database and tables, import data

Not AWS specific

(standard mysql)



1. ec2-run-instances ami-c37474b7 -g helloSg -k myKey -t t1.micro

2. ec2-describe-instances i-3e15f174

AWS command line toolsCreate and start a new Linux Server(an EC2 instance based on Amazon Linux)



ssh -i myKey.pem ec2-user@$ec2-….amazonaws.com

1. sudo su -2. yum -y install tomcat73. cd /var/lib/tomcat7/webapps/4. wget http://sisetestbucket.….amazonaws.com/test.war5. chown tomcat:tomcat test.war6. cd /usr/share/tomcat7/conf/7. echo 'JAVA_OPTS="${JAVA_OPTS}
