Numbers first

Why do they work when we need them?

Pure luck?

Why do they work when we need them?

Why do they work when we need them?

Designed Developed

Why distributed?

Insufficient power for larger scale projects

Geographical regions simulation

Realistic results (end to end)

How can we do that?

Classic way Computer - lots of them, wires, routers, people, scripts, more computers an so on

Modern way Cloud, dedicated tools, dedicated environments

Solutions

Distributed on local infrastructure

Distributed on cloud

Dedicated cloud solutions

Combination between local and cloud

Distributed on local infrastructure

Firewalls on the systems are turned off Clients are on the same subnet Same version of JMeter on all the systems

and

1. go to jmeter/bin 2. execute jmeter-server.bat

Multiplies the script

on all Slaves

1. go to jmeter/bin2. open jmeter.properties3. edit “remote_hosts=“

Distributed on cloud

Dedicated cloud solutions

Combination between local and cloud

Best possible test results:- cloud agents provide a realistic simulation of

end-users - agents on the intranet can identify network-

related issues and bottlenecks

Advantages

“Team work”

Distributed resources

Large-scale tests are possible

Tests are more realistic and accurate

Cloud pro’s

Better geographical areas coverage No setup or maintenance required Easy and fast deployment Scalability: If you need more agents, just

launch them Easy management Low cost: Only pay for the time the agents

are running No limits

Disadvantages

Same configuration and resources should be kept for comparability

High costs of implementation and maintenance

Application under test must be Internet facing so that cloud agents can interact with it.

Cloud con’s

Conclusion

Do your magic before going live,

don't be a “Rio” example
