IT Operations “Be predictable – minimize risk”

Features & code changes

Development “Be more agile - deliver faster”

Agile Development DevOps

DevOps: Bringing Applications to Market Faster Principles and processes for enhancing collaboration, communications and integration between software developers and IT Operations to rapidly produce/update applications and cloud services


Continuous Delivery: reliable software releases through build, test, and deployment automation Techniques such as automated testing, continuous integration and continuous deployment allow software to be developed to a high standard and easily packaged and deployed

Assumes the lab is ready. Somehow….

The regular process

Report Run test Build ready


What about the lab?

But the truth is...

But we know the challenges:

• Who will setup the lab?

• How long will it take? What type of paperwork/processes?

• Do you have the infrastructure?

• What if you want to set it up on the Public/Private Cloud with various vendors?

Report Run test Setup lab Build ready


What about the application build?

And to take it further…

We know the challenges:

• Do you know when the build will be ready?

• Is it set up correctly?

• Is the process repeatable?

• What happens to the lab after testing is done?

Benefits

Lab management automation

• Manage your own lab

• Provision hardware – physical or virtual

• Use various cloud vendors as needed

• Error-proof deployment

• Model can be ported between various stages

• Virtualization of service


The challenges today

• What are the requirements?

• Am I testing the right things?

• What should the SLOs be?

• How can I build scripts faster?

• How can I set up the monitors faster?

• How do I recreate production issues in testing?

• …..

• What are the requirements?

• Am I monitoring the right things?

• What should the SLAs be?

• How can I build scripts faster?

• How can I set up the monitors faster?

• …..

Test vs. production

Test Production


The answer lies in

How can Ops help me test the right things?

How can Testing help me maintain app quality?

Collaboration—changing the way they think

Test Production


Process flow guides users through the process

Step by step flow

Refine load test details

Collect & analyze production data Load test Analyze load

test data Compare production and load test data


Collaboration through HP Performance Center

Leverage data from production: Production usage information from • BSM, RUM, WebTrends, server logs, etc

Scripts • From synthetic Business Process Monitoring (BPM)

• From live sessions - Real User Monitoring (RUM)

Monitoring information • SiteScope profiles

To make performance testing: • More realistic

• Scenarios based on production usage

• More accurate

• Test results compared with production

• More reliable

• Data sharing, improves results with each testing cycle

Continuous delivery of application performance


DevOps—collaboration and quality

Benefits

• Make sure you are testing the right things

• Get better requirements

• Accelerate testing efforts

• Make testing more accurate

Collaborate towards a common objective—quality


Release process is too long

Challenges • Provisioning and deployment processes are time-consuming

• Manual processes are error-prone.

• Different tools and processes for each stage

• Manual creation and hand-off of deployment docs and checklists

• “it works on my machine”

Release management • Define application release cycle

• Establish stage release criteria

• Create release approval process

• Support multiple, simultaneous releases

Automated deployment • Infrastructure provisioning

• Application deployment

• Integrated monitoring

• Traditional IT, managed services, private cloud or public cloud

• Physical or virtual environments


Improve Application Deployment Quality

• Reduce people and process errors through automation

• Ensure consistency of deployment

• Leverage knowledge across stages

• Increase test coverage with additional testing

Achieve application deployment success rates as high as 95%*

“Went from 20%-30% failure rates to 0.15% failure rates for application release processes under automation”

“Prior to automation, applications would be deployed slightly differently across each server. With automation, there is consistency and control”
