Scaling Your Applications: Performance, Testing and Tuning for Millions of Users

Cloud Mafia is back for another great event!

Come meet old friends and make some new ones as we heat up the summer SF style.

We have two amazing speakers from AdRoll and Netflix focusing on application performance and tuning for billions of requests and millions of end-users. 

Thank-you to our hosts and sponsors: AdRoll and O'Reilly for helping support this great event!  

Food and drinks will be provided.  Come to meet other developers and cloud professionals, network and learn from industry leaders. 

Please RSVP on Meetup page.

Agenda: 

6-7pm Networking & Food

7-8pm Tech Talks

8-9pm Networking 

Speakers: 

Ariel Tseitlin, Director, Cloud Solutions, Netflix

Resiliency Through Failure 

Netflix created a suite of tools, collectively called the Simian Army, to improve resiliency and maintain the cloud environment.   In the typical case, failure modes are corner cases which are poorly, if at all, tested. It’s only by failing often that we can ensure that we are resilient to failure. We look for ways to induce failure in our production environment to better prepare us for the inevitable failures that will occur. We’ve open sourced some of the monkeys (Chaos, Janitor, Conformity), and are working on releasing the rest. The presentation will cover the reason for creating each monkey, what we’ve been able to learn from running them, and tips for those interested in adopting the approach. Chaos Monkey randomly terminates virtual machines to ensure that services are resilient to node failure. Chaos Gorilla is a more powerful version of Chaos Monkey, terminating an entire AWS Availability Zone (data center) to ensure resiliency to a single zone failure. Latency Monkey induces random network delays and errors to ensure that services are resilient to degradation in their dependencies. Janitor Monkey is the cloud cleaning crew. It prevents clutter by cleaning up old and unused resources.


James Kelly, Senior Software Engineer, AdRoll 


Hot Sauce for Your Service

AdRoll's Real Time Bidding servers need to reply to billions of
requests each day, each of them within 100ms or less. In order to
develop and tune these machines we've had to load test all of our
systems multiple times and continuously. This presentation will
discuss AdRoll's open source load testing tool, Habanero. It will
cover the origins of the project: why we implemented it and how it
compares with other load test frameworks, e.g. JMeter, tsung. It will
cover the internals of the application including how request are
generated and collection of telemetry data. A brief tangent into the
implementation language, Erlang, will focus on the advantages of
Erlang's concurrency model. We will conclude with a demonstration of
load test on an example web service. A sample load test scenario will
be created and run against a live instance. Instructions on how to
construct Habanero workers via a public AWS AMI will be provided.


Cheers,

Inga

    Thanks to all the folks at CloudMafia, AdRoll, and Netflix!

    Please reach out to begin evaluating the The SOASTA Platform for real-time Performance / Load Testing apps using HTTP/HTTPs and web services based on SOAP & REST. Gartner and IDC recently rated SOASTA as a Leader in the testing sector recently and our clients include 7 of the top 10 largest online retailers in the US. A POC delivered at no charge is on the table now for a proper evaluation if that's of interest to any Cloud Mafia participant that's not already a SOASTA client.
