What is possible when you can consume compute resources on various hosting providers with nothing more than a python script? This talk will discuss Apache Libcloud, an Apache Incubator project dedicated to building standard interfaces into cloud computing.

Apache Libcloud is a unified interface into many popular cloud providers such as Amazon EC2, GoGrid, and Rackspace. Libcloud was created to address the problem that each cloud hosting provider provides a proprietary, slightly different, implementation of their API for accessing resources. Libcloud brings interoperability, visibility, and more importantly scriptability to many standard system administrator tasks.

In addition to providing APIs to manage servers, Libcloud is working on developing a portable Server Image format, so that identical machines can be created on any cloud provider, without a dependency on configuration management tools.

Hadoop, HBase, and friends are built from the ground up to support Big Data/NoSQL, but that doesn't make them easy. Just like with any other relatively new and complex technologies, there are some rough edges and growing pains to manage. I've learned some hard lessons while deploying HBase tables containing billions of rows and dozens of terabytes on OpenLogic's Hadoop infrastructure. Come to this session to learn about some of the "gotchas" you might run into when deploying Hadoop and HBase in your own private cloud and how to avoid them.

Ruby on Rails is a great framework for quickly building applications, but what happens when you are wildly successful and need to scale way up? This talk is a case study in the evolution of our Rails application from a monolithic "does everything" systems running on a hosted server to a service-oriented system running in the cloud. As part of this tale, we will also cover the migration from a single MySQL data store to an environment with sharded MySQL and several NoSQL variants. We will detail choices made along the way, the data used to make those choices, and distill the decision path down to a series of recommendations.

The audience will come away with concrete methods to scale their web applications and hints and heuristics to manage the evolution of their data.

Half of the pundits claim that The Cloud is the future. The other half warn us that Big Data is coming. Real engineers know these two don't always marry easily. How do we build systems that really scale, inside or outside the cloud? What conventional approaches don't work? What new approaches are available? What must we sacrifice from using them, and what do we gain in return? How do the economics really shake out? What does the CAP theorem really mean? Which things you've heard about the cloud are just hype, and which are really revolutionary?

The concept of cloudbursting is very appealing. Who wouldn't want to maximize control and minimize costs by running a few servers in-house and borrowing public cloud resources when the odd demand spike occurs? This arrangement is particularly appealing if you already have a reason to run at least part of your system in-house, like Big Data that would cost a fortune to store in the public cloud. Unfortunately, the implementation is not so straightforward. You have to keep two asynchronous systems in lockstep across the public Internet while ensuring security, handling unpredictable latency, and optimizing for data locality. Come to this session to learn how this can actually work with Amazon EC2 and SQS. The implementation is based on Ruby on Rails and Resque/Redis, but the concepts are broadly applicable.

Cloudant was born of a desire to make scalable data storage and analysis simple, both for users and administrators. This talk will focus on the technologies and processes that have proven instrumental in the pursuit of that vision. Adam will discuss local storage engines that are insensitive to system crashes and distributed databases that remain available during network partitions. He'll describe the Erlang VM's code upgrades and how they can be leveraged for rapid, low-impact deployments via continuous integration and configuration management, and he'll draw on years of operational experience to present pitfalls encountered and lessons learned.

SimpleGeo provides hosted services for location-aware applications, one of which is a cloud spatial database. One can make puns and jokes about "a cloud within a cloud" until blue in the face, but the reality of the matter is that accomplishing such a thing is a non-trivial technical endeavor. Designing for failure is a hard requirement by definition, which turns out to be a blessing in disguise.

The competitive features of our database include built-in scaling, high availability and data redundancy. Come hear how we are harnessing various open source software and cloud services to back up the promises made to our customers and allow them to store and query their data, big and small, without worrying about what's happening behind the scenes; we've built an infrastructure that has the cloud mentality of a flexible, reliable, and highly available service baked in at every layer and have stumbled on something completely unexpected at almost every step of the way.

The talk will include a high-level overview of our infrastructure, as well as brief deepdives into pieces more specific to our usecase (including bits we've built out ourselves). We'll be sure to include juicy war stories about handling the frequent failures guaranteed by running on AWS and kernel-level issues we've encountered while running on virtual instances.

Opening Keynote: Test is Dead
Presented by Alberto Savoia

ABSTRACT

The way most software is designed, developed, and launched has changed dramatically over the last decade -- but what about testing? Alberto Savoia believes that software testing as we knew it is dead -- or at least moribund -- in which case we should stick a fork in it and proactively take it out of its misery for good. In this opening keynote of biblical scope, Alberto will cast stones at the old test-mentality and will try his darnedest to agitate you and convince you that these days most testers should follow a new test-mentality, one which includes shifting their focus and priority from "Are we building it right?" to "Are we building the right it?" The subtitle of this year's GTAC is "cloudy with a chance of tests," and if anyone can gather the clouds into a hurricane, it's Alberto -- it might be wise to bring your umbrella.

Alberto Savoia is Director of Engineering and Innovation Agitator at Google. In addition to leading several major product development efforts (including the launch of Google AdWords), Alberto has been a lifelong believer, champion, innovator and entrepreneur in the area of developer testing and test automation tools. He is a frequent keynote speaker and the author of many articles on testing, including the classic booklet "The Way of Testivus" and "Beautiful Tests" in O'Reilly's Beautiful Code. His work in software development tools has won him several awards including the 2005 Wall Street Journal Technical Innovator Award, InfoWorld's Technology of the Year award, and no fewer than four Software Development Magazine Jolt Awards.

ABSTRACT

In this session, we share our experiences for testing the Microsoft Translator (MT) service. Testing the translator service can be divided into two broad areas -- (1) Testing of the machine learning system that returns the translation answer and (2) the web service that serves translate requests running on the Microsoft cloud. The MT service offers translation in 36 different languages for users across the globe through UI and API. Testing the MT cloud service without user data would be like shooting in the dark. From a product standpoint, we need to answer questions like How do we prioritize languages for improvement? How do we divide resources in our data center for effective capacity distribution for the languages? From a test perspective we need to understand how the system is being used so that we can ensure that any new bits deployed will hold-up in production.

We will discuss the following three problems: Strategy for testing the machine learning system. How do you perform load testing for the translation service running in the cloud? How can one extend the role of test by completely skipping the 'opening bugs' step?

With Microsoft for the past seven years, Vishal Chowdhary is currently with the MSR - Machine Translation (MT) team where he is responsible for both performance and scale testing of the MT cloud service and the machine translation quality. In the past, he has been involved with BizTalk, .NET Framework Wf and Wcf, and the Windows Azure AppFabric teams where he owned test strategy, test framework design, and feature testing. Vishal is passionate about making testing simpler and more interesting by employing new testing strategies and processes that prevent defects from entering the product.

ABSTRACT

BidiChecker is a tool for the automated testing of web pages for errors in support of right-to-left (RTL) languages, also known as bidirectional (bidi) because they routinely include left-to-right items such as numbers and Latin-script words and phrases. Bidi support for a web page is a common requirement, even for pages in left-to-right scripts. Any page which accepts user input or displays multilingual content is likely to end up handling bidirectional text at some point, as it will eventually encounter data in Arabic, Hebrew or another RTL language. BidiChecker provides a Javascript API which can be easily integrated into an existing test suite. It also supports a browser bookmarklet which lets you run the checks manually on any web page and browse through the errors highlighted on the page. We'll talk a bit about common bidi bugs, then describe and demonstrate BidiChecker.

Yana Margolin joined Google in 2009. Since then she's been in charge of testing bidirectional text support implementation across various Google applications. Her focus includes promoting BidiChecker - an internally developed, open-sourced, automated tool for bidirectional text handling testing, as well as facilitating product development teams to switch from manual testing model to an automated one. Prior to Google, Yana was a QA Team Manager at WebCollage Israel LTD, a content syndication provider, who built the company's testing team from scratch.

Jason Elbaum has been at Google since 2008, where he develops infrastructure for supporting bidirectional languages. Before that he spent nine years at Motorola/Freescale Semiconductor. He has degrees in computer science from Princeton University and economics from the London School of Economics, and worked at Imperial College London as a research assistant in petroleum engineering (really!). Originally from suburban Washington, D.C., he now lives with his wife and two kids in Israel, where he umpires Little League baseball.

ABSTRACT

The world of building software is undergoing rapid changes with the shift from desktop applications to highly connected and ubiquitous applications served from the Cloud. The shift to the Cloud poses new challenges (eq: how do you run xUnit frameworks on PAAS?) and opportunities on how to test while also creating whole new ways of testing in general (eg: fuzz testing on hundreds of machines for little cost). This talk will focus on helping you understand the challenges and opportunities while separating fact from fiction. It's time to part the Clouds and understand what lies ahead.

ABSTRACT

Web Consistency Testing is a new form of automated Web testing that answers the simple question "does this page look the way it should?". Historically, the way a page looks has been relegated to the status of "design artifact" and as such, been treated as something that must be tested with human eyes. In my talk I present the results of research and development of an automated issue detection system that can be extended in numerous dimensions to detect cross-browser rendering issues, CSS regressions, and i18n differences. Using the simplest representation possible, the "golden copy" of a page, this system requires no site-specific programming, making Web Consistency Testing available to every person in an organization, from product manager to QA engineer.

Kevin is the founder of Mogotest, a Web Consistency Testing service that aims to change the way we test Web sites and applications and simultaneously make testing available to all. He's been involved with many open source projects over the years, most notably the Apache Cayenne and Tapestry projects, Selenium, svn2git, and the rubber Capistrano plugin for cloud provisioning and deployment of Ruby applications. He is an Apache Software Foundation member and the current maintainer of the Selenium Grid project.

ABSTRACT

Google has a unique infrastructure for running web tests. This talk will focus on how this infrastructure evolved, from running tests on local machines, all the way up to the sophisticated tools available for Googlers now. Along the way, you'll learn how you, too, can build something similar using OSS, and a little bit of elbow grease. You'll walk away knowing just how much effort you want to expend on running your tests in the cloud, and whether a private or public implementation is the right thing for you.

Simon Stewart lives in London and works as a Senior Software Engineer in Test at Google. He is the current lead of the Open Source Selenium project and deeply involved with browser automation at work. Simon's first GTAC experience was in New York, where his carefully planned demo went horribly awry. It has been said before that Simon enjoys beer and writing better software, sometimes at the same time. This continues to be true. He is also the top hit for the search 'steel cage knife fight', a fact that makes him inordinately proud.

ABSTRACT

Today's test engineering is labor intensive, requires expensive switches in context, involves so much grunt work that it stifles creativity and slows down productivity, and, finally, it often ignores product and customer risks. Come and learn about the latest Google has to offer in open source test tools that help manual testers by eliminating much of the grunt work, keeping them focused on testing, and helping them prioritize their efforts based on risk. Chief among these are BITE, Quality Bots, Test Analytics, and Script Cover, the first two of which are the focus of this talk.

Ibrahim is an engineering manager at Google leading a team dedicated to building next-generation test tools for the web. Earlier he was a software engineer building developer tools used across the company. Prior to Google, Ibrahim was at Microsoft where he led tools and QA teams in Bing and SQL Server. His academic background includes extensive graduate-level work in software testing at the Florida Institute of Technology.

ABSTRACT

Angular teaches your old browser new tricks. It is what HTML would have been had it been designed for building web-applications. Angular is radical because it eliminates boilerplate code with declarative rather than imperative syntax.

Angular:
* Allows you to create custom HTML elements and attributes that provide dynamic behavior
* Declaratively describe web-applications behavior with little JavaScript.
* Creates an environment that provides trivially reusable widgets, data-binding, "automatic MVC", server resources, and other primitives useful in building AJAX apps.
* Builds apps that have orders of magnitude less JavaScript than equivalent apps written in classical way.
* Eliminates waiting on compiling for UI changes.

Having an awesome framework is not enough, one needs to also have an awesome testability story. In this session we will focus on all of the work which we have done to make applications written in Angular a joy to test.

Misko Hevery works as an Agile Coach at Google where he is responsible for coaching Googlers to maintain the high level of automated testing culture. This allows Google to do frequent releases of its web applications with consistent high quality. Previously he worked at Adobe, Sun Microsystems, Intel, and Xerox (to name a few), where he became an expert in building web applications in web related technologies such as Java, JavaScript, Flex and ActionScript. He is very involved in Open Source community and an author of several open source projects such as Angular (http://angularjs.org) and JsTestDriver (http://code.google.com/p/js-test-driver).

We present our experience designing, implementing, and deploying a Node.js-based distributed system for analyzing system and application performance across a datacenter. Our system's design, and particularly the choice of programming environment, were driven by our goals of supporting real-time analysis of problems spanning hundreds of production systems, which requires that the system deal with large volumes of data with very low latency. We will briefly discuss these considerations and why we chose Node.js for the implementation. We will then present our actual experience building and deploying the software, including topics of software development speed; availability of libraries and tools for development, testing, and verification; difficulties observing and debugging Node applications (especially post-mortem); packaging issues related to lack of C++ binary compatibility; and other development and deployment issues. Finally, we will close with a demonstration of the facility itself, and some discussions of the production pathologies that it has found—including the results of using the facility to analyze its own performance.

Summary

Software architecture has become heavily influenced in recent years by the largest software system in the world: The Web. While the foundations of much of what we understand about software architecture haven't changed, the living laboratory of the Web has created a steady and impressive stream of innovations and ideas that are just now being fully appreciated. Questions such as how to design our systems, which methods are best to make them composable and extensible, how much of an architecture should be pliable and who should be able to influence it are all subjects for which the modern era of the Web has offered up compelling and often startling new approaches.

This session will take a comprehensive look at how the "Web as Platform", one of the foundational concepts of the Web 2.0 era, is changing the discipline and practice of software architecture in important and significant ways that architects and technical leads must know today. Not just an exercise in examination of current trends, attendees will take away useful and immediately applicable methods for improving and extending the discipline of software architecture with Web approaches that can put to work in the enterprise or anywhere else.

Hadoop, the open-source implementation of MapReduce, provides unprecedented opportunities for both research and education. On the research side, academics are now able to explore problems at scale with modest resource investments, either with inexpensive commodity clusters or through utility computing services. On the education side, Hadoop provides a nice vehicle to teach students about large-scale distributed processing.

In this talk, I will present "cloud computing" activities at the University of Maryland, in collaboration with Google/IBM under the Academic Cloud Computing Initiative and in partnership with Amazon Web Services. Efforts include semester-long Hadoop courses, as well as research projects in text processing and bio-informatics. I will specifically focus on my attempts to integrate research with education, to the benefit of both.

Jimmy Lin is an Associate Professor in the iSchool at the University of Maryland, with affiliations in the Department of Computer Science and the Institute for Advanced Computer Studies, as well as the National Center for Biotechnology Information (NCBI), National Library of Medicine (NLM), the National Institutes of Health (NIH). He received a Ph.D. in Electrical Engineering and Computer Science from MIT in 2004. Dr. Lin's research primarily lies at the intersection of information retrieval and natural language processing, but his interests extend to human-computer interaction, bio-informatics, medical informatics, and large-scale distributed systems.

Cloud computing and its predecessors, grid and utility computing, all address shared, on-demand computing at scale. To achieve sufficient scale to amortize costs, cloud computing emphasizes saving human time through 1) automated management, 2) easier programming using systems like MapReduce and Hadoop, and 3) shared and open access.

Existing architectures for achieving these goals are composed of largely isolated resource allocation sub-systems (e.g., for MapReduce scheduling, virtualization, CPU, network bandwidth, power, etc.) These sub-systems have global impact, but local visibility, which can cause them to work against each other. The shared, open nature of cloud computing systems requires balancing the need to do efficient local allocation of resources and the need to regulate and differentiate applications globally.

We take a clean slate approach to designing a cloud computing architecure. We apply economic mechanisms to resources at every layer from the high-level Hadoop system through the allocation of virtualized resources to physical servers. We find that this approach 1) simplifies system design, 2) provides more high-level optimization opportunities, 3) provides greater control over predictability, and 4) increases overall application utility.
