We are entering the golden age of machine learning, and it’s all about the data. As the quantity of data grows and the costs of compute and storage continue to drop, the opportunity to solve the world’s biggest problems has never been greater. Our customers already use advanced machine learning to build self-driving cars, provide better care to newborns in the hospital , stop financial crimes and combat cyber threats. But this is clearly just the beginning.  
At Cloudera, we’re constantly working to help customers push the boundaries of what’s possible with data. Today, we’re excited to introduce Cloudera Data Science Workbench, which enables fast, easy, and secure self-service data science for the enterprise. It dramatically accelerates the ability of teams to build, scale, and deploy machine learning and advanced analytics solutions using the most powerful technologies.  
In this post, we’ll summarize our motivations for building Data Science Workbench, currently in private beta, and provide an overview of its capabilities.

## Data Scientists: A Thousand Questions, A Thousand Tools ##

Over the past few years, enterprises have adopted big data solutions for a huge variety of business problems. At the same time, though, data scientists struggle to build and test new analytics projects as fast as they’d like, particularly at large scale in secure environments.  
On the one hand, this is not surprising. Most analytics problems are not cookie-cutter. Data in the enterprise is complex. The questions data scientists ask often require advanced models and methods. Building a sustained competitive advantage or having a transformational impact using data requires experimentation, innovation, and hard work.  
Yet it should only be as hard as the problem, and no harder. Too often, technical and organizational constraints limit the ability of data scientists to innovate. Why is this?  
To begin, we need to understand who data scientists really are. According to typical big data industry marketing, a data scientist is equal parts an expert in statistics, machine learning, and software engineering, with solid business domain expertise to match. That’s a vanishingly rare combination of skills.  
It turns out, though, that many organizations already employ statisticians, quantitative researchers, actuaries, and analysts. These real-world data scientists often aren’t software engineers, but are quite comfortable with mathematics and the business domain. Rather than program Apache Hadoop and Apache Spark using Java or Scala, they typically work with small-to-medium data on their desktops, increasingly relying on open data science tools like Python, R, and their respectively vast ecosystems of libraries and frameworks for data cleansing, analysis, and predictive modeling.  
This presents several challenges, including:  
\- Every team, user, and project may require a different language, library, framework, or algorithm (e.g. Python vs R, Python 2.7 vs. 3.5). Meanwhile, collaboration and compliance depend on reproducibility, which is doubly hard with so many combinations.  
\- What works on a single machine may not scale across a cluster. Most data scientists typically work on samples and extracts.  
\- Secured clusters are challenging for data scientists. Not many statisticians are familiar with Kerberos authentication.  
The results is that for both technical and organizational reasons, data scientists are caught in a bind. They require flexibility and simplicity to be innovative and productive, but scale and security to impact the business.  
IT: Adoption vs. Compliance  
This puts IT in a tough spot. Data scientists are among the most strategic users in the organization. Their insights drive the business forward. Indeed, a common motivation for building an enterprise data hub is to support advanced analytics use cases. Since the business may depend on the results data scientists provide, IT teams are under tremendous pressure to make them productive.  
IT is responsible for compliance with corporate directives like security and governance. This is hard enough when every user is accessing your environment through a common interface, such as SQL. It becomes much harder when every team, user, and project uses a different set of open source tools. Managing so many environment permutations against a secured cluster is an unenviable, if not impossible, task. IT, forced to balance enterprise data security against the benefits of data science, is often forced to lock the data up and the data scientists out.  
As a result, data science teams are cut off from one of the enterprise’s most strategic assets. They remain on their desktops or adopt “shadow IT” cloud infrastructure where they can use their preferred tools, albeit on limited data sets. This usability gap limits innovation and accuracy for the data science team and increases cost and risk from fragmented data silos for IT.

## Introducing Cloudera Data Science Workbench ##

--------------------

A year ago, Cloudera acquired a startup, Sense.io, to help dramatically improve the experience of data scientists on Cloudera’s enterprise platform for machine learning and advanced analytics. The result of this acquisition and subsequent development is today’s announcement of Cloudera Data Science Workbench.  
Cloudera Data Science Workbench is a web application that allows data scientists to use their favorite open source libraries and languages — including R, Python, and Scala — directly in secure environments, accelerating analytics projects from exploration to production.  
Cloudera数据科学平台是一个web应用，允许数据科学家使用他们喜欢的开源库和语言，包括R，Python、Scala，整个操作在一个安全的环境中，加速从开发到生产的项目分析。

Built using container technology, Cloudera Data Science Workbench offers data science teams per-project isolation and reproducibility, in addition to easier collaboration. It supports full authentication and access controls against data in the cluster, including complete, zero-effort Kerberos integration. Add it to an existing cluster, and it just works.  
使用容器技术，Cloudera数据科学平台允许数据科学家团队项目隔离和重现，方便协作。他提供完整的认证和集群数据的访问控制，包括完整的零代价的Kerboeros集成。  
With Cloudera Data Science Workbench, data scientists can:  
• Use R, Python, or Scala on the cluster from a web browser, with no desktop footprint.  
• Install any library or framework within isolated project environments.  
• Directly access data in secure clusters with Spark and Impala.  
• Share insights with their team for reproducible, collaborative research.  
• Automate and monitor data pipelines using built-in job scheduling.  
使用Cloudera数据科学平台，数据科学家可以：  
（1） 直接在浏览器使用R、Python、Scala  
（2） 在独立的项目环境中安装库和框架  
（3） 使用Spark和Impala直接在安全集群访问数据  
（4） 团队之间分享可重现的、协作的研究  
（5） 使用内置的作业调度来自动化和检测数据管道

Meanwhile, IT professionals can:  
• Give their data science team the freedom to work how they want, when they want.  
• Stay compliant with out-of-the-box support for full platform security, especially Kerberos.  
• Run on-premises or in the cloud, wherever data is managed.  
We’re thrilled to announce Cloudera Data Science Workbench and look forward to sharing more information in the coming weeks.  
IT管理者可以：  
（1） 让数据科学团队自由灵活的工作  
（2） 保持完整的平台安全，尤其是Kerberos  
（3） 可以再本地也可以再云端执行。
