Cloudera Releases Cloudera Director 2.0 Marked By Enhanced Operational Granularity And Automation Of Cloud-Based Hadoop Deployments

On Thursday, Cloudera today announced the release of Cloudera Director 2.0, the next version of Cloudera’s platform for deploying and managing Cloudera Enterprise within cloud environments. In collaboration with Cloudera Manager, Cloudera Director 2.0 empowers users to deploy CDH clusters within a cloud infrastructure by taking advantage of a combination of configuration scripts to collectively launch the CDH cluster, schedule queries, retrieve Hadoop-based data and terminate it when required. Moreover, Cloudera Director 2.0 gives customers the ability to add ETL and Modeling to workloads using spot instance support, thereby decreasing operational costs associated with hosting. This version also enables the launch and termination of clusters as result of the execution of specific jobs, thereby delivering enhanced automation regarding the management of cloud-based CDH clusters that correspondingly gives customers greater control over their deployments in addition to the opportunity to decrease costs. In addition, Thursday’s release features the ability to both clone and repair clusters with zero to minimal disruption to the deployment. Meanwhile, Cloudera’s beta RecordService for unified access control and security by means of a distributed data service supports “secure, multi-tenant access” to all users analyzing Hadoop data in Amazon S3 and other storage repositories for Hadoop data. By giving customers finely grained control regarding operational processes that include cluster launch, cluster termination, query management as well as improved scalability for business intelligence and analytic workloads, Cloudera Director 2.0 promises to entice customers to leverage the agility and economics of the public cloud to complement their on-premise Hadoop deployments. As the only Hadoop distribution that supports hybrid cloud environments, Cloudera empowers customers to nimbly deploy Hadoop workloads on Amazon Web Services, Google Cloud Platform or Microsoft Azure with nuanced and granular controls that collectively deliver optimized cost, greater operational control, improved scalability, enhanced automation and more robust security within their cloud deployments. Version 2.0 of Cloudera Director accelerates the industry-wide trend toward the convergence between cloud computing and Big Data by giving customers enterprise grade, self-service tools to manage their Hadoop workloads in the cloud, from within a single pane of glass.

Guest Blog Post: “SonarW: Making Big Data Easy Through NoSQL” By Ron Bennatan, Co-Founder Of jSonar Inc.

The following guest blog post was authored by Ron Bennatan, co-founder of jSonar Inc.

SonarW: An Architecture for Speed, Low Cost and Simplicity

SonarW is a purpose-built NoSQL Big Data warehouse and analytics platform for today’s flexible modern data. It is ultra-efficient, utilizing parallel processing and demanding less hardware than other approaches. Moreover, SonarW brings NoSQL simplicity to the Big Data world.

Key architectural features include:

  • JSON-native columnar persistence: This works well for both structured and unstructured data; data is always compressed; and can be processed in parallel for every operation.
  • Indexing and Partitioning: All data is indexed using patent-pending Big Data indexes.
  • Parallel and Distributed Processing: Everything is done in parallel-both across nodes and within a node to ensure small, cost effective clusters.
  • JSON Optimized Code: Designed from the ground up for efficient columnar JSON processing.
  • Lock-less Data Structures: Built for multi-thread, multicore, and SMID processing.
  • Ease of Use: SonarW inherits its ease of use and simplicity from the NoSQL world and is 100 percent MongoDB compatible. Big Data teams are more productive and can spend less time on platform and code.

Due to its key architectural advantages over today’s Big Data warehousing approaches, SonarW defers the need for large clusters and scales to any size but does not require an unreasonable number of nodes to perform workloads of other Big Data solutions. As a result, the platform reduces both hardware costs and the costs of managing these clusters.

Why is there a Need for a NoSQL Data Warehouse for Big Data Analytics?

Big Data implementations can be complex

Big Data is no longer a stranger to the IT world. All organizations have embarked on the Big Data path and are building data lakes, new forms of the Enterprise Data Warehouse, and more. But many of them still struggle to reap the benefits and some are stuck in the “collection phase”. Landing the data is always the first phase, and that tends to be successful; it’s the next phase, the usage phase-such as producing useful Big Data analytics – that is hard. Some call this the “Hadoop Hangover”. Some never go past the ETL phase, using the Data Lake as no more than an ETL area and loading the data back into conventional data stores. Some give up.

When these initiatives stall the reason is complexity. But while all this is happening, on the other “side” of the data management arena, the NoSQL world has perfected precisely that. Perhaps the main reason that NoSQL databases such as MongoDB has been so successful is the appeal to developers who find it easy to use and who feel they are an order of magnitude more productive than other environments.

Bringing NoSQL Simplicity to Big Data

So why not merge the two? Why not take NoSQL’s simplicity and bring it to the Big Data world? That was precisely the question we put to ourselves when we went out to build SonarW – a Big Data warehouse that has the look-and-feel of MongoDB, the speed and functionality of MPP RDBMS warehouses and the scale of Hadoop.

As in other NoSQL-based systems, many of the advantages stem from the nature of JSON documents. Javascript Object Notation (JSON) is a perfect middle ground between structure and flexibility. JSON has become ubiquitous and is considered to be the “lingua-franca” of Web, mobile applications, social media and IoT. JSON is,

  • Simple- but not simplistic.
  • Flexible- yet has enough self-describing structure to make it effective.
  • Structured – but one that is easy to work with, can express anything, and can bring the simplicity and flexibility that people love.

JSON is the fastest growing data format on earth – by a lot.  It is also the perfect foundation for Big Data where disparate sources need to quickly flow in and be used for deriving insight.

For SonarW, we started with JSON and asked ourselves how we can make it scale – and the answer was in compressed columnar storage of JSON coupled with rich analytic pipelines that can be executed directly on the JSON data. Everything looks like a NoSQL data pipeline similar to MongoDB or Google Dremel or other modern data flows, but they execute on an efficient columnar fabric and all without the need to define schema, to work hard to normalize data or to completely lose control without any structure.

Efficient scalability also reduces complexity

The other goal we set for SonarW is efficiency. Everything scales horizontally these days – and SonarW is no exception. But scaling horizontally allows one to hide inefficiencies. Throw enough hardware at anything and things go fast. But it also becomes expensive – especially in the enterprise where costs and charge-backs are high. We fondly refer to SonarW as “Big-but-Lean Data”. I.e. it’s good to scale, but it’s better to do it efficiently. As an example, the figure below shows the number of nodes and costs to run the Big Data benchmark on a set of platforms. All these systems achieved the same minimal performance scores (with RedShift and SonarW being faster than the others), but the size and cost of the clusters were different (in both charts, smaller is better).

NoSQL can optimize Big Data analytics success

A NoSQL approach has been shown to be a highly successful approach for Big Data OLTP databases as provided by companies such as MongoDB. However, no such capability has been available for Big Data analytics. SonarW was built, from the ground up – with a JSON columnar architecture – to provide a simple NoSQL interface along with MPP speeds and efficient scalability that optimizes the developer’s ability to deliver on Big Data analytics projects.

Big Data Benchmark: Breakthrough Cost and Performance Results

One of the benchmarks used for Big Data workloads is the “Big Data Benchmark,” which is run by the AMP lab at Berkeley. This benchmark runs workloads on representatives from the Hadoop ecosystem (e.g. Hive, Spark, Tex, etc), as well as from MPP environments. Note SonarW’s performance and cost in comparison to Tez, Shark, Redshift, Impala and Hive.

Cloudera Leads Initiative To Render Apache Spark Viable Alternative To MapReduce

Cloudera recently announced a One Platform Initiative that aspires to make Apache Spark the default framework for processing analytics in Hadoop, ahead of MapReduce. Cloudera’s One Platform Initiative will focus on bolstering the security of Apache Spark, rendering Spark more scalable, enhancing management functionality and augmenting Spark Streaming, the Spark component that focuses on ingesting massive volumes of streaming data for use cases such as the internet of things. Cloudera’s efforts to improve the security of Apache Spark will focus on ensuring the encryption of data at rest as well as over the wire. Meanwhile, the initiative to improve the scalability of Apache Spark aims to render it scalable to as many as 10,000 nodes including enhanced ability to handle computational workloads by means of an integration with Intel’s Math Kernel Library. With respect to management, Cloudera plans to deepen Spark’s integration with YARN by creating metrics that provide insight into resource utilization as well as improvements to multi-tenant performance. Regarding Spark Streaming, Cloudera plans to render Spark Streaming more broadly available to business users via the addition of SQL semantics and the ability to support 80% of common streaming workloads.

Cloudera’s larger goal is to enhance the enterprise-readiness of Apache Spark with a view to promoting it as a viable alternative to MapReduce. All of Cloudera’s enhancements to Spark will be contributed to the Apache Spark open source project. That said, Cloudera’s leadership in stewarding the acceleration of the enterprise-readiness of Apache Spark as a MapReduce alternative promises to position it strongly as the undisputed market share and thought leader in the Hadoop distribution space, particularly given the range of its intended contributions to Spark and the depth of its vision for subsequent Spark enhancements in forthcoming months.
