Hadoop and Realtime Cloud Computing

Architectures such as MapReduce and Hadoop are good for batch processing of big data, but bad for realtime processing

Big data is creating a massive disruption for the IT industry. Faced with exponentially growing data volumes in every area of business and the web, companies around the world are looking beyond their current databases and data warehouses for new ways to handle this data deluge.

Taking a lead from Google, a number of organizations have been exploring the potential of MapReduce, and its open source clone Hadoop, for big data processing. The MapReduce/Hadoop approach is based around the idea that what's needed is not database processing with SQL queries, but rather dataflow computing with simple parallel programming primitives such as map and reduce.

As Google and others have shown, this kind of basic dataflow programming model can be implemented as a coarse-grain set of parallel tasks that can be run across hundreds or thousands of machines, to carry out large-scale batch processing on massive data sets.

Google themselves have been using MapReduce for batch processing for over six years, and others, such as Facebook, eBay and Yahoo have been using Hadoop for the same kind of batch processing for several years now. So today, parallel dataflow is firmly established as an alternative to databases and data warehouses for offline batch processing of big data. But now the game is changing again...

In recent months, Google has realized that the web is now entering a new era, the realtime era, and that batch processing systems such as MapReduce and Hadoop cannot deliver performance anywhere near the speed required for new realtime services such as Google Instant. Google noted that

  • "MapReduce isn't suited to calculations that need to occur in near real-time"

and that

  • "You can't do anything with it that takes a relatively short amount of time, so we got rid of it"

Other industry leaders, such as Jeff Jonas, Chief Scientist for Analytics at IBM, have made similar remarks in recent weeks. In his recent video "Big Thoughts on Big Data", Jonas notes that with only batch processing tools to handle it, organizations grappling with a relentless avalanche of realtime data will get dumber over time rather than getting smarter.

  • "The idea of waiting for a batch job to run doesn't cut it. Instead, how can an organization make sense of what it knows, as a transaction is happening, so that it can do something about it right then"
  • "I'm not a big fan of batch processes... I've never seen a batch system grow up an become a realtime streaming system, but you can take a realtime streaming system and make it eat batches all day long"
  • "I like Hadoop but it's meant for batch activities. That's not the kind of back-end you would use for realtime sense-making systems"

So coarse-grain dataflow architectures such as Hadoop are good for batch, but bad for realtime.

To power realtime big data apps we need a completely new type of fine-grain dataflow architecture. An architecture that can, for example, continuously analyze a stream of events at a rate of say one million events per second per server, and deliver results with a maximum latency of five seconds between data in and analytics out. At Cloudscale we set out to crack this major technical problem, and to build the world's first "realtime data warehouse". The linearly scalable Cloudscale parallel dataflow architecture not only delivers game-changing realtime performance on commodity hardware, but also, as Jeff Jonas notes above "can eat batches all day long" like a traditional MapReduce or Hadoop architecture. There isn't really an established name yet for such a system. I guess we could call it a "Redoop" architecture (Realtime Dataflow on Ordinary Processors, or Realtime Hadoop).

Cloud Expo Breaking News
Next-Gen Cloud. Whatever you call it, there’s a higher calling for cloud computing that requires providers to change their spots and move from a commodity mindset to a premium one. Businesses can no longer maintain the status quo that today’s service providers offer. Yes, the continuity, speed, mobility, data access and connectivity are staples of the cloud and always will be. But cloud providers that plan to not only exist tomorrow – but to lead – know that security must be the top priority for the cloud and are delivering it now. In his session at 14th Cloud Expo, Kurt Hagerman, Chief Information Security Officer at FireHost, will detail why and how you can have both infrastructure performance and enterprise-grade security – and what tomorrow's cloud provider will look like.

The revolution that happened in the server universe over the past 15 years has resulted in an eco-system that is more open, more democratically innovative and produced better results in technically challenging dimensions like scale. The underpinnings of the revolution were common hardware, standards based APIs (ex. POSIX) and a strict adherence to layering and isolation between applications, daemons and kernel drivers/modules which allowed multiple types of development happen in parallel without hindering others. Put simply, today's server model is built on a consistent x86 platform with few surprises in its core components. A kernel abstracts away the platform, so that applications and daemons are decoupled from the hardware. In contrast, networking equipment is still stuck in the mainframe era. Today, networking equipment is a single appliance, including hardware, OS, applications and user interface come as a monolithic entity from a single vendor. Switching between different vendor'...
More and more enterprises today are doing business by opening up their data and applications through APIs. Though forward-thinking and strategic, exposing APIs also increases the surface area for potential attack by hackers. To benefit from APIs while staying secure, enterprises and security architects need to continue to develop a deep understanding about API security and how it differs from traditional web application security or mobile application security. In his session at 14th Cloud Expo, Sachin Agarwal, VP of Product Marketing and Strategy at SOA Software, will walk you through the various aspects of how an API could be potentially exploited. He will discuss the necessary best practices to secure your data and enterprise applications while continue continuing to support your business’s digital initiatives.
You use an agile process; your goal is to make your organization more agile. What about your data infrastructure? The truth is, today’s databases are anything but agile – they are effectively static repositories that are cumbersome to work with, difficult to change, and cannot keep pace with application demands. Performance suffers as a result, and it takes far longer than it should to deliver on new features and capabilities needed to make your organization competitive. As your application and business needs change, data repositories and structures get outmoded rapidly, resulting in increased work for application developers and slow performance for end users. Further, as data sizes grow into the Big Data realm, this problem is exacerbated and becomes even more difficult to address. A seemingly simple schema change can take hours (or more) to perform, and as requirements evolve the disconnect between existing data structures and actual needs diverge.
