Introduction: Update: MapReduce and PageRank Notes from Remzi Arpaci-Dusseau's Fall 2008 class . Collects interesting facts about MapReduce and PageRank. For example, the history of the solution to searching for the term "flu" is traced through multiple generations of technology. With Google entering the cloud space with Google AppEngine and a maturing Hadoop product, the MapReduce scaling approach might finally become a standard programmer practice. This is the best paper on the subject and is an excellent primer on a content-addressable memory future. Some interesting stats from the paper: Google executes 100k MapReduce jobs each day; more than 20 petabytes of data are processed per day; more than 10k MapReduce programs have been implemented; machines are dual processor with gigabit ethernet and 4-8 GB of memory. One common criticism ex-Googlers have is that it takes months to get up and be productive in the Google environment. Hopefully a way will be found to lower the learning curve a

Introduction: Update 2: Sorting 1 PB with MapReduce . PB is not peanut-butter-and-jelly misspelled. It's 1 petabyte or 1000 terabytes or 1,000,000 gigabytes. It took six hours and two minutes to sort 1PB (10 trillion 100-byte records) on 4,000 computers and the results were replicated thrice on 48,000 disks. Update: Greg Linden points to a new Google article MapReduce: simplified data processing on large clusters . Some interesting stats: 100k MapReduce jobs are executed each day; more than 20 petabytes of data are processed per day; more than 10k MapReduce programs have been implemented; machines are dual processor with gigabit ethernet and 4-8 GB of memory. Google is the King of scalability. Everyone knows Google for their large, sophisticated, and fast searching, but they don't just shine in search.

Introduction: The Google Operating System blog has an interesting post on Google's scale based on an updated version of Google's paper about MapReduce. The input data for some of the MapReduce jobs run in September 2007 was 403,152 TB (terabytes), the average number of machines allocated for a MapReduce job was 394, while the average completion time was 6 minutes and a half. The paper mentions that Google's indexing system processes more than 20 TB of raw data. Niall Kennedy calculates that the average MapReduce job runs across a $1 million hardware infrastructure, assuming that Google still uses the same cluster configurations from 2004: two 2 GHz Intel Xeon processors with Hyper-Threading enabled, 4 GB of memory, two 160 GB IDE hard drives and a gigabit Ethernet link. Greg Linden notices that Google's infrastructure is an important competitive advantage. "Anyone at Google can process terabytes of data. And they can get their results back in about 10 minutes, so they ca

Introduction: If Google was a boxer then MapReduce would be a probing right hand that sets up the massive left hook that is  Dremel , Google's—scalable (thousands of CPUs, petabytes of data, trillions of rows), SQL based, columnar, interactive (results returned in seconds), ad-hoc—analytics system. If Google was a magician then MapReduce would be the shiny thing that distracts the mind while the trick goes unnoticed. I say that because even though Dremel has been around internally at Google since 2006, we have not heard a whisper about it. All we've heard about is MapReduce, clones of which have inspired entire new industries. Tricky . Dremel, according to Brian Bershad, Director of Engineering at Google, is targeted at solving BigData class problems : While we all know that systems are huge and will get even huger, the implications of this size on programmability, manageability, power, etc. is hard to comprehend.

Introduction: Misco: A MapReduce Framework for Mobile Systems  is a very exciting paper to me because it's really one of the first explorations of some of the ideas in  Building Super Scalable Systems: Blade Runner Meets Autonomic Computing in the Ambient Cloud . What they are trying to do is efficiently distribute work across a set cellphones using a now familiar MapReduce interface. Usually we think of MapReduce as working across large data center hosted clusters. Here, the cluster nodes are cellphones not contained in any data center, but compute nodes potentially distributed everywhere. I talked with Adam Dou , one of the paper's authors, and he said they don't see cellphone clusters replacing dedicated computer clusters, primarily because of the power required for both network communication and the map-reduce computations. Large multi-terabyte jobs aren't in the cards...yet. Adam estimates computationally that cellphones are performing similarly to desktops of ten years ago. Instead, they

Introduction: Disco is an open-source implementation of the MapReduce framework for distributed computing. It was started at Nokia Research Center as a lightweight framework for rapid scripting of distributed data processing tasks. The Disco core is written in Erlang. The MapReduce jobs in Disco are natively described as Python programs, which makes it possible to express complex algorithmic and data processing tasks often only in tens of lines of code.

5 0.78256637 912 high scalability-2010-10-01-Google Paper: Large-scale Incremental Processing Using Distributed Transactions and Notifications

Introduction: This paper,  Large-scale Incremental Processing Using Distributed Transactions and Notifications  by Daniel Peng and Frank Dabek, is Google's much anticipated description of Percolator, their new  real-time indexing  system. The abstract: Updating an index of the web as documents are crawled requires continuously transforming a large repository of existing documents as new documents arrive. This task is one example of a class of data processing tasks that transform a large repository of data via small, independent mutations. These tasks lie in a gap between the capabilities of existing infrastructure. Databases do not meet the storage or throughput requirements of these tasks: Google’s indexing system stores tens of petabytes of data and processes billions of updates per day on thousands of machines. MapReduce and other batch-processing systems cannot process small updates individually as they rely on creating large batches for efficiency.   We have built Percolator, a system f

Introduction: nginx is a high performance smtp/pop/imap proxy that lets you do custom authorization and lookups and is very scalable. (just add nodes) Nginx by default is a reverse proxy and this is what it is doing here for pop/imap connections. It is also an excellelent reverse proxy for web servers. Advantage: You dont have to have a speacial database or ldap schema. Just an url to do auth and lookup with. A url that may be accessed by a unix or a tcp socket. Write your own auth handler - according to your own policy. For example: A user called atif tries to login with the pass testxyz. You pass this infomation to a URL such as socket:/var/tmp/xyz.sock or http://auth.corp.mailserver.net:someport/someurl The auth server replies with either a FAILURE such as Auth-Status: Invalid Login or password or with a success such as Auth-Status: OK Auth-Server: OneOfThe100Servers Auth-Port: optionalyAPort We have implemented it at our ISP and it has saves us a

Introduction: Update: Offloading ALL JS Files To Google . Now you can let Google serve all your javascript files. This article tells you how to do it (upload to Google Code Project) and why it's a big win (cheap, fast, caching, parallel downloads, save bandwidth). Don't have a CDN? Why not let Google and Yahoo be your CDN? At least for Ajax libraries. No charge. Google runs a content distribution network and loading architecture for the most popular open source JavaScript libraries , which include: jQuery, prototype, script.aculo.us, MooTools, and dojo. The idea is web pages directly include your library of choice from Google's global, fast, and highly available network. Some have found much better performance and others experienced slower performance. My guess is the performance may be slower if your data center is close to you, but far away users will be much happier. Some negatives: not all libraries are included, you'll load more than you need because all functionality is included. Yahoo

Introduction: Constructing a scalable risk analysis  solution is a fascinating architectural challenge. If you come from Financial Services you are sure to appreciate that. But even architects from other domains are bound to find the challenges fascinating, and the architectural patterns of my suggested solution highly useful in other domains. Recently I held an interesting webinar  around architecting solutions for scalable and near-real-time  risk analysis  solutions based on experience gathered with Financial Services customers. Seeing the vast interest in the webinar, I would like to share the highlights with you here. From an architectural point of view, risk analysis is a data-intensive and a compute-intensive process, which also has an elaborate orchestration logic. volumes in this domain are massive and ever-increasing, together with an ever-increasing demand to reduce response time. These trends are aggravated by  global financial regulatory reforms  set following the late-2000s
