Introduction: Scalability forces us to think differently. What worked on a small scale doesn't always work on a large scale -- and costs are no different. If 90% of our application is free of contention, and only 10% is spent on a shared resources, we will need to grow our compute resources by a factor of 100 to scale by a factor of 10! Another important thing to note is that 10x, in this case, is the limit of our ability to scale, even if more resources are added. 1. The cost of non-linearly scalable applications grows exponentially with the demand for more scale. 2. Non-linearly scalable applications have an absolute limit of scalability. According to Amdhal's Law, with 10% contention, the maximum scaling limit is 10. With 40% contention, our maximum scaling limit is 2.5 - no matter how many hardware resources we will throw at the problem. This post discuss in further details how to measure the true cost of non linearly scalable systems and suggest a model for reducing that cost signifi

Introduction: Hi, We have an application that allows the user to define a publicly available resource with an ID. The ID can then be accessed via an HTTP call, passing the ID. While we're not a picture site, thinking of a resource like a picture may help understand what is going on. We need to be able to stop access to the resource if it is accessed 'x' times in an hour, regardless of who is requesting it. We see two options - go to the database for each request to see if the # of returned in the last hour is within the limit. - keep a counter in each of the application servers and sync the counters every few minutes or # of requests to determine if we've passed the limit. The sync point would be the database. Going to the database (and updating it!) each time we get a request isn't very attractive. We also have a load balanced farm of servers, so we know 'x' is going to have to be a soft limit if we count in the app serevrs. (We know there will be a period of time between s

4 0.61956173 336 high scalability-2008-05-31-Biggest Under Reported Story: Google's BigTable Costs 10 Times Less than Amazon's SimpleDB

Introduction: Why isn't Google's aggressive new database pricing strategy getting more pub? That's what Bill Katz , instigator of the GAE Meetup and prize winning science fiction author is wondering: It's surprising that the blogosphere hasn't picked up the biggest difference in pricing: Google's datastore is less than a tenth of the price of Amazon's SimpleDB while offering a better API. If money matters to you then the burn rate under GAE could be convincingly lower. Let's compare the numbers: GAE pricing : * $0.10 - $0.12 per CPU core-hour * $0.15 - $0.18 per GB-month of storage * $0.11 - $0.13 per GB outgoing bandwidth * $0.09 - $0.11 per GB incoming bandwidth SimpleDB Pricing : * $0.14 per Amazon SimpleDB Machine Hour consumed * Structured Data Storage - $1.50 per GB-month * $0.100 per GB - all data transfer in * $0.170 per GB - first 10 TB / month data transfer out (more on the site) Clearly Google priced their services to be competitive

4 0.56757486 991 high scalability-2011-02-16-Paper: An Experimental Investigation of the Akamai Adaptive Video Streaming

Introduction: Video is hot on the Internet and people are really interested in knowing how to make it work. Dan Rayburn has a post  pointing to a fascinating paper:  An Experimental Investigation of the Akamai Adaptive Video Streaming , which talks in some detail about the protocols big players like YouTube, Skype and Akamai use to serve video over on an inherently video unfriendly medium like the Internet. For Akamai they found: Each video is encoded in five versions at different bit rates and stored in separate files. The client sends commands to the server with an average inter departure time of about 2 s, i.e. the control algorithm is executed on average each 2 seconds.  Akamai uses only the video level to adapt the video source to the available bandwidth, whereas the frame rate of the video is kept constant. When a sudden drop in the available bandwidth occurs, short interruptions of the video playback can occur due to the a large actuation delay. For a sudden increase of the avai

Introduction: A recent study showed that over 92 percent of executives from leading retailers are focusing their marketing efforts on Facebook and subsequent applications. Furthermore,  over 71 percent of users have confirmed they are more likely to make a purchase after “liking” a brand they find online.

Tomer goes through: the architectural considerations behind their solution why they chose memory over disk how they partitioned the data to gain scalability why they chose to execute code with the data using GigaSpaces Map/Reduce execution framework how they integrated with Facebook why they chose GigaSpaces over Coherence and Terracotta for in-memory caching and scale In this post I tried to summarize the main takeaway from the interview.
