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: Flickr offers a free basic account with limited upload bandwidth and limited storage. Download bandwidth is unlimited. Upgrading to a paid Pro account for $25/year removes all upload and storage restrictions. Flickr's terms of use warn that "professional or corporate uses of Flickr are prohibited", and all external images require a link back to Flickr.

Introduction: Have a few doubts.. here are the qs 1) is there any limit on the number of databases that can be accessed simultaneously? (MySQL) 2) will it be a problem to scale in the future if there are large number of small databases(2-5 MB) each?

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

Introduction: Now you can buy more cores on EC2 without adding more machines: The High-CPU Medium Instance is billed at $0.20 (20 cents) per hour. It features 1.7 GB of memory, 5 EC2 Compute Units (2 virtual cores with 2.5 EC2 Compute Units Each), and 350 GB of instance storage, all on a 32-bit platform. The High-CPU Extra Large Instance is billed at $0.80 (80 cents) per hour. It features 7 GB of memory, 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each), and 1,690 GB of instance storage, all on a 64-bit platform. Diagonal Scaling is making a site faster by removing machines. More on this intriguing idea in Diagonal Scaling - Don't Forget to Scale Out AND Up .

Introduction: Akamai transparently mirrors content (usually media objects such as audio, graphics, animation, video) stored on customer servers. Though the domain name is the same, the IP address points to an Akamai server rather than the customer's server. In addition to image caching, Akamai provides services which accelerate dynamic and personalized content, J2EE-compliant applications, and streaming media.

Introduction: The reference configurations described in this blueprint are starting points for building Sun Customer Ready HPC Clusters configured with Sun Fire X2100 M2 and X2200 M2 servers. The configurations define how Sun Systems Group products can be configured in a typical grid rack deployment. This document describes configurations in detail using Sun Fire X2100 M2 and X2200 M2 servers with a Gigabit Ethernet data fabric, as well as configurations using Sun Fire X2200 M2 servers with a high-speed InfiniBand fabric. These configurations focus on single rack solutions, with external connections through uplink ports of the switches. These reference configurations have been architected using Sun's expertise gained in actual, real-world installations. Within certain constraints, as described in the later sections, the system can be tailored to the customer needs. Certain system components described in this document are only available through Sun's factory integration. Although the information
