Introduction: Sean Hall with some really good  MySQL advice :  Tune those queries . Biggest bang for your buck. Enable the slow query log and watch it. Once you've found a heavy resource intensive query, optimize it! Tune what receives real-world traffic.  Employ Master-Master Replication . Immediately have a read-only slave for your application to hit as well. Use Your Memory . Set innodb_buffer_pool_size, key_buffer_size and other key options. RAID Your Disk I/O . Use RAID 10 mirroring and striping. On EC2 striping across a number of EBS volumes using the Linux md software raid. Tune Key Parameters . speeds up inserts & updates with innodb_flush_log_at_trx_commit=2; create a tablespace and underlying datafile for each table with innodb_file_per_table. Full details at the original article .

Introduction: Sean Hull with two helpful posts: 5 Things That are Toxic to Scalability : Object Relational Mappers. Create complex queries that hard to optimize and tweak. Synchronous, Serial, Coupled or Locking Processes. Locks are like stop signs, traffic circles keep the traffic flowing. Row level locking is better than table level locking. Use async replication. Use eventual consistency for clusters. One Copy of Your Database. A single database server is a choke point.   Create parallel databases and let a driver select between them. Having No Metrics. Visualize what's happening to your system using one of the many monitoring packages. Lack of Feature Flags. Be able to turn off features via a flag so when a spike hits features can be turned off to reduce load. 3 Ways to Boost Cloud Scalability : Use Auto-scaling. Spin-up new instances when a threshold is passed and back down again when traffic drops. Horizontally Scale the Database Tier. MySQL in a master

Introduction: Amazon created a whole new class of service with their Provisioned IOPS for RDS, EBS, and DynamoDB. The idea is simple. If you want more performance, you turn a dial up. If you want less, you turn a dial down. A beautifully simple model. You pay for the performance you want, which is different than their previous cloud model, where performance varied, but you paid only for what you used.  The question: Do these higher priced services really work better? Rodrigo Campos  put this question to the test (only for EBS) by running a benchmark he describes in IOMelt Provisioned IOPS EBS Benchmark Results - December 2012 . The result? Yes,   AWS Provisioned IOPS Volumes Really Deliver More Consistent and Higher Performance IO : It is clear that the provisioned IOPS EBS volumes offer a huge performance upgrade when compared to the non-optimized EBS volumes, but as data has to be spread among more underlying disks or systems, it seems that the volume is increasingly more susceptibl

4 0.11846897 829 high scalability-2010-05-20-Strategy: Scale Writes to 734 Million Records Per Day Using Time Partitioning

Introduction: In Scaling writes in MySQL  ( slides ) Philip Tellis, while working for Yahoo, describes how using time based partitions they were able to increase their write capability from 2100 inserts per second (7 million a day) to a sustained 8500 inserts per second (734 million a day). This was capacity enough to handle the load during Michael Jackson's memorial service. In summary, the secrets to scalable writes are: Bulk inserts push up insert rate Partitioning lets you insert more records Partition based on incoming data for fast inserts Partitioning is a standard approach for handling high write loads because it means data can be written to different hard disks in parallel. In this example Phillip created a separate table for each day with each table having it's own database file. Each table is partitioned on time, 12 partitions per day, 2 hours of data per partition. Huge log streams are often handled this way. Other advantages of this approach: 1) fast drop table operations 2

Introduction: This is a guest post by  Frédéric Faure  (architect at  Ysance ), you can follow him on  twitter . How do you scale an AWS (Amazon Web Services) infrastructure? This article will give you a detailed reply in two parts: the tools you can use to make the most of Amazon’s dynamic approach, and the architectural model you should adopt for a scalable infrastructure. I base my report on my experience gained in several AWS production projects in casual gaming (Facebook), e-commerce infrastructures and within the mainstream GIS (Geographic Information System). It’s true that my experience in gaming ( IsCool, The Game ) is currently the most representative in terms of scalability, due to the number of users (over 800 thousand DAU – daily active users – at peak usage and over 20 million page views every day), however my experiences in e-commerce and GIS (currently underway) provide a different view of scalability, taking into account the various problems of availability and da

3 0.58215946 986 high scalability-2011-02-10-Database Isolation Levels And Their Effects on Performance and Scalability

Introduction: Some of us are not aware of the tremendous job databases perform, particularly their efforts to maintain the Isolation aspect of ACID. For example, some people believe that transactions are only related to data manipulation and not to queries, which is an incorrect assumption. Transaction Isolation is all about queries, and the consistency and completeness of the data retrieved by queries. This is how it works: Isolation gives the querying user the feeling that he owns the database. It does not matter that hundreds or thousands of concurrent users work with the same database and the same schema (or even the same data). These other uses can generate new data, modify existing data or perform any other action. The querying user must be able to get a complete, consistent picture of the data, unaffected by other users’ actions. Let’s take the following scenario, which is based on an Orders table that has 1,000,000 rows, with a disk size of 20 GB: 8:00: UserA started a query “SELECT

Introduction: A lot of new internet TV station startups are in the wind these days and there's a question about how they can scale their broadcasts. Today's state of the art shows you can't yet mimic the reach of broadcast TV with internet tech. But as Oprah proves, you can still capture a lot of eyeballs, if you are Oprah... Oprah drew a stunning 500,000 simultaneous viewers for an Eckhart Tolle webcast. Move Networks and Limelight Networks hosted the "broadcast" where traffic peaked at 242Gbps. A variable bitrate scheme was used so depending on their connection, a viewer could have seen 150Kbps or as high as 750Kbps. Dan Rayburn thinks The big take away from this webcast is that it shows proof that the Internet is not built to handle TV like distribution and those who think that live TV shows will be broadcast on the Internet with millions and millions of people watching, it's just not going to happen. To handle more users comments suggested capping the bitrate at 300K, using P2P
