Summary of the October 22, 2012 AWS Service Event in the US-East Region
We’d like to share more about the service event that occurred on Monday, October 22nd in the US- East Region. We have now completed the analysis of the events that affected AWS customers, and we want to describe what happened, our understanding of how customers were affected, and what we are doing to prevent a similar issue from occurring in the future. The Primary Event and the Impact to Amazon E
EC2 Ephemeral Disks vs EBS Volumes in RAID | three stacks of high society
EC2 Disk Overview Amazon's EC2 service is really neat, but its disk subsystem has some peculiarities that are not initially obvious. Up until very recently, root directories ('/') at EC2 were limited to 10Gb, a limit defined by the maximum size of an Amazon Machine Image (AMI), essentially a template of an EC2 instance. In order to use more disk space, Amazon provides ephemeral disks that one can
MySQL performance on EC2/EBS versus RDS
A while ago I started a series of posts showing benchmark results on Amazon EC2 servers with RAID’ed EBS volumes and MySQL, versus RDS machines. For reasons that won’t add anything to this discussion, I got sidetracked, and then time passed, and I no longer think it’s a good idea to publish those blog posts in the format I was planning. Instead, I want to write an overview of these two approaches
Death match! EBS versus SSD price, performance, and QoS
Is it a good idea to deploy your database into the cloud? It depends. I have seen it work well many times, and cause trouble at other times. In this blog post I want to examine cloud-based I/O. I/O matters a lot when a) the database’s working set is bigger than the server’s memory, or b) the workload is write-heavy. If this is the case, how expensive is it to get good performance, relative to what

New Amazon EC2 Feature: Boot from Elastic Block Store | Amazon Web Services
AWS News Blog New Amazon EC2 Feature: Boot from Elastic Block Store You can now launch Amazon EC2 instances from an AMI backed by Amazon EBS (Elastic Block Store). This new functionality enables you to launch an instance with an Amazon EBS volume that serves as the root device. This new feature brings a number of important performance and operational benefits and also enables some really powerful

MapReduce is a programming model for processing vast amounts of data. One of the reasons that it works so well is because it exploits a sweet spot of modern disk drive technology trends. In essence MapReduce works by repeatedly sorting and merging data that is streamed to and from disk at the transfer rate of the disk. Contrast this to accessing data from a relational database that operates at the
