Amazon SimpleDB: Database in the cloud somewhere

Is Amazon going to bring the typical conventional databases to their knees? Will it mean death to the conventional DB vendors? They do mean business here, quoting the S3 team:


Today, many developers correlate the word "database" with Relational Database Management Systems (RDBMS). While RDBMS offerings provide deep functionality, for many use cases, they introduce more complexity (and more cost) than is necessary. Many developers simply want to store, process, and query their data without worrying about managing schemas, maintaining indexes, tuning performance or scaling access to their data. Amazon SimpleDB removes the need to maintain a schema, while your attributes are automatically indexed to provide fast real-time lookup and querying capabilities. This flexibility minimizes the performance tuning required as the demands for your data increase.

Amazon SimpleDB eliminates administrative complexity by providing a simple set of APIs focused on the core functionality necessary to store, process, and query your data. The simplicity of this set of APIs, and the ability to access this service "in the cloud," allow you to quickly develop sophisticated applications without employing a DBA. Amazon SimpleDB allows you to easily scale your application based on your needs. You can quickly create new domains as your data grows or your request throughput increases. You no longer have to be concerned about obtaining software licenses, purchasing and maintain hardware, and managing capacity. You pay only for what you use.




Well for know you can do some simple search commands such as :

To use Amazon SimpleDB you:

  • CREATE a new domain to house your unique set of structured data.

  • GET, PUT or DELETE items in your domain, along with the attribute-value pairs that you associate with each item. Amazon SimpleDB automatically indexes data as it is added to your domain so that it can be quickly retrieved; there is no need to pre-define a schema or change a schema if new data is added later. Each item can have up to 256 attribute values. Each attribute value can range from 1 to 1,024 bytes.

  • QUERY your data set using this simple set of operators: =, !=, <, > <=, >=, STARTS-WITH, AND, OR, NOT, INTERSECTION AND UNION. Query execution time is currently limited to 5 seconds. Amazon SimpleDB is designed for real-time applications and is optimized for those use cases.
  • Pay only for the resources that you consume.


Well if the performance gets faster, then we may not be needing all those indexes and tweaks and tunings, right?

Anyways I've applied for this limited beta. Check out the news here.

Security: VMware Workstation 6 vulnerability

vulnerable software: VMware Workstation 6.0 for Windows, possible some other VMware products as well type of vulnerability: DoS, potential privilege escalation I found a vulnerability in VMware Workstation 6.0 which allows an unprivileged user in the host OS to crash the system and potentially run arbitrary code with kernel privileges. The issue is in the vmstor-60 driver, which is supposed to mount VMware images within the host OS. When sending the IOCTL code FsSetVoleInformation with subcode FsSetFileInformation with a large buffer and underreporting its size to at max 1024 bytes, it will underrun and potentially execute arbitrary code.

Splunk that!

Saw this advert on Slashdot and went on to look for it and found the tour pretty neat to look at. Check out the demo too! So why would I need it? WHY NOT? I'd say. As an organization grows , new services, new data comes by, new logs start accumulating on the servers and it becomes increasingly difficult to look at all those logs, leave alone that you'd have time to read them and who cares about analysis as the time to look for those log files already makes your day, isn't it? Well a solution like this is a cool option to have your sysadmins/operators look at ONE PLACE and thus you don't have your administrators lurking around in your physical servers and *accidentally* messing up things there. Go ahead and give it a shot by downloading it and testing it. I'll give it a shot myself! Ok so I went ahead and installed it. Do this... [root@tarrydev Software]# ./splunk-Server-1.0.1-linux-installer.bin to install and this (if you screw up) [root@tarrydev Software]# /op

Virtualization is hot and sexy!

If this does not convince you to virtualize, believe me, nothing will :-) As you will hear these gorgeous women mention VMware, Akkori, Pano Logic, Microsoft and VKernel. They forgot to mention rackspace ;-) virtualization girl video I'm convinced, aren't you? Check out their site as well!
