Open source and the cloud - the quick and the dead

Savio Rodrigues has published a post arguing that cloud platforms such as Amazon Web Services and Microsoft’s Azure pose a threat to the monetization of open source by specialist vendors.

Savio makes a good case based on the recent launch of AWS’s Relational Database Service, based on MySQL, and Microsoft’s support for MySQL and Tomcat on Azure:

“When Amazon decided to offer MySQL via Amazon RDS, they did so without purchasing MySQL support from Sun. I’ve confirmed that Microsoft Azure is supporting MySQL on Azure without paying Sun for a MySQL Enterprise subscription.”

Clearly there is a threat to open source vendors from cloud-based services. Meanwhile I have previous …

Comparing Cloud Databases: SimpleDB, RDS and ScaleDB

Amazon’s SimpleDB isn’t a relational database, but it does provide elastic scalability and high-availability. Amazon’s recently announced Relational Database Services (RDS) is a relational database, but it doesn’t provide elastic scalability or high-availability. If you are deploying enterprise applications on the cloud (including Amazon Web Services), you might want to look at ScaleDB because it is a relational database and it does provide elastic scalability and high-availability.

Amazon describes SimpleDB by comparing it to a clustered database:

"A traditional, clustered relational database requires a sizable upfront capital outlay, is complex to design, and often requires extensive and repetitive database administration. Amazon SimpleDB is dramatically simpler, requiring no schema, automatically indexing your data and providing a simple API for storage and access. This approach eliminates the administrative burden of …

Three key things to know about moving MySQL into the cloud.

The question "what problems will I have when migrating to the cloud" gets asked often enough. If by cloud you mean Amazon EC2, then from a technical perspective there isn't much that changes. The biggest thing that changes is just how you pay your bill.

Having said that, there's still a few potential gotchas:

  1. There are no Virtual IP addresses. Most High Availability tools (like MMM or DRBD+Heartbeat)
    work on the principal of having a floating IP address which is used for the application to connect to the current master. With EC2, you can't do this.
  2. There's no customization of the memory. The maximum amount of memory you can have is 15GB, so some users with larger working sets may find this a limitation. If you look at the Dell online store, it costs $2094 to upgrade an R900 from 4G memory to 64G (or $4378 to upgrade to 128G) which …

As license issues swirl, a new CAOS report

There has been no shortage of lively discussion on open source software licenses with recent shifts in the top licenses, perspectives on the licenses or lack of them for networked, SaaS and cloud-based software, increased prominence of a Microsoft open source license and concern over the openness (or closedness, depending on your perspedtive) of the latest devices. Amid all of it, we’re pleased to present our latest long-form report, CAOS 12 - The Myth of Open Source …

Your opinion on EC2 and other cloud/hosting options

EC2 is nifty, but it doesn’t appear suitable for all needs, and that’s what this post is about.

For instance, a machine can just “disappear”. You can set things up to automatically start a new instance to replace it, but if you just committed a transaction it’s likely to be lost: MySQL replication is asynchronous, EBS which is slower if you commit your transactions on it, or EBS snapshots which are only periodic (you’d have to add foo on the application end). This adds complexity, and thus the question arises whether EC2 is the best solution for systems where this is a concern.

When pondering this, there are two important factors to consider: a database server needs cores, RAM and reasonably low-latency disk access, and application servers should be near their database server. This means you shouldn’t split app and db servers to different hosting/cloud providers.

We’d like to hear your thoughts on EC2 …
