Cloud computing has been one of the most discussed topic over the year, and the discussion is not over because what is really being discussed is the way we will access computing an storage resources in the future. Even famous French intellectuals are giving their opinion and making predictions. Future will decide on predictions's accuracy.

What is usually less discussed is the technology behind cloud-computing, though this is no secret that virtualization is playing a key role. Cloud data-centers will be loaded with virtual machines each of these machines potentially requiring in disk-space what a complete operating system (OS) requires, which can go up to many gigabytes. How much disk-space does a virtual machine image (vdi) really consum? The only good answer is: too much. Too much because the OS is part of the infrastructure as …

For many years now, Sun provides ISVs with on-line access to Solaris, MySQL, PostgreSQL, Java, Netbeans, compilers, and much more.  This service is named EZQual and is used to evaluate Sun software,  and port and test applications on the Sun platform. To satisfy the demand we must be able to host many ISVs on a single system so we decided from scratch that the service would be implemented using virtualization, just like a cloud. Also, to provide a better user experience we decided to offer a remote desktop feature that, in conjunction with the virtualiztion, really offers what is known as a virtual desktop.

So far virtualization has been based on Solaris containers. Amongst other advantages, containers are easily provisioned by cloning a first template container. This feature is useful when - like us - you provision a …

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 …

Hi,

Support for S3 BLOB storage has now been fully integrated into the PBMS engine. It works in much the same way that I mentioned in an earlier post but with some important changes so I will explain it all again here.

When using S3 BLOB storage with PBMS the BLOB reference tracking and metadata is handled the same as before in that they are stored in the BLOB record in the repository, but the actual BLOB is stored on an S3 server.

To setup S3 storage you need to add an S3 cloud reference record to the pbms.pbms_cloud table provided by PBMS. For example:

INSERT INTO pbms.pbms_cloud(ID, Server, bucket, PublicKey, PrivateKey) VALUES(16, "S3.amazonaws.com", "PBMS-Test", "abc123", "amjr15vWq");

Then you need to tell PBMS which database should use S3 cloud storage for its BLOBs. This is done by updating a couple of records in the pbms_variable table that PBMS provides for each …

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 …
