Now, before I go any further with this, I should say that LaaS (Linux as a Service) is really not one of the acknowledged ?aaS acronyms. Linux servers in the cloud are generally considered PaaS (platform as a service) or IaaS (infrastructure as a service) offerings depending on how much control you need to exert over their configuration (the more you have to do, the more likely they're IaaS). The distinction may not matter unless you're setting up multiple systems in the cloud that need to interract with each other. In fact, Amazon doesn't even use these terms to describe its EC2 offerings.
Amongst the top IT trends of the moment is the development of Linux Containers. Financial and technical investors, Linux software programmers and customers believe that Linux Containers will transform the way organisations manage their Linux environments from deployment to maintenance. A recent survey by Red Hat and Techvalidate says that 56% of the respondents plan to use Linux containers as vehicles for rolling out web and eCommerce over the next two years. The respondents included a number of Fortune 500 companies and public sector organisations. Any development in the world of e-Commerce is definitely worth taking a look.
Linux and open source is driven by passionate people who write best-of-breed software and then release the code to the public so anyone can use it, without any strings attached. (Well, there is one string attached and that’s licence.)
Who are these people? These heroes of the Linux world, whose work affects all of us every day. Allow me to introduce you.

We've been covering a report from search provider Algolia pointing out a potential issue in Samsung SSDs' TRIM implementation. More recently, Samsung itself reported that the bug actually resides in the Linux kernel, and that the company had submitted a patch for the problem.
Now, we have more details of the bug. Samsung has provided us with internal documents detailing the exact cause of the issue, and the subsequent solution. We're geting a bit technical here, so we'll take some liberty to simplify. When Linux's RAID implementation receives a sequence of read or write operations, it creates separate buffers in memory for each of them.
