Finally, "The Cloud" Means Something
Few jargonistic terms have annoyed me as much as, "The Cloud." When the term was first coined, its meaning was ambiguous at best. For some companies, it meant shared web hosting (but with a cooler sounding name). For others it was simply, "let us host your servers in our datacenter, which we now refer to as a cloud."
Then, finally, the concept started to solidify into offering specific services or entire software applications as a commodity removed from the server infrastructure. Honestly, I think that was the intent from the beginning, but it took several years before anyone really implemented anything useful in, "the cloud."
Software as a service (SaaS) is arguably the largest implementation of the "cloud" ideology. I had never really heard of "Platform as a Service" (PaaS) before reading up on the upcoming IBM webinar here at Linux Journal. (Full disclosure: I'm sure there is a financial partnership of some sort involved with the webinar. I don't know those details, I'm writing because I found it interesting!)
In my DayJob situation, I need to deploy a Java based application for our intranet. Since we don't have a Java application server environment, the biggest chore for me is figuring out what application server, or what servlet container to implement. Then I have to configure it, maintain it, and keep it updated with both Java itself and the web server components. That's where PaaS comes in. Instead of buying a software package as a service (SaaS), PaaS allows me to deploy whatever Java applications I want onto a fully installed, maintained, and updated Java application server.
The PaaS concept piqued my interest, and perhaps it piques yours. At the very least it gives more meat to the concept of "cloud computing", which is always a good thing. Oh, and for the record? Shared web hosting was cloud computing long before it was cool, just saying.
NOTE FROM WEBMISTRESS: The webinar Shawn referred to is HERE, and it's coming up soon!
Free Webinar: Hadoop
How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
