BusinessWeek recently published an article “In Silicon Valley, Hardware is Hot Again.” Almost all big names started to sell hardware now, Microsoft, Google, and Apple of course. Apple’s stellar success in iPhone and iPad disrupted the conventional wisdom that software is higher in margin compared to hardware. Also, Apple’s hardware and software combined devices posts a real risk for Microsoft and Google. To be exact, the hardware in the article title should really be software bundled hardware. That is why Google and Microsoft had to get into hardware business competing directly against Apple.
Hadoop has recently gained lots of attentions from enterprises. Just think about the rapid growth of attendees in Hadoop Summit. There are many different ways to leverage Hadoop in enterprises. But in general, there are three major types of usage patterns as detailed below.
As a Framework
This is what Hadoop was initially intended to be, and continues to be one of the major approaches in the short term. It means that an enterprise needs to invest in customized application development, which normally costs more than out of shelf applications.
This past week was a busy one for Hadoop community with two Hadoop events in Silicon Valley. The first one was “what role will hadoop play in the enterprise” by Churchill Club which attracted about 300 attendees in a Palo Alto hotel. The second one was the much bigger conference Hadoop Summit in San Jose Convention Center. I will write a separate article on the second event soon.
Cloud bursting means workload moves from one cloud to another on the fly. With differentiation of public cloud and private cloud, you can have 4 different permutations: private to public, private to private, public to public, and public to private.
What people talk about the most is the case of private to public cloud. Think about the case in which
An operating system (OS) is a piece of software. It manages the computer hardware and provides common services for various applications. With the rise of cloud computing, people may wonder whether the OS is still relevant and what role it will play in the future cloud.
Key Components of OS
There are different flavors of operating systems: from real-time OS, desktop OS, all the way to a mainframe OS. The most recent OS is the Cloud OS.
In general, every OS has these common components:
- The kernel, which manages memory, processes, etc.
- Device drivers, which drive different hardware from different vendors.
- User interfaces, including command line shell and Window system.
- File system, which provides a hierarchical way to persist data.
- Security, which authenticates users and protects information.
Depending on the type of OS, you may miss something here or have something extra. For example, an embedded OS may not have a user interface and everything is controlled remotely. For the desktop OS, you may have extra commonly used applications such as a calculator, a calendar, a browser, and so on.
