Synology NAS: Configure Static IP Addresses, Link Aggregation

As mentioned in early article on Jumbo frame, I bought a Synology Diskstation 1513+ NAS server and really like it. The NAS server comes with very rich features that I have just explored partially. One of my favorite features is its GUI which is Web based but feels like a desktop using the Ext Javascript framework. Besides basic functionalities, it also has appstore kind of extensibility. For example, you can install cloud storage to have your own dropbox without exposing your data on public cloud. I haven’t got time to explore all these yet, but will try them later.

Configure Static IP Address on Linux VM in VMware Player

If you run VMware Player, you would have 3 networking options for virtual machines running there: Bridged, NAT, Host-Only. In the latest 5.0.1, I also found a new one: LAN Segment. This blog has a nice explanation on these three settings if you want to get more details.

In most of cases, I use NAT for networking because the virtual machine can have Internet access which allows me to install additional software as needed. By default, VMware Player uses DHCP to dynamically assign IP address while using NAT. So you cannot guarantee to get same IP address after each rebooting.

Virtual Machine Roaming in the Cloud

If you have a mobile phone and travel to other areas or countries, you can still use it to make and receive a call. Your phone number does not change. This is called roaming in the wireless telecommunications.

In the cloud environment, your virtual machine can “travel” around as well, maybe from one datacenter to another, from your enterprise to one of your service providers or the other way around, or from one service provider to another.

It’s relatively easy for a virtual machine

The Future of the Operating System in Cloud Computing

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.
