What is Cloud computing?

Cloud computing is a term used to refer to a model of network computing where a program or application runs on a connected server or servers rather than on a local computing device such as a PC, tablet or smartphone. Like the traditional client-server model or older mainframe computing, a user connects with a server to perform a task. The difference with cloud computing is that the computing process may run on one or many connected computers at the same time, utilizing the concept of virtualization. With virtualization, one or more physical servers can be configured and partitioned into multiple independent "virtual" servers, all functioning independently and appearing to the user to be a single physical device. Such virtual servers are in essence disassociated from their physical server, and with this added flexibility, they can be moved around and scaled up or down on the fly without affecting the end user. The computing resources have become "granular", which provides end user and operator benefits including on-demand self-service, broad access across multiple devices, resource pooling, rapid elasticity and service metering capability.

In more detail, cloud computing refers to a computing hardware machine or group of computing hardware machines commonly referred as a server or servers connected through a communication network such as the Internet, an intranet, a local area network (LAN) or wide area network (WAN). Any individual user who has permission to access the server can use the server's processing power to run an application, store data, or perform any other computing task. Therefore, instead of using a personal computer every time to run a native application, the individual can now run the application from anywhere in the world, as the server provides the processing power to the application and the server is also connected to a network via the Internet or other connection platforms to be accessed from anywhere. All this has become possible due to increased computer processing power available to humankind with decreased cost as stated in Moore's law.

Understanding SSID / BSSID


Understanding the Network Terms SSID

The terms BSSID, ESSID, and SSID are all used to describe sections of a wireless network (WLAN)—the three terms have slightly different meanings. As a wireless user you are concerned only with the broadcast SSIDs that let you connect to a wireless network. As an administrator, you also need to keep track of BSSIDs and, to a lesser degree, ESSIDs.

This topic describes:Radios can have up to 32 SSIDs

  • An SSID is the Name of a Network
  • BSSIDs Identify Access Points and Their Clients
  • An ESS Consists of BSSs



An SSID is the Name of a Network

Each BSS or ESS is identified by a service set identifier (SSID) - a 1 to 32 byte string. This is normally a human-readable string and thus commonly called the "network name". Because multiple WLANs can coexist in one airspace, each WLAN needs a unique name—this name is the service set ID (SSID) of the network. Your wireless device can see the SSIDs for all available networks—therefore, when you click a wireless icon, the SSIDs recognized by device are listed. For example, suppose your wireless list consists of three SSIDs named Student, Faculty, and Voice. This means that an administrator has created three WLAN Service profiles and, as part of each WLAN service profile, provided the SSID name Student, Faculty, or Voice. (For directions to create a WLAN Service profile, see Creating and Managing a WLAN Service Profile.)

As a WLAN user, you are concerned only with the SSIDs. You select one from the list on your laptop or other device, provide your username and a password, and use the SSID. You might not have access to all SSIDs—the authentication and access privileges are usually different for different WLANs and their associated SSIDs.


BSSIDs Identify Access Points and Their Clients

The basic service set (BSS) provides the basic building-block of an 802.11 wireless LAN. In infrastructure mode, a single access point (AP) together with all associated stations (STAs) is called a BSS; not to be confused with the coverage of an access point, known as the basic service area (BSA) Each Access Point Has Its Own BSS

Each BSS is uniquely identified by a basic service set identification (BSSID). For a BSS operating in infrastructure mode, the BSSID is the MAC address of the wireless access point(WAP) generated by combining the 24 bit Organization Unique Identifier (the manufacturer's identity) and the manufacturer's assigned 24-bit identifier for the radio chipset in the WAP. The BSSID is the formal name of the BSS and is always associated with only one BSS. The SSID is the informal (human) name of the BSS (just like a Windows Workgroup name). A BSS is functionally a contention domain as a local or workgroup network is functionally a broadcast domain.

Packets bound for devices within the WLAN need to go to the correct destination. The SSID keeps the packets within the correct WLAN, even when overlapping WLANs are present. However, there are usually multiple access points within each WLAN, and there has to be a way to identify those access points and their associated clients. This identifier is called a basic service set identifier (BSSID) and is included in all wireless packets.

High availability - 5 Nine's !

High availability is a system design approach and associated service implementation that ensures a prearranged level of operational performance will be met during a contractual measurement period.
Users want their systems, for example hospitals, production computers, and the electrical grid to be ready to serve them at all times. Availability refers to the ability of the user community to obtain a service or good, access the system, whether to submit new work, update or alter existing work, or collect the results of previous work. If a user cannot access the system, it is - from the users point of view - unavailable.
Generally, the term downtime is used to refer to periods when a system is unavailable.

Firefox OS

iOS and Android are great, but they each have their own rules and policies that certainly inhibit the creative efforts of developers. Mozilla has since decided to build a new mobile operating system from scratch, one that will focus on true openness, freedom and user choice.

It’s Firefox OS.

Firefox OS is built on Gonk, Gecko and Gaia software layers – for the rest of us, it means it is built on open source, and it carries web technologies such as HTML5 and CSS3.

Parallella – Supercomputer in $99?


Making parallel computing easy to use has been described as "a problem as hard as any that computer science has faced". With such a big challenge ahead, we need to make sure that every programmer has access to cheap and open parallel hardware and development tools. Inspired by great hardware communities like Raspberry Pi and Arduino, we see a critical need for a truly open, high-performance computing platform that will close the knowledge gap in parallel programing. The goal of the Parallella project is to democratize access to parallel computing. If we can pull this off, who knows what kind of breakthrough applications could arise?  Maybe some of them will even change the world in some small but positive way.
