What is Azure Service Platform?
Azure platform consists of Windows Azure, which is an Operating System to provide on demand computing, storage and management of cloud applications. In short, Windows Azure is an Operating System for the cloud computing platform designed for utility computing. It provides facilities to write, host or manage applications & store data on demand. The service layer consists of different services like: Live Service, .Net Service, SQL Service etc. which provides building blocks within the platform for the developers.
What is Cloud Computing?
Cloud computing is a dynamic style of computing in which virtualized resources are provided as a service over the internet. The users of cloud computing need not to worry about the capital expenditure and maintenance cost of hardware and software resources. They have to pay only what they are using. This can be of two types. User can either pay the provider based on the resources consumed during the time period or a time based subscription.
The Cloud Computing services are delivered through data centers & servers with different steps of reliable virtualization technologies. These are accessible from anywhere over the world with only an internet connection as it appears as a single point of access over the net.
The main characteristics of Cloud computing is:
- Add or Remove capacity on demand
- Pay for what you use as you go
- Reduce cost by implementing Automation
There are three different types of cloud computing.
- Public computing
- Private computing
- Hybrid computing
Public cloud computing is a type of computing where the providers shares the resources to the consumers dynamically via web services over the internet and bills on consumption basis.
Private cloud computing is a type of computing where the resources are shared in a private network.
Hybrid cloud computing consists of multiple public & private clouds.
Cloud computing architecture is defined as Infrastructure as a Service, Software as a Service and Platform as a Service. Infrastructure as a Service provides all the required hardware resources on terms of consumptions. User has to pay the bill based on the unit consumed during the period. So there is no need to purchase high cost servers, data center spaces or network devices. In Software as a Service providers gives an application by hosting them on their own servers to the user on demand. It actually delivers a single piece of application to multiple consumers at a time. Platform as a service delivers computing platform & solution as a service. So there is no need to buy & maintain any hardware & software for building & deploying web applications. It offers design, development, testing, deployment & hosting application throughout it's complete life cycle over the internet.
Cloud Computing is a platform which enables hosting of applications in a virtual environment over the internet. It supplies all the necessary hardware, software & storage capacity in terms of high end servers & data centers. So, there is no need to purchase or maintain those resources locally. Hence, it reduces the cost of purchasing hardware or storage space. The amount of storage space which required by the end user, has to pay only that much of amount and whenever require he can increase or decrease the amount of space to be paid. Due to its automation, no one has to worry about keeping the software's updated with all the security patches. For its flexibility over the internet, one can work from any location & can access their data from wherever they are rather than sitting on their own work-desk.
Bing – Microsoft’s new Search Engine
Microsoft launched their new search engine named Bing (Kumo) on 28th May in Europe which went fully online on 3rd June. This search engine was designed to help people not only to quickly find anything over the internet but also to plan a trip or make a purchase decision. Using "Bing" the end user can find any information they need on their daily basis to accomplish their tasks. Bing categories results in different category, based on which the user can find relevant results more accurately.

What is Google Wave?
Google Wave is a project announced by Google on 28th May 2009 at the Google I/O conference is expected to release later in 2009. This will be a next generation email subsystem designed to merge email, instant messaging, social networking & wiki featuring strong spelling/grammar checking & automated translation between nearly about 40 different languages.
The term "Waves" described by Google as "equal parts conversation and document", means any authorized participant can reply anywhere in the conversation, they can edit or can add more participants during the conversation process. All the participants will be notified of changes or replies in all the waves they are actively participating & all the modifications will be seen at real time, letter by letter. Not only this, multiple participants may edit a single wave simultaneously in the same context.
This ability of Google Wave will let user to create collaborative documents modified in different location with full modification history, which can be searched by an user to view/modify any changes just like wikis.
More information about this is available in Google Wave Site.
