Step 1 of learning cloud computing azure

When talking about the three major trends in the Internet era, it is inevitable that people think of the mobile Internet and cloud computing.

Recently I bought a few books: the beauty of mathematics, winwin on the cloud (cloud computing and future commerce), explained windowsazure cloud computing platform, and walked into the hands of cloud computing windowsazure.

To be honest, I am very lazy. I can't read books very quickly. Sometimes I can read this book. I bought it in February and I have only read about half of it now.

From winwin's book on the cloud, what does cloud computing bring to me? Many business cases have been introduced in this section, allowing me to step out of the concept of cloud computing.

There are three main cloud computing models: software as a service (SAAS), platform as a service (PAAs), and infrastructure as a service (IAAS ).

In the traditional model, traditional enterprise groups develop a project system in stages based on the IT department investment. the development cycle is really long. after Phase I Investment and Development is completed, it is found that many business needs are problematic or will not be able to meet the business expansion needs in the near future. soon, the second phase of development will be followed up immediately, and it is a long development cycle. after the three phases were completed, the system was finally launched. at first, we need to increase the cost to add hardware to meet the actual needs of the software. A large number of servers have been approved. With their own data centers, the system began to be applied. of course, there seems to be nothing wrong with this.

But will this still happen in future business?

At the end of July, when I went to the promotion class of the training institution, the lecturer said, "in the future, you don't need to worry about what the CPU/hard drive board is .. as long as you have a network cable, you can access the Internet to play the game. "" This is the benefit of cloud computing. "I don't know how long it will take for the lecturer to talk about the model. to put it bluntly, combining all software services and hardware support for management is a cloud computing platform. that is, the desktop connected to the two network cables may run on the same computer, because the virtual desktop helped us.

In the future, due to the changing business environment. only by constructing your own data centers, an enterprise requires data maintenance costs and personnel costs. But is it true that the systems you have built are fully running 24 hours a day? The answer must be no. people need to go to bed because enterprises get off work. relatively full running is not possible. Here we should talk about how to identify the real it overhead .. at this time, once there is a problem in the business, the only thing that can reduce it overhead is to cut off the staff/re-develop the goods sales terms or postpone new projects. under such fixed costs, enterprise IT costs can be controlled within a very small scope.

The visible cost control brought by the cloud computing platform can be introduced here. in cloud computing, the benefit of combining software services with hardware support is that when you use many features and how much computing costs are, you pay on demand and do not have to construct your own data centers, exaggerated: you only need to pay for the optical fiber network. your costs increase only when your business grows. I believe you are the boss and you are willing to pay more. haha'

In visible cost operation, enterprises can make effective solutions for rapid business adjustment in real time based on business needs. it is called a business agility policy. A complete set of perfect and flexible agility policies may be the true value of cloud computing. what does it mean for enterprises? Obviously, business agility can predict the development trend of new markets/quotations for enterprises, so that enterprises can quickly and reasonably reflect the situation.

Here we only talk about the concept of cloud computing. the visible cost control is also the commercial application of the system to implement scalable instances. business Benefits of business agility strategies. after all, there is always a reason to learn it.

The vs environment is vs10 SP1. Install the azure component http://www.windowsazure.com/en-us/develop/downloads /;

 

This figure shows the show cumputer emulator UI in the cloud virtual environment. Configure to start six project instances.

Start the project strength test in the project:

The number of instaces in the sub-configuration is too high and the sub-configuration is slow. We recommend that you do not set it too high.

In addition, when debugging the cloud environment, vs must have higher permissions, so vs must be right-clicked to run as an administrator.
