The components of Cloud Computing

The components of Cloud Computing including Client, security, networking, and services.

1. The components of cloud computing - Composition client.

How to interact with the Cloud?
How to communicate with the Cloud of the client device?
Secure data on the Cloud?

- For mobile:

+ Customers using mobile phones, PDA, smartphones can access the cloud just like when sitting at their desk machine
+ However, the problem using mobile to connect to the cloud will be limited by the security and speed of access to the network. Therefore, these connections are not optimized

- For laptop, desktop:

+ These machines can still connect to a virtual server but will spend more money if you want to host on the virtual server. So we will store a piece of data on the individuals to save.
+ The personal computer is a good choice for users who need to maintain the files on your own or maintain the program doesn't exist on the Cloud.

2. The components of cloud computing - Security component.

- Data leakage:

+ The company you are having problems regarding the protection of data, because the data is stored in many places, such as laptops, Desktop.
+ The client computer uses the trends download files and store them on the hard drive, and save on a lot of laptops, so likely the leak is very large.
+ Hence the need to focus on Cloud data to avoid leaks.

- Reduce the load of work:

+ With the workload of a business, plus the protection of data is very hard.
+ So many businesses have taken up Cloud data, use the security services of the Cloud.

- Using the encryption Key:

+ When stored in the Cloud, using the encryption key to protect data.
+ The key is used as:
+ Transport keys
+ Authentication keys
+ A uthorization tokens
+ File encryption keys
+ Hardware storage keys
+ Revocation keys
+ Certificates

3. The components of cloud computing - Network Components.

- To access the Cloud, we need to have internet access environment, the exchange of information between Client and Server.
- Different companies will have different cloud requirements, so connecting to different also.

4. The composition of the cloud - Service Components

The provider of the services on the Cloud will provide the services that you need to use company.

The services provided should be providers of Cloud-level account (OpenID). Based on the information on this account, the application can determine who the user is and what they are allowed to do.

For example to use App Engine, Google requires a Google account, and Microsoft Azure requires the use of Windows Live ID account.

OpenID can be provided by:

-Google
-IBM
-Microsoft
-Yahoo!
-Apple

The service map: the map applications are increasingly common in web applications. For example, the address of the hotel, the restaurant shown on the web page or allow restaurant owners, hotel access and update their address on the map.

Online payment service:
Online payment support.

You can sign up with a service that accepts credit card, or use PayPal. With the online payment service, customers can send money directly to a person, or an organization that you want.

5. The components of cloud computing - Practical Exercises

Register your account and application deployment on Heroku.
Heroku summary
Heroku is a cloud computing environment, give you the tools to design, build and develop applications on the Cloud environment.
A number of services like Heroku:
Heroku SQL Console: provides a SQL console allows us to interact with Heroku application SQL.
Heroku Taps: used to pull/push database up Heroku
Heroku App allows managing source code on the server of Heroku. You can check out the code and commit code when developing a group project.
