The world we live in produces huge amount of data continuously every day. This can lead to the data resource storage of the data center. Cloud computing adds capabilities dynamically without investing new infrastructure and increases the computing capacity . Cloud computing offers many benefits such as lower cost, rapid provisioning, fast deployment, rapid re-constitution of services, etc. The application software and database has been moved to the large data centers. Unfortunately, the management of services and data is not reliable. At the meanwhile, the target of cloud computing is to provide better utilization of software and data using virtualization technology . The unique attribute poses a lot of security risks in the cloud environment.

 

In order to enhance the security and save the resource of the cloud platform, in this paper, we present the essentials of Security Management of the cloud computing. The management contains a distributed authentication method and device based on the cloud platform. The management is based on the Embedded Cloud Branch Server which has multiple cloud server as the node branch. The Embedded Cloud Branch Server is connected with the central server through the network.

 

2. The Characteristic of Cloud Computing Platform

 

The cloud computing platform refers to hardware and software which in the data centers and the applications transmitted as services through the Internet . The cloud computing platform has been referred to as SaaS (Software as a Service), IaaS (Infrastructure as a Service) and PaaS (Platform as a Service) as shown in Figure 1.

 

The cloud computing is the combination of utility computing and SaaS. The public cloud refer to the cloud is made obtainable to the general public . The service being sold is called utility computing. The private cloud refers to the internal data center of a business and cannot be available to the general public. The individuals can be providers or users of utility computing and SaaS.

 

There are three new fields in cloud computing from pricing point and hardware provisioning of views.

 

1) The ability to pay for use of computing resources and release them on a short-term basis as needed.

 

2) The ability to get infinite computing resources available quickly enough to start load surges.

 

3) The ability to let company to start small and increase hardware resource when needed.

 

The cloud computing platform uses SaaS, PaaS angulad IaaS as the transmission models to delivery different types of services to the end users. The IaaS is the base of the cloud services and PaaS and SaaS build on it. The service model places a varied level of security necessity in the cloud surroundings.

 

A recent survey by Cloud Security Alliance (CSA) & IEEE indicates that enterprises across sectors are eager to adopt cloud computing but that security are needed both to accelerate cloud adoption on a wide scale and to respond to regulatory drivers  .

 

SaaS is a software arrangement model where application can be hosted remotely by the service provider or the application and made obtainable to the client through the internet.

 

IaaS transforms the method developer arrange their applications. IaaS abstracts the hardware below it and permit user to spend infrastructure like a services .

 

PaaS is the layer which is live above IaaS on the abstract and stacks away everything upper to the middleware and OS. This provides a combine set of developers circumstance which the developers could develop their applications without mention what is going on below the services.

 

In this paper, we introduce a Cloud platform which structure is the integration of SaaS, IaaS and PaaS. In today’s cloud computing environment, IaaS, is mainstream, not only Amazon EC2 but also Linode and Joyent both have a place. With the emerge of Google App Engine, sales force force.com and Microsoft Windows azure, the

PAAS platform begin to play an important role in the cloud platforms  . The Micro Cloud has high integration rate which can bring economy to developers and can solve challenges such as general and support to the application, we think the Micro Cloud can make benefits for the developer of cloud platform.
