Integrating cloud computing with enterprise VPNs creates a virtual private cloud (VPC) that extends and enhances management capabilities.
Strong but not enough
Every local area network (LAN) includes physical devices such as routers, switches, servers … and employees who connect to work. The usage of services and cloud resources through the Internet, in this case, shows a risk. The presence of VPC derives from the challenges of the virtual private network (VPN) with the risks when enterprises use the cloud services over the Internet.
Businesses with the cloud service will easily create virtual machines (VMs), platforms for running applications. However, as some components of the application are dropped out due to connection or attack, the enterprise will face many difficulties.
The defect of security and data accuracy in the cloud is huge. Hence, to ensure both data security as well as the independence between the network and the server, enterprises often want to manage their network rather than rent the space on the cloud service. They desire to make sure that IP addresses and employee’s resource use must base on a certain priority.
In addition, the motivation for the cloud development is that physical resources can be easily connected or removed in such space. Cloud providers must collaborate with network managers to dynamically set up servers, firewalls, routers, archives, and more.
Virtual private cloud system
A VPC combines the resources of the cloud computing such as software, service, storage, data and so forth. All of them allow users to set up and use it securely. Virtual private clouds are usually created by configuring the cloud resources and connecting them to one or more corporate sites through VPNs.
Often, people use VPNs to create secure connections for enterprise resources. VPCs apply VPNs to make secure communication channels when deploying the cloud services to enterprises and users. VPN connection points help VPC clients stay connected to other cloud users.
A VPC can have many different cloud datacenters, but it just serves one enterprise. To increase efficiency for this connection, VPNs take advantage of the Virtual Private LAN Services (VPLS). It will install to help components run easily on the cloud without having to change during the updating process. VPLS also supports to automate the processing between VMs in the cloud when working with different enterprises and clients.
Benefits of VPC
The cloud computing initially has many benefits. However, a variety of needs from enterprises requires it to broaden, particularly the virtual private networks.
For clients, the separation between the computer and network resources allows accessing to the cloud services over the VPNs as a local resource. It makes the service safer and more reliable than using them in the cloud.
On the part of service providers, it seems to be easier to manage than the discrete data centers of the past thanks to the protection of control on the client application. In the past, customers used the Internet to manipulate the software, so they sometimes dropped the connection or lost control. With the virtual private cloud, that does not happen.
