definition
Virtual Private Cloud (VPC) is a dynamic public cloud computing resource pool configuration, you need to use encryption protocol, tunneling protocol and other security programs, transfer data between private enterprises and cloud service providers. VPC is basically a provider of multi-tenant architecture to become a single-tenant architecture.
Virtual Private Cloud
is similar to a virtual private network (conceptually VPN )
. A VPN can be used in a public network, such as data transmission through the Internet dedicated tunnel, the tunnel can not properly encrypted input data. Additional level of security
both to encrypt data, including the network address for generating and receiving encrypted
.
Virtual Private Cloud (Virtual Private Cloud, hereinafter referred to as VPC), elastic cloud server
to build an isolated, self-configuring and managing user virtual network environment
,
enhance the security of the user's cloud resources, simplify the user's network deployment
.
VPC can be defined in the
security group, VPN, IP address range, bandwidth
and other
network characteristics
. Users can easily through VPC
manage, configure the internal network
, safe, fast network changes. At the same time, users can customize access rules between the groups within the definition of safety elastic cloud servers, strengthen security elastic cloud servers.
history
Virtual Private Cloud (Virtual Private Cloud, VPC) is present in a shared or
public cloud
in a
private cloud
(Private Cloud), that is one kind of Internet cloud (Intercloud).
Amazon Web Services published in 2009-08-26 Amazon Virtual Private Cloud, the service allows users through
IPsec
virtual private network (VPN) to connect Amazon Elastic Compute Cloud (EC2).
Google App Engine
at 2009-04-07 released
Secure Data Connector
products also support similar functionality.
Private Cloud
Private Cloud (Private cloud) is the cloud infrastructure software and hardware resources and build
a firewall
within, for the various departments within the organization or enterprise shared
data center
resources within. Cloud private cloud completely for a particular organization and operation of the infrastructure managers may be the organization itself, or it may be a third party; position within the organization may, or may in the organization externally.
Virtual Private Network
Virtual Private Network (English: Virtual Private Network, abbreviated as VPN) is a commonly used connections, private network communication method among large enterprises or community against community. Virtual private network messages via the public network architectures: (for example
Internet
to transmit)
intranet
network messages. It uses encrypted
tunneling protocol
(Tunneling Protocol) to achieve confidentiality, the sender authentication, message accuracy and other private information safe effect. This technique can be unsafe online (eg: Internet) to send reliable, secure messaging. Note that the encrypted message or not can be controlled. No encrypted virtual private network news is still in danger of being stolen.
Daily life examples to describe, like virtual private networks: a department of a company A wants to send a letter to a department B. Company B A known address and departments B, but the letter between the company and the company can not specify the name of the department. So, A asked his secretary to specify B department's letter (A password may choose whether or not to communicate with B) B Address mailed on large
envelope
in. When Company B sent to the Secretary received from Company A Company B's letter, the secretary will specify the department to put letters in the large envelope to the company's internal mail sent to B. Similarly, B will reply to A. In the same manner
In the above example, A and B are living in different companies (intranet) calculator (or related machine), sent a letter to the other party through the normal mail (public network), and then by the secretary of the other party (for example: support virtual private network router or firewall) to the company's internal correspondence (internal network) is sent to the other way himself. Note that in the virtual private network, the Internet architecture, the secretary and the recipient may be the same person. Many
operating systems
, such as
Windows
and
Linux
, etc. because of the transport protocol used, do not have the ability to be able to achieve a virtual private network connection through other internet devices.
VPN is characterized by traditional point to point topology, they do not support or connecting a broadcast domain, Microsoft Windows NetBIOS services may not fully support or work as on the local area network (LAN). Designers have developed VPN variants, such as virtual private LAN service (the VPLS) and Layer 2 Tunneling Protocol (the L2TP), in order to overcome this limitation.
