PROVIDING METHOD
FIELD OF THE INVENTION
The invention relates to network architectures and to associated service providing methods.
BACKGROUND OF THE INVENTION
When a user terminal makes the choice to access a specific service while taking benefit of the advantage of a cloud, and especially of a public cloud, he can do it easily nowadays.
However, if this user terminal wishes to access several and even multiple specific services, he will have to access them through multiple different clouds, and managing this interface with multiple different clouds will be cumbersome for this user terminal and will make this user terminal lose part of the benefits of accessing a service through a cloud, of getting a service through a cloud provider.
Therefore, there is for this user terminal a technical problem to solve which can be summarized as follows: how to provide a great diversity of services provided by a great diversity of providers while keeping access to this diversity of services as transparent as possible for the user terminal?
According to a prior art trying to solve this problem, some cloud providers extend their services offering while adding continuously new services, to offer more and more services always through a same cloud access. First, few or no cloud providers are able to provide for all specific services required by a user terminal, or at least by many user terminals. Second, their complementary services may not be optimized, and this is not seldom that a user terminal would like to get a given specific service from a
given cloud provider and another specific service from another cloud provider, although both cloud providers offer both specific services, because all cloud providers are not optimized for all specific services, at least from the point of view of the requiring user terminals.
SUMMARY OF THE INVENTION
The object of the present invention is to alleviate at least partly the above mentioned drawbacks.
More particularly, the invention aims at providing for a network architecture with a single managing cloud, preferably with a single unified portal, for the user terminal to access multiple cloud providers. This single unified portal is the gateway to a global cloud itself managing multiple different clouds providing multiple different services. Thereby those clouds providers are gathered within a sky (a cloud of clouds) managed by a virtualized platform, and preferably accessible through a single unified portal. In a less preferred embodiment, this global cloud itself managing multiple different clouds could be accessed by several or few different portals.
The invention proposes a cloud based on a virtualized platform itself connected to have multiple access to multiple cloud providers respectively proposing multiple services.
This object is achieved with a network architecture comprising : user terminals, a WAN public cloud including a SD-WAN control platform, cloud providers, said WAN public cloud being implemented so as, when a requesting user terminal sends a specific service request to said WAN public cloud: to select, by using said SD-WAN control platform, at least one cloud provider for providing said specific service, to manage connection between said requesting user terminal and said selected cloud provider(s) so as to enable said selected cloud provider(s) providing said specific service to said requesting user terminal.
Thereby, the proposed solution offers simultaneously high transparency toward user since user only sees a unique cloud as well as great services diversity provided to this user, because of the use of multiple cloud providers. Proposed solution offers besides an increased flexibility because of both cloud formats on the side of user terminal and on the side of services providers which may be different from each other, the managing cloud seen by user terminal then being different from the providing clouds providing services requested by user terminal.
Use of a SD-WAN (Software Defined Wide Area Network) control platform simplifies management and operation of a WAN (Wide Area Network) by decoupling networking hardware from control mechanism of this networking hardware.
This separation of networking hardware from its control mechanism allows for improving compromise between performance increasing and cost reduction, while replacing private WAN connection systems which are less robust and more expensive.

These objects could also be achieved by such WAN cloud being private or hybrid instead of being public, but to a lesser extent, since such a private or hybrid cloud could not easily encompass the same amount and diversity of cloud providers than a public cloud.
This object is also achieved, but to a lesser extent, with a network architecture comprising : user terminals, a WAN private or hybrid cloud
including a SD-WAN control platform, cloud providers, said WAN private or hybrid cloud being implemented so as, when a requesting user terminal sends a specific service request to said WAN private or hybrid cloud: to select, by using said SD-WAN control platform, at least one cloud provider for providing said specific service, to manage connection between said requesting user terminal and said selected cloud provider(s) so as to enable said selected cloud provider(s) providing said specific service to said requesting user terminal.
This object is also achieved, but to a lesser extent, with a service providing method : within a network architecture comprising: user terminals, a WAN private or hybrid cloud including a SD-WAN control platform, cloud providers, comprising, upon request of a specific service sent from one of user terminals to said WAN private or hybrid cloud: a selection step, by using said SD-WAN control platform, of at least one cloud provider for providing said specific service, a management step of a connection between said requesting user terminal and said selected cloud provider(s) so as to enable said selected cloud provider(s) providing said specific service to said requesting user terminal.

Thereby, transparency within communication is still improved.
Preferably, one or more branches, one or more Data Centers, one or more Software as a Service providers, one or more public clouds, can communicate together, via a single unified portal managed by said SD- WAN control platform.

Preferably, the service providing method also provides: a cloud hosted controller infrastructure, and/or software defined management and automation, and/or a secure hybrid connectivity with a predetermined number of Virtual Private Networks, and/or an application routing and control process.
