1. A method for routing data traffic between a group of virtual datacenters implemented in a public cloud, the method comprising:
at a gateway router to which each of at least two of the virtual datacenters in the group of virtual datacenters connect, each respective virtual datacenter comprising a respective set of network management components implemented in the public cloud and a respective set of network endpoints executing in the public cloud and connected by a respective logical network that is managed by the respective network management components of respective virtual datacenter:
receiving routes advertised by the respective logical network at each of the virtual datacenters that connect to the gateway router; and
using the received routes to route data traffic, sent between the logical networks of the virtual datacenters of the group, to routers configured between the logical networks at each of the virtual datacenters and the gateway router;
wherein first traffic entering and exiting a virtual datacenter is associated with a first tier router and a second traffic between the network management components is associated with a second tier router, the first tier router and the second tier router being configured to separate the first traffic and the second traffic, the first tier router being a tier-0 router, the second tier router being a tier-1 router, a virtual datacenter being defined with two tier-1 routers connected to a tier-0 router, the tier-0 router comprising a logical router configured to handle traffic entering and exiting the virtual datacenter, the two tier-1 routers comprising a management gateway and a compute gateway segregated by the tier-0 router.
