Abstract

Techniques are described that enable users to replicate information technology (IT) infrastructures located within the users'"'"' on-premises computing environments at a computing environment provided by a computing resources service provider. A user'"'"'s IT infrastructure can include any number of interworking components including, for example, physical servers, virtual machines (VMs), software components, as well as various types of system configurations related to networking, security, and so forth. A user may desire to replicate an on-premises IT infrastructure at a service provider network, for example, to take advantage of the increased scalability and stability of the service provider network, for reduced infrastructure and management costs, for use in on-demand verification and testing of an infrastructure, or for the ability to automatically failover servers. A service provider network provides various services that can be used to automate processes involved in replicating a user'"'"'s local IT infrastructure at a service provider network.

Claims

1. A computer-implemented method comprising:

obtaining discovery data from a customer network, the discovery data identifying at least two servers of an information technology (IT) infrastructure located in the customer network;

generating an infrastructure template based on the discovery data, the infrastructure template including server migration settings used to migrate the at least two servers from the customer network to a service provider network;

receiving a request to replicate the IT infrastructure located in the customer network at the service provider network; and

replicating the IT infrastructure at the service provider network, the replicating including, for each of the at least two servers identified by the discovery data;

obtaining replication data for the server from the customer network based on the server migration settings of the infrastructure template, and

creating a replicated instance of the server at the service provider network based on the replication data.

2. The computer-implemented method of claim 1, wherein the infrastructure template further includes system configuration settings relating to one or more of:

a subnet configuration, a security group configuration, a routing configuration; and

wherein the replicating further comprises configuring one or more system settings based on the system configuration settings.

3. The computer-implemented method of claim 1, the method further comprising:

obtaining delta replication data from the customer network for a server of the at least two servers; and

updating a replicated server instance corresponding to the server at the service provider network based on the delta replication data.

4. A computer-implemented method comprising:

receiving, over one or more networks, a request to replicate at a service provider network an information technology (IT) infrastructure located within a customer network;

obtaining an infrastructure template associated with the IT infrastructure, the infrastructure template including server migration settings used to migrate at least two servers from the customer network to the service provider network;

obtaining replication data for the at least two servers from the customer network based on the server migration settings; and

creating, based on the replication data, replicated server instances at the service provider network replicating the at least two servers.

5. The computer-implemented method of claim 4, wherein the infrastructure template further includes system configuration settings relating to one or more of:

a subnet configuration, a security group configuration, a routing configuration, and the method further comprising;

configuring one or more system settings related to the replicated server instances at the service provider network based on the system configuration settings.

6. The computer-implemented method of claim 4, further comprising:

obtaining delta replication data from the customer network for a server of the at least two servers; and

updating a replicated instance corresponding to the server at the service provider network based on the delta replication data.

7. The computer-implemented method of claim 4, wherein the IT infrastructure includes one or more of:

a virtual server, a physical server, a public subnet, a private subnet, a virtual private cloud (VPC) configuration, a routing table, a security group configuration, a software configuration.

8. The computer-implemented method of claim 4, further comprising:

obtaining discovery data from the customer network, the discovery data identifying the at least two servers of the IT infrastructure located in the customer network; and

generating the infrastructure template based on the discovery data.

9. The computer-implemented method of claim 4, wherein the server migration settings include a mapping between at least one of the at least two servers and a server instance type supported by the service provider network.
