# Initial cloud settings

This task describes the initial steps required for setting up communication with the cloud.

In this topic:

## Initial cloud settings overview

To initially set up communication with a cloud provider, you must establish an account with the cloud provider and obtain the cloud provider credentials. You must then set up communication to your cloud provider, and define network settings for communicating with your cloud-based load generators.

Initial settings workflow

1. Create a cloud provider account

   You must first sign up and create a cloud provider account for using the cloud provider.

   For details about creating cloud provider accounts, see the documentation provided by your cloud provider.

   Note: Integration is supported with Amazon Web Services (EC2) and Microsoft Azure cloud accounts.

2. Configure communication to the cloud provider

   When communicating with your cloud provider, you can choose to communicate directly or through a proxy.

   Type | Description
   --- | ---
   Direct Communication | The following diagram illustrates direct communication to a cloud provider: The communication is initiated from the server over the organization's firewall to the cloud provider. Open the ports on the server for outgoing requests.
   Proxy Server | The following diagram illustrates communication to a cloud provider through a proxy server: The communication is initiated from the server to the defined proxy server using HTTP tunneling. The proxy server then runs over the organization's firewall and transfers outgoing requests to the cloud provider.

   For details, see Configure cloud network settings.

3. Configure communication to your cloud-based load generators

   When communicating with your cloud-based load generators, you can choose to communicate directly or through a proxy.

   Note:

   - TLS (SSL) communication is established between the Controller and the cloud-based load generators.

   - Only load generator provisioning is supported.

   Type | Description
   --- | ---
   Direct Communication | The following diagram illustrates direct communication to a cloud-based load generator: The communication is initiated from the server and the Controller over a firewall to the cloud-based load generator. Data is transmitted through TCP (Transmission Control Protocol). The load generator should allow incoming requests on LoadRunner Agent and Remote Management Agent ports, see Configure cloud network settings. The server and the Controller must allow outgoing requests.
   Proxy Server | The following diagram illustrates communication to a cloud-based load generator through a proxy server: The communication is initiated from the server and the Controller to the defined proxy server. An HTTP Tunnel is used as a means for communicating from the server and the Controller to the proxy server. The proxy server then runs over the firewall and transfers the data to the cloud-based load generator.

   For details, see Configure cloud network settings.

4. Configure security settings

   For details on additional security features related to your cloud provider, see Security group rules.

## Configure cloud network settings

Define cloud network settings for communicating with your cloud provider (define the proxy settings if your organization uses a proxy server for communicating with an outside network), and for communicating with your cloud-based load generators.

1. Prerequisites.

   To enable TLS for your cloud-based load generator, you must create a Certification Authority (CA) and a Digital Certificate and store the files on the server and the Controller. For more details on creating the certificates, see Create digital certificates.

2. In Administration, select Configuration > Cloud. In the Accounts tab, click the Cloud Network Settings button to open the Cloud Network Settings dialog box.

3. Enable communication to your cloud provider.

   1. In the Proxy section, enter the Proxy Server URL in the format `http[s]://server[:8080]`.

   2. Enter the User Name (format: `Domain\user name`) and Password of a user with connection rights to the proxy server.

   Note: Port 8182 from load generators to the server must be opened when running NV emulation for viewing NV related graphs online. If the port is closed, graphs are still available in the offline results.

4. Enable communication for a cloud-based load generator (not available for multi-tenant environments).

   Define the load generator service ports. You can use values other than the default ones.

   Port | Description
   --- | ---
   Agent Service | The port used for running Vusers on the load generator. Make sure this port is opened for incoming communication. The default port value is 54345.
   Remote Management Agent Service | The port used for Lab Management operations. Make sure this port is opened for incoming communication. The default port value is 3333.

5. Click Save to save your settings.

## Define security settings for Amazon EC2 accounts

To define security settings on the cloud provider side for Amazon EC2 cloud accounts, perform the following:

1. From your cloud provider console, create a security group. The ports defined for communicating with the cloud-based load generator must be opened.

   For details about security groups, see the documentation provided by your cloud provider.

2. Create a key pair.

3. If you plan on working with elastic IP addresses, allocate elastic IP addresses and make sure they are opened on your organization's firewall for outgoing communication.
