# Joining a Network

Organizations can invite you to join their network. You can accept the invitation and be part of that network or choose to decline it.

## Accepting Organization's invite 

* Once you have received an invitation to join the organization, open the invite link and Sign up on Spdyra if you do not have an account. 
* You will be prompted with the invitation, or you can view the invite in notifications.
* You can view the organization's details and choose to accept the invite or decline.
* Once you accept the invite, you will need to enter a few details for your organization for that network.
  * **Cloud Provider:** Choose providers like AWS and Azure to host your data. You can either choose Spydra hosted or you can bring your existing cloud infrastructure (BYOC) to join the network. \
    [Create & Manage BYOC Hosting](/how-to/private-network/organizations/create-and-manage-byoc-hosting.md)
  * **Cloud Region:** This is where you want your data to be hosted on the server.
  * **Node size:** We offer 3 node sizes, Small, Medium, and Large, which come with different computational power.
  * **Number of Peer nodes**
  * **Number of orderer nodes** \[We recommend using odd-ordered nodes] 
  * **Hosting type:** Choose between shared and dedicated types. By sharing the network, other organizations can also be hosted on the same network, reducing the pricing for each node. If you go ahead with a dedicated network, no organizations will be sharing that network.

Node sizes define the computational power that comes with each node. Refer to the following table:

<table><thead><tr><th width="225">Type of nodes / Size</th><th>Small</th><th>Medium</th><th>Large</th></tr></thead><tbody><tr><td>Peer nodes</td><td>With 0.5 CPU, 1 GB RAM, 20 GB Storage</td><td>With 1 CPU, 2 GB RAM, 50 GB Storage</td><td>With 2 CPU, 4 GB RAM, 150 GB Storage</td></tr><tr><td>Orderer nodes</td><td>With 0.5 CPU, 1 GB RAM, 20 GB Storage</td><td>With 1 CPU, 1 GB RAM, 50 GB Storage</td><td>With 1 CPU, 2 GB RAM, 150 GB Storage</td></tr></tbody></table>

* **Number of Peer nodes**
* **Number of Orderer nodes**
* **Advanced Setting - Key Vault**

By default, Spydra sets up a key vault using HashiCorp Vault for every organisation part of the network. All the node related keys, certificates and credentials are stored in the vault.

Users can connect an external key vault to store secrets and certificates necessary for the Spydra platform for your organisation. Managed services like Azure Key Vault or AWS Secrets Manager can be used. Other popular vaults will be available soon.

* Users can connect managed key vault services like Azure Key Vault or AWS Key Manager to store keys and certificates while joining a network.
* To connect you own key-vault: Uncheck the 'Default' Spydra managed Hashicorp vault option in the hosting tab.
* For instructions on connecting to Azure Key Vault, please refer [Advance Settings: Key Vault Store](/how-to/private-network/networks/advance-settings-key-vault-store.md#connecting-azure-key-vault)
* For instructions on connecting to AWS Key Manager Key Vault, please refer [Advance Settings: Key Vault Store](/how-to/private-network/networks/advance-settings-key-vault-store.md#connecting-aws-key-manager)

#### Please note:

* Only the Network admin can set and update the role for an organization.
* You can update the node size from the network page if you want to change the node size. Updation of the number of nodes is not available now.&#x20;

#### Unable to join a network?

On the Spydra platform, free credits enable you to add up to two organizations to a network. From the third organization onward, you'll need a payment method added to the organisation, to join a network. Please add a card to your organization to join the network- [Adding a Card & Autopay](/billing-and-pricing/adding-a-card-and-autopay.md)

If you encounter any other issues, please contact your network administrator or [reach out to us](https://www.spydra.app/contact-us)
