2.1.1 What are the Authorization Process?​

2.1.1.1 Registration​

This guide provides instructions for setting up Meghna Cloud accounts within your organization. It’s essential to have two key pieces of information on hand for creating your Meghna Cloud account.

  1. Organization ID: Organization ID is high-level container for projects, users and groups. As such, they can be used to centrally manage all identity components. With the introduction of account domains, server, storage and other resources can now be logically grouped into multiple projects which can themselves be grouped under a master account- like container. In addition, multiple users can be managed within an account domain and assigned roles that vary for each project.

    Users of different Organization ID may be represented in different authentication back ends and even have different attributes that must be mapped to a single set of roles and privileges, that are used in the policy definitions to access the various service resources.

  2. Root Email Address: A root email is the email address under which your Meghna Cloud is created. While multiple users can be associated with the same root email, it's important to note that having two accounts with the same Organization ID and Root Email Address is not allowed.

Important: The initial option provides the choice to safeguard the volume in case of instance deletion. By default, it is set to NO, indicating that the volume won't be deleted unless you manually select YES.


  1. Select a Volume Snapshot from the dropdown.

Note: In the dropdown menu, you'll find a list of your saved volumes-snapshots. Volume snapshots are used to create consistent backups, preserving data integrity, and are especially useful for critical workloads like large databases or file systems spanning multiple Elastic Block Store (EBS) volumes.


Important: When creating an instance, you have the flexibility to select a boot source that suits your storage needs. Consider the following options:

For Ephemeral Storage (Data Lost on Instance Deletion):
  • Image: Use an image to boot the instance.
  • Instance Snapshot: Use an instance snapshot to boot the instance.

For Persistent Storage (Data Saved on Instance Deletion):
  • Image (with 'Create New Volume' checked): Utilize an image to boot the instance and create a new volume to store instance data. You can specify the volume size and whether to delete the volume when the instance is deleted.
  • Volume: Select an existing volume for instance storage. You can choose whether to delete the volume upon instance deletion. (Note: Only one instance can be launched with this option)
  • Volume Snapshot: Use a volume snapshot to boot the instance, while also creating a new volume to preserve instance data. You can choose whether to delete the volume when the instance is deleted.

Choose the option that best aligns with your storage and data preservation requirements when setting up your instance.


Step 5: Choose a Flavor

  1. Select a Flavor from the dropdown.

2.8 Network and Security​

2.8.1 Network Interface → Create Network​

Step 1: Open the Create Network Tab

  1. Sign in via Sign In - Meghna Cloud or sign up first from Registration - Meghna Cloud.
  2. Locate the left-side Navigation Bar from the dashboard; click "Network and Security" for its dropdown menu.
  3. Select "Network Interface" from the menu to be redirected to the following page.
  4. Click on Create Network located at the top right of the page.

Step 2: Input Network Information

  1. Input Network Name.
  2. Mark checkbox to Enable Admin State.

In the context of a network, "Enable Admin State" typically refers to the ability to activate or deactivate the administrative status of the network. When the admin state is enabled, the network is active and operational, allowing data transmission. Conversely, when the admin state is disabled, the network is inactive, and data transmission is halted. This feature provides administrators with control over the network's operational status for maintenance or other purposes.


  1. Mark checkbox to select if the network is Shared.

A "shared network" in the context of cloud computing or networking refers to a network that is accessible and usable by multiple users or tenants within a cloud environment. Unlike a network that is dedicated to a specific user or project, a shared network allows for the pooling of network resources, enabling multiple users or projects to utilize the same network infrastructure. This promotes resource efficiency and collaboration within a shared computing environment.


  1. Mark checkbox to Create Subnet for the network.

A "subnet," short for subnetwork, is a division of an IP network. It allows a larger network to be logically segmented into smaller, more manageable parts. Subnets are defined by a range of IP addresses and can include multiple devices or hosts. Each subnet has its own unique subset of IP addresses and typically represents a smaller section of a larger network. Subnetting is commonly used for network organization, security, and resource optimization in computer networks.


  1. Input Availability Zone Hints.

Note: Availability zones are where the DHCP agents may be scheduled. Leaving this unset is equivalent to selecting all availability zones.


  1. Input MTU for the network, adjust the quantity by typing manually or using the increment/decrement buttons.

Note: MTU stands for Maximum Transmission Unit. Minimum requirement is 68 bytes for the IPv4 subnet and 1280 bytes for the IPv6 subnet.


  1. Click Next to proceed to the next step.
  2. Click Cancel if you don’t want to create a network.

Step 3: Input Subnet Information

Creates a subnet associated with the network. You need to enter a valid "Network Address" and "Gateway IP". If you did not enter the "Gateway IP", the first value of a network will be assigned by default. If you do not want gateway, please check the "Disable Gateway" checkbox. Advanced configuration is available by clicking on the "Subnet Details" tab.


  1. Input the Subnet Name.
  2. Provide a Network Address (for example: 192.168.10.0/24).

Note:


  1. Select IP Version from the dropdown.

Note: IPv4 and IPv6 are internet protocol standards for addressing and routing data on the Internet. IPv4 uses 32-bit addresses, expressed as four sets of numbers separated by periods (e.g., 192.168.1.1). IPv6 uses 128-bit addresses, represented in hexadecimal format (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 was introduced to address the exhaustion of IPv4 addresses and provide a larger address space.


  1. Provide a Gateway IP for the network.

Note: Default Gateway IP Address is automatically set as the initial IP address within the network. For instance, in a network with the address 192.168.10.0/24, the default gateway will be 192.168.10.1. If you decide not to utilize a gateway, please check the 'Disable Gateway' option below.


  1. Click Next to proceed to the next step of network creation process.

Step 4: Input Subnet Details Information for the Network

  1. Mark the checkbox to Enable DHCP.

Enabling DHCP (Dynamic Host Configuration Protocol) allows the network to automatically assign and manage IP addresses for devices within the specified range. When DHCP is enabled, devices connecting to the network receive IP addresses, subnet masks, and other configuration parameters dynamically, simplifying network setup and management.


  1. Input Allocation Pool details.

Note: This section is for defining IP address allocation pools. Each entry should be in the format: start_ip_address, end_ip_address (e.g., 192.168.1.100,192.168.1.120), with one entry per line.


  1. Input DNS (Domain Name Servers) for the network (for example: 8.8.8.8).

DNS Name Servers translate human-readable domain names into IP addresses for computers on a network. They are vital in the DNS, ensuring seamless communication online. Servers like 8.8.8.8 (Google DNS) and 1.1.1.1 (Cloudflare DNS) offer public domain resolution services, converting domain names to IP addresses quickly and reliably. Users prefer them for speed, reliability, and enhanced security, often configuring their devices to use these servers over default ISP DNS servers.


  1. Input Host Router information.

A "Host Router" typically refers to a router that serves as the primary networking device within a local area network (LAN) or home network. It acts as a gateway, directing data traffic between devices within the network and facilitating communication with external networks, such as the internet. The host router manages the routing of data packets, assigns local IP addresses to devices, and often includes additional features like firewall capabilities and wireless connectivity. In essence, the host router plays a central role in network management and connectivity for devices within a specific environment.
