2. Meghna Cloud Modules

Within the framework of Meghna Cloud, we have three essential modules to empower your cloud computing journey. The 'Authorization Module' serves as the guardian of data security, ensuring that only authorized users access the platform. In the 'Dashboard Module,' you gain centralized control and real-time insights into your cloud resources, simplifying management. However, the heart of Meghna Cloud lies in our comprehensive 'Cloud Services.' This suite offers a wide range of advanced tools and resources, from scalable infrastructure to cutting-edge data processing, machine learning, and AI capabilities. Our Cloud Services rival global industry leaders, all while safeguarding your data within the borders of Bangladesh. With Meghna Cloud Services, you can embrace innovation, agility, and efficiency in pursuit of your cloud computing goals.

2.1 Authorization

The Authorization Module is the gatekeeper to your Meghna Cloud experience. It ensures that only authorized users gain access to the platform, guaranteeing the security and privacy of your data. With state-of-the-art security protocols and user management features, you can control who can interact with your cloud resources, maintaining the highest level of data protection.

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.

Step 1: Sign Up for Meghna Cloud

To ensure a successful instance launch, users should choose the designated network interface, such as "Testing-01," from the dropdown menu or opt for any previously created interface. This decision is crucial for the seamless execution of the instance.

Network Types and Key Features

Networks provide the communication channels for instances in the cloud. You can select ports instead of networks or a mix of both. In the network section user can select whether they want to launch their instance via public / private network or both. In our cloud environment, these are network types to consider:

Public Networks:

• Provider Networks: Admin-created networks tied to physical data center resources.
• External Networks: Admins set up networks for external communication with the data center.
• Floating IPs: Allow instances to be accessible from external networks.

Shared Networks:

• Project Networks: User-created, isolated networks for individual projects.
• Subnet: Defines sub-sections within a network.

Step 7: Choose a Security Group

1. Select a Security Group from the dropdown.

Note: Choose the security groups for launching the instance. Select your desired group from the dropdown menu. Security groups manage network traffic and consist of IP filter rules. Additional rules can be added in the Network | Security Groups view. Each project has specific security groups, not shareable across projects. Associate a security group before launch for full post-deployment access, otherwise, access may be limited to a VNC console.

Note: Users can see the available “Key Pairs” in the dropdown menu. For “Create” and “Import” action the specific key pair will automatically be added on the dropdown and remain selected.

1. Click on the dropdown to select any available “Key Pairs” from the list.

Generating Key Pairs

To create key pairs, you have two options:

Linux System: Generate a key pair using the ssh-keygen command, like this: ssh-keygen -t rsa -f cloud.key. This command produces a private key (cloud.key) and its corresponding public key (cloud.key.pub).

Windows System: If you're using Windows, use PuTTYGen to create private/public keys. Launch the PuTTY Key Generator, save the keys, and copy the public key from the red-highlighted box into your .ssh/authorized_keys file.

Step 9: Configuration

You can customize your instance after it has launched using a Customized Script.

1. You can either upload a script manually or type a customized script in the description box (under 16 kb).
2. You can select if you want the Disk Partition to be done either automatically or you want to don it manually. By default, it will be selected as automatic.
3. Click on the checkbox below to configure drive.

Note: Custom scripts can be attached to instances for specific actions upon launch, such as adding a public key to a user account. You can type your script directly or load it from a file if your browser supports the HTML5 File API, with a file size limit of 16 KB. Additionally, when launching an instance, choose between "Automatic" for a single partition on the resized disk or "Manual" to create multiple partitions. To write metadata to a special configuration drive, simply check the "Configuration Drive" box; the instance will access the metadata upon boot.

Step 10: Server Group

1. Choose the server group to launch the instance.

When DHCP is enabled, devices connecting to the network receive IP addresses, subnet masks, and other configuration parameters dynamically, simplifying network setup and management.

2. 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.

3. 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.

4. 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.
