Posted on by Osama Mustafa in Cloud, OCI

You have the ability to establish users for Oracle Cloud Infrastructure Identity and Access Management (IAM) for user situations that are not as common.

  • Open the navigation menu and click Identity & Security. Under Identity, click Users.

Create a Bastion – OCI

Posted on by Osama Mustafa in Cloud, OCI

What is a Bastion?

It’s essential to consider the security implications before allowing direct access to cloud services and resources, particularly as the latter expands. Some individuals get around this problem by setting up a virtual machine within the virtual cloud network and linking it to all the cloud services. This cuts down on publicly accessible services while facilitating connections for developers and system administrators. This virtual machine (VM) is like a manual bastion or leap box.

Create a Bastion

  • Connect to Oracle’s cloud service. To access the main menu, choose the hamburger icon in the upper left corner.
  • On the menu select “Identity & Security > Bastion”.
  • Select the compartment and click the “Create bastion” button.
  • Enter the bastion name and select the VCN and subnet for the bastion. We need to enter a CIDR block allowlist. In this case I’ve used the subnet for my IP address from my internet service provider. Click the “Create bastion” button.
  • Click on the “Create session” button.
  • Connect

Our previously copied connection information should look something like this at this point.

ssh -i  -N -L :ip-connection:22 -p 22 ocid1.bastionsession.oc1.uk-london-1.amaa...3acq@host.bastion.uk-london-1.oci.oraclecloud.com

OCI Basics – Putting Data into Object Storage OCI

Posted on by Osama Mustafa in Cloud, OCI

The Object Storage service provides reliable, secure, and scalable object storage. Object storage is a storage architecture that stores and manages data as objects. Some typical use cases include data backup, file sharing, and storing unstructured data like logs and sensor-generated data.

Creating a Bucket

  1. Open the navigation menu and click Storage. Under Object Storage, click Buckets.A list of the buckets in the compartment you’re viewing is displayed.
  2. Select a compartment from the Compartment list on the left side of the page.A list of existing buckets is displayed.
  3. Click Create Bucket.
    • Bucket Name
    • Default Storage Tier: Select the default tier in which you want to store your data
      • Standard is the primary, default storage tier Use the Standard tier for storing frequently accessed data that requires fast and immediate access.
      • Archive is the default storage tier used for archive storage, Use the Archive tier for storing rarely accessed data that requires long retention periods. Access to data in the Archive tier is not immediate. Archived data must be restored before the data is accessible.
      • Object Events: Select Emit Object Events if you want to enable the bucket to emit events for object state changes. For more information about events.
      • Encryption: Buckets are encrypted with keys managed by Oracle by default, but you can optionally encrypt the data in this bucket using your own Vault encryption key. To use Vault for your encryption needs, select Encrypt Using Customer-Managed Keys

Uploading Files to a Bucket

To upload files to your bucket using the Console:

  1. From the Object Storage Buckets screen, click the bucket name to view its details.
  2. Click Upload.
  3. In the Object Name Prefix field, optionally specify a file name prefix for the files that you plan to upload.
  4. If the Storage Tier field displays Standard, you can optionally change the storage tier to upload objects to.

Launching Windows Instance on OCI

Posted on by Osama Mustafa in Cloud, OCI

In this post  I will show you how to launch and connect to a Windows instance.

  • Create a cloud network and subnet that enables internet access
  • Launch an instance
  • Connect to the instance
  • Add and attach a block volume

I already posted a post how to Launch Linux Instance on OCI here, in the post you will have to follow the first two steps which is creating

  • Choose a compartment for your resources.
  • Create a cloud network.

Once you are done, you can start with steps #3 which will allow you to launch a instance – windows one.

  1. Open the navigation menu and click Compute. Under Compute, click Instances.
  2. Click Create instance.
  3. In the Placement section, accept the default Availability domain.
  4. In the Image and shape section, do the following:
    • In the Image source list, select Platform images.
    • Select Windows. Then, in the OS version list, select Server 2019 Standard.
    • Review and accept the terms of use, and then click Select image.
  5. In the Shape section, click Change Shape. Then, do the following:
    • For Instance type, accept the default, Virtual machine.
    • For Shape series, select AMD, and then choose either the VM.Standard.E4.Flex shape or the VM.Standard.E3.Flex shape (it doesn’t matter which). Accept the default values for OCPUs and memory.
    • The shape defines the number of CPUs and amount of memory allocated to the instance.
  6. In the Networking section, configure the network details for the instance. Do not accept the defaults.
    • For Primary network, leave Select existing virtual cloud network selected.
    • Select the cloud network that you created. If necessary, click Change Compartment to switch to the compartment containing the cloud network that you created.
  7. In the Boot volume section, leave all the options cleared.

Your instance now is ready.

Connect to the windows instance done by using Remote desktop, enter the public ip, username which is (opc), and the password.

Cheers
