Installation Process for Private Cloud Environment (GCP)

Step-by-step process to launch Klera on Google cloud platform, starting with instance launch.

Klera Production System Specifications

To allow user select a particular configuration in a private cloud. The hardware requirement is as follows:-

Base Platform - 250 users/node, 5% concurrency

Base Platform with AI/ML/Python support - 250 users/node, 5% concurrency

1. In the Google Cloud console, go to the VM instances   Go to VM instances
   
   
2. Select your project and click Continue
   
   
3. Click Create instance.
   
   
4. Specify a Name for your VM. For more information, see Resource naming convention.
   
   
5. Optional: Change the Zone for this VM. Compute Engine randomizes the list of zones within each region to encourage use across multiple zones.
   
   
6. Select a Machine configuration for your VM.
   
   
7. In the Boot disk section, click Change, and then do the following:-  
   • On the Public images tab, choose the following:
     • Operating system
     • OS version
     • Boot disk type
     • Boot disk size

        

       Instance type	RAM	CPU	Disk	OS
       n2-standard- 16	64.0 GiB	16 vCPUs	SSD Persistent disk 1 TB	1.  RHEL 7.9 (For SAP with HA) 2.   Windows
       n2-standard-32	128.0 GiB	32 vCPUs	SSD Persistent disk 1.6 TB

       
       Documentation: https://cloud.google.com/compute/docs/general-purpose-machines#n2-standard

       Given N2 series, all workloads that can take advantage of the higher clock frequency are a good choice for this series. These workloads can get higher per-thread performance while benefiting from all the flexibility that the general-purpose machine family offers.

       Please note, OEL 7.6 is not available Google marketplace
       
       

   • Optional: For advanced configuration options, click Show advanced configuration.
   • To confirm your boot disk options, click Select.
     
     
8. In the Firewall section, to permit HTTP or HTTPS traffic to the VM, select Allow HTTP traffic or Allow HTTPS traffic. When you select one of these, Compute Engine adds a network tag to your VM, which associates the firewall rule with the VM. For more details on VPC, click here .
   
   Then, Compute Engine creates the corresponding ingress firewall rule that allows all incoming traffic on tcp:80 (HTTP) or tcp:443 (HTTPS).
   
   
   • Firewall rules are defined at the network level, and only apply to the network where they are created; however, the name you choose for each of them must be unique to the project.
   • Define the Protocols and ports to which the rule applies:
     • Select tcp to include the TCP protocol and destination ports. Enter all or a comma-delimited list of destination ports
     • These rules specify which incoming network traffic is delivered to your instance.
       
       

       Klera Service	Hosting Port
       Klera UI Service	18080
       Klera Content Viewer	18089
       Account Management	48444
       File Hosting Server	48446
       SSH / RDP	22 / 3389
       SMTP	465 / 587

       
       
       
9. To a public SSH key to instance metadata at the same time using the Cloud console, expand the networking, disks, security, management, sole tenancy section, and do the following:
   
   
   • Expand the Security section.
     
     • Select Add manually generated SSH keys.
     • Click Add item.
     • Add your public key in the text box. The key must be in one of the following formats:
       • Format for a key without an expiration time: KEY_VALUE USERNAME
       • Format for a key with an expiration time:
         KEY_VALUE google-ssh {"userName":"USERNAME","expireOn":"EXPIRE_TIME"}
     • Replace the following:-
       • KEY_VALUE: public SSH key value
       • USERNAME: username for the SSH key, specified when the key was created
       • EXPIRE_TIME: time the key expires, in ISO 8601 format. For example: 2021-12-04T20:12:00+0000
       
       
10. To create and start the VM, click Create.
    
    
11. A virtual machine (VM) instance requires a fixed external IP address that does not change, you can obtain a static external IP address. You can promote an ephemeral external IP address.
    
    If your instance has an ephemeral external IP address and you want to permanently assign the IP to your project, promote the ephemeral external IP address to a static external IP address.
    Promoting an ephemeral external IP address to reserved does not cause Google Cloud to drop packets sent to the instance.
     
    • • Go to External IP addresses
