Below table shows the instances deployed by default. All the instances are named after your deployment. The system normally takes three letters of your deployment name and adds an abbreviation according to the server type. Below is the list of instances provisioned by default and all the additional instances that can also be included:
Calculating server resources
The following information explains how the auto formula works to assign your server resources:
Default: 1 CPU, 5.5 GB RAM, 50 GB storage (PDC instance)
1-7 users: 2 CPU 7.5 GB RAM
8 -15 users 4 CPU 15 GB RAM
16 – 25 users: 4 CPU 26 GB RAM
26 users and more: new USS instance will be created with 4 CPU and 13 GB RAM on both instances
Starter plan: autoscaling is pre-defined according to the formula above and the resources (RAM, CPU, Storage) are adjustable through itopia Instances module if you disable autoscaling.
Professional plan: auto-scaling can be configured according to your preferences from Cloud Manager section - Autoscaling module
Start/ Stop/ Restart instance
A great way how to manage your instances utilization is scheduling server uptime.
Regardless of the schedule, you can turn instances on and off whenever you need from itopia.
When you open CAS - Instances module, you will see the list of the instances for the selected deployment and the main options on the top:
Check the box next to instance name and proceed clicking on the corresponding icon from the menu to:
Restart the instance
Turn on the instance
Turn off the instance
Edit window will open where you can change instance parameters such as Instance type, Firewall ports, or add new disk.
You may need to change the Instance type to increase the resources (RAM, CPU). Select the instance from the drop - down list or select "Custom" if none of the instance types matches your requirements. With Custom configuration you can allocate as much RAM and CPU as needed. After the Instance type is changed, the instance needs to be rebooted in order for the changes to apply.
To add a new disk, define the disk size and disk type first and then click on the + sign on the right to add the disk to the instance.
Click the pencil icon next to the existing disk to change the storage size.
In Allow Firewall Port section you can specify ports to be open for the instance. Port should be added only in case external access to the server is needed. You can add as many ports as needed clicking on the + sign.
Firewall ports open by default:
By default the only ports open are 3389, 22 and icmp requests are allowed.
Http and https, 80/443 are only allowed if it's selected during the instances creation.
