Service plan best practices

Service plans are a great tool to create standardized hosting offerings and keep subscriptions in sync with the template. However, there are situations where service plans are not the best solution, or where the service plans require special treatment.

Let’s take a look at the best practices of when and how to use service plans. Try to guess the correct solution for each scenario and read the feedback to learn more.

Question – 01/04

Scenario 1. Your customers are quite satisfied with their chosen plans, but some customers require more disk space than others. These customers regularly ask for increased disk space.

What is the best way to satisfy these requests?

Upgrade these customers to a new service plan with more disk space included.
Modify the properties of subscriptions for each customer requiring more disk space.
Create an add-on plan that adds disk space and apply it to these customers.
Add more disk space to the current service plan for these customers.

Use add-on service plans when you want to add a single service or resource to many subscriptions – for example, additional disk space, traffic, or access to a new application.

Upgrading these customers to a new service plan is also a possible solution, although not an optimal. You’ll end up with a lot of service plans that are very similar to each other.

Adding more disk space to the current service plan is not a good solution, since everyone will get more disk space, even those customers who don’t need it and did not pay for it.

Finally, modifying subscriptions is a bad idea, since you’ll have to do it a lot. Modified subscriptions will be locked, stopping their synchronization with the service plan and completely defeating the purpose.

Question – 02/04

Scenario 2. Subscribers of the “Web Hosting” service plan often request upgrades to disk space and traffic, as well as the enabling of certain hosting features. A third of the customers subscribed to the “Web Hosting” plan ask for even more advanced permissions, more disk space, and more traffic.

What is the best way to proceed here?

Modify the “Web Hosting” service plan to satisfy the demands of the top customers on this plan.
Create an add-on service plan with more disk space, more traffic, and additional permissions.
Modify these customers’ subscriptions to add permissions and increase resources.
Create two new service plans, providing upgrade tiers over the existing “Web Hosting” plan.

For each hosting offer create three tiers of plans: one for small customers, one for medium-sized customers, and one for the largest and most demanding customers. Sell them as upgrades and provide a clear upgrade path for your customers.

You can create an add-on with multiple resources and permissions in it, but this is not a good solution. Add-ons are best suited for granular upselling of additional services and resources.

Modifying the existing service plan is not a good solution either. Providing more resources for the same price is not good for business. Furthermore, not all customers on this plan will need (or can be trusted with) advanced permissions for hosting management.

Finally, modifying subscriptions is a really bad idea. You will have to do this for each existing customer and keep doing this in the future. You’ll also have to keep records of all the custom changes you have applied. It will also cause Plesk to lock modified subscriptions and stop synchronizing them with their service plan.

Question – 03/04

Scenario 3. You notice that subscribers of the plan “Basic Hosting” keep changing their web hosting settings and enabling additional scripting options that are available only in the “Advanced Hosting” service plan.

How should you solve this problem?

Create an add-on service plan that revokes the permission “Hosting settings management.”
Modify the subscriptions of customers who keep changing their hosting settings and revoke the permission “Hosting settings management.”
Revoke the “Hosting settings management” permission in the “Basic Hosting” plan and synchronize the plan with the subscriptions.

Question – 04/04

Scenario 4. One of your customers wants to deploy his Ruby application. For that, he needs SSH access to the server. However, all plans on your server have SSH access denied and you do not want to offer SSH access on all of these plans. The customer has been doing business with you for a long time, so you trust his expertise and decide to provide him with SSH access for a short period of time.

How can you help this customer?

Create an add-on service plan that enables SSH access and apply it to the customer.
Create a new service plan with SSH access and upgrade the customer to this plan.
Update his service plan and enable SSH access.
Customize the customer’s subscription to enable SSH access.

To satisfy such a specific request, it is acceptable to modify a subscription’s properties. This, of course, will lead to the subscription being locked and not synchronizing with its service plan. However, once the customer finishes deploying his application and no longer needs SSH access, you can unlock the subscription and synchronize it with its service plan, effectively revoking SSH access.

Creating a new service plan or an add-on plan for a one-time request is not an optimal solution.

Modifying the current service plan is a bad idea, since you will enable SSH access for every other customer subscribed to this service plan. This can potentially lead to security problems.

Question 13/20

Upon a customer’s request, you allocate 10GB of additional disk space using an add-on service plan. Later, the same customer asks you to allocate an additional 10GB of disk space. What is the best way to address the request?
Select one correct answer.

Create a new add-on plan with +20GB of disk space and apply this new add-on to the customer’s subscription, removing the previously applied add-on with +10GB of disk space.

Apply the same add-on service plan with +10GB of disk space to the customer’s subscription.

Question 15/20

Subscribers of a particular service plan complain that they cannot create domain aliases, despite the fact that the service plan should allow them to create up to 5 domains and 100 domain aliases.

Select one correct answer.

The subscription is now in the “Locked” state, which prevents it from synchronizing with its service plan.
There are no side effects.
The subscription is no longer associated with any service plan and has to be managed manually.

Question 17/20

The server has a scheduled daily backup task and the latest backup of the entire server content is less than a day old. Is it true that the customer can restore his database from the server-wide backup without server administrator assistance?

Question 20/20
