Yikes! My Cloud host service made a change; now my services aren’t working anymore!
Let’s say you have outsourced at least some of the services you provide to your customers to a cloud hosting vendor. Your vendor will inevitably make changes to their hosting hardware and software to make improvements or to stabilize their environment. These changes might negatively affect the services you have entrusted to them.
You might also request changes from them to some of the services they’re hosting for you, to add features or to make improvements. So, the big question is, “How do you manage the changes being implemented by your cloud hosting vendor that could adversely affect your services and your customers?”
This is not an easy question to answer as this can be a complex subject. And no single answer will fit all
situations. So, let’s apply some parameters to our scenario to get started and assume the following:
If you don’t have these three things already in place, you are going to be loaded with risk. But for our scenario, we’ll accept the above assumptions. Since your cloud hosting service will be making changes that might affect the services you deliver to your customers, you must manage those changes.
With the assumptions above, you’ll need to select a supplier who is just like you! In other words, they have and use a formal, documented Change Management process based on service management best practices. They have a formal way (process) to evaluate the performance of service changes that might affect downstream services or customers. Thirdly, they will agree to respect your process designed to manage your third-party suppliers and vendors (including cloud hosting suppliers). If your cloud hosting service does not fit these criteria, you have made the wrong choice. Let’s delve into these three assumptions further.
To choose and manage your third-party suppliers, there is a process called Supplier Management. Here are the goals and objectives of your Supplier Management process (according to ITIL):
“The purpose of the Supplier Management process is to obtain value for money from suppliers and to provide seamless quality of IT service to the business by ensuring that all contracts and agreements with suppliers support the needs of the business and that all suppliers meet their contractual commitments.”
Some key objectives of Supplier Management are to:
Before choosing a third-party supplier:
Since your selected supplier has accepted the terms of the contract, they also agreed to your vision of Change Management, so injecting yourself into their Change Management process will be easier. Here are the goals and objectives of your Change Management process (according to ITIL):
“The purpose of the Change Management process is to control the lifecycle of all changes, enabling beneficial changes to be made with minimum disruption to IT services.”
We will want to manage our own changes as well as those of our supplier to:
Some key objectives of Change Management are to:
You will need to make sure your supplier also is striving to meet these same goals and objectives from their Change Management process. The best way to ensure this is happening is to be a part of their process. When a request for change is submitted to them to be assessed and evaluated by their Change Advisory Board (CAB), someone from your organization will need to be a member of their CAB so that you will be represented when the assessment takes place. You need to weigh-in on any change being proposed that could affect your services or infrastructure.
As a member of their CAB, you should receive the change requests and other supporting material (electronically) prior to the scheduled CAB meeting so you can do any necessary research before attending the meeting (electronically or otherwise). You should ensure they are using best practices for assessment and evaluation criteria before they authorize any changes.
CAB meetings should also include a Post Implementation Review (PIR) of all recent change implementations, and you should participate in those discussions, too.
A key part of successful Change Management is the coordinating/evaluating the build, test and deploy steps of the supplier’s changes utilizing the principles of the (ITIL) Change Evaluation process. If you or your supplier do not have a formal Change Evaluation process, your/their Change Management staff can still take the requisite steps to coordinate/evaluate all changes.
Coordination really means having an extra set of eyes on the steps to put a change into production. Those steps are:
Whether the person assigned to do the coordinating is someone from the Change Evaluation process or, if you don’t have a formal process, someone from the CAB, they will evaluate the results of each of the steps to ensure we have gotten acceptable outcomes that meet our criteria for success. These observations will result in Interim Evaluation Reports and a Final Evaluation Report to the CAB. These reports ensure that Change Management can expedite an effective decision about whether a service change deployment should be authorized or remediated.
Here are the goals and objectives of your Change Evaluation process (according to ITIL):
“The purpose of the Change Evaluation process is to provide a consistent and standardized means of determining the performance of a service change in the context of likely impacts on business outcomes, and on existing and proposed services and IT infrastructure. The actual performance of a change is assessed against its predicted performance. Risks and issues related to the change are identified and managed.”
Some key objectives of Change Evaluation include the following:
You can’t leave to chance that your cloud hosting service will do the right thing every time and will always follow service management best practices. So, you have to be actively involved in managing the changes they make that could impact the services you deliver to your customers. Following the guidelines discussed here will improve the outcomes you can expect from having a third-party supplier hosting services for you and making changes that might affect those services. A key success factor will be for you to become a partner with your selected supplier instead of just being their client.
