You may have persuaded the decision making body in your company to move important data and workloads to a cloud environment. You may have even found a reliable cloud vendor which can ensure a successful migration to the cloud. The infrastructure team or IT team must try to qualify and quantify the benefits of this migration.
Without this analysis, decision making may be difficult. So, before you have evaluated the progress or shown the leaders that the migration is a success, it is imperative to see whether the investment in worthwhile or not. For this reason, you need to investigate some important factors as follows:
- When you look at the key performance indicators or KPIs, uptime is non-negotiable. So, there will not be any business which is ready to move to the cloud unless its data availability is guaranteed. You can evaluate the uptime after migration is completed on a regular basis. This will help you show whether the current metrics actually meet or surpass the expectations.
- Like uptime, performance of applications is also non-negotiable. Even if you are to get multiple cloud hosting benefits, they cannot justify the loss of responsiveness of applications. So, you need to evaluate the performance post-migration and compare it with the previous baselines to prove that there has been substantial improvement.
- It is expected that when you migrate the business data to the cloud, you will enjoy significant cost savings. Cloud technologies have been designed to lower expenses and improve efficiencies. So, it is necessary to measure the savings after migration is completed. You may have shifted the workloads which were high in priority and got more usage in order to lower the costs. Alternately, you could have revamped the existing infrastructure on the basis of utilization matrix. Whatever the strategy you may have followed, it is important to document each cost-efficiency which has been possible as a result of migration. Every IT project demands assessment of both current and estimated costs and expenses which come under two categories, Opex and Capex. The IT expenses evaluation is crucial for proposing a migration to the cloud.
- Another important factor to consider is the duration of the project in question. You must find out whether this project met the deadlines that had been prefixed by the IT team and the business decision makers. In case this project could not meet the deadline, it is necessary to find out what reasons were responsible for this. It may have been a false assessment of the complex interdependencies between applications and data. So, understanding what delayed a project is imperative. This is because you have to come up with strategies to avoid a recurrence in the future. When your project has been able to meet the deadlines set, you need to document the target date and the completion date. When the migration has been large scale in nature, you need to find out which processes and teams were responsible for the success. When you know exactly what works in your favor, you can create a success template to be followed for all future migrations.
- You need to analyze the budget to see whether the migration went over the budget or was well within the budget limits. The reasons for both these conditions need to be understood. So, you should be able to identify factors which were accountable for the success or failure in relation to your budget. This will help you to prove that success can indeed be repeated and failures can be successfully avoided.
- You must also assess how the migration affected the daily operations. It is important to find out whether the business was disrupted in the course of this process, or whether the disruption was not acceptable. You need to see whether data availability and site performances were hampered to a large extent because these are vital factors when migration projects are going to be time consuming.
- Last but not the least, any successful migration must be capable of lessening burdens on the in-house IT staff. This is possible through cloud automaton templates or deploying DevOps methods or by outsourcing maintenance tasks. This means that when migration is done, the IT teams should be ideally spending far less time on daily operations. Rather, they should be able to focus on strategic activities more such as optimizing their infrastructure or delivery services. So, your IT team should document any noticeable increase in their ability to innovate and then send this report back to you.
These are some important factors which allow you to quantify a successful cloud migration. This will help future migrations and improve business agility and efficiency.
