Migrating data to the cloud can be complex. Many organizations that attempt a large-scale migration to the cloud find themselves reverting to on-premise storage because they run into a series of problems.
Cloud migration is a must in a modern world with a dispersed workforce. Organizations must respond to this need by identifying risks associated with large-scale data migration and then creating strategies to mitigate this risk. Here are some common problems organizations face and solutions that can lead to data migration success.
Choosing the Wrong Migration Strategy
There are several options for getting your workload from a data center to the public cloud. The right strategy depends on several factors. The “lift and shift” strategy is popular because it is faster and easier than other approaches. The downside is that you may lose out on some cloud-native benefits. There may also be some latency issues.
You can mitigate these challenges by understanding the cloud migration strategies available to you and then evaluating them while considering your organization’s specific needs, business requirements, workload characteristics, regulatory requirements, and risk tolerances. This will enable you to make good document migration strategy decisions from the start.
Migrating Workloads That Won’t Work Well on the Cloud
Most organizations cannot operate 100 percent of their workload in the public cloud. This includes organizations that need to take extra care when it comes to the data they store because of regulatory, privacy, or security concerns. Your organization needs to consider these factors when deciding which workloads are most appropriate for the cloud.
Additionally, your organization’s back-end architecture, transmission speed requirements, and data speed requirements may inhibit you from migrating data or applications to the cloud. To avoid this risk, you need to first assess, discover, and map your organization’s on-premise environment. Thoroughly understand how it behaves and why it behaves in a certain way. Next, evaluate how it will behave in a public cloud environment before embarking on a migration endeavor that could be ill-suited.
Failing to Identify Key Dependencies for the Migration Process
The IT environment of your organization is complex. It is an ecosystem with several components and services shared by various applications. If you fail to identify a dependency that is part of your migration plan, you may break something essential in the process.
When things don’t work and the culprit is not apparent, your organization loses valuable time and resources trying to identify the error and repair it. Some organizations have benefited from using PST file migration. This may help enterprises reduce risk and improve compliance when migrating information from on-premise to the cloud.
Migrating data to the cloud and accessing it is different than having information in an on-premise environment. There is going to be a minor increase in latency. This may or may not be acceptable, depending on the applications you are using and how you are looking at accessing your data. You need to evaluate performance in advance to mitigate issues. You want to avoid problems that could impact your organization’s ability to meet its SLAs.
You need to find a configuration that supports your organization’s performance requirements. Unfortunately, many organizations focus solely on CPU utilization. While this is an essential factor in performance, it is not the sole factor. You need to test to see how the workload will perform based on its characteristics. Compare this with your budget requirements and risk tolerances.
Your organization may be considering cloud migration because it is advertised as being more affordable. However, if you don’t plan, your organization runs the risk of being hit with higher-than-expected cloud bills. Several factors contribute to these increased costs.
Many organizations eventually migrate back to on-premise storage because they could not afford the unexpected costs. Also, if you don’t plan properly, you could experience cloud waste. This means that your company is spending more money than it needs to. The best way to mitigate this is to ensure that you are only paying for something that is giving you value in return. You need to be aware of the details. Identify unused resources and adjust your cloud usage appropriately.
Reducing Cloud Migration Risk
Migrating data to the clouds can be risky. However, you can mitigate that risk by planning, studying, and doing your due diligence before engaging in a migration.
