According to a 2020 survey by IDG Cloud Computing, 92% of businesses use cloud computing, and the figure is expected to rise by 95% this year. This increase is from 73% in 2018 and 81% in 2019. It clearly shows that many businesses have got to know the advantages of cloud computing in recent years, and they have started their operations on a cloud platform. Some other companies have migrated from legacy platforms to cloud computing platforms. Such companies face some difficulties. Let us discuss those challenges faced on migration and the types of approaches in moving to the cloud.
Challenges faced by businesses on migration to Cloud environment
Differences in skills
Legacy platforms demand basic skills for their functioning, while the cloud environment demands different skills. A shift from a legacy environment to a cloud computing platform requires the team members to learn and possess new skills. As the company needs to maintain the legacy platform operations and cloud computing operations, the team members should work on both platforms and learn new skills.
Differences in the security model
The security model used by the legacy platforms will not be suitable for a cloud environment. Hence, the company needs to use a new security model. It may lead to a change in processes and company policies.
Challenge of resources
The migration to a cloud environment leads to scarcity of resources too. Hiring a cloud engineer who knows to work on the pre-existing software and cloud platform’s native services is an arduous task for HRs.
The resources that are the most integral part of legacy platforms may feel left out. They are unable to learn new skills very soon. They feel undervalued as they see HRs hiring cloud engineers to work for their processes. They should be engaged within the organization to avoid high attrition.
One of the most important parts of the success of a business is planning. It is one of the pillars that hold the business strong. The migration from existing software to the cloud computing platform is one of the major decisions a business takes. It requires proper planning to get the desired results. There are four types of approaches in which a company can plan for cloud migration from a legacy platform.
Single team approach
A single team approach is where the existing team members are expected to learn cloud computing and perform migrations such as re-designs and re-factors. They are also likely to support the legacy environment as and when required. The team members may find it too taxing but, they can be retained by providing incentives or a hike in their pay. This approach may work for short timeframes.
Split team approach
In this type of approach, the entire team is divided into two parts. One part of the team is assigned to work in the legacy platform, and another part is designated to learn and work on the cloud platform. The management should consider additional hires to work in both environments. The team members assigned to work in the legacy environment should be motivated by providing bonuses, incentives, and training programs not to feel left out or out of their careers.
Hybrid team approach
Here, each team within IT is addressed to work independently. Some teams work on a single team approach, and some others work on the split team approach. For example, the digital marketing department may work on the single team approach, whereas the network engineering department may work on the split team approach.
In this approach, a different organization can be asked to support and maintain your legacy platforms. This is advantageous to your company because the team can be utilized fully in the cloud platform. The partner company’s team should know the existing software and its functioning, which is important in this approach.
Cloud migration is one of the wisest decisions a business can ever make. The type of strategy for each business depends on the firm’s type and the type of process. If the proper approach is applied during migration to the cloud, it increases productivity and efficiency.
