Cloud Migration Challenges

When a company moves some or all of its data center capabilities into the cloud, the process is called cloud migration. A company moves its data usually to run on cloud-based infrastructure provided by a cloud service provider. In the past few years, a large number of companies have transitioned their data to the cloud, resulting in an increased number of cloud migrations within the cloud. Companies can even migrate between different cloud providers, which is known as cloud-to-cloud migration. 

Key benefits of migrating to the cloud

There are numerous benefits of moving telecom businesses to the cloud. It is expected that, by migrating 75 to 80% of IT workloads to the cloud, operators can save up to 50% or even more on their IT costs. Here is a list of some of the noteworthy benefits of migrating to the cloud. 

  • Better scalability: As compared to on-premises infrastructure, cloud-based infrastructure can be scaled easily to support a huge volume of workload and increased users. Earlier with a traditional IT setup, companies usually had to buy and install physical servers, storage and network equipment, and software licenses to scale up their business services. However, this is not the case with cloud-based infrastructure. Businesses don’t have to buy anything extra to scale up their business services. 
  • Reduced cost: When migrating to the cloud, the maintenance and upgrades all are handled solely by the cloud providers, allowing companies to spend considerably less amount on IT operations. Instead, companies can invest and focus their resources on developing new products or improving the existing ones. 
  • Improved performance: Cloud migration also leads to improved performance and better end-user experience. This is due to the reason that various applications, as well as websites hosted in the cloud, can be scaled easily and effectively to serve more and more users. These can also run in regions near end-users, thus reducing network latency. 
  • Superior experience: Cloud-based services offer an excellent digital experience to the users. Whether it’s an employee or a customer, one can access cloud services and data from anywhere. This ultimately results in digital transformation, creating a better experience for customers while offering advanced, scalable tools to employees. 

All the above-mentioned benefits are leading to the growing customer demand for cloud-based solutions. Although there is a swift rise in the demand for cloud-based services, few companies are still facing a few challenges while making a transition from a traditional to a cloud-based infrastructure. Let’s look at some of these challenges and ways to overcome them. 

Key challenges

Here are some of the key challenges that most organizations face as they plan to transition their resources to the cloud. Have a look: 

Costly and time-consuming process: Moving to the cloud can significantly lower the costs (infrastructure, IT, administrative, and other costs), boost productivity, and streamline the entire process. However, the process of moving to the cloud can be a costly and time-consuming affair. But in the end, it’s all worth it due to the assorted benefits that come with cloud-based infrastructure. To deal with this challenge, it is advisable to devote enough time and attention to making a plan. The best way is to approach a trusted cloud vendor that can help you in evaluating the costs associated with transition and plan an agenda that is highly effective and practical as well. 

Lack of well-defined migration strategy: When it comes to cloud migration, a well-defined strategy is a must to start the process. If you are confused with the migration process, it is better to discuss it with your vendor. Build a plan that best meets your business requirements. Some of the most common cloud migration strategies are: 

  • Lift and shift (re-hosting) strategy: Lift and shift or re-hosting strategy is commonly used for low-impact workloads. It is quite fast and less disrupting as compared to other approaches. 
  • Move and improve (re-platforming) strategy: It is a strategy that provides similar benefits that are offered by the lift and shift strategy. Additionally, it also comprises various upgrades when it comes to different applications and processes. 
  • Rip and replace (re-factoring) strategy: The rip and replace strategy, also known as re-factoring or re-architecting strategy is the most complex but also potentially the most valuable strategy. This approach opens up the possibility of utilizing various features and services accessible in public clouds. Besides, it allows organizations to get rid of several problems that previous systems had, thanks to refactoring. 
  • Repurchasing strategy: There are few applications that cannot be moved to the cloud. In such a case, the users need to buy new applications that are already there on the cloud and comprise similar features. 
  • Retiring strategy: If there are some applications that you don’t require, you can simply retire them to the cloud. 
  • Cloud to cloud migration strategy: Cloud to cloud is an approach in which businesses can migrate from one cloud to another as per their business requirements. 
  • Reverse cloud migration strategy: Reverse cloud migration, also known as un-clouding or de-clouding is an approach in which businesses can migrate apps from the cloud to their on-site data center. 

These are some of the key strategies. You can choose the one that best matches your cloud migration purpose. 

Data security threat: Many businesses are concerned about the security and compliance of their data when saving and processing data in the cloud. It is vital to note that choosing the right service offers a much higher level of security as compared to on-premises installations. Moreover, the implementation of AI/ML technology helps in eliminating the chances of fraud and any suspicious behavior. 

Conclusion: 

In all, migrating from on-premises to cloud-based infrastructure is a profitable decision that you can make. Just make sure to choose a trusted vendor and work together to create a well-built strategy and execute the plan step by step to achieve success in the long run.
