Migrating On-Premise Data to Cloud Platforms: Strategies and Challenges

Wanna become a data scientist within 3 months, and get a job? Then you need to check this out !

Many businesses in today’s world are rapidly moving their on-premise data to cloud platforms. They are doing this as cloud platforms are cost-effective, scalable, and secure in the most enhanced manner. However, do you think these organizations are not going to face any challenges while moving their data? Well, there are a lot of challenges that arise with the usage of cloud-based systems. In this article, we will explore various strategies for migrating your data to cloud-based platforms, along with the challenges they bring. It will also provide you with the necessary insights that will help you transition the data in a smooth and successful manner.

First of all, you should understand cloud migration.

What is Cloud Migration?

The cloud migration process involves moving data, applications, and other business elements from an on-site infrastructure to a cloud-based environment. In this process, you can move data from one cloud-based system to another. Now, why do people need to do cloud migration? The reasons for the same include enhanced scalability, capabilities of recovering from a disaster, and the need to reduce capital expenditures that are related to the maintenance of physical hardware.

Now, let’s talk about the strategies by which you can perform cloud migration.

Top Strategies for Cloud Migration

Here are some top-notch strategies you can follow to ensure a successful migration of your data to the cloud-based systems:

  • Planning and Assessment:

What should be the first step you should always take to ensure proper migration of data? It is by properly assessing the current infrastructure and planning the migration. This includes:

  1. Understanding the applications and data that are currently hosted on-premise.
  2. Recognizing the goals of migration, like cost-savings, scalability, security, and improved performance.
  3. Choosing the suitable service provider that will offer you the most suitable cloud-basd system for your organization.
  • Choosing a Strategy for Migration:

It is important to choose a suitable strategy for cloud migration. Here are some strategies that can help you migrate the data efficiently:

  1. Rehosting: This strategy is also known as lift and shift. It involves moving applications without making changes to them to the cloud. It is a rapid method. However, you won’t be able to utilize the features inside the cloud.
  2. Replatforming: It means making some changes to an application without restructuring its core elements. It is also known as “move and improve” or “revise” method. 
  3. Repurchasing: In this strategy, you are required to purchase a different cloud platform and move your data there.
  4. Refactoring: In this strategy, you will rewrite an application to utilize the capabilities of the cloud platform.
  5. Retire:  This strategy involves decommissioning the applications that are no longer required by the organizations.
  6. Retain: In this strategy, you will keep the applications on-premise to maintain compliance or for other reasons.
  • Migration of Data:

Data migration is the most important thing you should do while moving your data from on-premise storage to cloud-based storage. It involves:

  1. Assessment of Data: To evaluate the volume, type, and sensitivity of data which is supposed to be migrated.
  2. Data Cleanup: It involves removal of unwanted or obsolete data in order to streamline the process of data migration.
  3. Data Mapping: This process involves mapping data from source to destination to ensure a consistent and accurate migration.
  4. Choosing Appropriate Tools for Migration: In this process, you will select the suitable tools and technologies to transfer the data. There are various tools like AWS Data Migration Service, Google Cloud Data Transfer, and Azure Data Migration Services.
  • Testing:

How do you ensure that the tool you have chosen for data migration is the best one? You can check that out with the help of testing and validation. It will help you recognize any potential issues with the technology you are using. Here are the following ways in which you can test and identify the tool suitable for data transfer:

  1. Pilot testing
  2. Performance testing
  3. Security testing
  • Execution and Monitoring:

After you complete with testing, you can execute the full migration of data. You should also monitor the process continuously to ensure the migration is being executed according to your plan and address any potential issues. You can get real-time insights using tools like AWS CloudWatch, Google Cloud Operations Suite, and Azure Monitor. These tools will also issue alerts in case of any unwanted situation.

Challenges of Cloud Migration

Cloud migration has its set of challenges you need to understand. They are:

  • Data Security and Compliance:

Data security and compliance with regulatory standards is one of the primary concerns of cloud migration. Your sensitive data should be protected with the help of encryption while getting transferred and after the transfer. Furthermore, businesses should ensure that the the cloud platforms they have chosen is compliant with relevant regulations.

  • Downtime and Continuity of Business:

Migration of data and applications to the cloud software can take a lot of time, which will impact your business operations. You should avoid doing the migration during the peak hours and have a robust backup strategy, which will help you manage the side-effects of downtime.

  • Cost-Management:

Cloud migration can save you a lot of money in the long run. However, the initial costs can be quite expensive. You should have a plan to manage costs related to data transfers, training, and the potential downtime of your operations. 

  • Management of Data Integrity and Loss:

It is important for organizations to maintain the integrity of their data. There are potential risks of data loss or corruption, which can have a major impact on your business. The best way to tackle such situations is to have regular backups and validation checks to ensure data integrity. 

  • Training and Education:

Will your employees be able to run a new software without any necessary education about it? Well, it is not possible. Cloud migration requires knowledge and special skills. To get your employees trained and skilled in using such softwares, you need to partner with cloud migration service providers who are experienced and well-reputed.

  • Integration with The Current Systems:

This is another big concern for various organizations as they may require a lot of expertise and effort to ensure seamless integration with the existing systems and softwares. You will need a customized third-party integration tool that will ensure a smooth integration of cloud platforms with your systems.

  • Performance Issues:

Initially, there will be some issues with the performance of these devices, which can lead to improper configuration and delay in data transfer. You can utilize performance performance monitoring tools and cloud optimization practices to address these issues and boost the performance of your businesses.

How to Ensure Successful Cloud Migration

Here are the best ways to ensure successful migration of data into cloud-based systems in the following:

  1. Create comprehensive data for migration.
  2. Prioritizing the security of data.
  3. Ensure proper compliance of the cloud platforms with the regulations.
  4. Making the best use of automation of various processes.
  5. Conduct training on a regular basis.
  6. Monitor the cloud and data after the migration.

Final Verdict

There are various benefits of migrating on-site data to cloud-based platforms, like scalability, cost-efficiency, and improved security. However, it also has its challenges that you need to manage carefully. You can effectively tackle the complexities of cloud migration by adopting a strategic approach, using suitable tools, and having the skills and expertise to run these technologies. This will help you ensure the proper functioning of your business without any issues.
