Organisations that undergo digital transformation to improve its efficiency and effectiveness of its environment and cloud migration is often a high priority.
Data lakes are scalable and efficient pure-capture environment for all data storage needs. To get on with the big data driven transformation, all companies are now making a gradual move from on-premise data warehouses to cloud-based data lakes. While this migration is the need of the hour, it can be an overwhelming experience if undertaken without proper planning.Â Most of the enterprises are still in the planning phase, when it comes the cloud âbased data lakes. Moving to the cloud is not a âlift and shiftâ process especially for the companies that are considering on how to make the move to the cloud. A different architectural approach is required for the long-term journey to the cloud.
Here is a quick 5 step checklist to ensure a smooth transition from on-premise EDWs to data lakes in the cloud.
Take stock of your existing data and select a small low risk and high value segment of work to begin with, in order to avoid being overwhelmed by initial complexity
Ensure youâve not just architects and data modelling experts on the team, but also data maintenance workers, such as database administrators, security engineers and system analysts etc.
Chalk out a multiphase project plan starting with raw data landing zone creation to testing zone environment, governance plan (including GDPR compliance) et al and keep scope for contingencies arising during migration
*âLift & Shiftâ approach may work at some places, but youâll have to plan data modelling and routine setting leveraging automation to encompass the migration procedure
Begin offloading for data warehouse and you can keep high intensity relational data in the enterprise data warehouses and gradually move the rest transformational tasks to data lakes
Cloud migration checklist will assist you to ensure that you follow a strategical plan and you are ready for all the possible issues that might come up which will help you to avoid challenges and ensure a smooth journey. Most importantly, this will allow you to enjoy the benefits firstly attracted you to move to the cloud.
Migration to the cloud is a vital step for all the businesses. Nonetheless, it is a very comprehensive process. It requires the time and money and at the same time a solid cloud migration strategy. It a gradual process that takes time; it is an enormous journey that requires strong leadership and well-structured strategy. This can be achieved through step-wise process, making the transition more realistic and successful, if the organisation invest in the right technology, including a data management platform.
