Three simple steps- How you can migrate from your own premise data warehouse to Cloud data warehouse 

 

Migrating from your own premise data warehouse requires a considerable investment in resources and time. From replanning your data model task scheduling in a different platform to handling changes in the application’s database driver, many things should be considered before and during the migration.  

Therefore, a strategic approach is needed to compute this process. This article is intended to provide the complete procedure of migrating from a data warehouse to a Cloud in three simple steps. 

Before knowing the three simple steps, you should see why a Cloud data warehouse is more crucial for your business data. 

On-premise vs. Cloud 

Any system collecting data from a wide range of sources is a data warehouse. It is the best solution for business intelligence and analytical reporting.  

On- premise data warehouse works on onsite servers and helps in collecting, storing, and analyzing data. Hardware infrastructure management is required for this. 

The businesses may deploy their data warehouse on-premise, in the Cloud, or a combination of the two depending upon their pros and cons. However, recently, Cloud has been leaving on- premise behind due to the following reasons: 

  • Upfront cost: Hardware infrastructure demands upfront cost while working with an on-premise data warehouse not required in a Cloud data warehouse. 
  • Ongoing cost: On- premise data warehouses need upgrade and maintenance costs while Cloud data warehouse deals with the pay-as-you-go model. 
  • Performance: On-premises data architecture is an extract, transform, load (ETL) while Cloud gives leverage by working on extract, load, and transform (ETL). 
  • Flexibility: Cloud provides a design for more prominent data formats and structures than the traditional data warehouse. 
  • Scale: Scaling an extensive dataset is quickly done by Cloud, where you will struggle with a conventional data warehouse. 

How you can migrate from your own premise data to your new cloud Data warehouse 

The migration process to Cloud is gradual and not one time. So, here are the three simple steps: 

Migrate your existing data 

In this step, you have to migrate your existing data to the new data warehouse, so you don’t lose your historical data.  

Choose any good Cloud DB available in the market like Azzure, Redshift, Snowflake and copy your data there.  

Note: You can choose anyone and you can use it as your data warehouse  

As a one-time activity, you have to migrate your historical data into your new data warehouse. 

The key challenges here are:- 

  • Choosing the proper infrastructure: Copying smaller datasets and migrating in different Cloud BD is recommended. 
  • Copy all your existing data: make sure to migrate every data, so you don’t lose anything. 

Migrate ETL 

You need to set up an ongoing replication process. While migrating the data, your ETL might still be pointing to the old data warehouse. You may have to change the configuration or rewire the database to remove this. 

Migrate BI 

The last step is to migrate BI and analytics infrastructure. It would help if you again changed the configuration to point to the new data warehouse. After this step, you can analyze your new and old data in a new data warehouse five times faster. 

Final word 

A traditional data warehouse consists of a large amount of data for all the business areas. Hence, it would help if you migrated them step by step and not all at a time. If the result is a failure, take extra care while undertaking the design changes. 

This incremental approach gives you access to the old data warehouse while synchronizing at the Cloud data warehouse.

6 Steps to move the application into Cloud 

 

Companies are now shifting to cloud platforms, and it’s become a top priority globally. Many companies want to migrate applications to the Cloud but fail because they don’t know the exact strategy. And if you’re going to migrate your application into Cloud, you need to follow the six-step process we’ve covered in this article. After reading this article, you’ll successfully migrate your application into Cloud.  

So without wasting a second, let’s Begin! 

You need to follow this six steps process for the successful migration of your application to the Cloud.  

 Step 1: Cloud Vendor Assessment 

Before even taking any steps for migration, you need to clarify which platform you want to migrate your application to. Platforms like Microsoft Azure, AWS, or Google Cloud Platform are the most popular platforms for cloud hosting.  

And to select the right platform, you need to understand your application requirements. Then, based on your application needs, you need to choose cloud hosting. Also, you need to identify your application needs – Public, private, hybrid, or multi-cloud environment.  

And many other factors you need to consider for migration like Security, Compliance, and Product licenses. 

Step 2: Create a Cloud Migration Roadmap, build a team and accumulate resources. 

If you want to migrate successfully, then this step is necessary for you. You need to create a roadmap that helps you to migrate step by step. And it takes time to complete a step-by-step process of migration. It helps you to migrate easily.  

After creating a process, your main focus is to build a team that helps you accumulate resources and work on migration.  

Step 3: Build Proof of Concept of existing applications in selected cloud vendors and validate the Technology. 

You’ve already selected the platform to host and the steps you need to take for migration. But it’s much better if you find any existing similar cloud application with a similar platform. So it’s much easier for you to follow the steps and migrate successfully.  

Step 4: Migrate the Data and Move your application 

It is the most crucial step for migration because now you’re migrating your application to the Cloud. When you start following your roadmap, you may see some roadblocks. Try to be more flexible to pass the roadblocks and implement them carefully. You may need to do some modifications while implementing, so be open to doing it. First, however, you need to pay attention to your migration process.    

Step 5: Testing and Switching to Production 

Now, after implementing the migration process successfully, try to test it. Only then will you’ll get confirmation of successful migration. The next step is, switch to production. You can switch to production by two approaches. 

 

  • Do it all at once: 
  • You can wait till the entire application migrate to the Cloud, then switch Traffic to the Cloud.  
  • Do it a little bit:
  • Start sending a few customers over the Cloud. 
  • Test everything working fine. 
  • Keep sending if everything works fine. 

Step 6: Leverage the other offering of Cloud and optimize 

Now you’ve successfully migrated your application to the Cloud. And the reason behind switching to the Cloud is to optimize more and perform better. Then you can start focusing on optimization and rest other work leverage. 

Final Verdict 

If you follow these six steps processes, we are sure you can successfully migrate your application to cloud hosting. Cloud hosting is a growing technology, and you can take advantage of switching your application to the Cloud. Now it’s your turn to understand this process and switch your application to the Cloud.
