Whether it is data conversion or data migration, ISVs are fast learning the ropes when it concerns time and cost savings. Even then, there are few points that ISVs need to take into account when the customers are moving to cloud leading to data migration to cloud. Here’s a quick low-down:
Where to store?
Before migration, ISVs need to select from the various options offered by Cloud Vendors regarding data storage. For instance, S3 is perfect for outsized media filed whereas RDS is the best option for web apps. One can even go for Simple DB if the data is query-able lightweight. When the storage is right, data migration becomes far easier.
Where to locate?
Data location becomes tough if the cloud vendor doesn’t give the facility to locate the data. Before choosing a cloud vendor, it’s better to check if they allow you to identify the target storage and path. The trouble can multiply if customers are firm on the facility of data location, and not providing for the same can result in the loss of customer.
How to select data?
“What to keep and what to migrate” is the major decision when migrating data to the cloud. A particular data might be of use on premise for ‘n’ number of reasons. For this particular complexity, tools need to be devised that segregate the data based on various attributes. Thereafter, these tools can extract the data that need to be migrated.
What about shared schema model tenant?
When it is shared schema model tenant, then the already used ETL tools will not assist it. ISVs will have to keep themselves ready with the solutions much before they move to shared schema multi tenant.
Which are the data loading strategies?
ISVs need to develop APIs much before to save troubles afterwards. They can choose from numerous options. Simple APIs inspect data model failures or non-compliance but there might be a need of tenant specific model extension in case of multi tenant cloud. Workflow based
APIs run predestined workflows and come up with pre-defined errors in case of deviations
How to verify migration?
Clouds do not support standard top down, bottom up equivalence or bottom up fingerprint verification approach. This makes way for custom methods that need to be developed ahead of time.
The cloud consultants at LTS manage company’s move into the cloud. Before the move, they determine the pros and cons for adopting a Cloud platform, and even advise the company on the areas of business that would benefit from the migration. Further, they give a comprehensive breakdown of the costs involved together with the technical expertise and support to make sure the transition is as seamless as possible.
