What is Cloud Migration?
The process of shifting resources such as data, services, and applications to the cloud is known as "cloud migration."
The cloud has come a long way from the early turn of the century when salesforce.com delivered applications through its website and Amazon made Amazon Web Services available outside the company. However, since the onset of the pandemic, it has become a mandate for enterprises to move to the cloud owing to the demands of remote work culture and the need to drive innovation.
A cloud migration strategy helps an organization securely move its data and applications from on-premises to the cloud. This cloud-based infrastructure provided by popular service providers such as AWS, Google Cloud, or Azure ensures that the workloads are not impacted by the migration.
Enterprises need to have a comprehensive roadmap while migrating to the cloud as there are multiple parameters that influence the process. Sonata Software, with its expertise in the field, helps you to move your business to the cloud with its unique Platformation™ driven approach, tools, and techniques. With Sonata's Azure Cloud migration and modernization services, we help you achieve your goals and objectives without losing any data.
There are a few steps to carry out the cloud migration process:
  • Planning: It is important to have clarity and certainty before initiating the cloud migration process. We help companies with assessing the current environment, cloud server requirements, application resource requirements, etc., and preparing a comprehensive roadmap for the process.
  • Choosing the Cloud Environment: Once, the initial assessment is done, we help the customers choose the correct environment for their requirements based on the model that they want to adopt. There are different environments like public cloud, hybrid cloud, private cloud, multi-cloud, etc.
  • Migration: While migrating to the cloud, we should ensure that security is our first priority, such as complying with appropriate security policies and planning for data backup and recovery.
  • Performance testing: Once the migration process is done, it is important to check the performance of applications from both a technical and business perspective in a low-risk test environment.
6R's of Cloud Migration:
  • Rehosting
    It involves shifting your workload from on-premises to the cloud environment. It suits enterprises that have no long-term strategy for harnessing cloud capabilities.
  • Replatforming
    This step involves making adjustments and optimizing the landscape for the cloud. The core architecture of applications remains the same, which helps companies build trust in the cloud.
  • Refactoring
    This step involves rebuilding the applications and data center environment from scratch. Businesses that want to leverage cloud capabilities that are not available in their existing environment should consider this option.
  • Repurchasing
    As the name suggests, this step involves moving your data center and applications to a completely new, cloud-native environment.
  • Retiring
    Retiring involves turning off some applications that are no longer required once the assessment of your cloud portfolio is done. It helps in increasing the workload efficiency.
  • Retaining
    Many organizations don't require complete cloud adoption. With this, you can migrate only what you feel makes sense for your business.
