What is SaaS Cloud Migration?

SaaS cloud migration is the process of moving your software applications from an on-premises infrastructure to a cloud-based Software-as-a-Service (SaaS) platform.

This means instead of hosting and managing your software yourself, a third-party provider handles everything, delivering the software to you over the internet.  

Businesses migrate to software as a service (SaaS) for varying reasons. Normally, companies do it when they want to adjust their resources and assign other tasks to their IT teams. Here are some of the main factors that influence a migration to SaaS: 

• Costs: Businesses may look to cloud migration for cost purposes; on-premises are typically more expensive.
  Escalabilidade: Cloud services move resources based on real-time demands. 
• Acessibilidade: Companies often migrate to SaaS clouds when their employees work from places other than the office. Whereas you can only use on-premises infrastructures on-site, clouds are remote. 
• Updates: Consider migrating to a cloud service if you and your IT team need automatic updates.
• Colaboração: If you have team members across multiple locations, consider a cloud migration.

The typical cloud migration process goes like this: 

1. Lift and Shift: Also known as rehosting. Here, you move applications from on-premises to the cloud but don’t change much. 
2. Refactoring: Also known as replatforming. Here, you tweak apps slightly based on their cloud setting. 
3. Rebuild/Re-architecturing: Here, you redesign apps for the cloud. 
4. Replacing/Repurchasing: In this phase, you switch entirely over to cloud-based SaaS apps.

Things to consider when migrating from on-premises to SaaS are: 

• Segurança: Focus on encrypting your data and keeping it within the cloud. 
• Vendor Lock-In: Look at what vendors offer in significant detail before signing an agreement. 
• Integração: Your SaaS applications need to still work within your systems. 
• Customização: Consider whether you need the flexibility of on-premises software.
• Migration: Carefully plan your data transfers.

When migrating from on-premises to SaaS, you should consider each of these points:

• Goal-Setting: Think about why you want to migrate in the first place. 
• Provider: Research the different SaaS providers and think about your objectives. 
• Planning: Set realistic timelines and outline each step. 
• Segurança: Make sure that your data is secure throughout the process.
• Testing: Test your SaaS applications before completing the migration and make tweaks where needed. 
• Training: Train your team on how to use the new cloud.
• Monitoring: Look at your cloud and identify where you may need to make alterations.
