Cloud Migration: The Guidance for Your Digital Transformation

Why companies are moving to the cloud? The pros and cons

  • Lower operational costs due to the reduced infrastructure overhead.
  • Unlimited scalability: no need to build up an infrastructure for each of your business location. Plus, you can always upgrade your storage or capacity, if needed.
  • Fast deployment. This means you can roll out software updates for all users simultaneously, no matter where they are.
  • Reliability. Cloud providers usually offer a solid disaster recovery package and guarantee the minimum possible downtime.
  • The transition itself, i.e. the total time, cost, and effort for cloud migration.
  • Data security. Sadly, cloud providers often become a subject of security breaches and data leaks that lead to millions of dollars in damage.
  • Dependance on the vendor. Be it changes in your pricing plan or global service outage, there’s nothing you can do but grin and bear (or change the cloud provider).

How to move to the cloud? Our 7-step cloud migration roadmap

1.Decide on your cloud type and service model

  • Infrastructure as a Service (IaaS)
  • Platform as a Service (PaaS)
  • Software as a Service (SaaS)
  1. Public cloud is usually owned and run by a third-party vendor (e.g. AWS, Microsoft Azure, Rackspace). The main specific is that you don’t get an exclusive right to use the resources offered by the vendor: other companies can use them as well.
  2. Unlike the public one, private cloud is used exclusively by your company. In this case, the cloud infrastructure is built and managed internally by your team.
  3. If you decide to go with the hybrid solution you can use both cloud types at the same time. For example, you can host your apps in the public cloud and store your data internally, in the private environment.

2. Allocate your resources wisely

3. Evaluate your current apps and infrastructure

4. Document the requirements and plan the milestones

5. Run a pilot project

6. Move on with the main cloud migration phases

  • Rehosting, often referred to as “lift and shift”, is the most straightforward way to move to the cloud. In this case, you simply re-host your apps in the cloud, copying your code to the new environment without any changes, step by step.
  • To replatform your apps, you have to not just migrate your code to the cloud but also update it so it meets the requirements of the new infrastructure.
  • Refactoring is a more complex approach to cloud migration, which requires a complete app rearchitecting or even rewriting certain portions of your code to tailor your apps to the cloud environment.

7. Automate the processes, monitor and improve the performance
