Application migration paths

We move your apps and associated data from its on-premises environment to the cloud in a lift-and-shift approach as is, without any modifications.
If your software is incompatible with the target environment, we help you decommission your legacy applications and shift to the same or similar product with a different licensing type.
When you choose to get rid of legacy applications, we assist you with its smooth decommissioning to prevent disruptions.
We carry out application migration to the cloud and make necessary optimizations to its code or architecture to ensure its proper functioning in the new environment.
We rewrite large parts of your legacy apps to adapt them to the new environment and emerging business needs and then perform application migration to the infrastructure of your choice.
If you want to pursue a hybrid cloud strategy or are unprepared to migrate applications fully, we help you figure out a suitable arrangement, migrate the selected services, and configure the app to function properly.

Application migration to the cloud: deployment models

Cloud applications migration is aimed at moving software to a cloud environment to improve its agility and overall business resilience. When opting for cloud application migration, companies can choose between four common deployment models, each with its benefits and limitations:

Public cloud

You move your app to a cloud environment shared between multiple users and managed by the vendor.
Public cloud benefits:
  • Pay-per-use pricing
  • No hardware and infrastructure maintenance
  • On-demand scalability
Public cloud limitations:
  • Vendor lock-in
  • One-size-fits-all services
  • Lack of control

Top cloud platforms for migration

Cloud providers today offer all types of deployment models, so large enterprises and SMBs alike turn to third-party companies for their cloud infrastructure and resources. AWS, Microsoft Azure, and Google Cloud top the list of leading cloud computing platforms, this is why we have been working with them for many years and recommend them for cloud deployment. Here is how we can assist with application migration to each of them:

  • 81+ availability zones
  • SaaS, PaaS, IaaS services models
  • Pay-as-you go monthly fees
  • Best fit for large-scale applications
