Application Migration: the Essence

Application migration is the process of moving software from one computing environment to another. Nowadays, the most popular application migration scenario is moving apps to the cloud (public, private or hybrid) to benefit from greater flexibility and agility and easier innovation.

ScienceSoft helps enterprises and software product companies with  end-to-end cloud migration of apps of any complexity.

Time: Around 3-7 months (if without complex reengineering/re-architecting)

Key project steps: Migration prerequisites gathering and high-level planning, migration design and planning, updating application architecture and code, data migration, mock migration and failover testing, migration, testing and going live, decommissioning of an old application/unneeded application parts, continuous support.

Cost: Around $50,000 for a small application and around $200,000 - $500,000 for a medium/large application

Team: A project manager, a business analyst, a (cloud) solution architect, software and database engineers, IT security specialists, and DevOps engineers

A Sample Sequence of Application Migration Stages

Application migration stages and their timelines may differ depending on the number of applications under migration, their architecture, legacy software modifications required, migration approach, the complexity of security and compliance requirements, and more. Below are described the typical steps we at ScienceSoft take to perform application migration.

Benefits of App Migration with ScienceSoft

No long downtimes during migration

To minimize operational downtimes, we split the cloud migration process into clear, manageable parts and are always ready to roll back. Also, we employ automated tests to check the changes promptly, frequently and comprehensively.

Reduced migration and consumption costs

We devise a pragmatic cloud migration strategy to cut down on development costs. We automate resource orchestration and select cloud services to reduce cloud consumption costs.

Safe migration of legacy apps

To smoothly substitute the legacy application, we mine business rules from existing application code and documentation, investigate code dependencies and component integrations. We readily cooperate with IT departments and other employees as well as third-party vendors, customer's partners, and other people knowledgeable of the application work.

Reliability

We design failure-proof cloud apps backed with app performance management processes to enable troubleshooting activities without interrupts and suggest app recovery techniques.

Need Help in Choosing the Cloud?

ScienceSoft’s experienced cloud consultants and architects can help you choose the best-fitting cloud platform for you app migration project.

Taking into account the required human resources, the cost of cloud migration for a small application will around $50,000 and for a medium/large application will be around $200,000, in case there are no legacy platforms or languages involved and no complicated code conversion is needed. The final app migration costs will vary greatly depending on the migration project specifics and will also include the price for new infrastructure and cloud platform services costs.

Major migration cost factors

  • Scope of migration (several applications, one application, one/several app modules, etc.).
  • Complexity of applications and their dependencies.
  • The volume of data involved; cloud providers’ fees for data transfer.
  • Target app deployment option (public, private, hybrid cloud).
  • The life span of the application and its migration readiness (technology gaps).
  • App availability requirements.
  • The scope of code-level modifications required.
  • Code conversion, including manual efforts (when opting for a different programming language).
  • The extent of migration automation and the cost of migration automation software licenses.
  • Unit, system, and performance testing coverage.
  • Cloud services costs.

Major post-migration cost factors

  • Infrastructure costs, monthly/yearly application and its infrastructure support and maintenance costs.
  • IT support team training.
