Six Steps To Migrate To Cloud

What Is Cloud Migration?

Why Move To Cloud?

  • raise the speed of IT service delivery
  • reduce total cost of ownership
  • help react faster to market changes
  • undertake IT functions that don’t create competitive differentiation
  • increase competitive power
Reasons for cloud migration

Cloud Migration Types

Full and partial migration

Cloud Models

  • Zero capital costs
  • Low IT overheads
  • Great scalability
  • Lower security
  • Some limits of customization
  • Possible latency
  • Advanced customization
  • Strong security
  • Internet and private network connections
  • High costs
  • Poor outside support
  • Limited scalability
  • Super flexibility
  • High scalability
  • Better data security
  • Complex implementation
  • Compatibility issues
Three cloud types

Six Steps To Implement Cloud Migration

Step 1. Define Migration Scope

  • rehost
  • replatform
  • refactor
  • retire
  • repurchase
  • retain
  1. The Tolerate section is suitable for apps that are impractical to migrate to the cloud. The reasons can be different: economic, technical, security, etc. The best strategy for such apps is to leave them in local facilities.
  2. The Invest section covers innovative solutions that give a promising outlook for the business. Rearchitecting and replatforming are the best strategic moves for such apps.
  3. The Migrate section usually covers essential and stable apps generating a steady income. You could use the rehosting approach as a part of your cloud migration strategy.
  4. The Eliminate section implies repurchasing or retiring apps that bring low to zero value to the business.

Step 2. Set Criteria For Successful Migration

  • Average response time — how quickly the server returns the result under normal operating conditions.
  • Maximum response time — the most extended time of server response under nonstandard conditions.
  • Total uptimethe percentage ratio of the stable app work in relation to the entire work time of the system.
  • Error ratio — the percentage of requests returned with errors to the total number of requests.
  • Error types — the detected errors, warnings, and exceptions sorted by categories.
  • Network delay — time between the client request and server response.
  • Indicator of compromise — the part of potentially malicious data found in system log entries or files.
  • Network input and output — network capacity usage across involved devices.

Step 3. Pick Up Cloud Provider

  • reliable means to protect the territory and data center perimeter
  • audio and video control of internal premises and outside area
  • strict documentation of all actions and events
  • fail-safe power supply
  • reliable backup lines
  • data protection in the cloud
  • client isolation in public cloud
  • traffic and storage encryption
  • cloud cluster fault-tolerance
  • competence
  • friendliness
  • availability
  • speed

Step 4. Use Automation Tools

Step 5. Run Trial Migration

  1. Try to move the individual parts with the least load.
  2. While in the cloud, measure all the performance metrics (you can see them above in step 2). If you find delays and gaps, work to eliminate them.
  3. When you’re happy with your current state in the cloud, get ready for a full-scale migration.
