Streamlining the Cloud Migration Process

Migrating to the cloud can seem intimidating without clarity on the step-by-step process. However, with meticulous planning and robust execution, the cloud deployment process can be smooth and disruption-free. 

Let’s run through the cloud migration playbook covering all key phases:

Cloud Migration Process 

#1. Discovery Phase

• Analyze infrastructure and application landscape: Assess your current IT infrastructure thoroughly, including servers, storage, network equipment, databases, applications, etc. This allows creating an inventory of all assets to be migrated.
• Identify migration objectives, constraints, dependencies: Determine business goals from migration like improved efficiency, faster delivery, etc. Identify technical and business constraints impacting migration, like budget, timelines, resource skills, etc. Also, document interdependencies between systems.
• Calculate TCO of current vs. future state: Compare the total cost of ownership models between retaining existing infrastructure vs migrating to the cloud. This includes capital, operational, and labor costs. It helps determine ROI.
• Design organizational structure, roles for cloud ops: Reorient IT team structure, roles, and responsibilities to suit the cloud operating model, vastly different from on-premise.
• Create processes for governance, security, compliance: Define policies spanning access control, resource allocation, data retention, etc., while adhering to industry regulations.

#2: Planning Phase

• Determine migration strategy: Rehost, Replatform, Refactor: Assess whether to simply lift and shift systems to the cloud (rehosting) vs. modifying architectures (replatforming) vs. deep refactoring of applications based on business goals, timelines, and costs.
• Select target deployment model:  public, private, hybrid cloud: Choose the right cloud model based on application architectures, security requirements, and availability needs.
• Evaluate cloud providers based on technology stack fit: Analyze cloud migration benefits and services offered by top cloud services companies AWS, Azure, GCP, etc., to pick the ideal platform based on compatibility with the existing tech stack.
• Define KPIs, success metrics, and milestones: Determine quantitative success metrics spanning performance, efficiencies, release cycles, etc. Useful for measuring ROI. Also, define delivery timelines.
• Construct detailed execution roadmap and timelines: Create an exhaustive cloud adoption plan covering phases, activities, dependencies, owner details, tools, etc., required for smooth migrations.

#3: Migration Phase

• Set up cloud accounts, services, storage infrastructure: Provision cloud provider accounts, create virtual networks, and set up storage repositories like S3 buckets, data lakes, etc., based on application requirements.
• Enable network connectivity between environments: Establish secure VPN tunnels between current infrastructure and cloud platform to facilitate real-time data flow during migration.
• Replicate data/backups to cloud repository: Gradually transfer application data, databases, and other storage systems to the cloud environment. This can be scheduled during maintenance windows.
• Deploy and configure cloud security controls: Install identity and access management, encryption, malware protection, and auditing tools offered by cloud providers to ensure a robust security posture.
• Migrate applications via selected method: Based on whether the rehosting, replatforming, or refactoring approach was chosen, existing applications are ported to the cloud environment.
• Continuous testing and monitoring for optimizations: Rigorously test migrated applications for performance, security, and functionality. Monitor for glitches and optimize configurations continuously.

Understanding Different Types of Cloud Migration

With multiple approaches to porting applications to the cloud, determining the ideal migration strategy is critical yet confusing. 

Should you directly lift-and-shift systems or rebuild them cloud-native? The common types of cloud migration include the following:

1. Rehosting (Lift-and-Shift Migration) 

This is the simplest and fastest way to migrate applications to the cloud. It involves lifting the entire application from on-premise infrastructure and shifting it to infrastructure-as-a-service (IaaS) on the public cloud.

• Applications are migrated as-is without any changes
• Entire technology stack moves to cloud IaaS, including app code, databases, runtimes, etc. 
• Cloud virtual machines replicate existing environment
• Substantial cost savings from shutting down data centers
• Quick time-to-market taking only weeks
• Suited for time/budget constrained migrations

2. Replatforming (Partial Refactoring)

Here, applications are selectively modernized to optimize them for cloud-scale efficiencies. The core code base is untouched, but cloud managed services are integrated.

• Incorporates cloud DBaaS, messaging, and caches to improve performance
• Adds management and monitoring capabilities via cloud-native tools
• Enables flexibility by decoupling app modules and data layers
• Improves reliability, availabilities of apps on cloud
• Fine-tunes spending by picking managed services mix
• Needs code changes so takes more effort than rehosting

3. Repurchasing (Full Refactoring)

This approach fully re-architects applications specifically for cloud delivery with cloud-native attributes.

• App is rebuilt from the ground up using microservices and serverless models
• Cloud capabilities deeply embedded in application logic
• Demands extensive code changes and testing
• Highest effort and costs but catalyzes innovation
• Delivers long-term agility, scalability, and cost benefits
• Works best for new functionality rather than migration

Choosing between Multi-Cloud vs Single-Cloud is also pivotal. While single cloud streamlines efforts, multi-cloud fuels cost arbitrage and prevents vendor lock-in.

With due diligence into time, cost, and capabilities constraints, organizations can derive the optimal cloud migration strategy personalized to their environments, priorities, and appetite.
