AWS Migration

AWS Migration: The Essence

AWS migration involves transferring an IT infrastructure or specific components such as databases, data warehouses, applications, and virtual desktops to the AWS environment. Mille Solutions AWS migration projects deliver benefits like cost optimization, enhanced service performance, and simplified scaling of storage and computing resources.

Duration: Approximately 5 months, depending on the project’s scope.
Migration Process: Includes defining the migration scope and strategy, planning the project, migrating data and workloads, and optimizing the AWS environment.
Cost: Migration expenses range from $5,000 for basic lift-and-shift migrations to $20,000–$100,000 for more complex migrations requiring application re-architecting. AWS infrastructure costs average $95,000. Use our online calculator for an estimate tailored to your needs.
Required Team: A project manager, cloud architect, software developer, IT security specialist, database engineer, QA engineer, and DevOps engineer.

5 Steps of AWS Migration

There are multiple factors that influence your AWS migration initiative, such as the complexity of your existing IT infrastructure, the timeline and budget you have for migration.

While every migration project is unique, Mille Solutions distills the typical steps of each AWS migration that we take in our projects.

1. Defining the scope of AWS migration

Drawing up a list of IT infrastructure elements to migrate (databases, data warehouses and data, applications, virtual desktops or a combination of them) based on the specific AWS migration goals. Analyzing the interdependencies among the infrastructure elements to migrate. Examining a data model of the migrated data: a database’s size, the number and complexity of schemas and tables.

2. Deciding on the migration strategy and model

Rehosting – moving the existing workloads to the AWS cloud without any changes. Replatforming – moving the existing applications to the AWS cloud after introducing minimal code changes and some optimization, e.g., to improve performance of the migrated app in the cloud. Repurchasing – dropping a legacy app that doesn’t suit the AWS cloud and taking on a new SaaS app. Under this model, there’s usually a need to migrate existing data to the new app. Refactoring – altering and optimizing applications, databases, etc., to make them cloud-native.

3. Planning a migration project

Developing a project plan with the outlined resources, costs and timelines to migrate to the targeted AWS environment, approaches to risk mitigation, and a roles and responsibilities matrix (e.g., RACI). Establishing KPIs for AWS migration (availability of critical services, memory usage, network latency, etc.). Creating a communication plan for the stakeholders that encompasses reporting and escalation procedures.

4. Migrating to the AWS environment

Creating an AWS production environment. Setting up DevOps tools and processes for fast delivery. Migrating workloads and data to the AWS environment. We start AWS migration only after we are sure about the quality of to-be-migrated data. We get rid of duplicated, erroneous, invalid data beforehand to optimize the time and resources needed for its migration.

5. Testing and optimizing the AWS cloud environment

esting the performance of the migrated solutions in the AWS environment. Conducting HIPAA, GDPR or other regulatory compliance assessment, penetration testing, and technical audit (to identify operational flaws) of the AWS infrastructure and the migrated workloads. Improving security (if required) and optimizing cloud performance. Setting up cloud monitoring tools, e.g., Amazon EC2 Dashboard, Amazon Cloud Watch, AWS X-Ray.
