What Does A Cloud Migration Service Look Like?
A cloud migration service is a professional service that helps businesses move their data and applications from their on-premises infrastructure to a cloud-based environment. The service typically includes a thorough assessment of the business’s current infrastructure, identification of which data and applications are suitable for migration, planning and implementation of the migration process, and ongoing support to ensure the smooth functioning of the cloud environment. A cloud migration service sometimes also includes training to help the business’s staff get up to speed on the new cloud-based environment. The ultimate goal of a cloud migration service is to help businesses achieve the benefits of cloud computing, such as improved scalability, cost savings, and flexibility.
Let’s explore step by step processes of cloud migration service planning and implementation:
The most crucial aspect of a cloud migration initiative is planning. This stage centers on program management arrangement, analysis of the portfolio, and designing the cloud architecture and operating model.
- Program management setup: During the planning phase, the program management team is responsible for overseeing various aspects, such as strategy development, program governance, and benefits realization. The program management team’s duties include ensuring strong leadership, implementing change management, aligning program strategy, maintaining strict project execution standards, and enforcing decision-making governance.
- Portfolio analysis: The analysis of the application portfolio is essential for a cloud migration program as it provides an accurate representation of the applications that are in scope. This analysis includes information on application dependencies, which helps in planning the sequence of application migration and strengthens the business case for cloud migration.
- Cloud foundation and operating model layout: A critical component of the cloud migration program is the establishment of a cloud foundation and operating model layout. The Cloud foundation includes Landing Zones, which are standardized sets of secured cloud infrastructure with built-in policies, standards, guidelines, and centrally managed services. Establishing a robust foundation through Landing Zones is crucial for creating a scalable and sustainable enterprise AWS cloud model. As cloud computing becomes the paradigm for delivering business, technology operating models must evolve to add more cloud-centric capabilities. The cloud operating model provides a framework for combining the core elements in a more agile, productive, and valuable way.
In the assess phase of a cloud migration program, applications are analyzed in detail to determine their future disposition. The cloud architecture and operating model provide a solid foundation for migrations.
- Macro-analysis: Macro-analysis is conducted to analyze the applications using a cloud readiness and assessment framework based on business value, IT efficiency, and cloud suitability. This analysis ensures a clear migration roadmap and identifies enterprise-wide concerns related to security, networking, technical, operational, organizational, regulatory, and financial aspects.
- Microanalysis: Once the macro-analysis is complete, the program moves on to microanalysis, which involves a deeper understanding of the current state architecture and the definition of cloud architecture based on patterns identified during macro-analysis. The microanalysis concludes with the preparation of a detailed migration plan and effort estimates.
- Cloud foundation and operating model design: The design of the cloud foundation and operating model should adhere to enterprise security and networking policies. The account and VPC structure needs to be designed based on cost allocation, resource management and ownership, and security and compliance isolation. The core elements of the cloud operating model are people, process, and technology, which should evolve to achieve the cloud operating model goals, thereby increasing business and operations value. People skills and experience are geared towards becoming more cross-functional, processes are realigned around services, and tools and technologies are selected for the effective implementation and automation of processes.
Setting Up Cloud Landing Zone
Building a landing zone in cloud migration service involves setting up a pre-configured environment that provides a foundation for secure, well-architected, and scalable cloud environments. It typically includes core infrastructure components such as identity and access management, network architecture, security controls, and monitoring tools.
The purpose of a cloud landing zone is to provide a standardized set of best practices for cloud infrastructure management, which can be reused across multiple projects to accelerate cloud adoption, improve security, reduce costs, and enhance agility. By establishing a landing zone, organizations can ensure a consistent approach to cloud infrastructure management and provide a secure and scalable foundation for the migration of workloads and applications to the cloud. This includes defining governance policies, establishing network connectivity, configuring security controls, and setting up monitoring and logging capabilities. Let’s understand them in more detail:
- Defining Governance Policies: Governance policies define rules and guidelines for managing cloud resources, and help ensure compliance with regulatory requirements. This includes policies for resource provisioning, access management, data management, and budget management. For example, governance policies might dictate that only approved users can provision new resources, or that data must be encrypted both in transit and at rest.
- Establishing Network Connectivity: Network connectivity is critical for cloud environments, as it provides access to services and resources, as well as connectivity between different components. Establishing network connectivity involves configuring network infrastructure components such as virtual private networks (VPNs), subnets, and routing tables. This ensures that resources can communicate with each other and with on-premises resources securely.
- Configuring Security Controls: Configuring security controls involves implementing a range of measures to protect cloud environments from threats and vulnerabilities. This includes identity and access management, encryption, network security, and compliance monitoring. For example, security controls might dictate that all user access requires multi-factor authentication, or that all data must be encrypted both in transit and at rest.
- Setting Up Monitoring and Logging Capabilities: Monitoring and logging capabilities are critical for identifying and responding to security incidents and performance issues. This involves configuring tools to monitor resource utilization, network traffic, and system logs, as well as setting up alerts for events that require attention. This enables administrators to proactively identify issues and address them before they become major problems.

During the implementation phase of a cloud migration program, the foundation cloud architecture and operating model are put into effect, and a set of applications identified as “quick wins” are migrated. It’s crucial to take a proactive approach to change management during this phase.
- Cloud foundation and operating model implementation: The Cloud foundation and operating model implementation involves the setup of Landing Zones, including accounts, VPC, network connectivity, IAM Roles, policies, and deployed workflows as discussed above. Shared services and tools are provisioned, and key processes are rolled out in the cloud operating model, with teams mapped to new cloud-centric roles. Subsequent processes are then rolled out, leveraging key learnings from existing implementations to ensure seamless integration with current systems through the installation of selected tools.
- Initial migration: The initial migration involves the migration of a set of applications as quick wins, with varying complexities across different business units. This successful migration helps to understand the portfolio and builds confidence in the applications team, establishing a foundation for repeatable migration patterns.
- Change management: Effective change management is pivotal to the success of a cloud migration program. Change champions are involved to ensure co-creation of future roadmaps and smooth cultural shifts, with continuous knowledge sharing and training to evolve skills and include them in the transformation journey.
