What is Cloud Migration?
Cloud migration in cloud computing refers to the process of transferring a company’s digital assets, services, databases, IT resources, and applications either partially or entirely to the cloud environment. It also encompasses the transition from one cloud platform to another.

Organizations seek to migrate to the cloud to move away from outdated and increasingly inefficient legacy infrastructures, such as aging servers, potentially unreliable firewall appliances, or hardware or software solutions that are no longer operating at optimal capacity. By embracing cloud computing, these companies aim to experience the benefits associated with this technology.

It is no surprise that the pandemic has triggered a transition to remote work, driving the evolution of cloud migration and the onset of a cloud-first IT infrastructure era. Nearly 70% of companies have accelerated their cloud migration efforts over the past year.

Experts expect a significant rise in the proportion of companies housing the majority or all of their IT infrastructure in the cloud, from 41% to 63% within the next 18 months. Additionally, 60% acknowledge that cloud capabilities have facilitated an increase in sustainable revenue over the past year. As a result, organizations are planning to allocate an average of 32% of their IT budgets to cloud strategy.

Hence, it is widely acknowledged that cloud migration is critical for achieving real-time, updated performance and efficiency. However, the process requires careful analysis, planning, and execution to ensure that the cloud solution aligns with the organization’s business requirements.

When considering a cloud migration strategy, it is essential to understand that the journey extends beyond merely transitioning to the cloud environment. Organizations must also consider how to rebuild or modernize their applications to ensure optimal performance in the cloud. This has led to the growing importance of application modernization as a complementary process to cloud migration services.

Throughout the cloud migration journey, businesses of all sizes may encounter numerous questions and challenges, necessitating assistance from specialized services firms. These firms can provide expertise in various areas, such as lift-and-shift cloud migration, automated language translation, conventional re-platforming, and other classic modernization services.

To sum up, cloud migration involves the transfer of digital assets and resources to the cloud, either partially or completely, and potentially across different cloud platforms. It is an important endeavor for organizations seeking improved performance, efficiency, and scalability, but it requires careful planning, execution, and, in many cases, the modernization of applications to fully harness the benefits of the cloud environment.

How Does it Work?
Transitioning to the cloud can be a transformative endeavor for your entire business. Thus, it is wise to start by examining the cloud journey comprehensively. This method will help you identify the essential capabilities and tasks needed to execute the three primary stages of cloud migration successfully.

Define the strategy and business case.
Companies must first determine the specific business objectives and values they aim to achieve by migrating to the cloud. This involves crafting a strategy for cloud migration, determining which applications to transfer and to which cloud environment, and building the business justification.

Perform discovery and assessment.
To manage risk, companies need to thoroughly assess their current infrastructure, applications, and data landscape. This includes mapping dependencies, evaluating migration readiness, and conducting predictive analyses to identify the most suitable components to migrate and minimize disruption.

Execute the cloud migration
This labor-intensive phase involves modernizing existing applications for the cloud, building new cloud-native applications, and transforming the underlying architecture and infrastructure. Automated tools, specialized skills, and robust program management are critical to migrating smoothly while accelerating the journey.

By methodically understanding and addressing each of these key steps, companies can navigate the complexities of cloud migration effectively to achieve their desired business outcomes.

Types of Cloud Migration
There are seven main types of cloud migration, commonly referred to as the 7 Rs, that companies and organizations can choose from as part of the 7 steps of cloud migration.

Originally termed the “5 Rs” by Gartner, the cloud migration strategies were later expanded to the “7 Rs” to encompass a broader range of approaches. These strategies provide a framework for organizations considering a move to the cloud environment. When planning their cloud migration journey, companies should carefully evaluate which of the 7 R strategies best aligns with their specific requirements, constraints, and objectives. By choosing the appropriate migration path, organizations can optimize their transition to the cloud and realize the desired benefits effectively. These 7 phases of cloud migration include:

Rehost (Re-host): Moving applications from an on-premises environment to the cloud without making any changes to the application code or architecture. This is also known as a “lift-and-shift” approach.
Replatform (Re-platform): Migrating an application to the cloud while making minor optimizations and modifications to take advantage of cloud capabilities. This may involve changing the underlying operating system or database management system.
Refactor (Re-factor): Modifying the application’s code and potentially its architecture to better align with cloud-native practices and leverage cloud services.
Rearchitect (Re-architect): Redesigning and rebuilding the application from the ground up to take full advantage of cloud-native features and services.
Rebuild: Discarding the existing application and rebuilding it from scratch as a cloud-native application.
Relocate (Re-locate): Moving applications or data from one cloud environment to another, such as between different cloud service providers or different regions within the same provider.
Retain: Keeping specific applications or workloads on-premises for various reasons, such as regulatory compliance, security, or performance requirements, while migrating the rest to the cloud.
What are the Challenges of Cloud Migration?
While cloud adoption is a strategic move that can help organizations stay competitive in the digital landscape, there are several challenges that companies need to address when considering a migration to the cloud environment.

The complexities of cloud migration can include issues related to data transfer and compatibility problems with existing systems and legacy tools. If a particular application or tool is not compatible with the cloud environment, it can cause significant difficulties during the transition process.

Effective cloud management requires careful planning and continuous monitoring of resources to ensure optimal performance and cost-efficiency. Additionally, organizations must thoroughly understand and manage the security and compliance implications of moving their data and assets to the cloud. When it comes to navigating the security requirements for cloud migration, the shared responsibility model applies, which delineates the responsibilities between the cloud service provider and the customer organization. However, only a small percentage (8%) of IT and cybersecurity professionals indicate a clear understanding of this shared responsibility model. In essence, the model dictates that while the cloud service provider is responsible for securing the cloud infrastructure itself, the organization is responsible for securing its data and other assets stored within the cloud environment.
