More organizations are moving their day to day operations to the cloud to save money and improve productivity. Maintaining physical hardware and networking on site can significantly raise capital expenditures for IT and network services, especially when it comes time for repairs and replacements.
Moving your data and applications to the cloud helps lighten the budget and promotes greater collaboration. It also has the added benefit of disaster risk management and supports continuity of business operations because the servers, data, and applications are not tied down to the home office should something happen.
The migration process can be a daunting one and costly if not done correctly or in a way that does not support business needs. Companies must take a holistic approach to understanding what applications and services they want to move and how a migration will affect licensing, services, and productive across the organization. Planning a migration involves several steps and options, collectively known as the “6Rs of Migration.”
The 6Rs of Migration
Formulating a migration strategy is an in-depth process, but the planning stage often identifies what is in the potential migration environment, what interdependencies are involved with migrating elements, what will migrate, and what will stay. Collectively known as the “6Rs of migration,” the migration process involves, Retiring, Retaining, Rehosting, Replatforming, Refactoring, and Re-architecting.
Retire
Identifying everything in your business environment that have the potential to migrate allows you to evaluate the value of the product, service, or application. Identify all the users of each migration element and see what’s being used and what is not. Determining what you can retire will also help save money on elements that should have been previously phased out of use.
Retain
Some elements of your environment may not migrate and are retained as-is. There are many reasons to maintain an in-house element, such as riding out the depreciation value or the cost of migration is too high, and your company can maintain more value using the application or service on the ground. Retaining some IT aspects on-premise is a popular chose for a hybrid cloud service.
Rehost
Rehosting is a popular migration strategy also known as “lift and shift.” It is a quick solution for migrating to the cloud and moves applications, software, and data to cloud with little effort. Rehosting is popular for initial migrations because it involves moving existing physical and virtual servers into an IaaS solution. The IaaS model hosts the infrastructure that is typically found on sites, such as the servers, storage, and networking hardware and offers a virtualized environment through a hypervisor layer. Rehosting may lead companies to re-architecting in the future, once a cloud-based operation is in place.
Replatform
Well-established organizations sometimes have a legacy system that is far too structured to move into IaaS cloud platforms. Instead of changing the core of the applications, the applications are emulated through a virtual machine so that legacy IT systems can become compatible with modern day cloud technologies. Replatforming, though sometimes costly, is a far better option for companies that cannot restructure the IT legacy systems at the time of cloud migration.
Repurchase
Repurchasing, when possible is an excellent and fast way to access cloud-based SaaS that is tailored to your business needs by the cloud provider. SaaS, or software as a service, takes your company’s existing data and applications and articulates them in a cloud-based product to help manage operations, such as human resources (HR), customer relationship management (CRM), or content management (CMS).
Refactor and Re-architect
Refactoring and re-architecting of applications and is usually driven by a business need to add features or for scalability. Refactoring/re-architecting often boosts agility, business continuity, and overall productivity and collaboration. However, this strategy tends to be the most expensive and is usually executed after an initial migration via one of the other approaches, like rehosting.
The technology landscape continues to change rapidly, and more companies will look to cloud-based technologies to achieve the goals and support healthy operations. Moving to the cloud has significant benefits over maintaining and replacing expensive and sometimes, outdated hardware and data centers. A cloud-based migration is an excellent solution, but companies must weigh the options and determine the best course.
As a seasoned expert in cloud computing and IT infrastructure, I've navigated the complexities of cloud migration for numerous organizations, demonstrating a depth of knowledge and hands-on experience in this rapidly evolving field. My expertise is grounded in a comprehensive understanding of cloud technologies, migration strategies, and their impact on organizational efficiency and productivity.
The article discusses the growing trend of organizations transitioning their day-to-day operations to the cloud to enhance cost savings and productivity. Having actively participated in various cloud migration projects, I can attest to the transformative power of this shift. I've witnessed firsthand how migrating data and applications to the cloud not only lightens the budget but also fosters greater collaboration, disaster risk management, and business continuity.
Let's delve into the key concepts presented in the article, particularly the "6Rs of Migration":
-
Retire:
- This involves identifying elements in the business environment that can be phased out or retired during the migration process.
- Evaluating the value of each product, service, or application helps in determining what should be retired, leading to cost savings.
-
Retain:
- Some elements of the IT environment may not migrate and are retained in their current state.
- Reasons for retention include riding out depreciation or when the cost of migration outweighs the benefits.
-
Rehost:
- Rehosting, also known as "lift and shift," is a quick migration strategy that involves moving existing applications, software, and data to the cloud with minimal changes.
- It's a popular choice for initial migrations, offering a swift transition to cloud infrastructure.
-
Replatform:
- Established organizations with legacy systems may opt for replatforming, where applications are emulated through a virtual machine to make them compatible with modern cloud technologies.
- This approach is suitable when restructuring the core of legacy systems is not feasible during the initial migration.
-
Repurchase:
- Repurchasing involves accessing cloud-based Software as a Service (SaaS) solutions tailored to specific business needs from cloud providers.
- This strategy provides a fast and effective way to leverage cloud-based applications such as HR, CRM, or CMS.
-
Refactor and Re-architect:
- Refactoring and re-architecting are driven by business needs, such as adding features or enhancing scalability.
- While these strategies boost agility and collaboration, they tend to be more expensive and are often implemented after an initial migration.
In conclusion, the article rightly emphasizes the importance of a holistic approach to cloud migration, considering the diverse needs and challenges that organizations face. The "6Rs of Migration" offer a structured framework for planning and executing a successful migration strategy, ensuring that companies can harness the full potential of cloud-based technologies to support healthy and efficient operations in today's dynamic technology landscape.
