The worldwide pandemic accelerated the effective integration of organizations into the cloud and enabled innovation in their businesses by reopening and outwitting uncertainty.
A survey showed that 87% of respondents stated that COVID-19 hastened their cloud migration strategy. It helped them become agile, cost-efficient, scalable, and more productive.
The same survey also showed that almost 80% of the respondents stated that they would complete their cloud migration by 2025. The main drivers for adopting cloud migration are business influence and overall digital transformation.
What is Cloud Migration? #
Cloud migration moves some or all online business processes like digital databases, services, applications, resources, and assets from on-premises or legacy infrastructure to a cloud-based one.
Cloud migration also implies shifting from one cloud to another. Some prominent public cloud service providers are Amazon Web Services, Microsoft Azure, and Google Cloud.
You can understand cloud migration as a physical move in the digital world, where you move data, assets, and applications from data centers instead of carrying physical goods when you move to a new house.
Most businesses adopt a hybrid cloud environment, a mix of public and private clouds with solid communication between diverse teams, or a mufti-cloud setup where they opt for two or more public cloud services to gain more benefits and features from different cloud service providers.
What Are The Types of Cloud Migration Strategies? #
Amazon has redefined Gartner’s cloud migration approaches, the ‘5 Rs’ to the ‘6 Rs. Here are the six main cloud migration strategies that businesses can implement for cloud migration.
Rehost (Lift and Shift) #
Rehosting, also understood as lifting and shifting, involves redeploying your existing application, assets, and data from the current hosting environment to the cloud server.
Enterprises achieve rehosting by automating with tools or manually. Rehosting is the simplest and quickest method to perform cloud migration and can save up to 30% of your costs.
However, with this quick win, you might not leverage full cloud efficiency like automated recovery and self-healing, efficient CI/CD automatization, containerized environments, etc. But since the hard part of migrating is done, it becomes relatively easier to remodel or optimize applications since they are already running on the cloud.
Re-platform (lift-and-optimize) #
Re-platforming, meaning lifting, tinkering, and then shifting, is implementing changes and product advancements in applications to make them cloud-compatible before migrating to the cloud environment and avoiding extra work after cloud migration.
Repurchase(Drop-and-Shop) #
Like moving an existing CMS to Drupal, repurchasing implies changing the current application for a new cloud platform or service. Repurchase also means dropping the existing license and opting for a new license agreement, platform, or service.
Retire (Turning off) #
When enterprises get a handle on the cloud environment, they eliminate a few portfolios that aren’t useful without losing productivity or value. This helps them save resources, boost business, and reduce the complexity of cloud architecture, storage, computing, backup, and licensing.
Retain (Revisiting/ Going Hybrid) #
To maintain the legacy infrastructure of a business, some organizations opt to retain specific IT infrastructure. This model allows companies to migrate what is needed and keep some databases and workloads for security and other reasons.
Reactor (Re-architect) #
Refactoring comes from the powerful drive to augment performance and add new components primarily through cloud-native features. This desire makes organizations re-imagine and re-architect existing environments.
This migration approach may prove quite expensive, but it can prove most fruitful if it is a suitable product-market fit.
Why Do Organizations Migrate To The Cloud? #
Being the prime facilitator of digital business, the cloud has evolved as the prior site for corporations to store data, and most companies have moved their applications to cloud platforms.
Cloud enables limitless access to computer resources for organizations and reduces infrastructure costs of maintaining and running software and hardware. It also frees employees to focus on growth and innovation, augmenting the ROI, competitive edge, and profits from their endeavors.
Benefits of Cloud Migration #
Migrating to the cloud proves bountiful for several reasons.
Enhances Scalability #
To advance businesses in previous environments, organizations had to spare resources for setting up hardware for physical servers and network equipment besides purchasing licensing agreements and storage.
By migrating to the cloud, scaling businesses becomes more manageable and quicker than on-premise as cloud computing supports larger users and workloads.
Reduced Costs #
When you migrate to a public cloud, the cloud provider services lower your operational costs and simplify cloud maintenance, lowering the expenses on IT processes. You can direct these resources to improve applications, innovate, and invent new products.
Improved Productivity #
Cloud migration augments the business performance and user experience. Since the cloud liberates staff, it enhances the organization’s overall productivity.
You can boost productivity by opting for cloud migration models with automation, artificial intelligence, and analytic, saving around 30-50% in continuous functions.
Agile #
Cloud enables organizations to adopt agile methodology by offering flexibility to allow swift changes and decrease the time for obtaining new inventory and repositories.
Enhanced Digital Experience #
Cloud users can access data from the cloud and cloud services from anywhere, providing a better user experience and employees with flexible digital tools.
Secure #
Safety and compliance form the core of the cloud. This feature makes your migration secure and protects classified data and crucial workloads.
How Does The Process of Cloud Migration Work? #
To devise a successful cloud initiative for your organization, you must revisit and revise your existing processes. Cloud brings a significant shift in your business, so getting a comprehensive look at your cloud migration journey and understanding all the variables involved is vital.
Plan the Migration #
Adopting cloud migration is to devise a modern operational model that enables organizations to innovate most effectively.
Your cloud migration journey becomes a success only when the cloud initiative outcomes align with business objectives. You can ask questions to establish business goals and a strong cloud journey management plan for a successful migration, like achieving business value or tracking the effort.
Assess #
With risk assessment, dependency mapping, application discovery, and predictive analysis, you can undertake informed decisions and minimize the risks. Risk management is a crucial element in businesses.
Migration can bring noteworthy infrastructural changes, and its essential to foresee application performance while expecting reduced costs and increased flexibility.
Execute the Move #
After you’ve planned and performed assessments, the next thing is executing the move to the cloud. You’ll need to transform the existing infrastructure, applications, and architecture and create new cloud-native applications for a successful migration.
For seamless migration, you can adopt migration and automation tools to speed up the move with consistency, quality, and reiteration.
What Are The Major Challenges Faced by Organizations in Cloud Migration? #
Cloud migration and adoption isn’t a one-size-fits-all undertaking. It depends on several factors like cost savings, the nature of business, and the benefits of operations and strategy.
Migrating Large Databases #
Data migration usually requires significant time, especially when large databases need to move entirely to function. Cloud providers offer two ways of data transfer: the internet and physical data transfer methods.
Physical transfer methods prove helpful when large databases take longer to transfer via the internet. You can load the data into the hardware and ship it to the provider.
Lack of Strategy #
Most enterprises begin their migration journey without giving much time to planning or strategy.
For a successful migration, organizations need to form end-to-end migration plans and clear business cases since every application and workload has different needs and approaches for shifting.
Cost Management #
Most businesses don’t define clear KPIs to better understand saving and expenditures after migrating to the cloud. For an economically successful move, it’s essential to set KPIs.
Conclusion #
With its core nature of offering scalability, security, and more room for innovation, the cloud has become the prime choice of most businesses.
