Do you want to migrate your business to the cloud, but don’t know what to do or what strategies to follow? Or are you looking for a checklist of key strategies that you can follow for seamless migration? If yes, then we have what you are looking for. Here’s the detailed blog that answers all your questions and helps in cloud migration.
What Does Cloud Migration Strategy Means?
The term cloud migration strategy stands for a well-defined shifting process, where organizations move their data, infrastructure, and applications, from legacy or on-premises systems to a cloud based environment. Shifting to the cloud has become very crucial. It offers scalability without the expenses of increasing infrastructure.
Key Strategies That Make Reliable Cloud Migration Checklist
Here’s a detailed checklist of key strategies that make cloud migration reliable. With the help of these strategies, you can ensure your business applications and systems are not bombarded on the cloud like electrons on the thin film in the 2-slit experiment. Let’s explore the strategies.
Align Cloud Vision with Business Strategy
The very first step in the checklist for reliable cloud migration is defining your business objectives and aligning them with cloud vision.
It is crucial to have a clear grasp of the goals that you want to achieve with cloud migration. You will never be able to choose the right tools and servers without finding out why you are going to the cloud.
With the help of quantifiable goals you get two major benefits; first, the entire cloud migration process feels like a journey and second one is you can identify the most important outcomes.
Create Workable Cloud Adoption Checklist
Once you are done defining the goals and business strategy, then comes the step where you draft a cloud adoption checklist. It reflects the current state of the IT environment.
If we convey it in simple words, in this step you inspect your existing software and hardware infrastructure to understand application dependencies and determine the most and least critical systems.
Then, it is followed by checking compliance and regulatory requirements like HIPAA, PCI DSS, or GDPR and drafting the budget for the migration. This checklist helps you ensure no corners of your infrastructure are left undiagnosed and you encounter no unexpected errors.
Choose Appropriate Cloud Migration Strategy
Now comes, RRRRRR, the “6 R’s” method of cloud migration strategy. Most of the organizations use this method to figure out the best cloud migration path for each application. But, why do we do this?
It is because you can’t handle every workflow in a generic way during the migration. Because IT environments consist of complex, diverse, and specialized workflows that have varying dependencies, performance requirements, and regulatory restrictions.
Understandable, but what are the 6 Rs and what do they do? The six Rs are Rehost, Retire, Retain, Replatform, Refactor, and Rearchitect. What do they do?
- Rehost – Lift and Shift way to move applications and data to the cloud that require minimal or no modifications.
- Retire – Identify and eliminate obsolete applications to reduce security risks and overall IT footprint.
- Retain – Keep some applications and data on-premises due to technical, security, or compliance requirements.
- Replatform – Make minor modifications to infrastructure components or applications to take advantage of cloud-native features.
- Refactor – Rearchitect and rewrite the applications to leverage the capabilities of cloud to improve performance.
- Rearchitect – Design and develop new cloud-native applications and microservices to replace legacy systems.
Analyze Application and Data Dependencies
In business operations, it is noticed that applications are hardly independent of each other. This makes understanding the dependencies between databases, applications, third-party services, and APIs, crucial when you are relocating the entire data to the cloud.
With dependency knowledge, you get the chance to keep your migration process away from time-offs and various other troubles that you might face during execution. Additionally, it also highlights integration challenges or latencies to ensure the interconnected systems move together.
By thoroughly analyzing and recording these relationships, you become proactive and forecast all possible issues before they happen while keeping the migration process continuous.
Choose the Appropriate Cloud Environment
Oh, we’re halfway there. This strategy can not be skipped when you are creating a checklist for cloud migration. It is a major component of the entire plan of transferring the data to the cloud.
As a business, you should not focus on the benefits of the major vendors like Azure, AWS, or Google Cloud, but also take a look at the features of multi-cloud or hybrid deployments. When you are selecting cloud platforms for migration you should prioritize scalability, performance, compliance, and cost-flexibility.
Your provider should not only make the cloud environment a tool of today, but also a path for future growth.
Create a Security and Compliance Plan
In the modern digital landscape, where cyber-attacks have become common, robust security is not just a feature but a necessity. You have to make sure the cloud migration framework you have chosen prioritizes security above every other thing.
Certain security measures such as role-based access control, stored data security and securing data while transferring are a must in every cloud framework. Other than that, it should also have a recovery plan for any unexpected disaster situations and maintain a complete backup of the data.
Apart from all these, you have to make sure your business complies with some specific industry regulations such as HIPAA, GDPR, or PCI DSS, before you release. Such level of detailed security and conformity plans are a type of protective layer that reduces the chances of violation, prevents illegal data access, and supports the change.
Plan and Execute Incremental Migration Waves
Don’t “Big Bang” your cloud migration, it won’t lead anywhere and all the time and efforts might go into vain. For seamless and effective migration, you need to plan and execute the entire cloud migration into incremental waves.
The best way to start is by testing the migration process on low-risk applications. Once you determine, the process is risk free, then you can gradually move onto migrating critical loads by continuously refactoring the process.
You gain a lot of stability when you transform essential business applications and systems at a slow pace. It limits the downtime and ensures the users face minimal or no inconvenience. Incremental migration waves allow businesses to seamlessly migrate to the cloud without affecting the business continuity.
Final Thoughts
With the help of all the strategies your business seamlessly migrates to cloud, all you need is the right development experts who understand legacy systems, security dependency, phased migration, and cloud. With them you just guarantee your entire cloud migration.
