Cloud migration has emerged as a transformative approach enabling businesses to embrace flexibility, scalability & enhance performance. The rapid evolution of technology is forcing organizations to realize the immense benefits of moving their operations to the cloud. The cloud revolutionizes how businesses manage their resources, processes, and data, from startups to established enterprises.
And as cloud environments become more diverse, organizations now have access to various deployment options like private, public, or hybrid cloud architecture. Some of the key drivers for cloud migration include,
- Efficient and cost-effective backup and recovery capabilities
- Reduced operational costs and freeing up IT resources
- Safe and secure infrastructure
However, a successful cloud migration requires careful planning with a well-defined strategy to ensure a seamless transition while fully capitalizing on its advantages.
With this blog, I’ll discuss the advantages of cloud migration and the strategies that can be employed to achieve it.
What Is Cloud Migration?
Cloud migration involves moving all or a part of an organization’s data, applications, services, security, and other objects from on-site, in-house data center infrastructure to a public or private cloud service accessible to users, on-demand, over the internet. This multiphase process can include assessment, planning, migration & optimization, helping lower risks and costs while simplifying the path to cloud services.
It’s easy to feel confident about the processes and the outcomes while planning and executing the migration process, but it doesn’t consistently deliver the anticipated results. Without implementing migration strategies, even successful migrations can be plagued by challenges.
Advantages Of Cloud Migration
Cloud migration has become increasingly popular as cloud-based applications, platforms & infrastructure offer more benefits at a lower cost. Here are some of the advantages of migrating to the cloud.
Optimizing Operational Costs
Cloud computing offers significant operational cost optimization for companies. Data storage and security measures for on-site servers can be a considerable capital expenditure with recurring workforce costs for companies. Cloud migration helps eliminate these costs by providing maintenance, upgradation, and security related to cloud software and hardware that cloud service providers bear. It allows companies to focus more on their business and provide better services and features to their clients.
Data Security And Backup
The cloud offers more robust security than traditional on-site data centers by encrypting the data and making it safer than other hosting solutions. Cloud technology is updated frequently, along with security profiles, which helps keep up with cybersecurity threats. In addition to these security updates, cloud providers offer various security options such as firewalls, tokenization, and Virtual Private Networks (VPNs). Data loss is disastrous for any business. It’s not feasible for companies to invest in and upgrade for dependable data backup and recovery regularly. The cost of data recovery for on-site servers is prohibitively expensive. Cloud computing services ensure reliable data backup and recovery processes.
Hosting data on local on-site servers is an expensive proposition. Provisioning hardware to meet peak demand, maintenance costs, and increasing the workload on the IT workforce can be limiting for companies. Cloud computing eliminates such challenges, offers scalability per need, and supports more users with larger workloads.
With cloud computing, remote access becomes easy. The data can be accessed from any location using login credentials, making cloud computing enticing for businesses. Improved productivity and flexibility within the workplace can be easily achieved through online remote access facilities.
Elimination Of Routine Tasks
The IT department is free from routine maintenance and day-to-day security by moving the infrastructure to the cloud. It allows the workforce to focus their time and energy on specific needs and eliminates the need for additional staff for routine and expansion workloads.
Cloud deployment allows businesses to expand in new geographic locations worldwide, helping put applications closer to the end users, reducing latency, and improving customer experience.
Software applications must be updated consistently to provide secure and enhanced performance. By issuing enhancement updates, businesses can ensure better functionality is offered to the customers. Regular updates and upgrades to the data security protect crucial information like client profiles, inventory, etc.
6R Cloud Migration Strategy
The “6R” approach often categorizes cloud migration strategies that provide a framework for businesses to decide the best course of action for migrating their applications and workloads to the cloud. The 6Rs stand for:
- Refactor Or Re-Architect: It involves rewriting certain application parts to suit the cloud environment. For example, older databases may need to be updated to move the apps to the cloud. Refactoring is usually done when new functions are added, or the app is modernized to eliminate vulnerabilities.
- Replatform (Lift And Reshape): This involves adding a new optimizing mechanism to the application being migrated to the cloud, like changing the database to another database more suited to the cloud environment.
- Repurchase (Drop And Shop): This involves switching to a different product and typically moving from a traditional license to a SaaS subscription model.
- Rehost (Lift And Shift): Moving an app to the cloud without making minimal changes to the architecture to take advantage of the cloud capabilities. While this looks easy, it can often lead to compatibility issues, especially in migrating old apps. This strategy also may not address the underlying performance issues or vulnerabilities.
- Retain (Revisit): Retaining the applications in the source environment may need refactoring or even the legacy applications that the organization may want to retain but does not have any business reasons to migrate to the cloud.
- Retire: Some applications, like old legacy applications, do not serve any further purpose and may not be needed. In such cases, decommissioning or retiring such applications may be better than moving them to the cloud.
Some key takeaways to achieve successful cloud migration are –
- Understanding the needs, proactive and advanced planning makes cloud migration relatively simple.
- Finding a right cloud partner
- Detailing out the roll-out plan
- Prioritizing information for cloud migration
- Appointing a migration manager.
Cloud migration offers seamless, scalable, and secure platforms and is the need of the times for businesses. It assures companies of operational efficiency, scalability, and sustainability while offering economies of scale and flexibility. The 6R cloud migration strategy provides a framework to evaluate existing IT infrastructure to determine the best approach for migrating to the cloud. It is important to note that migration is not a one-off event but an ongoing process requiring continuous evaluation and optimization.
