Gone are the days when businesses had huge server rooms to store their data. Modern online firms are quickly shifting towards cloud-based infrastructure to support their growing needs and scale growth effectively. Gartner reports state that in the next 3 years 44.6 percent of small organizations, 33.7 percent of mid-sized companies, and 40.4 percent of big firms plan to switch to cloud.
Most online businesses want to migrate to the cloud quickly without suffering any downtime. With careful planning, it’s possible to ensure the minimum effect of migration on daily operations. In this post, we discuss effective migration strategies that help companies succeed in their cloud migration journey.
Effective Cloud Migration Strategies for your Business
Following a stage-wise implementation is a wise cloud migration strategy that sets companies up for success. We hope these cloud migration steps shall help you plan your migration effectively.
Identify which Applications Should Migrate
Through the readiness reports, you can easily analyze your organization’s gaps and recognize apps for early migration plans. Through cloud-fit analysis, you can categorize applications based on their complexity levels and migration suitability. Ideally, the least complex and the most suitable apps migrate first to the new systems.
To determine application complexity, you can assess its dependency on other apps and servers to function well. Lower dependency indicates a lower complexity level. So, the apps with the lowest complexity levels are ideal for the first move to the new system. This segregation ensures cloud migration processes don’t disturb day-to-day operations.
Here’s a criteria list to select early migration apps: –
- Data and applications from the development or test environments
- Emergency solutions for disaster recovery
- Low impact HR or internal apps
Select the Right Cloud Platform
After selecting the applications, you also need to choose the right platform to deploy them. You can use factors like security, tools supported, compatibility, and cost model to decide well. Broadly speaking, you can choose among public cloud, private cloud, and hybrid cloud.
Public cloud options are awesome for businesses that need resources on-demand without owning or maintaining any hardware or software. While this model provides more freedom from resource maintenance, it compromises on control and privacy concerns. With a private cloud, firms get more flexibility, control, dedication, and security from their resources. This setup does cost a lot of money to establish and maintain. However, it’s the most secure option of the three.
If you want to protect some business-critical data, you can opt for the hybrid cloud model. With a combination of the public and private environments, you can pick which apps need private cloud and which don’t. For 2020, hybrid cloud adoption stands at a whopping 58 percent.
Draft a Comprehensive Migration Plan
In this phase, you create a migration plan that suits you from the various cloud migration processes like re host, rebuild, refactor, retain, or replace. Then, you make a custom migration plan based on important factors like security, customer growth, scalability, business objectives, risks, and governmental regulations.
In this phase, you also choose the right cloud migration process among the following options: –
- Lift and Shift (or Rehost)
- Cloud Native (or Rebuild)
- SaaS Replacement (or Replace)
Pick the Right Cloud Deployment Process
Lift and Shift (or Rehost)
In this migration mode, you move your applications as it is to the new system without changing anything. The new applications completely mimic the original ones in form and function. This mode is an extremely easy, cost-effective, and fast way to deploy apps effectively. However, you may have to bare future optimization costs for performance enhancements.
When to Rehost
- If you desire quick and easy migration process
- If you want to reduce on-premise costs immediately
- If you’re new to the cloud hosting scenario
- If your as-is processes run well and don’t need upgrades
Cloud-Native (or Rebuild)
If you want to benefit from features like elasticity and availability, you should opt for the cloud-native approach. In this approach, you’ll need to reconstruct your apps or recode some of its parts to realize all benefits. Hence, it can take more time and resources to achieve its full potential. If any part of the rebuilding fails, you can always fall back on your old apps.
When to Rebuild
- If your applications are old and need to improve before moving to the new systems
- If you want to scale your growth and boost performance
- If you want to move to a service-based architecture
SaaS Replacement (or Replace)
Here, you replace current applications completely with software as a service (SaaS). This model helps you get rid of IT development costs. However, you can face issues while accessing data and relying on a single vendor for all your services.
When to Replace
- If you want to reduce the number of services and apps to manage
- If you want to improve scalability and accessibility
Implement the Plan Successfully
In this step, you actually transfer apps, infrastructure, and data to the selected cloud platforms. It also includes optimizing existing applications, constructing new cloud-based apps, transporting data, and optimizing architecture. You should focus on creating a completely new operating model that improves innovative capabilities tremendously. You can improve the quality of migration processes through many automation and migration tools. Automating with specialized skills and various accelerators helps improve the journey even further.
The way ahead…
Cloud migration ends when your systems start running on the cloud. However, your work doesn’t end there. Firms must always look to optimize your cloud solutions and make the most of your cloud costs. You can improve your cloud solutions by conducting post-migration reviews, realizing business advantages, enhancing performance, and evaluating migration. So, you always keep up-to-date on your cloud solutions by fine-tuning continuously for organizational growth.
Through a detailed cloud migration plan, companies can safeguard themselves from unanticipated disasters. When 90 percent of companies already use the cloud, you lose out on competitiveness when you don’t. Invest in cloud solutions to enhance your productivity today!
