Introduction to Cloud Migration
To understand the Cloud Migration Checklist, we will first understand the concept of cloud. Cloud is the network of remote servers over the internet used to store and retrieve data. In layman’s terms, the cloud is the virtual platform over the internet, allowing you to store and retrieve data.
Cloud provides several services like servers, databases, storage, software, and networking. The companies which provide the above-given services are known as Cloud Providers. The major cloud providers are AWS(Amazon Web Services), AZURE from Microsoft, and GCP (Google Cloud Platform). Cloud enables on-demand access to IT resources(computing, storage, software, and networking).
98% of companies are running their own on-premises hardware servers to maintain IT infrastructure, the pandemic has made some adjustments.

What are the benefits of Cloud Migration?
Cloud is a common virtual space where you can place all your data and applications. Any authorized person can access it or work over it without any hustle.
Cloud helps organizations increase their capabilities by providing them powerful resources, enabling organizations to do machine learning like heavy stuff. Cloud provides high-end resources and a production-ready environment.
If you plan to buy hardware for the specific requirement, it becomes complicated to pick appropriate hardware. If the hardware doesn’t suit the requirement, then you have to live with that purchased hardware. But the cloud gives relief from this trouble by providing a variety of resources with different powers. You can choose as per your requirement, or if in a future requirement increases, you can upgrade your hardware resources(CPU and memory).
Just need a few clicks, and you will get a production-ready environment.
You need a good internet connection, and you can access resources, hardware, and services from anywhere you want.
Security is the first concern for any business, and so is a cloud provider consider. Cloud provides highly secure storage for customer’s data by storing it in encrypted form. Also easy to access to the authorized users at any time.
Cloud provides the secure way of scaling your resources. Allows you to set a monitoring tool that will automatically scale up or down resources as per the requirement/need.
Now we get the overview of what the cloud is and what its benefits are. Now we have to consider the below-given points to migrate your workloads over the cloud efficiently.

Prioritize the Applications for Migration
Suppose you have a large volume of applications, but not all applications need to be migrated over the cloud. For example, if an application contains credit card information or some high confidential material, it should be kept in a private cloud. So the first step of the checklist is to make a journal of applications in your organization and migrate accordingly.
What is the Cloud Migration Architecture?
The very next step is you need to specify the Cloud Migration Architecture according to the needs of your applications. A Special team of cloud will work over this point and specify the architecture the organization needs.
There are four types of cloud architecture:
The multi-tenant environment allowed access to IT resources over the internet. If your organization is of small scale, then you can choose public cloud.
This environment is organization-specific. If you have confidential data and want to restrict access to the outer world, you can choose a private cloud.
It is a mix of both public and private cloud both. Sometimes there is a need for both platforms, some data shifted to private, and some are shifted to the public cloud.
The mixture of two or more public clouds. There is a scenario where you find variation in the pricing of cloud service, so you analyze this information and plan the thing accordingly.

Which Cloud Service Provider to Choose (AWS, Azure, and GCP)?
The next item from your checklist is to select the right cloud provider. The major cloud providers are AWS, GCP, and Microsoft. The main parameters to consider while choosing a cloud provider are:
- Cloud provider company profile: During the planning phase, you have to look around the cloud providers present in the market. The major ones are AWS, GCP, and AZURE. Then plan things accordingly.
- Data Security: Ensure the security provided by the cloud providers.
- Pricing: Inspect your project’s cost with respect to each cloud provider and choose the economical one.
- Support: This point is about the customer support provided by the cloud provider. Ensure that customer support is easily reachable.
How to set the priority of Cloud Migration?
Suppose your organization handles several applications. You will categorize applications according to their critical and complexity factor. If the application is complex, you must migrate them last by giving them less priority for migration. If the application is less critical and less complex, then you should give it a high priority and migrate first overcloud.
Lesser the complexity, the higher the migration priority. Higher the complexity, the lesser the migration priority.
How to test the success of a Cloud Migration?
After migrating all the applications, you need to test that the application is working as expected. For testing, you can specify the following parameters to match the expectations:
- Performance testing
- Security testing
- Functional testing
- Disaster recovery testing.
If all the parameters are checked and verified, it means the application migrated successfully. Now you can take advantage of cloud services which will provide more flexibility to your applications.
In my opinion, I would mention some significant points why you should migrate to the cloud. It provides high security to your data. It increases the accessibility of resources and gives you the option to set up dynamic production-ready infrastructure. So If you are migrating to the cloud, you must have gone through the above-given points.
