If you are migrating your legacy systems to the cloud without doing proper planning, then it can create many problems. In this article, we are going to talk about a few things that you can follow for a successful migration.

First, you need to understand the impact of cloud migration on your enterprise capabilities, mission, and business. Your leadership team should talk about possible outcomes. They should establish a communication mechanism between them.

Your leadership team must create initial documentation of your legacy applications, systems, databases and services that you are moving to the cloud. They should also fix the deadline for this project. The information must be communicated between different staff members.

  1. Break down your infrastructure

You should create a complete model of your application. Your model must include every piece of your application. Make sure to include important things like storage configurations, servers, network configuration, and how you will deploy this application. You should also create a network map. This map will help you in understanding how different components are communicating with each other.

If you have already broken down your infrastructure into individual parts, then you can easily develop a virtualized application environment. There are various tools like containers that you can use for creating your application environment. It has also become easy to implement these complex approaches.

  1. Find your Cloud provider

Once your expectations are set, it is time to find the cloud provider for your company. There are three types of cloud models: public, private and hybrid. If you are not storing sensitive information, then the public cloud network is perfect for you. It is the most cost-effective cloud model. You can save a lot of your operational costs. But, your data will be stored in a public cloud server. If you are storing sensitive information like financial information, then the hybrid or private cloud model is perfect for you. In a private cloud network, only your applications will be running. Thus, you don’t need to worry about data security. But, it is difficult to maintain a private cloud. Thus, most companies are using hybrid clouds. In this, some of your applications will be running in a public cloud network. Your sensitive information will be stored separately in a private cloud. This ensures your data security.

You should find the cloud model which is perfect for your business. It is important to do proper research before selecting any cloud provider. This is also the best time to decrease your operational clouds. Try to select a cloud provider which is providing the most cost-effective option.
