Learn how to migrate to the cloud, why this is the right choice, and how to do so!

Why migrate to the cloud?

The cloud is considered to be the most effective IT environment of all times. With its help, it is possible to host software and data online. Depending on the cloud type, you get the following benefits:

  • Reduced expenses;
  • Improved stability and efficiency;
  • Always online;
  • Advanced flexibility.

These aren’t all the advantages you’ll get. However, they cover the major part of what possibilities become available with cloud technologies.

Cloud migration process

As in any other thing in IT, cloud data migration requires several steps.

1. Planning stage

Before the whole process begins, it is necessary that you come up with a migration strategy and understand why you’re doing it. Evaluate your environment, calculate the requirements for the servers, find a provider or build your own infrastructure, and hire a dedicated specialist. This is a very important stage because it will determine the direction of the subsequent events.

2. Environment selection

Now you have a plan. You know why you need cloud data migration, so it’s time to come up with the cloud model. It can be a public, private, or hybrid cloud. Each comes with individual benefits, so you’d better read our previous articles about all the existing cloud types. Everything depends on your needs and the type of data you work with.

3. Application and data migration

Now comes the most interesting part – app and data migration. It is highly recommended that the migration process starts using the least critical resources of your business. Also, ensure that a backup of all the data is made, just in case.

4. Testing the results

Okay, the cloud data migration was successful. However, you cannot say that everything is done unless you test the system properly. All processes should function as intended.

Cloud migration strategies

There are hundreds of cloud migration strategies. We shall cover only the three most popular options.

1. Lift and shift

The very first approach is basically rehosting and re-platforming your data & apps. Your environment is completely copied to the cloud without any significant changes.

Most of your employees won’t be impacted by this decision because only the teams responsible for security and infrastructure will have to learn some new things to work properly.

While this is the fastest, cheapest, and easiest way to migrate, it still comes with a set of drawbacks. The major disadvantages are poor cost optimization, many skipped opportunities, and optimization issues.

2. App refactoring

Technically, the applications are optimized for the cloud environment and partly rewritten. All the computations and data usage comes from the cloud, meaning that the processes become more effective.

When you start refactoring your applications, start with the most important ones for your business. This will help you deploy critical services without significant delays and increase productivity with time.

App refactoring is a cool approach because your processes still remain online when you begin the optimization of software.

3. Replatforming

This is the last cloud migration strategy you should use. It comes right after the previous two steps are complete. Briefly, refactored platforms are very flexible and scalable. This is where all the required processes are moved online without the usage of local infrastructure.

What are the challenges of cloud migration?

Of course, cloud data migration isn’t that simple, and there are multiple pitfalls. The major issues that a company can face are:

  • System failure
  • Increased costs
  • No cloud exit strategy
  • Lack of productivity.

Regardless of the problem, the solutions must always be planned in advance. Some systems are supposed to be online 24/7, so it is the task of your IT department to ensure its stability.

If it suddenly appears that the cloud isn’t efficient enough and costs more than on-premise infrastructure, there needs to be a cloud exit strategy. Leaving the cloud is as difficult as entering it. This also requires thorough planning so nothing would go wrong.
