Cloud migration means moving software and data from a local computer system into the cloud – an internet-based system that can be accessed from anywhere. 

Moving from the old to the new

Traditional, on-premise computer systems involve storing all applications and data on 

a local computer. You access files and software from the computer by logging in directly to that machine when you are physically in the same building. Before the internet was capable of handling large amounts of data, this was the default system. But as the processing and storage capabilities of the cloud have expanded, it’s now possible to host many terabytes of information online and synchronise changes in real time – meaning that the capacity of the cloud for handling apps, files and more is virtually limitless.

Some common cloud-based applications include:

• Gmail
• Office 365
• Sharepoint

These applications sit on the internet, in the cloud, so they are not hosted on your local computer. 

They make use of cloud services such as:

• Google Cloud Platform
• Microsoft Azure
• Amazon Web Services

Today, there isn’t really a question of whether to stick with the old system or switch to the new. All businesses will need to choose cloud migration at some point – it’s just a matter of when and how. 

How does cloud migration work?

Cloud migration can be complicated to implement. The process is often a lengthy one which can disrupt existing ways of working. So, given the cost and complexity involved, it’s natural to ask: “How will cloud migration work for us?”

The first step is to understand the business benefits of cloud migration, which we’ll outline below. With these benefits in mind, you can begin to work towards a detailed cloud migration plan, including a timeline for your data migration. Here you’ll consider how cloud migration will work within your business, making key decisions about what happens during different phases of the project. With careful planning carried out in partnership with experienced data migration experts, your cloud migration project is likely to generate a significant return on investment for your company. 

Benefits of migrating to the cloud

Cloud computing is far superior to traditional on-premise computer systems, bringing a host of benefits for your business. So although switching from a legacy system to a cloud-based solution will take careful planning and investment, the improved efficiency, reduced running costs, continuous updates and access-anywhere flexibility will ultimately make it well worth your effort. Here are some of the major benefits of migrating to the cloud:

• Access your data from anywhere in the world – all you need is a device and a login.
• Keep your data secure – your cloud service provider will provide automatic security updates and comply with the highest security standards.
• Adapt to your changing circumstances with a scalable solution that can grow with your business.
• Reduce operational costs – there’s no need to pay out for your own on-premises hardware, or buy new equipment when it’s time for an upgrade. Instead, you can pay monthly for what you need.
• Integrate all your software, so different apps can talk to each other. This may enable you to automate tasks and save precious staff resources.
• Compete with other businesses in your industry. The more efficient you can make your operations, the better your advantage.

Things to consider when planning your cloud migration

Cloud migration is a major undertaking, involving the data that you depend on day-to-day to keep your business running. So any cloud migration project will require careful planning and management. You will need to anticipate every step in advance, and ensure that you have contingency plans to guarantee the safety and security of your data assets.

To get the most out of your cloud migration project, here are the main things to consider:

• What is your existing IT infrastructure? To ensure a smooth migration, you will require an inventory of all the hardware and software in your current environment. 
• Will you require new software and licences? If you are running a legacy system, it’s likely that you may need to switch over to newer, cloud-based applications for many of your operations. 
• What type of approach do you want to take to your data migration? Many companies favour a phased approach, where the migration takes place one step at a time. At a certain stage in the project you are likely to have both your legacy system and your new cloud system working side by side. This can help you to keep essential functions running continuously at all times throughout the process.
• What is your backup plan? If something goes wrong during your cloud migration project, it’s vital to protect your data. Have a plan in place so that you can roll back the migration at any stage of the process, to guard against data loss.

Top tips to ensure a successful migration

Moving large volumes of data into the cloud is no mean feat. But with expert help and careful planning, it’s likely to be one of the best business moves you will make. Here are some tips to ensure that your data migration is successful:

• Build your business case for the change. You’ll discover just how much of a difference your data migration could make, and the hard facts and figures will make it easier to convince others.
• Get everyone in your organisation on board. You will need buy-in from senior management, but also from the people who work with your computer systems every day.
• Work with a reputable data migration company with a track record of successful cloud migration projects.
• Use a migration tool such as Azure Migrate to ensure a comprehensive and efficient migration process.
• Once the main job is over and you have migrated to the cloud, there may be a period of adjustment. Continue to monitor performance and be prepared to make further small changes to get the most out of the cloud.
• Invest in training and staff development. It’s important to ensure that everyone in the organisation understands the full potential of cloud computing, and utilises its capabilities.
