Cloud migration is one of the biggest trends in business today, with organizations of all sizes and types migrating their operations to the cloud at an unprecedented and rapidly accelerating rate.
With benefits such as cost savings, added value, increased security, flexibility and scalability, it’s no wonder that businesses are migrating in such great numbers.
If you’re considering migrating your company to the cloud, it’s important to know the various strategies and types of cloud infrastructure on offer, in order to make the best decision for your business and ensure that you unlock the benefits the cloud has to offer.
Choosing your type of cloud:
There are three different kinds of cloud that an organization can choose to migrate to, each with its own benefits and features. The type of cloud infrastructure you should choose to migrate to will depend on your business’ individual needs.
This could prove especially useful for businesses that have seen large numbers of employees convert, temporarily or permanently, to remote work during the COVID-19 pandemic.
A private cloud infrastructure may come with a higher price tag, but is particularly suited for larger companies, companies that deal with a high volume of sensitive data or companies that need to optimise security for critical processes.
This flexibility offers companies the benefits of both public and private cloud, enabling them to store sensitive data or critical applications that need to be securely hosted in the private cloud, while reducing costs by running workloads and hosting less-sensitive data in the public cloud.
Choosing a migration strategy:
Once you’ve identified what type of cloud infrastructure you’re going to migrate to, it’s time to begin planning your migration by settling on your migration strategy or strategies. When it comes to cloud migration, there are numerous different ways that you can move your legacy applications and processes into your chosen cloud infrastructure.
This process is often known as “rehosting” and is particularly useful for a business undertaking a large legacy migration within a short timeframe. A key advantage of this process is that it can be largely automated, but applications may require optimisation post-migration.
Generally speaking, refactoring simply sees an application be slightly optimised to run in the cloud, without the core infrastructure being altered.
Rather than being a migration strategy on its own, this is an approach that any company undergoing a cloud migration can take in order save money, decrease the attack surface it needs to defend and refocus its IT team on core processes.
The cloud migration process
Aside from the type of cloud your business is moving to and the strategies it will use to get there, it will also be critical to undertake the following steps in the lead up to and during your migration.
This process is also useful in determining any applications that aren’t critical to the business and can be retired during the migration.
Crucially, assessing your current situation will be the determining factor in whether migrating to the cloud makes financial sense for your firm and, if it does, which provider or type of infrastructure best suits your needs.
Planning also involves thinking about how your business will operate once hosted in the cloud. You’ll need to consider the different levels of access that different employees will have, how the cloud infrastructure will be constructed and how the different areas of the infrastructure will communicate.
When this is in place, your cloud provider will typically offer tools to assist in your migration. For example, if you wish to avoid the risk of human error, your provider can arrange automated processes to aid in the migration.
