5 common myths about cloud migration


Cloud migration can seem like a daunting prospect, especially for organisations that have been running their own infrastructure for years. It's not surprising then that many IT leaders find themselves hesitating, held back by misconceptions and outdated assumptions about what moving to the cloud entails.

Let's take a gentle look at some of the most common myths that prevent companies from taking advantage of the benefits of cloud computing, and see if we can debunk some of these myths.

Myth 1: "It's too expensive to move everything to the cloud."

This is perhaps the most pervasive myth about cloud migration. While it's true that there are upfront costs associated with moving to the cloud, such as data transfer and application refactoring, these are often outweighed by the long-term savings.

In the cloud, you no longer need to invest in and maintain expensive hardware. You can scale your resources up or down as needed, only paying for what you use. This can lead to significant cost savings, especially for workloads that have variable demand.

Additionally, many cloud providers offer cost optimization tools and services to help you monitor and manage your spending. With proper planning and governance, moving to the cloud can actually be more cost-effective than maintaining an on-premises infrastructure.


Myth 2: "Our data is more secure on our own servers."

Security is a top concern for any organization, and it's understandable to want to keep tight control over your data. However, the notion that on-premises data is inherently more secure is a misconception.

Major cloud providers like AWS, Azure, and Google Cloud invest heavily in security, often more than individual companies can afford. They employ teams of security experts, use state-of-the-art encryption, and have robust physical security measures in place at their data centers.

Furthermore, cloud providers typically offer a wide range of security features and services, such as identity and access management, network firewalls, and intrusion detection. These tools can help you implement a strong security posture in the cloud, often more effectively than what's possible on-premises.

Myth 3: "We will lose control over our systems and data."

Another common misconception is that moving to the cloud means giving up control over your systems and data. In reality, you maintain full control over which services you use and how your data is stored and accessed.


With the cloud, you define the access controls and policies. You decide who has access to what resources and under what conditions. Cloud providers offer robust identity and access management (IAM) tools that allow you to grant fine-grained permissions and enforce the principle of least privilege.

Additionally, most cloud services provide detailed monitoring and logging capabilities. This gives you visibility into how your resources are being used, helping you maintain control and governance over your environment.

Myth 4: "The migration process is too complicated and disruptive."

While migrating to the cloud does require careful planning and execution, it doesn't have to be a painful process. Many organizations overestimate the complexity and disruption involved.

Cloud providers offer a variety of tools and services to help streamline the migration process. For example, AWS has the Database Migration Service (DMS) which can help you migrate databases to the cloud with minimal downtime.

Furthermore, I hope you can forgive us for pointing out that enlisting the help of specialist cloud consultants like PCG can make the migration process even smoother. From assessing your current environment to planning and executing the migration, and even optimizing your cloud setup post-migration, a knowledgeable partner can significantly reduce the complexity and risk involved.


Myth 5: "Our current setup works fine; we don't see the need to change."

This is perhaps the most dangerous myth of all. Just because your current setup is working doesn't mean it's optimal. By not considering the cloud, you could be missing out on significant opportunities for cost savings, increased agility, and improved performance (to name but a few benefits).

The pace of technological change is rapid, and what works today may not be the best solution tomorrow. By embracing the cloud, you future-proof your organization, ensuring that you can quickly adapt to new challenges and opportunities.

Furthermore, your competitors are likely already leveraging the cloud to their advantage. By sticking with the status quo, you risk falling behind and losing your competitive edge.

After the fog: Beyond the cloud myths

While it's true that the cloud is not a panacea — even we'll accept that — it’s no exaggeration to say that it does offer significant benefits that are too compelling to ignore based on misconceptions. By understanding the realities behind these common myths, you can make an informed decision about whether cloud migration is right for your organization.

And remember, you don't have to go it alone!
