A few years ago, I was called into a company that had recently completed what leadership described as a “full cloud transformation”. Servers had been migrated, applications had been moved and monthly cloud invoices were arriving right on schedule.
The problem was that nothing actually worked any better.
Users still complained about slow applications. Access requests still took weeks. Backups were inconsistent. Nobody knew who had administrative rights to what. The only real difference was that the problems now lived in someone else’s data centre.
After helping businesses move workloads to cloud platforms for many years, I’ve learned an important lesson: cloud computing solves a lot of technical challenges, but it doesn’t automatically solve infrastructure problems.
If anything, it exposes them.
“Move It to the Cloud” Is Not a Strategy
Cloud platforms are incredibly powerful. They offer scalability, flexibility and services that would be difficult or expensive to build on-premises.
But “move it to the cloud” is not a plan.
It’s a destination.
A strategy should answer questions like:
- What business problem are we solving?
- What applications belong in the cloud?
- What should remain on-premises?
- How will users access services?
- How will security, backup and recovery work?
I’ve seen countless migrations where workloads were simply lifted and shifted into a cloud environment with little thought about architecture. The infrastructure changed locations, but the underlying issues remained exactly the same.
Cloud providers give you tools. They don’t give you good design by default.
Moving a Problem Isn’t the Same as Solving a Problem
One of the most common mistakes in rushed migrations is assuming that changing the hosting platform will fix operational problems.
It won’t.
A poorly designed application running on a physical server remains a poorly designed application when it’s running in a cloud virtual machine.
The same applies to:
- Inconsistent processes
- Poor documentation
- Lack of change management
- Weak security controls
- Misconfigured systems
I once worked with an organisation that migrated several critical servers to the cloud hoping to improve reliability.
After the migration, outages continued.
The root cause wasn’t the servers. It was a poorly maintained application dependency that nobody had documented. The cloud migration changed where the workload lived, but it didn’t address the actual problem.
Good infrastructure work starts with understanding causes, not relocating symptoms.
Network Connectivity Becomes More Important
A surprising number of businesses assume cloud adoption reduces the importance of networking.
In reality, the opposite often happens.
When your systems live in the same building, internal network issues may be less noticeable. Once key applications move to the cloud, your internet connection becomes part of the production infrastructure.
I’ve seen organisations migrate critical systems only to discover that:
- Their internet circuit was undersized
- Wi-Fi coverage was inconsistent
- VPN performance was poor
- Network redundancy didn’t exist
Suddenly, what used to be a minor connectivity issue becomes a company-wide outage.
Cloud services can be highly available. Your connection to them still matters.

Identity Management Matters More Than Ever
Many cloud environments are built around identity.
Users, groups, devices, applications and automation all rely on identity systems to function correctly.
Unfortunately, identity management is often treated as an afterthought during migrations.
I’ve inherited environments where:
- Former employees still had active accounts
- Administrative privileges were scattered everywhere
- Shared accounts were common
- Multi-factor authentication wasn’t consistently enforced
Moving systems to the cloud typically increases the importance of getting identity right.
If identities are poorly managed, cloud services simply provide more places for those problems to spread.
Permissions and Access Control Can Get Out of Hand Quickly
Cloud platforms make it easy to grant access.
They also make it easy to grant too much access.
One common pattern I encounter is the temporary permission that becomes permanent.
Someone needs administrative access to solve an issue.
The access is granted.
Months later, nobody remembers it exists.
After enough exceptions, organisations end up with large numbers of users holding privileges they don’t need.
Good access control requires ongoing review, documentation and accountability.
The cloud provides excellent tools for managing permissions, but those tools still need to be used properly.
Backups Are Still Your Responsibility
One of the most dangerous assumptions I encounter is that cloud automatically means backed up.
That’s not always true.
Cloud providers are responsible for maintaining the infrastructure they operate. That doesn’t necessarily mean they are protecting your data in the way your business requires.
I’ve worked on recovery projects where organisations discovered too late that:
- Data retention wasn’t configured correctly
- Backups weren’t being verified
- Recovery procedures had never been tested
- Critical information had already been deleted
A backup isn’t a backup until you’ve successfully restored from it.
That rule applies just as much in the cloud as it does on-premises.
Poor Planning Creates Expensive Surprises
Cloud pricing is flexible, which is both a strength and a risk.
When migrations are rushed, cost management is usually one of the first casualties.
I’ve reviewed environments where businesses were paying for:
- Oversized virtual machines
- Unused resources
- Duplicate services
- Forgotten test environments
- Excessive data transfer charges
The cloud didn’t create those problems.
Poor planning did.
A well-designed cloud environment can be extremely cost-effective. An unmanaged one can become surprisingly expensive in a very short period of time.
Hybrid Environments Require Better Documentation
Most businesses aren’t fully cloud or fully on-premises.
They’re hybrid.
And hybrid environments are often more complex than either model alone.
Applications may rely on systems that exist in multiple locations. Authentication may flow between cloud and local services. Networking, security and support processes become interconnected.
This is where poor documentation becomes painfully obvious.
I’ve walked into environments where nobody could explain:
- Application dependencies
- VPN configurations
- Identity relationships
- Network paths
- Recovery procedures
Hybrid infrastructure rewards organisations that document clearly and design intentionally.
Everyone else eventually pays for the shortcuts.
Good Infrastructure Thinking Still Matters
Cloud computing is one of the best tools available to modern IT teams.
But it’s still just a tool.
Successful cloud projects start with good architecture, strong identity management, reliable networking, sensible access controls, tested backups and clear documentation.
If you’re planning a migration, don’t focus exclusively on where the workloads will run.
Focus on how they’ll be operated, secured, supported and recovered when things go wrong.
Because after cleaning up more rushed cloud migrations than I can count, I’ve learned that the cloud rarely creates infrastructure problems.
It simply makes the existing ones easier to see.
