Moving your business to the cloud: a practical guide

Short answer: move to the cloud when your servers are ageing, your business needs to scale, or your team needs secure access from anywhere. Choose the provider that fits the systems you already use, keep data in Canadian regions when it matters, move in stages with a way to roll back, and set budget alerts from day one.

When the cloud makes sense

• Your office server is ageing or a single point of failure.
• Demand changes through the year and you are paying for capacity you use a few weeks a year.
• Your team works from anywhere and needs secure access to systems and files.
• Backups and recovery depend on one person or one machine.
• You are launching new digital products that need to scale without buying hardware.

When Siman, a major regional retailer, needed infrastructure ready for new business demands, our engineering partner led the consulting and a strategic migration to Google Cloud. The work started with an assessment of what to move, when and how, before anything moved. The goal was not to move for the sake of it, but to have room to grow.

When it may not make sense (yet)

The cloud is not the answer to every problem. Pause and think again if:

• Your server is new and fully paid for, the workload is stable, and nobody needs remote access. Moving now may simply add a monthly bill.
• A key application only runs on specific local hardware, such as software tied to a machine on the shop floor. It may need to stay on site, with the rest of your systems moving around it.
• Nobody will own it after the move. Cloud systems still need someone watching access, costs and updates. If no one has that job, plan for it before you migrate.

A “not yet” is a perfectly good outcome of an assessment. So is a hybrid setup, where some systems move and others stay.

Cloud jargon in plain English

A few terms come up in every cloud conversation. Knowing them makes quotes and proposals much easier to compare.

• IaaS (infrastructure as a service): you rent virtual servers, storage and networks, and you manage the operating system and software on top. Closest to running your own server.
• PaaS (platform as a service): the provider runs the servers and operating system, and you deploy your application or database on top. Less to maintain.
• SaaS (software as a service): you simply use the software, such as Microsoft 365, Google Workspace or an online accounting package. No servers at all.
• Region: a geographic area where a provider has data centres, such as Toronto or Montreal. It decides where your data physically lives.
• Landing zone: the secure foundation (accounts, networks, access rules, logging, backups) set up before any system moves in.
• Right-sizing: matching the size of a server or database to what it actually uses, instead of guessing high.

Choosing a provider

The three major providers all have strong security, Canadian regions and a wide range of services. The differences are in fit:

If your business…	Consider
Runs on Microsoft 365, Windows and Active Directory	Microsoft Azure
Relies heavily on data, analytics or Google Workspace	Google Cloud
Needs the widest range of services and integrations	AWS
Mostly needs email, files and business apps	A SaaS approach may be enough, no servers to manage

The best provider is often the one your team and your software vendors already know.

Questions to settle before you choose

1. What do your software vendors support? Some business applications are certified on one platform only. Check before you commit.
2. What does your team already know? Skills you already have save training time and reduce configuration mistakes.
3. Where must your data live? Confirm the provider offers the services you need in a Canadian region, since not every service is available in every region.
4. How will you get support? Understand the provider’s support plans and who you will call at 2 a.m. if something breaks.
5. How easy is it to leave? Favour standard databases and formats where you can, so you are not locked into one provider forever.

Keeping data in Canada

AWS, Azure and Google Cloud all operate data centre regions in Canada:

Provider	Canadian regions
AWS	Canada (Central) and Canada West (Calgary)
Microsoft Azure	Canada Central (Toronto) and Canada East (Quebec City)
Google Cloud	Montreal and Toronto

Note that on AWS, the Calgary region must be switched on in your account before you can use it, while Canada (Central) is available by default.

If you handle sensitive personal, health or financial information, or your clients require it, you can choose to store and process data in Canadian regions. Canadian privacy law (PIPEDA) holds you responsible for personal information even when a provider stores it for you, so choose regions and settings deliberately.

The Office of the Privacy Commissioner of Canada’s guidance on processing personal data across borders makes three practical points: you remain accountable for information you transfer to a service provider, you should use contracts or other means to make sure it is protected to a comparable level, and you should tell people in plain language when their information may be processed outside Canada.

Data residency checklist

• The main region for servers, databases and storage is Canadian.
• Backups and snapshots are stored in a Canadian region too (a common oversight).
• Logs, monitoring and email or file services are checked for where they store data.
• Add-on tools and integrations (analytics, AI services, support tools) are reviewed, since some process data elsewhere.
• Your privacy policy tells customers where their information is stored and processed.

The shared responsibility model

Moving to the cloud does not hand all security to the provider. The provider secures the data centres and infrastructure. You remain responsible for who has access, how accounts are protected, how data is configured and shared, and your backups. Most cloud incidents come from misconfigured settings, not from the provider. Read our cybersecurity basics for small businesses for the essentials.

The provider looks after	You look after
Physical data centres, power and cooling	User accounts, passwords and multi-factor authentication
The hardware and the core network	Who can see and change what (permissions)
The virtualization layer	Storage sharing settings, such as public links
Managed service availability	Your data, your backups and how you restore them

Your backups deserve their own plan. Cloud does not mean backed up. Our guide to cloud backup and disaster recovery explains how to set that up properly.

A migration plan that avoids surprises

1. Inventory. List every system, application and data store, who uses it and how critical it is.
2. Decide what to do with each one. Move it as it is, modernize it, replace it with a SaaS product or retire it.
3. Design the landing zone. Accounts, networks, access control, backups and monitoring set up securely before anything moves.
4. Pilot. Move one low-risk system first and learn from it.
5. Move in stages. Schedule critical steps outside business hours and keep a tested way to roll back.
6. Validate. Check performance, security and data integrity after each step.
7. Optimize. Right-size resources and set up cost and performance monitoring.

Step 2 in detail: the options for each system

Option	What it means	Good for
Rehost (“lift and shift”)	Move the server as it is to a cloud virtual machine	Fast moves, systems you plan to replace later
Replatform	Move with small changes, such as a managed database instead of your own	Cutting maintenance without rewriting the app
Refactor	Rebuild parts of the application to use cloud services fully	Core products that need to scale
Replace	Swap it for a SaaS product	Email, file sharing, standard business apps
Retire	Switch it off	Old systems nobody really uses
Retain	Keep it where it is for now	Systems tied to local hardware or with no clear benefit to moving

Most businesses end up with a mix. The inventory usually reveals at least one system that can simply be retired.

A worked example

Picture a 25-person professional services firm with an ageing file server in a closet, an accounting package on the same machine, and a customer database behind its website.

• Files are replaced with a SaaS file service the team already has through Microsoft 365. Nothing to host.
• Accounting moves to the vendor’s cloud edition, after checking where the vendor stores data.
• The customer database is replatformed to a managed database in a Canadian region, with automated backups.
• The old server is kept read-only for a few weeks as a fallback, then retired.

The pilot is the file migration for one department. Once it works, the rest follows in waves, each scheduled for a weekend with a written rollback step.

Common migration mistakes

• Skipping the inventory. Forgotten systems break on moving day, like a scheduled report or a printer that depends on the old server.
• Moving everything at once. One big weekend leaves no room to learn and no easy way back.
• Copying bad habits. Shared admin accounts and open file shares move to the cloud with you unless you fix them first.
• Oversizing “to be safe”. Cloud capacity can grow in minutes, so start smaller and scale up based on real usage.
• No owner after go-live. Someone must watch costs, access and alerts every month.
• Not testing the restore. A backup that has never been restored is not a recovery plan.

Keeping the bill under control

• Right-size servers and databases to what they actually use.
• Shut down development and test environments outside working hours.
• Delete forgotten resources, old snapshots and unused storage.
• Commit to reserved capacity or savings plans for steady workloads.
• Set budget alerts so a surprise never waits until the end of the month.

Two habits make a lasting difference. First, tag every resource with the project or department it belongs to, so the bill shows who uses what. Second, review costs monthly with whoever owns each system. Costs rarely jump in one day. They creep up as small resources are forgotten.

What to ask a cloud migration provider

Before you sign, ask:

• How will you inventory our systems, and what will we receive at the end of the assessment?
• Which systems would you move, replace or retire, and why?
• How will you keep our data in Canadian regions, including backups and logs?
• What is the rollback plan for each stage, and has it been tested?
• How will downtime be scheduled and communicated to our staff and customers?
• Who owns the accounts and credentials after the project? (The answer should be you.)
• What documentation and training will our team get?
• How will you help us monitor and reduce costs after go-live?

Vague answers to any of these are a warning sign. For more on evaluating partners, see how to choose a software development company.

Beyond servers: using your data

The cloud also makes it easier to bring scattered data together. Dashboards that update on their own replace weekly spreadsheet exports. For Holcim, our engineering partner built a SaaS platform that records and monitors every step of truck loading and unloading in real time, turning operations that were invisible into data the team can act on, including reports of average load times to find bottlenecks.

Once your systems live in the cloud, the next steps become easier: connecting tools so data flows automatically, building reports your managers actually use, and adding AI automation to repetitive work.

Where to start

Begin with an inventory and a cost and risk review of what you run today. From there, the right path, and the right provider, usually becomes clear. Our cloud and data service covers planning, migration, optimization and dashboards, with a team certified in AWS, Azure and Google Cloud, and our cybersecurity service can review your setup before and after the move. Tell us what you run today and we will recommend a plan.

Frequently asked questions

What are the benefits of moving my business to the cloud?

Flexibility to scale up or down, less hardware to maintain, better backup and recovery options, access from anywhere and, in many cases, stronger security than an office server. The cost moves from buying equipment to a monthly bill you can manage.

Can I keep my data in Canada in the cloud?

Yes. AWS, Microsoft Azure and Google Cloud all operate data centre regions in Canada, so you can choose to store and process data here. You still need to check that backups, logs and any add-on services are set to Canadian regions too.

Which is better: AWS, Azure or Google Cloud?

None is best for everyone. Azure fits naturally if your business runs on Microsoft 365, Google Cloud is strong in data and analytics, and AWS has the broadest range of services. The right choice depends on your systems, your team and your budget.

Will moving to the cloud cause downtime?

A well-planned migration keeps it to a minimum. Systems move in stages, critical steps happen outside business hours, and each step is tested with a way to roll back.

Why is my cloud bill so high?

Usually because of resources that are oversized, forgotten or running around the clock when they are only needed part of the time. A cost review, right-sizing and budget alerts typically bring the bill down.

Should I move everything to the cloud at once?

Rarely. Most businesses do better moving in waves, starting with a low-risk system to prove the process, then moving critical systems once the team has confidence and a tested rollback plan.

Is the cloud automatically more secure than my office server?

Not automatically. The provider secures the data centre and infrastructure, but you remain responsible for accounts, access, configuration and backups, and most cloud incidents come from settings the customer controls.
