Software as a Service (SaaS)
Ready-to-use applications delivered over the internet on a subscription.
- Examples: Microsoft 365, CRM, accounting apps
- You manage: users and data
- Best for: everyday business software
A plain-English guide to cloud computing for business.
The basics
Cloud computing is the delivery of computing services like servers, storage, databases, networking, and software over the internet, instead of from equipment in your office.
Rather than buying, housing, and maintaining your own servers, you use technology on demand from a provider and pay for what you use. Your team can reach the same apps and files from the office, from home, or on the road.
For most small businesses, the cloud isn't one big switch. It's a series of smart moves, like email to Microsoft 365, files to SharePoint, and an aging server to hosted infrastructure, each made when it makes sense.
Spin up users, storage, or servers in minutes, without waiting on hardware.
Available over the internet from any device, anywhere.
Scale resources up or down as your business changes.
Pay monthly for what you use instead of large upfront purchases.
Service models
Cloud services are grouped by how much the provider manages for you. The more you move up the stack, the less you have to maintain.
Ready-to-use applications delivered over the internet on a subscription.
Tools and environments for building and running custom applications without managing servers.
Virtual servers, storage, and private networks you control, running in a provider's data center.
Complete Windows desktops hosted in the cloud and streamed to any device.
Even in SaaS, protecting accounts and data stays with you. Microsoft keeps Microsoft 365 running, but deleted, overwritten, or ransomware-encrypted files are up to you to recover. That's why we pair every cloud service with multi-factor authentication, security settings, and independent backup.
Microsoft 365 management & backupDeployment models
Where your cloud runs matters as much as what runs in it. Most small businesses end up using more than one.
Shared infrastructure from providers like Microsoft, available to anyone over the internet.
Less control over where and how workloads run.
Dedicated cloud infrastructure for a single organization, hosted in a secure data center.
Higher cost than shared public cloud.
A mix of public cloud, private cloud, and on-site systems that work together.
Needs good management to stay secure and simple.
Using services from more than one cloud provider, each for what it does best.
More accounts, bills, and settings to oversee.

Major cloud platforms invest far more in security than most small businesses can. Most cloud breaches come from weak passwords, missing multi-factor authentication, or misconfigured settings, not the platform itself. We lock those down as part of every cloud project.
Microsoft keeps the service running and offers limited retention, but it isn't a true backup. If files are deleted, overwritten, or encrypted by ransomware, you may not be able to get them back. We recommend a separate backup for Exchange, OneDrive, SharePoint, and Teams.
When your apps live in the cloud, your internet connection matters more than ever. We recommend a backup connection with automatic failover, and cloud tools like OneDrive can keep recent files available offline.
Usually, yes. Many business apps have cloud versions, and those that don't can often run on a hosted application or remote desktop server. See App Hosting.
Often, once you count everything: hardware, software licenses, power, maintenance, backups, and replacing the server every few years. The cloud also turns a large upfront purchase into a predictable monthly cost. We'll compare both options for your situation.
In secure data centers operated by our infrastructure partners and cloud providers. You can choose regions in North America, Europe, and around the world to keep data close to your users or within a specific country.
Absolutely. A hybrid approach lets you move what benefits most from the cloud first and keep other systems where they are, all managed together.
With good planning, very little. We migrate in stages, test before cutover, schedule changes outside business hours when possible, and make sure your team knows what's changing and how to get help.
