Microsoft Defender for Business: What You Need to Know

We know the IT industry can sound complicated, and navigating terms like on-premises infrastructure and cloud computing may feel overwhelming–but don’t worry, today, we’re here to help clarify both concepts, understand their differences, weigh the pros and cons and help you decide which option may best suit your organisation.
On-premises is the more traditional approach, where organisations manage their IT systems in-house or through a dedicated internal IT team. Physical equipment—like servers, storage, networking gear and software—is stored and maintained on-site.
✔️ Keep full control as the data stays on-site
✔️ Manage your hardware, software and policies, making it a big plus for businesses with tight compliance requirements
✔️ Higher upfront cost but long-term savings if workloads are steady.
✔️ Customise the setup to your exact needs and easily integrate it with what you already use
❌ Physical risks such as fire or power outage can all threaten on-premises systems
❌ Adding capacity means buying and installing new hardware, which takes skill, time and money
❌ Regular updates, patching, and hardware replacements
❌ If a critical component fails, recovery could take hours or even days unless you’ve invested heavily in backups and failovers
Cloud computing, on the other hand, allows access to servers, storage, databases, software, and other IT resources over the internet. Rather than hosting systems on your physical premises, everything runs remotely on infrastructure owned and maintained by a third-party provider.
The 3 types of cloud computing include:
✔️ No need for expensive hardware purchases. You pay a subscription or usage-based fee, making it more cost-effective.
✔️ Scalable, as you can instantly increase or decrease resources as needed without delay.
✔️ Your cloud provider will handle backups, maintenance and updates—freeing your IT team for other projects.
✔️ Cloud platforms offer native tools for AI, machine learning, automation and analytics.
❌ While providers invest heavily in security, you still rely on them to keep your data safe.
❌ You may not have full visibility into where or how your data is handled.
❌ If your cloud connectivity drops, so does access to your cloud services.
❌ Not all providers meet Australian data residency and privacy requirements, especially for sensitive industries.
Now that we’ve covered the definitions, let’s explore the differences between them:
| On-premises | Cloud | |
| Location | All hardware and software are hosted locally at your organisation’s site. | Hosted by a third-party provider. |
| Cost | Involves high upfront investment in hardware, software and maintenance. | Operates on a pay-as-you-go model with no initial hardware costs; expenses scale with usage. |
| Scalability | Requires purchasing and installing additional physical resources. | Highly scalable; resources scale up and down. |
| Security and control | Full control over systems, security configurations and data. | Control is shared; the provider handles infrastructure and security, with limited user-level configuration. |
| Maintenance | Your IT team handles all updates and repairs. | The provider takes care of it all—updates, fixes, and performance. |
| Disaster recovery | Requires an internal disaster recovery plan, including backup hardware and storage. | Disaster recovery can be built into services, with automatic data backups and replication across multiple locations. |
When helping clients decide between on-premises and cloud, we often start with this: What are you trying to achieve, and what does your environment look like? There is no one-size-fits-all answer. Both systems have their place.
Ultimately, it’s important to assess your current IT environment and understand what your business truly needs. There’s no universal right or wrong answer—what matters most is that your systems run reliably and support you when needed.
Here are some cases where we recommend each:

If neither model feels like a perfect fit, don’t worry. For many businesses, the best solution isn’t one or the other but a mix of both. A hybrid model combines on-premises infrastructure with cloud services, letting you keep critical systems in-house while shifting less sensitive or more flexible workloads to the cloud.
Hybrid systems can:
Hybrid solutions are especially helpful for businesses that are transitioning or need to maintain older systems while exploring cloud capabilities.
Before starting any cloud migration or on-premises installation, strategic planning is key. This involves a comprehensive architecture assessment where you’ll need to understand how your infrastructure is built and plan for the migration setting where everything will go, how data will flow and scale, the communication between servers and how security will be managed.
Once that’s settled, we move on to the migration process, which includes:
Once installed, the post-migration should involve system monitoring, regular updates and patching, security checks and ongoing performance optimisation.
In such a complex industry, the right partner can make a difference if you’re thinking about moving to a cloud-based or on-premises solution. Here are some factors to consider for choosing the right provider:
Expertise and experience:
Look for a partner with a proven track record to ensure they have actual experience with businesses of your size and complexity.
Customisation and scalability:
Choose a partner who can tailor solutions to your needs and scale as your business grows, whether in the cloud or on-site.
Security and compliance:
Look for strong security practices and industry compliance expertise, regardless of your infrastructure.
Migration support:
For cloud, this means smooth data transfers and minimal downtime. For on-premises, it involves setting up infrastructure efficiently.
Customer-centric approach:
Your IT partner should be collaborative and responsive, acting as an extension of your team to address challenges and improve your IT strategy.
