Data Centre management and maintenance: In-house vs outsourced Australia – Updated 2026

Do you know which data centre management and maintenance structure is best for your organisation – outsourced or in-house? Find out the pros and cons of both. 

Should you manage your data centre yourself or outsource it to a specialist data centre management provider?  

Growing infrastructure demands are prompting IT and business leaders to revisit this decision. And they’re under pressure to get it right. Data centres sit at the core of every organisation’s operations. So, managing them effectively is essential for ongoing performance, reliability and operational continuity.  

Data centre management is the process of maintaining and supporting your data centre’s day-to-day operations. It includes data centre maintenance, monitoring, security, capacity planning and adherence to relevant compliance requirements. Effective data centre management maximises performance, reliability and resilience, ensuring your infrastructure can meet the ongoing needs of your organisation. 

In-house and outsourced data centre management each have their unique advantages and challenges. Ultimately, deciding which model is best for your organisation will depend on several factors, including your team’s capability, budget and compliance requirements.    

For most Australian organisations, outsourcing data centre management delivers greater cost efficiency, higher uptime and better compliance outcomes compared to in-house operations.    

Why? Because modern data centres are complex. Powering today’s high-performance, always-on IT systems requires more than just IT generalists. To effectively manage and maintain a data centre, you need a diverse skillset. This includes expertise in optimising environmental conditions (such as power and cooling), hardware lifecycle management, security and compliance, to name just a few.    

In this guide, we’ll compare outsourced and in-house data centre management, to help you decide which model is best for your organisation.  

Managing your data centre in-house: The full picture   

Let’s cut to the chase. When all is said and done, the number one reason why organisations keep data centre management in-house is control. In-house data centre management gives you complete control over every aspect of your data centre’s, and therefore your organisation’s, operations. But with it, that means full responsibility over keeping it operational.  

The benefits of in-house data centre management and maintenance.  

Control and customisation: 

• Direct oversight of all infrastructure decisions: You’re in charge of how your environment evolves, so you can ensure every change aligns with your operational and compliance needs. 
• Full authority over physical access, security controls and on-site procedures: This lets you set and enforce your own access standards, which you can monitor and change as needed. 
• Custom configurations for specific requirements: You know your environment better than anyone. In-house data centre management lets you tailor your infrastructure to the exact performance, resilience and regulatory demands of your applications. 
• Direct management of security protocols: This lets you apply your policies consistently across your environment, closing gaps or enforcement inefficiencies that can appear when multiple providers manage different layers. 

Perceived cost savings: 

Managing your data centre in-house means you don’t have to pay for anything you don’t own, or anyone you don’t directly employ. That means:   

• No monthly service fees from third-party data centre maintenance providers: You control every cent that goes into data centre maintenance and management.  
• Full ownership of equipment: No rental agreements or dependency on external providers, which can reduce long-term operating costs. 

Challenges of in-house data centre management and maintenance   

Staffing requirements and costs 

 All infrastructure and data centre management duties fall to the in-house team. That means:  

• 24/7 coverage requirement: Data centres require round-the-clock operations. To achieve this with in-house staff, you need a minimum of 3-4 dedicated technicians. That’s if everything goes right and runs smoothly, which at times can be a big if.  
• Specialist skills needed: Not just any team member will do. Data centre environments demand engineers with well-rounded expertise across power, cooling, networking and infrastructure management. 
• Staff salaries: Because of their specialist skillsets, data centre technicians and engineers often command higher-than-average full-time salaries.  
• Staff turnover costs: Salaries are far from the only staffing costs. Recruitment, onboarding and training and retention initiatives create ongoing overheads. On the other side, you risk losing critical operational knowledge with every departure. 
• Additional staffing: To keep your data centre running smoothly with an in-house team, you’ll need additional headcount to cover leave, sick days and training periods.  

Technical expertise 

Effective data centre maintenance requires a set of specialised skills, including: 

• HVAC maintenance: Requires specialised knowledge of data centre cooling systems and ongoing preventative maintenance to keep temperatures stable and equipment protected. 
• UPS maintenance: Involves managing battery systems, power distribution and regular failover testing to ensure uninterrupted operations. 
• Infrastructure complexity: Redundancy measures (such as N+1 or 2N redundancy), environmental monitoring and multi-layered systems add operational complexity that must be actively managed. 
• Ongoing training: To stay current, teams need ongoing upskilling in new technologies, vendor certifications and safety protocols. 
• Emergency response: To handle faults and restore services quickly, you’ll need a rotation of on-call team members with advanced incident management expertise.  

And as data centres get more complex, the requirement for technicians with specialist expertise will only increase. Finding and keeping these skills in-house can be a burden, whether you’re overspending to cover all bases or going without some to keep resourcing cost-efficient. 

Capital and operational costs 

• Equipment lifecycle costs: Critical infrastructure typically requires refresh cycles every three to five years, creating ongoing capital expenditure. Under-resourced maintenance can cut hardware’s lifespan by more than half, adding to the long-term cost of maintaining your own infrastructure.  
• Facilities management costs: Maintaining power, cooling and physical security systems contribute significant operational overheads. 
• Total cost of ownership: Costs extend well beyond hardware, including space, utilities, insurance and maintenance contracts. Then there are the shadow costs: Testing equipment, spare parts inventory and monitoring tools add additional expenses.  
• Lack of standardisation: Without the proper investment in data centre management, larger organisations with multiple data centres often become fragmented and siloed. This can lead to inconsistencies in applying data centre management standards, if such standards exist at all.  

Compliance and security overhead

Meeting the relevant regulatory compliance obligations adds another layer of complexity to in-house data centre maintenance. These may include:  

• ISO 27001 certification: Maintaining certification requires continuous audits, evidence collection and alignment with information security controls. 
• Data sovereignty in Australia: Verifying physical data location and enforcing strict access controls increases operational and security overhead. 
• Audit requirements: Regular internal and external reviews demand consistent reporting, documentation and control validation. 
• Security clearances: Background checks for staff with physical access add time, cost and administrative complexity. 
• APRA compliance: For financial services organisations, meeting CPS requirements adds ongoing governance, documentation and supplier-management obligations. 

If you’re managing your data centre in-house, you’re responsible for all these yourself. With budgets and resourcing in mind, it’s easy to skimp on these essential services, or even disregard them entirely.  

Outsourcing to managed service providers 

Outsourcing is when you engage a specialist data centre management provider to maintain your data centre’s infrastructure, operations and support. It involves:  

A shared responsibility model, where your and the provider’s responsibilities are defined and documented as part of the service agreement.  

SLAs that define the minimum level of service the provider must guarantee.  

Data centre management outsourcing can apply to your existing on-premises data centre, or to a co-located or fully managed data centre hosted by a specialist infrastructure provider, such as Interactive. 

 Whichever way you go, outsourcing frees your organisation from the burden of keeping your data centre running smoothly to meet operational and regulatory expectations.  

Benefits of outsourcing data centre management and maintenance 

Expert teams and 24/7 support: 

• Dedicated specialists: Certified data centre engineers and technicians provide deep expertise across critical infrastructure. 
• Round-the-clock monitoring: A 24/7 Network Operations Centre delivers constant visibility and rapid issue detection. Dedicated staffing means you get the same level of monitoring outside business hours as you do within them. 
• Immediate response: On-site support is available within agreed SLA timeframes to minimise disruption. Interactive provides fast SLAs of up to two hours.  
• Remote hands services: Technicians can perform routine tasks on your behalf without needing to go onsite, keeping support efficient. 
• Smart hands services: When you need experts onsite for complex procedures, troubleshooting and infrastructure changes, a data centre management provider ensures the right people are available.  

Streamlined operations 

• Built-in efficiency: Thanks to their scale and breadth of partnerships, an external provider can offer better internet connectivity and pricing options. They’ll also be able to utilise redundant internet and power connections, which will help maximise uptime. 
• Offsite backup: Data centre management providers offer mirrored data centres, giving you a cost-effective backup environment for disaster recovery purposes.  
• Enhanced security: Robust physical and logical security frameworks protect sensitive systems and information. Data centre management providers continually apply the latest security best practices to keep your data centre protected from current and emerging threats.  
• Tracking and reporting: Specialists constantly monitor critical infrastructure to avoid wasted operational costs and potential downtime. 
• Audits: Data centre specialists carry out regular, detailed audits to identify any potential issues before they impact operations.  

Infrastructure expertise 

Specialist data centre management and maintenance providers offer expertise in:

• Professional maintenance: Scheduled HVAC servicing, UPS maintenance and power distribution testing ensures your infrastructure remains reliable and compliant. 
• Environmental monitoring: Continuous tracking of temperature, humidity and power quality allows for early detection of conditions that could impact uptime. 
• Redundancy systems: Built-in, expertly managed N+1 or 2N redundancy protects critical systems from single points of failure. 
• Backup power systems: Tested generators, UPS systems and dual power feeds maintain continuity during power disruptions. 
• Physical security: Multi-layered access controls, 24/7 surveillance and on-site security personnel safeguard equipment and sensitive data.

These skills, coupled with a provider’s access to parts and vendor-certified staff, work together to maximise the lifespan of your data centre equipment.  

Predictable cost model 

When you outsource data centre management, you’re investing in long-term cost efficiency and certainty. Data centre management providers include everything you need to run your data centre effectively in their upfront pricing. There are no hidden or surprise costs.    

• Operational expenditure: Monthly billing replaces large capital outlays and fluctuating resourcing costs, such as hiring and training. 
• Comprehensive services: Maintenance, monitoring, security and compliance are bundled into a single monthly fee. 
• No staffing overhead: You avoid the recruitment, training and turnover costs that come with maintaining an internal data centre operations team. 
• Budget certainty: Fixed, predictable costs support accurate planning and remove the risk of sudden equipment failures, which are often caused by a lack of preventative maintenance. 
• Scale with confidence: Outsourcing allows you to add or reduce capacity as needed without significant upfront investment.

Built-in compliance 

Keeping up with compliance obligations puts further pressure on data centre management. For example, you might put up with dips in performance and availability to save costs during low-traffic periods. Regulators that demand always-on operations won’t.  

Data centre management providers will also come with years of experience in meeting regulatory compliance obligations, such as ISO 27001 and APRA compliance for financial institutions. As for audits, ongoing compliance reporting and documentation are included as part of any reputable data centre management provider’s service. 

Service level guarantee 

A service level guarantee is a provider’s commitment to keeping your data centre running. To do this, they will offer:  

• An uptime guarantee: Providers typically offer 99.9% or higher uptime commitments in their SLA to ensure consistent availability. 
• Response time commitments: These defined timeframes outline how quickly the provider will acknowledge and address any issues. 
• Break-fix support: Immediate response for equipment failures to minimise downtime. 
• Escalation procedures: Clear escalation paths ensure critical incidents are resolved quickly and by the right teams. 
• Preventative maintenance schedule: Regular servicing reduces the likelihood of outages and performance issues. 

 Geographic redundancy options 

There’s a lot of risk keeping everything in one place. Outsourcing to a specialist data centre management provider means you can leverage dedicated infrastructure, either as a primary environment or backup in case of emergency.  

• Multiple locations: A provider’s network of data centres (such as Interactive’s data centres in Brisbane, Sydney and Melbourne) offer geographic diversity for critical workloads. 
• Disaster recovery: Built-in failover between facilities ensures your services can be restored quickly, by experts, during major incidents. 
• Business continuity planning: Data centre management providers’ infrastructure supports continuity strategies without requiring additional investment from your team. They can also support continuity planning at your on-prem data centre.

Challenges to consider when outsourcing data centre management

Vendor reliance:  

When you outsource data centre management, you’re outsourcing the burden of day-to-day maintenance, but not the responsibility of keeping your data centre running. That means you’re reliant on a vendor for basic tasks like physical access and change requests, while remaining accountable for it in the eyes of your customers and leadership team. This dependence can also complicate any future decision to switch vendors or bring your data centre management back in-house. That’s why choosing the right data centre management provider is crucial.

Less flexibility for highly custom environments:  

Every organisation has unique IT requirements, but some are more unique than others. While data centre management providers are trained to manage the baseline of a modern data centre, highly customised environments may not have a perfect match, at least at the outset. These setups often require deeper discovery and tailored runbooks. To mitigate this, select a provider with broad, proven expertise. This context will ensure they can get to know your environment quickly and sustainably support it long-term. 

The true cost of data centre management 

The hidden costs of in-house data centre management 

Running an in-house data centre carries significant operational and financial overheads that are often underestimated. Staffing alone is a big portion of the expense. Achieving 24/7 coverage typically requires three to four data centre technicians, plus one to two data centre engineers for specialised support. Add recruitment, onboarding, ongoing, training, certifications and additional staffing to cover leave, and costs can escalate quickly. 

Infrastructure and operational expenses add another substantial layer. To stay operational, you must fund:  

• Hardware refresh cycles every three to five years. 
• Facility costs such as power, cooling and space. 
• Maintenance contracts for critical systems, including: HVAC maintenance, UPS maintenance and fire suppression.  
• Environmental monitoring tools. 
• Spare parts inventory. 
• Insurance. 
• Multi-layered data centre security. 

Even if you’re happy to pay for all this, having your in-house team take care of it all efficiently and effectively is another story. That’s a lot to expect from a baseline headcount of 4-6 data centre management professionals.  

That’s not all. Compliance requirements introduce further burden. Meeting regulatory standards such as APRA requirements, PCI DSS, ISO 27001 certification and staff security clearances require ongoing documentation, governance and specialist consultancy support. Risk mitigation, such as implementing redundancy across key systems, further increases capital and operational spend. 

How outsourced data centre management delivers cost efficiency  

There are many different costs involved in running a data centre. Some of these, such as staff costs, external security reviews and urgent hardware replacements can be unpredictable. Outsourcing consolidates these expenses into predictable monthly fees. These fees cover everything required to run your data centre, including: Power, 24/7 monitoring, hardware maintenance, HVAC maintenance, UPS maintenance, physical security, compliance certifications and rack space (if required).  

A shared infrastructure model that’s managed by the provider drives these efficiencies up even further. They deliver economies of scale and enterprise-grade redundancy at a fraction of the in-house cost. With no major capital outlays for refresh cycles and significantly reduced operational overheads, a shared infrastructure model streamlines data centre management.   

Ultimately, organisations that outsource data centre management and maintenance typically see both efficiency gains and costs savings as a result.  

What to keep in mind when comparing the cost of in-house vs outsourced data centre management  

When done right, outsourced data centre management is far more cost-effective than having an in-house team. But plenty of organisations might not see it that way. That’s because data centre management providers, by design, deliver the highest standards in data centre performance and efficiency. This includes 24/7 staffing, preventative maintenance, environmental monitoring, N+1 redundancy, audit-ready documentation and enterprise-grade data centre security. In reality, most organisations don’t operate their in-house environments at this standard consistently, if at all. That’s not because they don’t want to, but because the skills, headcount and capital investment required are difficult to sustain. As a result, the cost comparison is often between a fully mature outsourced model and an under-resourced in-house model that carries higher operational risk.  

Paying a premium for in-house control is one thing. But trying to make do with minimal resources will lead to inefficiencies that pile up and end up costing you much more in the long run.   

Compliance requirements for Australian data centres 

Australian organisations must meet strict regulatory and security obligations when operating or outsourcing data centre infrastructure. Data sovereignty laws require certain data to remain within Australian borders, supported by verifiable physical infrastructure locations, controlled access and detailed audit trails. Providers must offer full transparency about where their environments are hosted.

For regulated industries, APRA standards add another layer of obligation. These include outsourcing governance, service-provider oversight and clear requirements for business continuity and disaster recovery. ISO 27001 further strengthens data centre security through mandating documented processes, independent audits and continuous improvement.

These expectations must be built into every aspect of data centre operations, whether on-premises or in a colocation facility.

Managed data centre providers can reduce the compliance burden by supplying pre-certified facilities and/or providing established documentation and regular audit support. This helps your organisation maintain strong governance across your data centre infrastructure.

In-house vs outsourced data centre management: Which is right for your organisation?

Now you’ve heard the pros and cons of each model, it’s time to make the decision: in-house or outsourced data centre management?   

When to go in-house 

In-house data centre operations may be best suited to your organisation if:  

• You have a highly classified environment. 
• You’re a large organisation with a dedicated data centre and facilities team already in place. 
• You have an extremely specialised environment with unique technical requirements that aren’t easily supported.  
• Cost isn’t a factor in your decision – at all. You’re happy to pay a premium to build and maintain an in-house data centre management and maintenance capability.  

These requirements exist, but they’re uncommon 

For the vast majority of organisations, outsourcing data centre management delivers stronger outcomes. Fully managed data centre services offer expert maintenance, 24/7 support and built-in compliance tailored to your requirements. Providers also offer redundancy, advanced data centre security and geographic diversity, with facilities across Australia. They offer all this at predictable ongoing costs, giving you long-term budget certainty.  

 That’s why in most cases, outsourcing delivers both cost reductions and capability uplift. It gives you a level of resilience, compliance and operational maturity that would be prohibitively expensive to replicate internally. And finally, with a reliable data centre run by a specialist provider, you can keep the focus on your organisation, knowing your infrastructure’s always ready to meet your needs. 

What if you don’t want to compromise?  

 A hybrid model is where you maintain an in-house data centre management team but rely on outsourcing for specialist expertise and overflow staff. Through services like Interactive’s Data Centre Anywhere, your organisation can get flexible access to data centre management specialists on an as-needed basis. So, if you have some in-house capability but need specific services, such as vendor-certified engineers to maintain your hardware or environmental monitoring expertise, you can get just that, without having to pay for anything else. This gives you the best of both worlds. You get the control of an in-house team, while leveraging the benefits of outsourcing to make your data centre more efficient. 

Ultimately, each option has its own strengths and drawbacks. So, when considering how best to meet your organisation’s data centre needs, it’s essential to consider the full range of factors.
