Cloud Connectivity for Australian Businesses: Beyond Standard Internet Access to AWS, Azure, and Google Cloud

For most Australian businesses, the cloud is simply somewhere their software lives. Microsoft 365, Xero, Salesforce, cloud-hosted backups — these services run over the same internet connection the business uses for everything else, and they work perfectly well. Standard internet access is not a compromise for these workloads. It is the right choice.

But for a smaller group of mid-market businesses running more demanding cloud workloads — high-volume data transfer, latency-sensitive applications, regulated environments — the question of how traffic reaches AWS, Azure, or Google Cloud is worth examining carefully. The difference between internet-based access and private cloud connectivity can have a material impact on performance, predictability, and security posture.

This article explains how cloud connectivity works in the Australian context, when standard internet is sufficient, and when it is not. It covers the private connectivity options available through AWS, Azure, and Google Cloud, and offers a practical framework for deciding what your business actually needs.

How Most Australian Businesses Connect to the Cloud (and Why It's Often Fine)

When an employee in a Sydney office opens a file in SharePoint or runs a report in a cloud-hosted business intelligence tool, the traffic follows a straightforward path. It leaves the office via the business's internet connection — whether that is an NBN business service, fixed wireless, or an Enterprise Ethernet circuit — traverses the public internet, and arrives at a data centre operated by Microsoft, Amazon, or Google.

In Australia, the major cloud providers have invested heavily in local infrastructure. AWS operates the ap-southeast-2 region in Sydney and the ap-southeast-4 region in Melbourne. Microsoft Azure has two Australian regions: Australia East (Sydney) and Australia Southeast (Melbourne). Google Cloud runs australia-southeast1 in Sydney and australia-southeast2 in Melbourne. For most Australian businesses, cloud traffic is not travelling across the Pacific — it is going to a facility a relatively short distance away.

The latency reality reflects this. A Sydney business on a quality internet connection connecting to the AWS Sydney region (ap-southeast-2) can expect round-trip latency of roughly 5 to 15 milliseconds. For Melbourne businesses connecting to Melbourne cloud regions, the numbers are similar. This is fast enough for every common business application — email, productivity tools, CRM systems, video conferencing, cloud backups, accounting software, and the vast majority of SaaS platforms.

For these everyday workloads, standard internet access via NBN business or Enterprise Ethernet is not a limitation. The architecture works, the performance is adequate, and there is no business case for spending more on dedicated cloud connectivity. Recognising this is important before exploring the scenarios where it becomes relevant.

When Standard Internet Isn't Enough for Cloud

The circumstances where dedicated cloud connectivity becomes warranted are specific. They are not rare, but they apply to a relatively narrow set of workloads and business types. Understanding these scenarios clearly prevents businesses from over-investing in connectivity infrastructure they do not need, while ensuring that those with genuine requirements identify them correctly.

Very high-volume data transfer. Businesses that regularly move large datasets to or from the cloud — multi-terabyte database migrations, continuous real-time replication between on-premises and cloud environments, or regular movement of large media or scientific datasets — encounter two problems with standard internet. First, the bandwidth required may be substantial enough to compete with other internet traffic. Second, data transfer costs over the public internet can be significant when moving petabyte-scale volumes. A dedicated private connection can offer more predictable throughput and in some scenarios reduces data egress costs.

Latency-sensitive applications. While 5–15ms is imperceptible for most business applications, certain workloads are genuinely sensitive to millisecond-level variation. Financial services firms running algorithmic or high-frequency trading infrastructure care deeply about latency consistency. Real-time analytics pipelines, low-latency database queries serving customer-facing applications, and some industrial or operational technology integrations share this sensitivity. For these use cases, the variable nature of public internet routing — where latency can spike during congestion events — is a practical problem.

Regulated data handling. Some industries operate under compliance frameworks that impose requirements on how data is transmitted. Healthcare organisations handling sensitive patient records, financial institutions with specific data handling obligations, and businesses subject to government security requirements may face regulatory or contractual constraints that effectively rule out public internet transmission for certain data flows. The specific obligation varies by framework, but where it applies, private connectivity is not optional — it is a compliance requirement.

Predictable, guaranteed bandwidth. Standard internet services, including business NBN, are delivered over shared infrastructure. The contention ratio of a connection — how many customers share the same upstream capacity — affects performance under load. For cloud workloads where consistent throughput is operationally critical and cannot tolerate variability, a dedicated connection with guaranteed bandwidth provides a level of assurance that shared internet cannot.

Large-scale private cloud interconnect. Businesses running hybrid cloud architectures — where workloads span on-premises infrastructure and public cloud environments — sometimes need to move substantial volumes of data between these environments continuously. When the on-premises environment is a data centre or colocation facility rather than a single office, and when the data volumes are significant, a dedicated private circuit between the facility and the cloud region becomes worth the investment.

If none of these apply to your business, standard internet is almost certainly the right answer. If one or more apply, read on.

Private Cloud Connectivity Options

The three major public cloud providers — AWS, Azure, and Google Cloud — each offer a dedicated private connectivity product. They are functionally equivalent in concept, though they differ in implementation detail and commercial terms.

AWS Direct Connect

AWS Direct Connect is a private, dedicated network connection from your premises or data centre to AWS infrastructure. Traffic using Direct Connect bypasses the public internet entirely, travelling over a private fibre connection to an AWS Direct Connect location.

In Australia, Direct Connect is available via carrier partners operating at AWS-approved facilities. The connection is provisioned through a network provider or colocation operator who has a physical presence at an AWS point of presence. Speeds are available from 1 Mbps through to 100 Gbps depending on the port type selected, with hosted connection options (where bandwidth is shared on a partner's port) offering more accessible entry points for businesses that do not need a full dedicated port.

The benefits are consistent low latency, predictable throughput, and private routing that does not traverse the public internet. Pricing is based on port speed and the volume of data transferred. For businesses with an existing Enterprise Ethernet or dedicated internet service, the conversation about Direct Connect is typically about whether the workload justifies the additional cost and operational complexity.

Azure ExpressRoute

Azure ExpressRoute is the Microsoft equivalent: a private connection from your network to Microsoft's Azure infrastructure, bypassing public internet routing. It carries the same core benefits — private routing, consistent latency, predictable throughput.

ExpressRoute is available in both Sydney (Australia East) and Melbourne (Australia Southeast) through carrier partners including Australian providers. Circuits can be provisioned at various bandwidth tiers, and the connection can be extended to reach other Microsoft cloud services including Microsoft 365 (though as discussed separately below, ExpressRoute is not the recommended path for M365 specifically).

Like Direct Connect, the practical delivery of an ExpressRoute circuit typically involves working with a network or colocation provider who has a physical point of presence at a Microsoft peering location.

Google Cloud Interconnect

Google Cloud Interconnect provides the equivalent dedicated private connectivity for Google Cloud Platform. It is available in Sydney (australia-southeast1) and Melbourne (australia-southeast2). As with Direct Connect and ExpressRoute, Interconnect traffic does not traverse the public internet.

Google offers two variants: Dedicated Interconnect for direct physical connections at high bandwidth (10 Gbps or 100 Gbps), and Partner Interconnect for businesses that connect via a partner's network at lower bandwidths. For most Australian businesses requiring Google Cloud private connectivity, Partner Interconnect is the practical starting point.

SD-WAN with Cloud Breakout

For businesses already operating SD-WAN infrastructure across multiple sites, private cloud connectivity is not the only way to improve cloud performance. Modern SD-WAN platforms include cloud on-ramp capabilities that direct cloud-bound traffic to optimised paths — either through cloud gateway integrations or by routing traffic to the nearest high-quality internet breakout point closest to the cloud region.

This approach does not provide the same level of isolation as a dedicated private circuit, but it can meaningfully improve performance and consistency for businesses using AWS, Azure, or Google Cloud without the commitment of a full Direct Connect or ExpressRoute deployment. For SMBs and mid-market businesses where cloud workloads are significant but do not meet the threshold for dedicated private connectivity, SD-WAN with optimised cloud breakout is often the right middle ground. It also works well alongside a dedicated or symmetrical internet connection to ensure the underlying path to the cloud on-ramp is high quality.

Colocation and Cloud On-Ramps

For businesses that house servers or networking equipment in a colocation facility, the economics of private cloud connectivity change significantly. Major colocation providers in Australia — including NextDC, Equinix, and Macquarie Data Centres — have invested in cloud on-ramp infrastructure within their facilities. AWS, Azure, and Google Cloud each have points of presence within or directly connected to several of these facilities.

When your hardware is already in a colocation facility that has a cloud on-ramp, a direct private connection to AWS, Azure, or Google Cloud can be established via a simple cross-connect within the building. This avoids the need to provision a fibre circuit from an office location or organise a carrier connection across the city. The cross-connect is typically a short fibre patch in the data centre's meet-me room, and provisioning times are far faster than building a new access circuit from a business premises.

This architecture — servers in a colo facility connected directly to cloud infrastructure — provides private cloud connectivity with minimal latency and without requiring a new access circuit to be built from scratch. For businesses already operating in a colocation environment, it is typically the most cost-effective path to private cloud connectivity. The latency between a server in NextDC Sydney and the AWS Sydney region, for instance, can be well under 1 millisecond when the connection is made via cross-connect.

If your business is evaluating colocation as part of a broader hybrid cloud strategy, the availability of cloud on-ramps at the facility should be a key selection criterion.

What About Microsoft 365 Performance?

Microsoft 365 is one of the most common reasons Australian businesses investigate private cloud connectivity. Teams calls that drop or stutter, SharePoint uploads that feel sluggish, or Exchange Online latency can all prompt questions about whether ExpressRoute is the answer.

In most cases, it is not — and Microsoft itself has made this position explicit.

Microsoft previously recommended ExpressRoute as an option for improving Microsoft 365 performance. The company has since reversed that recommendation. Microsoft's current guidance is that direct internet breakout — routing Microsoft 365 traffic directly to the internet from each office location, rather than backhauling it through a central internet gateway — is the recommended and preferred architecture. Microsoft's network is well-optimised and geographically distributed, and Microsoft 365 traffic from Australia connects to Microsoft's network infrastructure at relatively local internet exchange points.

Forcing Microsoft 365 traffic through a private ExpressRoute circuit can actually introduce unnecessary complexity and routing inefficiency. The right approach for most businesses experiencing Microsoft 365 performance issues is to ensure good-quality internet connectivity, confirm that DNS resolution is pointing to the correct regional endpoints, and check that Microsoft 365 traffic is not being subjected to unnecessary traffic inspection or backhauling through security appliances.

A quality business internet connection with appropriate upload and download symmetry — particularly important for Teams video calls and SharePoint uploads — addresses the vast majority of Microsoft 365 performance concerns without requiring private connectivity infrastructure. If Teams calls are experiencing quality issues, the cause is more likely to be upload bandwidth constraints, local network congestion, or QoS configuration than public internet routing.

Cloud Connectivity for Multi-Cloud Environments

Businesses building complex cloud architectures — using AWS and Azure simultaneously, or combining public cloud with private cloud infrastructure — eventually encounter connectivity requirements that go beyond the standard on-premises-to-cloud model.

Private peering between cloud providers, often called cloud-to-cloud interconnect or inter-cloud networking, allows traffic to move between two different public cloud environments without traversing the public internet. This is relevant for businesses that run workloads split across AWS and Azure, or that need low-latency, high-throughput paths between cloud environments for data replication, inter-service communication, or disaster recovery.

This territory is beyond the practical requirements of most SMBs and is firmly in the domain of mid-market and enterprise businesses with dedicated cloud architecture teams. Options include transit virtual interfaces on Direct Connect, Microsoft's MegaPort integration with ExpressRoute, and third-party network-as-a-service platforms that provide private cross-cloud connectivity. These platforms — sometimes called network exchange providers — operate within colocation facilities and can provision private connections between cloud providers within the same building or campus, often with provisioning available via an API.

For businesses considering multi-cloud architectures, the connectivity design between cloud environments is as important as the connectivity from on-premises to cloud. Getting the architecture right at the outset avoids expensive retrofitting later.

The Practical Starting Point for Most Australian Businesses

The cloud connectivity landscape can appear complex, and the existence of products like AWS Direct Connect and Azure ExpressRoute can give the impression that private connectivity is a standard requirement. It is not. The vast majority of Australian businesses — including mid-market businesses running substantial cloud workloads — operate perfectly well over standard internet connections.

The right starting point is a quality enterprise internet connection sized appropriately for the business's actual requirements. For many businesses, this means understanding what internet speed their applications genuinely need, and ensuring the connection has adequate upload capacity as well as download — particularly if the business is transferring significant data to the cloud or running real-time video communication tools.

If cloud performance issues emerge — latency, throughput, consistency — the investigation should start with the internet connection and local network configuration before jumping to private connectivity. Common causes of cloud performance problems include insufficient upload bandwidth, local network congestion, suboptimal routing through security appliances, and over-reliance on a single internet connection without failover or redundancy.

The decision to invest in private cloud connectivity via Direct Connect, ExpressRoute, or Google Cloud Interconnect should be driven by specific, demonstrable workload requirements — not by a general preference for more infrastructure. When those requirements exist, the investment is justified and the performance difference is real. When they do not, a well-designed internet connection delivers equivalent outcomes at lower cost and complexity.

Frequently Asked Questions

Q: Does Microsoft 365 need a private cloud connection in Australia?

A: No. Microsoft's current recommendation is that Microsoft 365 traffic should use direct internet breakout, not a private connection like ExpressRoute. Microsoft's network is well-optimised for Australian traffic, and routing M365 traffic over the public internet from a quality business connection provides good performance for Teams, Exchange Online, SharePoint, and other M365 services. If you are experiencing M365 performance issues, the cause is more likely to be upload bandwidth constraints, local network configuration, or traffic backhauling than the internet path itself.

Q: What is AWS Direct Connect and do I need it?

A: AWS Direct Connect is a dedicated private fibre connection from your premises or data centre to AWS infrastructure, bypassing the public internet entirely. It provides consistent low latency, guaranteed bandwidth, and private routing. Most businesses do not need it — standard internet access to the AWS Sydney region (ap-southeast-2) is adequate for the overwhelming majority of cloud workloads, including cloud backups, cloud-hosted applications, and most data transfer scenarios. Direct Connect becomes relevant for businesses with very high data transfer volumes, latency-sensitive applications, regulated data handling requirements, or large-scale hybrid cloud architectures.

Q: How much latency should I expect between my office and AWS Sydney?

A: A Sydney business on a quality internet connection connecting to the AWS ap-southeast-2 (Sydney) region can expect round-trip latency of approximately 5 to 15 milliseconds. Melbourne businesses connecting to AWS ap-southeast-4 (Melbourne) see similar figures. This is fast enough for virtually all business applications. Latency variations occur during network congestion events on the public internet, but for most workloads these variations are imperceptible in practice. Applications that genuinely require sub-millisecond consistency are exceptions rather than the rule.

Q: Is standard NBN adequate for cloud-hosted business applications?

A: For most business applications — Microsoft 365, Salesforce, cloud accounting, cloud-hosted VoIP, SaaS platforms — yes, a quality NBN business service is adequate. The key factors are selecting an appropriate speed tier for the number of users and their workloads, ensuring the service has sufficient upload capacity (often underweighted when businesses choose plans), and using a business-grade NBN product with an appropriate SLA. Where NBN has limitations — fixed service areas, maximum speed tiers, shared infrastructure — Enterprise Ethernet may be a better fit for larger or more demanding business environments.

Q: What is the difference between internet-based cloud access and private cloud connectivity?

A: Internet-based cloud access routes your traffic over the public internet to the cloud provider's data centres. Traffic is shared with other internet users, routing paths vary depending on network conditions, and there is no guaranteed bandwidth or latency. Private cloud connectivity — via AWS Direct Connect, Azure ExpressRoute, or Google Cloud Interconnect — provides a dedicated private circuit between your network and the cloud provider's infrastructure. Traffic does not traverse the public internet, latency is consistent, and bandwidth is guaranteed. Private connectivity costs more and requires more planning to implement, but it provides a level of performance predictability and privacy that internet-based access cannot match. For most businesses, internet-based access is the right choice. Private connectivity is warranted when specific workload characteristics demand it.
