National Digital [hosts in Australian regions by default](/governance/information-security-and-privacy/) and can evidence the hosting region for every component of a system on request. **Where this hub sits** · 1 of 22 areas Areas this page covers - Cloud, security & support [Open the full map on the homepage](/#systems-map-hero) **Quick answer:** Cloud engineering designs and operates the infrastructure, automation and integration layer connecting cloud platforms, legacy systems and SaaS tools such as Xero and HubSpot. *Last updated 10 November 2026* *Quick answer* ## What is cloud engineering? *High confidence · Verified 13 Oct 2026* Cloud engineering is the discipline of designing, building and operating the infrastructure, automation and integration layer that lets applications run reliably on cloud platforms such as AWS, Azure or Google Cloud. **Additional Context:** For Australian businesses running Xero, MYOB, Shopify or HubSpot alongside custom or legacy systems, the practical work is less about greenfield cloud builds and more about integration, automation and staged modernisation of what already exists. ### Sources - [Characteristics of Australian Business](https://www.abs.gov.au/statistics/industry/technology-and-innovation/characteristics-australian-businesses) — ABS data on technology and cloud computing adoption among Australian employing businesses. - [Cloud Security Guidance](https://www.cyber.gov.au/resources-business-and-government/maintaining-devices-and-systems/cloud-security-guidance) — ACSC guidance on configuring and operating cloud services securely. *Cloud Engineering Explained* ## What cloud engineering covers Cloud engineering spans network architecture, identity and access, infrastructure-as-code, CI/CD pipelines, observability and cost control across AWS, Azure or Google Cloud. For a growing business, the work rarely starts from a blank slate. It starts with whatever is already running: an ERP, a CRM, an e-commerce platform, a handful of SaaS tools like Xero or HubSpot, and the scripts someone built years ago to make them talk to each other. A proper [cloud engineering Australia](/software-support/cloud-engineering/cloud-migration-services/) engagement usually spends more time mapping and rebuilding those connections than standing up new servers. A pattern that recurs across integration-heavy environments: the link between the finance system and the warehouse or logistics platform was built as a one-off point-to-point script, undocumented, and nobody currently on staff knows exactly what fields it reads or writes. Rebuilding that single connector as a proper, versioned API often takes longer than migrating the rest of the environment combined, simply because nobody can say with confidence what will break if it changes. ## Where it sits next to DevOps, SRE and platform engineering DevOps describes a culture of shared responsibility between development and operations, usually expressed through automated build and release pipelines. Site reliability engineering applies measurable reliability targets to that same software. Platform engineering goes a step further again, building the [internal developer platform](/systems-integration/) and self-service tooling that lets product teams deploy without needing deep cloud expertise themselves. Cloud engineering is the layer underneath all three: the infrastructure, networking and automation those practices operate on. Day-to-day, this shows up as ongoing [cloud infrastructure operations](/software-support/cloud-engineering/managed-cloud-services/) rather than a one-off build. *Questions buyers ask* ## Should we migrate to the cloud with a software engineering agency or a managed service provider? An engineering agency plans and carries out the migration. A managed service provider runs the estate afterwards. Many organisations use both, one after the other. Ask who owns the accounts and regions. Ask what you receive at the end: a target design, a cut-over plan and a tested rollback. Keep the infrastructure in accounts you control. ## What does a cloud migration involve? A migration runs in stages. First comes an inventory of what runs today. Then comes a target design. Then a cut-over plan and a rollback plan. Each stage ends with a decision that you make. *The operational problem* ## When cloud infrastructure starts holding growth back ### Problem Systems were connected incrementally over several years using whichever method was fastest at the time, so deployments are manual, nobody fully trusts the integrations between core platforms, and scaling any one part risks breaking another. **Common Pain Points** - **Undocumented integrations** Point-to-point scripts built years ago that nobody currently on staff fully understands. - **Manual deployment steps** Releases that depend on one person running commands in the right order, in the right environment. - **No visibility into failures** Integration or infrastructure faults discovered by customers or finance staff before anyone internally notices. - **Scaling fear** Hesitation to onboard new volume or a new sales channel because nobody is confident the current setup will hold. **Business Impact** - **Time Wasted** Recurring manual effort around every release and data reconciliation - **Cost Implication** Ongoing spend on duplicated infrastructure and repeated rework - **Opportunity Cost** Engineering time diverted into firefighting instead of building what the business actually needs next ### Solution A staged cloud engineering programme that documents and modernises the integration layer first, automates deployment and monitoring second, and defers any larger rebuild until the business genuinely needs it. **Our Approach** 1. **Map the real environment** *(Early phase)*: Document every system, integration and manual workaround currently in production, including the undocumented scripts nobody wants to touch. 2. **Replace the highest-risk connectors first** *(Staged, system by system)*: Rebuild the point-to-point integrations causing the most incidents or manual effort as versioned APIs, verified against live data before cutover. 3. **Automate deployment and observability** *(Ongoing)*: Introduce infrastructure-as-code and CI/CD pipelines so changes are repeatable and visible, rather than dependent on one person's memory. **Expected Outcome** A cloud environment that scales predictably, integrates cleanly with core finance and operations systems, and no longer depends on undocumented manual steps. *Key Takeaways* ## What matters most in cloud engineering - **Cloud engineering is the infrastructure and automation layer, not a product bought off a shelf** *Important* — It covers networking, identity, infrastructure-as-code, CI/CD pipelines and the APIs that connect cloud platforms to existing business systems such as Xero or Shopify. - **DevOps, SRE and platform engineering overlap but solve different problems** *Important* — DevOps is a culture of shared delivery responsibility, SRE focuses on measurable reliability, and platform engineering builds the self-service tooling teams use daily; cloud engineering underpins all three. - **Off-the-shelf cloud services usually beat custom-built infrastructure tooling** *Important* — Identity, monitoring, logging and CI/CD are mature managed services on AWS, Azure and Google Cloud; custom engineering effort is better spent on the integration layer that is actually specific to the business. - **Legacy modernisation works best staged around a business that keeps trading** *Critical* — Replacing one integration or service at a time, verified against live data, avoids the outages and budget blowouts a full-system rebuild typically risks introducing. Cloud engineering succeeds when infrastructure decisions, integration design and modernisation pace are matched to what the business actually needs to run reliably, not to a rebuild for its own sake. ## Cloud adoption and integration risk in Australia Public data on cloud adoption and security incidents, read alongside common integration failure patterns, frames where cloud engineering effort has the most impact for growing Australian businesses. - **Cloud service adoption: Mainstream among Australian businesses** — ABS business characteristics data shows cloud computing services have become standard for Australian employing businesses, with adoption increasing most among mid-sized and larger firms trading digitally. *Source: Australian Bureau of Statistics, Characteristics of Australian Business* - **Cloud misconfiguration incidents: Named in ACSC threat reporting** — The Australian Cyber Security Centre's annual threat reporting repeatedly identifies misconfigured cloud services among the contributing factors in incidents reported by Australian organisations. *Source: Australian Cyber Security Centre, Annual Cyber Threat Report* - **Point-to-point integration debt: Common in multi-system environments** (Estimate) — Businesses running separate finance, CRM and operations platforms frequently rely on undocumented point-to-point scripts built years earlier, which typically become the highest-risk and slowest part of any cloud migration. **Methodology:** Figures are drawn from published Australian Bureau of Statistics and Australian Cyber Security Centre reporting; qualitative points reflect recurring patterns observed across cloud integration and modernisation work. *Build, buy or modernise* ## Build vs buy: where off-the-shelf cloud tooling is enough Identity management, monitoring, logging and CI/CD are mature managed services on every major hyperscaler, and there is rarely a sound argument for building them from scratch. The genuine engineering effort belongs at the integration layer: the connectors between Xero, MYOB, Shopify, HubSpot and whatever custom or legacy platform runs the operational core. That is where off-the-shelf tools fall short and where [application modernisation strategy](/software-support/cloud-engineering/cloud-migration-services/) actually pays off, because nobody else sells a product that understands a specific business's data and workflow exceptions. ## Staged modernisation over a full rebuild A full-system rebuild is tempting when a legacy platform feels unmanageable, but it concentrates risk into a single cutover and usually takes longer than planned. A staged approach, often following a strangler pattern, replaces one service or integration at a time and verifies it against live data before retiring the old path. This is the approach behind [staged modernisation](/software-support/legacy-modernisation/): the business keeps trading throughout, and each stage can be judged on its own evidence rather than on a single high-stakes go-live date. API-first design, documented with a standard such as OpenAPI, makes each stage easier to test in isolation and easier to hand to a future team without re-discovering how it works. ## What managed hosting and support costs a month National Digital manages the hosting, backups, monitoring and security patching of a system in the client's own cloud or hosting account, and sets a response time for a fault. National Digital does not supply the hosting itself, and hosting plan fees stay with the provider. Priced per month at the 1-day Product Support retainer tier. ### Hosting and monitoring The environment the system runs in, the backups behind it and the checks that show when something changes. - **Managing hosting and backups in your own account** — $374/month: National Digital manages the production environment in the client's own cloud or hosting account, with scheduled backups and restore checks. The provider bills the hosting plan. - **Monitoring and alerting** — $374/month: Uptime and error monitoring with alerts that reach a named person. ### Patching and response Security updates applied on a schedule and a named response time for a fault. - **Security patching** — $374/month: Operating system, framework and dependency updates applied and checked on a schedule. - **Response time and fault handling** — $373/month: A stated response time for a fault in production, and the triage that follows it. **Total Fixed Fee:** $1,495 **Payment Terms:** Invoiced monthly in advance, ex GST, from the month the handover to National Digital is signed. ### Key Assumptions - One production system and one environment for it. A second system is priced separately. - The four lines split the 1-day tier evenly and carry no separate price; the month is one fee. - Engineering hours for fixes and new work are not included. They come under a Product Support retainer. - Hosting plan fees, third-party licences and cloud usage belong to the client and are billed by the provider.

National Digital reviews the integration and infrastructure layer first, then recommends a staged path rather than a rebuild by default. ## Cloud engineering questions we hear often ### What's the real difference between platform engineering and DevOps? DevOps is a set of practices and culture where development and operations share responsibility for releasing and running software. Platform engineering goes further, building a self-service internal platform so product teams can deploy and operate services without deep cloud expertise. Cloud engineering supplies the infrastructure, networking and automation both rely on. ### How much does managed cloud support cost in Australia? Managed hosting and support for a system in production costs $1,495 a month, ex GST. National Digital does not supply the hosting, and hosting plan fees stay with the provider. Engineering hours on top come under a Product Support retainer. ### Is cloud engineering the same thing as cloud computing? Not quite. Cloud computing refers to the on-demand infrastructure and services providers like AWS, Azure and Google Cloud offer. Cloud engineering is the discipline of designing, automating and operating systems that use that infrastructure well: network architecture, identity, deployment pipelines, cost control and the integrations connecting it to existing business systems. ### What does an API-first approach to development actually mean? It means designing the interface a system exposes before building the system itself, usually documented with a standard such as OpenAPI (Swagger), so other applications or teams can integrate against a stable contract. For businesses running Xero, HubSpot or a custom ERP alongside each other, this reduces the brittle point-to-point scripts that typically break first when one system changes. ### When does it make sense to modernise a legacy system rather than replace it? When the system still does its core job correctly and the real pain sits in specific areas such as reporting, integration or scaling. A staged approach, often using a strangler pattern to replace one service or connector at a time, keeps the business trading while reducing risk compared with a full rebuild, which more often blows out in cost and timeframe than it succeeds on schedule. ### Where do cloud engineering and cybersecurity responsibilities overlap? Cloud engineers typically own network segmentation, identity and access configuration, and infrastructure-as-code templates, all of which directly affect security posture. The Australian Cyber Security Centre has repeatedly flagged misconfigured cloud services as a recurring factor in reported incidents, which is why security review is usually built into the engineering pipeline rather than treated as a later, separate step. ### What tools do Australian cloud engineering teams typically rely on? Most teams combine a hyperscaler such as AWS, Azure or Google Cloud with infrastructure-as-code tools like Terraform, container orchestration where scale justifies it, and CI/CD platforms such as GitHub Actions or GitLab. Around that sits observability tooling and the APIs connecting the cloud environment to line-of-business platforms such as Xero, MYOB or HubSpot. ## In this hub · every guide - [Application performance optimisation agency Australia](/software-support/cloud-engineering/application-performance-optimisation/) — 9 min - [Database optimisation for Australian latency](/software-support/cloud-engineering/database-optimisation/) — 9 min - [Code optimisation for legacy applications](/software-support/cloud-engineering/code-optimisation/) — 9 min - [Performance testing for Australian users](/software-support/cloud-engineering/performance-testing/) — 8 min - [Cloud Service Providers](/software-support/cloud-engineering/cloud-service-providers/) — 9 min - [Managed Cloud Services](/software-support/cloud-engineering/managed-cloud-services/) — 9 min - [Migrating a Live Platform to the Cloud Without a Big-Bang Cutover](/software-support/cloud-engineering/cloud-migration-services/) — 9 min ## Related **Parent:** - [Software support and modernisation for Australian businesses](/okf/software-support.md) **Children:** - [Application performance optimisation agency Australia](/okf/software-support/cloud-engineering/application-performance-optimisation.md) - [Migrating a Live Platform to the Cloud Without a Big-Bang Cutover](/okf/software-support/cloud-engineering/cloud-migration-services.md) - [Cloud Service Providers](/okf/software-support/cloud-engineering/cloud-service-providers.md) - [Code optimisation for legacy applications](/okf/software-support/cloud-engineering/code-optimisation.md) - [Database optimisation for Australian latency](/okf/software-support/cloud-engineering/database-optimisation.md) - [Managed Cloud Services](/okf/software-support/cloud-engineering/managed-cloud-services.md) - [Performance testing for Australian users](/okf/software-support/cloud-engineering/performance-testing.md) # Citations 1.
