IT Infrastructure and Cloud Services Sydney for businesses of 15 to 70 staff

Planning, building and managing the systems a business runs on: servers, networks, storage, devices, cloud platforms and licences. For a business of 15 to 70 staff, the work usually covers Microsoft 365, Azure, the office network and any servers still on site.

It depends on what you run. Microsoft 365 is a per-user monthly subscription. Azure is billed on what you consume, so servers and storage cost more as they grow. Project work, such as a migration, is quoted separately. Elscomm gives a fixed quote after a free assessment, including an estimate of the monthly running cost.

Elscomm is a managed service provider based in North Sydney (business address: Level 25, 100 Mount Street), planning and managing infrastructure for Sydney businesses of 15 to 70 staff since 2006. We work cloud-first on Microsoft Azure and Microsoft 365.

Cloud services are the platforms themselves, such as Microsoft 365 and Azure. Managed cloud services add a provider who sets them up, monitors and patches them, controls costs and plans what comes next.

Many businesses of 15 to 70 staff no longer need one, because email and files run in Microsoft 365. A server still makes sense for some line-of-business software, very large files or equipment needing a local connection. If yours runs Windows Server 2016, Microsoft ends extended support on 12 January 2027, so plan its replacement now.

It depends on the system. Cloud spreads the cost into monthly fees. On-premises puts it upfront, and the true cost includes power, backups, support and replacing the hardware every few years. Compare the two over the full life of the system, not the first year.

For a tenant provisioned in Australia, Microsoft stores core Microsoft 365 customer data at rest within Australia, including Exchange Online mailbox content and SharePoint Online site content. This extends to Teams chats and channel conversations and files uploaded to OneDrive for Business. For Azure, you choose the region. Microsoft lists Australia East in New South Wales, Australia Southeast in Victoria, and Australia Central and Central 2 in Canberra. We build in an Australian region unless you have a reason to go elsewhere.

Microsoft secures its data centres and the platform. Your business remains responsible for who has access: accounts, passwords, devices and permissions. Multi-factor authentication, secure Microsoft 365 settings and a separate backup cover your side. Microsoft 365 retention settings and recycle bins do not replace a backup.

A staged move keeps disruption low. We test with a small group first, move one system at a time on agreed dates, keep a rollback plan for each step, and tell staff what changes before it happens.

Hybrid means running some systems in the cloud and some on site, connected together. It suits businesses moving in stages, or keeping one system local while everything else runs in Microsoft 365 and Azure.

Infrastructure as a service (IaaS) means renting servers, storage and networking in a platform like Azure instead of owning the hardware. Managed cloud services add a provider who runs those resources for you, from monitoring and patching to cost control.
