Designed from the ground up – AOD for Greentree ideally suited for cloud hosting performance sensitive, business-critical systems


AOD Greentree


Unrivalled accessibility

  • Rather than simply hosting data, AOD Apps moves the entire Greentree application environment into the cloud, enabling it to be accessed from almost any type of Internet connected device and perform faster.
  • This allows staff that use Mac, iPad and Android tablets to use the full functionality of their Greentree applications in the exact same way as they would from a Windows computer, giving you unrivalled accessibility
  • AOD’s cloud infrastructure is built from the ground up to provide a dependable and reliable cloud hosting platform for business-critical applications and servers.
  • Throughout its history, AOD has always been solely focused on the cloud hosting of performance sensitive, high-value systems. This continual focus is evident in all aspects of AOD’s infrastructure and differentiates AOD from other cloud providers.

Internet Connectivity

  • AOD’s facilities  are equipped with top-tier backbone internet access across multiple providers to ensure the highest levels of reliability and fastest performance.
  • Thanks to special arrangements and configurations, AOD traffic for New Zealand customers travels over the fastest Australia-to-New Zealand link. This connection operates at a network response time of less than 20 milliseconds, resulting in total network response times below 75 milliseconds for most New Zealand locations.
  • An additional direct link to Australia’s premier internet exchange – IX Australia – gives AOD a direct connection to hundreds of Australian ISPs such as iiNet, TPG, Amcom, Exetel, Pacific Internet and many more.



Internal Networking

  • All of AOD’s systems are linked via highly reliable and extremely fast 10Gb networking. Additionally, years of optimisation at every level of the network ensure maximum LAN performance.
  • As a result, data-intensive operations between applications such as Excel and Greentree data sources perform extremely well.

Compute Systems

  • As a key component of any cloud infrastructure, AOD’s virtualisation host servers are sourced exclusively from Tier-1 hardware providers and are carefully designed for maximum reliability. All servers are equipped with redundant connectivity to essentials such as power, storage, networking, etc.
  • In addition servers undergo an aggressive replacement lifecycle and are monitored carefully to predict and circumvent outages due to hardware failure. Server upgrades and replacements occur with no outages to AOD customers. 
  • AOD’s virtualisation environment is based on the Enterprise Plus edition of the VMware hypervisor and cloud management stack.
  • To allow AOD to respond to changes in demand quickly, individual AOD systems can be assigned additional RAM, CPU and storage resources without requiring any downtime or reboots


storage nodes

Storage Systems

  • The performance and reliability of any computing environment is deeply dependent on the underlying storage systems. Database-centric systems in particular are heavily reliant on the storage architecture for fast and consistent performance.
  • AOD has been designed and optimised specifically for cloud hosting database-centric applications, offering industry-leading storage and thus database application performance. With approximately 100 performance sensitive and mission-critical databases operating within it, AOD is a tested and proven environment for even the most intensive database applications.
  • This outstanding performance is achieved through using advanced systems and techniques that go far beyond even Solid State Disk (SSD) technologies.


  • AOD provides managed security services covering below-OS antivirus and malware protection and extensive network security.
  • Antivirus and anti-malware software which operates below the Operating System can detect and prevent infections which software installed on top of an Operating System simply cannot.
  • Combined with the firewalling and intrusion detection/prevention systems which continually monitor, log and control access to AOD, customer systems and data are kept safe and well protected.



Monitoring and Security

  • AOD is a full-service platform; the AOD team continually monitor and respond to changes to the system, meaning no actions have to be taken by partners or customers to make sure their systems continue to work smoothly.
  • To achieve this pro-active operation, AOD incorporates an extensive monitoring platform which tracks a large range of services and performance metrics within the system to ensure smooth operations and to detect issues before they are noticed by customers.
  • Access to this monitoring platform can be arranged for select partners to provide extra visibility into their customer’s systems and operations. This historical visibility of performance and usage-centric metrics allows AOD customers to track and correlate utilisation changes with changes to the business. Additionally, performance metrics are automatically compared with previous weeks to highlight unusual events or activity.

Managed Backup Services

  • AOD customer’s systems and data is protected using AOD’s managed backup service. This service is designed to provide fast and reliable backups of large amounts of data without impacting the performance of the systems.
  • The managed backup service is configured to comprehensively protect all of the customer’s data.
  • Thanks to its thoroughly modern architecture, entire sets of customer data comprising hundreds of gigabytes of data can be backed up frequently, with minimal impact on the customer VMs performance and response times.
  • Because each backup is a full and complete backup of the protected systems, customer systems can be restored from any desired backup in their entirety. There is no need for the typical slow and error-prone layered processes of restoring the latest full data set and finally the latest incremental data set.
  • Unlike many cloud backup solutions, AOD’s managed backup service is optimised to provide effective off-site backup data protection as well as fast recovery from accidental deletion or software corruptions. This is made possible through the use of two independent backup storage repositories – one optimised for on-site fast recovery and one for off-site data protection.



Scenario – Accidental Deletion

  • In the event of an accidental deletion of important files or databases within the customer’s systems, data can be restored directly into the running system without the time delay of retrieving off-site backup data.
  • The ‘Fast Restore’ backup repository’s performance allows even large files and databases to be restored very quickly. This can significantly minimise the business impact of a misconfiguration or accidental deletion.

Scenario – System Corruption

  • In the event of a system corruption or unrecoverable misconfiguration, an entire VM can be restored and either replace or run along side the corrupted original.
  • Even with fast-performing backup repositories, restoring large 500GB VMs can be a time consuming process. If the corruption or misconfiguration occurred during peak operating hours, this still results in a large outage period with significant business impact.
  • To address this scenario, the AOD managed backup service incorporates a powerful instant-restore capability, allowing the failed VM to be run directly off the backup repository. This means even a very large failed VM can be up and running in minutes rather than hours. At a suitable time, the VM can then be migrated back into the primary storage environment.
