Office 365 vs VMhosts Private Hosted Exchange


Office 365 is an excellent solution for small and large businesses. It isn’t suitable for everyone though. Our VMhosts Private Hosted Exchange Solutions provide additional control and flexibility.

By leveraging the cloud to deploy a private hosted exchange the company is able to maintain control of their Exchange infrastructure.

One of the main benefits of deploying a private hosted exchange solution over an Office 365 solution is technology exposure. Many IT admins are encouraged to keep up to date and current with software applications such as Exchange. By deploying a private hosted exchange, you have the ability to stay in control of the setup and configuration with the added bonus of keeping your CV up to date! But don’t worry, we also offer many levels of managed support from full pro-active to reactive support for when you need that extra level of support.

VMhosts Private Hosted Exchange Solutions have many advantages over a Microsoft Office 365 multi-tenanted services including;



Office 365

Using dedicated secure SSL VPN/Firewalls we can extend your existing Active Directory infrastructure to our cloud infrastructure. Using a dedicated exchange server the customer will maintain FULL control over the environment but still benefit from per user per month licensing.

As a minimum we recommend deploying a single Exchange 2013 Standard server which will host both the Client Access roles and Mailbox roles. Our infrastructure has been designed on top of enterprise grade hardware and clustered storage technology. Our HA features ensure your servers benefit from the maximum amount of uptime at all times.

We recommend at least 2 x vCPU cores and 8GB or Memory for Exchange 2013 depending on the number of mailbox users. Due to the nature of this solution, we are able to scale resource up or down as required. This enables the customer to only pay for the resource that is actually required rather than paying for over committed resource.

Granular user and shared mailbox quotas settings allows your Administrators to maintain full control. Just as with all or resources Disk space can be added as and when required.

Database Availability Groups (DAG)

In addition to the high availability built into our cloud, you are also able to benefit from the extra level of protection a DAG can provide. We have high speed layer 2 interconnects between our datacentres meaning that you can protect your environment against an entire datacentre failure by using this extra layer of protection. We will deploy two (or more) Exchange servers across multiple datacentres meaning that even should the worst happed, recovery of systems is quick painless and handled by us!


Domain Controller and IPSEC VPN

VMhosts Private Hosted Exchange Solutions as an added extra benefit, providing an offsite hosted replica of our Active Directory.

Using a dedicated VPN appliance a secure site to site IPsec VPN tunnel will be established. Using Active Directory Sites and Services, a new Active Directory site will be configured using a dedicated domain controller which will be part of our Forest and Domain structure.
