Redundant Exchange Environment
Hosting.ca has deployed a load balanced Exchange 2010, 2016 and 2019 clusters allowing for maximum up-time for our customers. As shown in the following image below, we have taken the extra step and added a secondary Exchange server in case an entire failure would occur. In fact, all of the required Exchange servers have been duplicated to avoid any downtime. We have deployed many DAG groups to maximize up-time. As well as utilizing load balancers to ensure equal distribution among the redundant exchange environment.
Your typical exchange environment would only include 1 Mailbox Server, 1 Active Directory, 1 Client Access Server, and 1 Hub Exchange Server. Hosting.ca has duplicate servers. Other providers may be using another type of clustering system with shared storage. If that storage becomes corrupt or fail, your email will not be accessible. Hosting.ca is different. We do NOT use shared storage. This is a key factor in why our services are more expensive.
In addition to the normal Exchange services we offer, we have also installed a cluster of Barracuda Spam Server appliances as well as redundant SpamTitan Spam Appliances. This assists us in up to the minute spam protection by Barracuda Networks and SpamTitan Anti Spam services. Please see the Barracuda details page for more services that it provides.
Redundant Exchange
Key benefits of load balancing. Here are a few key benefits:
- Ensures the application is always available
- Provides a stable, optimal performance
- Ability to isolate servers which reduces risk when performing upgrades/maintenance
- Scalability
We can turn off servers live and perform updates while customers are still connected to our systems.
