Picking a Shared or Dedicated Exchange Server
Posted by Exchange Hosting Reviews as Help Center
There is no clear cut way to say if you need a shared or dedicated exchange server, but here are some helpful points to consider. Starting with a shared server is not a bad option. It is important to find out the ease of transition from shared to dedicated if you do find yourself needing more resources. Below are the evaluations of a few main points for both shared and dedicated Exchange servers.
- Number of users
- Mailbox size flexibility
- Bandwidth demands
- Server uptimes
- Contractual Agreements
- Administrative control level
Shared Exchange Server:
Cost effective general Microsoft Exchange access. Suitable for most small to medium businesses.
- Suitable for small to medium businesses. Server would also be shared with many other small to medium businesses.
- Mailbox sizes are governed solely by the plan details chosen. Flexibility is limited but may be more then suitable for your needs.
- Based on the terms of your plan, bandwidth could be capped and may be set at a flat rate for overages.
- Uptimes for shared servers are generally 99.5% to 99.9%. Although reasonable, sharing resources with other companies makes you susceptible to outages.
- Shared servers generally offer flexible contract free agreements.
- Very little to no control is given to a shared server plan. Administration is handled by the provider on their terms and conditions.
Dedicated Exchange Server:
Pricey highly configurable access to Microsoft Exchange for the advanced user or the larger company.
- You control the number of mailboxes being used since you are on a server alone.
- Allotment of mailbox sizes can be adjusted by you and the server will only contain your mailboxes.
- Bandwidth allotment is generally greater but may also be capped. An overage rate can apply for dedicated servers.
- With the server being dedicated solely to your business, a 100% uptime is almost a certainty.
- Since additional hardware is required for a dedicated server on the providers side, usually a 1 year contract is required.
- Dedicated servers allow control over permissions, groups, rules, and access. Some Exchange users do not need this extra administration, but in many cases it can be quite useful.
