I wanted to respond to an earlier message . . . and for the record, anyone who is being reasonable will see that this is a tremendously biased message and is not a useful comparison. Just think! The majority of businesses in the world have been snowed and have bought an inferior product! (According to Gartner, IDC, and Radicati).
See my responses in Bold.
This isn't biased, those are plain facts. If you're going to accuse the authors of bias, at least detail your reasons for saying so, thereby giving them an opportunity to reply.
I'm a Domino Admin of 13 years experience and I admit I don;t know much about Exchange, and so I would love to hear some reasons from Exchange admins on why they think Exchange is better. Even on a purely email vs email platform, if that's what they'd prefer.
Here's some things I have heard about Exchange so feel free to rebuke if you can:
The jet-based data store is not designed to grow into the hundreds of gigs as commonly seen in modern corporate email systems. As a result, there are only two kinds of Exchange Administrators - the kind who have experienced data loss and the kind who soon will. I am sorry, but in todays corporate environment where compliance is often very important, you cannot afford to base your email system on a server that has such a reputation of being this unreliable.
I've worked on databases as far back as Exchange 5.5 that were over 100GB, but what you're missing from your knowledge is that in Exchange you can have MANY databases (20+) all of which can be over 100GB if you need them to be (but who wants to take the time to backup and restore a 100GB file?). Honestly, if you need to have more than 1TB on one server, don't you think you'd have two servers? Corruption? Data loss? If your domino database is sitting on a disk that is not mirrored and you don't have it replicated anywhere and the disk dies, does Domino magically bring the data back? No. just like Exchange, Domino is only as good as the design and implementation. If you don't know what you're doing and make a bad design the result will suck. End of story.
We all know that Outlook/Exchange is far more prone to virus attacks than Notes/Domino. Apparently Exchange has more flexible anti-spam controls but Domino has good enough, and if you use a service such as messagelabs or mailcontrol you don't need that anyway.
I've never had a customer infected with an email-borne virus on Outlook. Ever. I know that it happens, but since we're not talking about actual facts and figures here, there's my anecdotal evidence. For the record i also recommend using MessageLabs or Frontbridge, or Postini, or any of those external services.
You have to take the server off-line to backup the data store. I wouldn;t have thought this was true with open file backup clients so can someone tell me?
Are you kidding me? I've been working on Exchange since 5.5 and NEVER have you had to take the server off-line to do a backup! Even free NT-Backup can backup your exchange stores on-line.
In my current job, we have a target of 99.9% server uptime during production hours - not including any scheduled maintenance/upgrades. I am sure that would be impossible to meet under Exchange but we do it easily. We cover Australia and New Zealand which includes several time zones so production hours is 13 hours per day. That allows for about 4 minutes downtime per server per week.
Again, the "i am sure that would be impossible to meet under Exchange" shows how biased you are. You have no idea. No enterprise messaging platform would survive in today's marketplace if you couldn't maintain a VERY high level of uptime. Exchange can give you all the nines you want. Most of our customers sit at 100% for the year, and none of them are below 99.9. Honestly many companies are looking at 4 or 5 nines. Exchange is a highly stable product when installed on stable hardware.
To my knowledge, the one thing MS does better, other than marketing, is integration, especially if your company is using microsoft desktops. Having the lions share of the market, 3rd party applications such as document management systems tend to build their integration into Exchange first and Domino is done almost as an afterthought. Having said that, if you are a SAP house do some reading on an upcoming product called Atlantic.
The bottom line is that Exchange is extremely viable in the messaging space, and so is Domino! Domino provides excellent business process and development that can be harnessed into an incredibly powerful money-saving engine! However in order to do it right you need to spend some bucks. If you're going to compare nothing but Exchange and Domino, Exchange is MUCH cheaper. However if you want to talk all the Bus Dev apps then you're on much more equal footing on a cost standpoint. I do hear that Notes 8 is going to be awesome! If you guys are really interested in being a shop that does real "comparisons" then make sure to put some effort into understanding both products. It is clear that whoever wrote this doesn't know anything about Exchange. And no, installing it a couple of times in the lab doesn't quite count as "knowing" it.
