Re: [PLUG] question on system
Unless you have a small(er) percentage of those 500 users doing webmail, I suspect that a single box would not be sufficient. This probably applies to any web-based dynamic content. Anything static is trivial to serve in quantity. Also, because its dynamic, you can’t particularly make good use of caching. If you won’t have very many people accessing web stuff, or web-based stuff (php, for example), then a single box is more than sufficient. To provide some perspective, using next-cloud (like owncloud, php/web based file sync), a single user is able to eat several cores with php processes doing file manipulations (copy/move/etc). The bigger the files, the longer they eat cpu. Strongly recommend you do some testing to determine how your use case will behave. > On Sep 21, 2018, at 8:17 PM, Ben Koenig wrote: > > Nevermind.

Re: [PLUG] question on system
Email is perhaps the easiest one. A single modern server running postfix/dovecot can easily handle the mail for those users. Assuming you will do some SSO using something like ldap/postgres, there are appropriate connectors and config knobs. If you want everybody to use webmail, then you’ll probably need another 1 or 2 web frontends (depending on how many people will be online at the same time). If you want to do testing, postfix comes with a couple of tools called smtp-source and smtp-sink. The former will generate email, the latter will cause it to disappear. You can run them on their own nodes and pass the mail through your postfix server. I suspect that you will find postfix able to handle thousands of messages per second w/o breaking a sweat. If you really will be doing thousands of messages per second, you will likely need a small farm of boxes to run spam-assassin and your database. Neither will handle the throughput that postfix is capable of. If you do this, make sure you utilize the spamd/spamc functionality, it greatly improves the performance, bringing it almost up to tolerable. > On Sep 21, 2018, at 6:42 PM, Ben Koenig wrote: > > Let's assume I'm an aspiring Google IT guy and I'm preparing for an > interview as a Google System Adminstrator. > > If I want to build a server that can handle emails from 800 users (500 with > some headroom) what would I need?

Let's assume I'm an aspiring Google IT guy and I'm preparing for an interview as a Google System Adminstrator. If I want to build a server that can handle emails from 800 users (500 with some headroom) what would I need? Assume that my internet connection is capable. What kind of CPU do I need to process 800 incoming and outgoing emails in a given moment?

Re: [PLUG] question on system
When looking at the requirements 200-500 users - I cannot imagine any practically useful scenario without single sign on solution al least across the web services and centralized group/access control. With 200-500 users there would be fair amount of user and access management workload. This needs to be distributed to data owners/managers/leaders. That is beside the already mentioned associated storage, backup, security and disaster recovery management. There are other companies beside G-company providing these kind of services or enterprise level support. Some examples: Kolab, Nextcloud, Collabora, ... Regardless of solution chosen - someone has to manage it full time. Given the number of users - it is critical - hence it needs more than one individual to cover for vacation/sickness/disasters/etc. Just adding to the list of consideration. Do look up the services mentioned above though. They work like G-company, but they are OSS, and the platforms are deployable and manageable by individuals - so the lock-in is not as strong as with proprietary services.

Re: [PLUG] question on system
It's been several years since I looked into this... Like others have said, the administrative overhead is substantial, and I ultimately decided that it was just easier and more reliable (for my needs) to use Google. That said... The top product I was looking at at the time was Kolab, http://kolab.org, and it SEEMS to meet many of your requirements... I consider it unlikely that a company of this size would be served by any single application... If I were setting up Kolab for a client, a good amount of energy would have to be put into questions like "How do we manage users?" And "How do we manage storage?" And "How do we manage backups?" Like, maybe you will find that managing lots of users pushes you into needing an LDAP server, possibly with Single Signon. As you add these "Supporting" services, your security footprint increases, and you may need additional firewall and intrusion detection software; Maybe these services should be on "Bastion Servers," individual servers for each service to increase both performance and security... Maybe you virtualized some. Maybe those questions lead to non-Linux answers... Maybe you find managing the workstations of all those users works best with ActiveDirectory rather than OpenLDAP; Maybe you find that managing the storage requires something more robust than LVM on XFS or EXT4... And then is Kolab's file sharing (WebDAV, if I remember correctly) enough for your users? Adding SMB and NFS can have unintended complications. And all of those questions have to be balanced against the inherent feature creep that comes from wandering down this road. For many companies, the answer is to simply let Someone Else do it... Often, that Someone Else is Google.

Re: [PLUG] question on system
What kind of budget is allocated for this? Managing a system for 250-500 users is non-trivial. Scaling a solution for this will have non-trivial hardware/network costs associated unless there are some significant limitations placed on how many people can access at a time, and/or what size files are allowed to be shared. Somebody asked something somewhat similar recently. Freedom box does all these things, but you would need to test and potentially scale the components independently, making the work much more involved than effectively dealing with a soft-appliance. > On Sep 19, 2018, at 3:39 PM, logical american > wrote: > > Hello again: > > Can anyone suggest a linux system server which will successfully do the > following? > > 1. successfully imitate and replace the Google Groups program > 2. successfully imitate and replace the Google gmail server > 3. allow Google drive operations or simulate those operations > > I am seeking to move a large group of users (200-500) from Google Groups and > gmail over to a stand-alone server and provide some type of Google drive > functionality also for them, but at a bare minimum a common area to download > files must exist so users can store their files. > > What would you suggest? > > The users are in the public domain. > > Thanks for the input > > - Randall > > ___ > PLUG mailing list > PLUG@pdxlinux.org > http://lists.pdxlinux.org/mailman/listinfo/plug -- Louis Kowolowskilou...@cryptomonkeys.org Cryptomonkeys: http://www.cryptomonkeys.com/ Making life more interesting for people since 1977 ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug

[PLUG] question on system
Hello again: Can anyone suggest a linux system server which will successfully do the following? 1. successfully imitate and replace the Google Groups program 2. successfully imitate and replace the Google gmail server 3. allow Google drive operations or simulate those operations I am seeking to move a large group of users (200-500) from Google Groups and gmail over to a stand-alone server and provide some type of Google drive functionality also for them, but at a bare minimum a common area to download files must exist so users can store their files. What would you suggest? The users are in the public domain. Thanks for the input - Randall ___ PLUG mailing list PLUG@pdxlinux.org http://lists.pdxlinux.org/mailman/listinfo/plug
