You won’t believe, but it all started with a laser printer

The story started In the late 1970s, with Richard M. Stallman
(RMS), a staff programmer at MIT.

We like to call it “RMS and the printer”

8. (2) Cloud Computing

Where Literally, any thing can be as a service

9. (2) Cloud Computing
●
I believe this time should be “Open Source” Golden age
●
We can integrate lots of “Open Source” solutions together and create a
strong “Open Source as a Service” where we have all the tools starting
from a simple “vi” editor until “Openstack cloud management service”.

10. (3) LibreOffice Online – Nextcloud
One nice example if we are talking about Open Source in the Cloud
era could be the awesome mix between two giant open source
projects:
●
LibreOffice Online
●
Nextcloud

11. Continued
The goal, LibreOffice Online – Nextcloud integrated together
(3) LibreOffice Online – Nextcloud

12. ●
LibreOffice Online
LibreOffice Online is a server service built
from the main LibreOffice project code
which provides display and collaborative
visual editing of a range of document types.
To be fully functional, it has to be integrated
with file access and authentication.
For anything more than casual use, we need
to consider load balancing and other scaling.
Key features are collaborative editing and
excellent office file format support.
●
Nextcloud
Nextcloud is an open source, self-hosted
file share and communication platform.
Access & sync your files, contacts,
calendars & communicate and collaborate
Continued
(3) LibreOffice Online – Nextcloud

13. Integrating LibreOffice Online and Nextcloud both together, creates a competitor to
the “Google drive+docs”, Dropbox, Microsoft Office 360, etc.
BUT, yet FREE and Controlled by user..
For example:
●
Every single service process is monitored by user.
●
Data is stored in user’s own servers & storage units
●
Security of the service is controlled and customized by the user
Continued
(3) LibreOffice Online – Nextcloud

14. First, we’ll need to Install and configure Collabora in our server (either local or remote).
●
And We have two methods for achieving that:
→ LibreOffice online Docker image
→ LibreOffice online from binaries
Ex: Collabora Online Development Edition (CODE), Kopano packages
it needs some extra work efforts to install,
configure,etc.

$ docker pull libreoffice/code

15. Continued
Now, we need to install Nextcloud server:
●
Well, its a PHP website, so simply we need to do the following:
→ Install and configure apache (httpd server)
→ Prepare database with database user to give to give to our Nextcloud server
→ Download Nextcloud website compressed file
→ Extract the compressed file contents to the right place of apache websites
directory.
→ For the first time only, we open it from browser then we will give it the
user, password and database to be used
●
Now we have Nextcloud installed
