A seamless partnership

● Nextcloud - an awesome partner● working together seamlessly and regularly● Product support & Professional Services.

● A single support partner.● Nextcloud have experts in Collabora Online

● No blame-game nightmares:● Bank: 5 people & 5 companies in the room.

– It is exactly not like that … with us

● Single point of contact, and relationship.● A great time in FLOSS history.


Collabora Online Vision:

Full-feature, Open Source,

On-premise / hosted – control your data & apps ...

No compromises & flexible

Partner driven: complementing Nextcloud’s vision

MS Office Online browser a stop-gap ...



Full-feature … what does it mean ? ...

The things the feature matrix hides ...

The complete set of pre-canned border functionalityin MS Online

The rich border UI in Collabora Online



100% Interoperability & Collaboration

Interoperability & feature richness –key deliverables ...

● We have very powerful document interoperability

● Collabora Office → ~8 million LOC, MS Office ~30 million LOC

● The most mature Office code-base outside of Microsoft

“100% interoperability” - not a credible claim

● I was on the ECMA Technical Committee standardizing MS’ XML formats.

● Interoperability – a mix of: import, rendering, feature-set, export

● To edit you have to understand the format – no reliable short-cuts.

Expectation here – we can win !

● Doing better than Google Docs, and Microsoft Online

● Collaboration is the key driver ...



Example: writer Rich Fields support ...

Fill out DOC / DOCX forms

● tab through editable fields; skip protected sections

Responsive Browser based integration

● Leverage the server for large /complex document rendering

● Fast pan / zoom / selection etc.

Not limited by power of device / JS

● Server can load large documents

● Server side font rendering

● Secure: Document Data stays on servertransmitted as pixels.

● Tile watermarking

Blending Mobility with Rendering power

Hardware Sizing

Guidelines:

● 10 active users / CPU thread

● 50Mb RAM / active user

● 100kbit/s / active user

5000 ‘users’ → diversity → 500 concurrent users:

● 50 CPU threads

● 25 Gb of RAM

● 50 Mbit of bandwidth

Ultimately: CPU threads & network become

cheaper over time.

HA / setup example ...

Split 5k users into three 8 CPU machines, 8GB each

UsersHA balancer of

choice: ha-proxy, or F5

Key attribute is to ensure that all traffic related to the same document goes to the same worker – all collaborators end up in the same address space. Balancing on WOPISrc
