Plone Deployment WPD2009

Plone Deployment Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 1

Introduction • Different scenarios – Different page types – Page composition • Hard to estimate – Many variables: hardware, bandwidth, ... – Multiple benchmarks Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 2

Zope • Is the application server • It does the low level management • It is completely integrated Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 3

Vanilla Plone + Apache Internet • “Classic” • Practical (ports, statistics, etc.) Webserver • Conﬁguration – Virtualhost – Advanced solutions – etc. Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 4

Vanilla Plone + Apache • Yes, if • No, if – Few, well – Multicore server distributed – Stable contents contents – Hi concurrency – Limited users levels – For development Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 5

Plone + Varnish + Apache Internet • Reduced response time • More user load Webserver • Lower machine Cache Sys load Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 6

Plone + Varnish + Apache • Yes, if • No, if – Stable contents – Multicore server – Limited server – Development resources – High number of – ... in general the users suggested – High number of deployment editors Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 7

Architecture on multicore server Internet Webserver Cache Sys Load Balancer Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 8

Architecture on multicore server • Yes, if • Maybe not if – Multicore (>2) – Variable user load – Hi number of users – Pages composed by a high number of sources Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 9

Distributed Architecture Internet s2 Webserver Cache Sys s3 Load Balancer s1 s4 s5 Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 10

Distributed Architecture: pros • Dynamic System – Only the necessary servers are turned on • Fault tollerance – Zope/Plone servers are redundant – ZEO can be “distributed” • Maintenance similar to that of a single instance – Backup, updates... Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 11

With Relstorage Internet s2 Webserver Oracle / Postgres s3 Cache Sys Load Balancer s1 s4 Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 12

Relstorage: pros DBMS Support: - Backup and restore - Redundancy and fault tolerance - Authenticated access to the DB data - Tools of the chosen DBMS - Speed improvements* Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 13

Distributed Architecture: when? Always if possible. Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 14

Plone in the Cloud • Amazon Web Services (AWS) – EC2: Elastic Cloud Computing – S3: Simple Storage Service in practice: a solution for hosting based on virtual servers (XEN) following the principle: "pay only for what you use, as you use it”. Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 15

Plone on Cloud II • Immediate startup – To start working with EC2 (<15 min) – To start a new server (<1 min) • Complete autonomy of management – Turn on a new server when needed – Turn off a server if not needed – Different machine options Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 16

Plone on Cloud III Back to Plone again: It’s possible then to activate or turn off an arbitrary number of instances cloning the same server, implementing a dynamic farm. In particular on AWS: •Elastic load balancing •Autoscaling Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 17

Case1: Logcluster • www.logcluster.org • 3 Zope/Plone + ZEO • Daily updates • 20k requests a day Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 18

Case2: EOL • www.eol.ucar.edu • 5 Zope/Plone + ZEO • 2k pages a day • 32k pages in the ﬁrst month Thanks to Kelly Craig for the material for this case study. Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 19

Questions? Data on performances and different setups available on request federico.guizzardi@reﬂab.com Plone Conference 2009 – Federico C. Guizzardi – 21 Aprile 2009 20
