PowerPoint Presentation
- 1. Alfresco on AWSEC2 Provisioning and deploying Alfresco solutions on Amazon Web Services
- 2. Advantages Of TheCloud
- 3. What is thecloud? Our Definition • “The Cloud” is a massively overloaded term • Here, we are using it to refer to virtualised infrastructure, wrapped in an easy-to-use web service API • Infrastructure as a Service • Can be private (See OpenStack & Ubuntu) as well as public
- 4. What is thecloud? The Wider Sense • Storing something “in the cloud” has come to refer to using network-accessible resources to store objects (usually files) • Marketing around the cloud has created a very broad definition, companies and products previously operating in the Internet are now part of the cloud
- 5. How can ithelp us? Advantages • Infinite resources • Pay as you go model – no capital expenditure on infrastructure • Geographically distributed • Rapid scalability • Provisioning speed – new machines can be provisioned and deployed to almost instantly
- 6. How can ithelp us? Disadvantages • Actual hardware is managed by a third-party in a central location – issues with this hardware can cause outages • Provisioned instances don’t have concrete hardware specifications, and so sizing architectures can be difficult • Privacy – Some industries have legislative restrictions on how and where they store data
- 7. How can ithelp us? Alfresco • Alfresco Cloud – the ultimate example of a successful Alfresco AWS deployment • Client solutions – Allows the infrastructure behind their Alfresco solution to grow as they do • Cost savings – A move to operational expenditure reduces the risk of a deployment • Loaded with content – Alfresco manages content effectively, the cloud can help ensure that that content is distributed efficiently, securely and reliably
- 8.

- 10. AWS Services •EC2 - Pay-as-you-go (or reserved) compute power, delivered as a virtual server, with a number of pre-made OS images to install • S3 - Storage service, accessible over HTTP • EBS - Hard drive image service, disconnecting instances from their data • VPC - A virtual private cloud, providing VLAN-like control of network segments, and a VPN option
- 11.
- 12. DevOps What is it? • A methodology that makes collaboration the highest priority, to ensuring development and operations teams can deliver software quickly and efficiently How does it relate to the cloud? • Tools, like Puppet and Chef, have been built to help Developers and Operations get on the same page • IaaS environments create a juicy target for these tools • Automation means issues get resolved quicker, and we can do things like auto scaling!
- 13.
- 14. What is puppet? ServiceOrchestration • Puppet is a resource-oriented method of specifying what you want your nodes to look like • The how of ensuring a given node looks like its specification is taken care of by puppet • Resources in the node specification typically take the form of abstracted concepts, such as a “service”, a “file”, a “mount” etc.
- 15. Back to front? Puppet Master 1 3 Puppet Puppet Agents Puppet Agents Agents Puppet Certificate 2 Authority The Puppet Agent drives updates • On every node in an environment, the puppet agent needs to be installed • This agent discovers the master from DNS
- 16. Resource driven •[Tomcat must be installed] • [Tomcat must be started] • [Imagemagick must be installed] • [alfresco-global.properties must have these values: dir.root=/opt/alfresco swf.dir=/opt/alfresco/swf ] • [The alfresco and share webapps must exist, copied from this location: /opt/puppet]

- 20. Alfresco on AWS- Opportunities
- 21. What can wedo? Opportunities • Auto scaling – CloudWatch, New Relic, Nagios and other monitoring / APM tools can help you trigger actions when load hits specified limits • These actions can include provisioning new instances in AWS • An Alfresco Admin Console for AWS • Show the current status of the whole environment • Trigger actions to provision more servers • Historical usage statistics • Much, much more!
- 22.
- 23. Infrastructure setup DNS VPC • EC2 on it’s own • Security doesn’t help with requirements may persistent mandate the use of a addressability VPC • Depending on • VPCs are great, but architecture, you leave you in charge may need a way to of network setup address nodes after • They give you sticky a stop/start IPs
- 24. VPC beginnings... Internet External tier Gateway Internal tier Transform CMS Search XML RDBMS . Incoming route Outgoing route
- 25. Infrastructure setup Images Storage • Another question of • EBS provides a cloud architecture quick answer, but • Do you bootstrap reliability concerns from nothing, have a need to be base image, or considered maintain images for • Puppet artefact all of your services? storage • S3 (alfresco-cloud- store)?
- 26. Puppet challenges Automated provisioningand certificates • Often, the ability automatically deploy a node, or an entire environment is highly desirable • One option is node_aws • Setup of a Puppet Master is often required before automated provisioning can begin • Puppet Master needs to automatically sign each new node • The ability to resolve DNS internally is useful here
- 27. Puppet challenges Code Artefact development • At Ixxus, we JAR primarily use Maven (with some Ant and WAR Gradle thrown in) Repository • How do we get our developed artefacts Puppet “File” from CI to our resource application servers? Application Server

Editor's Notes
- #2 Outline Cloud advantages - DevOps mentality - AWS API - Puppet - Provisioning demo – not doing Opportunities (maybe mockups) -Auto scaling -Admin console with AWS API controls (auto scaling parameters, current load etc) Challenges (with possible solutions) DNS VPC Images S3 (as a puppet artifact store) – mention alfresco-cloud-store Puppet auto conf and signing certificates Development artefact deployment Building artefacts for the cloud
- #10 This is the EC2 console, talk around AWS
