What It Really Takes to

Deploy and Manage Apps

Provision

Install

Configure

Deploy

Monitor

Scale

Quite often we end up with this..

App Centric Devops – the AWS way…


• Key abstractions– Stack (a complete deployment)– Layers (tiers)– Instances (per layer scaling)– Apps (from a repo)


• Layer def example


• Characteristics– Full stack definition– Lifecycle event handling– Auto healing– Network configuration– Chef integration– Elastic scaling

Cloudify provides the equivalent of Amazon OpsWork on OpenStack and other clouds


App Centric Devops – the Cloudify way…1 Upload your recipe

2 Cloudify creates VMs, configures network & installs agents

3 Agents install and manage your app

4 Cloudify automates monitoring, healing and scaling

DevOps Automation: Example 1• Very large U.S. hardware/software

company.• Use Cloudify for Continuous

Delivery• Stack: Cloudify, Chef, Openstack• Reason for Choosing Cloudify

– Dozens of roles across multiple orgs.– Chef shop, needed backwards compatibility.– Cloud portability– SDN support– Devops integration with existing

Jenkins/Chef infrastructure to build internal PAAS on internal cloud.

DevOps Automation: Bleeding edge• Full automation of stack deployment/scaling

across multiple AZs.• Multi-tier SDN governed stack deployments

(nets/subnets/firewalls/routers etc…)• Scaling to 1000s of nodes across org• Auto scaling based on load• Uses hosted chef for cookbook, attribute

storage.• Replaces home grown system that uses chef

server to coordinate complex/cluster deployments.

DevOps Automation: PaddyPower

• Ireland's largest online betting service.

• Use Cloudify for Continuous Delivery

• Stack: Cloudify, Chef, Cloud Stack• Reason for Choosing Cloudify

– PAAS strives to abstract provisioning and deployment thus reducing complexity.

– PAAS constrains applications to use features provided by the platform.

– Cloudify was geared to work in DevOps environment

PUTTING APPLICATION AND CONFIGURATION CENTRIC TOOLS TOGETHER

Cloudify Chef Integration(Deployment)

• Install Chef Agent• Setup Chef Server• Support existing Chef

Recipes/Cookbooks• Remote Execution• Application

Dependency• Cloud portability

Cloudify Chef Integration

(Post Deployment)

Cloudify Chef Integration(Advances)

• Advanced Orchestration– Self Healing– Auto-Scaling– DR Automation– DevOps Policies*

• Standard Recipe (Yaml/Tosca)*

Remote Execution
