Agenda

• A (very) brief history
• Current problems
• What Cloudify is and what it provides
• Installing an application
• Managing an application
• Behind the scenes

A brief history (~11y back)

• Application == code --> Application == Everything
• On premise --> IaaS + PaaS + SaaS == Cloud
• Managed services --> Self service
• Prepay --> Pay per usage
• Manual construction --> API based
• SaaS scale change

Current Problems

• Disposable environments
• Post install management
• Process repeatability
• Cloud is just an API
• Vendor Locking
• Extensibility
• Multi-Cloud

             's Mission Statement

Cloudify’s mission statement is to allow organizations to realize the benefits of cloud computing by simplifying the management of cloud applications at scale

             is

• An application management framework
• Standardized (based on TOSCA)
• Anti vendor-locking
• Open-source stack
• Written in Python
• open-source
• Pluggable

                  provides

• A standardized way to manage applications
• An easy API to write abstractions
• Strong contextual capabilities
• Repeatable workflows
• OOB CM plugins (Docker, Fabric, script, etc..)
• OOB IaaS plugins (AWS, Openstack, etc..)
• CLI, Server and visual composer
• Healing and scaling workflows
• Agent or agentless approach
• A web UI

Target Audience

• Developers
• System Architects
• System Administrators

Installing an application

• Writing a blueprint
• Providing inputs
• Executing the install workflow

Managing an application

• Updating a deployment
• Executing the scale workflow
• Settings up metrics collection

CLI vs. Manager

• Centralized management (REST)
• Data retention
• Concurrent executions
• Security features
• Multiple applications
• Multiple deployments
• High availability
• Web Interface

• Simple installation
• Manage managers
• Deploy applications locally or via a manager

Development Infra

• ~60 active GitHub repositories
• PRs and CRs for each merge
• PEP8 fully enforced via flake8
• Jenkins based builds with swarm nodes
• Build flow tool developed in house
• Python 2.7

Testing Infra

• tox + nose for all unit tests
• Using unittest or testtools (considering pytest)
• Aiming for 94% unit test coverage
• Comprehensive integration and system tests
• TravisCI --> CircleCI (unit tests + flake8)
• system-tests framework developed in house
• dev-flow tool developed in house

Generic Tooling

• Repex - used for version management
• Wagon - used for plugin packaging
• Surch - used for secret detection
• Deppy - used for Python dependency and license tracking
• Tattle - used for JIRA-GitHub issue tracking
