Lesson Learned from Public Clouds for OpenStack Projects

@duongkai  

About me •  An engineer at Telco •  Interested in cloud

stuff •  It’s my personal view.

What I am using •  DigitalOcean -‐ personal stuff •  AWS -‐ working stuff •  OpenStack for Food •  Others: Google Cloud,

Linode, Rackspace, HP Cloud for fun

WHERE ARE WE GOING? Before we go

Why we want OpenStack? •  Hot term? •  VMWare alternatives? •  Choose it because of no alternatations? •  For others?

A cloud is a Service and not just Software.

OpenStack is

a Cloud Controller Software

So what I learnt •  Service Delivery •  Service Management •  Cost Optimization •  Elastic Infrastructure •  DevOps culture

SERVICE DELIVERY What I have learnt

AWS

Digital Ocean

https://wiki.openstack.org/wiki/Programs

Actions •  We know what we want

ü Customers ü Current IT processes ü Which services will we deliver? How

•  VMs management solution •  Complete private cloud (﴾IaaS)﴿

SERVICE MANAGEMENT What I have learnt

AWS

Digital Ocean

Let’s imagine •  A hardware infrastructure with dozens of

servers. •  Hundreds of VMs are running on.

è How to Manage IT EFFECTIVELY

Actions •  Class of service with SLA •  High-‐availability from hardware to software •  Automation is the best friend •  Processes, Change management,… è ITIL? •  Microsoft Operations Framework (﴾MOF)﴿ is a

good start.

COST OPTIMIZATION What I have learnt

Cost is always a Problems

COST •  Hardware, network equipments •  Operation costs •  Capacity planning and procurement •  Investment

Azure

AWS

AWS’s low prices •  Custom hardware •  Supply chain efficiencies •  Scale •  Frugality

Actions •  Classes of HW – Commodity hardware is prefered to Brand HW – SANs or iSCSI – Appliance??? NO – VMs density. Storage density

•  Software controls everything •  Automation vs Manual

Open Compute Project

ELASTIC INFRASTRUCTURE What I have learnt

Elastic Infrastructure •  Easy to scale. Scale in mindset •  Know your business carefully. •  Think big, Start small. •  Capacity Planning is a must-‐work •  Know your demand.

DEVOPS CULTURE What I have learnt

DevOps •  DevOps (﴾a portmanteau of development and

operations)﴿ is a software development method that stresses communication, collaboration and integration between software developers and information technology (﴾IT)﴿ operations professionals. DevOps is a response to the interdependence of software development and IT operations. It aims to help an organization rapidly produce software products and services.

DevOps

•  Use of agile and other development processes and methodologies

•  Increased usage of data center automation and configuration management tools

Software is Eating the world(﴾*)﴿

Infrastructure as Code

Actions •  Learn how to program. Automate daily tasks •  Learn using Configuration Management

software •  Communicate effectively among developers

and ops •  OpenStack API
