Services everywhere...

Software as A Service

Gmail, Salesforge

Platform as a Service

AppEngine, Heroku Infrastructure as a Service

EC2, GoGrid, RHEV


6/27

Cloud computing types

Public Cloud

Private Cloud

Hybrid Cloud

Community / GovernmentCloud


7/27

Who is it for ?

For large (Fortune 500) companies, owningdata center is easy cost

For medium companies, it's unrealistic

For small companies, it's a dream

7 from 10 startups choose cloud deployment


8/27

Disadvantages when using 'in-house' server


9/27

Disadvantages when using 'in-house' server

Small is

expensive (upgrades, power, admin...)

less reliable (redundancy, failovers...)

risky (All you eggs in one basket)

inflexible (remote access is difficult)


10/27

Advantages of using 'cloud' solution

Pay as you go model

Infiniteon-demand resources

High elasticity

Minimal initial costs


11/27

Common cloud questions

Data security

Political restrictions

Connectivity


12/27

Key components of Cloud

Massive virtualization (KVM, Xen, Hyper-V)

Network (Internet in most cases)

Easy administration (API)


13/27

API ?

More convenient way for managing clouds

Gives a lot of power to end-users

Scaling your applications/infrastructure using

custom application

Using web UI is not effective


14/27

Many clouds == many problems...

Vendor lock-in

Similar to the many virtualization hypervisors (KVM,Xen, Hyper-V) before libvirt

Each provider has own API OpenStack ? (Rackspace)

Amazon EC2 API

VMWare vCloud ? (VMWare)


15/27

Many clouds, one API

Deltacloud API

Incubated under Apache Foundation (ASF)

REST based cloud abstraction API

Managing resources in different IaaS clouds

Profiting from open-source model


16/27

Deltacloud Supported IaaS providers

Implemented as 'driver':

Amazon EC2/S3, Rackspace, GoGrid, Terremark(vCloud), OpenNebula, RimuHosting, RHEV-M

Comming soon: Linode, VMWare vCloud Native providers

For developers: Mockdriver


17/27

API specification

REST API

thus programming language agnostic

supports XML, JSON, HTML

build-in documentation

Entry-point model (/api)

Collections and operations

Features (we failed here in abstraction ;-)


18/27

API capabilities (1)

Base collections:

hardware_profiles

realms

images instances

Extended collections:

keys, buckets, storage_volumes,storage_snapshots


19/27


Operations

Basic set of CRUD operations

Create (instance)

Read/List (instances, images, hardware profiles...) Update (instance state reboot, stop, start)

Destroy (instance, images)

Extended operations

Upload blob to bucket (S3) Assign instance to loadbalancer


20/27


Capabilities are reported on entry-point level

Using 'RESTish' practices

Linking between resources

HTTP status codes


21/27

Additional features

Instance authentication

User data injection

Security groups

Loadbalancers...

Features are reported in entry-point level


22/27

Clients

Ruby, Java, C (libdeltacloud), Perl,

....add your language here


23/27

Advantages of using Deltacloud API

Freedom in choosing provider

QOS (Quality of Service)

Simple fail-over

Simple migration from one provider to another

Making cloud development fun, instead offrustration


24/27

Future ?

Project Aeolus

(God of wind manages clouds)

Enterprise web application for managing clouds

Includes Image building, deploying, QoS, Quotas... Support more cloud providers (VMWare)

Native providers
