We Believe in an Open Cloud Model:Open Source, Open Standards

• Cloud portability/interoperability

• Avoiding vendor lock in

• Broad community support and

collaboration

• Adapting to enterprise

standards

• Best of breed technologies

Characteristics of Clouds

Types of Cloud Service Models

SOFTWARE AS A SERVICESingle application, multi-tenancy, network-based, one-to-many delivery of applications, all users have same access to features.

PLATFORM-AS-A-SERVICEApplication developer model, Application deployed to an elastic service that auto scales, low administrative overhead. No concept of virtual machines or operating system. Code it and deploy it.

INFRASTRUCTURE-AS-A-SERVICEServers and storage are made available in a scalable way over a network.

SaaS

PaaS

IaaS

9

• Managed High-Availability

• Obtain provisioning networking services

- Load balancing, dhcp, routing, VLAN allocation

- Firewall, isolation, VPN…

• Allocate VM/Resources based on algorithms and availability

• Provide abstraction of and interaction with virtualization, networking, etc…

IaaS Cloud Platform Functions

10

• Provide a multi-tenant, highly segregated, interface (API or web interface)

• Allow arbitrary resources limits to be placed on accounts or users

• Track not just counts of VMs at given point in time, but usage

- Type of instance, network, storage, CPU

IaaS Cloud Platform Functions

11

• Secure, multi-tenant cloud platform

• Delivers AWS-like services to your users– Virtual servers on demand

– Virtual data center on demand

(VPC)

– Hosted network services

CloudStack at a Glance

12

Multiple Hypervisor Support

13

• Resources are hierarchically segregated into the following:

- Zones, Pods, Clusters and Hosts

• Users are separated into multi-level domains and accounts based on access to resources

• Intuitive user interface for centralized management and easy viewing of accounts, access and resources

- Users and Admins have access to the same UI

Benefits:

• Reduce infrastructure cost and management needs

• Increase in dependability and reliability

Multi-tenant

14

• CloudStack manages networking including:

- Load balancing, VPN, Firewall, Routing

- DHCP, VLAN provisioning and management

- Security Groups

Benefits:• Reduces the risk of failures due to a misconfigured network

• Decreases time spent on managing networking manually

• Increase business growth while lowering costs

Networking

15

• Works for all supported hypervisors

• System VMs such as router and load balancer are HA by Default

• Redundant router

Benefits:

• Protecting business critical applications

• Minimizing and better prepare for unplanned downtime

• Reducing Mean Time To Recovery

High Availability

16

• CloudStack is replete with a robust RESTful API

- Output in XML or JSON

Benefits:

• Allow external applications such as monitoring to perform actions and to spin up new instances in response to load

• Allow users to loosely couple external applications suchas billing and PaaS to CloudStack

Robust API

17

• Management Server/Database

• Compute nodes

• Primary Storage

• Secondary Storage

• Virtual Resources

- Router (routing, firewall, load balancer, VPN

- Console Proxy
