Citrix cloud architecture: building blocks we deploy

Openness matters

• Secure, multi-tenant cloud orchestration platform– Turnkey platform for delivering IaaS clouds

– Hypervisor agnostic

– Highly scalable, secure and open

– Complete Self-service portal

– Open source, open standards

– Deploys on premise or as a hosted solution

• Deliver cloud services 50 times faster at 1/5th the cost

• 130 commercial deployments

Since 2008 CloudStack has powered hundreds of clouds

“CloudStack has successfully penetrated the service provider market...and racked up some solid wins in the enterprise to boot.” James Staten Vice President, Principal Analyst

Workloads dictate cloud

architecture

Implement your environment

Develop your technical architecture

Determine the necessary functionality and performance

Determine how that workload will be delivered reliably

Define target workloads

IaaS Cloud

Architecture definition is a process

Workload categories give us a starting point

Managed IT Services

High Performance Computing

Disaster Recovery

Possible to categorize workloads into two sets

Cloud Workloads

Traditional Workload

Reliable hardware, backup entire

cloud, and restore for users when

failure happens

Cloud Workload

Tell users to expect failure.

Users to build apps that can

withstand infrastructure failure

Both types of workloads must run reliably in the cloud

Every cloud starts with basic building blocks

Designing a zone for a traditional workload

• Can achieve significant reliability for

applications running in one zone.

• Reliability of individual nodes is very high.

• All zone storage is replicated to a second

storage platform (synchronous or

asynchronous)

• In event of failure, images are recovered

from second storage array.

• Existing workloads will run reliably.

• Little cost benefit over existing approaches

availability zones

• No guarantee on zone reliability

• Applications designed to handle node

level failure

• DBs and Templates snapped to

object store.

• In event of failure, images are

recreated on new availability zone.

• Dramatically less expensive

Cloud Transition – General to Workload specific

• General architecture for any

workload

• Limited definitive failure/disaster

recovery strategy

• Focused on legacy or cloud app

architectures

• Workload-centric architecture

• Workload-specific failure/disaster

recovery

• Separate legacy and cloud app

architectures with interoperability

Support for both type of workloads is required

Key takeaways

1. Understand your workload and the type of cloud you

want to build.

2. Consider the services you will be delivering from the

cloud in the future.

3. Choose a platform and architecture that is flexible

enough to support you today and in the future.
