Q&A

“The architectural choices that support the development and deployment of cloud applications affect quality and timeliness, and can be the difference between success and failure.

Point 1

Businesses want to leverage and extend their existing investments

Point 2

New computing technologies almostalways augment, rather than replace, existing technology

Point 3

Production software must often be designed to work well in the cloud

Option 1: Punt

Eventually, disregarding the advantages of the cloud will benefit your competition.

Option 2: “Private Cloud”

Often just on-premises virtualization. Provides value, but the benefits are not a superset of what the cloud provides.

Option 3: Hybrid Apps

A hybrid application spans multiple infrastructure and cloud locations, making use of resources and services from each. Components of the application may run on-premises or in the cloud.

Isn’t that a “Hybrid Cloud?”

No, a minimal hybrid application just has one service or component running in the cloud.

Candidates for migration• Services or components that aren't meeting scaling needs

• Services with quick payback through reduced costs

• New opportunities: Things you can't do easily on your own infrastructure

• Services benefiting from global reach and reduced latency to end-users

• Non-production workloads such as development & test labs

Qualities to seek out• Aligns with corporate security and compliance policies

• Self-contained and loosely coupled to other services

• Not sensitive to latency between remote services

• Idempotent protocols between services (tolerant of network hiccups)

• Already scale out and fault tolerant

Challenges you may face• Lack of federated authentication and authorization

• New deployment strategies

• Different monitoring and alerting strategies

• Various data placement decision (close to where it is used)

• Need for new IPC mechanisms

Most enterprise applications will evolve to the cloud

Enterprise migration to the cloud should focus on the creation of

hybrid applications rather than hybrid infrastructure

This still isn’t easy, but purpose built services like Skytap are

emerging to help move specific workloads to the cloud
