This document discusses how most enterprise applications will evolve to utilize cloud computing. It notes that businesses want to leverage existing investments but also adopt new technologies, and that hybrid applications which use both on-premise and cloud resources can help achieve both goals. The document demonstrates how a company called Skytap helps development and testing teams migrate workloads to the cloud in a fast and repeatable way. It concludes that hybrid applications, rather than just infrastructure, are the best approach for most enterprises to evolve their software to utilize cloud computing.

3. “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.

6. Point 1
Businesses want to leverage and
extend their existing investments

9. Point 2
New computing technologies almost
always augment, rather than replace,
existing technology

15. Point 3
Production software must often be
designed to work well in the cloud

17. Option 1: Punt
Eventually, disregarding the
advantages of the cloud will benefit
your competition.

18. Option 2: “Private Cloud”
Often just on-premises
virtualization. Provides value, but
the benefits are not a superset of
what the cloud provides.

19. 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.

20. Isn’t that a “Hybrid Cloud?”
No, a minimal hybrid application just
has one service or component
running in the cloud.

22. 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

23. 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

24. 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

25. 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
