Common Cloud Application Deployment Pitfalls

---

Performance

• designing for performance and ensuring performance goals are met can be complex in the cloud
  • cloud software often relies on loosely coupled services
  • multiple components can interact in unexpected ways

Scalability

• ability to scale requires devs to think differently about how an app should work
  • needs to be able to:
    • run across many instances at once
    • retain state regardless of instance or server
    • handle faults with individual servers cleanly
    • ensure data remains secure in transit and at rest

Interoperability

• software needs to be able to work on multiple different platforms and cloud provider environments
  • to help control costs and increase options for hosting

Portability

• design software that can move between on-premise and cloud environments
• portability concerns in cloud:
  • avoidance of components specific to certain cloud vendors
    • APIs, internal tools
    • avoiding use of these tools may require additional work

Availability and Reliability

• The many different dependencies can affect availability and reliability
  • if dependency goes down
• outage in one CSP or availability zone may affect your infrastructure
  • even if in different zone

API Security

• designing APIs securely and to work well with cloud architectures is a challenge
