Migrating applications to the cloud requires a clear understanding of both business and technical considerations. In addition, you will want to ensure portability among clouds to avoid lock-in. Here we define technical options for cloud portability and how to assess application suitability for migration.

13. 5 Use Cases for Portability
• Most Common
• Best-venue approach
• Geography, Cost, Features
• Lifecycle approach
• Dev/Test vs. Staging/Production
• Spiky vs. steady-state
• Disaster Recovery
• Less Common
• Split-tier architectures
• Cloud-bursting

15. Two Options for Portability

Multi-Cloud Image
Configuration Scripts Containers
ServerTemplate Portability
• Script-based
• Scripts that configure
appropriately for each
cloud
• Container-based
• Deploy code via Docker
containers
• Combo of both
• Use scripts to configure
Docker hosts and containers
to deploy code

27. Cloud Infrastructure Considerations
Technical Considerations
• User-controlled IP address space, routing, etc. is possible with many IaaS
offerings
• Use of VPN functionality can “extend” on-premises datacenter to the cloud
securely
Network Connectivity
Scale-down
Logic
Master/Master
Database
configurations
• Several IaaS vendors support dedicated links (AWS Direct Connect, Azure
ExpressRoute)
• Security, latency, complexity reduced
• Varying port speeds (and cost structures) available
Physical Connectivity

28. Cloud Infrastructure Considerations
Technical Considerations
• Public Internet (usually) required, thus latency targets can be difficult to achieve
• WAN Accelerators can be of great benefit in certain situations
Latency
Scale-down
Logic
Master/Master
Database
configurations
• Typical SAN/NAS configurations not available
• IaaS vendors provide object storage options (non-POSIX compliant)
• Shared filesystems need to be self-implemented
• GlusterFS
• Ceph
• OpenAFS
Storage

29. Cloud Infrastructure Considerations
Technical Considerations
Scale-down
Logic
Master/Master
Database
configurations
• Network
• VPC, Virtual Network, Cloud Networks, etc.
• Data
• At-rest: Some vendors provide encrypted block and/or object storage
• In-flight: HTTPS, SSL, TLS, etc.
• Third-party tools also available for data at-rest encryption and key
management
Security

30. Migration Tool Realities
• AWS VM Import/Export, etc.
IaaS Vendor-Supplied
Scale-down
Logic
• Entire industry sprouting up around this use case
• Varying approaches
• Automation
-Storage and networking ignored or reconfigured
• Container/Wrapper
-VMs run in third-party container
-Adds overhead impacting performance
• Combination: Automation & Manual
-Networking and storage can be duplicated
-Scalability questionable for large (dozens to hundreds of VMs) deployments
Third-Party Tools

31. • Hybrid cloud is the dominant model for enterprises
• You have to decide which workloads to move to cloud
• Apply a technical filter to identify segments
• Apply a business impact filter to identify priority
• Apply the appropriate strategy for migration to cloud
• Manage Natively
• Migrate Once
• Make Portable
• Portability provides a lot of flexibility and benefits
