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

Two Options for Portability

AWS Azure Google CloudStack OpenStack vSphere

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

Application Templates

Configure a system: Cloud Application Template (CAT)

Configure a server: • ServerTemplates (portable)

• Docker container (portable)

• AMI

• CloudFormation

• VM template

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

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

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

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

• 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
