3-part outline: 1. Why evolvable technology matter: technology agility is the brother of a) continuous improvement in processes and b) continuous learning in people 2. What is multicloud and hybrid cloud, Why end-to-end and top-to-bottom 3. What is evolvable and agile mean for multicloud IT platforms: in multiple layers of app/platform engineering, devops pipeline engineering, cluster ops and site reliability engineering, and IaaS or infrastructure & ops engineering - special focus on SDN here.

TODAY
A brief history of highly effective IT
LINES BLUR BETWEEN IT AND BUSINESS
• IT leaders shape the future of the business innovation
• IT owns most of the customer experience
INNOVATION IS AN IMPERATIVE
• As disruption impacts every industry: The choice is in between predator or prey.
• Focus is on technology that is differentiating. Drab tech is kicked is SaaS
SECURITY IS A MUST
• More threatening than competitors, breaches are devastating
• Must be pervasive in culture, processes, applications and infrastructure
AI IS HIGHLY ANTICIPATED, AND NEEDS PLANNING
• Business plans for AI are well defined: 23%, Technology plans for AI: 20%*
• New levels of market, business, and operations awareness

15. WHAT IS IT?
WHAT ABOUT HYBRID CLOUD

16. BUSINESS MOTIVATIONS FOR CLOUD CHOICE
Defn. HYBRID CLOUD:
Hybrid cloud spans at least one public and one private cloud
Better modern use: A unified platform that spans multiple clouds
HYBRID CLOUD – WHY?
VENUE:
• Geography for reach, migration, compliance or sovereignty
• Cost advantages
• Feature advantages
RESILIENCE:
• Disaster recovery and avoidance site
• Active-active setups for high availability
AGILITY:
• Speed of abstracting away infrastructure for developers
• Circumvent challenges: budget, staff, experience
• Hardware & software innovation pace of hyper-scale clouds
FLEXIBILITY:
• Design split-tier applications for best of both worlds
• Lifecycle / environment for dev, test, staging, production
• Bursting (seasonal, occasional etc. spiky usage vs. steady usage)

17. LUCK FAVORS THE PREPARED
Hybrid cloud prepares enterprise IT by design for infinite scale and choice
HYBRID CLOUD – BEST OF BOTH WORLDS
THE GOOD:
• Global infrastructure platform
• Ecosystem: Big Data, Machine Learning, IoT Platforms
• Economic flexibility and alignment with value
• Instant and elastic scale and failover possibilities
• YES! Security – expert SecOps in large clouds
THE BAD:
• No end of amortization – A perpetual investment
• Platform and data locality lock-in
• Aspects of unpredictability
PUBLIC CLOUD
THE GOOD:
• Control and compliance over location and systems
• Data sovereignty and locality
• Custom SLAs, platforms and hardware
• Trust for mission-critical workloads and security
THE BAD:
• Time and skill to build/maintain/scale the platform
• Reserves and CapEx beyond current needs
• Aspects of inflexibility
PRIVATE CLOUD

18. EVOLVABLE
HYBRID MULTICLOUD

19. MULTICLOUD IS THE NEW IT – HOW?
FOR A MULTICLOUD UNIFIED PLATFORM, PARITY = PORTABILITY
• Functionally compatible: APIs, infrastructure and platform primitives, config behavior
• Non-functionally compatible: availability, performance, QoS
• Economically compatible: no prohibitively drastic cost differences

20. MULTICLOUD PLATFORM
Unified Cloud Platform
• Application and DevOps pipeline portability and mobility
• Multicloud I&O management and orchestration
• Consistency and parity of core experience
• Economic optimization with flexibility
HYBRID CLOUD PLATFORM
Doing everything, all at once!
• Context switching efficiency loses
• Poor portability of DevOps automations and apps
• Cloud data and services lock-in
• Long-term management and cost control nightmare

21. SEPARATION OF CONCERNS
- layers not silos –
• App Engineering
• Platform Engineering
• DevOps Pipeline Engineering
• Cluster Ops and SRE
• IaaS EngOps: Network, Security, Storage, VMs & Metal

24. MULTICLOUD EVOLVABLE ARCHITECTURE
MULTICLOUD-READY apps and platform
• Services as a Platform SaaP is sticky. Easy but not portable.
(e.g. SaaP = plethora of AWS services, or those of many public clouds)
• Don’t use custom cloud services when you can BYO
(e.g. API gateway, auth, DB, message queue, etc.)
• Easier BYO packages and portability with tools like K8s Helm
• Find multi-cloud shims like Minio for S3-like obj. storage
• Avoid API lock-in: OSS-based managed services if can’t BYO
(e.g. Managed MySQL, Kafka, etc.)
• Else, lock-in for business advantage of unique offerings

25. MULTICLOUD EVOLVABLE ARCHITECTURE
MULTICLOUD-READY DevOps
• SaaP example: AWS CodeStar not portable
• Portable examples: Jenkins, Spinnaker
General guide:
• CI/CD and gitOps: test automation, deployment pipeline as code
• Consistency between environments: Dev/Test, Staging and Production
What about SDN?
• If you have different IPAM, DNS, Policy, LB, etc. in staging vs. prod
…then you break consistency between environments!
• Ensure the same setups between environments
• Need SDN + DevNetOps – SDN as code, and then SDN CI/CD
• Make this simple or invisible for app and platform engineering
• Multi-tenant/env. SDN makes this easy, instead of one SDN per env.

26. MULTICLOUD EVOLVABLE ARCHITECTURE
MULTICLOUD-READY Cluster Ops
• SaaP example: GAE, ECS, etc. not portable
• Portable examples: Kubernetes, Mesos, Nomad, OpenShift…
General guide:
• Clusters aaS: Avoid lock-in using OSS managed services if can’t BYO
• KaaS with serverless containers: better value; Pod = multicloud standard
• Cluster lifecycle (as code): Avoid DSLs by using Terraform or multicloud
shims to setup and scale clusters
What about SDN (with Kubernetes)?
• Multi-tenant/env. SDN makes multi-use/project clusters much simpler
• InfoSec as code: Some SDN security policies, tenant isolation, etc.
• Much variance in KaaS networking/GLB/NLB is unified in some SDNs
that implement Service type: LoadBalancer and Ingress

27. PROOF YOU CAN DO IT

28. MULTICLOUD EVOLVABLE ARCHITECTURE
MULTICLOUD-READY I&O Engineering
• Physical infrastructure itself isn’t portable, but…
General guide:
• IaaS shims make portable automation: Terraform, Minio, Digital Rebar,
• Some primitives and APIs are more portable than others: image formats,
object storage, volumes, networks, firewalls, base OS, auth, etc.
• Artifacts and config as code for software-defined and physical systems
• Copy production environment data into staging for realistic testing
What about SDN?
• Overlays provide separation of concerns and network/security isolation
• Multitenancy is required because of many projects to support
• Choose SDNs for any underlay: physical IP network or cloud IP network
• Choose SDNs that integrate with many orchestration systems
