Why Hybrid Cloud ?

 # Why Hybrid Multi-cloud

On-prem, AWS, GCP (... alibaba, Ibm cloud, ORCL)
1. Insurance against vendor lockin
2. Leverage the power of hyper cloud providers
  - on-demand IaaS
  - value added services
3. Regulatory
4. Disaster Recovery across providers
5. ORCL, VMware, IBM legacy DC incumbency reasons
  - vmc for aws, vmc for gcp, vmc for azure
  - zero change VM migration
  - vmc control plane for VMs
6. 2-10% penetration of public cloud
7. Proliferation of platforms - SINGLE Control multi-cloud plane
  - CF
  - Mesosphere
  - k8S (anthos, tmc, arc, crossplane, ..... )
  - SINGLE CONTROL PLANE

# Replication Edge <=> Central

  - Edge workloads will 75% cloud workloads
  - Call back home - Edge Architecture
  - Replicate -> offline-online
    - Data constraints
    - Network constraints
  - STATE Management
  - Cell Towers, POS, Autonomous Robots

# Stateful workloads - Databases

 - Operational pain - engineers
 - containers, VMs (legacy)
 - Operators
 - STATEFUL Sets
    - CSI
    - Portworx
 - Performance reasons for staying on a VM
 - self-service, faster changes, choice
 - Data resiliency, backup, DR (BCDR)
 - Gemfire replication (pattern)
