Hybrid Cloud
- What it is
- Cloud resources connected to on-premises infrastructure, operating as one environment.
- The common state during a migration, and a permanent architecture for many regulated organizations.
- Why
- Keep latency-sensitive or regulated workloads local while bursting or extending into AWS.
- Gradual migration without a big-bang cutover.
- The connectivity options
- AWS Direct Connect — dedicated private circuit, consistent bandwidth.
- AWS VPN — encrypted tunnel over the internet, fast to set up.
- Services that make it hybrid
- AWS Outposts — AWS hardware on your premises.
- AWS Storage Gateway — on-premises apps backed by cloud storage.
- AWS Directory Service — AD trusts between on-premises and AWS.
- AWS IoT Greengrass — cloud logic running on edge devices.
