This a good book, with a kind of misleading title. Yes, it’s about hybrid cloud adoption, but with AWS Outposts, to be more precise.
AWS Outposts is a family of fully managed solutions that deliver AWS infrastructure and services to virtually any on-premises or edge location for a consistent hybrid experience.
And it’s good; it could appear contradictory that a cloud vendor offers you to run fully managed workloads on a “restricted cloud” on-premises, but it makes sense for many use cases that need low latency, local data processing or data residency.
For instance, in the Healthcare Industry: Linear accelerators, CT Scanners and surgical devices.
Some of the benefits that Outposts provides:
- Inherently Secure
- Reliable and available
- Simplicity of use
- Build once, deploy anywhere
- Leverage existing skill sets and tools
- Same pace of innovation as in the cloud
- A truly consistent hybrid experience
Some use cases examples:
A practical use case where you need to use more than one region for disaster recovery for regulated enterprises and data residency is required for compliance.
As you can see, the London Region is connected to the Outposts rack installed on-premises, using a VPN or Direct connection. All the workloads and data reside in the UK zone, and only the control plane traffic is sent to the IR region in case a disaster impacts the London region.
Low Latency & Local Processing
The ability to deploy the EKS cluster locally is beneficial when you need low latency, so keeping the cluster near the rest of the infra helps. But that’s not the only benefit; being local means that the cluster can work even if there are problems with the connections, which are not uncommon when the workloads are deployed on rough edges.
