AWS 弄出了 AWS Dedicated Local Zones,很像 AWS Outposts...

AWS 推出了 AWS Dedicated Local Zones:「Announcing AWS Dedicated Local Zones」。

先講 AWS Outposts,他就是提供 AWS 自己的硬體,放到用戶的機房裡面,所以依照需求有不同大小的機器,甚至是整個機櫃:

AWS Outposts is a family of fully managed solutions delivering AWS infrastructure and services to virtually any on-premises or edge location for a truly consistent hybrid experience. Outposts solutions allow you to extend and run native AWS services on premises, and is available in a variety of form factors, from 1U and 2U Outposts servers to 42U Outposts racks, and multiple rack deployments.

在「What is AWS Outposts?」這邊有詳細列出有哪些服務可以跑在上面,可以看到主要就是基礎服務,以及一些吃 local 特性的服務。

另外在「How AWS Outposts works」這邊可以看出架構上會在同一個 VPC 裡面,但是不屬於同一個 AZ 下:

而這次推出的 Dedicated Local Zones 還是有些地方沒看懂跟 AWS Outposts 差在哪裡,看起來很像是重新包裝而已...

首先是首頁提到的,這邊有提到 AWS Nitro System,所以猜測這是 AWS 的硬體,而不是自己的硬體:

Build with AWS managed secure cloud infrastructure

Benefit from the same AWS security standards that apply to AWS Regions and AWS Local Zones and are delivered with the security of the AWS Nitro System to help ensure confidentiality and integrity of customer data.

另外在公告裡面提到的服務,跟 Outposts 有些差異:

AWS services, such as Amazon EC2, Amazon Virtual Private Cloud (Amazon VPC), Amazon Elastic Block Store (Amazon EBS), Elastic Load Balancing (ELB), Amazon Elastic Container Service (Amazon ECS), Amazon Elastic Kubernetes Service (Amazon EKS), and AWS Direct Connect are available in Dedicated Local Zones.

另外在「AWS Dedicated Local Zones FAQs」這邊則試著說明兩者差異,但就這些句子看起來,只是不同面向的東西:

Q: How are AWS Dedicated Local Zones different from AWS Outposts?

AWS Outposts is designed for workloads that need to remain on-premises due to latency requirements, where customers want those workloads to run seamlessly with their other workloads in AWS. AWS Outposts racks are fully managed and configurable compute and storage racks built with AWS-designed hardware that allow customers to run compute and storage on-premises, while seamlessly connecting to AWS’s broad array of services in the cloud.

AWS Dedicated Local Zones are designed to eliminate the operational overhead of managing on-premises infrastructure at scale. Some customers have long-term, complex cloud migration projects and need infrastructure that seamlessly scales to support their large-scale demand. Some of these customers represent the interests of a customer community and also need multi-tenancy features to efficiently coordinate across their stakeholders. Dedicated Local Zones enable these customers to reduce the administrative burden of managing their own infrastructure on-premises with scalable, resilient, and multitenant cloud infrastructure that is fully AWS-managed and built exclusively for their use.

另外回到首頁看使用單位,目前是 GovTech Singapore,看起來就是重新包裝?

另外一個猜測是在客戶的機器上面裝 AWS Nitro System,然後裝 AWS 的軟體?這就有點怪了,而且這樣相容性之類的問題也頗麻煩,也許要指定配合的機種?

等有機會遇到的時候再跟 AWS 的人問問看好了,目前也還用不到...
