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.
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.
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.
EC2 Mac instances are dedicated Mac mini computers attached through Thunderbolt to the AWS Nitro System, which lets the Mac mini appear and behave like another EC2 instance.
Amazon EC2 Mac instances are available as Dedicated Hosts through both On Demand and Savings Plans pricing models. The Dedicated Host is the unit of billing for EC2 Mac instances. Billing is per second, with a 24-hour minimum allocation period for the Dedicated Host to comply with the Apple macOS Software License Agreement. At the end of the 24-hour minimum allocation period, the host can be released at any time with no further commitment.
Our customers use Dedicated Instances to further their compliance goals (PCI, SOX, FISMA, and so forth), and also use them to run software that is subject to license or tenancy restrictions.
Dedicated instances are optimized for workloads where consistent performance is required or where full-duty work (100% CPU all day, every day) needs doing.
For InnoDB buffer pool size (based on this article), consider allocating 80% of physical RAM for starters. You can increase it to as large as needed and possible, as long as the system doesn’t swap on the production workload.
For InnoDB log file size, it should be able to handle one hour of writes to allow InnoDB to optimize writing the redo log to disk. You can calculate an estimate by following the steps here, which samples one minute worth of writes to the redo log. You could also get a better estimate from hourly log file usage with Percona Monitoring and Management (PMM) graphs.
