is used for managing EC2 instances such as installing patches and software.
Systems Manager
-Extend your VPC into the on-premises data center
-Fully managed service that offers the same AWS infrastructure, AWS services, APIs, and tools to virtually any data center, co-location space, or on-premises facility for a truly consistent hybrid experience.
AWS Outposts
Seamless omnichannel experience through a single unified contact center for voice, chat, and task management.
Amazon Connect
creating a low-latency private connection to an on-premises data center but it cannot be used to extend the VPC.
Direct Connect
-CloudFormation templates that automate the deployment and a guide that discusses the architecture and provides step-by-step deployment instructions.
-Acelerators reduce hundreds of manual procedures into just a few steps, so you can build your production environment quickly and start using it immediately.

used to deploy infrastructure from templates,
CloudFormation
content delivery network (CDN) that caches content around the world for lower latency access.
-improves performance for both cacheable content (such as images and videos) and dynamic content (such as API acceleration and dynamic site delivery).
-good fit for HTTP use cases
Amazon CloudFront
Enables access to your application by leveraging the same Edge Locations as CloudFront and routing connections across the AWS global network.
improves performance for a wide range of applications over TCP or UDP by proxying packets at the edge to applications running in one or more AWS Regions.
-good fit for non-HTTP use cases, such as gaming (UDP), IoT (MQTT), or VoIP, as well as for HTTP use cases that require static IP addresses or deterministic, fast regional failover.
