My organization has an AWS presence, but no VPN nor Direct Connect to and from our on-premises data center. We would still like to leverage DynamoDB in the short-term without having DirectConnect or a VPN connection in place. We will not be using any EC2 instances for our web services. Is it possible for an on--prem host to talk to DynamoDB without any AWS networking infrastructure in place....basically a call direct to the DynamoDB service without VPN or Direct Connect?
All you need is an Internet connection to access DynamoDB. Your on-premis servers will need to have access to make calls to the AWS API, which is publicly accessible over the Internet.
You can use an VPC endpoint gateway to connect your server to Dynamo Db using amazon network

I have already setup Site-to-site vpn to connect on-premises server and aws vpc. It has connection between vpc app successfully.
However, the on-premise server would like to use sqs and secretsmanager too but the on-premise server doesnt have any internet connection. Is it possible to connect sqs and secret manager through site-to-site vpn? Or hv other solution? Thanks
From high level you do need a conditional DNS forwarder on your on-prem and an inbound R53 DNS Resolver on AWS. You still need to create VPC Endpoints (Interface) and that should technically allow you access those services privately.
We are moving from AWS to the GCP. I used Client VPN Endpoint in AWS to get into the VPC network in the AWS. What is the alternative in GCP which I can quickly setup and get my laptop into the VPC network? If there is no exact alternative, what's the closest one and please provide instructions to set it up.
AWS Client VPN is a managed client-based VPN service that enables you to securely access your AWS resources and resources in your on-premises network. With Client VPN, you can access your resources from any location using an OpenVPN-based VPN client.
Currently there is no managed product available on GCP to allow VPN connections from multiple clients to directly access resources within a VPC as Cloud VPN only supports site-to-site connectivity, however there is an existing Feature Request for this.
As an alternative a Compute Engine Instance can be used instead with OpenVPN server manually installed and configured following the OpenVPN documentation, however this would be a self managed solution.
I looked for in the documentation in the official AWS page to find out what are the differences between Amazon Connect, Amazon Direct Connection, AWS Managed VPN and Amazon Connect . Each time I get the question with this 4 options i am not sure which one should i use. Could anyone give me advice how to easily distinguish how to recognise correct use of this services ?
Amazon Connect
This is very different to either of the other services, it is a service that operates as a Cloud based call centre replacing on-premise software solutions that would have done this in the past.
Amazon Managed VPN
A VPN (otherwise known a virtual private network) allows a connection to be established over the internet to your AWS VPC(s). AWS has 2 versions of this, a site-to-site VPN and a client VPN.
The site-to-site VPN offers a fixed VPN connection between your AWS VPC and an on-premise location. This will require a static IP to maintain the connection, with all traffic routed over the public internet via IPSec and IKE.
The client VPN is similar to the site-to-site but will allow the client connection from anywhere. Using OpenVPN software you establish the connection with AWS which is maintained for as long as the connection is alive. This again uses the internet for all communication.
Direct Connect
With Direct Connect you can maintain a dedicated connection between AWS and your on-premise. This means you will no longer be using the public internet to connect which improves the performance between your on-premise and AWS. It supports both connections to VPC and connections to the public services of AWS (those not in a VPC such as S3 and DynamoDB).
There are a range of network speeds to choose from upto 10GB, to establish this it has specific hardware requirements and will require the hardware to be hosted at a authorized site. Alternatively you can use a hosted connection from a partner who will provide this hardware for you.
I have done a clean sweep of AWS docs but couldn't find answer to my scenario. I'm looking for a solution wherein I will have private connectivity(no data flows through Internet but within AWS network) between my two VPCs and VPC to On-premise connectivity. I'm aware of AWS PrivateLink and Direct Connect but they have some limitations e.g. a RDS Instance cannot be exposed as an Endpoint service to be consumed and things like that.
Is there any way I can achieve the above ?
AWS Transit Gateway allows you to setup direct networking between VPCs and your on premises environment. It supports both VPN and Direct Connect for the on premises leg of the connection.

When to use aws direct connect and aws storage gateway. My question is these services seems to be similer, so what are use cases to use these two services.
AWS Direct Connect is a network connection between AWS and on on-premises network. The physical connection is an optical fiber link organised through a Telco, while Direct Connect provisions the physical port where the fiber connects in an AWS transit center.
AWS Storage Gateway is a storage service that provisions a virtual tape drive, virtual S3 drive or virtual disk that is stored in AWS. It typically runs across a Direct Connect connection.
AWS direct connect connect the in premisses resources with any services, while AWS storage gateway used to connects to S3 services including AWS S3 Glacier only.
This is one of the difference.
"AWS Direct Connect is a network service that provides an alternative to using the Internet to connect customer's on-premise sites to AWS" (AWS Docs).
"AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage" (AWS Docs).
Direct Connect creates a private network connection btwn AWS and on-prem resources while Storage Gateway enables you to store and retrieve Amazon S3 objects through standard file storage protocol.
Storage Gateway - As the name suggests, this service is used to connect on-premises infra with STORAGE services (specifically S3, FSx, EBS)
Direct Connect - This service is used to connect on-premises infra with any AWS resources (in any region)
