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 was wondering if there's any possible solution to connect a GCP AIP tunnel to a DB (Cloud SQL Proxy) when the DB has no public IP.
I don't want to create a new VM for this purpose so I'm only interested in solutions that don't require me to use a VM.
Thanks in advance.
There are two ways to connect your on-prem network to the VPC, but both are fairly involved (and potentially expensive):
You can use Cloud Interconnect
You can use Cloud VPN to set up a HA VPN
For both scenarios, you'll also need to configure Cloud Router to export the routes to your Cloud SQL instance into your on-prem network.
Additionally (if you have control of your constraints) you could revisit the idea of using Public IP. Using the Cloud SQL Auth proxy allows you to authorize your connections using an IAM identity as opposed to traditional firewalling or SSL certs. You can even use org policies to restrict Authorized Networks, making the Auth proxy required to connect. enter link description here
Assuming I have a custom VPC with IP ranges 10.148.0.0/20
This custom VPC has firewall rules to allow-internal so the service inside those IP ranges can communicate to each other.
After the system grows I need to connect to some on-premises network by using Classic Cloud VPN, already create Cloud VPN (the on-premises side configuration already configured by someone) and the VPN Tunnel already established (with green checkmarks).
I also can ping to on-premises IP right now (let's say ping to 10.xxx.xxx.xxx where this is not GCP internal/private IP but on-premises private IP) using compute engine created on custom VPC network.
The problem is all the compute engine instance spawn in custom VPC network can't communicate to the internet now (like doing sudo apt update) or even communicate to google cloud storage (using gsutil), but they can communicate using private IP.
I also can't spawn dataproc cluster on that custom VPC (I guess because it can't connect to GCS, since dataproc needs GCS for staging buckets).
Since I do not really know about networking stuff and relatively new to GCP, how to be able to connect to the internet on instances that I created inside custom VPC?
After checking more in-depth about my custom VPC and Cloud VPN I realize there's misconfiguration when I establish the Cloud VPN, I've chosen route-based in routing option and input 0.0.0.0/0 in Remote network IP ranges. I guess this routes sending all traffic to VPN as #John Hanley said.
Solved it by using policy-based in routing option and only add specific IP in Remote network IP ranges.
Thank you #John Hanley and
#guillaume blaquiere for pointing this out
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.

I have an instance and s3 bucket in AWS (which I'm limiting to a range of IPs). I'm wanting to create a VPN and be able to authenticate myself while trying to log into that VPN to get to that instance.
To simplify, I'm trying to set up a dev environment for my site. I'm wanting to make sure I can limit access to that instance. I'm wanting to use a service to authenticate anybody wanting to get to that instance. Is there a way to do all of this in AWS?
Have you looked at AWS Client VPN:
https://docs.aws.amazon.com/vpn/latest/clientvpn-admin/what-is.html
This allows you to create a managed VPN server in your VPC which you can connect to using any OpenVPN client. You could then allow traffic from this vpn to your instance using security group rules.
Alternatively you can achieve the same effect using OpenVPN on an EC2 server, available from the marketplace:
https://aws.amazon.com/marketplace/pp/B00MI40CAE/ref=mkt_wir_openvpn_byol
Requires a bit more set up but works just fine, perfect if AWS Client VPN isn't available in your region yet.
Both these approaches ensure that your EC2 instance remains in a private subnet and is not accessible directly from the internet. Also, the OpenVPN client for mac works just fine.
