Load balancer or proxy to route traffic to different servers based on their URL

I have many customers with their own nameservers, I want to give them all the same DNS details like how Squarespace or Shopify do (eg an @ A record and a www. CNAME that is always the same), and then manage which server their traffic is routed to on my end.

This would help massively when I need to migrate a lot of websites onto a new infrastructure and I don't want to spend weeks speaking to differen ...

How to assure that floating IP is taken as source address for egress traffic of VM

If I have a OpenStack VM which has a configured a floating IP address and tries to connect to a service outside the OpenStack "universe". How do I assure, that the source IP address of this connection is the floating IP address of this VM?

I have a lambda function which should invoke another lambda function asynchronously but every times I run it times out no matter how many minutes I give it to the function.

They are both in same private vpc and both are given same subnet.

Here lambda_function_2 function is asynchronous.

Nginx: reverse proxy Influxdb can't find static files

JWo

I have a setup where I have multiple service running with docker compose and one Nginx (nginx:1.19-alpine), which acts as a reverse proxy for all services and serves some static files.

One service is an Influxdb container (influxdb:2.1.0-alpine) which provides a UI for webbrowsers.
I want to reverse proxy to this container, but I get problems with the static files of this container.

Should associated floating IPs be configured/visible on VM?
us flag

perhaps anybody here inside can assist me with a problem (or question) with floating IPs. I am creating a floating IP by allocating one from a defined pool and associate it to a running VM within my project. That works fine.

What I expected is that this floating IP is being configured in the VM so that I can see it inside the VM with a command like ifconfig -a, but I can't. The floating IP is not visibl ...

Is it bad practice to run `net start ""` on an already running service (or a service whose status I don't check beforehand)?

Disclaimer I'm not familiar with these subjects (services, net command, and server maintenance in general).

On Windows, the net command allows to stop and start services, via net stop "<service name>" and net start "<service name>"

Is it bad practice to run net start "<service name>" on a service whose status is not checked beforehand?

How to replace an url part through htaccess

Migrating React app from App Engine to Cloud run LB configuration

We tried to migrate our front end app from App Engine to Cloud run.

We did the following steps

  1. Created a LB, so we could direct traffic to the correct Cloud run APP.
  2. Changed DNS A records from App engine pointing to LB's external IP.

Traffic began flowing into cloud run , BUT we started to see some off the traffic still redirect to the app engine and got 404.

Apache WampServer - Getting "It works!" only with https

I am using WampServer 3.2.3 (Apache 2.4.46) and I added an SSL certificate on a virtual host, but when I go to this virtual host's whebsite with http, it displays the configured page. The problem is that when I go with https, the website shows the default page "It works!".

I searched for "htdocs" (the path where the file is stored) in httpd.conf and httpd-vhosts.conf, but I don't have any result.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
