To convert an existing AWS EC2-classic infrastructure into a VPC orientated architecture. We need a multi-subnet (public and private) arrangement for web-servers, RDS instances and application/worker servers. Security groups, firewall, route tables etc need be set up according to server/subnet requirements e.g. application servers within the private subnet should not be internet accessible (further details to be supplied).

I'm with https://www.tmzvps.com/ddos-protection/ And I'm using KDM-2G / $41/mo. The problem is that I have domains that are not loading for me, but they are loading for others. Also some domains load extremely slow. I've contacted TMZ many times about this and we've been sending tickets back and forth but they can't seem to solve the issue. They've run several tests and all they say is that everything works fine. But obviously it doesn't work fine, because I can't load my websites and if they do load it takes ages. So that is not fine for me. I've had the issue before and someone managed to solve it for me, but that person is not available now. I'm seriously considering to move everything to a new server provider. So I'm looking for advice and help. First I would like you to take a look and see what is wrong. If you think you can fix, we fix it. If not then you help me move everything to a new server. I'm not really good with the server side of things, so even if I move everything...

We currently have our emails and website and a few custom scripts running on a computer in one of our offices on an adsl2+ connection. It has been great in the past but we are growing and now it is struggling just to keep up with emails. We have purchased a hosting package with hosted emails/website aswell as a barebones VPS... I want to minimise downtime but I would like for somebody to setup and move the website, emails and these custom scripts (might get the developer to do the custom scripts) to the new hosting system and then finally deal with the DNS shuffle once it is all set up. I want somebody who knows their stuff. I dont want to be explaining to somebody what FTP is. Old server is running debian linux. New hosting is with Crucial hosting in Sydney. I really would like to find an absolute guru who can assist us in the future whenever we have a linux need.

Hello, I am in the process of designing a service which processes inbound emails according to customer configured rules and provides alerts via text message and/or email. I need someone who can set up a distributed email system and also create the evaluation system, using AWS to provide automatic scaling and high availability (I have experience on the AWS side so it's not as important). It's also possible that we would decide to go the route of creating this in a non-scalable fashion to simply provide proof of concept, the ideal candidate would be able to provide advice and input on the decision making process and not just take a set of requirements and execute them. UI design skills are not important as you or I will simply create an extremely basic UI to get this going and then revise it if there is interest in the service. Regards, Larry Bly
