I am working for a utility company. For hosting we use Linode right now.

I wanted to set up some form of redundancy in the event that the website goes down.

So I was thinking about using failover. As I understand I would need two (or more) web servers and two DNS servers. Is this correct?/

I was going to have one web server with Linode and one with AWS. For DNS I was going to have one with Linode and one with AWS.

Does this sound like a good setup?
If I wanted to transfer data from my data center to AWS S3 at a rate of 80Gbps - what would be my options?
Hello, we are currently migrating some websites into AWS VPS hosting (or whatever they call it I’m not in billing), and want to know what other people use as a DNS provider, does AWS provide DNS services, if not what DNS providers do you use to host websites.
In particular we are looking for DNS services that can do things like SPF and DKIM etc.. (so not afraid DNS)

I thank you for your help in advance.
This is using AWS Amazon Linux instance. I want to setup clamav onto this instance. Please see the setup as follows,

If your data center is in the same data center as an AWS Availability Zone data center - would it be
possible to create a Direct Connect just by patching from your gear to theirs? That is - is there a
way you could avoid some of expense of a carrier getting packets to/from AWS by virtue of being
physically located in one of their data centers?
Starting with AD FS in Windows Server 2016, you can now create an AD FS Farm without domain admin privileges. Following the steps outlined in the following blog,, is there a way to enable AD FS Device Registration? It seems that this step would still require domain admin rights. With services such as AWS Microsoft AD directory, AWS exclusively retains the enterprise administrator account of the forest and domain administrator account for the root domain to deliver the directory as a managed service. As such, we need another way to get the Device Registration service enabled. AWS allows you to extend/modify your AD schema by adding new object classes and attributes via an LDIF import. Could this be a possible workaround?
What is the process needed to get the AWS KVM and ZEN drivers loaded in a VMWare Ubuntu 18.04 LTS System before we use the AWS migration tool to put in on an AWS Instance ?  I’m specifically needing what and how to preload the drtivers etc.

I am getting ready to hire a contractor to write and Amazon AWS script to check our RDS instances daily and shutdown two of the three RDS instances if they are online. I was told it would take 80 hours to write such a script. I feel like this is a huge amount of time, and I want to confirm with someone here who is more knowledgeable in AWS script writing. Does that sound right?

Connecting to MySQL database with Amazon Web Services (EC2) and PHP.


I have an AWS (EC2) account set up with PHP, MySQL installed and running an Apache server.

I am trying to make a connection from my PHP application to my MySQL database which is running on the same server.

I am using this in my PHP to connect to the database:

mysql_connect("localhost", "root", "pw1");

However, I am getting this error in the log file:

PHP Fatal error:  Uncaught Error: Call to undefined function mysql_connect()

I am brand new to this so this is likely to be a configuration issue or just the approach I am using. I have searched the AWS documentation and online forums for answers, but none seem to fix the issue. Any help here would be greatly appreciated.
If you use a VIF - I understand you can attract all your S3 traffic over the Direct Connect circuit instead of going to the public internet. Is the full set of addresses to be used for S3 published anywhere so that we could create the right set of BGP filters to make sure that only the desired S3 traffic gets attracted to the Direct Connected instead of just going to the Internet?

Currently the path from our internal hosts to S3 storage is via the Internet to Amazon public IP. The goal is to get that traffic to go over our Direct connect circuits. I believe the method is using VIF and then those addresses get advertised via BGP over the DX. I want to filter those routes so unintended traffic doesn't go over the direct connects.

I have an EC2 instance, as well as a S3 bucket.

I have mapped to the S3 bucket from the EC2 instance successfully, using a third party app called ExpanDrive, it maps as a Z drive.

I have done the same from my local PC. Also mapped as a Z drive.

I can save a file into my new Z drive, and it appears immediately in the corresponding Z drive on the server.

Problem is, the document management system we have installed on the EC2 instance has an automated collection facility where it collects and ingests any files dropped into the shared folder, but it is failing. Log files say it is access denied.

We tried running the application as administrator - no change.

Can an AWS guru please advise on what might be necessary here?

Many thanks in advance.

Re Amazon S3 Modified Date... Yesterday we had to download a file from S3 and realized that the new Modified Date of our file, after we downloaded it, was yesterday's date rather than the original Modified Date.  We searched around for conversations about this and learned that it is a long-standing issue with S3 (though some would suggest it is by design, in that S3 is not "file" system; rather it is an "object" system).

Ok, but the problem still exists, and we're not interested in devising some VB solution or using a 3rd party program to maintain that attribute.  Is there yet a "standard" solution for this in S3?  Assuming not, can someone recommend another well-supported repository for our backups that WILL maintain the file attributes (i.e. OneDrive, Azure)?

Thank you...

Update:  One solution we found was, if using Cloudberry Restore, Cloudberry retains the Modified Date.
I need help with static routing for an AWS managed Vpn connection to a either a Greenbow VPN client or another AWS VPC. I am a developer, not a network engineer, but I have set up both hardware and software VPNs in the past, just never AWS managed. I know the easiest way is to just peer the VPCs together but that is not how we want to set it up. First off I am not sure if you can even connect two VPCs using the AWS managed VPNs. From what I have read they can not initiate connections, only receive them so manged to manged may not be possible.  We tried setting up a Greenbow VPN client on a VPC with no manged VPN connection and when we try to connect we are able. The problem is that we can not ping any machines. All firewall rules are configured properly ( we can ping using the external IPs). Basically we have the windows firewalls turned off and the AWS security groups allowing all traffic between the two VPCs. Here is where I believe the problem is and it comes with question. We set the VPN connections to use static routing and added a route to the managed VPN subnet routing table specifying the subnet that the Greenbow client is in and used the managed gateway as the target. On the Greenbow side we configured it with the subnet we want to reach on the managed VPN side. so Here is an example to make it more clear:

Our side of the VPN (the one with the Managed VPN connection) subnet: mask
Client side of the VPN (the one with the Greenbow client) …

I am having an issue with my Amazon EC2 Instance. I want the information panel that appears on the top right of the instance when you access it (as displayed in the image below) to be modified. Is there a way to add lines of information from sources like one of the instance tags?

If someone has a solution to this that would be excellent. Thank you for taking the time to read this :).

Could someone advise me how you could set something up on AWS that would be like or exactly a streaming media server? I use that term because I heard others call it that. I want to play media from a website, and I do not want the user to be able to download the content. I do not mean something that is simple like; not have a download button. I mean when the user comes to the site with things like IDM it just cannot be done. I would like to accomplish this most simply. I do not want to pay anybody for this I want to learn about the technology to accomplish this myself. I am not asking how to do it; I am asking what technology do I have to learn about and implement on AWS to accomplish this (keywords links etc.). Thanks

for user of MySQL and MariaDB, what tools and way you all to debug performance down to query level. e.g. which part of the query slow everything down?

please share.

if move to RDS by AWS, still easy to debug ?
