Amazon Web Services (AWS), is a collection of remote computing services, also called web services, that make up a cloud-computing platform  operated from 11 geographical regions across the world. The most central and well-known of these services include Amazon Elastic Compute Cloud, also known as "EC2", and Amazon Simple Storage Service, also known as "S3". Other services include Elastic MapReduce (EMR), Route 53 (a DNS web service),  provides a highly available and scalable Domain Name System (DNS) web service, Virtual Private Cloud (VPC), storage, database, deployment and application services.

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

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 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.

Managing Security Policy in a Changing Environment
Managing Security Policy in a Changing Environment

The enterprise network environment is evolving rapidly as companies extend their physical data centers to embrace cloud computing and software-defined networking. This new reality means that the challenge of managing the security policy is much more dynamic and complex.

We have our corporate public website hosted on an internal server. We want to use Amazon Route 53, and the Health Checks feature to monitor this website, and automatically redirect visitors to an "under maintenance" page (hosted in an S3 bucket) in the event that the primary site goes down.

I have everything working like this:
- Route53 PRIMARY record: --> [IP Address of internal Web Server]
- Route53 SECONDARY record: --> [ALIAS for S3 bucket] --> S3 Web Redirect for all requests --> (S3 bucket)

This all works great. If the primary goes down, visitors are redirected to

However, the problem is that browsers seem to be caching the redirect and maintenance page, so even once Route53 has switched back to the PRIMARY record, if the visitor tries to go back, they go straight back to the page. Even closing and opening the browser doesn't help. Only manually clearing the browser cache, or switching to a different browser seems to help.

Any idea on how I could change anything to get the 'failback' working better?
Hi Experts,

I get the following error on the console for running the reactjs application.

   AJAX Failed: SyntaxError: Unexpected token < in JSON at position 0

Open in new window

on the developer tools console window. I got the following error.
 search-e3e9d0f9da88f042e3cb.js:446 Warning: React attempted to reuse markup in a container but the checksum was invalid. 
This generally means that you are using server rendering and the markup generated on the server was not what the client
 was expecting. React injected new markup to compensate which works but you have lost many of the benefits of server rendering. 
 Instead, figure out why the markup being generated is different on the 
 client or server:
 (client) " data-reactid="18">Medium</div><button 
 (server) " data-reactid="18">Large</div><button s

Open in new window

It is wagtail application(it is like Django-cms), in which react module is called inside the wagtail application. The development environment is Ubuntu on aws.

Please help me in resolving this issue. I am not able to find the origin of the error.

I need to migrate a VM to AWS.  

Does anyone have the instruction to install the plugin for the vsphere console and export?  

I've recently set-up 3 Load-Balancers with 12 different Target Groups.

I'm looking to create a either an AWS CLI or Powershell script where I can send all traffic to one server (say, for the purposes of Maintenance and restarts).

Does anyone have, or would be willing to share, an AWS CLI script that allows me to essentially control the flow of traffic?

Thank you for your help.

I have an Ubuntu OS server running on AWS. The size is m4.2xlarge (8 Cores and 32 GiB of memory) and the server is not in production yet but it does have abnormal CPU Utilization and varies for no reason. I'm using RunCloud ( for the server management. The following is a week-long graph on CPU utilization. The peaks is a cron job running so that is as expected but the fact that the CPU utilization varies I can't figure out why. I have already disabled the cron jobs which does not solve this problem. I have run out of ideas to check why I get this abnormal CPU utilization. Can someone help me?

Hi Experts,

      Elastic search is not picking up after adding new indices to that data path.

I had also restart the elasticsearch service, still not picking up the new data.  

I had checked with
sudo curl -XGET '' produces the same results. after moving many indices files to that folder.

yellow open   ntdl_v01 Cfx3yS5WRYiwJkOctqexqw   5   1          0            0       955b           955b

it returns the same old indices.

Will the new indices be under the same ntdl_v01 index, if I copy the new indices files to that folder.

How to maintain the same ntdl1_v01 without changing the index name by adding adding more indices files and folders to it.

Please help me in resolving this issue

We are having a problem trying to login to particular Amazon EC2 Server through RDP

For no apparent reason we will get this message
Even though no other users are logged in

And the only resolution is to reboot the server.

Any ideas?  Where could I see what is causing this?

****While My Question was Pending I learned the Dell PS6510E Unit is not a server and is for storage but any ideas on how I can use this to my advantage*****

I am a Newbie in this department for sure. I have been running a Website on the AWS EC2 T2.Medium Ubuntu Linux for the last 2 years and I am rethinking some options. I have in our inventory a Dell PS6510E server that I came across and I have not tinkered with it yet.

Real Questions?????
Which would be faster and more reliable?
What is some insight or things I may be overlooking?
For AWS I know it is Sky's the limit on growing down the road but how far can the Dell PS6510E get me???

I am constantly import to my EC2 large amounts of files and this is eating up my CPU Credits and the time it takes is crazy.

I know every situation is different but i really need some guidance on if I should just stick with AWS or if this Dell PS6510E has real potential for growing or not.  Also the PS6510E is discontinued but I already have it. I thank you all for the help.

Here is the link to the Dell:
