Re: New Java vulnerability
For those curious, log4j is widely used for logging application errors, hence why it is so widespread. Apache has already released a fix (and several alternatives to mitigate the effect), see https://logging.apache.org/log4j/2.x/security.html ... Very serious vulnerability as it allows Remote Code Execution on the targeted server, and is already being actively exploited worldwide. The challenge now is to deploy the fixes -- not so difficult on z/OS (and there is log4j usage on z/OS but unclear that RCE can do much harm on a properly secured z/OS system -- this will vary by what application is using the log4j library). Cloud could be brought to its knees. There is a rumour that an electrical network was minutes away from being shutdown (nationwide blackout) from this exploitation (no mainframes involved).

Banks will never do what’s economical at the expense of risk. Mitigating risk is what banks do. The mainframe continues to get MORE ECONOMICAL, safer, more uptime, faster. The clouds have been around for a decade or more and how many banks have transitioned to the public cloud from a mainframe?

Re: AWS is down.
1 mic, 4 mics, 40 mics, 400 mics is all irrelevant to the original topic. AWS was down for hours, longer for some. Important transactions just can’t be unavailable for hours and that’s why banks, health care, insurance, airlines, big retail, and others will never leave the mainframe.

Re: AWS Outage Analysis: December 7, 2021
Of course... military has the money (the $500 hammer?) to have redundancy on their redundancy. Business installations normally can't justify those costs. However, I think if we looked close we both might be surprised at all the various baskets AWS has behind the scenes. But like any basket collection, there are always single points of failure.

Re: AWS is down.
I've not seen 4 mics, maybe less than 100 But I've not done any serious looking. My numbers, 5 mills to 400 mics was a quick overview to grab averages. Once I saw the numbers I knew there would be performance gains since my workloads are mostly, I would like to think, of fairly normal profile, weighted more heavily on IO than the other resources. And I did see movement graphically with backup windows, for one, moving back in time but did not do any further discoveries.Sent from my Verizon, Samsung Galaxy smartphone Original message From: Ronald Wells <02ebc63ff5ef-dmarc-requ...@listserv.ua.edu> Date: 12/8/21 9:09 PM (GMT-05:00) To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: AWS is down.

Re: AWS Outage Analysis: December 7, 2021
Pretty damning if you ask me... https://aws.amazon.com/message/12721/ "At 7:30 AM PST, an automated activity to scale capacity of one of the AWS services hosted in the main AWS network triggered an unexpected behavior from a large number of clients inside the internal network. This resulted in a large surge of connection activity that overwhelmed the networking devices between the internal network and the main AWS network, resulting in delays for communication between these networks. These delays increased latency and errors for services communicating between these networks, resulting in even more connection attempts and retries. This led to persistent congestion and performance issues on the devices connecting the two networks." We didnt test our software fully before deployment, and got bitten by a situation we didnt test for. And Bezos wants us to trust this to put people in space?
