Meta-blogging



Meta-blogging, a bit like Klein-bottles? (one sided surfaces, not possible in the real world, but models are still made, see image above).

Blogging about blogging (which could lead to infinite recursion).

Here's my 1st official Instaclustr Technology Evangelism blog post!

Chapter 11: AWS Directory Service, Cloud Directory

"Name or Number please?" So the 1st telephones systems were point to point, and then hub and spoke. You rang the local exchange, asked to talk to Auntie Jill and the "operator" (think the Matrix) would ring Auntie Jill's phone and connect you (literally with a patch cord) once Auntie Jill had answered. If you wanted to talk to someone not on the local network the operator would call another operator (how did they know which one?) and ask to them to connect and you would eventually get patched through. This was even more fun if you wanted to ring someone overseas, as you would hear the patchwork of operators, some speaking foreign languages (what fun), the the sounds getting fainter and weirder (lots of clicks, "undersea" sound effects like talking down a tube, echos, etc) until finally you heard Auntie Jill's voice saying "hello?" and you could talk to them (which was expensive, and the operators would sometimes break in and say

AWS Solution Architecture Certification Postscript

So I sat the exam today and past ok yippee. Guess there's no need to continue blogging about AWS certification stuff!? The AWS Certified Solutions Architect – Associate exam is intended for individuals with experience designing distributed applications and systems on the AWS platform. Some general observations. The real exam is somewhat harder than the practice tests and practice exam (about 10% harder?) NONE of the practice test questions appear in the real exam. The focus is only what I would call the legacy IaaS Amazon services. Almost no questions on managed services, Machine Learning, Data Analytics, Lambda, etc. Lots of questions on what I would call systems and networks admin stuff.  I spent a few months trying to learn this stuff but actually I don't think it helped, I'm not sure I got any of these questions right. E.g. the sort of qns were if you have this sort of set up (VPCs, subnets, ACLs, groups, EC2, etc) and this doesn

Chapter 2: Amazon Simple Storage Service (S3) and Amazon Glacier Storage (for storing your beer?)

Chapter 2: Amazon Simple Storage Service (Amazon S3) and Amazon Glacier Storage The Amazon Glacier Storage Service is designed for cheap long term archival storage, so you want things to stay put in it for a long time. It is a slightly odd choice of name these days given that global warming is a significant threat to Glaciers (Glaciers are "shrinking" and large dangerous chunks are falling off them as in the above image of the warning signs at a famous New Zealand Glacier (Franz Josef Glacier).  Maybe the Amazon "Glaciers" will be the only ones still around in a few 100 years. I initially found it "odd" that the AWS Solutions Architect Certification book introduced storage services before compute services.  However, in hindsight this sort of makes sense as S3 is one of the original services, is core to other services, and introduces many of the AWS concepts, and is a "managed" service so it simpler and more typical in some respects.
