When do you need to use some form of Cloud Distribution?
If you consider this concept a form of caching, then you need it when your website passes a certain threshold in terms of users and the volume of data that is being sent out. The actual numeric figure depends entirely on your setup – you may have large files and sending them out of your server may fill up the available bandwidth. Or you may have a lot of users and may want to ease the load on the server by pushing some of this load to somewhere else.
Nevertheless, the purpose of this article is to show you how this is being done by using the AWS CloudFront.
AWS CloudFront
First, you need to go to the “CloudFront” option in the AWS Console and attempt to create a Web distribution. On the creation page you should first fill in your domain name as the distribution origin (the primary source of the content):
Starting from today I am one of the AWS CSA(A) certified professionals. The license number is generated sequentially so it is easy to infer that I am the the 16.891st person on this planet holding the title, but given the 2 year recertification cycle I assume that many of those who were certified before may have not renewed their certification status.
Starting on the path
I have registered my own private AWS account in the second part of 2014, around the time when I was assigned to the project I have talked about in the previous text. I did not make much of that account and still do not use it for more than cloud backups; without a professional motivator, getting on this path will not truly bring anyone very far.
The game changer was the DevOps work I have started doing for a customer of my employer: they had a fully configured AWS environment I was given access to. The year Amazon suggests you to spend in a professional environment before trying to get certified is by no means a spurious requirement; there is an entire ecosystem that needs to be mastered in order to make the best use of it.
Preparation
The certification adventure started about a month ago by reading this Reddit post. I didn’t get the free full month of study on offer due to the timezone difference but the seed got planted. What happened next?
More than a year ago, during a time when I barely knew anything about Cloud Computing or AWS, I was assigned along with a couple of colleagues on bringing an existing code base from “alpha” to “production” and ensure a smooth deployment to the Amazon Cloud. The customer wanted to “go live” in less than 3 months and be able to handle tens of thousands of visitors that would click on banners and fill their bank accounts; well, most likely they were just wishing for a good exit. On a side note, one of the photoplasty sections of the cracked.com website has an image about this type of business.
Starting the project
Things initially went to some direction – we dealt with many functionality issues, being able to fix and test more than 100 bugs and glitches; after all, this was the thing we knew best how to do and we also put in the long hours required for getting things done. We weren’t bothered by the cloud setup issues – the customer fiercely guarded the “keys to the kingdom” and agreed on instance and resource set-ups on a case-by-case basis only, all with the desire of keeping the Amazon bill as low as possible. We thought this was fine – it was their home, they knew best what they needed.
