Deploying and Managing Scalable, Cloud-Based Infrastructure in Azure

This blog post is located over here; Managing Scalable Azure Infrastructure 

 

Here are my notes while the above portfolio is being restored; I...accidentally deleted it while mass cleaning out my Drive and didn't realize for a week. Oops. If anyone has a contact at Google who would like to help, I'm on LinkedIn.

 They're messy, but the gold shines through.

In Summary (Load Balancing and maintenance);

I created two azure load balancers for web app redundancy and speed; this eliminates single points of failure. Health probes let me know if something needs attention. 

Distributes web traffic across multiple virtual machines, making it resilient + scalable, maintain performance, and eliminate single points of failure.


A health probe makes sure everything is up and operational, and LB rules distribute HTTP traffic.


Hands-on experience configuring 2 azure load balancers, a tool that, at it’s base basicness, has multiple components that ensure uptime, optimize web traffic, and improve application reliability.


Optimized web traffic and ensured application uptime and reliability by configuring 2 azure load balancers and health probes across multiple service regions that maintain performance by eliminating single points of failure. 


Testing Load Balancers

In Summary - 

After I set up the LBs, I tested load balancers in two regions to ensure uptime and redundancy [by stopping and starting virtual machines [simulated a failure] to watch the data carry over to the other machine]

 

Ensure IPs are static.


Configuring static IP addresses for the load balancers. Other devices like laptops or phones do not have static IPs because of [lot of jargon/reasons you could pay me to go into], but we want our load balancer VMs to be firm and in place.


Also, less admin overhead for us.


We want scalable and fault tolerate infrastructure! Dynamic IPs means our LB VMs aren’t secure.


 

First, what is Internet Information Services?

It’s a Microsoft Web Server tool to serve HTML (web) pages. If you’ve never heard of it, nor me until I did this. 


I install it onto a VM using the Powershell command so we don’t expose the virtual machine to the greater internet unnecessarily. It's more secure this way!

 

What happens to make sure if one aspect goes down? We need redundancy (The irony of me typing this, this entire post, because I accidentally deleted my Google Site where the original information is.)

 

 We use Blob Replication;

  • Between storage accounts (and I guess those storage accounts can cross regions if they’re attached to it. 

  • Updates in primary storage are copied to secondary account

  • Supports disaster recovery, fault tolerance, and content synch

  • If you replicate it, if something goes down, then it’s somewhere else

 Also ties in with a Content Delivery Network (CDN) - it delivers the assets to the visitor.

 

I then mapped CNAME and URL records to the proper URL (Again, the irony is not lost on me, as I did that 10 minutes before writing this post as I accidentally deleted my Google Site where the original information is from both Sites and Trash!)

Making KPI Dashboards with PowerBI

 While this is the free tier, I cannot share or collaborate with others, nor can I publish content to other people's workspaces, but they will not stop me from screenshooting and recording these self-taught adventures,so! I'm doing this because I idly searched "Mattel careers" and "Information Technology", and seeing a bulletpoint saying the following: Analytical and reporting skills such as creating dashboards and establishing KPIs such as experience with PowerBI, Cognos, Tableau, and Google Data Lake/AWS is preferred And thought "Well, I've used Tableau, and I've heard about PowerBI,  even if its in-demandness is questionable , so how similar is it? And can I write about it?"  First, PowerBI (PIB) does have a downloadable, local version, but apparently Windows-only. I could download the .exe but I couldn't run it / drag it to applications on my MacBook.  Not a problem, we'll use the online SaaS version, and a dataset found here, ...

Connecting IoT Devices to a Registration Server (Packet Tracer, Cisco)

 If you're seeing this post, I'm helping you, and you probably have LI presence: React and share this post to help me in return.   In Packet Tracer, a demo software made by Cisco Systems. It certainly has changed a lot since 2016. It's almost an Olympic feat to even get started with it now, but it does look snazzy. This is for the new CCNA, that integrates, among other things, IoT and Automation, which I've worked on here before. Instructions here . I don't know if this is an aspect of "Let's make sure people are paying attention and not simply following blindly", or an oversight - The instructions indicate a Meraki Server, when a regular one is the working option here. I have to enable the IoT service on this server. Also, we assign the server an IPv4 address from a DHCP pool instead of giving it a static one. For something that handles our IoT business, perhaps that's safer; Getting a new IPv4 address every week or so is a minimal step against an...

AWS Infrastructure Composer

 A very brief look. The text says; Drag and drop any CloudFormation resource on a visual canvas Connect and configure enhanced components to automatically build IaC for an application architecture Seamlessly transition between authoring workflows visually with Step Functions Workflow Studio and defining resources with Infrastructure Composer Integrate your browser with your project through “local sync” or use Composer in the AWS Toolkit for Visual Studio Code In 2019 there was a similar tool to build infrastructure that would be converted to code. Nice to know they bought it back. When you enter the Composer, it's a blank space with a background reminiscent to the screen for Cloud Formation. Infrastructure Objects are to the left in a drawer;  I've selected a bucket that I can rename. I went to connect a bucket to a Dynamo DB Table, and it's not available yet. It also lost a bucket somewhere in the ether of the GUI. Ah well. I couldn't find the EC2 instance in the...
