Cosmos DB
  •  Can be used with Serverless Computing
  • Globally Distributed
  • Elastic
  • Various regions
  • Can also scale storage
  • Can use SQL API
  • Enterprise ready
 The High availability helps web, gaming, IoT, and mobile 

Data Lake

  •  Enterprise
  • Big Data
  • Storing all Sorts of Data
  • Integrates with data warehouses
  • Processing
  • Analytics
  • Pay per job
  • Instant Scale
  • Used for things like
    • Xbox Live
    • Office 365
    • Skype
    • Big

SQL Database

  •  Can import data from there to Classic Machine Studio
  • Current Operational
  • Normalized Relational
  • Max Capacity is 4 TB
  • Always on by design
    • Create
    • Retrive
    • Update
    • Delete
  • Query Limit - 6400
  • Machine Learning built in (See: Azure Machine Learning Service, and Azure Machine Learning Studio Classic)

SQL Data Warehouse
  • For external data, historical operational
  • Denormalized (into larger table [notes unclear])
  • Near unlimited storage with 240 TB
  • Paused post analysis
  • Limited number of uses
  • Query Limit - 32

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

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 intruder, but it is a step. There are no devices associated with this new server; In an earlier lab (not shown), I attached them to 'H

Create a Simple Network (Packet Tracer) + A Walkthrough

Again; I've done this, but now there's so many new things, I'm doing it again. The truly new portions were...everything on the right side of this diagram; The cloud needed a coax connector and a copper Ethernet connector. It's all easy to install, turn off the cloud (Weird), install the modules. Getting the Cable section of Connections was an unusual struggle - The other drop down menu had nothing within. It required going into the Ethernet options and setting the Provider Network to 'cable', which is the next step AFTER the drop-downs. The rest was typical DHCP and DNS setups, mainly on the Cisco server down there. The post is rather short - How about adding a video to it? Find out what A Record means - This site says 'Maps a name to an IP address', which is DNS. So it's another name for DNS? You can change them (presumably in a local context) to associate an IP address to another name.

Securing Terraform and You Part 1 -- rego, Tfsec, and Terrascan

9/20: The open source version of Terraform is now  OpenTofu     Sometimes, I write articles even when things don't work. It's about showing a learning process.  Using IaC means consistency, and one thing you don't want to do is have 5 open S3 buckets on AWS that anyone on the internet can reach.  That's where tools such as Terrascan and Tfsec come in, where we can make our own policies and rules to be checked against our code before we init.  As this was contract work, I can't show you the exact code used, but I can tell you that this blog post by Cesar Rodriguez of Cloud Security Musings was quite helpful, as well as this one by Chris Ayers . The issue is using Rego; I found a cool VS Code Extension; Terrascan Rego Editor , as well as several courses on Styra Academy; Policy Authoring and Policy Essentials . The big issue was figuring out how to tell Terrascan to follow a certain policy; I made it, put it in a directory, and ran the program while in that directory
