 ## Why?
 
 You should learn more "advanced" DevOps if:
 
-+ You / your team have "out-grown"
-[Heroku](https://github.com/dwyl/learn-heroku)
-(_e.g: your Heroku bill is more than $100/month_)
-+ You want "more control" over your infrastructure
-e.g: to run a specific version of software or database.
-+ Your client/boss has instructed you
-to use a _specific_ "cloud" provider.
-+ Curiosity to extend your
-"back end infrastructure" knowledge to be a more
-"well-rounded" developer.

 ## How?
 
 Over the years we @dwyl have deployed/managed Apps,
 both our own and those of our clients,
 on a wide variety of infrastructure and platform providers.
 
 _Most_ of our Apps have been deployed to **Amazon Web Services** ("**AWS**")

 ### Using a Different Cloud Infrastructure Provider?

 we @dwyl have _experience_ of using _several_ infrastructure providers:

+# Fly.io
+

+is a new type of Platform-as-a-Service (PaaS)
+for deploying web Apps/APIs
+closer to the people _using_ them.
+Much like a 
+[Content Delivery Network](https://en.wikipedia.org/wiki/Content_delivery_network)
+(CDN)
+where there are copies of your `static` content 
+stored on "edge" nodes close to the people (devices)
+_consuming_ the content,
+Fly.io replicates your Application
+so that it is closer to the people _using_ it.
+
+## Why?
+
+On the surface it looks like a _great_ way to deploy Elixir/Phoenix Apps
+and they are committed to making the experience great.
+
+
+
+## What?
+
+A new way of deploying Elixir/Phoenix apps that will continue to get better because they

+(creator of Phoenix!!) 
+
+## Pricing?
+
+Pricing seems "_fair_", or at least _comparable_ to AWS.
+See: [learn-devops/issues/72][https://github.com/dwyl/learn-devops/issues/72#issuecomment-945001230]
+
+
+### Venture Capital (VC) Funding?
+
+Fly.io are funded by 
+[YCombinator and a few others](https://www.crunchbase.com/organization/fly-io/company_financials)
+Obviously we would _prefer_ if they were independent,
+but we totally understand that 
+building this kind of service requires considerable capital investment
+in the form of both infrastructure and engineers.
+
+I suspect they are piggy-backing on AWS/GCP/etc 
+rather than running their own servers.
+But they still have the job of making it all seamless.
+
+<br />
+
+# How?
+
+Following the "_Hands on with Fly_" (getting started guide):
+https://fly.io/docs/hands-on/start/
+
+## Instal `flyctl` CLI
+
+https://fly.io/docs/hands-on/installing/
+
+I'm using homebrew on mac so:
+
+```sh
+brew install superfly/tap/flyctl
+```
+
+## Deploy an App
+
+Followed: https://fly.io/docs/getting-started/elixir/ <br />
+Created the PR for deploying Hits to Fly.io: https://github.com/dwyl/hits/pull/128 (detailed log in the PR)<br />
+
+
+The process for deploying a Phoenix App was a bit _long_ ... ⏳ (_lots of steps..._)<br />
+But the docs were good and when I got stuck their forum was useful.
+
+## Metrics UI
+
+The Fly.io web interface is still _very_ basic: https://fly.io/apps/hits/metrics?range=172800
+![fly-hits-app-metrics-http](https://user-images.githubusercontent.com/194400/140039296-ed327b71-3202-40da-ba7e-33f53bf531b1.png)

+
+# Conclusion
+
+Fly.io seems to be good so far.
+My plan is to check-in with the Hits App on Fly on a weekly basis and see how it's doing.
+Right now I'm just stoked that it's working and has fast response times.
