Azure Dublin Meetu
Hugo Barona Elkhan Yusubov

Meet Sam .
Sam has around 10 years
of experience in IT as a
SysAdmin + IT Operator.
Sam recently completed 3
cloud certification exams.

With his newfound cloud
knowledge , Sam attends a
Cloud Architecture
interview for a prestigious
IT firm .

Unfortunately , the interview
does not go well . He is asked
about topics he had not
encountered in the cloud
certification exams ,and
as a result -
he gets rejected .

Meet Stephanie .
She works as a Lead
Developer in an IT
company.
She has developed quite a
few products using cloud
services.

She is asked to take over
the role of a Cloud
Architect for a large-scale
application which will be
published across the
enterprise.

She delivers the product , but it
is neither scalable ,nor resilient
enough , even though she is a
great coder , and had put the
best programming standards in
place .
She loses the trust of the client
and as a consequence , her
manager.

So , the million $ question is –
1 . What went wrong ?
2 . What did they (particularly) do wrong
?
3 . How can I/you prevent myself/ourself
from doing the same mistakes?

Let me (briefly) introduce myself -

Currently , an Assistant Director,
Cloud Practice at EY (Ernst & Young).
Before that I led the CCOE ( Cloud
Centre Of Excellence Team ) at Accenture.
Have 10+ years of IT experience , working on
Cloud since 2017.
But , most importantly (and I want to
focus on this for a minute) , I successfully transitioned
my career
from being a C#,SQL developer
to a CSA(Cloud Solution Architect).

What happened in 2017-2018 ?
1 . Realization that I needed to
transition to something else ( Most
important).
2 . I documented my purpose / future
goals clearly.
3 . Then , I took appropriate steps to
enable my cloud journey.

I want to help you do the same , in case
you guys are interested in making
this transition !!

It doesn’t necessarily matter who you are right now -

All you need to do is
START !
Ref - https://www.youtube.com/watch?v=F2pXoh3Cmo8

I will try to leave 5-10 minutes at the
end to address any queries you might
have on this topic.
So , you can ask the questions on chat .
If I cannot answer them during the session
I promise , I will personally reach out to you ,
and answer them later.

Overall Agenda (Part I , 2 and 3 ) -

Before ,we get into how to
become a cloud architect ,
we need to first understand
the basics.
Note –
Getting the basics right is very important.
In this ever-changing landscape of myriad technologies , it
is only possible to stay relevant , if you understand the
foundation topics well .
The trick to note here is that the fundamentals / basics
have not changed that much over the years.
They have (kind of) stood the test of time .
Today there is Kubernetes tomorrow there will be
something else , but the essence will stay the same (
mostly ).

If we do not start with the basics
there is a high chance that ,
we will fall into one of the 2
scenarios that I mentioned at the
start of the presentation.

Ok , but what is architecture ?

IEEE 1471:2000 definition -
‘’The fundamental organization of a system embodied
in its components, their relationships to each other,
and to the environment, and the principles guiding
its design and evolution.’’

Grady Booch , IBM Fellow
“architecture represents the set of
significant design decisions that shape
the structure and behaviour
of a system where significance
is measured by cost of change.’’
Ref - https://twitter.com/grady_booch/status/1257355498598342656?lang=en

Martin Fowler
https://www.youtube.com/watch?v=DngAZyWMGR0
“the set of design decisions
that must be made early”
What is architecture ?

Matthew Parker , previously Global Head
of engineering – Pivotal Labs
“Architecture , in the field of
software development ,
are decisions that are hard to reverse ”

Some examples could be -
“Whether to deploy our application on container based
compute environment like Kubernetes or go with
a serverless model like AWS Lambda? ”
“Whether to go with synchronous API-based
communication or use a event-bus based asynchronous
messaging system like RabbitMQ/AWS SQS? ”
OR
OR
“What programming language do you use for your
application development? ”

Ok , then who/what are architects ?

“Architects have a holistic understanding
of the system , across a different spectrum
of views and viewpoints , and they offer a
different perspective of the
system/design.”

“The architect doesn’t have
to be the smartest
person in the room.
Instead they make
everyone else smarter.”
Gregor Hohpe ,
Enterprise Strategist , AWS
https://architectelevator.com/architecture/multiple-dimensions/

Architecture matters -
“Bad architecture / no architecture slows down the ability of our customers to compete , as over time it becomes
harder and harder to ship new features”

https://martinfowler.com/bliki/DesignStaminaHypothesis.html
Let me explain ,

Ref - https://betterprogramming.pub/agile-
architecture-intent-vs-the-immediate-36d327289b2d
Agile architecture - Immediate Architecture to
Architecture Intent

But , what does this have to
do with me ?
Why do I (personally) care about
software/cloud architecture ?
Why would I want to become a Cloud
Architect?

https://info.flexera.com/CM-REPORT-State-of-the-Cloud
“Almost all organizations are using at least one cloud”
Reason 1 – Cloud adoption is increasing

https://info.flexera.com/CM-REPORT-State-of-the-Cloud
Reason 2 – Companies are spending
money on cloud

Reason 3 - Because , a 2020 survey by
the Job
search engine Indeed says – “Software
Architect is the best job ”
Look around you , you will see
that architects are typically
paid 5-10x , the salary
of standalone engineers/developers.

Cloud architecture is the way technology components combine to build a cloud,
in which resources are pooled through
virtualization technology and shared across a network.
The components of a cloud architecture include:
• A front-end platform (the client or device used to access the cloud)
• A back-end platform (servers and storage)
• A cloud-based delivery model
• A network

If I had to define Cloud Architecture , or focus on a part of it , that makes the most sense to me , is to go with
the below analogy -
Pets Vs Cattle – At a high-level , if you understand this
you understand the basics of cloud architecture

Your implementation of these architectural
attributes might vary from use-case to use-case , but
If you can ensure that your architecture
respects this set of constraints , then you can confidently
claim that you have created a “well-architected design”

Noticed something ?
Essentially , even in the cloud,
nothing has changed that much .
All the constraints / quality
attributes that you
needed to maintain in your datacenter
based applications are relevant even now ,
more so than ever .

Moving / migrating to the cloud , does not
mean that you do not need to think about
Scalability any more .
The same constraints are present in the cloud also ,
but the toolchain available is more robust and
easy-to-consume.

Even at a high-level , the AWS WAF ( Well-Architected
Framework ) emphasizes the same NFR(s)

The cloud might
be new , but the
essence of
architecture
remains the
same .

Essentially , the attributes that public cloud offer , for
example – infinite compute , pay as you go offering and
so on , helps architects in building solutions that
respect the quality attributes we discussed before .
Cloud Platforms / Cloud Service
Providers (AWS, Azure, GCP) help
architects in building better
solutions.

And these are
called – Non
Functional
Requirements

Normally , in architecture design , there
are different types of requirements
• Functional
• UI
• Business/Domain
• Non-Functional (NFR)

Being a cloud architect , you should
focus on documenting , defining ,
implementing and managing the NFR(s)
of the system you are designing.
Typically , these will be documented in SADs (
Solution Architecture Documents )

Quite frankly , architecture is more complicated -
But , it is better to get started with the quantifiable
ones ..

“CLOUD-NATIVE = LOOSELY COUPLED
RUNNING IN THE CLOUD”
“Cloud is where you compute ,
Cloud-native is how you compute”
Ref - https://www.youtube.com/watch?v=VpZHLtu8mj0&t=1045s

Principles of Cloud-native architectures
https://www.ibm.com/cloud/architecture/architecture/practices/cloud-native-principles/

“At a high-level , if you really think about it ,
Cloud native architecture principles
are just extensions of the best practices/standards
that enforces the same NFR(s)
that we discussed”

Let’s take an example –
One of the key principles of cloud native architectures
is immutability .
This means that the infrastructure is not modified in
place after deployment .
This means that we must have an automated way of
creating
a new instance of an application .
This means that if our existing application is down , we can
quickly create a new instance.
This means my application is (as a consequence) RELIABLE

So , simply put cloud-native application
architectures are a way to build better applications
that work better , scale better , are more reliable ,
take full advantage of the cloud , provided
you play by the rules .

The last part is very important – you need to play by the
rules .
Cloud service providers like AWS ,Azure OR cloud native
platforms like Kubernetes , VMWare Tanzu are here
to help , but you still need to architect your
system correctly.
And that is where cloud architects come into play.

Cloud-native is an approach to
build & run applications that can
leverage the advantages of the
cloud computing model.
In a nutshell ,

Cloud native is a big topic , stretching across a lot
of components -

Okay , let’s take a step back
and look at what we covered till now .

I spent a lot of time on the basics in Part 1 ,
so that I can leverage this foundation
to concentrate on actual guidelines on how
you can start your journey in Parts 2 and 3.

There is no shortcut
to becoming a cloud
architect.
You need to spend
the required time ,
and effort .

So , coming back to the question we
started with at the beginning –
1 . What went wrong ?
2 . What did they do wrong ?
3 . How can I/you prevent myself/ourself
from doing the same mistakes?

Scenario 1 ( Sam ) – Needs to understand
how architecture is important , and how
to design applications that respect the
NFR(s) to get a Cloud architect role ; only
certifications are not enough !

Scenario 2 ( Stephanie ) – Only
programming/having a limited
perspective of a system will not help in
large-scale enterprise architecture.
Having a holistic view is equally
important , if not more.

SNEAK PEEK INTO PART 2 -
• We will discuss actual actionable steps
to enable your cloud journey.
• Will go over 10 concrete actions that
helped me in my journey when starting.
• Discuss tips & tricks to stay focused ,
and not get overwhelmed with the
abundance of knowledge available in
the market today.
