AWS Cloud Computing Concepts and Tech Analogies

Understanding Cloud Computing – Demystifying the Cloud

The alarm clock goes off… and Alex prepares for a new day. A special, different day, as he is starting his first job as a cloud engineer at TRENDYCORP.

As he’s riding his bike to the main office, he feels a strong rush of memories from the last few years. Four courses at university learning about computer science, a short course on programming macros in Excel, some months looking for a first job, mixed with several crazy parties and holidays, and finally, this offer from TRENDYCORP. He honestly couldn’t figure out why he was hired. He has no experience with the cloud, but this company seemed really interested in it.

The usual first-day steps are taken: signing in at reception, security guards taking a picture for the ID badge, taking the picture again because he doesn’t like how it looks, getting a new laptop with all the software preinstalled, connecting to the intranet, and waiting for the initial meeting.

Finally, Alex is pushed into a small room, where some other people are already gathered around a big table. Yes, these tables always seem bigger than the room. While Alex finds the only empty seat, a serious-looking woman stands up and begins to talk:

Description automatically generatedEva: Welcome to TRENDYCORP. My name is Eva and I’m the HR manager who hired most of you. Alex, please sit down immediately. TRENDYCORP, as you all should know by now, wants to continue to be the leader in the Filiburths market – and for that, we have to modernize most of our old-fashioned processes, change most of our technology, and move to the cloud. That is the key – the cloud. To be honest, all I know about the cloud is... well, that’s where rain is produced, but as all our competitors have decided to go for it, we’ll do the same. And that’s why many of you were hired; we have to move to the cloud, and I want it yesterday!

She makes a sign to the young woman sitting beside her, who stands up.

Description automatically generatedGloria: Welcome, all of you. I hope you’ll feel comfortable here. My name is Gloria, and I’m the manager of this IT team. First, I’d like to welcome Alex, Berta, and Raj, who are joining the team today. As it is their first day, I’ll ask everybody to introduce themselves – but first of all, some technical context for all of you. As Eva said, we have to migrate all our servers to the cloud. I’ve recently taken some training from our cloud provider, something called Cloud Essentials, and I think I have an initial idea of how we should proceed – but of course, I’ll need all your collective experience to help us move our projects to the cloud. That said, let’s go with your introductions.

Description automatically generatedAlex: I’m Alex. It’s my first day here. I’ve just finished my IT studies at university. Lots of theoretical things, but I have no real working experience. As for this cloud thing, I imagine it’s that place where you store your personal photos.

A picture containing text

Description automatically generatedBerta: Hello, this is Berta. Like Alex, it’s also my first day. I’ve worked in several companies, some of them our competitors, as a developer and database administrator, for more than 7 years. I can query you using different SQL dialects, in multiple languages. I have also done some basic training on the cloud and read some documents, but I hope I can learn more and be useful to the team.

A picture containing text, arch

Description automatically generatedRaj: I’m Raj. Like Alex and Berta, it’s my first day here. I know a bit about networking, protocols… in general, communicating between multiple networks no matter where they are. As for the cloud, I’ve got a collection of scripts to download files; I hope they can be useful.

Charles: I’m Charles. I’ve been in TRENDYCORP for many years, maybe more than 10, and am in charge of network security. Other employees call me Change-No-Rules Charly. I’ll, of course, help you with every technical aspect you might encounter, but it has to be related to cables, routers, and firewalls. I’ll probably ask you lots of questions about that cloud thing. I imagine you studied it at university, didn’t you?

A picture containing text, clipart

Description automatically generatedDavid: My name is David. I don’t work directly for TRENDYCORP; I’m your technical contact for my company BrandXCloud. We are specialized in cloud migrations. We have a team of cloud experts working for you, so if you need any technical help, please describe your issue accurately, send it to me, and I’ll forward it to the right person.

Harold: I’m Harold. I’ve been in this company for more than 20 years, in all of the important projects. If you need help, tell me, but only if I’m not busy with some tasks. I like discussing solutions, not problems. Over.

After the introduction, Gloria presents a list of applications they run at TRENDYCORP, and it mostly devolves into a conversation between David and her. Everyone slowly fades away, and soon the meeting ends.

What is cloud computing?

Alex and Berta return to their desks after the meeting. They see Gloria rushing to the meeting room. Gloria is nervous, as it is her first presentation to the TRENDYCORP board about the cloud. Most of the board members are traditional businessmen and have very little to do with technology. She has rehearsed the presentation but still has butterflies in her stomach. She is expecting a lot of WHY and WHAT questions. Finally, everyone arrives on time and the presentation starts.

A picture containing text, light

Description automatically generatedGloria: Thank you everyone for making the time to be here. I am happy to walk you through the benefits we plan to achieve by migrating to the cloud. First, I will walk you through the current model of IT at TRENDYCORP, and later, I will talk about how cloud technologies can help us.

Gloria moves to the first slide on the screen:

A picture containing text, light

Description automatically generatedGloria: So currently, we are running some of our IT and business applications from this room. It is our data center and…

Before she can finish her sentence, a question is raised.

Board Member 2: Which applications?

A picture containing text, light

Description automatically generatedGloria: We have around 20 applications running here; some notable ones are our internal website, the invoicing system, inventory management system, payroll application, email servers, and some monitoring applications.

Board Member 2: Where are the rest?

She moves to the next slide and the picture looks similar but much bigger and tidier:

Figure 1.3 – The shared data center

A picture containing text, light

Description automatically generatedGloria Those are being run from a shared data center we have on the outskirts of the town.

Board Member 1: I didn’t know that… but anyway, please proceed.

A picture containing text, light

Description automatically generatedGloria: So, currently, our applications are split across three locations; one is our own server room, the second is the third-party data center on the city outskirts, and the third is the leased data center near our manufacturing plant in Asia. We have a leased line network connection connecting these three locations so that our developers, who work from this office, can access and connect to the remote locations. As our business is growing at a rapid pace, the need to scale and operate our applications at the same pace is becoming a challenge. Over the past three years, our online business has surpassed traditional methods, and we have a growing customer base that is keeping our software development team busier than ever. I have put together some data points related to growth, budget, and estimations for the next two years in a printed report, which is in front of you.

All the board members open their folders and start browsing through them. Gloria takes a deep breath and drinks some water to soothe her nerves. As everyone is checking the report, the room is filled with an awkward silence. This goes on for a few minutes.

Board Member 3: If I read your estimates correctly, you are saying that we are already running 120% of the planned capacity for our IT needs.

A picture containing text, light

Description automatically generatedGloria: Yes, that’s true, and that is adding pressure to our overall online portfolio. On the one hand, we are running at a higher-than-estimated consumption of our applications, and on the other hand, our incident response time and the number of major incidents are increasing.

Board Member 3: Major incidents?

A picture containing text, light

Description automatically generatedGloria: A major incident is a highest-impact, highest-urgency incident. It affects a large number of users, depriving the business of one or more crucial services.

Board Member 3: Obviously, this is not good for business. Do we lose business when this happens?

A picture containing text, light

Description automatically generatedGloria: Yes, we do. Those numbers are on page 5.

Board Member 3: That’s alarming – and you mean to say we can address this by using the cloud?

A picture containing text, light

Description automatically generatedGloria: It may not happen overnight, but surely, it will be the right step – because if we keep going with the current model, we will be adding to the problem rather than solving it.

Board Member 3: So, this cloud will only solve current problems, or do we need to find some other solution for forthcoming problems?

A picture containing text, light

Description automatically generatedGloria: There are some additional advantages of using the cloud, and that’s what I want to discuss next.

Board Member 3 nods his head.

A picture containing text, light

Description automatically generatedGloria: Okay, so if there aren’t any further questions, I want to present the six major benefits of moving to the cloud.

She moves on to the next slide:

Figure 1.4 – Benefits of the cloud

Figure 1.4 – Benefits of the cloud

A picture containing text, light

Description automatically generatedGloria: Currently, for every new project or capacity expansion in an existing project, we have to make a large capital expense. This includes an expense in terms of buying new servers, adding more storage, upgrading our internet, and more. Whereas with the cloud, we don’t have to make any capital expenses, we can use the cloud like a utility, as with electricity, and we pay only the usage charges, which are based on what we use. This model will allow us to trade capital expenses for variable expenses.

Board Member 2: Will it result in cost savings or just the same capital expense spread over in shorter chunks?

A picture containing text, light

Description automatically generatedGloria: We plan to achieve cost savings. I have added that estimation on page 8.

Board Member 2: A quick question: won’t these services be at a higher cost? Don’t we need to take the profit for the cloud provider into account? When I make a meal at home, it is obviously cheaper than having a meal in a restaurant.

A picture containing text, light

Description automatically generatedGloria: In the case of cookery, that is true, but in the case of cloud services, the answer is different. That’s the second benefit.

She moves to the next slide and explains:

Figure 1.5 – Economies of scale

Figure 1.5 – Economies of scale

A picture containing text, light

Description automatically generatedGloria: Cloud providers benefit from economies of scale. As an example, when one of our customers buys one product, they pay X amount, but when our dealers place an order of the same product in bulk quantity, they get a volume discount. Similarly, cloud providers buy in bulk, negotiate better contracts from hardware manufacturers, power providers, and real-estate companies, and keep their own cost low. This is translated into lower costs for the customer, and if the costs are lower, more customers will use their services, which results in the overall cost of services becoming lower. Some cloud providers get their hardware highly customized as per their requirements and cut down on the cost of things that they do not need. This results in a much lower price for customers.

Board Member 1: That’s an interesting way of doing business.

A picture containing text, light

Description automatically generatedGloria: As another benefit, we, as the customer, don’t have to worry about capacity. Currently, for every project, we launch or expand; we make a capacity estimation and buy resources based on these estimates – and if these estimates are wrong, we lose money or lose customers.

Board Member 1: Can you explain this?

A picture containing text, light

Description automatically generatedGloria: Let’s say our team estimates that for project X, we will need 10 resources. This is based on an estimation of 1,000 customers using that application. If the application is popular and we have more customers than estimated, then the 10 resources may not have enough capacity to handle the increased load and our customers will get a slower response from the application, which results in unsatisfied customers, and we may lose them if this is persistent. Conversely, if the utilization of resources is lower than the estimation, let’s say only 4 resources are being used because of less customer demand or a slow sales quarter, we are keeping those extra 6 resources running – and it costs us money to keep those unused resources running.

Board Member 2: Can somebody not shut down those resources?

A picture containing text, light

Description automatically generatedGloria: Yes, we do so, but that only saves the running cost, as with electricity and cooling, but the capital expense of buying that resource is not reversible. And after a finite lifetime—in most cases, it is 2 or 3 years—the resource will no longer be supported and we will have to buy support plans separately, which leads to the maintenance cost of older resources increasing. It is similar to how maintaining a very old car can become expensive as those parts are not in production anymore.

Board Member 2: So, we call the cloud provider to shut down those resources and start them again when we need them?

A picture containing text, light

Description automatically generatedGloria: Not exactly. We don’t need any human intervention for it. It is all programmable and sometimes built into the offering of the cloud provider, so we no longer have to guess the capacity for every project. We can start small and then shrink or expand the resources as needed.

Board Member 2: Okay.

A picture containing text, light

Description automatically generatedGloria: Also, since these resources are available on demand, we don’t have to go through lengthy procurement cycles, which sometimes take months. We can roll out new features more quickly, run multiple campaigns in parallel, compare their performance, and respond quickly to changing demands. This will increase the speed and agility of our IT team. We will be able to experiment more often, run more proofs-of-concept, and never worry about the high cost of failure, as in traditional systems.

Board Member 2: So, what will happen to the engineers we have on 24/7 support? Will this cloud leave them without a job?

A picture containing text, light

Description automatically generatedGloria: No. It will just change their focus. Currently, they are mostly in fire-fighting mode. They are always busy with undifferentiated heavy-lifting tasks, such as troubleshooting, capacity expansion, backups, or patching activities, and rarely get any time to add value. These activities don’t differentiate our business from our competition, as everyone has to do this – but once we start using the cloud, our support team will have more time to focus on things that add value to the business and differentiate us from the competition. They have shared lots of ideas and some of the ideas are pretty interesting. I am sure it can add a lot of value to our business. We can focus on what matters to our business.

Board Member 2: So, we won’t be needing backups or patching anymore?

A picture containing text, light

Description automatically generatedGloria: We will still need that, but it just becomes a checkbox activity with the cloud. We select a maintenance window for our workloads and the cloud provider will automate the process of backup, patching, and capacity expansion for us.

Board Member 3: That’s interesting – but what about our third location in Asia? Will it remain as it is or also go the cloud way? I don’t want to renegotiate the lease every time we expand our manufacturing units.

A picture containing text, light

Description automatically generatedGloria: We don’t have to. Cloud providers have facilities all over the globe and we plan to move supporting applications closer to the manufacturing plant in Asia – and we will be able to leverage other global locations too as we expand our manufacturing units. We can go global in minutes.

Board Member 3: That’s good. Do we need to hire local teams in those areas?

A picture containing text, light

Description automatically generatedGloria: No, our team from here can perform remote maintenance – and we hope to get a better connectivity speed and performance because of the cloud provider’s high-speed network.

Board Member 2: Much better. I am fully convinced after hearing you and seeing all the data you presented. Can you also send this report in an email?

A picture containing text, light

Description automatically generatedGloria: Yes, I will email you just after this meeting.

Board Member 1: I am convinced too – and we want to move faster, don’t we? I have heard that our competition is already doing so. We don’t want to be left behind.

A picture containing text, light

Description automatically generatedGloria: Thanks for your support on this. We have a few new team members who have joined us this week to accelerate our project.

Board Member 1: Keep us posted. And all the best. Thanks.

A picture containing text, light

Description automatically generatedGloria: Thank you.

The board members leave the meeting room. Gloria heaves a sigh of relief. She has achieved a milestone, Get buy-in from management, for the cloud project. As she exits the meeting room, she finds Alex and Berta heading toward the coffee machine.

A picture containing text

Description automatically generatedBerta: You seem happy. I am sure the presentation went very well.

A picture containing text, light

Description automatically generatedGloria: Indeed.

A picture containing text

Description automatically generatedBerta: Nice. Want to join us for a coffee?

A picture containing text, light

Description automatically generatedGloria: A little later. I have to send an important email. Enjoy your coffee.

Gloria dashes over to her desk. Berta and Alex casually walk toward the coffee machine.

Providing IT as a utility service

After getting their coffee from the vending machine, Berta and Alex return to their desk.

A picture containing clipart

Description automatically generatedAlex: We should talk a bit more with our colleague, Harold. From what I’ve understood from our meeting, Harold is part of the project, even if he seems a bit reluctant to do it. Seems like he’s free now – why don’t we talk with him a bit?

A picture containing text

Description automatically generatedBerta: I had to deal with this kind of person in my previous job. I really don’t like how they behave with new hires, considering them more as a threat than an asset to the company. He probably thinks that he is going to lose his job because of us; that’s the reason he hasn’t talked with us at all.

A picture containing clipart

Description automatically generatedAlex: Oh, come on! Let’s talk with him a bit, and I’ll show you that you’re wrong!

Harold is focused on a long, complex report when the two young colleagues approach him. Alex addresses him first.

A picture containing clipart

Description automatically generatedAlex: Hey, Harold, how is it going? Are you working on something interesting?

Harold doesn’t say a word. Alex, trying again, points at Harold’s desktop, a black-and-white picture of an old, huge machine.

A picture containing clipart

Description automatically generatedAlex: Oh, you have a cool wallpaper! What is it supposed to be?

Harold: I’m not surprised you don’t recognize it; you are too young. In the old days, this kind of machine was used in factories to generate electricity.

A picture containing clipart

Description automatically generatedAlex: No way! Why would someone have a machine like this when electricity is available at the push of a button? This looks so big – it obviously required a lot of space, lots of maintenance, and tons of money to own.

Harold: That’s why not every factory could afford it. Let me take you a little back in history. In the early days—I guess about a hundred years ago—there was no central way of producing electricity. Every factory used to set up these types of giant machines to produce their own electricity. Obviously, this was a challenge for small businesses, because of the initial cost and ongoing maintenance.

A picture containing clipart

Description automatically generatedAlex: Wow. I didn’t know that.

Harold: Sometimes, a big industrial unit needed two or three of these machines to address the growing demands of electricity, and obviously, a dedicated team would maintain and run it. The whole production process would stop if this machine failed, so it was a very critical piece of machinery – but now, electricity production and distribution have become so much simpler and that’s why this machine is in a museum. When energy companies started producing electricity centrally and began distributing it, the whole scenario changed. Some energy companies used hydropower or coal power, and nowadays, it can be nuclear or solar power. Companies that operated these power stations started setting up a grid of cables all over the place so that they could distribute electricity to consumers. Consumers could be big industries or small households who would just pay for what they use and never pay for the infrastructure cost of setting up the whole power station.

A picture containing clipart

Description automatically generatedAlex: Wow! I did not know that electricity production has come such a long way. I never think about all this when I consume energy at home or in the office. We just press a button to light a bulb and only pay for what we use.

In the meantime, Berta, who was listening to the whole story, considered the challenges that factories had to face in the old days. Suddenly, she realized that Harold’s story was related to their project and to cloud computing in general.

A picture containing text

Description automatically generatedBerta: Hey, Harold, sorry to interrupt you. You are basically talking about the same relationship between how companies manage their on-premises IT infrastructure and how they manage their cloud-based IT infrastructure.

Harold: What?

A picture containing text

Description automatically generatedBerta: Well, as you know for sure, in the early days of computing when companies started to use computers, they started by maintaining a data center—a place to keep, or host, all their applications, servers, networks, and storage. Compare a data center to this giant machine.

Harold: You don’t have to explain what a data center is to me, young lady!

A picture containing text

Description automatically generatedBerta: I’m sure, Harold, but just let me finish. Data centers require a huge amount of capital expenses, and companies such as ours have to keep them running smoothly so that business can run smoothly, and because of that, they hire a team of professionals such as you to maintain and operate them. With business growth, companies may need to add more capacity to their data centers or add more data centers to increase the availability of their applications. This puts an extra burden on companies financially, and they have to focus their time and energy on keeping these data centers running.

Harold: Yes, sometimes we call this activity keeping the lights on.

A picture containing text

Description automatically generatedBerta: Oh, cool – I didn’t know that! This is where the interesting part of the story comes in: with cloud computing, companies don’t have to worry about all of this. They can choose a cloud provider in the same way we choose an electricity provider for our office or house, and they can start by using the resources hosted in the cloud provider’s data centers. These data centers may host ready-to-use applications or the building blocks to build your own custom application. Cloud providers maintain and run data centers all over the world to provide services to their customers, who will pay only for what resources they use – or to use cloud computing terminology, they pay as they go, in the same way that we pay only for the electricity we consume.

Harold: Hmm…

A picture containing text

Description automatically generatedBerta: Cloud providers keep thousands of servers running at scale, so multiple customers can start using it without worrying about setting up their own data centers. This allows their customers to focus on their core activities, usually the development of their applications, and save them from undifferentiated heavy lifting, such as server provisioning, storage expansion, backups, security... Cloud providers provide their resources through the internet; in a similar way, electricity producers distribute their energy through a network of electric wires, grid stations, and other similar components. In both cases, we are still talking about networks:

Figure 1.7 – Comparison between electricity and cloud computing

Figure 1.7 – Comparison between electricity and cloud computing

In summary, if we need some electricity, we just have to sign a contract with an electricity provider and then press a button. In the same way, if companies need IT resources, they sign a contract with a cloud provider and just… press a button! Or maybe I should say… call an API! Hahaha!

A picture containing clipart

Description automatically generatedAlex: Berta, you are amazing! What an excellent way to explain cloud computing to everyone. Let’s use this explanation in next week’s presentation that we have to deliver. Thank you.

Harold: Ah! I’m not sure about all that… Please leave and let me work now! I have stuff to do!

Alex and Berta, convinced about what they’ve said, leave Harold and come back to their desk happier than before. They have just completed one step in their cloud journey and still have a long way to go!

I loved the way this book explains AWS Cloud making it easy to understand and retain concepts.I have gone through several training videos (udemy & Youtube) from Ashish (analogiescloud and the BeSA group), they are incredibly easy to understand , explained with the help of simple analogies making the learning process enjoyable for newbies. The authors have a great way of teaching complex topics with ease especially if you are new to the AWS or Cloud Technology.When I skimmed through the preview of the book.. I was so eager to learn from it , had to get a copy for myself .I am fairly new to AWS so I am grateful to have come across such exceptional trainers like Ashish & the co-authors of the book along with BeSA team. It makes me feel more confident to continue this journey and prepare for transitioning into AWS Cloud.

As a Cloud Evangelist and AWS Authorized Instructor, I seek to uncover the optimal resources that thoroughly explain the complexities of cloud computing. I highly recommend "AWS Cloud Computing Concepts and Tech Analogies" by Ashish Prajapati, Marco Tamassia & Juan Carlos Ruiz. The book was beyond my expectation and will be memorable for anyone going through their cloud computing learning journey.What sets this book apart is its ability to go beyond technical details and cater to a broader audience. It combines entertainment and education through a narrative format, making learning fun and adventurous. The authors introduce relatable personas and skillfully navigate the complexities of cloud computing on AWS, capturing my attention from cover to cover.I connected with Alex and Harold in their cloud computing journey. Their experiences mirrored mine, making the book informative and relatable. The authors make complex concepts easy to understand, allowing readers to apply their knowledge in real-world situations."AWS Cloud Computing Concepts and Tech Analogies" is a great book, and it is practical for beginners and experts and uses storytelling to make learning enjoyable. I highly recommend it.

It’s a great book to explain cloud technologies using analogies in our daily lives. I totally enjoyed reading the book although I have been working on cloud for many years and am familiar with the AWS services mentioned in the book.As a Cloud Architect, my job is to understand client's business requirements and map them to the technical requirements and implementation. This book gives me many ideas and analogies that I can use to explain the technical concepts to non-technical folks easily so that they can understand.What a job well done to Ashish and the other two co-authors! I’m a big fan of Ashish and like his usage of analogies in his BeSA program. If you like his BeSA teaching, you will not be disappointed with this great book.I’m looking forward to the sequel of this book on more advanced AWS technologies such as Data Analytics, Machine Learning, and Generative AI!

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.
