Anything and Everything About Cloud – Session 1

A short conversation
Before the Session:
Sid(SS CEO): We need to bring the cloud into the picture. But why?
Why the session:
Albert(Cloud expert): The best thing about cloud is that it gives you as much power as you want.
Inner Me(Super Excited): Okay, well I need powers. Who doesn’t? Who does not want an unlimited source of power? Ahem Ahem…With great powers comes great responsibility. Damn you Spiderman!!
Into the Session:
Sid: Have you guys come prepared with the questions? Albert will address to each of your queries. It is a series of events that will help you explore how you can bring to use the offerings of the cloud.
Being a bring your own questions(BYOB) event, I would like you to ask as much as you can and as much as you want. We believe in equal opportunity and none of would feel left out.
We all were set, ready and filled with thoughts. Each one of us wanted a piece of the cake Albert was offering to us. But one of us wanted a larger piece of cake for himself. Yes, the one who believed in equal opportunity asked the most number of questions. The response to his questions helped us to understand the origin of Cloud.
Origin of the concept of Cloud
The ideology for this concept is based on the past experiences. Earlier each manufacturing company had their own power plants for generating electricity. They were solely responsible for the electricity they generated.
It was suggested to them that instead of using your resources to manage a complete power plant, they can rent the electricity from a Grid and use it as a service at a much cheaper cost.
This idea synchronised with the thought of the business owners as they now could focus on what they actually set out to do. The concerns which deviated them from their goals were now diminished.
Similarly, the cloud service providers want and have uncomplicated the effort that goes into managing and maintaining a physical server.
What about Private Cloud?
A thought then floated around for some time, why cannot we have a cloud of our own? Why pay someone else for the services which we can use ourselves? Little did we realise that a Cloud is a shared pool of virtual resources available to everyone, everywhere and physical servers are the ones responsible for any cloud, be it public or private.
Either way, there are physical servers in both the cases but in the service model you do not have to manage or maintain any of them and use the capabilities offered by cloud services providers like Azure, AWS, Google Cloud Platform(GCP), etc.
When taking into consideration the services offered under the cloud, we refer to the knowledge shared by Tom Shinder(Program Manager, Azure Security) who defines our roles and the role of cloud service provider.
The abbreviations in the above image are as described:
- PaaS – Platform as a Service
- IaaS – Infrastructure as a Service
- SaaS – Software as a Service
A private cloud is an unnecessary addition to those individuals for whom, privacy is not much of a concern. Apart from the big private organisations like Netflix, Wipro, Uber, Airbnb, Capital One bank and numerous more, every startup is switching to the Cloud platform.
Features of Cloud Computing
They are utilising the ultimate powerhouse and features like:
- Hybrid Development
- Load balancing
- Resource pooling
- Data Processing
- Continuous Security and Compliance
- Data Visualization
- Serverless Computing
- Data Analytics
- Incident Control
- Cost Optimization
Now you must have observed that I have highlighted security. It definitely is a matter of concern for the larger lot of people. Similar thoughts brushed our minds and we wanted to know how is cloud going to tackle these challenges of security.
Does cloud provide enough security?
Architect. He stressed that if NASA, CIA, Department of Defense, the USA amongst the many Governmental Organisation are using the Cloud then why shouldn’t we.
We certainly would not be having confidential/ private files piling up the sizes of Everest. If they entrust its security we should too.
But we must not forget the Security and Compliance which is a shared responsibility between cloud service providers and the customer.
AWS responsibility “Security of the Cloud” – AWS is responsible for protecting the infrastructure that runs all of the services offered in the AWS Cloud. This infrastructure is composed of the hardware, software, networking, and facilities that run AWS Cloud services.
Now we know, there are several aspects that AWS looks after for us.
So shall we put every data to cloud? Every Data? Is there a common ground?? There should be…Phewwww(The head bob said it all)
Hybrid is the only way…not just the only way
Hybrid cloud architecture is very popular for those who have firms beliefs that a chunk of their data should always be with them. Most of their data would be deployed in the cloud for the numerous benefits it has and the information they think would be safe with them could be on the physical servers. Well, this solves the problem, finally. 😀
While talking about hybrid one wonders about the ratio of cloud to physical servers and the amount of input we have to put in ourselves.
The two pizza rule
As Jeff Bezos explains it:
“The more people you pack into a task, the less productive the output of the task will likely be. The solution? Never have a task where two pizzas couldn’t feed the entire group.”
At the end, I realised that I was a bit hungry and the two pizza rule seemed to have decreased the number of people that could be a part of a task. 2 maybe?
I’d love to know how many Pizzas you can eat at one go.
Thanks to all we were able to cover a lot of aspects in the first of many sessions of Anything and Everything about the cloud.
If after the session some would have asked me, who I was?
Who am I?
I’m your friendly neighbourhood Cloud-Man!
