Most commonly used AWS services:

🧵👇🏻

 1. Elastic Compute Cloud (EC2):

EC2 instances are basically servers with an operating system which can be used to run your applications on the internet just like you run your applications on your laptop during development.
2. Relational Database Service (RDS):

RDS is a distributed relational database service.

Amazon RDS is available on several database instance types - optimised for memory, performance or I/O - and provides six familiar database engines to choose from, including:
- Amazon Aurora
- PostgreSQL
- MySQL
- MariaDB
- Oracle Database
- SQL Server
3. Elastic Container Service (ECS):

AWS ECS is a fully managed container orchestration service.

ECS has been a foundational pillar for key Amazon services and it can natively integrate with other services such as Amazon Route 53, Secrets Manager, AWS Identity and
...
...

Access Management (IAM), and Amazon CloudWatch providing you a familiar experience to deploy and scale your containers.
4. ElastiCache:

Amazon ElastiCache works as a high throughput and low latency in-memory data store and cache to support the most demanding applications requiring sub-millisecond response times.
5. Simple Storage Service (S3):

As the name suggests S3 provides low cost object storage service with high scalability, data availability, security and performance.

S3 can be used to store files for use cases like websites, mobile apps, enterprise apps, backup & restore etc.
6. Simple Queuing Service (SQS):

SQS is a fully managed message queuing service that enables you to decouple and scale micro services independently. Using SQS you can send, store and receive messages between different components at any volume.
This helps you to build highly scalable and distributed applications.

SQS offers two types of message queues:
- Standard Queues
- FIFO Queues
7. Load Balancer:

Load Balancer is a critical component in any distributed system which sits between a client and a server, accepts incoming requests, and routes them across a a cluster of servers to handle the load.
8. Route 53:

Route53 a highly available and scalable DNS service from AWS. If you don't know what a DNS service is, it's basically the service which routes end users to Internet applications by translating names into numeric IP addresses.
9. AWS Lambda:

AWS Lambda allows you to run your services without provisioning or managing servers. You only pay for the compute time used, whereas in EC2 instances which are up 24/7 you need to pay for that whole time for which these servers are up.
10. Amazon Virtual Private Cloud (VPC):

AWS VPC is one of the core components within AWS which works with multiple other components to secure applications, logically isolate section of AWS Cloud where you can launch resources within a virtual network.

How should one approach System Design questions during an interview?

Here's the step by step guide:

🧵👇🏻

System design interviews are generally open ended discussions. There's no one right answer.

The main focus in this round is to see your thought process and whether you'll be able to design a minimal system keeping future scale in mind and by following the standard principles.

Know that many interviewers deliberately make it hard to see how you approach a given problem.

You cannot possibly design a complex system in 1-2 hours which engineers usually take months to years to design, develop and build.

So this is how you should approach this round:

1. Clarify the requirements: As mentioned earlier the questions are generally very open ended. So you need to ask a lot of question to set the scope clear for the discussion.

Example: "Design an application like Twitter"

Twitter has a lot of features like:
- Post tweet
- Home timeline
- Profile timeline
- Analytics
- Likes
- Retweets
- Following
- Bookmark
- Trending etc

You get the idea!

One of the big promises of software is composability. You can build rich, powerful experiences out of basic building blocks.

APIs add new things to the toolbox. For example: Treasury, which lets an app/platform store, move, and track a business’

I've been a small business owner and can talk at length about SMB banking, and will later, but let's put on the software developer hat right now.

Lots of software talks about money, keeps records about money, does calculations about money, but can't *touch* money.

This is extremely frustrating when you're building SaaS apps for businesses, because you have total control over your UX right until your app needs to touch money... at which point all data about it lives in a silo you can't access.

So you generally push work to the operator.

For example, suppose you’re writing a business-in-a-box system for electricians, including an invoicing feature.

You need to be able to read bank transactions to reconcile. You probably can't. The owner can. So you ask the owner to do mind-numbing work a computer does better.

It sure would be great if your business customers had bank accounts you could actually introspect and operate on their behalves! You could just get the list of incoming payments and match against the invoices.

There is some software to write but it is not rocket science.

Guruvayur Sri Krishna & Coconut with Horns.
#Krishnaleela
#Bhakthi
🕉
We’ve all grown up listening to stories of Shri Krishna. This one is a famous story of Shri Krishna in Guruvayur Temple, also called Dakshina Dwaraka.


There lived a villager who planted coconut saplings and had promised that he would offer the 'first coconut' from each of his coconut trees to "Guruvayurappan". When the trees started to yield coconuts, he collected the first coconut from all the trees in a sack 👇


and set forth to Guruvayur.

On the way he was stopped by a robber who asked all the items in the sack. The villager told the robber that the coconuts in the sack belonged to Guruvayurappan and so he was unable to hand it over.
@SriramKannan77 @Jayalko1


The robber with anger asked the villager "Is Guruvaurappan's coconut any different? Does it have horns ?".
Saying so the robber pulled the sack forcefully out of the villager's hand, and coconuts came out..👇


To their astonishment each and every coconut in the sack had horns! Even today, the coconut with horns are displayed in the temple for devotees to see.

This post is pretty bizarre, but it manages to hit on so many false beliefs that I've seen hurt junior data scientists that it deserves some explicit

(1) The notion that R is well-suited to "building web applications" seems totally out of left field. I don't feel like most R loyalists think this is a good idea, but it's worth calling out that no normal company will be glad you wrote your entire web app in R.

(2) It is true that Python had some issues historically with the 2-to-3 transition, but it's not such a big deal these days. On the flip side, I have found interesting R code that doesn't run in modern R interpreters because of changes in core operations (e.g. assignment syntax).

(3) "Most of the time we only need a latest, working interpreter with the latest packages to run the code" -- this is where things get real and reveal some things that hurt data scientists. If this sentence is true, it's likely because you don't share code with coworkers.

(3) Really is a broader issue in data science: people only think of what they need to do their work if no one else existed and code was never maintained. Junior data scientists almost always operate on projects they start from scratch and don't have to maintain for long.

VEDIC COSMOLOGY, also known as Hindu Cosmology, and cosmography are both interesting and inspiring. Today’s “modern” Vedic texts originated around 3,000 B.C.E. This is the oldest scientific and the oldest religious doctrine known to the human race.


Our current astronomy of the solar system and universe has its roots in Vedic knowledge. It only shows that man had advanced knowledge of astronomy way before our current civilization came into existence.
We are here to talk about the Vedic version of the planetary system,

starting at the top from the eternal planets to the temporary planetary system within innumerable universes in the material world.

Talking about “cosmic manifestation,” we need to incorporate both spiritual and material existence.


The spiritual realm of the planets is everlasting, and this will forever be beyond what the material universe can encapsulate. The spiritual realm belongs to the “super dimensional” or “anti-material” dimension. It means that it is beyond what we can perceive,


beyond time as a linear dimension, and the space of our vision and perception.

There are innumerable planets, all indestructible and forever lasting. That is what the Vedas say about the spiritual planets. Our concentration here is more towards the material side of things.
