Power of AWS Step Functions

Are you writing Python or Node.js code to do Automation or Pull Reports or Inventory in AWS?

💯 If yes, this post is for you and probably you may end up like this read and learn something new today.

🚨 Spoiler Alert 😅:- Am going to talk about AWS Step Functions.

⭐ Yes, with recent advances rolled out in step functions, we can do lot more than, what we thought it does and what we are doing with it.

🧐 Previously we would have used step functions for cases like :-

✍️Lambda can't run beyond 15 mins, so if we want more wait time for some task, we used to call step functions and wait there and re-trigger lambda to process same event.

✍️To call multiple lambda in sequence or parallel, we would have used it.

🖇️Basically what we do is, always we keep our core logic in lambda and just used step functions for so called "orchestration" to call lambda in different patterns.

If you agree with me, then below are some real time use cases, you can try and unleash the real power of step functions.

🏋️You can stop writing code, if your use case or tasks are like this 👇

🏌️‍♂️ Scan across all tagging supported AWS resources and see if your cost specific tags are applied or not. If not applied, tag it.

🏌️‍♂️Generate an inventory data of IAM roles in your AWS environment without being used and does not have any activity.

🏌️‍♂️ Identify all the S3 buckets in your AWS environment which does not have versioning enabled and enable it.

🏌️‍♂️ Identify the cloudformation stacks which are stale in the AWS environment that need to be removed or have them removed automatically and notify the admin teams of this.

🏌️‍♂️ Examine each IAM role in the AWS environment to see if the admin suggest policy is defined. If not, create one, apply it and make sure the necessary contacts are notified.

☝️ You should be able to accomplish the above mentioned tasks using step functions alone without requiring any code written in Python or Node.js based lambda.

☝️ Above Illustrated things are just few examples of step function, you can do beyond those and unlock many things via step functions.

🎟️ Start using it and see the magic ✨, infinity is your limit.

🚧 Note :- I am not hater of AWS Lambda, don't get angry on me, I myself written many lambda's 😉 am just telling, now step functions can do more, than you think 💪.

Take care, bye!

BIG DATA ANALYTICS

BIG DATA ANALYTICS Have you ever hit upon how Amazon and Flip kart could possible verdict what we want; how the Google auto completes our search; how the YouTube looks into videos we want to watch? When we open YouTube, we will be at sixes and sevens, when we find ads related to what we have searched earlier in the past days. This is where we find ourselves in the era of big data analytics. More than 3 trillion bytes of information are being generated everyday through our smart phones, tablets, GPS devices, etc. Have we thought about what can be done with all these information? This is where the data analytics comes into play. Big data analytics is just the study of future build up to store data in order to extract the behaviour patterns. The entire social networking website gathers our data which are related to our interest which is usually done by using our past search or any other social information. Data analytics will lead to a walkover in near future....

Hidden things About Amazon SageMaker Studio

Did you know about Amazon SageMaker Studio❓ 🤔 Like you, I initially believed that this service was only for data-related tasks and that regular engineers/developers weren't supposed to use it. ✒️ However, after using it for a while, I would suggest that it can help you with more than just data related tasks. In fact, an organization can use SageMaker Studio to bring their entire SDLC 💪. 😬 Because of its data'ish ness like gimick we (normal non-data developers) always felt, "Oh, SageMaker, it's expensive 😱 so no, no don't go that side 🤐." 😷 As a result, we shrank and missed the hidden gem 💎 and its possibilities, as well as the opportunity to utilize such a fantastic and powerful tool 🔥. ✒️ Let me give you some glimpse with a preview of what SageMaker Studio is capable of. ✒️ SageMaker is big service, but in this post am limiting my context towards SageMaker Studio only. ✒️ And mostly, this write-up is for developers who enjoy writin...

A Conversation between Simba and Mufasa about AI

A Conversation between Simba 🐯 & Mufasa 🦁 about AI (Artificial Intelligence) Simba: Dad, have you heard about this thing called AI? Mufasa: Yes, my son. It’s a tool that can help us in many ways. Simba: But what if it takes over everything? What if one day, all the animals in the Pride Lands start asking AI to do their jobs? Mufasa: Simba, remember that while AI can assist us, it cannot replace the heart and spirit of the Circle of Life. Simba: So, you’re saying I shouldn’t worry? Mufasa: Exactly. Embrace AI as a friend, not a foe. It can help you hunt for ideas, but it can’t replace your instincts or your roar! Simba: So, I can still be the king, even with AI around? Mufasa: Of course! Just remember, the true strength of a king lies in his ability to adapt and grow, not just in what tools he uses. Simba: Thanks, Dad! I guess I’ll just have to learn to work with AI instead of worrying about it! Mufasa: That’s the spirit, my son. Now, let’s go find some lunch—AI can’t help ...
